摘　　要：研究了基于矩量法和RWG三角基函数的隐式电场积分方程的时域算法,引入了一种激励源的时域设置方法。利用直接在时域加激励源的方法来分析天线辐射问题,所得时域数据经傅立叶变换可得到很宽频带的频域数据,与在频域逐个频点求解相比大大节省了计算时间。通过对几种典型天线的分析计算,验证了方法的正确性和算法的稳定性。The transient arithmetic of the implicit electric field integral equation was studied on the basis of the method of moment and RWG basis function. By adding the driving source directly in time domain, the radiation problems of antennas was analyzed, and through FFT for the data of time domain, the ultra wide band frequency data can be obtained and the calculation time was greatly saved compared with the method of frequency domain. Considering three type of typical antennas, the validity and stability of the method was proved.
