| 摘 要： | 为提高旋转对称天线的计算精度,在等效矩量法(MOM)的基础上,对旋转对称天线表面电流作离散处理,根据伽列金法给出了天线表面的电场积分方程(EFIE),用朱兰成公式求得天线远场。对某旋转对称天线不同频率处的方向图计算结果表明,与等效MOM相比,该法的精度更高。

| Abstract: | To improve computation accuracy of rotationally symmetric antenna,an extended moment of method(MOM) was put forward based on equivalent MOM in this paper,in which surface electricity of the antenna was scattered,electric field integral equation on the surface of the antenna was given according to Galerkin method,and far-field of the antenna was calculated by the Stratton-Chu equation.The computation result for some rotationally symmetric antenna under various frequencies showed that the accuracy of the method in this paper was higher than the one of equivalent MOM. |
