Problems solved by technology

[0003] The inventors of the present application found in long-term research and development work that the existing dielectric filter includes a dielectric body, a cover plate, screws and nuts. The plate is provided with a through hole corresponding to the blind hole, and the nut is arranged in the through hole, and the screw extends into the blind hole through the through hole. Since the dielectric filter needs to be provided with a cover plate on the dielectric body and the screws and nuts protruding from the cover plate, As a result, the thickness of the dielectric filter increases

Abstract

The invention discloses a dielectric filter, communication equipment, a dielectric resonator and a preparation method thereof. The dielectric resonator comprises: a dielectric body which is provided with at least one blind hole; a metal layer which covers the surface of the dielectric body; a first nut which is arranged in the blind hole; and a first adjusting screw rod which is arranged in the blind hole through a first nut, wherein materials of the dielectric resonator at least comprise strontium carbonate, samarium trioxide, aluminum oxide and titanium dioxide. The thickness of the dielectric resonator can be reduced, and then the size of the dielectric resonator is reduced.

Description

technical field [0001] The present application relates to the technical field of communication, and relates to a dielectric filter applied to a 5G communication system, a communication device, a dielectric resonator and a preparation method thereof. Background technique [0002] At present, wireless communication technology is developing rapidly, and wireless communication systems require high-performance dielectric filters. The main performance of dielectric filters is frequency selection and filtering. In the 5G communication system, since the number of transceiver channels has increased from 8 in the original 4G communication system to 64 or even 128, the dielectric filter of the 5G communication system has the characteristics of miniaturization and high performance. [0003] The inventors of the present application found in long-term research and development work that the existing dielectric filter includes a dielectric body, a cover plate, screws and nuts. The plate is...
