Abstract

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.
