Title:
ALL-DIELECTRIC HYBRID RESONANCE STRUCTURE AND FILTER
Document Type and Number:
WIPO Patent Application WO/2019/119657
Kind Code:
A1
Abstract:
Disclosed in the present invention are an all-dielectric hybrid resonance structure and a filter. The structure comprises a single cavity block and a dielectric resonance rod disposed in the single cavity block. The single cavity block is an all-dielectric single cavity block. The dielectric resonance rod comprises a coaxially disposed middle resonance unit and end portion resonance units. At least one end portion resonance unit is disposed at each of two ends of the middle resonance unit. The dielectric constant of the middle resonance unit is greater than that of the end portion resonance unit and that of the all-dielectric single cavity block. The present invention has a simple structure and can meet the requirements of a cavity dielectric filter for a higher Q value and smaller volume.
