Synthesis of linear and planar antenna arrays using genetic algorithms

Two particular methods for the synthesis of the complex radiation pattern of a linear and planar array based on genetic algorithms (GAs) are discussed. First we present a combination of Schelkunoff´s method and GAs for linear arrays with arbitrary radiation patterns, then we consider the synthesis of planar arrays with rectangular cells jointly with a penalty method in order to improve the results. There is good agreement between the desired and calculated radiation patterns.
