Abstract

The invention discloses a satellite communication transceiving assembly and a two-dimensional active phased-array antenna. The phased-array antenna comprises a dual-polarized antenna array, a transceiving assembly with a double-radio frequency channel polarization adjusting function, a transceiving feed network, a control and power supply layer, a support framework, a heat dissipation device and a structure accessory. According to the invention, independent polarization adjusting technology of dual-polarization antenna unit in the transceiving assembly is carried out; received N paths of horizontal polarization signals and received N paths of vertical polarization signals are adjusted into N paths of signals through polarization adjustment, and are changed into one path of signal after being subjected to signal synthesis; control of amplitude and phase of polarization adjustment signals is facilitated; and a disadvantage of inappropriate control on the amplitude and phase of signal after the signal is synthesized is overcome. In the phased-array antenna, multiple modules are connected with each other without cables, so space size is effectively used; and a system adopts a phased-array technology to carry out space wave beam scanning, so rapid communication with a satellite system is achieved.

Description

technical field [0001] The technical fields involved in the present invention cover radar, communication, navigation, electronic warfare, reconnaissance, remote control and telemetry, etc., specifically a satellite communication transceiver component and a two-dimensional active phased array antenna. The invention is also particularly suitable for a satellite communication terminal phased array antenna system that performs functions such as fast capture, tracking, and polarization adjustment of satellite signals in time when satellite communication is carried out on a moving carrier. Background technique [0002] In satellite communications, the traditional antenna forms are reflector antennas and flat panel array antennas, which currently occupy most of the communication market. With the development needs of electronic information systems and the moving speed of moving carriers getting faster and faster, it has become a trend to install low-profile phased array antennas on ...
