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.
