| 摘 要： | 用时域有限差分法（Ｆｉｎｉｔｅ Ｄｉｆｆｅｒｅｎｃｅ Ｔｉｍｅ Ｄｏｍａｉｎ Ｍｅｔｈｏｄ）计算天线阻抗特性，可以使用不同的激励方式，文章比较了采用不同激励方式时，天线的输入阻抗。文中的主要内容是将表面阻抗法用于ＦＤＴＤ中，计算架设在介质平面上单极天线的辐射特性，并用ＦＤＴＤ法计算了介质平面上铺设不同尺寸的导体平面时，单极天线的输入阻抗随导体平面尺寸变化的特性。

| Abstract: | Differential feed models can be used to calculate radiation characteristics of antenna. The input impedance calculated with differential feed models had been compared. The importation point was to calculate radiation characteristics of monopole antennas on dielectric plane, and analyze input impedance change with the size change conduction ground system on the dielectric plane. |
