摘要
基于短波同相水平天线,设计出一种短波相控平面阵列天线。该天线阵为矩形栅格平面阵天线,采用4(4个半波振子作为辐射单元。通过改变天线阵馈电网络移相量,改变天线阵波束指向,构成一种方位波束可控的相控平面阵天线。对该相控平面阵天线进行了深入的数学分析,求解辐射单元最佳激励。计算仿真结果表明,该相控天线具有较好的阻抗特性及辐射特性,满足给定方向上的短波通信要求,具有较高的应用价值。
Based on the horizontal cophased shortwave antenna,a short wave phased planar array is designed.The planar array is a rectangular grid array antenna.It uses （4 （4） half-wave vibrators for radiation unit.By changing the phase shift amount of feed network of antenna array,the beam direction of antenna array is changed,so the horizontal cophased antenna is built.Thorough mathematical analysis the best excitation signal of radiation unit of the planar array has calculated.The result of calculation and simulation shows that the planar array has good impedance characteristics and radiation characteristics.It meets the requirements for short wave directional communications and has the higher application value.
