摘要: 设计了一种宽波束、宽带宽的右旋圆极化卫星天线。首先使用动态多目标演化算法(DDEA)在并行计算平台上进行了全局范围内的搜索,然后使用正交试验设计和基于有限元法的HFSS软件,进行了局部范围内的均匀细化搜索,进一步改善天线增益。改进的天线,波束符合要求,可节省卫星馈电功率。

Abstract: A satellite antenna characterized by wide-beam, wide-bandwidth and microwave right-hand-circular polarization was designed. First, the Dynamic Dominant Evolution Algorithm (DDEA) was used to search globally on a parallel computing platform. Then orthogonal design and HFSS software based on finite element method were used to search within local scope evenly and elaborately, so that the antenna gain was further improved. The improved antenna meets the requirements on beam and saves the feeding power of satellite.

Key words: satellite antenna, multi-objective optimization, Evolutionary Algorithm (EA), orthogonal test
