| 摘 要： | 文章用等效偶极矩方法分析金属天线的电磁辐射特性。以矩量法和RWG基函数为基础,金属天线被剖分成一定数量的三角形网格。把三角形面元对等效成电偶极子模型,当2个电偶极子模型之间的距离大于某一临界距离时,两三角形面元对之间的作用(采用一点数值积分时需4次计算)等效为两电偶极子之间的作用(仅需1次计算)。等效偶极矩法简单、易操作,数值结果表明了该方法与原方法几乎相同的计算精度。 |

| Abstract: | Electromagnetic radiation characteristics of metal antenna are analyzed using the equivalent dipole-moment method.The proposed method is based on the conventional method of moments(MoM) and the Rao-Wilton-Glisson(RWG) basis function,in which each RWG common face element is viewed as a dipole model.The action between two triangular face elements is calculated by the action between two dipoles when the distance between the equivalent dipole element and the observation point is beyond a critical distance(only calculated for once instead of four times by using numerical integration).The dipole model method is easy to operate,and the numerical results show the nearly same computational accuracy compared with conventional MoM. |
| Keywords: | method of moments(MoM) electromagnetic radiation metal antenna equivalent dipole-moment method |
