Title:
DIELECTRIC RESONATOR AND FILTER
Document Type and Number:
WIPO Patent Application WO/2019/095103
Kind Code:
A1
Abstract:
The present application provides a dielectric resonator, comprising a dielectric body disposed in a hollow conductive housing. The dielectric body comprises a first end surface and a second end surface arranged opposite to each other as well as a circumferential surface connected between the first end surface and the second end surface; the first end surface is provided with a first groove, and the second end surface is provided with a second groove; the first end surface and the second end surface contact the inner wall of the conductive housing; the first groove and the second groove extend in different directions. The present application also provides a filter. The present application can implement single-sided mounting of the dielectric resonator so that the goal of miniaturization is achieved and assembly becomes easy. Moreover, the coupling between different resonance modes can be enhanced because the first groove and the second groove extend in different directions.
