Abstract
This paper presents a novel electromagnetic optimization technique based on the use of an adaptive genetic algorithm for the synthesis of antenna arrays by optimizing complex coefficients to best meet a desired radiation patterns. The dynamic control of genetic algorithm setting parameters or control parameters such us: mutation or crossover probabilities has been realized using the well known performances of fuzzy set theory. A fuzzy controller is designed to adjust on line the control parameters of genetic algorithms depending on the measure of the population diversity. The presented optimization algorithms were previously checked on specific mathematical test function and show their superior capabilities with respect to the standard version (standard genetic algorithms). Included examples demonstrate the best performances obtained while implementing fuzzy genetic algorithms (FGAs).
