A mobile wireless communications device may include a plurality of antennas, a plurality of wireless transceivers, and signal processing circuitry. The device may further include a controller for selectively switching the signal processing circuitry to a desired one of the wireless transceivers, and for selectively switching a desired one of the antennas to the desired one of the wireless transceivers. Moreover, the controller may also be for selectively connecting and disconnecting the at least one other one of the antennas to an unused one of the wireless transceivers.

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.
