Abstract:
A system that incorporates teachings of the subject disclosure may include, for example, an antenna system coupled with the transceiver that includes a first antenna and a second antenna where one of the first or second antennas is operating as a primary antenna and the other of the first or second antennas is operating as a diversity antenna. The system can include an RF switch connected with the antenna system, where the RF switch has a first position in which the first antenna is the primary antenna and the second antenna is the diversity antenna, and wherein the RF switch has a second position in which the second antenna is the primary antenna and the first antenna is the diversity antenna. The system can include a controller coupled with the matching network and with the RF switch, where the controller receives first reflection measurements associated with the antenna system, and where the controller adjusts the RF switch to select between the first and second positions according to the first reflection measurements.
