发明名称 DIELECTRIC RESONANCE FILTER
摘要 PROBLEM TO BE SOLVED: To miniaturize a filter by using the corner part of the metallic cavity of a rectangular parallelopiped and fitting a probe so that two faces forming the corner part of a square metallic cavity are short-circuited. SOLUTION: One dielectric resonator 1 and input/output probes 2 and 3 are installed in a metallic cavity constituted of a metallic case 5 and a metallic cover 6 through a support stand 11 on the metallic case 5. The input/output probes 2 and 3 are connected to one dielectric resonator 1 and they are connected to input/output connectors 7 and 8 which are protrusively installed to an outer side at the vicinity of the corner parts of the metallic case 5. One end of the input probe 2 is connected to the input connector 7 and the other end is short-circuited to one other face near a corner where the input connectors 7 and 8 are not installed in the two faces of the metallic case 5. A copper wire being the input probe 2 is straight and a distance between the dielectric resonator 1 and the input probe 2 is about 3 mm.
