| 摘 要： | 设计了一种微带馈电双极化喇叭天线。该喇叭天线的辐射层中心为一圆锥喇叭孔的金属波导材料,通过双层正交的三角形带状线馈电结构来实现双极化,最下层加入金属反射腔来抑制背向辐射,提高天线增益。利用HFSS电磁仿真软件对天线进行优化仿真,仿真结果表明,该喇叭天线在Ku波段上行(14.0～14.5 GHz)和下行(12.25～12.75 GHz)的反射系数VSWR均＜2,两个端口的增益均＞8 dB。该喇叭天线体积小,增益高,采用微带馈电的形式,适合作为Ku波段卫星地面通信系统的天线单元。

| Abstract: | A novel dual-polarized microstrip-feed horn antenna is designed in the paper.The radiation element is metal material with a conical horn hole at the center.The feeding layer adopts double orthogonal microstrip-feed planes to achieve dual-polarization.A metal reflector cavity is used to suppress backward radiation and improve antenna gain.HFSS simulation results show that the VSWR of the novel horn antenna is less than 2 in the Ku-band uplink (14.0～14.5 GHz) and downlink (12.25～12.75 GHz) and the gains of the two ports are more than 8 dB.The antenna is small in size and high in gain with microstrip-feed features,which can be used as the antenna unit of the Ku-band satellite ground communication system. |
