摘　　要：采用时域有限差分法(FDTD)对微带天线与微带线之间的互耦系数进行计算.激励源采用在激励空间提取入射波,再加入到计算空间中的方法引入.提取出入射波和反射波之后进行快速傅里叶变换,再利用N端口网络的知识计算出S参数,计算结果表明使用时域有限差分法的结果和基于有限元(FEM)方法的商业软件HFSS的计算结果基本一致.With the increasing of frequency from the signals on the RF PCB,it being widespread that patch antenna and microstrip exist on a block of RF PCB,crosstalk of signal on the RF PCB is serious.It can reduce the interference on the RF PCB if the crosstalk is exactly evaluated and calculated.And the stability of the system would be improved.This paper used the finite-difference time-domain method to calculate the crosstalk between patch antenna and microstrip.The source was set by trained in incentive space and set in space of calculation.The incident wave and reflection are stored,and transformed by FFT.The S parameter was calculated.The results of simulation were in accordance with the results of HFSS.
