PROBLEM TO BE SOLVED: To provide a favorable communication state by flexibly changing an antenna configuration.SOLUTION: A physical distance between a plurality of antennas, and a polarization direction of a signal transmitted and received by each of the antennas are specified as a physical configuration of the antennas, and a combination of antennas to be used is selected on the basis of the specified result. Alternatively, a reception quality is detected for each combination of antennas of a plurality of types, and a combination of antennas to be used is selected in accordance with a comparison result of the detected reception quality. When a plurality of signal processing circuits for processing signals to be transmitted and received are provided so as to correspond to the plurality of antennas, power supply to a circuit that is not used is stopped on the basis of the combination of the selected antennas. Alternatively, a setting value for performing communications between a specific communication target or another communication target is acquired using an antenna that is not selected and a signal processing circuit associated with the antenna. |
