Research On Satellite Earth Station Antenna System

Satellite ground receiving station daily work and all kinds of waves are closely related, it from the ground station sent to the satellite transponder waves can be called microwave. Here, we can put the launch of the same time to receive the microwave device is called satellite launch antenna". The quality, performance and working environment of the satellite launch antenna directly affect the output of the signal, which influence the transmission power and working efficiency. Thus, the proportion of the satellite antenna in the antenna system is very large, for the entire system of the work of the antenna, it is of great significance. It can be seen from the information transmission of communication system that the main task of this antenna is the change of the uplink power carrier or the high frequency band current and the energy of the atmosphere wave. In order to accomplish this kind of complicated work effectively, it is required that the satellite transmit antenna is an excellent "electromagnetic receiving and transmitting unit". Secondly, the operating efficiency of the satellite launching antenna system is limited. There will be various reasons for the daily work, and this will lead to a general decrease in its efficiency. The amplitude frequency characteristics of the system equipment, weather conditions, operation of the equipment and so on, are the main reasons for the normal operation of the system. In order to make the antenna system work better, we need to solve these problems one by one. And in the actual test, we must ensure the normal operation of the antenna system. In addition, the application of the test equipment is also very important, the instrument used is not good or wiring loose when the test results are not accurate. So, in the latter part of the test should be more careful. The real on the satellite earth station antenna design, system test experience as the foundation, and the specific work in the test work, this antenna system from equipment, testing equipment, computer control and concrete operation and other aspects are discussed in detail. Through several aspects of this research and testing and practical application, finally let the satellite earth station antenna system can play its own more efficiency in practical work, so that the entire satellite launch system produced important reactions.
