This paper presents a multiband miniaturized fractal antenna designed and fabricated based on Koch Fractal geometry. The proposed antenna adopts 2-iteration Koch fractal structure fabricated on FR-4 epoxy substrate, with a overall size of 29.6x35.7x1.6mm3 .The Koch fractal antennas (iteration -0,1,2) are simulated over the frequency range (1-12GHz ) using ANSYS HFSS software to analyze the radiation characteristics in terms of Return loss, VSWR, Gain and Bandwidth .All the 3 antennas are exited using 50 ohms micro strip feed line. The simulation results of the 2-itration Koch MPA produces better radiation characteristics with 7.74% of Miniaturization. so it is fabricated ,which shows 4 resonances at at 2.7 GHz,6.6 GHz,8.4 GHz, and 11.3 GHz center frequencies.. The proposed antenna validated using VNA and the resonating bands covered by this antenna are (2.4-2.77 GHz), (6.5-6.682 GHz) (8.1-8.42 GHz), (10.8-11.4 GHz ) which proves that it is suitable for Wi-Fi, C and X band wireless communications. More over the measured results of the proposed antenna found to be in very good matching with its numerical simulated results
