摘　　要：从对数周期偶极子天线(LPDA)特性和结构出发,通过数学建模,定量计算出对数周期偶极子天线的空间场型分布。针对不同天线阵子数下的水平和垂直剖面的方向图,根据辐射分布特征,给出优化结构。结合浦东机场使用的NORMARC航向天线进行建模仿真,对天线的特性研究、测试和维护有指导意义。According to the characteristic and structure of LPDA, a 3D model is established, and the space performance of LPDA is also presented quantitatively. The horizontal and vertical patterns of various dipoles are also designed. An optimized structure is supported. Simulation is integrated to the LPDA used in Pudong International Airport by NORMARC Company. It had great significance for the feature study, testing and maintenance of LPDA.
