摘要 首先基于复合左右手传输线和微带缺陷结构提出了一种新型双螺旋微带缺陷谐振单元,并研究了其幅度特性和相位特性。然后,研究了其结构参数对传输特性的影响。最后,运用该新型双螺旋微带缺陷结构设计了一个小型化分支线耦合器,仿真及实测结果表明:该分支线耦合器不仅实现了62.8%的小型化,而且避免了后向辐射的问题。 In this paper,on the basis of composite right/left handed transmission line and microstrip defected structure a novel double-spiral-defected microstrip resonator cell（DMRC） is proposed firstly,with its characteristics studied.Then the reflection of structure parameter to transmission characteristics is analyzed.At last, a miniaturized branch-line coupler is designed uti- lizing the new structure.Consistent simulated and experiment results have confirmed the design concept and indicated that the proposed coupler has a 62.8% of size reducing and no backward radiation.
