Abstract
A planar, compact, multiple-element directive antenna for a hand-held radio frequency transceiver, such as a cellular telephone or PCS device, is provided which has an active radiating conductor element, a dielectric spacing member, and a conductive ground plane. The operative conductive round plane may be provided solely by an existing one internal with the hand-held transceiver, such as a printed wiring board, a metal chassis, or a metallized plastic surface, or by a parallel small ground plane coupled capacitively or directly to the larger transceiver ground plane. The multiple-element directive antenna allows increased range, improved voice/data quality, increased battery life, reduced user exposure to radio frequency radiation, elimination of user antenna adjustments, and reduction of antenna susceptibility to damage.
