基于多开口谐振环的双频左手材料设计

Design of dual band left-handed material based on multiple split resonator ring

基于多开口谐振环结构,提出一种双频宽带左手材料.结构由正方形谐振环与工字型负载线组合而成,具有频带宽、频率可调与易于加工的特点.通过软件仿真与样品测试提取等效介质参数,结果表明该结构左手频带分别位于7.8～8.2GHz和8.4～13.4GHz,左手带宽共计5.4GHz.相较于传统结构,该结构带宽更宽且在一定范围可对左手频带进行调节.

Based on the multi-split resonant ring structure,a dual band broadband left-handed material is proposed.The structure is composed of a rectangular resonant ring and inverted H-shaped load line,and it has a wide frequency band,adjustable frequency and is easy processed.The parameters are extracted by software simulation and physical test,and the results show that the left-handed bands of the structure are located at 7.8-8.2 GHz and 8.4-13.4 GHz respectively,and the total bandwidth is 5.4 GHz.Compared with the traditional structure,this structure has wider bandwidth and can adjust the left-hand band in a certain range.
