| 摘 要： | 将一种新的混合方法-FEM/PO-PTD方法，应用于分析计算背腔式微带天线的电磁散射特性。通过无穷大接地导体平面上矩形背腔式微带天线的RCS计算，验证了该方法的正确性。在此基础上，计算了两组有限尺寸金属载体上背腔式微带天线的RCS曲线，理论分析与计算结果表明，该混合方法具有计算机内存需求少、计算时间短等优点。

| Abstract: | In this paper, a hybrid technique FEM/PO PTD method is applied in solving electromagnetic scattering by microstrip patch antennas residing in a cavity. The RCS's of a rectangular cavity backed aperture in an infinite ground plane and two cavity backed microstrip antennas mounted respectively on a finite metal object are calculated and analyzed. The numerical results show the efficiency of the technique with some advantages in saving computer memory and CPU time. |
