摘　　要：设计了一种采用五级缝隙耦合结构的超宽带定向耦合器,工作频段为3～18GHz,整个频段范围内,输入端口驻波小于1.5,隔离度小于15dB,幅度不平衡度小于1dB,相位不平衡度小于5°,且具有结构简单、工艺上易实现等优点。In this paper,a five-section slot-coupled UWB directional coupler is presented.The coupler oper- ates over a band width from 3GHz to 18GHz.A model has been simulated which exhibits a VSWR less than 1.5 at input,isolation less than 15dB,amplitude imbalance between outpu：s less than 1.5dB and phase imbalance less than 5° across the 3GHz-18GHz band.And also,this design has a relatively simple structure which is easy to implement in technology.
