摘　　要：研究并设计了一种工作在Ku波段的溅散板型抛物面天线.利用电磁仿真软件CST进行仿真设计,完成了天线结构参数的提取和电气性能的分析.并对样件进行实际测试与调试,测试和仿真计算结果基本一致,远场方向图完全满足ETSI Standard Range1 Class2包络电气要求.与现有的溅散板馈源相比,具有开口辐射波导终端匹配性好、天线电压驻波比小(小于1.3∶1)、低风载负荷、低制造成本等优点;天线效率在60%以上,介质赋形简单,易于批量生产.A splash plate antenna which works in the Ku-band was researched and realized Extraction of antenna structure parameters and analysis of electrical performance were accomplished by using simulation software CST. The designed antenna was fabricated and tested and the tests were in consistent with simulation results. Far field pattern fully met the requirements of ETSI Standard Range 1 Class2 envelope. Compared with existing antennas, the antenna has better matching performance in the open radiating guided end, lower VSWR （VSWR〈1.3：1）, lower wind load and lower manufacturing cost. Antenna efficiency is more than 60%, and the shape of dielectric is simple, convenient for production on a large scale.
