Waveguide interface structure

Abstract

The embodiment of the invention relates to the field of microwave communication, and discloses a waveguide interface structure. The waveguide interface structure provided by the embodiment of the invention is used for electrically connecting a first waveguide and a second waveguide, and comprises an elastic electric connection part and a fixing part connected with the electric connection part, the fixing part is used for abutting against the end face of the first waveguide, and the electric connection part is enclosed to form an opening through which electromagnetic waves pass. And the electric connection part is elastically pressed between the end face of the first waveguide and the end face of the second waveguide and is electrically connected with the first waveguide and the second waveguide. The waveguide interface structure provided by the embodiment of the invention can reduce the processing difficulty of the waveguide structure on the premise of ensuring the normal signal transmission of the waveguide interconnection channel, and is suitable for the use scene of large-gap random tolerance.

Description

technical field [0001] The embodiment of the present invention relates to the field of microwave communication, and in particular to a waveguide interface structure. Background technique [0002] In the microwave frequency band, the waveguide has the smallest transmission loss, and it is an irreplaceable type of transmission line to improve the power generation and receiving sensitivity of the microwave communication system. When there is a gap in the waveguide interconnection, strong radiation loss and interference will occur, affecting the normal operation of the system. In the existing technology, most of the waveguide interconnection schemes are single waveguide ports and the priority is to ensure electrical connection, that is, the end faces of the two interconnected waveguide ports are in close contact. When there is a small interconnection gap, it is generally used around the waveguide port. The solution of placing the shielding sealing ring to solve the problem of e...
