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). The network (7) is designed to provide a permanently set phase and amplitude relationship for base point feed currents fed to the respective antenna elements (3) depending on the particular motor vehicle body, their values set at least partially by electrical connections to and within the network (7) and, optionally, by loading terminal pairs (27) associated with the antenna element connecti…
