Abstract
In an antenna matching circuit including a parallel resonant section connected to a radiation element constituting an antenna, the parallel resonant section includes a series resonant portion composed of an inductance component and a capacitance component. The series resonant portion realizes antenna matching and band widening. The parallel resonant section can be inserted in a feeder line connected to the radiation element or inserted in a GND line connected to the radiation element.
