In this article, we present a novel ultrawideband (UWB) coplanar waveguide fed printed monopole antenna with fan-shaped structure. Its UWB-related performances are simulated and experimentally verified. The fabricated antenna occupies a small area, exhibits omnidirectional radiation pattern and good gains within the operating band, which illuminates the fan-shaped structure is also a good candidate for UWB antenna design. © 2012 Wiley Periodicals, Inc.
