Abstract
The present invention provides a vehicle antenna system including high frequency pickup type antennas concealed within the vehicle body for receiving broadcast waves. The high frequency pickups are arranged on the vehicle body at locations spaced apart from one another, that is, at least one adjacent to the vehicle roof and the other on a trunk hinge. The antenna system also includes a diversity circuit for automatically selecting one of the high frequency pickups which is in its optimum state of reception. Each of the high frequency pickups is disposed near the marginal portion of the vehicle body such that surface high frequency currents concentratedly induced on the marginal portion of the vehicle body can be detected by the high frequency pickup. Each of the high frequency pickups includes a loop antenna or electrostatic electrode disposed near the marginal portion of the vehicle body.
