摘要
采用矩量法计算了2元和6元鞭天线线性相控阵的方向图,分析了天线单元之间的耦合对方向图的影响,计算结果表明,鞭天线单元间的耦合对相控阵方向图的主瓣影响不大,对旁瓣产生一定影响,且对偏离主瓣越远的旁瓣影响越严重;方向图中增益低的方向受耦合的影响较严重。
The radiation patterns of a collinear phased array consisting of 2 or 6 whip elements are studied by MOM. The influence of element coupling to array radiation pattern is analyzed. Results indicate that element coupling influences little to the main lobe, but much more serious to the side lobe, so do those offset directions from the main lobe.
