摘要：In this paper, a new modified printed Koch Island Fractal Patch Antenna (KIFPA) is studied. The conception of such antenna is based on the combination of different techniques. The first, concerns the fractal geometry of the patch, while the second comprises modified ground-plane. The patch is etched according to Koch Island geometry with different iteration number (n = 1, 2 and 3) as inductive loading. It is proximity fed by a 50Ω micro strip line. The proposed antenna operates in the frequency band [6.03–12.62 GHz] with 70.7% for S 11 ≤ −10 dB. The antenna gain and radiation patterns within the operating band are simulated. The design was performed using the CST Microwave Studio Software and the results are presented, compared and discussed. Finally, the proposed antenna is fabricated and the reflection coefficient parameter is measured to validate simulation results.
