Abstract: This paper describes the design of a modified Sierpinski fractal antenna with circular slots. The antenna is designed in such a way that makes it is suitable for upper UWB frequency applications. The antenna size is 30x30 mm2 and iterations performed till the second iteration. The antenna element is fed through a 50-ohm microstrip line (MTL). It is printed on the substrate FR4- epoxy. The antenna is designed for a frequency range of 2.5GHz to 15GHz. The simulated output shows that the designed antenna operates in multiband frequencies. The resonance frequencies appeared at 5.2GHz, 9.4GHz and 10.1GHz for the second iteration. The output is simulated on Ansoft HFSS (High-Frequency Structure Simulator).
