ABSTRACT:
The present invention provides an automobile antenna system including a high-frequency pick-up device for receiving broadcast waves and which includes a loop antenna or detection electrode element disposed parallel and in close proximity to the marginal edge of the vehicle body and spaced from the marginal edge of the vehicle body within a range represented by 12.times.10.sup.-3 .lambda.(m) where .lambda. is the wavelength of a given broadcast wave measured metric units, to detect surface high-frequency currents on the marginal portion of the vehicle body. The high-frequency pick-up device is connected with a varactor diode to adjust the resonance frequency of the antenna system. The tuned frequency of a receiver is used to vary a voltage applied to the cathode of the varactor diode such that the frequency of the antenna system will coincide with the tuned frequency of the receiver.
