| 摘 要： | 设计一种微带天线,以该天线为基础进行飞行器天线布局设计,并考虑遮挡的判断问题。模型仿真采用多层快速多极子和有限元的方法混合求解,设置混合场积分方法提高收敛性,解决了电大尺寸模型复杂电磁场的计算问题,兼顾运算速度和精度,得出并分析飞行器上3天线、4天线、5天线以不同方式布局的远场方向图仿真结果,并提出一种方向图评估法则,对飞行器天线布局有一定参考意义。

| Abstract: | Aircraft antenna layout design is on the basis of the microstrip antenna designed, the judgment of antenna shelter also considered. multilevel fast multiple method and finite element method hybrid method are used in model simulation, CFIE method is set up to improve convergence, the electrically large complex electromagnetic field calculation problem is solved, both speed and intensive balanced. Draw and analyze far-field pattern of the different way in aircraft antenna layout, and put forward a kind of pattern evaluation rule. This paper has certain guiding significance to aircraft antenna layout design. |
