A printed diversity dipole antenna suitable for applications in wireless local area network (WLAN) access points in the 2.4 GHz (2400–2484 MHz) and 5.2 GHz (5150–5350 MHz) bands is presented. The antenna comprises two stacked printed dipoles placed back‐to‐back. Each stacked dipole consists of two larger dipole arms for 2.4‐GHz band operation and two smaller dipole arms for 5.2‐GHz band operation. In addition, the proposed antenna can provide spatial diversity, because the obtained radiation patterns of the two stacked dipoles are directional in two complementary half spaces and the access point can thus switch between the two stacked dipoles for WLAN communication with maximum signal strength. Experimental results of a constructed prototype are presented. © 2003 Wiley Periodicals, Inc.
