摘　　要：采用螺旋式结构以及加载的方法可以使天线小型化和宽带化。研究遗传算法和有限元法相结合的方法来快速优化设计宽带小型化加载法向模螺旋天线。采用基于变分原理和剖分插值为基础的有限元法来快速精确分析法向模螺旋天线,然后结合遗传算法对加载法向模螺旋天线上的加载集总元件的值、加载位置以及匹配网络参数进行一体化优化设计,并采用Sherman-Morrisorr Woodbury公式来快速求解加载元件值和加载位置改变后的阻抗矩阵方程,提高优化设计的效率。Spiral-type structure and the loading method can make the antenna smaller and broadband. Study of genetic algorithms and finite element method with the method to quickly optimize the design of broadband loaded small normal mode helical antenna. Based on variational principle and split-based interpolation finite element method for fast and accurate analysis of normal mode helical antenna, Combination of genetic algorithm and then load the normal mode helical antenna loaded on the value of lumped elements, Load location, and matching network integrated optimal design parameters. And Sherman-morrisorr Woodbury formula is used to quickly solce the load component values and load the changed position of the impedance matrix equation to improve the efficiency of optimized design.
