| 摘 要： | 文章提出了一种新颖的一维左右手复合传输线结构，该结构更加紧凑，尺寸小。基于此结构所设计的3dB平行线耦合器可在宽频带内实现所要求的耦合度。通过实验仿真还可证明，通过改变单元结构级联的个数或调整耦合平行线的间距，在较宽频带内可以得到任意分贝的耦合度。

| Abstract: | A new one dimension composite right/left-handed transmission line metamaterials is designed.The size is small and compact.The Coupled-Line Directional Coupler of 3 dB based it can be achieved at wide bandwidth.The simulation indicates that it can get any coupling by changing the numbers of metamaterials or interval of the coupled-line. |
