Antenna system incorporated in the air spoiler of an automobile
 An antenna system for use in an automotive vehicle comprises a housing mounted on a body of the automotive vehicle and having at least a portion of an upper surface thereof made of a dielectric material which transmits radio waves, at least one planar antenna disposed rotatably within the housing to receive radio waves transmitted through the portion of the upper surface of the housing made of the dielectric material, and driving means for driving the planar antenna to effect scanning of a radio wave receiving direction to search for the radio wave receiving direction of higher sensitivity. The housing protects the antenna system and maintains the fine appearance of the automotive vehicle. Further, the housing has a shape like that of an air spoiler, which makes it possible to maintain the satisfactory aerodynamic characteristic of the automotive vehicle.
