Linear Antenna Synthesis with a Hybrid Genetic Algorithm

An optimization problem for designing non-uniformly spaced, linear arrays is formulated and solved by means of an improved genetic algorithm (IGA) procedure. The proposed iterative method aims at array thinning and optimization of element positions and weights by minimizing the side-lobes level. Selected examples are included, which demonstrate the effectiveness and the design flexibility of the proposed method in the framework of electromagnetic synthesis of linear arrays.
