Abstract Miniaturized microstrip patch antennas based on fractal geometry operating at triple bands and a single wideband in ultra‐wideband (UWB) (3.1–10.6 GHz) frequency range are proposed here. Three iterations of a circular radiating patch and the high relative permittivity of the substrate are used to radiate the proposed antenna at 3.9, 6.25, and 9.0 GHz in UWB. Size reduction is compared with previously reported triple band antennas. The bandwidth of the designed antenna is enhanced and triple bands of the designed antenna are merged into a single wide band, from 3.65 to 10 GHz, by normalizing the parameters of the radiating circular fractal structure for the UWB applications. Comparison between antennas for the UWB applications in literature and proposed antenna is presented.
