Multi-mode integrated satellite antenna with dynamically adjustable gain

Abstract

The invention provides a multi-mode integrated satellite antenna with dynamically adjustable gain. The multi-mode integrated satellite antenna comprises an antenna array, a broadband radio frequency switch, a control module and a multi-channel satellite communication module. The antenna array works in an S frequency band, and the antenna array comprises a plurality of antenna units; the antenna array is connected with the multi-channel satellite communication module through the broadband radio frequency switch to form a feed network; the plurality of antenna units work in different communication modes; and the control module constructs an objective function by adopting a minimum-maximum proportional fairness principle, controls a broadband radio frequency switch through an antenna transmit-receive gain dynamic control algorithm, selects to switch different communication modes or is in a closed state, and realizes the transmit-receive gain dynamic adjustment of multiple satellite communication modes. According to the invention, a multi-mode concurrent satellite communication function can be realized, adjustable transmitting and receiving gains in various communication modes are supported, and the overall structure size of the multi-mode antenna is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of satellite antennas, in particular to a multi-mode integrated satellite antenna with dynamically adjustable gain.
