Abstract
The present invention provides an automobile antenna system capable of receiving radio waves without need of an externally projecting part such as a pole type antenna externally exposed from the vehicle body, the automobile antenna system including a high-frequency pick-up disposed on the marginal portion of an engine hood or trunk lid on the vehicle body such that the length of the pick-up is parallel to the longitudinal axis of the engine marginal edge of the engine hood or trunk lid, whereby surface high-frequency currents induced on the vehicle body by radio waves and concentrically flowing on the marginal portion of the engine hood or trunk lid can be detected by the pick-up.
