摘　　要：基于矩量法推导了天线的等效电路模型,将可重构天线看作多载天线系统,提出一种基于全波/网络混合法的可重构天线仿真方法,该方法采用全波仿真软件计算无加载的天线阵列,结合遗传算法,采用网络分析法分析任意加载天线阵列性能。采用该方法对一种寄生偶极阵列天线的波束形成性能进行了仿真分析,并与商业电磁仿真软件的仿真结果进行了比较。结果表明,该方法计算结果正确,大大降低了可重构天线仿真分析的计算量,提高了仿真分析效率。The equivalent circuit model of an antenna array is derived based on the method of mo- ments （MoM）. The reconfigurable antenna will simulation method of the reconfigurable antennas be seen as a multi-loaded antenna system, and a is presented, in which the full-wave simulation is adopted for the unloaded array, while network analysis is used along with genetic algorithm to search for network characteristics and radiation patterns of the arbitrary loaded arrays. Using this method, a dipole array antenna is simulated to find the beamforming performance of the array, and with the commercial electromagnetic simulation software, simulation results are compared to verify the cor- rectness of the method. The results show that this method greatly reduces the computation in recon- figurable antenna simulation analysis, and improves the simulation efficiency.
