Document Type and Number:
WIPO Patent Application WO/2024/087011
Kind Code:

Abstract:
Embodiments of the present disclosure relate to a resonator and a filter. According to embodiments of the present disclosure, there is providing an improved resonator and an improved filter. A resonator comprises a housing that defines a cavity. The resonator also comprises a dielectric resonance element arranged inside the cavity. A first end of the dielectric resonance element is directly and conductively connected to the housing with a first fixing element. A second end of the dielectric resonance element is directly and conductively connected to the housing with a second fixing element. The first end is opposite to the second end. A filter comprises a housing, defining a cavity; a set of dielectric resonance elements, arranged in parallel and inside the cavity, wherein the set of dielectric resonance elements are directly and conductively connected to the housing; an input coupling element coupled with the set of dielectric resonance elements; an output coupling element coupled with the set of dielectric resonance elements; a cross-coupling element arranged between dielectric resonance elements in the set of dielectric resonance elements; and a tunning element for tunning a resonant frequency or a coupling between dielectric resonance elements in the filter. In this way, the structures of the resonator and the filter are simple and stable. Moreover, an improved Q value and a reduced size can be achieved.
