ABSTRACT:
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.
