Abstract In this paper, a planar tab monopole antenna is presented for broadband antenna design for ultra‐wideband (UWB) applications. The impedance bandwidth of the antenna is improved by adding slit in one side of the monopole, introducing a tapered transition between the monopole and the feed line, and adding two‐step staircase notch in the ground plane. The proposed antenna has a small size of 16 × 19 mm, and provides ultra‐wide bandwidth from 2.8 to 22 GHz in order to satisfy the requirements of the current and future wireless communications systems. Low VSWR level and good radiation characteristics are obtained. Additionally, an inverted U‐slot is embedded in the proposed antenna to avoid interference between UWB and WLAN systems. © 2006 Wiley Periodicals, Inc.
