A circular multiband fractal antenna is presented here.The fractal antenna has the multiband operation due to the self-similar property in fractal geometry. Sierpinski Gasket approach is used to make the circular fractals. The antenna consists of a circular patch with a line feed that is designed to radiate at 3.5 GHz. Antenna is designed on FR4 glass epoxy substrate with parameters like thickness 1.6mm, dielectric constant 4.4. Fractal geometry helps to improved bandwidth, radiation efficiency and reduced size. The proposed antenna resonant frequencies are centred at 3.8 GHz, 4.8 GHz, 5.6 GHz, 6.3 GHz. Circular patch antenna is used as the basic geometry and 3 stages of iterations produced the proposed design. Radius of the base antenna is 25 mm. The simulated results for various parameters like return loss, radiation pattern etc have been presented . Designed antenna can be used for several wireless communication applications like WiMAX (5.2-5.5 GHz), C-band (6.95-7.4 GHz). The designed model is simulated using HFSS 13.0
