传输线矩阵(TLM)方法在分析天线阵辐射特性中的应用

The Application of TLM Method for Analysis of the Radiation Characteristics of Antenna Arrays

本文运用传输线矩阵(Transmission-line Matrix.TLM)方法分析由理想点源构成的直线天线阵的中间区和远区的场特性,并对天线阵的辐射方向图进行了数值计算:本文计算结果与解析分析结果吻合得很好,表明TLM方法是分析天线阵的近区、中间区和远区场的分布特性以及辐射特性的一种较好的方法.

In this paper, the application of TLM method to analyze the characteristics of middle and far field distribution of line antenna arrays is verified. The simulation results of radiation pattern are presented and agreed well with the analytical results. It is shown that TLM method is a good numerical method for analyzing the field characteristics of near, middle and far zoon of line antenna arrays.
