提出了一种具有双面金属图案的新型平面复合左右手传输线，该传输线具有高可扩展性和低成本的优点。的不平衡和平衡的CRLH TL的基本特性的数值和理论上都证实了全波有限元法（FEM）模拟和等效电路分析的色散特性和特性阻抗的周期性结构。研究还表明，左手电路参数与单胞几何参数之间的关系简单直观，这对CRLH TL的设计很有帮助。对10单元非平衡和平衡CRLH TL进行了实验，通过散射参数和近场测量证实了左手波和右手波的传播。
A novel planar composite right/left handed (CRLH) transmission line (TL) with double-sided metal patterns, which is advantageous in high scalability and low-cost fabrication, is proposed. Fundamental characteristics of the unbalanced and balanced CRLH TLs are confirmed numerically and theoretically both by full-wave finite-element method (FEM) simulations and the equivalent circuit analysis in terms of dispersion characteristics and characteristic impedances for the periodic structure. It is also shown that the relations between the left-handed circuit parameters and the geometrical parameters of the unit cell are simple and intuitive, which is useful for designing the CRLH TL. Experiments on 10-cell unbalanced and balanced CRLH TLs are carried out and the left-handed and right-handed wave propagations are confirmed by scattering parameter and near field measurements.
