Title:
HYBRID RESONANCE STRUCTURE INCLUDING CAVITY AND METAL/DIELECTRIC ROD, AND FILTER
Document Type and Number:
WIPO Patent Application WO/2019/119658
Kind Code:
A1
Abstract:
Disclosed in the present invention are a hybrid resonance structure having a cavity and a metal/dielectric rod, and a filter. The structure comprises a metal single cavity and a dielectric resonance rod disposed in the metal single cavity. The dielectric resonance rod comprises a coaxially disposed middle metal resonance unit and end portion dielectric resonance units. At least one end portion dielectric resonance unit is disposed at each of two ends of the middle metal resonance unit. The present invention has a simple structure and is convenient to install and use. The dielectric resonance rod has a segmented structure. The middle metal resonance unit is made of a metal material and the end portion resonance units are made of a dielectric material. A coaxial metal cavity is added compared to existing traditional cavity filters, such that the height of a filter having the structure of the present invention can be reduced by more than 1/3 compared to that of a filter in the prior art, effectively reducing the frequency of the filter without increasing volume.
