Abstract

"In this paper a genetic algorithm is used in the design of a linear antenna array, aiding the designer to find the best antenna for his application. The designer indicates the number of elements of the set, the direction of the main lobe, the side lobe level, and the half-power beamwidth. In this methodology the objective function takes into account the amplitudes and phases of the feeding currents, and the position of each of the elements of the array simultaneously. With this approach, the optimization process covers a larger search space, allowing the designer to achieve a higher number of feasible solutions. Some examples illustrate the potential of the genetic algorithm applied to antenna array designs."
