Abstract
Apparatus is provided for coupling to a hand-held transceiver such as a cellular phone that is being operated in a radio frequency-shielded environment such as in an automobile, to transfer energy between the transceiver and an auxiliary antenna that is not shielded from the surroundings. The apparatus includes a pair of capacitor coupling elements (30, 32) that are positioned adjacent to each of the two radiating elements (40, 54) of the hand-held transceiver, and a coaxial cable (20) that connects the coupling elements to the auxiliary antenna. Each coupling element includes a sheet of electrically conductive material lying adjacent to a corresponding radiating element of the transceiver without surrounding the transceiver. A piece of releasable fastening material such as VELCRO is fixed to the transceiver, and a corresponding releasable fastening piece is fixed to the coupler that includes the coupling elements, to enable the user to quickly mount the coupling to transmit and receive from within a vehicle and to quickly disconnect for use of the transceiver outside the vehicle.
