Abstract: For the pattern synthesis of antenna arrays by using genetic algorithm, it is important to select a proper objective function, which greatly influences the result and efficiency of the algorithm. In this paper, some kinds of objective functions used in the pattern synthesis are introduced and compared. A general objective function is presented, which can be used in many kinds of pattern synthesis problems. Meanwhile, the influence of weight factor in the objective function is studied. -
