Abstract :
The purpose of this paper is to create a link with a flat received signal level, which is not depend on elevation angle between LEO satellite and earth receivers. This problem is solved using beam shaping of separated turnstile antenna for satellite employing a real coded Genetic Algorithm (CA). We have Introduced a special strategy to improve the results of the algorithm using the concept of derivation in cost function (CF).
