In this article, a novel inscribed square circular shape fractal antenna is proposed for UWB applications. The proposed antenna has been designed on FR4 substrate ε r = 4.3, h = 1.53 mm with the diameter 18.4 mm. The CPW‐feed technique and the fractal concept have been used to achieve the ultra‐wideband impedance matching and compact size. The experimental result of proposed fractal antenna exhibits the ultra‐wideband characteristics from 3.01 to 15.0 GHz at VSWR 2:1 corresponds to 133.149% impedance bandwidth. The proposed antenna has also been studied experimentally with respect to each iteration. The measured radiation pattern of fractal antenna is nearly omnidirectional in azimuth plane and dumble shape in elevation plane. This antenna is useful for UWB communication System. © 2011 Wiley Periodicals, Inc. Microwave Opt Technol Lett 53:1079–1083, 2011; View this article online at wileyonlinelibrary.com.
