ABSTRACT:
An automobile antenna system is composed of a windshield antenna provided on a windshield of a vehicle body, and a pair of high-frequency pickups provided at a portion of a vehicle body which is remoted from the windshield, at both ends thereof. The output of the windshield antenna and the output obtained by adding the outputs of the high-frequency pickups together are selectively fetched by a diversity reception circuit in accordance with the reception sensitivity of each antenna, whereby space diversity reception is enabled. The high-frequency pickups are secured to a roof panel, a trunk lid, front pillars, or the like, in order to detect the surface currents induced on the vehicle body by broadcast waves and flowing at the marginal portions of the vehicle body.
