| Abstract | A mobile wireless communications device may include a portable housing, and an antenna carried by the portable housing. The mobile wireless communications device may further include wireless communications circuitry carried by the portable housing and an adjustable impedance matching network coupled between the wireless communications circuitry and the antenna. An audio input transducer and an audio output transducer may be carried by the portable housing. The mobile wireless communications device may further include a controller carried by the portable housing and configured to determine an acoustic coupling between the audio input transducer and the audio output transducer. The controller may further be configured to adjust the adjustable impedance matching network based upon the determined acoustic coupling. |
