Abstract
A dielectric resonator structure includes a resonator made of a dielectric material. The resonator is supported between two support plates and can be displaced at least in one direction between the plates. At least one of the plates is made of a dielectric material so that the amount of the dielectric material of the support plate varies in the direction of displacement of the resonator.
Claims12
A dielectric resonator structure, comprising:
- a resonator made of a dielectric material;
- a pair of two spaced apart but confronting support plates, said resonator being supported between said plates;
- means for displacing said resonator between said support plates, in at least one direction that is parallel to said support plates;
- at least one of said support plates being made of a dielectric material and having an opening provided therethrough, the width of said opening crosswise of said direction varying in said direction if relative to said resonator as a result of said resonator being displaced in said direction by said means for displacing.
