Abstract

In this paper, Koch curve fractal antenna is proposed for wireless applications. The antenna has been designed by increasing the perimeters of triangular shape patch by using self-similarity property. Number of iterations by the designing Koch snowflake for different resonant frequency, are given. The proposed antenna is designed to operate at Wi-MAX frequency from 3.4 GHz -3.69 GHz and C-Band applications in 2.8 GHz-6.4 GHz frequency range. The proposed antenna is fed by a 50-Ω microstrip line and fabricated on a low-cost FR4 substrate having dimensions 33.5(L) × 28.5(W) × 1.6(h) mm³ with □_r=4.4 and tanδ= 0.025. The antenna shows acceptable gain with nearly omni-directional radiation patterns in the frequency band for wireless applications.
