Problems solved by technology

However, phased array antennas are rarely used in mobile satellite communication systems
[0003] The existing antennas used in mobile satellite communication systems are mainly reflector antennas, which are large in size and heavy in weight and are not easy to install
Moreover, this form of antenna scanning method can only be two-dimensional mechanical scanning, and the speed is slow, which is difficult to meet the requirements of mobile satellite communication for antenna tracking performance in specific occasions.

Abstract

The invention discloses a phased array mobile satellite receiving antenna with plane structure, relating to a high-efficiency communication signal receiving device in a mobile satellite communication system. The antenna comprises a receiving antenna array, a feed network, a tracking and receiving system, a servocontrol system, a wave beam control system and an antenna pedestal. The invention adopts the tracking mode of combining two-dimensional phased array electric scanning and tracking with two-dimensional mechanical tracking to realize quick satellite searching and unremitting satellite signal tracking and receiving. The invention has the characteristics of high efficiency, low outline, high searching speed, high tracking precision, unremitting satellite signal receiving and the like, and is especially favourable for designing and manufacturing the ground mobile receiving antenna of high-performance satellite communication in the mobile satellite communication system.

Description

technical field [0001] The invention relates to a high-efficiency communication signal receiving device in a mobile satellite communication system, and is especially suitable for the design and manufacture of a high-performance phased array ground mobile satellite receiving antenna in the mobile satellite communication system. Background technique [0002] The phased array antenna has the characteristics of fast switching antenna beam pointing, which overcomes the shortcomings of large inertia and slow speed when the antenna is mechanically rotated. Phased array technology has been used in various military radars, including various airborne and spaceborne synthetic aperture radars, and a variety of military and civilian dual-use and civilian radars, including high-performance weather radars and space-borne weather detection radars. However, phased array antennas are rarely used in mobile satellite communication systems. [0003] The existing antennas used in mobile satellit...
