| 摘 要： | 单平面双螺旋谐振单元是一种左手单元,具有不需缺陷地结构和小型化的特点.该文主要对由单平面双螺旋单元组成的对称和非对称两种传输线形式进行了仿真研究.利用电磁仿真工具,仿真分析了两种形式传输线的回波损耗和插入损耗特性.由仿真结果可知,非对称形式传输线的电磁性能较好.该文设计了两组对比仿真实验,即对称和非对称形式传输线结构相位特性对比,一、四单元非对称传输线相位特性对比,对传输线结构的相位特性进行了分析.结果表明,基于单平面双螺旋结构的非对称形式传输线具有左手效应.

| Abstract: | The uniplanar double spiral resonator is a kind of left-handed unit which does not require the defected ground and can be miniaturization.Through simulation method,we mainly investigated two kinds of transmission lines:symmetrical shape and unsymmetrical shape,composed of uniplanar double spiral resonators.Using HFSS,the return loss and inserted loss characteristic was simulated and analyzed.It was found that the unsymmetrical shape transmission line had better electromagnetic characteristic than the symmet... |
