Abstract

See full text

An automatic matching circuit includes a variable inductor disposed in order to perform impedance matching at a high frequency equal to or higher than 2 MHz between the output. impedance of a resonant type reception antenna 10 and the input impedance of a high frequency rectification circuit 11, to cause an inductance value to be variable by using an electronic part that electrically performs contact switching including continuous contact switching, a variable capacitor disposed in order to perform the impedance matching, to cause a capacitance value to be variable by using an electronic part that electrically performs contact switching including continuous contact switching, and a variable control circuit 1 to control the electronic parts, in the variable inductor and the variable capacitor, each of which electrically performs the contact switching including the continuous contact switching, in such a way as to perform the impedance matching.
