Cantor Fractal Linear Antenna Array with Koch Fractal Elements


Abstract:Cantor fractal linear array, with ‘101’ generator from second stage of growth, is analyzed here with two types of current amplitude excitation coefficients (Dolph and Fractal). The Koch fractaldipole element with 2nd iteration and θ=60o will be used here as the array elements. Kaiser-Bessel window will be used as the generating function, to calculate the fractal amplitude excitation coefficients. The benefit from using fractal antenna element in the design of fractal antenna array will be clearly deduced from the results. The radiation pattern and impedance were calculated by using software package MATLAB version 7.6 (R2008a) and software package 4NEC2 respectively.
