Patent ID: 8106838

Claim:
A mobile wireless communications device, comprising: a portable handheld housing; a circuit board carried by the portable handheld housing and RF circuitry carried by the circuit board; a diversity antenna and main antenna carried by the portable handheld housing and coupled in a connection to the RF circuitry and operative together wherein the RF circuitry tunes the diversity antenna into diversity communications frequency band to achieve a diversity mode of operation with the main antenna and tunes the diversity antenna into a non-diversity communications frequency band when cross-coupling has occurred from the diversity antenna to the main antenna when operating in the diversity communications frequency band; and a switch carried by the portable handheld housing and connected to the RF circuitry and coupled between the diversity and main antennae that disconnects the diversity antenna in a non-diversity communications frequency band, wherein the connection becomes open circuit in the non-diversity communications frequency band.
