A Left-Handed Transmission Lines Based on Coaxial Waveguide

摘要

摘要: 该文提出了一种基于同轴波导的新型异向传输线，与现有基于微带电路的异向传输线相比，这种结构有更高的工作频率、损耗较低和更大的功率容量；与基于同轴波导和矩形波导的异向传输线相比，其结构更简单容易实现。等效电路与有限元仿真的结果均表明这种结构在特定的频段表现出明显的异向特性。

Abstract: A novel Left-Handed Transmission Lines (LHTLs) based on coaxial waveguide is presented, compared with the LHTLs based on microstrip, the new structure has higher operating frequency, lower loss and higher power capability; compared with the LHTLs based on coaxial waveguide and rectangular waveguide presented recently, it has a simpler structure and is more easily to realize; The results of equivalent circuit method and finite element simulation show that the structure exhibits obvious left-handed behavior in a specific frequency range.
