Definitions

  • the antenna into a pane of the vehicle.
  • it has been proposed to use the heat conductor of the rear window of a vehicle for the reception.
  • a vehicle antenna arrangement is known from WO 99/66587.
  • the heating field of a motor vehicle window pane serves in conjunction with additional, not electrically connected to the heating field and located between the heating field and the upper edge of the window pane line structures as an antenna for the reception of LMK, FM and TV signals.
  • a major disadvantage of such an arrangement is the need for a surface, for example in the region of the upper window pane, which is not heated due to lack of heating element and therefore can not be defrosted. Especially for vehicles with small windows of the resulting heatable area of the disc is impermissibly small.
  • a vehicle antenna arrangement is known with on a vehicle window horizontally arranged antenna conductors, which are partially switchable as a heating conductor for heating the vehicle window. There are additional vertical antenna conductors are provided which are galvanically connected to equipotential points of the developing voltage distribution.
  • DE 2 440 439 A shows antenna conductors between heating conductors.
  • the heating conductors are not shared as antenna conductors.
  • the number of antenna connection points should be minimal.
  • a particular advantage of the invention is the cost-effective production. Compared with known antenna arrangements, only one line structure has to be formed in or on only one vehicle pane.
  • the antenna arrangement has at least two additional antenna conductors, which are horizontal and at existing horizontal heating conductors existing vertical heating conductors are arranged vertically, wherein the additional antenna conductors have only a point of contact with the line structure of the antenna arrangement.
  • a vehicle antenna arrangement with arranged in or on a vehicle window horizontal or vertical antenna conductors, which are at least partially switchable as a heat conductor for heating the vehicle window, formed so that the antenna arrangement has at least two additional antenna conductors, which are horizontal and at existing horizontal heating conductors existing vertical heating conductors are arranged vertically, wherein the additional antenna conductors have only a point of contact with the line structure of the antenna arrangement.
  • Another advantage of the invention is the integrated design of passive or active circuit elements which, while providing separate signal paths for the different frequency bands, can be arranged in a single housing. This results in a minimum of mechanical components as well as minimal wiring. Therefore, the antenna arrangement according to the invention is advantageous especially for diversity systems, since a multiplicity of different broadcasting services can be supplied to the electronic components via only one antenna connection point.
  • the antenna conductors located in or on the disk which can be partially switched as a heating conductor, can be designed to be translucent. This allows the most inconspicuous integration of the antenna in the vehicle.
  • the heating conductors can be supplied with voltage via a busbar located on the right and left side or on the upper and lower side of the pane. Such a voltage supply reduces the number of printed conductors present in the line structure, which means a cost advantage for the production.
  • the noise of the additional antenna conductor is designed such that a resonance-like behavior of the antenna arrangement is established over the desired reception range. Due to the symmetrical arrangement of additional antenna conductors, which have only one point of contact with the line structure of the antenna arrangement, such a resonance-like behavior of the antenna arrangement over the entire receiving area can be achieved.
  • the voltage source can be connected via modules with high-frequency high-impedance behavior with the heating conductors in order to suppress the transmitted from the heating current to the antenna conductor electrical system noise.
  • the modules are connected to fulfill the reception task with the antenna.
  • the antenna connection points can be arranged at the respective outer corners of the forming conductor structure, which in turn allows the most inconspicuous integration of the antenna.
  • the antenna arrangement according to the invention is preferably used in rear windows of passenger cars, which may have a metallic frame.
  • FIGS. 1 and 2 in the case of antenna arrangements according to the prior art, provided that all the antenna conductors are to be arranged in a disk, an area is required in the disk which can not be heated.
  • Fig. 1 the area in which the line structure for the reception of the diverse TV signals is arranged, ie that line structure which is connected to the modules 7 c
  • Fig. 2 the area in which the line structures for the Reception of the LMK and the diverse TV signals are arranged, so those line structures that are connected to the modules 7a and 7c.
  • FIG. 3 shows a schematic representation of an antenna arrangement in which the horizontally arranged heating conductors 3 of a vehicle window 1 serve to receive UC, LMK and TV signals, wherein the antenna arrangement additionally comprises vertical antenna conductors 6 which are galvanically connected at equipotential points 5 forming voltage distribution are connected.
  • this antenna system an LMK antenna, two VHF antennas and two TV antennas, which are arranged within two mechanical components.
  • the first mechanical component 13 has passive and / or active components 7b, 7c for fulfilling the reception task for each of a LMK, FM and TV reception.
  • the second mechanical component 14 has passive and / or active components 7a, 7b, 7c for fulfilling the reception task for each VHF and TV reception.
  • the line structures are applied by common methods, irrespective of whether they are single-pane safety glass or laminated safety glass or another type of glass.
  • the described arrangement can be found not only in passenger cars, but also in other vehicles, for example, in ships, use.
  • the antenna connection points are arranged at the outer corner points of the heating field.
  • the heating conductors 3 are arranged substantially horizontally and parallel to one another.
  • the heating current transmitted to the serving as an antenna heating element 3 electrical system interference suppressed by modules 10 with high-frequency high-impedance behavior.
  • Such assemblies 10 are for example an FM / TV choke or a LMK trap.
  • a plurality, but at least two additional antenna conductors 6 are provided, which are also arranged vertically switchable in this embodiment of heating 3 for heating the disc and galvanically connected to the horizontally disposed heating conductors 3 at equipotential points 5 of the forming line structure are.
  • the length of the additional antenna conductor 6 is determined so that sets a resonance-like behavior of the antenna over the entire reception range.
  • FIGS. 4, 5 and 6 show exemplary embodiments of an antenna arrangement according to the invention.
  • the broadband of the antenna array is achieved in that the horizontally arranged heating conductors 3 according to the invention additionally a plurality, but at least two also horizontally arranged antenna conductor 6 are provided, which have only one point of contact with the line structure of the antenna assembly. For this reason, these additional antenna conductors 6 do not serve as heating conductors 3.
  • these additional antenna conductors 6 are each connected to the busbar 4 and arranged symmetrically with respect to one another.
