PROBLEM TO BE SOLVED: To provide an antenna matching technique effective for broadening the band. SOLUTION: The antenna matching circuit has a parallel resonator (3) connected to radiation elements (A, 33) forming an antenna. The parallel resonator (3) comprises a serial resonator composed of an inductance component (L) and a capacitance component (C), and the serial resonator realizes the matching of the antenna and the band broadening. The parallel resonator (3) may be inserted on a feeder line connected to the radiation elements or on a GND line connected to the radiation elements. COPYRIGHT: (C)2005,JPO&NCIPI
