Abstract
A receiver includes an array antenna, terminals, switches, a receiving circuit, a switch control unit and a reactance setting unit. Receiving circuit determines a received frequency and a received signal quality of a received signal by demodulating the received signal provided from the array antenna. The receiving circuit provides the received frequency to the reactance setting unit as a frequency setting signal, and provide the received signal quality to the switch control unit and the reactance setting unit. The reactance setting unit sets a set of the reactances corresponding to the received frequency in the terminals for each frequency, and the switch control unit switches connections in the switches to provide the received signal quality equal to or greater than the threshold.
