便携式卫星通信地球站电磁辐射环境影响分析研究 A A b b s s t t r r a a c c t t A A b b s s t t r r a a c c t t In recent years,there are so many natural disasters in the world.Portable satellite communication earth station system, which requires a low quality working environment and performs high reliability,short response time, flexibility network, can responds rapidly and sets up a satellite link within few minutes to achieve date transmission and real-time video broadcast. so it is more and more widely used. At the same time, the possible environment problem of the electromagnetic radiation during the satellite communication earth stations working time causes more and more peoples attention. The research of our topic is based on the portable satellite communication earth station system and cooperates with Beijing AKD information telecommunication Co.,Ltd.We get the antenna gain through a beacon tower method and analyse the electromagnetic radiation problem using the RF theory, then get the safety reports compared a large number of theoretical and measured data with the national safety limits.For the first time, we have a fully test and verification about the AKD antennas electromagnetic radiation limits ,which may bring practical significance for antenna making and technology improving in the future,and which may bring reality significance for the health of the surrounding people.
