Definitions

  • Another disadvantage of this prior art antenna is the large interference coupling into the receiver input, especially at low frequencies. These high-frequency interferences are caused by the electrical units in the vehicle, such as by ignition and injection pulses. Since in an antenna according to DE-PS 26 50 044 the antenna element is connected both to the receiver input and, when the rear window heating is switched on, to the high-frequency disturbed DC voltage supply, screening measures in the DC voltage supply are highly effective, particularly for the low-frequency LMK, to avoid reception interference - Area required. The technical effort for this screening is partly due to the high heating - currents (up to approx. 30 A) considerably.
  • an antenna conductor 3 which is not galvanically connected to the heating field 2 and has a flat design, for receiving the LMK signals, which is arranged in the area of the rear window 1 which is not covered by the heating field, and whose connection 4 to the Input terminal 5 of a low-noise linear LMK amplifier 6 with a capacitively high-impedance input resistor is connected to the total input capacitance Cv in the antenna amplifier 23 via a lead that is as short as possible and the ground connection 22 of the antenna amplifier is connected as short as possible to the conductive edge of the rear window and the distances of this antenna lead are dimensioned with the transverse dimensions b from the edge of the disk and from the heating field so that the amplifier input signal is maximum and the output signal of the LMK amplifier 6 is fed to the first input 10 of a crossover 11 in the antenna amplifier 23 and the antenna connection point 12 dur ch the output of this crossover is formed and in the antenna amplifier 23 there is a separate signal path) 13 for VHF signals
  • the resulting signal-to-noise ratio is E / Eg and can be represented as follows:
  • the distance between the heating field 2 and the pane edge 1 is too small to cause a sufficiently small minimum field strength (FIG. 12).
  • a reduction in the width h of the free stripe from 20 cm to 6 cm with optimal dimensioning according to the invention leads to a signal-to-noise ratio in the LMK range which is about 10.5 dB worse.
  • an improvement in the limit sensitivity can be achieved if the heating field 2 is also insulated from the direct current supply 26, 27 with high frequency in the LMK range, as can be done, for example, with the aid of a bifilar throttle 30 according to FIG. 8.
  • the heating field 2 carries an LMK-frequency signal voltage with respect to the body surrounding it.
