Title:
MIXED DIELECTRIC CAVITY RESONANCE STRUCTURE FOR FILTER, AND FILTER
Document Type and Number:
WIPO Patent Application WO/2019/114141
Kind Code:
A1
Abstract:
Disclosed in the present invention are a mixed dielectric cavity resonance structure for a filter, and a filter, the structure comprising a filter and a dielectric resonance rod disposed in the filter cavity, wherein the dielectric resonance rod comprises an intermediate resonance unit and end resonance units which are coaxially arranged; at least one of the end resonance units is arranged at each end of the intermediate resonance unit; and the dielectric constant of the intermediate resonance unit is greater than that of the end resonance units. The present invention not only has a simple structure, but also meets the requirements for a cavity dielectric filter to have a greater Q value and to be smaller in volume.
