Synthese d'antennes microrubans en reseaux non periodiques a partir de modeles equivalents. Optimisation par I'algorithme genetique

摘要

The majority of the methods used for the radioelectric characterization of the microstrip antennas require long and tiresome numerical calculations in general. The goal of this study is to use simple and precise equivalent electric models, making it possible to take account of the whole of the geometrical, electric and technological characteristics of the antennas and their feed. From the equivalent model of the transmission line, the synthesis of microstrip antennas in non-periodic arrays for various configurations of feed by micros-trip line is elaborate. The method of synthesis of these arrays is developed by employing a stochastic technique of optimization based on the genetic algorithm.
