The ridged waveguide polarizer is considered as the better way to get right-hand and left-hand circular polarization in the antennas of telecommunications satellites. In fact, it is a system of three ports used to feed a square waveguide antenna in order to achieve high purity in the right-hand and left-hand circular polarization. Obtaining a great purity of polarization results by the addition from screw from adaptation and blades from correction. A solution with this problem is obtained by the optimization of dimensions of the various ridges. The object of paper consists in determining optimal dimensions of the ridges of the polarizer by using the "Genetic Algorithms".
