It has been found that designing an antenna using the properties of fractal geometry results in an antenna that resonates at multiple frequencies. In this work two designs of fractal antennas have been studied. The designs are simulated using 4NEC2 software. The antenna is designed in XZ plane with design frequency equal to 400MHz and 800MHz and results are analysed considering four antenna parameters VSWR, reflection coefficient, gain and resonant frequency. The simulation results show that the Triangular KOCH Curve Design when given iteration, two times it shows multiband behaviour whereas the Serpinski gaskets design resonates at single frequency. Also the Koch Fractal technique that has been applied to the antenna structure reduces the length of the elements. The results show that the designed Koch Curve antenna is suitable for wireless applications.
