ABSTRACT:
One or more antenna elements are submerged beneath a faired cover over a roof supporting member of a motor vehicle or hidden behind or as part of the front grill. Usually a conductive support extends behind the antenna elements and are electrically isolated therefrom to form the ground plane of the antenna. In some cases the antennas can be the structural members electrically isolated from the remainder of the body, but physically connected thereto. RF absorbers may be positioned spaced from radiating antenna elements to prevent antenna cross talk and exposure of occupants of the vehicle to high RF power densities. The antenna elements are especially useful in providing collision avoidance radar.
