遗传算法在优化设计宽频微带天线中的应用

The Application of Genetic Algorithm for the Design of a Broadband Microstrip Antenna

将遗传算法与FDTD法结合优化设计出了一种宽频微带天线。文中简要讨论了遗传算法的操作过程,并介绍了减少遗传算法与FDTD法结合优化微带天线计算量的方法。与初始矩形微带天线相比,优化后天线的阻抗带宽增加了三倍多。

Genetic Algorithm combined with FDTD method is applied to design a broadband microstrip antenna. We discuss how to operate genetic algorithm and introduce some techniques to reduce the time of optimizing a microstrip antenna with genetic algorithm and FDTD method. Comparing with the original square microstrip antenna, the optimized patch antenna achieves more than three times improvement in impedance bandwidth.
