摘　　要：该文应用时域有限差分法(FDTD)分析了同轴馈电E形宽带微带天线的阻抗特性,此天线的阻抗带宽可大于30%.计算中采用了一种简单的同轴馈电模型,数值结果与已有文献结果比较一致,说明了此模型的有效性.同时,也研究了输入电阻随馈源位置变化的特性.The impedance characteristics of the wideband Eshaped microstrip antenna is analyzed by using the FDTD method. The antenna bandwidth of impedance can exceed 30%. A simple model of coaxial feed is presented. Its calculated results are compared with the reference, and a good agreement is obtained, showing the validity of this model of coaxial feed. In addition, the input resistance variation with the feed position is investigated.
