基于 Matlab 的平面天线阵仿真研究

内容简介：针对平面天线阵的辐射能力问题，使用鞭天线作为天线阵阵元构建了一种2行4列的平面天线阵，以通信频率为12.4M Hz为例，通过Matlab分别对天线间距为10m和20m进行了仿真，得到了归一化三维辐射方向图辐射方向图，分析了天线间距与最大方向性系数的关系，同时分析了通信频率与最大方向性系数的关系，得到了设定天线阵间距可以使得定频通信的最佳的通信效果和平面矩形阵对垂直方向的调向并不敏感的结论。

Abstract：Given the radiating capacity of planar array antenna ,this paper structures a planar array antenna of two lines and four columns by employing whip antenna as array element .Meanwhile ,with the communication frequency of 12 .4MHz , it carries out simulations respectively when the antenna spacing is 10 meters and 20 meters ,and obtains a normalized 3 d ra-diation pattern .Moreover ,by analyzing the relationship between antenna spacing and the maximum directivity factor ,and the relationship between communication frequency and the maximum directivity factor ,it comes to the conclusion that by set-ting the antenna spacing the best communication effect of the fixed frequency communication is insensitive to planar rectangu-lar-array's shifting to vertical direction .
