基于HFSS-MATLB-API的天线布局优化仿真
|
摘要
随着用于车载平台的天线数量日益增多,汽车的电磁兼容问题日益严重.针对天线布局缺少统一合理模型和理论方法指导的现状,利用HFSS-Matlab-Api脚本库在Matlab中调用HFSS建模进行天线布局的电磁兼容性仿真,采用遗传算法对布局进行优化.此方法省去人为数学模型推导过程,减少用户反复绘制模型、修改参数的重复工作.不仅充分利用HFSS仿真的高精度、可靠性和便捷性,而且采用遗传算法减少盲目的试探带来的时间和成本的浪费.最后,得到与理论相符合的实验结果,从而验证了布局与优化方法的可行性.
With the increase of the number of antennas applied in the mobile platform, the electromagnetic compatibility problems of cars are becoming more and more serious. According to current situation of antenna layout lacking reasonable model and theoretical method, Matlab is used to control HFSS to generate different models for simulating and optimizing electromagnetic compatibility of the antenna layout by HFSS-Matlab-Api Script library. Using genetic algorithm to optimize layout. This approach can save mathematical model derivation process and reduce the work users repeatedly draw model and modify parameters of duplication. This approach can make full use of the simulation precision, reliability and convenience of HFSS, and using genetic algorithm to reduce the time and cost of blind test. In the end, the experimental results are consistent with the theory, thus verifying the feasibility of layout and optimization method.
