Synthesis of antenna arrays using genetic algorithms

Abstract:

The synthesis of the radiation pattern of linear antenna arrays is an interesting problem in radiating systems. When the synthesis of antennas is subject to many restrictions the problem is very complex and becomes difficult to solve by classical optimization techniques because they are vulnerable to local minima problems. One relatively novel technique which could be used for the synthesis antenna is the use of Genetic Algorithms. In this article two methods for the synthesis of the radiation pattern of a linear array antenna based on GAs are presented. With these techniques it is possible to synthesize a radiation pattern specified by shaped beams and nulls in given directions. Results for differents cases are presented.
