Abstract
In order to perform feeding to an inverted F antenna having a plate conductor of an approximately rectangular shape for forming a radiation conductor and a ground conductor arranged in parallel with the place conductor, a strip conductor plate connected to a feeder line is provided on the ground conductor via a dielectric substrate. Hence, the feeding from the feeder line to the inverted F antenna 37 is performed by an electric field coupling of the plate conductor and the strip conductor plate. The inverted F antenna and a resonator are integrated by coupling means to carry out an impedance matching, and the inverted F antenna and the resonator 62 constitute a band pass filter.
