Problems solved by technology

[0003] In the prior art, the reflective surface and the feed source of the microwave antenna are usually connected together by a single connector such as a screw, so there must be a gap between the feed source and the reflective surface
In the low-frequency field, this gap will not have a great impact on the performance of the antenna, but in the high-frequency microwave field, this gap will cause a large amount of leakage of electromagnetic waves and affect the overall performance of the antenna

Abstract

The invention relates to a microwave antenna subsystem which comprises a metal reflecting surface and a feed source, wherein a port of the feed source for transmitting or receiving electromagnetic waves is corresponding to a through hole at the bottom of the metal reflecting surface. The microwave antenna subsystem also comprises a seal ring arranged between the metal reflecting surface and the feed source, the seal ring seals the metal reflecting surface and the feed source and prevents electromagnetic leakages, and the seal ring is placed in a groove formed from the metal reflecting surface and the feed source and is fixedly connected with the metal reflecting surface, the feed source and the seal ring. With the seal ring, electromagnetic leakages of an antenna during high-frequency microwave communication can be effectively prevented, electromagnetic loss is reduced, and antenna performance is increased.

Description

technical field [0001] The present invention relates to an antenna sub-antenna, in particular to a microwave antenna sub-system. Background technique [0002] The microwave antenna is an important part of the microwave relay communication system. It mainly includes a parabolic reflector and a feed source. The feed source is located on the lower side of the reflector to transmit or receive electromagnetic waves. The electromagnetic waves emitted from the feed source are reflected by the reflective surface to be emitted to the outer space, and the electromagnetic waves emitted from the outer space are also converged to the feed source through the reflective surface. [0003] In the prior art, the reflective surface and the feed source of the microwave antenna are generally connected together through a single connecting piece such as a screw, so there must be a gap between the feed source and the reflective surface. In the low-frequency field, this gap will not have a great im...
