<p>PROBLEM TO BE SOLVED: To provide an antenna matching circuit of simple configuration in which the variation range of impedance of the available antennas is wide, and to provide a control method therefor.SOLUTION: A matching section 11 of an antenna matching circuit includes a terminal P1 for connection with the antenna side, a terminal P2 for connection with the transmission and reception circuit side, a phase shifter PS1 and a variable capacitance element VC1. The phase shifter PS1 is connected in series between the terminals P1 and P2. The variable capacitance element VC1 is connected between the terminals P1 and P2.</p> |
