摘　　要：设计1种用于平板阵列“动中通”天线的双极化方形角锥喇叭天线单元,将交叉极化耦合孔设置在喇叭波导的同1侧,并都采用竖缝形式进行耦合,实现了天馈系统的一体化结构设计,降低了天馈系统高度和复杂度。优化设计了切比雪夫阻抗变换段和极化旋转阶梯,实现了双极化交叉辐射和宽频带匹配。仿真结果表明双极化辐射明显,远场方向图一致性较好,端口隔离度高,满足工程设计要求,为“动中通”平板阵列提供了1种较好的辐射单元天线。A Dual-polarized Horn Antenna unit of planet array for Mobile Satcom is proposed in this paper.By Slotting two same coupling hole on the one side of the horn wave guide,the antenna system realized Integrated Structure Design,reduced the height and the complicacy.The Chebyshev transformer and polarization rotation steps are optimization designed for realizing the dual polarized radiation and Broadband Matching.The simulation results show that this horn antenna realized the dual polarized radiarion and High Isolation of the ports.The good performance makes the Eleven antenna as good candidate for planet array antenna for mobile sitcom.
