This letter presents a design of a novel ultrawideband (UWB) circular fractal monopole antenna with a six‐petaled flower pattern. The coplanar‐waveguide‐fed technique and fractal concept have been used to achieve UWB characteristics. The size of the proposed antenna is 43 × 51 mm 2 with a flower‐shaped circular patch radius of 15 mm. The proposed antenna exhibits UWB characteristics from 2.46 to 13.46 GHz, which corresponds to a fractional bandwidth of 138%. The measured radiation pattern of the proposed antenna is nearly omnidirectional. © 2013 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:1792–1795, 2013
