This paper presents a micro strip fractal antenna for the applications used in lower range of 5G milli-meter wave frequencies from 25GHz to 35GHz. Fractal antenna is fed with lumped port feed structure. The stepping fed is used to provide better antenna characteristics at the said frequency range. The proposed antenna uses fractal geometry which is self-similar in nature and can be used for wide band applications. The micro strip antenna is designed and simulated using hfss v15 with a substrate of Rogers RT duroid 5880tm with the thickness of 1.6mm and a relative permittivity of 2.2 and dielectric loss tangent of 0.0009. The size of the radiating patch is about 35mm X 40 mm and the ground plane is recessed in order to improve the total gain. The resonance frequency is set at 30 GHz such that it can be used for the lower band milli meter applications. This antenna creates the fractal geometry inside the patch with the shape of rectangular patches at twelve different places.
