This project deals with a multi - band fractal based square micro- strip patch antenna is designed. FR4 substrate having thickness of 1.58 mm is used as substrate material for the design of proposed antenna and micro-strip feed line provides the excitation to the antenna. The antenna operating frequency range is from 1 to 10 GHz. The proposed antenna is designed and simulated by using the Ansoft HFSS V15 (high frequency structure simulator) software. A fractal is a geometric shape containing detailed structure at arbitrarily small scales, usually having a fractal dimension strictly exceeding the topological dimension. Microwave antenna and passive circuit designers have to meet the ever encountered challenges to produce components with miniaturized size and multi band operation. These geometries have two unique features: the space filling and the self-similarity. For more than two decades, these features have opened the novel and essential techniques for the design of the microwave antennas and passive circuits. Furthermore, fractal-based structures offer an additional epoch of optimizing design mechanisms. This is an analytical study through which we design a chip and study the different parameters such as S-parameters, VSWR and other graphical plots. HFSS (High-frequency structure simulator) is used for the simulation of various patch antennas and for observing the parameters of the antenna. HFSS is the software used for the simulation and modelling of the antenna.
