Anti-burnout and anti-jamming antenna equipment

Abstract

The present invention provides an anti-burnout and anti-jamming antenna device, comprising: an antenna radiating unit used to receive electromagnetic wave signals from space; a 3dB 90° electric bridge electrically connected to the antenna radiating unit for The electromagnetic wave signal is synthesized into a left-handed signal and a right-handed signal; a bandpass cavity filter is used to filter out out-of-band interference signals in the left-handed signal and the right-handed signal; a receiving link is used to receive and Processing the left-handed signal and right-handed signal filtered by the band-pass cavity filter, and sending the processed left-handed signal and right-handed signal to the radio frequency front end. The anti-burnout and anti-interference antenna device provided by the present invention increases the anti-burnout power level, improves the anti-burnout capability of the antenna device, and combines the characteristics of the cavity filter on the antenna device, so that the antenna device has frequency selectivity, Effectively suppress and filter out useless and interfering signals and clutter, increasing the anti-jamming ability of Tianjie equipment.

Description

technical field [0001] The invention relates to the field of satellite communication, in particular to an anti-burnout and anti-jamming antenna device. Background technique [0002] At present, satellite communication is still mainly overseas, such as international maritime satellites and iridium satellites. The application scenarios are often in places where the ground network cannot cover, and are widely used in the field of marine fishery. In the early morning of August 6, 2016, "Tiantong-1 01 Satellite" was successfully launched, which is also the first satellite of my country's satellite mobile communication system, breaking the status quo of relying on foreign satellite mobile communication services. On March 22, 2018, the Tiantong-1 mobile communication satellite system was officially put into use. Tiantong-1 satellite phone service types include voice, short message, fax, data, video, etc., and the service rate is 1.2kbps~384kbps. In terms of usage, users can use t...
