PSO算法在天线宽带匹配中的应用

Application of PSO Algorithm in Antenna Broadband Matching

将粒子群优化算法（Particle Swarm Optimization,PSO）用于天线宽带匹配网络的优化设计,通过选用合适的拓扑结构和目标函数,对网络中的各个参数进行优化,取得了满意的匹配效果。最后,通过两个实例验证了PSO算法设计的宽带匹配网络具有更优的匹配性能,说明该方法是一种设计宽带匹配网络的有效方法。

In this paper, the PSO （Particle Swarm Optimization） algorithm is employed to design the broadband antenna matching networks. By choosing the appropriate topology and the objective function, opti- mizing the element of the networks, a satisfying effect can be achieved. Finally, two designed examples are sup- plied, and the results show that the performance of the matching networks is much better than that obtained from other methods. Thus, PSO Algorithm is an effective method for designing matching networks.
