A Left-Handed Transmission Lines Based on Coaxial Waveguide
一种基于同轴波导的异向传输线

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.
