Description

Dualpolarisierter DipolstrahlerDual polarized dipole emitter
Die Erfindung betrifft einen dualpolarisierten Dipol - strahier nach dem Oberbegriff des Anspruches 1.The invention relates to a dual polarized dipole beam according to the preamble of claim 1.
Mittels dualpolarisierter Antennen können bekanntermaßen zwei orthogonale Polarisationen abgestrahlt oder empfangen werden. Bei entsprechender Verschaltung beider Systeme können diese auch zum Abstrahlen oder Empfangen beliebiger anderer Kombinationen der linearen orthogonalen Polarisationen, wie bspw. einer zirkuläre Polarisation eingesetzt werden.As is known, two orthogonal polarizations can be emitted or received by means of dual-polarized antennas. If the two systems are connected appropriately, they can also be used to emit or receive any other combination of linear orthogonal polarizations, such as a circular polarization.
Dualpolarisierte Antennen besitzen als Primärstrahler üblicherweise Dipolstrahler, Patchstrahler oder Schlitzstrahler. Bei den Dipolstrahlern kommen im wesentlichen als Strukturen das Dipolquadrat, bestehend aus vier Ein- zeldipolen, sowie eine Kreuzdipolanordnung zur Anwendung.Dual-polarized antennas usually have dipole radiators, patch radiators or slot radiators as primary radiators. In the case of the dipole radiators, the structures used are essentially the dipole square, consisting of four individual dipoles, and a cross-dipole arrangement.
Damit können die genannten Strahler sowohl horizontal als auch vertikal sowie mit einer Polarisationsausrichtung in einem Winkel +45° betrieben werden. Man spricht in diesem Falle beispielsweise auch von einer X-polarisierten Antenne, wie diese grundsätzlich aus der DE 1296 27 015 be- kannt ist.This means that the radiators mentioned can be used both horizontally and can also be operated vertically and with a polarization orientation at an angle of + 45 °. In this case one speaks, for example, of an X-polarized antenna, as is known in principle from DE 1296 27 015.
Probleme bestehen bei derartigen dualpolarisierten Antennen dann, wenn beispielsweise Halbwertsbreiten von weniger als ca. 75° bei kompakter Antennenbauweise real- isiert werden sollen. In diesem Falle lassen sich dualpolarisierte Antennen praktisch nur durch Dipolquadrate und/oder durch Verwendung sehr breiter Reflektoren realisieren. Damit verbunden ist ein nicht unerheblicher Verschaltungsaufwand. So müssen beispielsweise zur Speisung der Dipole vier Kabel eingesetzt werden. Nachteilig sind aber auch, insbesondere durch die erforderlichen breiten Reflektoren, die großen Antennenmaße.Problems exist with such dual-polarized antennas when, for example, half-widths of less than approx. 75 ° are to be realized with a compact antenna construction. In this case, dual-polarized antennas can practically only be realized using dipole squares and / or using very wide reflectors. This involves a not inconsiderable amount of wiring. For example, four cables must be used to feed the dipoles. However, the large antenna dimensions are also disadvantageous, in particular due to the wide reflectors required.
Ein weiterer Nachteil besteht insbesondere bei +45°-pola- risierten Dipolantennen darin, daß eine relativ hohe Ver- kopplung bei einer aus Dipolquadraten bestehenden Array- Anordnung festzustellen ist. Diese relativ hohe Ver- kopplung wirkt sich insbesondere bei Antennen mit abstimmbarer Phasenlage der Dipole störend aus (einstellbarer elektrischer Downtilt) .Another disadvantage, in particular in the case of + 45 ° polarized dipole antennas, is that a relatively high coupling can be found in an array arrangement consisting of dipole squares. This relatively high coupling has a disruptive effect, in particular in the case of antennas with a tunable phase position of the dipoles (adjustable electrical down tilt).
Eine weitere Ausführungsform von dualpolarisierten Strahlern ist beispielsweise aus der EP 0 685 900 AI bekannt geworden. Hierbei handelt es sich um einen entsprechend anregbaren Schlitzstrahler . Durch die hierbei notwendige einschränkende Dimensionierung der Schlitz-Speisekopplung ist zudem die Verwirklichung kleiner Halbwertsbreiten auch bei diesem bekannten Stand der Technik nur mittels entsprechend großer Reflektoren möglich.Another embodiment of dual-polarized radiators has become known, for example, from EP 0 685 900 AI. This is an appropriately stimulable slot heater. Because of the necessary restricting dimensioning of the slot-feed coupling, the realization of small half-widths is also possible in this known prior art only by means of appropriately large reflectors.
Ausgehend von dem eingangs genannten Stand der Technik ist es deshalb Aufgabe der vorliegenden Erfindung, einen dualpolarisierten Dipolstrahler zu schaffen, der einfach aufgebaut ist und insbesondere auch im Falle eines Array- Aufbaus unter Verwendung mehrerer dualpolarisierter Strahlermodule eine verbesserte Entkopplung aufweist .Starting from the prior art mentioned at the outset, it is therefore an object of the present invention to provide a dual-polarized dipole radiator which is of simple construction and in particular also has an improved decoupling in the case of an array construction using a plurality of dual-polarized radiator modules.
Die Aufgabe wird erfindungsgemäß entsprechend den im Anspruch 1, 4 oder 5 angegebenen Merkmalen gelöst. Vor- teilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.The object is achieved according to the features specified in claim 1, 4 or 5. Advantageous embodiments of the invention are specified in the subclaims.
Die erfindungsgemäßen dualpolarisierten Dipolstrahler sind gegenüber herkömmlichen Lösungen einfacher aufgebaut, so daß die erfindungsgemäßen Dipolstrahler zum einen kostengünstiger herstellbar sind.The dual-polarized dipole emitters according to the invention have a simpler structure than conventional solutions, so that the dipole emitters according to the invention can be manufactured more economically.
Sie weisen aber auch eine völlig überraschende und von herkömmlichen Lösungen abweichende Struktur auf, die vor allem bei Realisierung eines Antennenarrays verbesserte Werte für die Entkopplung ergeben.However, they also have a structure that is completely surprising and differs from conventional solutions, which results in improved values for the decoupling, especially when an antenna array is implemented.
Das Überraschende ist, daß die erfindungsgemäßen dualpolarisierten Dipolstrahler in elektrischer Hinsicht wie ein Kreuzdipol wirken, in mechanischer konstruktiver Hinsicht demgegenüber aber eher einem Dipolquadrat ähneln.The surprising thing is that the dual-polarized dipole emitters according to the invention act like a cross dipole in electrical terms, in mechanical design terms in contrast, they are more like a dipole square.
Überraschend ist dabei ferner, daß das von seiner räumlich konstruktiven Seite her eher einem Dipolquadrat ähnelnde Antennenmodul bei in Horizontal- und Vertikalausrichtung ausgerichteten Dipolkomponenten in elektrischer Hinsicht ein X-polarisiertes Antennenmodul ergibt, mit anderen Worten in elektrischer Hinsicht eine in ±45° strahlende Antenne .It is also surprising that the spatially constructive side of the antenna module, which more closely resembles a dipole square, results in an X-polarized antenna module in electrical and horizontal directions when the dipole components are aligned horizontally and vertically, in other words an antenna that radiates in ± 45 ° in electrical terms.
Soll demgegenüber die Antenne in Horizontal- und/oder Vertikalrichtung polarisiert strahlen oder empfangen, also in elektrischer Hinsicht die Ausrichtung des Kreuzdipols mit seinen elektrischen Dipolachsen in Horizontal- und Verti- kalrichtung liegen, so müßte das in konstruktiver Hinsicht eher einem Dipolquadrat ähnelnde Modul mit den einzelnen Dipolkomponenten in +45° -Richtung ausgerichtet werden.On the other hand, if the antenna is to transmit or receive polarized polarization in the horizontal and / or vertical direction, that is, in electrical terms, the alignment of the cross dipole with its electrical dipole axes is in the horizontal and vertical directions, this would have to be a module similar to a dipole square in terms of construction individual dipole components in the + 45 ° direction.
Erfindungsgemäß ist dazu vorgesehen, daß jeder der vier Dipole durch eine symmetrische Leitung gespeist wird, und durch die spezielle Art der Zusammenschaltung jeweils die orthogonal aufeinander stehenden benachbarten Dipolhälften zweier benachbarter Dipole gleichphasig erregt werden. Diese symmetrischen oder zumindest im wesentlichen oder annähernd symmetrischen Speiseleitungen bestehen aus zwei Leitungshälften, welche einzeln betrachtet gegenüber einem fiktiven Nullpotential eine unsymmetrische Leitung darstellen. Die Zusammenschaltung der unsymmetrischen Leitungshälften erfolgt erfindungsgemäß in der Art, daß je- weils die zu zwei benachbarten und orthogonal zueinander ausgerichteten Dipolhälften führenden beiden Leitungshälften elektrisch miteinander verbunden sind. Die Einεpeisung des resultierenden Gesamtstrahlers erfolgt dabei über Kreuz. Das heißt, daß die jeweils vorstehend genannten beiden verbundenen Leitungshälften zweier senkrecht aufeinander stehender Dipolhälften über Kreuz mit den beiden Leitungshälften der diametral gegenüberliegenden benachbarten und orthogonal zueinanderstehenden Dipolhälften jeweils miteinander elektrisch verbunden sind, vorzugsweise über Kreuz. Somit wirkt der Gesamtstrahler elektrisch eher wie ein Kreuzdipol, wobei durch die spezielle Ausbildung der von der Mitte herausgehenden Leitungen diese nicht oder nur unwesentlich mitstrahlen. Insofern kann man die jeweils orthogonal aufeinander stehenden benachbarten Dipolhälften, welche ja gleichphasig erregt werden, als Teil eines resultierenden Kreuzdipols auffassen. Aus diesem Grunde wird der erfindungsgemäß aufgebaute Strahler auch als resultierender Kreuzdipol bezeichnet. Vollkommen überraschend ist nunmehr, daß eine breitbandige hohe Ent- kopplung zwischen den Speisepunkten in der ersten Polarisation und in der zweiten, dazu orthogonalen Polarisation, erzielt wird.According to the invention it is provided that each of the four dipoles is fed by a symmetrical line, and the orthogonally adjacent dipole halves of two adjacent dipoles are excited in phase by the special type of interconnection. These symmetrical or at least substantially or approximately symmetrical feed lines consist of two line halves which, when considered individually, represent an asymmetrical line with respect to a fictitious zero potential. The interconnection of the asymmetrical line halves takes place according to the invention in such a way that the two halves are adjacent and orthogonal to each other aligned dipole halves leading two line halves are electrically connected. The resulting total radiator is fed in crosswise. This means that the respectively mentioned two connected line halves of two perpendicular dipole halves are cross-connected to the two line halves of the diametrically opposed adjacent and orthogonally opposed dipole halves each electrically connected, preferably crosswise. The overall radiator thus acts more like a cross dipole, with the special design of the lines going out from the center not or only insignificantly. In this respect, the neighboring dipole halves, which are orthogonally adjacent to one another and which are excited in phase, can be regarded as part of a resulting cross dipole. For this reason, the radiator constructed according to the invention is also referred to as the resulting cross dipole. It is now completely surprising that broadband high decoupling between the feed points in the first polarization and in the second, orthogonal polarization, is achieved.
Die erwähnten mit den jeweiligen Dipolhälften in Verbin- düng stehenden symmetrischen Speiseleitungen sind bevorzugt symmetrisch aufgebaut, wobei, da wie erwähnt die zugehörigen Leitungshälften gegenüber einem Nullpotential für sich genommen unsymmetrisch zueinander angeordnet und gegenphasig eingespeist werden, sich die bevorzugte symme- trische Leitungsanordnung ergibt. Die erfindungsgemäßen Vorteile werden dabei natürlich immer noch erzielt, wenn die symmetrische Speiseleitung nicht 100%ig symmetrisch ist, sondern davon abweicht, wobei mit zunehmend stärkerer Abweichung vom symmetrischen Aufbau der Speiseleitungen der Grad der Entkopplung abnimmt .The symmetrical feed lines mentioned, which are connected to the respective dipole halves, are preferably constructed symmetrically, since, as mentioned, the associated line halves are arranged asymmetrically to one another and fed in phase opposition to a zero potential, the preferred symmetrical line arrangement results. The invention Advantages are of course still achieved if the symmetrical feed line is not 100% symmetrical, but differs therefrom, the degree of decoupling decreasing with increasing deviation from the symmetrical structure of the feed lines.
In einer bevorzugten Ausführungsform der Erfindung wird die jeweilige zum Dipol führende Leitungshälfte der symmetrischen Speiseleitung als mechanische Halterung der Dipolhälfte ausgebildet und diese liegt oder endet bevorzugt in dem gleichen Abstand über dem Reflektor, in dem der Dipol selbst über dem Reflektor angebracht is . Somit kann diese Leitung auch als Teil des resultierenden Kreuzdipols aufgefaßt werden, durch die gegenphasigen Ströme auf den Leitungshälften strahlt diese jedoch nicht oder nur geringfügig mit. Es ergibt sich also hier die gewünschte Aufhebung der Strahlungswirkung und somit eine bessere Bündelung der Dipole. Daher ist völlig überraschend, daß dann durch die entsprechende Verschaltung über Kreuz im Speisepunkt einerseits eine Abstrahlung der in einer +45° -Ebene liegenden Polarisation erzielt wird und andererseits eine breitbandige hohe Entkopplung erreicht wird.In a preferred embodiment of the invention, the respective line half of the symmetrical feed line leading to the dipole is designed as a mechanical holder for the dipole half and this is preferably located or ends at the same distance above the reflector in which the dipole itself is attached above the reflector. Thus, this line can also be understood as part of the resulting cross dipole, but due to the opposite-phase currents on the line halves, it does not or only radiates with it. This results in the desired cancellation of the radiation effect and thus better bundling of the dipoles. It is therefore completely surprising that the corresponding cross connection in the feed point on the one hand results in a radiation of the polarization lying in a + 45 ° plane and on the other hand broadband high decoupling is achieved.
Bevorzugt sind die symmetrischen Speiseleitungen mit ihren jeweils beiden unsymmetrischen Leitungshälften so angeordnet, dass diese bei Draufsicht auf eine Strahleranordnung von einer etwa mittig liegenden Symmetrierung ausgehen und zu den jeweils beiden Anschlußstellen zweier in axialer Verlängerung zueinander liegender Dipolhälften führen. Diese Speiseleitungen können aber auch völlig andersverlaufend angeordnet werden. Beispielsweise ist es auch möglich, diese Leitungshälften der symmetrischen Speiseleitung von der Rückseite eines Reflektorbleches durch dieses hindurch zu führen, wobei die Leitungshälften beispielsweise etwa senkrecht zur Ebene des Reflektorbleches direkt zu den darüber befindlichen Anschlußpunkten der jeweils in axialer Verlängerung liegenden Dipolhälften führen. Ebenso kann die Halteeinrichtung für die Dipolhälften von den mit den Dipolhälften in Verbindung stehenden Leitungshälf en völlig getrennt ausgebildet sein.The symmetrical feed lines are preferably arranged with their two asymmetrical line halves in such a way that when viewed from the top of a radiator arrangement, these start from an approximately central symmetry and to the two connection points of two dipole halves lying axially in relation to one another to lead. However, these feed lines can also be arranged in a completely different way. For example, it is also possible to guide these line halves of the symmetrical feed line from the rear of a reflector plate through this, the line halves leading, for example, approximately perpendicular to the plane of the reflector plate directly to the connection points above them of the dipole halves lying in axial extension. Likewise, the holding device for the dipole halves can be made completely separate from the line halves connected to the dipole halves.
Die jeweils beiden senkrecht zueinander stehenden Halb- dipol -Komponenten sind üblicherweise so angeordnet, daß sie jeweils mit ihren freien Enden auf einen gemeinsamen Schnittpunkt weisen, der die Eckpunkte eines Quadrates bildet. Die Komponenten der Dipolhälften müssen hier nicht in konstruktiver Verbindung stehen, können dies aber. Dabei können die Komponenten metallisch sein oder durch Verwendung von Isolatoren, die in den Eckpunkten des erwähnten Quadrates sitzen, verbunden sein.The two half-dipole components which are perpendicular to one another are usually arranged in such a way that their free ends each point to a common point of intersection which forms the corner points of a square. The components of the dipole halves need not be structurally connected here, but can. The components can be metallic or can be connected by using insulators that are located in the corner points of the square mentioned.
Die Erfindung wird nachfolgend anhand von Ausführungs- beispielen näher erläutert. Dabei zeigen im einzelnen:The invention is explained in more detail below on the basis of exemplary embodiments. The individual shows:

Zur Verdeutlichung der erfindungsgemäßen Unterschiede zu einem herkömmlichen dualpolarisierten Dipolstrahler wird zunächst auf Figur 1 Bezug genommen, in welcher ein derar- tiger dualpolarisierter Dipolstrahler 1 in Form eines Dipolquadrates gezeigt ist.To illustrate the differences according to the invention from a conventional dual-polarized dipole radiator, reference is first made to FIG. 1, in which such a dual-polarized dipole radiator 1 is shown in the form of a dipole square.
Der nach dem Stand der Technik bekannte Dipolstrahler 1 gemäß Figur 1 ist so aufgebaut, daß dessen Dipole 3 lineare Polarisationen mit einem Winkel von +45° und -45° bezogen auf die Vertikale bzw. Horizontale empfangen oder ausstrahlen können. Derartige Antennen- oder Antennenarray werden auch kurz als X-polarisierte Antennen oder Anten- nenarrays bezeichnet. Gemäß Figur 1 sind jeweils vom axialen Mittelpunkt 5 der Antennenordnung versetzt liegend erste Dipole 3" in einer -45° -Ausrichtung und zweite Dipole 3' in einer +45°- Ausrichtung vorgesehen. In Figur 1 ist schematisch an- gedeutet, daß dabei jeweils die beiden gegenüberliegenden Dipole 3' bzw. 3" zu einem Doppeldipol zusammengefaßt sind. Somit sind insgesamt vier Verbindungsleitungen 7 notwendig, um von dem Mittelpunkt 5 aus, d.h. von den im Bereich des Mittelpunktes 5 liegenden Einspeis- oder Zu- sammenschaltpunkten 5' bzw. 5", die Speisung der beiden Polarisationen vorzunehmen.The dipole radiator 1 known from the prior art according to FIG. 1 is constructed in such a way that its dipoles 3 can receive or radiate linear polarizations with an angle of + 45 ° and -45 ° with respect to the vertical or horizontal. Such antenna or antenna arrays are also referred to as X-polarized antennas or antenna arrays. According to FIG. 1, first dipoles 3 "in a -45 ° orientation and second dipoles 3 'in a + 45 ° orientation are provided, offset from the axial center 5 of the antenna arrangement. In FIG. 1 it is indicated schematically that in each case the two opposite dipoles 3 'and 3 "are combined to form a double dipole. A total of four connecting lines 7 are therefore necessary in order to supply the two polarizations from the center 5, ie from the feed-in or interconnection points 5 ′ or 5 ″ located in the region of the center 5.
Anhand von Figuren 2 bis 4 ist nunmehr ein erstes erfindungsgemäßes Ausführungsbeispiel für einen dualpolari- sierten Dipolstrahler gezeigt.A first exemplary embodiment according to the invention for a dual-polarized dipole radiator is now shown with reference to FIGS.
Der in Figur 2 dargestellte Dipolstrahler wirkt - was nachfolgend noch im einzelnen erörtert wird - in elektrischer Hinsicht wie ein mit einer Polarisation von +45° strahlender Dipol, also bspw. wie ein Kreuzdipol. Der in elektrischer Hinsicht als Kreuzdipol 3 wirkende Strahler ist gestrichelt in Figur 2 eingezeichnet. Dieser in elektrischer Hinsicht als Kreuzdipol 3 wirkende Strahler mit einer +45° -Ausrichtung gegenüber der Horizontale wird durch einen elektrischen Dipol 3' (in +45° -Richtung geneigt) und einen dazu senkrechten Dipol 3" (mit -45° gegenüber der Horizontalen geneigt) gebildet. Jeder der beiden in elektrischer Hinsicht gebildeten Dipole 3 ' und 3" umfaßt jeweils die zugehörigen Dipolhälften 3'a und 3'b für den Dipol 3' sowie die Dipolhälften 3"a sowie 3"b für den Dipol 3". In konstruktiver Hinsicht wird dabei die sich elektrisch ergebende Dipolhälfte 3'a durch zwei senkrecht aufeinander stehende Halbdipol -Komponenten 114b und lila gebildet. Im gezeigten Ausführungsbeispiel enden die Halbdipol -Komponenten 114b, lila mit ihren rechtwinklig aufeinderzu laufenden Enden im Abstand voneinander. Sie könnten dort allerdings auch verbunden sein, und zwar sowohl durch eine elektrisch leitende, metallische Verbindung, als auch durch Einfügung eines elektrisch nicht leitenden Elements oder Isolators, um z.B. eine höhere mechanische Stabilität zu gewährleisten. An den Enden der Dipolhälften können diese auch noch mit Abwinkelungen versehen sein.In electrical terms, the dipole radiator shown in FIG. 2 acts - as will be discussed in detail below - like a dipole radiating with a polarization of + 45 °, that is to say, for example, like a cross dipole. The radiator, which acts as a cross dipole 3 in electrical terms, is shown in broken lines in FIG. This radiator, which acts in electrical terms as a cross dipole 3 and has a + 45 ° orientation with respect to the horizontal, is replaced by an electrical dipole 3 '(inclined in the + 45 ° direction) and a dipole 3 "perpendicular thereto (with -45 ° with respect to the horizontal) Each of the two dipoles 3 'and 3 "formed in electrical terms comprises the associated dipole halves 3'a and 3'b for the dipole 3' and the dipole halves 3" a and 3 "b for the dipole 3 ". From a design point of view, the electrically resulting dipole half 3'a is formed by two perpendicular half-dipole components 114b and lilac. In the exemplary embodiment shown, the half-dipole components 114b, lilac end at a distance from one another with their ends running at right angles However, they could also be connected there, both by an electrically conductive, metallic connection, and by inserting an electrically non-conductive element or insulator, in order to ensure, for example, greater mechanical stability, which can also be at the ends of the dipole halves still be provided with bends.
Entsprechend wird die im Uhrzeigersinn nächste Dipolhälfte 3"b des in elektrischer Hinsicht mit -45° -Ausrichtung vorgesehenen elektrischen Dipols 3" durch die beiden Halbdipol-Komponenten 111b und 112a gebildet. Die in Verlängerung zur Dipolhälfte 3'a gebildete zweite Dipolhälfte 3'b wird durch die beiden Halbdipol -Komponenten 112b, 113a und die vierte Dipolhälfte 3"a durch die beiden Halbdipol - Komponenten 113b, 114a in analoger Weise gebildet.Correspondingly, the next dipole half 3 "b in the clockwise direction of the electrical dipole 3", which is provided with an electrical orientation of -45 °, is formed by the two half dipole components 111b and 112a. The second dipole half 3'b formed in extension to the dipole half 3'a is formed in an analogous manner by the two half dipole components 112b, 113a and the fourth dipole half 3 "a by the two half dipole components 113b, 114a.
Die als Dipolquadrat angeordneten Halbdipol -Komponenten werden nunmehr durch jeweils eine symmetrische Speiseleitung 115, 116, 117 bzw. 118 gespeist. Dabei werden beispielsweise die beiden Halbdipol -Komponenten 114b und lila, also jeweils die benachbarten orthogonal zueinander ausgerichteten Halbdipol -Komponenten, über eine gemeinsame Einspeisstelle, hier die Einspeisstelle 15' gleichphasig erregt. Die zu diesen Halbdipol -Komponenten 114b, lila gehörende Anschlußleitungen bestehen aus jeweils zwei Leitungshälften 118b und 115a, welche einzeln betrachtet gegenüber einem fiktiven Nullpotential 20 eine unsymmetri- sehe Leitung darstellen. Entsprechend werden beispielsweise die beiden nächsten Halbdipol-Komponenten 111b und 112a über die Leitungshälften 115b bzw. 116a mit ihrem gemeinsamen Einspeispunkt 5" elektrisch verbunden, usw. Bei dieser Verschaltung ist die jeweils zugehörige symmetri- sehe Speiseleitung gleichzeitig so gestaltet, daß sie die mechanische Fixierung der Dipole, d.h. der Halbdipol -Komponenten, übernimmt. Dabei trägt beispielsweise von der symmetrischen Leitung 115 die eine unsymmetrische Leitungshälfte 115a die Dipolhälfte lila und die von Lei- tungshälfte 115a elektrisch getrennte bevorzugt parallel verlaufende zweite Leitungshälfte 115b die zweite Dipolhälfte 111b. Mit anderen Worten tragen also jeweils die beiden zu einer symmetrischen Leitung 115 bis 118 gehörenden zugehörigen unsymmetrischen Leitungshälften jeweils die beiden in axialer Verlängerung zueinander angeordneten Dipolhälften eines Dipols 111 bis 114. Dadurch, daß die Leitungshälften, welche zu den jeweils benachbarten orthogonal aufeinander stehenden Dipolhälften führen, an ihrem Einspeispunkt elektrisch leitend verbunden sind, ergeben sich vier Zusammenschaltpunkte 15', 5", 15", 5', welche wiederum symmetrisch über Kreuz angespeist werden, wie sich insbesondere auch aus der Darstellung gemäß Figur 5 ergibt. Der dadurch entstehende Gesamtstrahler wirkt nunmehr durch die gleichphasige Erregung der Halbdipol - Komponenten 114b, lila bzw. der Halbdipol -Komponenten 111b und 112a bzw. 112b und 113a bzw. 113b und 114a elektrisch wie ein Kreuzdipol. Durch die spezifische Anordnung der Leitungshälften, die jeweils parallel im geringen Abstand zueinander angeordnet sind und gegenphasig der Strom darin fließt, wird sichergestellt, daß die Leitungshälften selbst keinen nennenswerten Strahlungsbeitrag liefern, jede Strahlung also durch Überlappung ausgelöscht wird.The semi-dipole components arranged as a dipole square are now fed through a symmetrical feed line 115, 116, 117 and 118, respectively. For example, the two half-dipole components 114b and lilac, that is to say the neighboring half-dipole components which are oriented orthogonally to one another, become in phase via a common feed point, here the feed point 15 ' excited. The connecting lines belonging to these half-dipole components 114b, lilac each consist of two line halves 118b and 115a, which, viewed individually, represent an asymmetrical line with respect to a fictitious zero potential 20. Correspondingly, for example, the next two half dipole components 111b and 112a are electrically connected to their common feed point 5 "via line halves 115b and 116a, etc. With this connection, the associated symmetrical feed line is designed at the same time in such a way that it mechanically fixes The dipole, ie the semi-dipole component, carries, for example, the unbalanced line half 115a of the symmetrical line 115a, the dipole half purple and the second line half 115b, which is preferably electrically separated from line half 115a, carries the second dipole half 111b So each of the two associated asymmetrical line halves belonging to a symmetrical line 115 to 118 each carry the two dipole halves of a dipole 111 to 114 arranged in axial extension to one another. The fact that the line halves which are adjacent to each other n If the dipole halves are positioned orthogonally on top of one another and are electrically conductively connected at their feed-in point, there are four interconnection points 15 ', 5 ", 15", 5', which in turn are fed symmetrically crosswise, as can be seen in particular from the illustration in FIG. 5 . The resulting total radiator now acts through the in-phase excitation of the half-dipole components 114b, purple or the half-dipole components 111b and 112a or 112b and 113a or 113b and 114a electrically like a cross dipole. The specific arrangement of the line halves, which are each arranged in parallel at a short distance from one another and the current flows in phase opposition, ensures that the line halves themselves do not make any significant contribution to radiation, that is to say any radiation is extinguished by overlapping.
Der Grundaufbau in Draufsicht auf die Strahleranordnung gemäß Figur 2 zeigt, dass das Strahlermodul eine in Draufsicht vierfache Symmetrie aufweist. Zwei rechtwinklig zueinanderstehende Symmetrieachsen werden durch die symmetrischen Leitungen 115 und 117 bzw. 112 und 118 gebildet, wobei die dritte und vierte Symmetrieachse in Draufsicht auf die Strahleranordnung gemäß Figur 2 dazu um 45° verdreht liegt und durch die sich in elektrischer Hinsicht ergebenden Dipole 3' und 3" gebildet werden.The basic structure in plan view of the radiator arrangement according to FIG. 2 shows that the radiator module has a fourfold symmetry in plan view. Two axes of symmetry standing at right angles to each other are formed by the symmetrical lines 115 and 117 or 112 and 118, the third and fourth axes of symmetry being rotated by 45 ° in a plan view of the emitter arrangement according to FIG. 2 and by the dipoles 3 'resulting in electrical terms and 3 "are formed.
In Figur 3 ist ferner noch an dem Einspeis- und Zusammen- schaltpunkt 5' der jeweils eine Teil der Symmetrierung 21 und im geringfügigen Abstand gegenüberliegend zum Mittelpunkt 5 der andere Teil der Symmetrierung 21a gezeigt, welche einerseits zur mechanischen Befestigung der Dipolstruktur an dem Reflektorblech dient und andererseits den Übergang auf unsymmetrische Speiseleitungen (bspw. Koaxialleitungen) im Zusammenschaltpunkt ermöglicht.FIG. 3 also shows, at the feed-in and interconnection point 5 ', one part of the symmetry 21 and, at a slight distance opposite the center 5, the other part of the symmetry 21a, which on the one hand serves to mechanically attach the dipole structure to the reflector plate and on the other hand enables the transition to unbalanced feed lines (e.g. coaxial lines) at the interconnection point.
Entsprechend wird insbesondere in Figur 3 gezeigt, daß derAccordingly, it is shown in particular in Figure 3 that the
Zusammenschaltpunkt 15' für die Halbdipol -Komponenten 114b und lila sowie der gegenüberliegende Zusammenschaltpunkt 15" für die Halbdipol-Komponenten 112b und 113a im Bereich der Symmetrierung 22 und 180° bzw. dazu gegenüberliegend bei der Symmetrierung 22a gebildet ist, welche ebenfalls wieder einerseits der mechanischen Befestigung der Dipolstruktur an einem rückwärtigen Reflektorblech 33 dient und andererseits den Übergang auf die unsymmetrische Speiseleitung (bzw. Koaxialleitung) im Zusammenschaltpunkt ermöglicht. Dabei ist insbesondere in Figur 3 sehr gut zu sehen, wie über eine Überkreuzschaltung mit einer ersten Schaltungsbrücke 121 und einer dazu um 90° versetzt liegenden zweiten Schaltungsbrücke 122 an den jeweils gegenüberliegenden Symmetrierungen 21 und 21a bzw. 22 und 22a die elektrische Anspeisung erfolgt. Die zuletzt genannten Schaltungsbrücken 121 und 122 sind im Vertikalab- stand zueinander angeordnet, elektrisch also nicht miteinander verbunden.Interconnection point 15 'for the half dipole components 114b and lilac and the opposite interconnection point 15 "is formed for the half dipole components 112b and 113a in the area of the symmetry 22 and 180 ° or opposite thereto in the case of the symmetry 22a, which again also serves on the one hand to mechanically attach the dipole structure to a rear reflector plate 33 and on the other hand the transition to 3 can be seen very clearly, in particular how a crossover circuit with a first circuit bridge 121 and a second circuit bridge 122 which is offset by 90 ° to the opposite symmetries 21 and 21a or 22 and 22a, the electrical feed takes place The last-mentioned circuit bridges 121 and 122 are arranged at a vertical distance from one another, ie they are not electrically connected to one another.
Dabei ist aus Figur 3 auch zu ersehen, dass beispielsweise die stiftförmige Brücke 122 an der in Figur 3 rückwärtig liegenden Hälfte der Symmetrierung 22 mechanisch fest angebracht und dort elektrisch mit der Symmetrierung 22 verbunden ist, wohingegen das gegenüberliegende freie Ende dieser stiftförmigen Brücke durch eine entsprechende größer bemessene Bohrung durch die vordere Hälfte der Symme- trierung 22a hinausragt, ohne mit dieser Symmetrierung 22a elektrisch verbunden zu sein. Dies eröffnet die Möglichkeit, vor der Symmetrierung 22a ein Koaxialkabel zur Anspeisung heraufzuführen, den Außenleiter an geeigneter Stelle an der Symmetrierung elektrisch anzubinden und den Innenleiter an dem freien Ende der Brücke 121 anzuschlie- ßen und darüber die Anspeisung zu bewerkstelligen. Auch der zweite Teile der Brücke 121 ist entsprechend aufgebaut, d.h. mit seinem rückwärtigen Ende an der Symmetrierung 21 mechanisch angebracht und elektrisch damit verbun- den, wohingegen das gegenüberliegende freie Ende durch eine größer bemessene Bohrung ohne elektrische Kontaktie- rung über die in Figur 3 rechts vorne liegende Symmetrierung 21a übersteht. Dort kann das zweite Koaxialkabel von unten kommend beispielsweise parallel zur Symmetrierung verlegt werden, der Außenleiter mit der Symmetrierung elektrisch verbunden und der Innenleiter an dem freien Ende der stiftförmigen Brücke 121 angeschlossen werden.It can also be seen from FIG. 3 that, for example, the pin-shaped bridge 122 is mechanically firmly attached to the rear of the symmetry 22 in FIG. 3 and is electrically connected there to the symmetry 22, whereas the opposite free end of this pin-shaped bridge is connected by a corresponding one larger bore protrudes through the front half of the symmetry 22a without being electrically connected to this symmetry 22a. This opens up the possibility of leading a coaxial cable upstream of the balancing 22a, electrically connecting the outer conductor at a suitable point on the balancing and connecting the inner conductor to the free end of the bridge 121. and to manage the feed. The second part of the bridge 121 is also constructed accordingly, ie mechanically attached with its rear end to the symmetry 21 and electrically connected to it, whereas the opposite free end through a larger bore without electrical contact via the one on the right in FIG. 3 symmetry 21a at the front survives. There, the second coaxial cable coming from below can be laid, for example, parallel to the balancing, the outer conductor electrically connected to the balancing, and the inner conductor connected to the free end of the pin-shaped bridge 121.
Nur der Vollständigkeit halber wird erwähnt, dass auch an- dere Anschlußmöglichkeiten ebenso möglich sind, beispielsweise dergestalt, dass ein Innenleiter zwischen den jeweiligen Symmetrierungen von unten nach oben geführt und dann an geeigneter Stelle am oberen Ende einer zugeordneten Symmetrierung elektrisch angeschlossen wird, um darüber die symmetrische Anspeisung zu ermöglichen. Der Außenleiter kann über einen Teil dieser Strecke mitgeführt oder bereits tieferliegend mit der jeweils gegenüberliegenden Hälfte der Symmetrierung elektrisch verbunden sein. Die möglichen Umsetzungen der Anspeisung sind insoweit nur beispielhaft erläutert.For the sake of completeness, it is mentioned that other connection options are also possible, for example in such a way that an inner conductor is routed from bottom to top between the respective symmetrizations and then electrically connected at a suitable point at the upper end of an assigned symmetrization in order to to enable symmetrical feed. The outer conductor can be carried along over a part of this distance or can be electrically connected to the opposite half of the symmetry at a lower level. The possible implementations of the feed are only explained as examples.
Mit anderen Worten erfolgt die Speisung also über Kreuz zwischen den Einspeispunkten 5', 5" bzw. 15', 15". Die erwähnten elektrischen Leitungshälften 115a bis 118b sind dabei jeweils paarweise symmetrisch zueinander angeordnet, d.h. die benachbarten elektrischen Leitungshälften jeweils zweier benachbart liegender Halbdipol -Komponenten verlaufen in vergleichsweise geringem Abstand zueinander parallel, wobei dieser Abstand bevorzugt dem Abstand 55 zwi- sehen den jeweils aufeinanderzuweisenden Enden der zugehörigen Dipolhälften entspricht, also beispielsweise dem Abstand zwischen den aufeinanderzuweisenden Enden der Dipolhälften lila, 111b usw. Grundsätzlich können dabei die Leitungshälften parallel zu einem rückwärtigen Reflektor- blech in der Ebene der Halbdipol-Komponenten verlaufen. In Abweichung dazu ist in dem Ausführungsbeispiel gemäß Figuren 2 und 3 eine Ausführung gezeigt, bei welcher die auch die Haltereinrichtung für die Halbdipol -Komponenten darstellenden Leitungshälften von ihrer zugeordneten Symme- trierung ausgehend leicht abfallend montiert sind und in Höhe der Halbdipol -Komponenten enden, die parallel zu einem rückwärtigen Reflektorblech 33 angeordnet sein können. Dies hängt mit dem Wellenbereich der zu sendenden oder empfangenden elektromagnetischen Wellen zusammen, da die Höhe der Symmetrierung über dem Reflektorblech 33 etwa λ/4 entsprechen soll und bezüglich der Strahlungscharakteristik es ggf. wünschenswert sein kann, dass die Dipole und Dipolhälften näher gegenüber dem Reflektorblech 33 angeordnet sein sollen.In other words, the supply takes place crosswise between the feed points 5 ', 5 "or 15', 15". The mentioned electrical cable halves 115a to 118b are each arranged in pairs symmetrically to one another, ie the adjacent electrical line halves of two adjacent half-dipole components run parallel to each other at a comparatively small distance, this distance preferably corresponding to the distance 55 between the ends of the associated dipole halves to be facing one another, that is to say, for example, the distance between the ends of the dipole halves to be facing each other purple , 111b etc. In principle, the line halves can run parallel to a rear reflector plate in the plane of the semi-dipole components. In deviation from this, in the exemplary embodiment according to FIGS. 2 and 3, an embodiment is shown in which the line halves also representing the holder device for the half-dipole components are mounted in a slightly sloping manner starting from their assigned symmetry and end at the level of the half-dipole components that end can be arranged parallel to a rear reflector plate 33. This is related to the wave range of the electromagnetic waves to be transmitted or received, since the height of the symmetry above the reflector plate 33 should correspond to approximately λ / 4 and, with regard to the radiation characteristic, it may be desirable that the dipoles and dipole halves are closer to the reflector plate 33 should be arranged.
Aufgrund dieser Anordnung wirkt demzufolge dabei ein Dipol immer gleichzeitig für die +45° und die -45° -Polarisation, wobei allerdings in Abweichung von der räumlich geometrischen Ausrichtung der einzelnen Halbdipolkomponenten in Horizontal- und Vertikalrichtung erst durch die Kombina- tion der Strahleranteile sich die resultierende +45° -Polarisation bzw. -45° -Polarisation, mit anderen Worten also der in elektrischer Hinsicht in Figur 2 eingezeichnete X-polarisierte Kreuzdipolstrahler 3 ergibt. Grundlage für die Wirkungsweise ist, dass sich die Ströme auf den jeweils benachbart und parallel zueinander liegenden Zu- oder Verbindungsleitungen, d.h. z.B. auf den elektrischen Leitungen 115a mit dem Strom auf der elektrischen Leitung 115b sowie der Strom auf der Leitung 116a mit jenem auf der elektrischen Leitung 116b usw. phasenmäßig so überlagern, dass diese nicht oder nur geringfügig mitstrahlen, gleichzeitig ergibt sich bei der Superposition der Ströme in den Speisepunkten eine Entkopplung der Speisepunkte (5', 5") von den Speisepunkten (15', 15").Because of this arrangement, a dipole therefore always acts simultaneously for the + 45 ° and the -45 ° polarization, although, in deviation from the spatial geometric alignment of the individual half-dipole components in the horizontal and vertical directions, only through the combination tion of the radiator components, the resulting + 45 ° polarization or -45 ° polarization, in other words, the X-polarized cross-dipole radiator 3 shown in electrical terms in FIG. 2 results. The basis for the mode of operation is that the currents on the supply or connecting lines which are respectively adjacent and parallel to one another, ie for example on the electrical lines 115a with the current on the electrical line 115b and the current on the line 116a with that on the electrical line 116b etc. overlap in phases in such a way that they do not or only radiate at the same time. At the same time, the superposition of the currents in the feed points results in a decoupling of the feed points (5 ', 5 ") from the feed points (15', 15").
Anhand von Figur 5 ist dargestellt, dass unter Verwendung eines anhand von Figuren 2 bis 4 erläuterten dualpolarisierten Dipolstrahlers 1 auch ein entsprechendes Antennenarray mit mehreren bspw. in vertikaler Anbaurichtung über- einander angeordneten Dipolstrahlern 1 aufgebaut sein kann, die allesamt trotz der horizontal und vertikal ausgerichteten Halbdipol -Komponenten in elektrischer Hinsicht eine in +45° bzw. -45° polarisierte Antenne beschreiben.5 shows that, using a dual-polarized dipole radiator 1 explained with reference to FIGS. 2 to 4, a corresponding antenna array can also be constructed with several dipole radiators 1 arranged one above the other, for example, in the vertical mounting direction, all of which, despite the horizontally and vertically oriented ones In electrical terms, semi-dipole components describe an antenna polarized in + 45 ° or -45 °.
Die in Figur 5 gezeigten Strahleranordnungen sind mit ihrer zugehörigen Symmetrierung jeweils auf einem Reflektorblech 33 angeordnet, welches in Anbaurichtung der einzelnen Strahlermodule an den gegenüberliegenden Seiten mit senkrecht zur Reflektorebene verlaufenden elektrisch lei- tenden Rändern 35 versehen sind. Abweichend von dem Ausführungsbeispiel nach den Figuren 2 bis 5 ist es aber genauso möglich, die elektrische Einspeisung an den Dipolhälften nicht im Bereich der Symmetrierung und den an der Symmetrierung 21, 21a bzw. 22, 22a elektrisch befestigten und gleich die Haltefunktion wahrnehmenden Leitungshälften vorzunehmen. Abweichend dazu ist es möglich, dass die in den Figuren 2 bis 5 bezeichneten Elemente 115a bis 118b nur als nicht leitende Tragelemente für die Dipolhälften ausgebildet sind und die symmetri- sehen Leitungen 115 bis 118 direkt von unten her durch das Reflektorblech 33 hindurch zu den Anschlußenden 215a, 215b, 216a, 216b, 217a, 217b bzw. 218a, 218b erfolgt. Schließlich ist es ebenso denkbar, dass in einem derartigen Fall die Tragelemente 115a bis 118b für die Dipolhälf- ten in konstruktiver Hinsicht völlig anders ausgestaltet und anders verlaufend angeordnet sind, beispielsweise von den Anschlußstellen 215a bis 218b, von der Mitte der Dipolhälften ausgehend oder vom Eckbereich der jeweils senkrecht aufeinander stehenden Dipolhälften senkrecht oder schräg nach unten auf den Reflektor 33 zu verlaufen und dort mechanisch verankert sind.The radiator arrangements shown in FIG. 5, with their associated symmetry, are each arranged on a reflector plate 33 which, in the mounting direction of the individual radiator modules, is provided on the opposite sides with electrically conductive edges 35 running perpendicular to the reflector plane. Deviating from the exemplary embodiment according to FIGS. 2 to 5, it is equally possible not to carry out the electrical feed at the dipole halves in the area of the balancing and the line halves electrically fastened to the balancing 21, 21a or 22, 22a and immediately performing the holding function. Deviating from this, it is possible that the elements 115a to 118b designated in FIGS. 2 to 5 are only designed as non-conductive support elements for the dipole halves and the symmetrical lines 115 to 118 see directly from below through the reflector plate 33 to the connection ends 215a, 215b, 216a, 216b, 217a, 217b and 218a, 218b. Finally, it is also conceivable that in such a case the support elements 115a to 118b for the dipole halves are designed completely differently in terms of construction and arranged differently, for example from the connection points 215a to 218b, starting from the center of the dipole halves or from the corner area each of the dipole halves, which are perpendicular to one another, run vertically or obliquely downward onto the reflector 33 and are mechanically anchored there.
Abweichend dazu ist ferner auch denkbar, dass der Reflektor selbst als Leiterplatine ausgebildet ist, d.h. bei- spielsweise als Oberseite einer Leiterplatine, auf welcher die gesamte Antennenanordnung aufgebaut ist. Die entsprechende Einspeisung kann auf der Rückseite der Leiterplatine vorgenommen werden, wobei von dort ausgehend die elektrischen Leitungshälften auf einem geeigneten Weg zu den erwähnten Anschlußstellen 215a bis 218b verlaufen. Zur Erzielung einer möglichst guten Strahlungscharakteristik ist lediglich darauf zu achten, dass diese Leitungshälften, unabhängig wie sie zu den Anschlußstellen an den Dipolhälften geführt sind, möglichst, d.h. im wesentlichen oder zumindest annähernd parallel zueinander ausgerichtet sind, mit anderen Worten zumindest im wesentlichen oder annähernd eine symmetrische Leitung ergeben. Deviating from this, it is also conceivable that the reflector itself is designed as a printed circuit board, ie, for example, as the upper side of a printed circuit board on which the entire antenna arrangement is built. The corresponding feed can be carried out on the rear side of the printed circuit board, the electrical line halves starting from there running in a suitable way to the mentioned connection points 215a to 218b. to In order to achieve the best possible radiation characteristic, it is only necessary to ensure that these line halves, regardless of how they are led to the connection points on the dipole halves, are aligned as far as possible, ie essentially or at least approximately parallel to one another, in other words at least essentially or approximately symmetrically Lead.
