摘　　要：设计了一种S波段圆波导缝隙全向天线,该天线是在圆波导柱面上开凿一定数量的纵列缝,组成缝隙阵列。经过仿真优化设计和测试,天线在360°方位面范围内幅度起伏小,具有很好的全向特性,目前天线已成功地应用到了雷达产品中。An S-band omnidirectional circular waveguide-slotted antenna is designed; a slotted array is formed by some amount of vertical slots made on cylindrical of circular waveguide. Through simulation optimum design and test, the designed antenna features low amplitude fluctuation in azimuth （360~） and good omnidirectional perform- ance. It has been applied to radar successfully.
