ABSTRACT:
A dielectric block having an external conductor on the outer surface and a plurality of holes with internal conductors formed therein; no internal conductors are provided near one end of each of the plurality of holes. Portions of the dielectric block and the external conductor are removed so as to obtain a dielectric resonator having desired resonator characteristics. In another embodiment, portions of the dielectric block are removed so as to bring the external conductor closer to the internal conductors thereby obtaining a dielectric resonator resonant with a desired frequency. The dielectric resonators limit leakage of electromagnetic field and do not require additional parts such as terminals and case.
