Abstract

This paper presents an innovative method for the design of a triple band meta-mode antenna. This unique design of antenna finds application in a particular frequency band of WLAN and WiMAX. This antenna comprises of a square complimentary split ring resonator (SCSRR), a coaxial feed, and two symmetrical comb shaped split ring resonators (CSSRR). The metamaterial unit cell SCSRR independently gains control in the band range 3.15-3.25 GHz (WiMAX), whereas two symmetrical CSSRR unit cell controls the band in the ranges 3.91-4.01 GHz and 5.79-5.94 GHz (WLAN). This design methodology and the study of the suggested unit cells structure are reviewed in classical waveguide medium theory. The antenna has a miniaturized size of only 0.213λ0 × 0.192λ0 × 0.0271λ0 (20 × 18 × 2.54 mm, where λ0 is the free space wavelength at 3.2 GHz). The detailed dimension analysis of the proposed antenna and its radiation efficiency are also presented in this paper. All the necessary simulations are carried out in High Frequency Structure Simulator (HFSS) 13.0 tool.

摘要

本文提出了一种用于设计三频段元模式天线的创新方法。这种独特的天线设计应用于WLAN和WiMAX的特定频段。该天线由一个方形互补分裂环谐振器（SCSRR）、一个同轴馈电和两个对称的梳状分裂环谐振器（CSSRR）组成。超材料单元SCSRR在3.15 - 3.25 GHz频段（WiMAX）独立获得控制，而两个对称的CSSRR单元在3.91 - 4.01 GHz和5.79 - 5.94 GHz频段（WLAN）控制频段。这种设计方法以及所建议的单元结构的研究在经典波导介质理论中进行了综述。该天线尺寸仅为0.213λ0×0.192λ0×0.0271λ0（20×18×2.54 mm，其中λ0是3.2 GHz时的自由空间波长），具有小型化特点。本文还给出了所提天线的详细尺寸分析及其辐射效率。所有必要的模拟均在高频结构模拟器（HFSS）13.0工具中进行。
