Abstract

In order to enhance information capacity and accommodate the rapid development of modern science and technology, design of left hand materials with the broadband and multiple frequency resonant characteristics has gained great attention. In this paper, we have theoretically devised and then experimentally validated a novel left-handed material (LHM) structure for multi-band operation. The proposed structure consists of a split-ring resonator (SRR) and defected ground structure (DGS) structure, which can provide arbitrarily positioned passbands by varying some geometrical parameters of the unit cell. The proposed dual LHM structure has been fabricated to demonstrate the applicability of the proposed unit cell. The experimental measured result is in good agreement with the simulation results. The designed device exhibits dual-pass band centered at 2.4GHz and 5.8GHz. The proposed LHM structure exhibits negative permittivity, and permeability in the targeted frequency ranges, which can be used in modern wireless communication systems for dual-band antenna application.

具有双左手特性的双波段左手材料的设计

为了提高信息能力，适应现代科学技术的快速发展，设计具有宽带多频谐振特性的左手材料受到了人们的广泛关注。在本文中，我们从理论上设计了一种新的左手材料(LHM)结构，并进行了实验验证。该结构由劈环谐振器(SRR)和缺陷接地结构(DGS)组成，通过改变单元胞的某些几何参数，可以提供任意定位的通带。所提出的双LHM结构已被制作，以证明所提出的单元电池的适用性。实验测量结果与仿真结果吻合较好。设计的器件具有以2.4GHz和5.8GHz为中心的双通带。所提出的LHM结构在目标频率范围内具有负介电常数和磁导率，可用于现代无线通信系统的双频天线应用。
