摘要
对基于单平面双螺旋谐振单元的左手传输线进行了研究。对设计的单平面双螺旋单元结构的电磁特性进行仿真并与实际测量结果比较。用散射参数提取算法提取了该结构的折射率和相位常数,提取结果表明上述参数在特定频段同时为负,证明该结构具有左手特性。提出调整螺旋圈数控制传输线电磁特性的方法。通过仿真总结和检验了该参数的调整规律。
The electromagnetic characteristic of left-handed transmission line based on uniplanar double spiral resonators were studied in this paper. The electromagnetic characteristics of uniplanar double spiral resonator structure designed were simulated, which were compared with the measure results. The refractive index and phase constant using the extraction algorithm were extracted. The results showed that the mentioned parameters were negative within special frequency band, which proved that the structure was left-handed. The method to adjust the number of rings for controlling the electromagnetic characteristic was put {orward. The controlling law was summarized and approved by the simulation.
