Abstract

An omnidirectional dual-band planar dipole-array antenna suitable for application in 2.4/5.2-GHz WLAN access points is presented. The dipole-array antenna is a linear array and comprises three back-to-back dipole elements with the first two elements operating in the 5.2-GHz band and the third one operating in the 2.4-GHz band. The proposed array antenna is narrow in width (12 mm in this design), and good omnidirectional radiation with gain variations less than 2 dBi for both the 2.4- and 5.2-GHz bands is obtained. In addition, the antenna provides enhanced antenna gain (about 3.7–4.1 dBi) for frequencies across the 5.2-GHz band, and good antenna gain (about 2.2–2.8 dBi) is also obtained across the 2.4-GHz band. © 2003 Wiley Periodicals, Inc.
