Abstract: In communication system the requirement of bandwidth enhancement is the most necessary requirement. This requirement of bandwidth increment can easily achieve the data rate of the system, so for further development of communication system higher bandwidth is required. Wireless communication already covered most of the frequency range till five giga hertz. In fractal technique structure which is similar in shape are designed for the similar nature of the radiation to increase the radiative power. By fractal radiation area can be increased, is used to achieve the bandwidth of the signal. By fractal technique size of the antenna can also be reduced for miniaturization of the device which is going to be developed. In this paper a different rectangular antenna is presented, consists of dual properties, is fractal and defected ground. This paper shows simulated result and designed hardware result and also shows the comparative result of these. In defective one rectangular slot has been introduced. A higher bandwidth rectangular antenna has been simulated and designed and a comparative analysis of simulated and hardware results compared and analyzed. Simulation done by considering 4 GHz as center frequency. The easily available material FR-4 is used for simulation as well as hardware design. In this substrate thickness will be 1.6mm. Return loss of the given design is achieved less than -10db for almost 11GHz. In future the many applications will use this range of frequency. The value of VSWR is also achieved less than two for 3GHz to 14GHz. Simulation of this design is done by HFSS software. The ground plane is also modified for enhancement of bandwidth.
