摘　　要：分析了常见文献中关于均匀直线式天线阵分析所存在的问题及不足.对均匀直线式天线阵空间方向图进行了详细分析,给出了数学分析计算公式.以实例介绍了如何分析均匀直线式天线阵立体空间方向图.文中的方法及结论也适用于由磁偶极子、短偶极子、半波或全波单元天线组成的均匀直线式天线阵.This paper pointes out some problems and insufficiency existing in some familiar literatures relating to the directivity pattern analysis of the uniform linear antenna array.On the other hand,it analyzes in detail the spatial direc tivity pattern of the uniform linear antenna array and gives the calculating formulas about antenna array spatial directivi ty pattern.It introduces how to analyze mathematically three-dimensional directivity pattern of the uniform linear anten na array with an example.The method and the conclusions in this paper are applicable for the uniform linear antenna ar ray constructed by magnetic dipole antenna,short dipole antenna,half-wave dipole antenna or full-wave antenna.
