Abstract: The radio antenna arrangement for establishing a radio link with terrestrial radio stations includes a group of antennas (10) mounted on an inclined window pane (1) of a particular electrically conductive motor vehicle body, each of the antennas (10) including an antenna element (3) mounted outside of an interior of the vehicle body (8) and on the window pane perpendicular to it; an antenna counterweight (4) mounted on the inclined window pane, the antennas (10) together forming a group antenna with a group antenna connection point (6); and a network (7) containing the group antenna connection point (6), the antennas being radiatively coupled to each other by high-frequency radiation and at least one antenna (10) having an antenna element connection point (2) connecting it with the network (7).

Abstract: The antenna diversity system for mobile reception of VHF and UHF waves has a plurality of antennae; an antenna distributor connected to each of the antennae to receive antenna signals from the antennae and having a plurality of inputs and sets of outputs; a plurality of antenna switches, each of the antenna switches being connected to one of the sets of outputs of the antenna distributor; a plurality of tuners, each of the tuners connected to one of the antenna switches and producing one of an intermediate-frequency signal and demodulated signal; a plurality of diversity processors, each of the diversity processors being connected to a tuner to receive an intermediate-frequency or demodulated signal therefrom and also to the antenna switch of the tuner connected thereto via a control line and being structured to carry out a signal evaluation of the signal received in the diversity processor to control the antenna switch to switch through a more favorable input signal to the tuner connected to it.

Abstract: Disclosed is a pane antenna installed in a heated window pane of a motor vehicle to receive frequencies above the high frequency range. The antenna includes at least one wire-shaped first antenna conductor extending across parallel heating conductors of a heating field. The crossing points of the first antenna conductor with heating conductors are preferably in galvanic contact to create a capacitive antenna region along the first antenna conductor. The capacitive antenna region is coupled via a second antenna conductor extending also perpendicularly to the heating conductors, to an antenna terminal arranged on the window pane in proximity to a rim. The window pane is surrounded by a conductive frame and a grounding point is created on the frame opposite the antenna terminal.
