A novel compact ultrawideband planar antenna fed by a microstrip line is proposed. The proposed antenna consists of a rectangular patch and a defected ground plane with a semicircular notch and two stubs. The modified ground plane is used to achieve the wide impedance bandwidth. The measured results show that the antenna has a bandwidth 2.1–2.6 GHz and 3.3–20 GHz for S 11 < −10 dB. The proposed antenna exhibits the omnidirectional radiation patterns and appreciable gain across the operating band. © 2012 Wiley Periodicals, Inc.
