Abstract (en)

A resonator having a defected ground structure (DGS) coupling an electronic element at the position of a gap in a DGS cell formed on a ground plane of a dielectric substrate is provided, to thereby control the Q factor and the resonant frequency of the resonator smoothly. The resonator includes a dielectric substrate formed of a dielectric material, a ground plane having an etched portion including a gap forming an electric field density portion on either inner side, with a conductive film coated on one surface of the dielectric substrate, a transmission line coated at the gap position on the surface opposing the ground plane on the dielectric substrate, to thereby transmit a signal, and an electronic element whose either end is connected with either end of the ground plane. <IMAGE>
