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 notchband-excluded UWB.
