摘要
本文运用时域有限差分（FD-TD）法，对微带天线的电磁特性进行时域仿真。首先是对算法的原理介绍及其在仿真软件中具体实现方法作概要说明；然后分别阐述仿真解在时域和频域中的各项应用；最后，采用该仿真技术，实例分析若干天线性能，使之成为微带天线工程设计中一种方便经济的辅助手段。
The electromagnetic behaviors of microstrip antenna are simulated in time domain by using Finite-Difference Time-Domain (FD-TD) method. In this paper, the principle of the numerical algorithm along with its implementation is briefly, introduced at first. Then the applications of the simulation solution in both time domain and frequency domain are presented respectively. Finally, serving as a convenient and economical auxiliary means of antenna design,the simulation technique is used to analyze the properties of several antennas.
