Abstract

A double-negative metamaterial-inspired antenna is presented for mobile wireless applications. The antenna consists of a semi-circular radiating patch and a 3 × 4 hexagonal shaped metamaterial unit cell array in the ground plane. The antenna is fed with a 50 Ω microstrip feed line. The electric dimensions of the proposed antenna are 0.20λ × 0.26λ × 0.004λ, at the low-end frequency. The proposed antenna achieves a -10 dB impedance with a bandwidth of 2.29 GHz at the lower band and 1.28 GHz at the upper band and can operate for most of the mobile applications such as upper GSM bands, WiMAX, Bluetooth, and wireless local area network (WLAN) frequency bands. The focused novelties of the proposed antenna are its small size, multi-standard operating bands, and electromagnetic absorption reduction at all the operating frequencies using the double-negative metamaterial ground plane.

摘要

本文提出了一种用于移动无线应用的双负超材料激励天线。该天线由一个半圆形辐射贴片和接地平面中的一个3×4六边形超材料单元阵列组成。天线通过50Ω微带馈线馈电。在低频端，所提出天线的电尺寸为0.20λ×0.26λ×0.004λ。所提出的天线在较低频段实现了-10 dB阻抗带宽为2.29 GHz，在较高频段为1.28 GHz，并且可以在大多数移动应用中工作，如上部GSM频段、WiMAX、蓝牙和无线局域网（WLAN）频段。所提出天线的重点创新之处在于其尺寸小、多标准工作频段以及使用双负超材料接地平面在所有工作频率下降低电磁吸收。
