In this paper, presenting the design and analysisof Modified Circular Fractal Antenna (MCFA) for S, Cand X- band applications. Used the defined range of Sband is 2GHz-4GHz, C-band is 4GHz-8GHz and X-band is8GHz-12GHz. S-band communication antennas haveapplication in weather, tracking, and microwave oven. Cband antennas are useful in telecommunication, satellitecommunication and X-band is useful in radar applications.The proposed antenna has been implanted on FR4-epoxysubstrate with the dielectric constant of 4.4 and height of1.6 mm. Circular fractal antenna exhibits all requiredparameters that depends on the sizq and feed line positionof the circular patch. The antenna has also been fabricatedwith optimized dimensions and then tested. The proposedantenna is fed by a microstrip line feed. The proposedantenna has been designed and simulated by HFSS vs 13.0(High Frequency Structure Simulator). The variousantenna parameters such as return loss, VSWR, gain andradiation pattern has been calculated. This proposedantenna operates at five different frequencies 2.87GHz,6.39GHz, 6.89GHz, 8.00GHz and 8.51 GHz. The vectorNetwork Analyzer (VNA) of proposed antenna is used forthe measurement of return loss, VSWR. The simulatedand measured results are compared and are found to be agood relative values with each other. Small in size,reduction in construction costs are the advantages ofproposed antenna.
