摘　　要：论文设计了一种能够实现脉间变极化的X波段正交极化电偶极子天线阵的阵元。该阵元由一组水平交叉放置的铜质电偶极子组成,下方加装反射板以优化阵元的方向图。通过仿真软件建立阵元模型后,对电偶极子的尺寸进行更改,不断优化其主要参数;对最优方案进行仿真验证,结果表明该设计方案具有较小驻波比、较高隔离度,满足实际工程中的使用要求。An X-band orthogonal polarization electric dipole antenna array element is designed in this paper.The array ele⁃ment is composed of a group of copper electric dipoles placed horizontally and a reflection plate is installed below to optimize the ar⁃ray element direction diagram.After the matrix element model is established by simulation software,the size of the electric dipole is changed and its main parameters are optimized constantly.The simulation results show that the design scheme has a small standing wave ratio and a high isolation degree,which can meet the requirements of practical engineering.
