Description

technical field [0001] The invention relates to the field of space-borne antennas, in particular to an X-band space-borne data transmission antenna. Background technique [0002] The digital transmission antenna is an important part of the satellite antenna. When the satellite enters the territory of the ground receiving station (that is, within the visible arc), the digital transmission subsystem takes out the data in the memory through the high-speed data interface, and the digital transmission transmitter completes the channel Coding to form a data transmission frame, after carrier modulation and power amplification of the signal, the data collected by the satellite payload is transmitted to the ground receiving station through the data transmission antenna. [0003] At present, satellites are developing toward low cost, miniaturization, light weight, and multiple satellites with one arrow, and the requirements for satellite antennas are bound to become higher and higher....
