AI Technical Summary

Problems solved by technology

The upper surface of the entire dielectric resonant column is not completely in contact with the cover plate, which increases the contact resistance, thereby increasing the loss and affecting the performance index of the filter
Moreover, the added small cover plate 201 increases the volume of the entire dielectric filter, which not only has a complex structure but also takes up a large space, resulting in waste of materials

Abstract

The embodiment of the invention provide a medium resonator and its assembling method and medium filter. The medium resonator comprises a medium resonance column and metal cavity; The medium resonance column is positioned in the metal cavity; bottom of the medium resonance column contacts bottom of metal cavity; The medium resonance column also comprises: a cover board and conductive elastic body; the cover board is positioned at upper surface of the metal cavity for sealing the metal cavity; the conductive elastic body is positioned between the cover board and the medium resonance column for facilitating contact of the cover board and the medium resonance column. The medium filter of the embodiment guarantees good contact of cover board and medium resonance column by resiliency of pressurized conductive elastic body, and incontinuous transmission of electric current, thereby effectively preventing electric current leakage, promoting filter performance of medium filter, and reducing size of whole size of medium resonator due to sealed contact.

Description

Technical field [0001] The present invention relates to the technical field of network communication, in particular to a dielectric resonator, an assembly method thereof, and a dielectric filter. Background technique [0002] When propagating in a material with a high dielectric constant, the wavelength of the electromagnetic wave can be shortened, so the use of a dielectric filter can reduce the size of the filter. The filter is a very important component in the base station products, so the dielectric filter is of great significance to the miniaturization of the base station products. [0003] See figure 1 , The picture is a schematic diagram of a TM (transverse magnetic) mode dielectric filter, which is mainly composed of a dielectric resonant column and a metal cavity. [0004] According to the principle of electromagnetics, when the resonator is working normally, there is a current distribution at the connection between the upper and lower end faces of the dielectric resona...
