INVESTIGATIONS ON THE RADIATION CHARACTERISTICS OF CANTOR FRACTAL ARRAY

Abstract

Fractal geometry proved to have wide applications in electromagnetics with their frequency independent and multiband characteristics. Of the several typical geometries Cantor set has close analogy with a simple linear array. Hence for this paper antenna array whose geometry obeys the Cantor fractal representation is considered. Investigation based on E field radiation patterns are performed and compared with that of conventional uniform linear array (ULA). A relation between the fractal size and its radiation characteristics like its maximum side lobe level, beam width are inferred from the radiation curves. The similarity between the conventional and the fractal arrays are discussed..
