摘　　要：该文介绍了一种新型的L波段波导缝隙阵列天线设计,该天线采用金属同轴结构对辐射缝隙进行耦合馈电。馈电的同轴连接器与同轴馈电结构构成一个3 dB功分器对多个辐射缝隙进行馈电。辐射缝隙位于矩形金属腔体的上表面,辐射缝隙在矩形金属腔体的一侧且在一条线上。基于项目需求设计、加工了一套1×4单元天线线阵,测试结果表明,该天线在8%的频段内驻波比优于1.5、天线辐射效率大于80%,满足了项目的指标要求。In this paper,a novel L-band waveguide slot array antenna(WSAA)is introduced.The antenna adopts metal coaxial structure to feed the slot coupling.The feed connector and metal conductor constitute 3 dB power divider.The radiation slot is located on the surface of the metal cavity.Based on the project requirements,a demo array of 1×4 elements is designed,manufactured and tested.The experimental results show that the bandwidth of VSWR<1.5 is 8%,and the antenna radiation efficiency is greater than 80%.
