Abstract A new design of the printed omnidirectional antenna for applications in 2.4/5‐GHz dual‐WLAN‐band access points is proposed. The antenna consists of a conventional collinear antenna for 2.4 GHz operation and two U stubs for 5 GHz operation. The two U stubs are located near the points where the maximum currents at about 5.5 GHz occurring on the strips of the collinear antenna and arranged back‐to‐back in the same phase for achieving better antenna gain. Detailed analyses of the U stub on the impedance matching over the 5 GH band is presented. A prototype with good omnidirectional radiation across the 2.4/5‐GHz WLAN bands is demonstrated. © 2008 Wiley Periodicals, Inc.
