ABSTRACT:
A coil electrode pattern is disposed on one surface of a plate consisting of a dielectric material. The coil electrode pattern is formed in a loop shape. An input/output terminal pattern and an earth terminal pattern are drawn out from the coil electrode pattern toward an end portion of the plate. The input/output terminal pattern and the earth terminal pattern are disposed at a distance from each other so as to provide a predetermined impedance. An earth electrode pattern is formed opposite the dielectric coil electrode pattern with the plate between them. An earth terminal pattern is formed to the earth electrode pattern. The earth terminal pattern of the earth electrode pattern is connected to the earth terminal pattern of the coil electrode pattern. A trimming electrode may be formed for adjusting the resonance frequency of the resonator optionally.
