本文使用三维FDTD算法实现文献《Application of the three_Dimensional Method to the analysis if Planar Microtrip Circuits》IEEE trans. On MTT 1990 38(7)的一个矩形微带贴片天线的S11参数的计算。采用MATLAB编程完成数值计算，并与文中的结果进行了比较。(This three-dimensional FDTD algorithm using the document " Application of the three_Dimensional Method to the analysis if Planar Microtrip Circuits" IEEE trans. On MTT 1990 38 (7) of a rectangular microstrip patch antenna of the S11 parameter of the calculation. Complete the numerical calculation using MATLAB programming, and with the text of the results were compared.)
