THEORETICAL-ANALYSIS OF A FRACTAL SURFACE RADIATION

We compare, in this paper the far field radiated by two fractal distri butions of current. The first one is obtained by a fractal cut followi ng the Cantor arrangement the second one keeps the length of each prev ious current element, but modifies the distance between the elements w hich is now taken as a constant. We establish the analytical formulati ons of the far field at any step n of the Canter set. Then, we extract the array factor and we analyse and compare the following properties : convergence of the radiation pattern, wide of the main lobe, side lo bes level and directivity.
