Fractal antenna, as name concerns, uses fractal i.e. structure does not change and repeat it when large focus has created upon it. This repetition feature of this antenna provides a great flexibility that it can be designed and can used in different frequencies. Fractal geometry has shown its potential in many fields of engineering and technology. In antenna engineering fractal geometry is very useful for performance improvement, in terms of gain and other things. This paper presents a modified fractal T-shape antenna meant for WiMAX applications. The simulation results of the proposed design show that the fractal shape gives better performance than that of existing one. Simulation outcomes also demonstrate that the anticipated design gives enhanced performance in stipulations of return loss. Simulation results show that the operating frequency of the proposed antenna is applicable for WiMAX applications.
