Abstract

See full text

A wireless communication device such as a cellular telephone handset is disclosed including a housing having a transceiver circuit disposed therein. An internal antenna is also disposed within the housing which is RF connected to the transceiver circuit. An external, retractable antenna is mounted on the housing and is selectively movable between a retracted position and an extended position. The external, retractable antenna is RF connected to the transceiver circuit. When the external antenna is retracted, the internal antenna functions as a primary antenna. Should the need arise, the external antenna may be extended to improve the quality of the radio signals.
