Definitions

  • the invention is based on a vehicle windshield antenna with a heating field, which is provided for both the FM reception and for the LMK reception.
  • the heating field of the disc is often used as an antenna structure.
  • the heating field is intended for VHF and TV reception.
  • a conductor loop at the upper edge of the disc, which is not connected to the heating field, is provided.
  • a major disadvantage of such an arrangement is the need for a surface, z. B. in the upper region of the window, which is not heated due to lack of heating element and thus can not be defrosted. Especially in cars with small windows of the resulting heatable area is impermissibly small.
  • the heating conductors are substantially horizontal and substantially parallel to the metallic boundaries of the disc.
  • the on-board network disturbances transmitted by the heating current to the heating conductors serving as antennas must, as is known, be suppressed by assemblies having high-frequency, high-impedance behavior if the antenna connection point is galvanically connected to the heating field.
  • assemblies having high-frequency, high-impedance behavior if the antenna connection point is galvanically connected to the heating field.
  • For FM / TV reception these are z.
  • B. rod core chokes which are integrated in the Schustromsammlungden line parts and are usually located near the Schustroman relieve the heating field.
  • AM blocking circuit is a very cost-intensive module whose own weight, approx. 200 g, leads to high mechanical loads on both the printed circuit board and the screw connection points and is thus to be regarded as extremely critical within the framework of quality assurance. The vibrations occurring under normal driving conditions cause solder joints to be heavily stressed. In compact vehicles, this AM-blocking circuit is often mounted in the rear tailgate, so that when slamming the flap accelerations of about 50 g can occur and the entire component tears off the screwing points.
  • Antenna arrangements are also known which form antennas for the LMK and FM reception from the galvanically contacted heating field. Again, on-board decoupling filter elements for antenna connection point and heating conductor are necessary ( EP 0269723 B1 . EP 0382895 B1 ).
  • the signals for the FM reception are decoupled separately from a busbar and fed to a corresponding amplifier.
  • a corresponding genus-forming glass antenna from the EP 0 639 868 A1 to be known as known is known.
  • a separate Schuleiterfeld is provided above which the disc has a larger space in which no heating conductors are arranged.
  • a coupling wire is provided on the one hand, which runs parallel to an uppermost arranged heating conductor of the Schuleiterfeldes and is thus electrically coupled centrally. Due to this, no heating current flows through this coupling-out wire.
  • a further antenna coupling wire is provided, which is connected centrally with other antenna wires, which lead to a decoupling member.
  • the object of the present invention is therefore based on the generic EP 0 639 868 A1 to provide an improved glass antenna using a Schuleiterfeldes.
  • at least the FM but also the LMK radio signal should be capacitively coupled via a common decoupling element.
  • the per se known advantage can be maintained that both the LMK signal and the VHF signal is coupled out via this common capacitive decoupling element, whereby a non-negligible overall simplification of the antenna arrangement can continue to be realized.
  • the principle according to the invention can be improved in a particularly favorable and effective manner by further using so-called "crossing lines" known from the prior art, ie antenna conductors which are provided running perpendicular to the heating conductors and are galvanically connected to the heating conductors. These additionally provided antenna conductors extending at the equipotential points ensure that a resonant structure arises at the antenna connection point, in particular for the VHF frequencies.
  • the filter elements can be constructed with significantly less effort than in previous systems. This makes it possible to dispense with a separate investigation of the occurring mechanical stress of this assembly and the quality of the system over the vehicle life are ensured with unobtrusive filter assemblies.
  • the noise floor of the antenna for the LMK radio reception can be significantly reduced while maintaining filter elements for the LMK range.
  • the line structure is applied by conventional methods on a window pane, wherein it is irrelevant in the context of the invention, whether it is a window glass or laminated safety glass.
  • Said window is surrounded by a metallic frame and usually designed as a rear window of a motor vehicle.
  • the described arrangement can also be transferred to any other disc z. B. in ships.
  • the particular advantage of the invention is that either no special filter elements for decoupling the LMK antenna function of the electrical system disturbances in the form of a current-compensated ring choke (high-frequency technically high-resistance component) are necessary or the noise floor with LMK reception can be significantly reduced if filter elements for the LMK reception are maintained.
  • Another advantage of the embodiment of the invention is the cost-effective production. Over other Embodiments, only a single disc needs to be formed. Another advantage is the integrated and thus simple construction of passive or active circuit parts, which, although separate signal paths for the different frequency bands, but can be arranged in a single housing. This results in a minimum of mechanical components as well as minimal wiring.
  • FIG. 1 shows a glass antenna consisting of mutually parallel heating conductors 3, each open at their left and right ends in a busbar 4.
  • the Schuleiterfeld thus formed is each supplied via a FM / TV throttle 5 in the supply lines with heating (Ub heater).
  • an AM blocking circuit 13 with more or less complex filter effort or not.
  • the antenna connection point 1 for FM / TV and LMK signals is galvanically connected to a decoupling element 6 in Walkerleiterfeld but not with the Schuleiterfeld.
  • the decoupling element 6 can be used as a rectilinear conductor, as an open conductor loop as in FIG. 1 represented, or be designed as a closed conductor loop or combinations of the latter elements.
  • the decoupling element 6 is arranged in particular between two adjacent heating conductors 3 and extends parallel (legs of the open conductor loop) to the entire length of two heating 3.
  • the distance of the decoupling element 6 and its conductor pieces parallel to the heating conductors 3 should be as low as possible, so that capacitive coupling for FM / TV frequencies is ensured.
  • the ground point 9 for the connection of the active antenna assembly 7 is advantageously located in the immediate vicinity of the antenna connection point 1 in the upper right corner of the Schuleiterfeldes on the surrounding the window pane metallic frame 8 (shown in phantom).
  • the heat conductor structure of the disc is formed, for. B. by additional vertical crossing lines 10, which are connected at each intersection with the galvanic parallel heating conductors 3 and are on the forming by the voltage distribution equipotential points, that at the antenna connection point 1 for VHF frequencies, a resonant structure is formed.
  • the decoupled antenna signals are amplified separately (AM, FM, TV 1) and optionally filtered and supplied to the TV tuner 11 and radio 12.
  • FIG. 2 shows a further embodiment in which a further FM / TV antenna signal decoupling from the galvanically connected to the heating field on the opposite side antenna connection point 2 and a closely adjacent ground terminal is formed.
  • a two-antenna system is formed. It can be formed in the same place from the heating field at other locations even more antennas, z. For example, there are two more to generate a four-antenna system. It can be covered with another FM or TV area, a second VHF receiver to be operated or a diversity effect can be exploited by different received signals at the two antenna connection points 1 and 2, as he z. B. under unfavorable reception conditions in mobile use can come about.
  • the reception performance for FM / TV reception is comparable to known arrangements.
