Impedance converting circuit and communication terminal apparatus
An impedance converting circuit module includes a first matching circuit, a feeding-circuit-side matching circuit interposed between the first matching circuit and a feeding circuit, and an antenna-side matching circuit interposed between the first matching circuit and a radiating element. The feeding-circuit-side matching circuit performs impedance matching between a feeding port of the feeding circuit and the first matching circuit, and the antenna-side matching circuit performs impedance matching between a port of the radiating element and the first matching circuit.
