Title:
TM MODE DIELECTRIC FILTER, AND COMMUNICATION RADIO FREQUENCY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/113222
Kind Code:
A1
Abstract:
The present invention provides a TM mode dielectric filter and a communication radio frequency device. The TM mode dielectric filter comprises a cavity, a cover plate, and at least two dielectric resonators provided in the cavity. The cover plate covers the cavity, the dielectric resonators are separated by a partition wall to form respective resonant cavities, the partition wall between at least two adjacent resonant cavities is provided with a coupling slot, and the coupling slot is provided with a coupling. The coupling comprises a first coupling portion, a second coupling portion, and a connection portion. Both ends of the connection portion are respectively connected to the first coupling portion and the second coupling portion, the connection portion passes through the coupling slot, and the first coupling portion and the second coupling portion are disposed respectively in the adjacent resonant cavities. The first coupling portion and the second coupling portion both have a ring structure, a plane where the ring structures are located is parallel to an electric field direction of the dielectric resonators, and the ring structure of both the first coupling portion and the second coupling portion is provided with a gap interrupting the ring structure. The TM mode dielectric filter of the invention can establish capacitive coupling and transfer stronger electric field energy.
