Simultaneous Control of Side Lobe Level and Beamwidth in Planar Array Antenna using Restricted Search Evolutionary Algorithms

Present article investigates a novel method of pattern synthesis in planar array using restricted search Evolution algorithms. Multiple objectives of Side Lobe Level and beamwidth control have been transformed in single objective using weighted sum technique. In said optimization process excitation amplitude weights along with uniform inter-element spacing respectively have been considered as optimization parameters. Effectiveness of the proposed method has been illustrated through design and validation of 9×9 planar array configuration.
