中文摘要：

本文提出了基于正六边形多开口的新型双频带磁谐振体.在微波衬底材料的一面放置交错多开口的两个正六边形金属环,多开口结构破坏了环间耦合电容,从而使两环形成相对独立的两个谐振网络实现双频带效应.最后将该谐振结构的另一面放置金属导线形成一个双频带的新型左手材料.文中利用HFSS软件仿真和等效参数提取的方法,分析和验证该结构的正确性.

英文摘要：

This paper presents a novel dual-band magnetic resonance with multi-defect hexagonal structure.Staggered defects double hexagonal metal rings was put on a microwave substrate.So the coupling capacity of the two rings was damaged.Then the dual-band magnetic resonance has been obtained.The traditional structure of dual-band is very complicated.But the new structure is simple and the size is also very easy to control.Finally,we combined the novel structure with metal wires to make dual-band left-handed metamaterials.From the result of the HFSS simulation,this left-handed metamaterials has obtained dual-band at 6.5—7.0 GHz and 8.8—9.3 GHz.The dual-band left-handed structure has a great infuence on the microwave flter,antenna,and other microwave devices.
