Problems solved by technology

This method can switch between different antennas according to the different signal forms on the satellite, that is, different antennas correspond to different resources on the satellite, which can ensure that the antennas work at the same time, but when the number of antennas is large, it is inevitable that the antennas will be bulky and There are big disadvantages in terms of large amount of back-end equipment and slow tracking speed, and cannot well adapt to the needs of high-mobility platforms

[0004] 2. A mechanical mode switching device is installed in a pair of antennas. This type of mode switching device is mostly used in the feed source design of reflector antennas. Although the mode switching method of this type of system has the advantage of relatively low cost, it is in the field of satellite communications. , its size is still large, the mode switching response time is slow and other shortcomings

[0005] 3. The traditional single-mode active phased array antenna has the advantages of fast beam tracking and advanced system, but it does not have the ability to switch, and users cannot switch between inter-satellite links as needed, which makes them lose Ability to reuse functions
