摘要
天线是发射或接收系统中经设计用于辐射或接收电磁波的部分,用于接收状态时天线接收来波,并将其引向连接着传输线的公共馈点。表面电流分布是天线的重要参数。通过以RWG(Rao-Wilton-Glisson)边元为基础的矩量法,使用Matlab软件工具,对给定结构和入射电磁信号的接收天线进行分析计算,创建RWG边元,求解阻抗矩阵和矩量方程,得到了天线的表面电流分布,并将表面电流分布可视化。
Antenna is a part which is designed to radiate or receive electromagnetic wave in transmission or receiving system, in receiving mode antenna receives wave and leads it to common feed point which connects to transmission wire. The distribution of surface currents is an important antenna parameter. To the given structure and incident electromagnetic wave receiving antenna, through RWG-based momentum method with Matlab software. This paper established RWG elements, solved impedance matrix and momentum equations, achieved the compute of the distribution of antenna surface currents, and made it visible.
