Definitions
- the invention relates to a mobile antenna, in particular Vehicle antenna for at least one circular and at least one a linear, preferably vertical polarization according to the Preamble of claim 1.
- Such GPS antennas usually consist of one circularly polarized antenna in the form of a patch radiator.
- Such circularly polarized patch radiators need a large counterweight area to ensure that the radiation diagram of the GPS emitter properly trained.
- One too small Counterweight area leads to the fact that the radiation diagram too strong with normal vertical alignment is bundled in the vertical direction, and above all that satellites very low above the horizon more can be received, causing the evaluation errors grow.
- Vertically polarized antennas are usually used in the Mobile radio used. They are used for transmission, for example of calls according to the GSM standard, so in the 900 MHz band and in the 1800 MHz band.
- a combination antenna using at least one circular antenna and at least one vertically polarized antenna i.e. for example a combination antenna with a GPS antenna for local positioning of a mobile Participant and at least one vertically polarized Antenna for talking on a cellular network handle.
- a combination antenna with a GPS antenna for local positioning of a mobile Participant
- at least one vertically polarized Antenna for talking on a cellular network handle.
- two vertically polarized ones Antennas used for example Dual band phones are used, for example, on the 900 MHz band, which is common in Europe in particular and operate on the 1800 MHz band to the other can.
- a greatly shortened ⁇ / 4 monopole antenna as vertically polarized antenna e.g. for the Cellular operation
- the monopoly antenna must therefore be greatly shortened, i.e. the height of the antenna in relation to the base area must be very low, as with increasingly higher construction of this vertically polarized Antenna an increasingly stronger mutual influence between the two antenna systems is, with a significant deterioration in the Radiation diagram and significantly deteriorated results regarding the adaptation or the standing wave ratio (VSWR).
- GB 22 72 575 A is a combination antenna from a vertically polarized omnidirectional antenna and an overlying patch antenna are known, the Counterweight of the patch antenna is comparatively small and also needs to be around the radiation pattern and the Radiation properties of the vertically polarized antenna not adversely affect. The smaller, however the counterweight area becomes, the worse it gets Radiation diagram and the radiation characteristics of the circularly polarized antenna.
- a combination antenna with a circularly polarized one at the top Patch antenna is also from the EP, for example 0 740 361 A1.
- the patch antenna provided above sits on a counterweight surface that is in their size corresponds to the patch antenna.
- Below the Patch antenna and the same-sized counterweight surface extends over a comparatively long axial length a helical antenna, on the dielectric antenna body radiator elements arranged in a helical pattern are.
- the cross section of the antenna body can, for example be round, square, etc.
- additional short radiator elements can be provided, which also helical over part of the length of the antenna body extend downwards from the top base plate, the connection of these additional radiator elements galvanically or by means of a capacitive coupling can be done on the counterweight surface. It deals this is a different type of antenna with an additional helical antenna to a GPS antenna.
- Flachenecker, G "A lightning-protected transistor-oriented Receiving antenna "in NTZ, 22nd year, issue 10, October 1969, pages 557-564 known, a corresponding grounding of the antenna system as such.
- a general one Grounding of an antenna system is also from the EP 0 170 344 A2 can generally be seen as known. Reached this is basically done by choosing one accordingly large cross-section with which the inner conductor Mass is laid. But this does not offer a solution for the Case that one is offset from a mass circular antenna usually over a usually dimensioned (i.e. not strongly dimensioned) inner conductor is fed.
- a solution to achieve one To this extent, high-current suitability is from these prior publications not to be removed.
- the object of the present invention is one opposite the combi antenna, which is nevertheless improved in the prior art to create with favorable antenna characteristics, in particular also for vehicles like electrified rail vehicles, the at least one circularly polarized antenna and at least one linearly, especially vertically polarized Antenna includes.
- the high current safety is ensured by a massive grounding all parts of the antenna including the inner conductor possible, without this affecting the antenna function leads. Due to the high current security Antenna can also be used for electric locomotives, for example, since they meet the requirements for personal security fulfilled (if, for example, the one under high voltage Trolley wire would fall).
- the linear antenna radiator can preferably be shortened arranged in front of a base or mass and be mounted to get an optimal radiation diagram sure.
- the spotlight is usually in the transverse orientation the circularly polarized antenna is preferred in the form of a patch spotlight, but only on a comparatively small residual counterweight area is mounted.
- These passive radiator or alignment elements or groups of several of these emitter or balancing elements are preferably arranged approximately crosswise to one another. What is important for the decision, however, is that this is based on the Passive radiators projecting from the remaining counterweight area Adjustment elements not in the plane of the remaining counterweight surface or the patch heater itself, but to do so run strongly angled, the angling preferably in the direction of the vertical radiator underneath is made.
- An angle of less than 60 ° to 50 ° is preferred Alignment of the linear radiator underneath.
- Favorable angular values are less than 30 °, even at less than 25 °.
- Good values are in the range of 30 ° to 1 °.
- passive radiator or balancing elements can be designed differently, in the form of finger-shaped Strips, electrically conductive grids, beam-like or cylindrical elements, wire-shaped, hollow body-shaped etc.
- the width as the material thickness, the The outer contour and shape can be chosen in a wide range can be varied.
- passive radiator and balancing elements grouped together be, which preferably in plan view each 90 ° apart. In doing so, these Spotlight or alignment elements, even if they are in groups are summarized, are not each identical and be provided.
- the invention also possible by at least minor Adjustments to the effective electrical length, thickness, shape, Material choice etc. of this passive radiator and Adjustment elements and / or through different thickness selection etc. a slightly asymmetrical radiation diagram generate, which is coordinated so that at additional attached protective housing through the protective housing or caused other peculiarities given on site Asymmetries avoided or at least tend to be compensated can be.
- ground plane antennas are known also rods to improve the antenna characteristics exhibit. With such ground plane antennas but only the mirror surface is of importance to achieve a simplified antenna structure.
- the present invention does not relate to either one ⁇ / 2 radiators still have those with a ground plane antenna known rods or wires one with the present Antenna device comparable function. Because an extension the rods known per se from a ground plane antenna in the present antenna type on the one provided there Remaining counterweight area would only become a non-functional one Lead antenna.
- Figure 1 is a vertical antenna cross section, in particular vehicle antenna shown on a Ground lying base plate 1 is mounted.

- the outer conductor 17 " is with the base plate 1 and therefore electrically connected to ground, at 21. How from the axial cross-sectional view according to FIG. 1 can be seen, the feed outer conductor 17 "is ultimately but also connected to the inner conductor 17 ', and indeed via an inner stub 27, which consists of a coaxial Outer conductor 27 ', which is at its base plate 1 opposite end via a radial or Pot-shaped short circuit 27 "with the associated inner conductor 11 "electrically connected and thus short-circuited is.
- the conductor 11 "thus has a double function. On on the inside, it acts as an external conductor for the Coaxial line 11 and on its outside it acts as Inner conductor for the stub 27.
- this branch line 27 corresponds to ⁇ / 4 to the frequency to be transmitted, i.e. in the embodiment shown ⁇ / 4 with respect to the GPS frequency band (1575 MHz band).
- the wall of the inner branch line 27, i.e. of the coaxial outer conductor 27 'and the ground or radial short circuit 27 is thick-walled, to ensure the desired high current safety.
- the outer conductor 17 " is also included the coaxial inner conductor 11 'and the feed inner conductor 17' electrically connected to the coaxial outer conductor 11 ", so that ultimately at the feed point 20 there is a change from inside and outside External conductor takes place.
- the antenna 33 consists of a locking pot 30, the cylinder wall 33 'arranged concentrically to the inner stub 27 and a ring-shaped or floor-shaped short circuit 31 with the coaxial outer conductor 27 'in connection stands.
- the locking pot 30 ends opposite its bottom-shaped short circuit 31 at a short distance 28 in front of the base plate 1.
- the total height between base plate 1 and Patch heater 3 and thus the entire axial length or The height of the antenna 33 corresponds to ⁇ / 2 of the higher one to be transmitted Frequency (in the shown embodiment of the Frequency band 1800 MHz, i.e. of the PCN frequency band), the height of the antenna 33 simultaneously ⁇ / 4 of the lower frequency band to be transmitted, in the exemplary embodiment shown the GSM frequency band (900 MHz band) equivalent.
- the Cylinder wall 33 'of the locking pot 30 over the ring or bottom-shaped short circuit 31 extending to the remaining counterweight surface 9, with which they are electrically connected is extended, the cylinder wall thus formed 33 "together with the cylinder wall 33 ' Antenna 33 forms.
- the antenna 33 thus acts for the higher frequency to be transmitted than ⁇ / 2 radiators and for the lower frequency to be transmitted than ⁇ / 4 radiators.
- the GPS antenna does not have a first one in Figure 1 shown in more detail and only indicated by reference numeral 37 coaxial connector 37 is fed (which of which outgoing coaxial feed line 17 in the area of the feed point 20 penetrates a bore 22 in the base plate 1, i.e. is penetrated at least by the inner conductor 17 ', while the outer conductor 17 "with the base plate 1 electrically connected and ends here), the vertical polarized antenna for transmission of a lower and upper frequency band range (e.g. 900 MHz band, 1800 MHz band) fed via a second coaxial connection 39, its inner conductor 41 'with the cylindrical antenna 33 and its outer conductor 41 "with the base plate 1 electrically is contacted.
