Abstract
In a cavity body, a conductor rod is provided with least one end thereof being electrically connected to the cavity. A dielectric core is disposed in the cavity and the conductor rod extends through a hole in the dielectric core. With this structure, the cavity and the conductor rod constitute a resonator which operates in the quasi-TEM mode of a re-entrant cylindrical cavity resonator. The cavity and the dielectric core constitute a resonator which operates in the quasi-TM mode.
