    • A mobile wireless communications device has a portable handheld housing. A circuit board is carried by the portable handheld housing. RF circuitry is carried by the circuit board. A diversity antenna and main antenna are carried by the portable handheld housing and coupled to the RF circuitry and operative together. The RF circuitry tunes the diversity antenna into a 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. A switch is carried by the portable handheld housing and connected to the RF circuitry and coupled between the diversity and main antennae and disconnects the diversity antenna when operating in the non-diversity band to prevent cross-coupling from the diversity antenna to the main antenna.
    • 移动无线通信设备具有便携式手持式外壳。 电路板由便携式手持式外壳承载。 RF电路由电路板承载。 分集天线和主天线由便携式手持外壳承载并耦合到RF电路并一起操作。 RF电路将分集天线调谐为分集通信频带,以实现主天线的分集模式,并将分集天线调谐为非分集通信频带,当从分集天线到主分路时发生交叉耦合 天线在分集通信频段工作时。 开关由便携式手持式外壳承载并连接到RF电路并且耦合在分集和主天线之间,并且在非分集频带中操作时断开分集天线,以防止从分集天线到主天线的交叉耦合。
