In this article, an octagonal monopole antenna embedded with three slits in the ground plane is proposed. Its ultra‐wideband (UWB) operation within the required frequency (3.1–10.6 GHz) is fine tuned by embedding a small rectangular slit at the top center of the ground plane, whereas the band‐notch function is achieved by embedding two symmetrical L‐shaped slits located at both sides of the ground plane. The gain and time‐domain characteristics of this antenna show that it is applicable to any wireless communication system that requires a stable signal transmission in the 5‐GHz notch‐band‐excluded UWB. © 2008 Wiley Periodicals, Inc.
