适用于可重构微带天线仿真设计的免疫算法

摘要

By combining the commonly used MOM in antenna design with immune algorithm, the paper optimizes the design for reconfigurable antenna and analyzes the advantages of immune algorithm in reconfigurable antenna design. By absorbing research fruits on GA- based antenna, the paper applies immune algorithm to add MEMS switch to antenna structure for simulation, hence designs two microstrip dual-reconfigurable antennas that can not only carry out pattern scanning changes on a fixed frequency, but also realize frequency flexible changes on a fixed pattern.%将天线设计中常用的矩量法(MOM)与免疫算法相结合对可重构天线进行优化设计,分析免疫算法在可重构天线设计的优势.在归纳总结近几年基于遗传算法的天线的研究成果的基础上,通过免疫算法在天线结构中加入MEMS开关进行仿真计出两种既可以在固定频率点上进行方向图的扫描变化,又可以在特定的方向上实现频率灵活变化的微带双重可重构天线.
