ABSTRACT:
A dielectric resonator comprises a shield electrode defining a resonant space and cylindrical dielectric resonator element disposed and supported fixedly in the resonant space, to which an input and output are coupled. Into the hollow portion of the dielectric resonator element, a tuning unit made of a dielectric material is inserted so as to be displaceable in an axial direction therein. The tuning unit is coupled to a supporting axis which is displaceable axially, thus causing the tuning unit to displace in that direction. A resonance frequency of the dielectric resonator varies as the tuning unit displaces.
