Abstract

In this article, we have proposed a dual‐band antenna with U‐shaped open stub for wideband local area network (WLAN)/ultra wideband (UWB) applications. The designed dual‐band antenna consists of two semicircle radiating patches, a rectangular slot separating the two semicircles, one step for impedance matching, and coplanar waveguide (CPW) feeding. Two kinds of prototypes (CPW‐fed UWB antenna and the dual‐band antenna with U‐shaped open stub) are fabricated and measured. Parametric studies and radiation characteristics for the two antennas are presented. The designed antenna has the figure‐of‐eight radiation pattern, wide bandwidth, and negligible dispersion over the operating frequency band. © 2008 Wiley Periodicals, Inc.
