Dielectric resonator device having resonator electrodes with gaps, and method of manufacturing the same

摘要

A dielectric resonator device in which resonant electrodes are provided in or on a dielectric block, and another ground electrode is formed on an outer face of the dielectric block. Lengths of the resonant electrodes are determined according to desired resonance frequencies of the respective resonators, while widths of regions having no electrodes are determined according to the desired amounts of coupling between the respective resonators. Since the dielectric block may be standardized, various kinds of dielectric resonator devices having different characteristics can be obtained without increasing the required number of kinds of molding metal molds.
