Abstract
A mobile communication device is provided having a peripheral metal bezel made up of a plurality of metal segments. At least one of the metal segments on the bezel is configured to be a main antenna that is connected to a transceiver circuit via an antenna matching circuit. Proximate to the main antenna is another metal segment on the metal bezel that is configured to be a capacitance proximity sensor. The capacitance proximity sensor, in conjunction with a capacitance sensing circuit provide information to the circuitry within the mobile communication device to tune the antenna matching circuit to impedance match the transceiver with the antenna.
