Waveguide antenna adapter for satellite wireless testing

Abstract

The invention provides a waveguide antenna adapter for satellite wireless testing. The waveguide antenna adapter comprises a polarization transmission waveguide, a waveguide assembly and a fixing device. The polarization transmission waveguide is of a waveguide type structure and transmits radio frequency wireless signals through the waveguide; the polarization transmission waveguide is provided with a first external interface and a second external interface; the first external interface is connected with a waveguide type antenna of a satellite; the size of the first external interface is matched and consistent with the size of a polarized waveguide port of the waveguide type antenna; and after the first external interface is connected with the polarization waveguide port of the waveguide type antenna, the polarization transmission waveguide shields an antenna radiator outside the polarization waveguide port of the waveguide type antenna. The polarization transmission waveguide has a polarizer function, and the polarization mode is the same as that of the waveguide type antenna; the waveguide assembly is used for connecting the polarization transmission waveguide with a ground test system; and the fixing device is used for connecting and fixing a waveguide antenna adapter and the waveguide type antenna on the satellite.

Description

technical field [0001] The invention relates to the technical field of satellite system ground wireless testing, in particular to a waveguide antenna adapter for satellite system ground wireless testing. Background technique [0002] In the development of satellite engineering, it is necessary to carry out satellite system-level wireless testing in the development stage. A ground antenna needs to be developed for sending and receiving communications with the antenna on the satellite. [0003] During the wireless test, due to the existence of electromagnetic wave radiation, on the one hand, the test will have an impact on the surrounding environment, causing certain harm to the on-site personnel, and the personnel need to leave the site during the test; on the other hand, during the wireless test, if there are many metal devices in the surrounding environment , will also have a certain impact on the accuracy of wireless testing. [0004] At present, when the known satellite...
