Problems solved by technology

[0003] 1. Reflector antenna is the main form of satellite communication antenna at present, but its structure is large and heavy, which is not easy to install
Since the reflector antenna needs two-dimensional mechanical tracking, its tracking speed is slow under the conditions of mobile satellite communication, and it is difficult to guarantee the tracking performance
[0004] 2. Low-profile multi-group array antenna adopts multi-group array method to achieve low profile, and phase adjustment can be performed between each group of arrays, but the main disadvantages are: low antenna efficiency, poor electrical performance; slow tracking speed; after a long period of signal loss , can not be recovered quickly; short service life, poor reliability

Abstract

The invention discloses a mobile satellite communication phased array antenna, which relates to a high performance satellite communication antenna device of a mobile satellite communication system in the communication field. The invention comprises a receiving array, a transmitting array, a feed network, a radio frequency receiving component, a radio frequency transmitting component, a servo tracking and beam controlling system, and an antenna seat and other components. The invention adopts a form of a one-dimensional phased array scanning antenna, a track mode of mutually combining azimuth plane mechanical tracking and pitching surface phased array electric track while scan is formed by adopting a non-planar array form structure, and the receiving and the transmitting of signals are completed. The invention also has the advantages that the tracking speed is quick, the electrical performance is good, and the outline is low, etc. The invention is in particular applied to the manufacturing of the high performance satellite communication antenna in the mobile satellite communication system.

Description

Technical field [0001] The invention relates to a mobile satellite communication phased array antenna in the communication field, and is particularly suitable for the manufacture of a high-performance satellite communication antenna in a mobile satellite communication system. Background technique [0002] The antennas currently used in mobile satellite communication systems have the following structural forms. Although they have their own characteristics in performance, they all have certain shortcomings. [0003] 1. Reflecting surface antenna is the main form of satellite communication antenna at present, but its structure is large, heavy, and not easy to install. Because the reflector antenna requires two-dimensional mechanical tracking, under the conditions of mobile satellite communication, its tracking speed is slow, and it is difficult to ensure tracking performance. [0004] 2. The low-profile multi-group array antenna adopts the multi-group array method to achieve low pro...
