Abstract: A mobile antenna system features passive repeater operation to transfer energy between a radio transceiver located inside a vehicle and an external radiator mounted on the outside thereof. By this arrangement, a user of the radio transceiver can gain benefit from the external radiator without the hinderance of a physical, wired connection linking the transceiver to the antenna assembly. In a preferred embodiment, the antenna system operates without any electrical cable extending inside the vehicle from the external radiator.

Abstract: A mobile cellular antenna system includes an auxiliary antenna that is positioned inside the passenger compartment of a vehicle and is coupled to the radiator on the exterior of the vehicle. This arrangement permits users of portable or transportable cellular telephones with built-in antennas to gain transmission and reception advantage from the exterior antenna while operating from within the passenger compartment.

Abstract: The present invention is a moisture-insensitive system adapted to couple radio frequency energy at a low impedance from a matched two conductor transmission line, through a vehicle windshield and to an antenna in a manner which minimizes stray radio frequency radiation within the passenger compartment of the vehicle. The system includes two pair of conducting plates, one pair mounted on each side of the windshield, each pair opposite the other pair. A coaxial feed line is coupled to the inside pair of plates and a matching circuit is connected across the outside pair of plates. A full-size, unloaded antenna element is connected to the output of the matching circuit. A decoupling device, such as a decoupling sleeve or a RF choke, can be used to minimize RF current flow on the shield conductor of the coaxial feed line. The coaxial cable is coupled directly through the windshield, without an intervening matching network, so that RF energy at a low impedance is coupled to the outside pair of plates.
