Abstract
In this article, a novel miniaturized tri-band monopole antenna for WLAN/WiMAX applications is presented and investigated. The proposed antenna consists of a horizontal H-shaped patch, an L-shaped open end stub, and a deformed inverted T-shaped strip. The patch attached to the 50-› feed-line through a matching line can increase the bandwidth of the proposed antenna. The bandwidths under the condition of jS11j • i10dB of the proposed antenna are 340MHz (2.4{2.74GHz), 340MHz (3.41{3.75GHz), and 640MHz (5.24{5.88GHz), respectively, indicating this antenna is suitable for WLAN (2.45{2.4835, 5.16{5.35, and 5.725{5.85GHz) and WiMAX (2.5{2.69, 3.4{3.69, and 5.28{ 5.85GHz) applications. The antenna is successfully simulated and measured. Experimental results show that the proposed antenna with compact size of 30£20£0:8mm 3 has nearly omnidirectional radiation characteristics and stable gains across all the operating bands with a simple structure.
