ABSTRACT:
An automobile antenna system for receiving broadcast waves by means of a plurality of antennas, which are provided on a vehicle body, outputs the receiving signal from the antenna which enjoys the optimum reception by automatic changeover. The antenna system includes a pair of glass antennas disposed on the rear window or side windows of the vehicle body and a pair of high-frequency pickups disposed on both sides of the vehicle body apart from the glass antennas by a predetermined distance for effectively picking up high-frequency surface currents which are induced on a vehicle body by broadcast waves, these four antennas constituting a diversity antenna.
