本文提出了一种适用于无线局域网（WLAN）应用的新型高增益双频天线，覆盖IEEE 802.11a/b/g频段。该天线由叉形单极子、矩形环和小型化矩形贴片组成。天线的背面辐射被矩形金属有效地反射回来，因此在低频段和高频段分别获得了6.2和10.4 dBi的最大增益。对回波损耗、辐射方向图和关键设计参数也进行了详细的研究。仿真和实测结果表明，该天线是一种较好的双频无线局域网远程通信解决方案。
A novel high-gain, dual-band antenna covering IEEE 802.11a/b/g bands is presented in this letter for wireless local area network (WLAN) applications. The antenna is composed of a fork-like monopole, a rectangular ring, and a miniaturized rectangular patch. The backside radiation of the antenna is effectively reflected back by a rectangular metal, so maximum gain with the values of 6.2 and 10.4 dBi are achieved in the lower and higher frequency band, respectively. The return loss, radiation pattern, and the critical design parameters are also investigated in detail. Simulated and measured results verify that the presented antenna is a good solution for dual-band WLAN long-distance communication applications.
