共形安装于特定平台、具有初步构型方案的复杂结构特型天线,其辐射全向性、定向增益、雷达波散射截面积等特性均需要满足特定的设计指标。同时,复杂天线的外形结构具有多个尺寸参数,均为详细设计的量化对象。为得到相对最优的天线详细设计方案,可针对天线的多个结构参数,将全波精确电磁计算方法和优化算法相结合,进行迭代。论文针对典型案例,通过粒子群(PSO)优化算法驱动矩量法(MoM ),对特型天线的概念结构方案进行迭代优化,形成综合性能指标相对最优的设计方案。

For the antennas which conformal to the specific platform for specific use ,the design starting from an initial configuration scheme should focus on different kinds of antenna performances ,including ideal omni‐directional pattern ,high directive gain ,and its RCS .In order to achieve the relative optimal design scheme ,simulation with full‐wave algorithm should be combined with numerical optimization for variable structure dimensions of the antenna .In this paper ,with MoM diven by PSO ,the conceptual design of an antenna with special form is optimized .After thousands of iterations ,the design with an optimum overall performance is obtained .
