    • The present invention provides a vehicle antenna system embedded in the vehicle body for efficiently detecting external waves and transmitting the detected signals to an onboard receiver. The antenna system includes a metallic armor member arranged extending along the vehicle body and electrically insulated from the vehicle frame and an antenna element disposed in close proximity to the metallic armor member without outwardly extending from the vehicle body. The metallic armor member is preferably a side molding on the vehicle body. The antenna element is in the form of an antenna wire or loop antenna disposed extending along the length of the side molding. The antenna element is intersected by an alternating field created by the surface currents on the metallic armor member to generate high frequency currents in the antenna element, the generated currents being then transmitted directly to the onboard receiver through a cable.

    • An automobile antenna system which requires no pole antenna or the like projecting outwardly from the automobile body includes a high-frequency pickup, for example, comprising a loop antenna, which is incorporated within a portion of the vehicle body. The high-frequency pickup is secured to the rear window frame and the longitudinal side of the loop antenna which is partially exposed through the casing of the high-frequency pickup is disposed in the vicinity of an edge-moulding mounting retainer. The loop antenna picks up high-frequency surface currents which are caused by broadcast waves and which concentratively flow in the edge-moulding mounting retainer.

    • The present invention provides an autombile antenna system for detecting surface currents induced on the vehicle body by radio waves. The antenna system includes an electrostatic shielding case mounted on the vehicle body and having an opening formed therein. The opening in the case faces a metallic plate in the vehicle body and a loop antenna is housed within the case and disposed in close proximity to the opening thereof. The loop antenna has a plane of the loop positioned relative to the surface of the metallic vehicle plate at an angle in the range of 90 degrees to 135 degrees or 225 degrees to 270 degrees, whereby the antenna system can more efficiently detect the surface currents induced on the vehicle body by radio waves and can be miniaturized and improved in performance without any externally protruding member.
