matlab编写的FDTD（时域有限差分法）程序，可以实现完整天线方向图和反射系数的计算，以贴片天线为例，对比了编写程序的反射系数与方向图和HFSS计算的反射系数与方向图，具有一致性。
English Description：
FDTD (finite difference time domain method) program written by Matlab can realize the calculation of complete antenna pattern and reflection coefficient. Taking patch antenna as an example, the reflection coefficient and pattern of the program and the reflection coefficient and pattern calculated by HFSS are compared, which are consistent.
