摘要
将遗传算法与矩量法相结合，对可重构线天线的开关状态进行优化设计．将可重构天线的开关作为加载来处理，并利用Sherman-Morrison-Woodbury公式加速矩量法中阻抗矩阵方程的求解．优化结果表明遗传算法与快速矩量法结合对可重构线天线的优化设计非常有效，优化设计的速度提高了3～4个数量级．
A reconfigurable wire antenna is optimized by the method of moment （MoM） combined with the genetic algorithm （GA）. The switches of the reconfigurahle antenna are regarded as loads, and the Sherman-Morrison-Woodbury equation is used to accelerate the calculation of the impedance matrix equation in MoM. The optimized results indicate that the combination of GA and the MoM is a very effective method to optimize the reconfigurable wire antennas, and the speed of optimization is improved over 3-4 orders of magnitude.
