Abstract :
This paper deals with the design of non-uniform circular phased arrays for maximum side lobe level reduction during scanning. We present a pattern synthesis method of non-uniform circular antenna arrays for simultaneous reduction of the side lobe level and pattern distortion over different scanning ranges. The method of genetic algorithms is used to determine an optimum a set of weights and antenna element separations that provide a radiation pattern with maximum side lobe level reduction over different scanning ranges. Simulation results show that design of non-uniform circular antenna arrays using the method of genetic algorithms provides a considerable side lobe level reduction although the beam direction is steered over wide scanning ranges
