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.
  • Circularly polarized patch radiators of this type are required 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. For example, they are used for transmission 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 to talk on a cellular network handle.
  • a combination antenna with a GPS antenna for local positioning of a mobile Participant and at least one vertically polarized Antenna to talk 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 monopole antenna must therefore be greatly shortened, i.e. the height of the antenna based on the base area must be very low because 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 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 take place on the counterweight surface. It overall, however, this is a different type of antenna with one additional to a GPS antenna Helix 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 In this respect, high current suitability is from these prior publications not to be removed.
  • the object of the present invention is compared to 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 invention is characterized above all in that it succeeded in providing a linearly polarized antenna in this way and incorporate that an optimal radiation pattern given with respect to this linearly polarized antenna is, and that this is equally regarding the circular polarized antenna applies. In other words, it is managed to avoid optimizing the radiation pattern of one type of antenna to deterioration the radiation pattern of the other antenna type leads.
  • the linear antenna radiator can arranged undiminished 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 surface is mounted.
  • These passive radiator or alignment elements or groups of several of these emitter or balancing elements are preferably arranged approximately crosswise to each other. It is important for the decision, however, that this should be done via the Residual counterweight area projecting passive radiator or Adjustment elements not in the plane of the remaining counterweight surface or the patch heater itself, but instead 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.
  • 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.

  • the invention relates neither to a ⁇ / 2 radiator they still have 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.
  • 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, the antenna can also be used for electric locomotives, for example it meets the requirements for personal safety (if for example the high-voltage overhead line wire would fall).
