In this letter, a novel microstrip line‐fed printed monopole antenna for ultra‐wideband (UWB) short‐range wireless communications is proposed. The proposed antenna consists of a trapezoidal‐shaped patch with two elliptical‐shaped cuts from its edge forming a bell‐shaped cut. Experimental results shows that the designed antenna operates over impedance bandwidth 3.2–11.4 GHz for return loss S 11 < −10 dB, which almost covering the UWB frequency bandwidth. Moreover, the antenna has a good omnidirectional radiation patterns in the H ‐plane with good gain flatness over the frequency range of interest. The antenna transmission characteristics at different receiving angles are also measured. By embedding a simple narrow U‐shaped slot in the radiating microstrip patch, a notch in the frequency band of 5.0–6.0 GHz is obtained. The proposed antenna is considered a good candidate for UWB short‐range wireless communication systems avoiding the interference of the existing wireless systems. © 2011 Wiley Periodicals, Inc.
