Title:
THREE-MODE DIELECTRIC RESONATOR AND DIELECTRIC FILTER
Document Type and Number:
WIPO Patent Application WO/2024/046276
Kind Code:
A1
Abstract:
The present application relates to the technical field of communications. Provided are a three-mode dielectric resonator and a dielectric filter. A dielectric body of the three-mode dielectric resonator is provided with a first resonant blind hole, a second resonant blind hole and a third resonant blind hole, wherein the first resonant blind hole, the second resonant blind hole and the third resonant blind hole are respectively used for forming a first resonant mode, a second resonant mode and a third resonant mode; and the first resonant mode, the second resonant mode and the third resonant mode are all quasi-TEM modes. The three-mode dielectric resonator provided in the present application can effectively improve the space utilization rate of a dielectric resonant cavity, reduce the size and the weight of a dielectric filter, and can improve out-of-band rejection performance.
