Abstract
Fractal antenna array generation is depending on never ending pattern design methodologies. Concentric elliptical ring sub-array (CERSA) generator is one of the deterministic geometric design methodologies for the generation of polygon and narrow beam fractal array antennas. This paper presents modified CERSA design methodology for the improved array factor characteristics than the original or unmodified version. This modified version mainly includes insertion of the central antenna element on each sub-array of the considered fractal array and amplitude tapering. Rhombic fractal array antenna generated by CERSA have considered in this work, to demonstrate the proposed modifications. All corresponding results presented in this paper, simulated by the Scilab open and free source programming.
