摘　　要：讨论了圆极化径向线缝隙天线的几何结构、口径场分布、缝隙对设计。在此基础上 ,讨论了慢波结构和波导结构关系 ,分析了慢波结构对天线的影响 ,完成了该天线的计算机辅助设计和绘图 ,使用该方法给天线设计带来了方便 ,能灵活地调整缝隙排列、优化排列结构 ,具有直观和精度高的优点。The design of CP RLSA is provided in this paper. The antenna is of high efficiency and high gain, used in the broadcasting, television and communication of DBS, VSAT as well as various kinds of land mobiles (vehicle and ship) receiving the signals from the satellites. The paper achieves the purpose of CAD and drawing on the principles of CP RLSA. This method can flexibly adapt and improve the slot arrays, which brings convenience directness and accuracy to the design of antennas. This paper also discusses the influence of slow wave structure to antenna efficiency.
