| 摘 要： | 针对不规则贴片微带天线的准确建模与快速分析,将多区域时域伪谱(MPSTD)与时域有限差分(FDTD)两种时域算法相结合,提出了MPSTD-FDTD混合算法,以此来充分发挥两种时域算法的优越性.文中首先给出了混合算法的具体实现方法,并简要推导了混合算法中子域分界面上的匹配条件.其次,分析了算法的计算精度和影响计算精度的主要因素.最后,利用该混合算法对一种倾斜矩形贴片微带天线进行了分析,数值仿真验证了算法的有效性和准确性.

| Abstract: | In order to accurately model and quickly analyze the irregular microstrip patch antenna,the hybrid MPSTD-FDTD method is proposed based on the combination of multidomain pseudospectral time-domain(MPSTD) and finite difference time domain (FDTD),as thus,the hybrid method possesses the advantages of two time domain methods of MPSTD and FDTD.Firstly,detailed process of the hybrid method is presented,and matching condition for the subdomains interfaces corresponding with the hybrid method is derived.Secondly,the... |
