In today’s wireless communication, there has been an increasing need for more compact, portable and wideband radiators. There is a need to evolve antenna designs to minimum size which can be used in many practical applications in modern 2G, 3G, LTW, WiFi and WiMax wireless communications systems. Fractal antenna is one such antenna which is irregular in shape and it is mainly used for wireless applications. Thus, the objective is to design a novel fractal geometry which exhibits self similarity property and can be confined to space. The new proposed fractal antenna is designed in such a way that it can be operating at a frequency of 2.4GHz. This structure is built up through replication of a base shape, improving antenna performance. The purpose of this project is to explore fractal elements antennas through simulation and design experimentation. In the proposed approach, simulators are carried out using FEKO simulator 6.1 and the results are compared with the existing structures of monopole and Koch fractal. The design is implemented in planar structure also to improve its characteristics when compared to the wire monopole.
