摘要

本文介绍并讨论了一种由四个复合左右手(CRLH)超材料单元单元组成的印刷多频带单极子天线。采用这种 CRLH 超材料加载大大缩小了天线尺寸,提高了天线增益。所提出的天线尺寸小巧,仅为 30×25×1.6mm3,可在 2.5、4.1、5.25 和 6.1 GHz 频段多频段工作,反射系数优于-10dB,属于实用无线频段。该天线已经制作完成并通过了实验测试,测量结果与模拟结果一致。

A Compact Multiband Metamaterial-Based Antenna for WLAN and WiMAX Applications
A printed multiband monopole antenna consists of four composite right/left-handed (CRLH) metamaterial unit cells is presented and discussed in this paper. Employing such CRLH metamaterial loadings have considerably reduced antenna size and increased antenna gain. The proposed antenna has a compact size of 30×25×1.6mm3 and provides multiband operation at 2.5, 4.1, 5.25 and 6.1 GHz, with reflection coefficient of better than -10dB which are within the practical wireless frequency bands. The proposed antenna has been fabricated and experimentally tested and good agreements between measured and simulated results can be observed.
