摘要: 应用FDTD方法分析TEM喇叭天线阵列的瞬态辐射特性，分析了阵列单元之间的互耦对天线阵列远场辐射的影响。当TEM喇叭天线阵列单元沿E-面叠状排列，阵元间互耦可以改善阵列的低频辐射；沿H-面排列的槽状线阵或平面方阵不利于阵列的低频辐射的改善。用半TEM喇叭天线组成槽状排列和叠状排列的二元线阵和四元线阵，进行了相应的原理性实验，实验结果与理论数值模拟基本一致。

Abstract: This paper analyzes transient radiation of transverse electronmagnetic(TEM) horn antenna arrays with FETD method. Influence of the mutual coupling between the elements on far-field radiation is analyzed. The radiation performance at lower frequencies can be improved using the stacked TEM-horn configuration and decreased using rain gutter and square plane TEM-horn configuration. Rain gutter and stacked two-element of half TEM-horn arrays and four-element of half TEM-horn arrays were investigated by simulation and experiments. Experiments of TEM-horn array verified the result of the FDTD simulations．
