Definitions
- the invention relates to a dual-polarized, omnidirectional antenna according to the preamble of claim 1.
- An omnidirectional antenna for example, from the WO 2011/120090 A1 known.
- Such omnidirectional omnidirectional device comprises, for example, three antenna array arrangements which are each arranged at a 120 ° angle offset from each other about a central axis, resulting in a triangular structure in axial plan view. This allows each antenna array to cover approximately an azimuth angular range of 120 °.
- Corresponding antennas may include a wide variety of emitters and emitter devices according to the prior art, for example dipoles, so-called vector dipoles, patch emitters, etc. So-called dual-polarized vector emitters are known, for example, from US Pat EP 1 057 224 B1 known.
- Each of the three mutually offset antenna arrays comprises, for example, a plurality of dual-polarized radiator devices arranged one above the other at equal intervals. Via a corresponding feed device, the respective dual-polarized radiators are fed.
- the spotlights can also be fed circularly.
- the two polarization planes are not only perpendicular to one another, but are arranged at an angle of + 45 ° or -45 ° with respect to a horizontally or vertically oriented plane.
- the individual sector antennas can be configured to be MIMO-capable, ie they are part of a reception system with a plurality of input and output signals.
- a vertically polarized antenna for example, from the DE 600 19 412 T2 known. It includes a vertical, elongated support structure with multiple dipoles arranged at different heights along the support structure and connected to a coaxial power cable. Along the construction mentioned, only one dipole is provided per level.
- the dipoles are coplanar and arranged exactly colinear, divided into two groups, which are formed successively on said construction.
- the dipoles in the two groups are oriented in the opposite direction to each other, so that the horizontal polarization components of the two groups are opposite.
- the arrangement is such that a small distance arises between the two dipole groups, which offers the possibility of Adjust the phase centers of the dipoles of both groups, so as to compensate for a small shift due to the effect of the ground plane on the dipoles.
- vertically polarized omnidirectional radiators which radiate or receive only in a polarization that is not MIMO-capable.
- These vertically polarized omnidirectional sources with, for example, three or four panels are connected together around a mast in a same plane to form an omnidirectional diagram. For better roundness, several layers can be twisted together.
- the disadvantage here is that good broadcast properties are only possible for a small frequency range (due to the geometric arrangement, this results in phase-dependent cancellations).
- a multi-sector antenna is for example also from the DE 697 34 172 T2 known.
- a plurality of elemental antennas are used, each having a different directivity in a horizontal plane.
- each elementary antenna is arranged in a vertical plane, wherein at least one of the elementary antennas is positioned at a different height than that of the other elemental antennas.
- the elemental antennas are arranged with respect to a vertical axis of the sector antennas, which is defined such that the elementary antennas are arranged axially symmetrically with respect to the said axis.
- a well-known in the prior art omnidirectional antenna is from the US 6,369,774 B1 known.
- This prior publication describes an antenna in which, for example, one dipole antenna is positioned one above the other in three spaced-apart regions along an X-axis, each of which acts on its own as a front radiator.
- the three dipole antennas mentioned are positioned away from each other along the X-axis and are also surrounded by a first medium with a higher impedance, this medium being surrounded with a higher impedance by a second medium. which has a lower impedance compared to the first medium.
- Other examples include a sector antenna in which three patch emitters are each spaced apart 120 degrees apart along the x-axis.
- a single radiator with a vector dipole of the WO 2008/017386 A1 known.
- This single radiator sits in front of a specifically trained, in plan view square reflector, which is surrounded on all four sides by a reflector web, which protrudes in the beam direction transverse to the reflector plane, in particular perpendicular thereto.
- the corresponding Vector radiator in the individual reflector fields arranged one above the other has, which is like the single reflector also on all four sides surrounding each radiator circumferentially surrounded by a reflector web.
- the reflector webs serve for beam shaping.
- a generic omnidirectional antenna is out of the EP 0 802 579 A2 known.
- This publication shows an antenna, which is arranged one above the other in the axial direction and offset from one another in each case three, for example, by 120 ° twisted aligned reflector planes. These reflector planes intersect in axial plan view along the central axis in this central axis. In front of the reflector planes corresponding radiators are arranged. These can also be dual-polarized radiators sitting in a section in front of the reflector, which is bounded by a reflector web extending around the radiator.
- Object of the present invention is to provide an improved dual-polarized while omnidirectional antenna or array antennas, which has over conventional solutions an improved Rundstrahl property with the least possible space.
- the inventive solution is based on the known structure, in which several, for example, three offset by 120 ° to each radiating sector antenna devices, in particular antenna arrays may be provided, not in the same altitude, but in the vertical direction (ie in their cultivation direction) offset from one another lie.
- a phase center is understood as meaning those electronic reference points of an antenna from which the electromagnetic antenna radiation appears to be viewed from the point of reception.
- the reflector plane can usually be referred to at least approximately as a phase center, that is usually the central region of a corresponding reflector arrangement of a sector antenna.
- the invention also proposes that between two adjacent and along the central axis staggered sector antennas between a decoupling device is provided.
- This decoupling device consists of at least one reflector web, which is aligned transversely to the reflector plane of the associated reflector.
- Such transverse webs, which are formed on the reflector are, in principle, for example, from the DE 103 16 787 A1 known.
- this is a conventional single-column mobile radio antenna which comprises at least two reflector modules which can be assembled to form an overall reflector, in each case is characterized by lateral longitudinal webs and between the individual radiator arrangements extending transverse webs.
- the at least one reflector plane of each sector antenna is arranged such that the vertical central axis is arranged to extend at a distance from the reflector plane.
- the reflector walls or the reflector planes lie parallel to the central axis in such a distance that the distance between the reflector plane of a sector antenna and the central axis is smaller than 15% of the column width of an associated antenna column.
- the central axis runs on the side of the reflector plane on which the radiators are also provided.
- the arrangement is such that the central axis passes through the reflector webs.
- phase center of the overall arrangement for the horizontal diagram is identical to the phase center of a single antenna.
- group factor of the overall arrangement is frequency-independent and the omnidirectional diagram thus extremely broadband (it is therefore also suitable for dual-band antennas).
- the roundness of the overall arrangement depends only on the half-width of the individual antenna.
- a decoupling-optimized structure of the individual radiators or directional antennas is also provided.
- This may, for example, circumferential or partially circumferential reflector webs, especially reflector webs, which lie transversely to the respective reflector plane and are formed between the individual, vertically stacked sector antennas.
- an omnidirectional monoband antenna but also, for example, an omnidirectional dual-band antenna or an omnidirectional multiband antenna comprising several bands, which additionally transmit and / or receive dual-polarized or circular-polarized can.
- radiators and radiator devices for example in the form of patch radiators, but also in the form of so-called dipole or vector radiators, as described, for example, in US Pat EP 1 082 728 B1 as well as the EP 1 470 615 B1 are known to be known.
- so-called cup-shaped, slightly larger dimensioned dual-polarized radiator and sitting in the center of smaller sized provided for the higher frequency band range dual polarized radiator can be used.
- a plurality of monoband, dual band or multi-band radiators or radiator devices can also be arranged in each antenna column, usually arranged one above the other in the vertical direction, as in a conventional antenna.
- Each of these antenna columns with the plurality of superimposed radiators are then arranged offset in the circumferential direction about the central axis, that is aligned, ie with different azimuth angles.
- a doubling of the radiator can be effected as explained above, that relative to the respective reflector plane (ie offset by 180 ° lying) oppositely directed radiator devices are provided.
- the common plane in which the phase centers of a column antenna lie or at least approximately may be arranged so that it preferably passes through the central axis or in the vicinity of the central axis.
- the radiator in the one column could be arranged so that their phase centers come to lie exactly or as exactly as possible to the respective central axis of the antenna array, and then that in a for example arranged second antenna column radiating devices in the radial direction, so come to lie in the lateral direction to the central axis, so far as the two columns are not symmetrical to the central axis.
- FIGS. 1 to 3 Reference is made to which a first example is shown.
- FIG. 1 a vertical central axis 1 is shown by dashed lines, which is also referred to below as a mounting axis or cultivation line.
- three sector antennas 5 are arranged one above the other, each offset in the azimuth direction by 120 ° in the circumferential direction to each other, ie radiate offset by 120 ° to each other.
- the three sector antennas 5 are not positioned at the same altitude, relative to their vertical central axis 1 (as is common in the prior art), but offset in the direction of the vertical central axis or cultivation line 1 to each other.
- each of the sector antennas 5 comprises, for example, a dual-polarized emitter 7, for example for a first, higher frequency band (high band) and a further, dual-polarized emitter 9 for a lower frequency band (low band), this sector antenna 5 being arranged in an antenna column 6.
- the vector radiator for the higher frequency band has a structure such as in principle from the EP 1 057 224 B4 or the DE 198 60 121 A1 is known.
- This dual-polarized radiator for the higher frequency band (also referred to below as vector dipole) is arranged, for example, within a so-called cup-shaped dipole, which is likewise designed as a dual-polarized radiator and is suitable for transmission and reception in a low frequency band due to its larger dimensioning.
- a radiator is basically, for example, from EP 1 470 615 B1 to be known as known.
- the two radiators 7 and 9 sit at a same position when viewed from the front perpendicular to the respectively associated reflector 11, which in the example shown in each case a rear reflector to the reflector 13 wall 13, which is arranged in a reflector plane 13 ', wherein in the example shown circumferentially reflector webs 15 are arranged.
- These reflector webs 15 are transversely and preferably in the example shown perpendicular to the reflector plane 13 'and are provided as part of the entire reflector 11 as a circumferential boundary.
- the aforementioned, decoupled reflector structure therefore comprises at least one reflector web 15 ', which is aligned transversely and preferably perpendicular to the reflector plane 13' of the relevant sector antenna 5 and is arranged between two adjacent sector antennas. It should this, especially the decoupling to a adjacent sector antenna serving crosspiece 15 'of the reflector 11 transversely and in particular perpendicular to the connecting line, that is, the central axis 1, aligned.
- an intermediate reflector 17 may be arranged in an intermediate reflector plane 17 'at a parallel distance to the rear reflector wall 13, which is dimensioned smaller than the dual-polarized radiator 9 for the low frequency range, the symmetrization of the corresponding vector radiator 7 a corresponding central opening 17a in this intermediate reflector 17 electrically, without contact penetrates through electrical.
- FIG. 1 in perspective reproduced example includes the mentioned three sector antennas 5, which are aligned in the vertical or central direction 1 offset by 120 ° to each other.
- the structure of all antennas is basically the same, but could also be different from each other.
- Each sector antenna 5, that is, each corresponding antenna system 5 is constructed in the embodiment shown in the manner of a single-column sector antenna, which in the example shown, only one row and thus only a corresponding radiator arrangement for transmission in a higher and lower frequency band.
- two or more sector antennas can also be combined to form a corresponding sector antenna array in the vertical direction in a common antenna column 6.
- additional antenna systems or sector antennas may be provided, which are positioned in a rather laterally, radially or horizontally extending cultivation direction.
- the mentioned vertical central axis 1 is located in each case in the middle of each of the reflector planes 13 'and in the middle of the respective reflector wall 13. This ensures that the phase center of each sector antenna 5, which is approximately centered in the associated reflector plane thirteenth 'or in the reflector wall 13 of each sector antenna 5 is located in an axial plan view of the vertical central axis 1, so that therefore results over the conventional solution significantly improved omnidirectional radiation pattern.
- a double single emitter that is to say a double sector antenna, which in the example shown can each be operated in two frequency bands.
- This double sector antenna 5 comprises a central, in this embodiment, a central reflector 15 which extends perpendicular to the plane of the drawing and has a common reflector wall 13 which lies in said common reflector plane 13 '.
- the two sector antennas 5 are in this example offset by 180 ° to each other and thus positioned symmetrically to the reflector plane 13 '.
- each of the two sector antennas which are rotated by 180 ° relative to one another (as in the preceding example), each have a larger-dimensioned (and eg cup-shaped) dual-polarized one
- Radiator 9 for the lower frequency band and in its central position comprises another, also dual-polarized vector radiator 7, optionally again with the additional in FIG. 4 not visible and from the actual reflector plane 13 'spaced reflector 17, which is also provided again in a reflector plane 17'.
- This structure with a 180 ° offset from each other aligned double sector antenna 5 can now for each of the in FIG. 1 shown three sector antennas can be used, so that can be accommodated in the same high axial structure, but also with the same diameter of the antenna assembly thus formed ultimately six radiators. This not only improves the omnidirectional diagram, but also allows MIMO capability to be realized.
- FIGS. 5 to 7 which, in principle, the example FIGS. 1 to 3 corresponds, with the difference that in deviation to the FIGS. 1 to 3 (Describing an omnidirectional omnidirectional antenna using dual-polarized radiators for a dual-band antenna) vector radiators 7 or 9 are now provided which can only transmit or receive in one frequency band.
- a vector emitter or vector dipole is used, as it is known, for example, from US Pat DE 10 2004 057 774 B4 can be seen for the higher frequency band described there. All shown three, in the vertical direction along the central axis 1 superimposed sector antennas 5 are in a 120 ° angle offset from one another, as is apparent in particular from the view along the central axis according to Figures 6 and 7.
- the arrangement can be such that it can be transmitted and / or received by means of such an omnidirectional antenna in each desired frequency band, specifically for both polarizations.
- suitable radiating means such as patch radiators, may be used instead of the dual polarized vector dipole shown.
- the spacing of the radiators is usually determined as a function of the selected frequency band in which the antenna is to radiate and / or receive. This distance is usually a value between ⁇ / 2 and ⁇ , for example by 0.7 to 0.75 ⁇ , where ⁇ can be the center operating frequency for the frequency band in question.
- this example is a dual-polarized, omnidirectional round radiator for a monoband, in which each sector antenna comprises at least two dual-polarized radiators arranged one above the other in the direction of attachment, as a rule in the direction of the vertical central axis 1.
- each sector antenna comprises at least two dual-polarized radiators arranged one above the other in the direction of attachment, as a rule in the direction of the vertical central axis 1.
- the principle can be developed that three, four, etc. corresponding radiators are arranged one above the other along the central axis. Otherwise, every sector antenna is like the others Examples also, offset at a corresponding angle about the central axis 1 around each other, like the FIGS. 9 and 10 demonstrate.
- the illustrated example according to the FIGS. 8 to 10 is also shown again for a monoband antenna with a plurality of dual polarized emitters arranged one above the other along the central axis 1.
- the individual sector antennas may be formed as dual-polarized dual-band or dual-polarized triband or generally dual-polarized multi-band antennas. If the radiators in the individual sector antennas 5 are to radiate, for example, in two (or more) frequency bands, then a different radiator spacing is usually selected between the individual radiators depending on the operating wavelength, as is generally the case, for example EP 1 082 782 B1 (equals to WO 99/062139 A1 ) is known. This would for example be based on the example according to FIG. 1 or FIG.
- each sector antenna 5 comprises two dual-polarized emitters 9 spaced apart from the central axis 1 for the lower frequency band and, for example, in the same mounting direction, three dual-polarized emitters 7 for the higher frequency band, for example at twice the upper upper frequency band (for example 1800 MHz).
- Band in relation to the lower frequency band (for example, 900 MHz band) two dual polarized radiators 9 for the higher frequency band in the central central position of the two dual polarized radiators for the lower frequency band 9 sit (as in FIG. 1 shown), and that the third dual-polarized radiator 7 for the higher Frequency band between the two centers of the two radiators for the low or higher frequency band can be arranged.
- this omnidirectional omnidirectional comprises not only three sector antennas 5 with dual-polarized radiators, which are arranged only in one antenna column 6, but which are each arranged in two antenna columns 6.
- at least one or a plurality of monoband, dual band or generally multi-band emitters, which are preferably offset in the central direction 1, can be arranged in each antenna column, as was fundamentally explained with reference to the preceding examples.
- the reflector 11 with its reflector wall 13 lies for each of the two antenna columns 6 of each sector antenna 5 in a same reflector plane 13 '.
- Corresponding reflector ribs 15 are provided for each column arrangement which extend around all the radiators 7, 9 belonging to one antenna column, including the mentioned reflector ribs 15 'oriented transversely to the central axis 1 for achieving a decoupling to the next sector antenna.
- transversely extending reflector webs between the individual radiators 7 or 9 may be provided in the individual antenna columns 6.
- the distance between the central longitudinal axes through each of the antenna columns 6 should here again correspond to the usual distance, that is, for example, between ⁇ / 2 and ⁇ with respect to the center operating frequency.
- suitable values are frequently between 0.65 ⁇ and 0.75 ⁇ , that is, for example, around 0.7 ⁇ (relative to the center operating frequency, if it is a Monband antenna, otherwise for dual-band antennas the value of ⁇ is ⁇ ) Center frequency for the lower frequency band as a reference).
- the two antenna columns 6 are each arranged to a vertical plane of symmetry (perpendicular to the reflector plane 13 'standing), so that the vertical central axis 1, the reflector plane 13' passes through, precisely at the separation and connection point between the two antenna columns. 6
- the phase centers of the sector antennas 5 (with the radiators in the two columns 6) seem to be in the central axis 1 or at least approximately there.
- FIGS. 14 to 16 Based on the example according to the FIGS. 14 to 16 is an omnidirectional round radiator with two antenna columns 6 and one or more radiators 7, 9 shown in the individual columns 6, wherein the one antenna column 6, as in the examples according to the FIGS. 1 to 10 with respect to the central axis 1 is arranged so that the three vertically oriented planes of symmetry (which are perpendicular to the respective reflector plane 13 ') of the three in the vertical direction one above the other and twisted arranged sector antennas 5 in the central axis 1 intersect.
- the respective second antenna column 6 is then laterally offset asymmetrically relative to the central axis 1, that is to say arranged radially offset outwards, so that in plan view of FIGS FIGS. 12 and 13 deviating arrangement results.
- the individual sector antennas 5 with the shown at least two antenna columns in the transverse direction, that is to say perpendicular to the central axis 1, can be positioned in different positions, that is to say they do not necessarily have to be inserted only in the antenna FIGS. 11 to 13 or 14 to 16 shown position may be arranged.
- any other deviating relative positions in a different displacement position perpendicular to the central axis are possible.
- an arrangement is preferred in which, in plan view of a corresponding sector antenna with the at least one or the at least two antenna columns, the central axis 1 always lies in an overlapping position relative to the one, two or more column sector antenna 5.
- FIG. 4 It has been shown that at each position of the sector antenna, the number of emitters can be doubled, characterized in that with respect to the reflector 11 and the reflector wall 13, as it were mirror images on both sides a corresponding radiator structure is provided.
- This based on FIG. 4 principle explained in principle can be realized in all examples. This is only an example based on the FIGS. 17 to 19 be shown, which in principle the example of the FIGS. 8 to 10 corresponds, with the peculiarity that the basis of FIG. 4 explained Basic idea is also realized here.
- the antenna structure is basically such that the phase centers of all the column antennas, that is to say at least the column antennas, which are usually mounted consecutively in the vertical direction along the central axis 1, coincide in the central axis 1 or lie at least in the vicinity of the central axis 1.
- the individual sector antennas with their reflectors 11 are arranged around a central axis 1 in such a way that in plan view along the central axis 1, the reflectors 11 and thus also the reflector wall 13 at least partially overlap and overlap.
- this distance is clear and preferably more than half smaller than the usual distance between the phase centers, that is to say in particular the respective reflector plane 13 ', the reflector walls 13 and the central axis X in conventional omnidirectional antenna arrangements which have a triangular structure in plan view, in which the reflector planes are positioned on the sides of an equilateral triangle.
- the reflector walls 13, that is to say the respective reflector plane 13 ' are preferably arranged relative to the central axis 1 such that the radial distance to the central axis 1 of this reflector wall 13 or the reflector plane 13' is smaller than 15%, in particular smaller as 10%, 8%, 6%, 5%, 4%, 3%, 2% and in particular less than 1% of the column width B of the respective antenna column 6 (see FIGS. 1 . 8th or 11 ).
- each sector antenna 5 is arranged so that the central axis 1 lies in the reflector plane 13'.
- the individual sector antennas with their reflectors 11 and the reflector walls can also be arranged offset in a radial distance from the central axis, in order to still realize the advantages described, if this distance is not too large. Therefore, this distance should preferably be less than 15%, in particular less than 10%, 8%, 6%, 5%, 4%, 3%, 2% and in particular less than 1% of the column width B of an antenna column 6.
- FIG. 20 Such an arrangement of the individual reflectors is shown, in which the respective reflector plane 13 'has a small radial offset from the central axis 1 in the aforementioned sense.
- Such an embodiment is considered, inter alia, if, for example, an antenna mast is provided in the free space between the sector antennas arranged in plan view at different elevations should be provided, which is penetrated by the central axis 1.
- the reflector walls 13 are arranged offset with their associated reflector planes 13 'relative to the central axis 1, that the central axis 1 passes through the reflector webs.
- the central axis 1 runs on the side of the reflector plane 13 ', on which the radiators 7 and / or radiators 9 are also provided (in the example according to FIG FIG. 20 the central axis 1 extends on the rear side of the reflector walls 13, ie on the opposite side to the radiators 7/9).
- FIG. 22 For example, to complete the axial top view, there is shown a prior art antenna with three sector antennas, in which the three sector antennas 5 are arranged about the central axis at a 120 ° angle, in which case all sector antennas are mounted at a same elevation since the reflector walls have such a large distance to the central axis 1 that the sector antennas thus formed and in particular their reflectors 11 or reflector walls 13 do not overlap or intersect in plan view.
- the mentioned decoupling-optimized structure of the individual radiator 5 or the directional antennas 5, that is, the one or more sector antennas 5, the mentioned, transversely and in particular perpendicular to the reflector plane 13 'of the reflector wall 13 or the entire reflector 11 extending reflector webs 15 and 15' is provided.
- These reflector webs 15 and 15 ' should preferably have a reflector web height R which is greater than 0.05 ⁇ , where ⁇ is the center frequency in the case of a monoband emitter. In the case of a dual-band or multi-band emitter array, ⁇ is the center frequency of the lowest frequency band.
- the height R of the side wall or the side bars 15, 15 'of the reflector 11 with respect to the reflector plane 13' should not be greater than the height H1, ie the height of the radiator 7 with respect to the reflector plane 13 'and thus not be higher than the height H2, that is, the height of the radiator 9 with respect to the reflector plane 13 '(see FIG. 4 ).
- the reflector web height R of the reflector webs 15, 15 'and 15 is smaller than the height H2 of the dual- or vertical-polarized dipole or vector radiators 9 for the lower frequency band and thus even lower than the height H1 the even higher dual-polar or vertical-polarized dipole or vector radiator 7 for the higher frequency band, as shown in FIGS Figures 2 or 4 can be seen.
- the sector antennas associated with the illustrated omnidirectional radiate or receive in a single polarization may be interconnected via a feed network (this does not apply to the sector operation).
- the sector antennas emitters are provided which transmit and / or receive in two mutually perpendicular polarization planes, all in a common plane of polarization (of, for example, + 45 ° or -45 ° relative to the horizontal) operated emitters can be interconnected via a feed network.

Die Erfindung betrifft eine dualpolarisierte, omnidirektionale Antenne nach dem Oberbegriff des Anspruchs 1.The invention relates to a dual-polarized, omnidirectional antenna according to the preamble of
Eine omnidirektionale Antenne (Rundstrahler) ist beispielsweise aus der
Entsprechende Antennen können die unterschiedlichsten Strahler und Strahlereinrichtungen nach dem Stand der Technik umfassen, beispielsweise Dipole, sogenannte Vektordipole, Patch-Strahler etc.. Sogenannte dualpolarisierte Vektorstrahler sind beispielsweise aus der
Jede der drei versetzt zueinander vorgesehenen Antennenarrays umfasst beispielsweise mehrere in gleichen Abständen übereinander angeordnete dualpolarisierte Strahlereinrichtungen. Über eine entsprechende Speiseeinrichtung werden die jeweils dualpolarisierten Strahler gespeist. Die Strahler können dabei auch zirkular gespeist werden. Die beiden Polarisationsebenen stehen wie üblich bevorzugt nicht nur senkrecht zueinander, sondern sind in einem Winkelbereich von +45° oder -45° gegenüber einer horizontal oder vertikal ausgerichteten Ebene geneigt angeordnet.Each of the three mutually offset antenna arrays comprises, for example, a plurality of dual-polarized radiator devices arranged one above the other at equal intervals. Via a corresponding feed device, the respective dual-polarized radiators are fed. The spotlights can also be fed circularly. As usual, the two polarization planes are not only perpendicular to one another, but are arranged at an angle of + 45 ° or -45 ° with respect to a horizontally or vertically oriented plane.
Ferner können die einzelnen Sektorantennen MIMO-fähig ausgestaltet sein, sind also Teil eines Empfangssystems mit mehreren Eingangs- und Ausgangssignalen.Furthermore, the individual sector antennas can be configured to be MIMO-capable, ie they are part of a reception system with a plurality of input and output signals.
Eine vertikal polarisierte Antenne ist beispielsweise auch aus der
Daneben sind auch vertikal polarisierte Rundstrahler bekannt, die nur in einer Polarisation strahlen oder empfangen, die nicht MIMO-fähig sind. Diese vertikal polarisierten Rundstrahler mit beispielsweise drei oder vier Panels werden um einen Mast in einer gleichen Ebene zu einem Rundstrahldiagramm zusammengeschaltet. Für eine bessere Rundheit können auch mehrere Ebenen verdreht zusammengeschaltet werden. Der Nachteil dabei ist, dass gute Rundstrahleigenschaften nur für einen kleinen Frequenzbereich möglich sind (aufgrund der geometrischen Anordnung ergeben sich dabei phasenabhängige Auslöschungen) .In addition, vertically polarized omnidirectional radiators are known which radiate or receive only in a polarization that is not MIMO-capable. These vertically polarized omnidirectional sources with, for example, three or four panels are connected together around a mast in a same plane to form an omnidirectional diagram. For better roundness, several layers can be twisted together. The disadvantage here is that good broadcast properties are only possible for a small frequency range (due to the geometric arrangement, this results in phase-dependent cancellations).
Eine Multisektorantenne ist beispielsweise auch aus der
Eine nach dem Stand der Technik bekannte omnidirektionale Antenne ist aus der
Um sicherzustellen, dass die einzelnen Antennen voneinander entkoppelt sind, werden die erwähnten drei Dipolantennen längs der X-Achse entfernt voneinander positioniert und sind zudem von einem ersten Medium mit höherer Impedanz umgeben, wobei dieses Medium mit einer höheren Impedanz von einem zweiten Medium umgeben ist, welches eine gegenüber dem ersten Medium niedrigere Impedanz aufweist.To ensure that the individual antennas are decoupled from one another, the three dipole antennas mentioned are positioned away from each other along the X-axis and are also surrounded by a first medium with a higher impedance, this medium being surrounded with a higher impedance by a second medium. which has a lower impedance compared to the first medium.
Andere Beispiele umfassen eine Sektorantenne, bei der drei Patch-Strahler jeweils um 120° unterschiedlich ausgerichtet längs der X-Achse entfernt voneinander angeordnet sind.Other examples include a sector antenna in which three patch emitters are each spaced apart 120 degrees apart along the x-axis.
Ferner ist ein Einzelstrahler mit einem Vektordipol aus der
Zudem ist aus dieser Vorveröffentlichung eine einspaltige Antenne als bekannt zu entnehmen, die entsprechende Vektorstrahler in den einzelnen übereinander angeordneten Reflektorfeldern aufweist, die wie der Einzelreflektor ebenfalls an allen vier Seiten um jeden Strahler umlaufend von einem Reflektorsteg umgeben ist. Die Reflektorstege dienen dabei der Strahlformung.In addition, it can be seen from this prior publication a single-column antenna as known, the corresponding Vector radiator in the individual reflector fields arranged one above the other has, which is like the single reflector also on all four sides surrounding each radiator circumferentially surrounded by a reflector web. The reflector webs serve for beam shaping.
Eine gattungsbildende omnidirektionale Antenne ist aus der
Diese Vorveröffentlichung beschreibt auch jeweils ein Paar von parallel zueinander verlaufenden Reflektorebenen, wobei jedes dieser Paare von Reflektorebenen in unterschiedlichen Azimutwinkeln ausgerichtet sind und in Axialrichtung längs der Zentralachse versetzt zueinander liegen. Dies eröffnet die Möglichkeit, dass an den gegenüberliegenden Seiten der beiden parallel, im Abstand zueinander verlaufenden Reflektoren entsprechende Strahler angeordnet werden können. In diesem Falle sitzen die jeweils beiden parallel zueinander verlaufenden Reflektorebenen eines Reflektor-Paars derart, dass die Zentralachse zwischen diesen Reflektorebenen hindurch verläuft.This prior publication also describes in each case a pair of reflector planes running parallel to one another, wherein each of these pairs of reflector planes are aligned at different azimuth angles and offset in the axial direction along the central axis. This opens up the possibility that corresponding radiators can be arranged on the opposite sides of the two reflectors, which run parallel to one another and at a distance from one another. In this case, the two mutually parallel reflector planes of a reflector pair are seated such that the central axis passes between these reflector planes.
Aufgabe der vorliegenden Erfindung ist es eine verbesserte dualpolarisierte und dabei omnidirektionale Antenne oder Gruppenantennen zu schaffen, die gegenüber herkömmlichen Lösungen eine verbesserte Rundstrahleigenschaft bei möglichst geringem Bauraum aufweist.Object of the present invention is to provide an improved dual-polarized while omnidirectional antenna or array antennas, which has over conventional solutions an improved Rundstrahl property with the least possible space.
Die Erfindung wird entsprechend den im Anspruch 1 angegebenen Merkmalen gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.The invention is solved according to the features specified in
Die erfindungsgemäße Lösung geht von dem bekannten Aufbau aus, bei welchem mehrere, beispielsweise drei um 120° versetzt zueinander strahlende Sektor-Antenneneinrichtungen, insbesondere Antennenarrays, vorgesehen sein können, die nicht in gleicher Höhenlage, sondern in Vertikalrichtung (also in ihrer Anbaurichtung) versetzt zueinander liegen. Dies eröffnet die Möglichkeit, dass jede einzelne Sektorantenne, bezogen auf ihre Zentral- oder Anbauachse, entgegengesetzt zu ihrer Strahlungsrichtung (in Abweichung zum gattungsbildenden Stand der Technik) versetzt liegend montiert wird, so dass letztlich die Phasenzentren in Draufsicht auf die diversen Sektorantennen deckungsgleich zu liegen kommen. Unter einem Phasenzentrum versteht man dabei jene elektronischen Referenzpunkte einer Antenne, von denen die elektromagnetische Antennenstrahlung vom Empfangsort aus betrachtet auszugehen scheint.The inventive solution is based on the known structure, in which several, for example, three offset by 120 ° to each radiating sector antenna devices, in particular antenna arrays may be provided, not in the same altitude, but in the vertical direction (ie in their cultivation direction) offset from one another lie. This opens up the possibility that each sector antenna, relative to its central or mounting axis, opposite to its radiation direction (in deviation from the generic state of the art) mounted offset, so that ultimately the phase centers in plan view of the various sector antennas to be congruent come. A phase center is understood as meaning those electronic reference points of an antenna from which the electromagnetic antenna radiation appears to be viewed from the point of reception.
Dabei kann die Reflektorebene in der Regel zumindest näherungsweise als Phasenzentrum bezeichnet werden, das heißt üblicherweise der mittlere Bereich einer entsprechenden Reflektoranordnung einer Sektorantenne.In this case, the reflector plane can usually be referred to at least approximately as a phase center, that is usually the central region of a corresponding reflector arrangement of a sector antenna.
Da somit für alle Sektorantennen dieser Referenzpunkt identisch ist, wird dadurch eine eklatante Verbesserung der Rundstrahleigenschaften realisiert.Since this reference point is thus identical for all sector antennas, a blatant improvement of the round-beam characteristics is thereby realized.
Da dadurch alle Sektorantennen näher an der zentralen Vertikal- oder Anbauachse liegend angeordnet sind, ergibt sich insgesamt - bei zwar vertikal größerer Gesamthöhe - eine vom Durchmesser her schmälere Antennenanordnung. Da der Durchmesser der Gesamtanordnung im Rahmen der Erfindung wesentlich kleiner ist als bei Lösung nach dem Stand der Technik, ist somit auch der optische Einfluss der Gesamtanordnung im Rahmen der Erfindung geringer. Ferner reduziert sich auch die Windlast bei der erfindungsgemäßen Lösung.Since all sector antennas are thus arranged closer to the central vertical or mounting axis, the overall result is an antenna arrangement which is narrower in diameter, although the overall height is larger vertically. Since the diameter of the overall arrangement is considerably smaller in the context of the invention than in the case of the solution according to the prior art, the optical influence of the overall arrangement within the scope of the invention is thus also lower. Furthermore, the wind load is reduced in the inventive solution.
Die Erfindung schlägt ferner vor, dass zwischen zwei benachbarten und längs der Zentralachse versetzt zueinander angeordneten Sektorantennen zwischen eine Entkopplungseinrichtung vorgesehen ist. Diese Entkopplungseinrichtung besteht aus zumindest einem Reflektorsteg, der quer zur Reflektorebene des zugehörigen Reflektors ausgerichtet ist. Derartige Querstege, die am Reflektor ausgebildet sind, sind zwar grundsätzlich beispielsweise aus der
Gemäß der Erfindung ist dabei die zumindest eine Reflektorebene einer jeden Sektorantenne so angeordnet, dass die vertikale Zentralachse in einem Abstand zur Reflektorebene verlaufend angeordnet ist.According to the invention, the at least one reflector plane of each sector antenna is arranged such that the vertical central axis is arranged to extend at a distance from the reflector plane.
Die Reflektorwände oder die Reflektorebenen liegen dabei in einem derartigen Abstand parallel zur Zentralachse, dass der Abstand zwischen der Reflektorebene einer Sektorantenne und der Zentralachse kleiner ist als 15% der Spaltenbreite einer zugehörigen Antennenspalte. Dabei verläuft die Zentralachse auf der Seite der Reflektorebene, auf der auch die Strahler vorgesehen sind.The reflector walls or the reflector planes lie parallel to the central axis in such a distance that the distance between the reflector plane of a sector antenna and the central axis is smaller than 15% of the column width of an associated antenna column. The central axis runs on the side of the reflector plane on which the radiators are also provided.
Dabei ist die Anordnung derart, dass die Zentralachse die Reflektorstege durchsetzt.The arrangement is such that the central axis passes through the reflector webs.
Dadurch ergibt sich ein geringer Bauraum.This results in a small space.
Als Vorteil ergibt sich im Rahmen der Erfindung dabei auch, dass das Phasenzentrum der Gesamtanordnung für das Horizontaldiagramm identisch mit dem Phasenzentrum einer Einzelantenne ist. Dadurch ist der Gruppenfaktor der Gesamtanordnung frequenzunabhängig und das Rundstrahldiagramm somit extrem breitbandig (es ist somit auch für Dualbandantennen geeignet). Die Rundheit der Gesamtanordnung hängt nur noch von der Halbwertsbreite der Einzelantenne ab.An advantage in the context of the invention is also that the phase center of the overall arrangement for the horizontal diagram is identical to the phase center of a single antenna. As a result, the group factor of the overall arrangement is frequency-independent and the omnidirectional diagram thus extremely broadband (it is therefore also suitable for dual-band antennas). The roundness of the overall arrangement depends only on the half-width of the individual antenna.
In einer bevorzugten Ausführungsform der Erfindung ist ferner ein entkopplungsoptimierter Aufbau der Einzelstrahler bzw. Richtantennen vorgesehen. Dieser kann beispielsweise umlaufende oder abschnittsweise umlaufende Reflektorstege aufweisen, vor allem Reflektorstege, die quer zur jeweiligen Reflektorebene liegen und zwischen den einzelnen, vertikal übereinander angeordneten Sektorantennen ausgebildet sind.In a preferred embodiment of the invention, a decoupling-optimized structure of the individual radiators or directional antennas is also provided. This may, for example, circumferential or partially circumferential reflector webs, especially reflector webs, which lie transversely to the respective reflector plane and are formed between the individual, vertically stacked sector antennas.
Ebenso ist es im Rahmen der Erfindung möglich, nicht nur eine omnidirektionale Monoband-Antenne zu realisieren, sondern beispielsweise auch eine omnidirektionale Dual-band-Antenne oder eine noch mehrere Bänder umfassende omnidirektionale Multiband-Antenne, die zudem dualpolarisiert oder zirkularpolarisiert senden und/oder empfangen kann.Likewise, it is possible within the scope of the invention not only to realize an omnidirectional monoband antenna, but also, for example, an omnidirectional dual-band antenna or an omnidirectional multiband antenna comprising several bands, which additionally transmit and / or receive dual-polarized or circular-polarized can.
Dies kann bevorzugt unter Verwendung geeigneter Strahler und Strahlereinrichtungen realisiert werden, beispielsweise in Form von Patchstrahlern, aber auch in Form von sogenannten Dipol- oder Vektorstrahlern, wie sie beispielsweise aus der
Im Rahmen bevorzugter Ausführungsformen und Weiterbildung der Erfindung ist es ebenso möglich, die Anzahl der Strahler auch auf raumsparende Weise zu erhöhen, indem beispielsweise an jeder Stelle, an der eine Sektorantenne vorgesehen ist, bezogen auf die gleiche Reflektorebene, eine weitere in entgegengesetzter Richtung strahlende Sektorantenne eingesetzt wird. Somit ist an jedem Montageort quasi eine doppelte Sektorantenne vorgesehen, die in entgegengesetzten Richtungen strahlt.In the context of preferred embodiments and development of the invention, it is also possible to reduce the number of To increase emitters in a space-saving manner, for example, at each point, where a sector antenna is provided, based on the same reflector plane, another in the opposite direction radiating sector antenna is used. Thus, a double sector antenna is provided at each mounting location, radiating in opposite directions.
Ebenso können in jeder Antennenspalte in der Regel in Vertikalrichtung übereinander angeordnet auch mehrere Monoband-, Dualband oder Mehrband-Strahler oder -Strahlereinrichtungen angeordnet sein, wie bei einer sonst üblichen Antenne. Jede dieser Antennenspalten mit den mehreren übereinander angeordneten Strahlern sind dann in Umfangsrichtung um die Zentralachse herum versetzt angeordnet, das heißt ausgerichtet, also mit unterschiedlichen Azimutwinkeln. Eine Verdopplung der Strahler kann wie oben erläutert dadurch bewirkt werden, dass bezogen zur jeweiligen Reflektorebene (also um 180° versetzt liegend) entgegengesetzt ausgerichtete Strahlereinrichtungen vorgesehen sind.Likewise, a plurality of monoband, dual band or multi-band radiators or radiator devices can also be arranged in each antenna column, usually arranged one above the other in the vertical direction, as in a conventional antenna. Each of these antenna columns with the plurality of superimposed radiators are then arranged offset in the circumferential direction about the central axis, that is aligned, ie with different azimuth angles. A doubling of the radiator can be effected as explained above, that relative to the respective reflector plane (ie offset by 180 ° lying) oppositely directed radiator devices are provided.
Wenn beispielsweise zwei Antenennspalten mit entsprechenden Strahlereinrichtungen verwendet werden, kann die gemeinsame Ebene, in der die Phasenzentren einer Spaltenantenne liegen oder zumindest näherungsweise liegen, so angeordnet sein, dass diese bevorzugt durch die Zentralachse oder in der Nähe der Zentralachse verläuft.For example, if two antenna columns are used with corresponding radiator devices, the common plane in which the phase centers of a column antenna lie or at least approximately, may be arranged so that it preferably passes through the central axis or in the vicinity of the central axis.
In Abweichung davon ist es in einer Weiterbildung der Erfindung aber auch möglich, in gleicher Höhenposition einer Strahlereinrichtung radial nach außen versetzt liegend zur vertikalen Zentralachse noch eine oder eine doppelte weitere Sektorantenne vorzusehen. Mit anderen Worten könnten bei einer derartigen, beispielsweise zweispaltigen Antennenanordnung (wie die Sektorantenne) die Strahler in der einen Spalte so angeordnet sein, dass deren Phasenzentren exakt oder möglichst exakt zur jeweiligen Zentralachse der Antennenanordnung zu liegen kommen, und dass dann die in einer dazu beispielsweise zweiten Antennenspalte angeordneten Strahlereinrichtungen in Radialrichtung, also in Seitenrichtung versetzt zur Zentralachse zu liegen kommen, insoweit also die beiden Spalten nicht symmetrisch zur Zentralachse liegen. Auch dies bietet weitere Vorteile, selbst wenn diese weitere Sektorantenne radial zur vertikalen Zentralachse entfernter positioniert ist. Dadurch lassen sich Mehrspalten-Antennen mit höheren MIMO-Moden realisieren, bei denen die Phasenzentren zwar nicht identisch sind, bei denen sich jedoch gleichwohl eine bestmögliche Rundheit des Strahlungsdiagramms bei hoher Breitbandigkeit ergibt.In a departure from this, however, it is also possible in an embodiment of the invention to displace radially outwards in the same height position of a radiator device lying to the vertical central axis still provide one or a double further sector antenna. In other words, in such a, for example, two-column antenna arrangement (such as the sector antenna), the radiator in the one column could be arranged so that their phase centers come to lie exactly or as exactly as possible to the respective central axis of the antenna array, and then that in a for example arranged second antenna column radiating devices in the radial direction, so come to lie in the lateral direction to the central axis, so far as the two columns are not symmetrical to the central axis. This also offers further advantages, even if this further sector antenna is positioned more remote radially to the vertical central axis. As a result, it is possible to realize multi-slot antennas with higher MIMO modes, in which the phase centers are not identical, but nevertheless result in the best possible roundness of the radiation pattern with high broadband.

Im gezeigten Beispiel sind drei Sektorantennen 5 übereinander angeordnet, die jeweils in Azimutrichtung um 120° in Umfangsrichtung versetzt zueinander ausgerichtet sind, also um 120° versetzt zueinander strahlen.In the example shown, three
Dabei ist aus den Zeichnungen zu entnehmen, dass die drei Sektorantennen 5 nicht in gleicher Höhenlage, bezogen auf ihre vertikale Zentralachse 1 (wie im Stand der Technik üblich), sondern in Richtung der vertikalen Zentralachse oder Anbaulinie 1 versetzt zueinander liegend positioniert sind.It can be seen from the drawings that the three
Jede der Sektorantennen 5 umfasst dazu beispielsweise einen dualpolarisierten Strahler 7, beispielsweise für ein erstes, höheres Frequenzband (Highband) sowie einen weiteren, dualpolarisierten Strahler 9 für ein niedrigeres Frequenzband (Lowband), wobei diese Sektorantenne 5 in einer Antennenspalte 6 angeordnet ist.For this purpose, each of the
Der Vektorstrahler für das höhere Frequenzband weist einen Aufbau auf, wie er grundsätzlich beispielsweise aus der
Dieser dualpolarisierte Strahler für das höhere Frequenzband (nachfolgend auch kurz Vektordipol genannt) ist beispielsweise innerhalb eines sogenannten kelchförmigen Dipols angeordnet, der ebenfalls als dualpolarisierter Strahler ausgebildet ist und aufgrund seiner größeren Bemessung zum Senden und Empfangen in einem niedrigen Frequenzband geeignet ist. Ein derartiger Strahler ist grundsätzlich beispielsweise aus der
Die beiden Strahler 7 und 9 sitzen an einer gleichen Position bei frontseitiger Betrachtung senkrecht auf dem jeweils zugehörigen Reflektor 11, der im gezeigten Beispiel jeweils eine zum Strahler rückwärtige Reflektorwand 13 umfasst, die in einer Reflektorebene 13' angeordnet ist, wobei im gezeigten Beispiel umlaufend Reflektorstege 15 angeordnet sind. Diese Reflektorstege 15 stehen quer und vorzugsweise im gezeigten Beispiel senkrecht zur Reflektorebene 13' und sind dabei als Teil des gesamten Reflektors 11 als umlaufende Begrenzung vorgesehen. Dadurch lässt sich ein entkopplungsoptimierter Aufbau realisieren, das heißt ein Antennenaufbau, bei dem eine jeweilige Sektorantenne 5 optimal von einer darunter oder darüber befindlichen, benachbarten Sektorantenne entkoppelt ist.The two
Der erwähnte, entkoppelte Reflektoraufbau umfasst dazu also zumindest einen Reflektorsteg 15', der quer und vorzugsweise senkrecht zur Reflektorebene 13' der betreffenden Sektorantenne 5 ausgerichtet ist und dabei zwischen zwei benachbarten Sektorantennen angeordnet ist. Dabei soll dieser, vor allem der Entkopplung zu einer benachbarten Sektorantenne dienende Quersteg 15' des Reflektors 11 quer und insbesondere senkrecht zur Verbindungslinie, das heißt der Zentralachse 1, ausgerichtet verlaufen.The aforementioned, decoupled reflector structure therefore comprises at least one reflector web 15 ', which is aligned transversely and preferably perpendicular to the reflector plane 13' of the
Im gezeigten Beispiel kann noch ein Zwischenreflektor 17 in einer Zwischenreflektorebene 17' in einem parallelen Abstand zur rückwärtigen Reflektorwand 13 angeordnet sein, der kleiner dimensioniert ist als der dualpolarisierte Strahler 9 für den niedrigen Frequenzbereich, wobei die Symmetrierung des entsprechenden Vektorstrahlers 7 eine entsprechende Zentralöffnung 17a in diesem Zwischenreflektor 17 elektrisch, galvanisch kontaktierungsfrei durchragt.In the example shown, an intermediate reflector 17 may be arranged in an intermediate reflector plane 17 'at a parallel distance to the

Jede Sektorantenne 5, das heißt jedes entsprechende Antennensystem 5 ist in der gezeigten Ausführungsform nach Art einer einspaltigen Sektorantenne aufgebaut, die im gezeigten Beispiel auch nur eine Reihe und somit also nur eine entsprechende Strahleranordnung zum Übertragen in ein höheres und niedrigeres Frequenzband umfasst. Wie später noch gezeigt wird, können in Vertikalrichtung in einer gemeinsamen Antennenspalte 6 auch zwei oder mehrere Sektorantennen zu einem entsprechenden Sektor-Antennenarray zusammengefasst sein. Darüber hinaus können auch weitere Antennensysteme oder Sektorantennen vorgesehen sein, die in einer eher seitlich, radial oder horizontal verlaufenden Anbaurichtung positioniert sind.Each
Im gezeigten Beispiel liegt die erwähnte vertikale Zentralachse 1 jeweils mittig in jeder der Reflektorebenen 13' bzw. in der Mitte der jeweiligen Reflektorwand 13. Dadurch ist gewährleistet, dass das Phasenzentrum einer jeden Sektorantenne 5, das näherungsweise in der Regel mittig in der zugehörigen Reflektorebene 13' bzw. in der Reflektorwand 13 einer jeder Sektorantenne 5 liegt, in axialer Draufsicht auf der vertikalen Zentralachse 1 liegt, so dass sich von daher ein gegenüber der herkömmlichen Lösung deutlich verbessertes omnidirektionales Strahlungsdiagramm ergibt.In the example shown, the mentioned vertical

Der Reflektor 11 mit seiner Reflektorwand 13 liegt dabei für jeweils beide Antennenspalten 6 jeder Sektorantenne 5 in einer gleichen Reflektorebene 13'. Entsprechende Reflektorstege 15 sind für jede Spaltenanordnung vorgesehen, die um alle zu einer Antennenspalte gehörenden Strahler 7, 9 herum verlaufen, einschließlich der erwähnten quer zur Zentralachse 1 ausgerichteten Reflektorstege 15' zur Erzielung einer Entkopplung zur nächsten Sektorantenne. In Abweichung beispielsweise von Figur 8 oder von
Bei der Variante gemäß der
Der Abstand zwischen den Mittellängsachsen durch jede der Antennenspalten 6 sollte auch hier wieder dem üblichen Abstand entsprechen, also beispielsweise zwischen λ/2 und λ bezüglich der Mittenbetriebsfrequenz liegen. Entsprechend geeignete Werte liegen häufig zwischen 0,65 λ bis 0,75 λ, also beispielsweise um 0,7 λ (bezogen auf die Mittenbetriebsfrequenz, wenn es sich um eine Monband-Antenne handelt; andernfalls bei Dualband-Antennen ist für λ der Wert der Mittenfrequenz für das niedrigere Frequenzband als Bezugsgröße heranzuziehen).The distance between the central longitudinal axes through each of the

Das heißt, dass die jeweilige vertikale Symmetrieachse 1 zwischen den Antennenspalten 6 parallel zur zugehörigen Reflektorebene 13' verläuft. Die ergibt, dass im Fernfeld die Phasenzentren der Sektorantennen 5 (mit den Strahlern in den beiden Spalten 6) scheinbar in der Zentralachse 1 liegen oder zumindest näherungsweise dort liegen.In the illustrated example, the two

Bei den vorausgehend erläuterten Beispielen unter Verwendung mehrerer Strahler pro Sektorantenne, insbesondere auch bei Verwendung eines zwei- oder mehrspaltigen Antennenaufbaus (Antennenarray) lässt sich vor allem eine MIMO-Fähigkeit des omnidirektionalen Rundstrahlers realisieren bzw. weiter ausbauen und verbessern. Diese verbesserte MIMO-Fähigkeit lässt sich dabei bei bestmöglicher Rundheit des Strahlungsdiagramms sicherstellen.In the previously explained examples using multiple radiators per sector antenna, especially when using a two- or multi-column antenna structure (antenna array) can be especially realize a MIMO capability of omnidirectional round radiator and further expand and improve. This improved MIMO capability can be ensured with the best possible roundness of the radiation pattern.

Wie erwähnt ist der Antennenaufbau grundsätzlich so, dass die Phasenzentren aller Spaltenantennen, das heißt zumindest der Spaltenantennen, die längs der Zentralachse 1 in der Regel in Vertikalrichtung aufeinanderfolgend angebaut sind, in der Zentralachse 1 zusammenfallen oder zumindest in der Nähe der Zentralachse 1 liegen. Diese Phasenzentren liegen dabei in der Regel in der Reflektorebene 13' der Reflektorwand 13. Allgemein gesprochen sind die einzelnen Sektorantennen mit ihren Reflektoren 11 so um eine Zentralachse 1 herum angeordnet, dass sich in Draufsicht längs der Zentralachse 1 die Reflektoren 11 und damit auch die Reflektorwand 13 zumindest teilweise überlappen und überschneiden. Dieser Abstand ist jedenfalls deutlich und bevorzugt mehr als die Hälfte kleiner als der übliche Abstand zwischen den Phasenzentren, das heißt insbesondere der jeweiligen Reflektorebene 13', der Reflektorwände 13 und der Zentralachse X bei herkömmlichen Rundstrahlantennenanordnungen, die einen in Draufsicht dreieckförmigen Aufbau aufweisen, bei welchem die Reflektorebenen an den Seiten eines gleichseitigen Dreiecks positioniert sind.As mentioned, the antenna structure is basically such that the phase centers of all the column antennas, that is to say at least the column antennas, which are usually mounted consecutively in the vertical direction along the
Bevorzugt sind also im Rahmen der Erfindung die Reflektorwände 13, das heißt die jeweilige Reflektorebene 13' bezogen auf die Zentralachse 1 so angeordnet, dass der radiale Abstand zur Zentralachse 1 dieser Reflektorwand 13 oder der Reflektorebene 13' kleiner ist als 15%, insbesondere kleiner ist als 10%, 8%, 6%, 5%, 4%, 3%, 2% und insbesondere auch kleiner ist als 1% der Spaltenbreite B der jeweiligen Antennenspalte 6 (siehe
Die erläuterten Beispiele sind allesamt so beschrieben worden, dass die jeweilige Reflektorebene 13' einer Reflektorwand 13 eines Reflektors 11 einer jeden Sektorantenne 5 so angeordnet ist, dass die Zentralachse 1 in der Reflektorebene 13' liegt. Die einzelnen Sektorantennen mit ihren Reflektoren 11 und den Reflektorwänden können aber auch in einem radialen Abstand zur Zentralachse versetzt angeordnet werden, um immer noch die beschriebenen Vorteile zu realisieren, wenn dieser Abstand nicht zu groß wird. Von daher soll dieser Abstand bevorzugt kleiner als 15%, insbesondere kleiner als 10%, 8%, 6%, 5%, 4%, 3%, 2% und insbesondere auch kleiner als 1% der Spaltenbreite B einer Antennenspalte 6 sein.The illustrated examples have all been described so that the respective reflector plane 13 'of a

Um den erwähnten entkopplungsoptimierten Aufbau der Einzelstrahler 5 bzw. der Richtantennen 5, also der einen oder mehreren Sektorantennen 5 zu realisieren, sind die erwähnten, quer und insbesondere senkrecht zu der Reflektorebene 13' der Reflektorwand 13 oder des gesamten Reflektors 11 verlaufenden Reflektorstege 15 bzw. 15' vorgesehen. Diese Reflektorstege 15 bzw. 15' sollen bevorzugt eine Reflektorsteg-Höhe R aufweisen, die größer als 0,05 λ ist, wobei λ die Mittenfrequenz im Falle eines Monoband-Strahlers ist. Im Falle einer Dualband- oder Multiband-Strahleranordnung ist λ die Mittenfrequenz des niedrigsten Frequenzbandes. Allgemein gesprochen soll die Höhe R der Seitenwand oder der Seitenstege 15, 15' des Reflektors 11 gegenüber der Reflektorebene 13' nicht größer sein als die Höhe H1, also die Höhe der Strahler 7 gegenüber der Reflektorebene 13' und damit aber auch nicht höher sein als die Höhe H2, das heißt die Höhe der Strahler 9 gegenüber der Reflektorebene 13' (siehe
Mit anderen Worten ist also im gezeigten Beispiel die Reflektorsteg-Höhe R der Reflektorstege 15, 15' sowie 15" kleiner als die Höhe H2 der dual- oder vertikalpolarisierten Dipol- oder Vektorstrahler 9 für das niedrigere Frequenzband und damit auch noch niedriger als die Höhe H1 der noch höher bauenden dual- oder vertikalpolarisierten Dipol- oder Vektorstrahler 7 für das höhere Frequenzband, wie dies aus den
In den erwähnten Beispielen und dem an Hand von
Ferner wird angemerkt, dass die zu dem erläuterten Rundstrahler gehörenden Sektorantennen, die in einer einzigen Polarisation strahlen oder empfangen, über ein Speise-netzwerk zusammengeschaltet sein können (dies gilt nicht für den Sektorbetrieb). Soweit für die Sektorantennen Strahler vorgesehen sind, die in zwei senkrecht zueinander stehenden Polarisationsebenen senden und/oder empfangen, können alle in einer gemeinsamen Polarisationsebene (von beispielsweise +45° oder -45° gegenüber der Horizontalen ausgerichtet) betriebene Strahler über ein Speisenetzwerk zusammengeschaltet sein.It is further noted that the sector antennas associated with the illustrated omnidirectional radiate or receive in a single polarization may be interconnected via a feed network (this does not apply to the sector operation). As far as the sector antennas emitters are provided which transmit and / or receive in two mutually perpendicular polarization planes, all in a common plane of polarization (of, for example, + 45 ° or -45 ° relative to the horizontal) operated emitters can be interconnected via a feed network.
