摘要
提出了基于粒子群优化算法（Particle Swarm Optimization，PSO）设计天线宽带匹配网络的方法；采用了等效阻抗方法解决了UHF频段天线宽带匹配网络实际制作中元件值随频率畸变较大的困难；最后利用上述方法设计了一付30～512MHz全向超宽频带小型化天线的匹配网络，设计结果使得带内VSWR〈3．0，并与实验结果吻合良好。
A novel global optimal designing approach called particle swarm optimization （PSO） is proposed for designing the broadband matching network of a antenna. The problem due to the aberration of value of a lumped component in UHF frequency band is solved by using equivalent impedance. Finally, based on the method above, a broadband matching network for an omnidirectional ultra-wide band miniature antenna, with VSWR 〈 3.0 in 30 - 512MHz, is designed and manufactured, and the calculated results are in good agreement with the experimental results.
