摘　　要：采用近邻粒子群算法设计了一个安装于非规则曲面上的微带共形阵。通过测量安装于非规则曲面上的天线单元的方法,将载体对共形阵的影响计入天线设计中。采用近邻粒子群算法对单元进行了优化,根据优化结果制作了微带共形阵,给出了非规则微带共形阵的驻波曲线和远场方向图。实验结果表明,近邻粒子群算法能够有效地对复杂曲面上安装的共形阵进行设计。A conformal microstrip antenna array mounted on an irregular dielectric surface is developed using Fitness Distance Ratio （FDR） based Particle Swarm Optimization （PSO） in this paper, Patches mounted on the irregular surface are measured in order to take into account the effect of the irregular dielectric platform on the conformal array during the pattern synthesis procedure. The phases of the elements are optimized using FDR-PSO. The conformal array is fabricated and experimental results including VSWR and radiation patterns are given. The experimental results show that FDR - PSO is an effective method for conformal array antenna design.
