PURPOSE: A dielectric resonator filter having a stable grounding structure is provided to maintain stable linear contact between a filter cover and a dielectric resonator using the restoring force of an elastic member. CONSTITUTION: A housing(100) protects internal components of a dielectric resonator filter from electromagnetic waves. The housing includes a plurality of cavities(110,112,114) in which dielectric resonators(120,122,124) are respectively installed. An input connector(104) receives RF signals through connection with a transmission line including RF cables. A cover(120) covers the opening of the housing by being bolted to the housing. |
