将时域有限差分法(FDTD)应用于宽带微带天线的分析设计,模拟微带天线的电磁辐射过程,从而得到天线的输入阻抗、带宽和方向图等特性.借助于EMPIRE软件,设计了一个宽带微带天线,其中心工作频率为 10. 37GHz,相对带宽达到了 21. 7%.
Abstract：Finite-Difference Time-Domain (FDTD) is applied in analyzing and designing of a broadband microstrip antenna,the microstrip antenna radiation process is simulated,and the input impedance,bandwidth and radiation pattern of the antenna are obtained.By using EMPIRE software,a broadband microstrip antenna is designed with central frequency of 10.37GHz and relative bandwidth of 21.7%.
