摘　　要：星载宽波束天线是星载天线领域的重要组成部分,宽波束天线安装在卫星平台上的整星性能分析是工程上一项难题,常规的电磁计算方法在计算速度与精度上均不能满足工程要求。文章给出了一个星载天线整星性能分析的实际案例,通过两种不同的电磁计算软件,采用不同电磁计算算法进行相互验证,提高了天线电性能分析的准确性,并通过了实际工程应用的考核。The wide-beam antenna,as an important category of space-borne antennas,presents a challenge for antenna engineers when the performance mounted on the satellite platform is expected. The conventional electromagnetic computational methods could not satisfy the engineering requirements considering the calculation speed and accuracy. In this paper,a case study for analyzing the antenna performance on the spacecraft is given by utilizing two kinds of simulation software for mutual verification. The accuracy of this method has been proven in engineering applications.
