Abstract

This paper presents nulling in offset parabolic reflector with cluster array feed employing a genetic algorithm (GA). Unlike the conventional GA which uses random initial phase and amplitude settings, initial settings of one of the individuals is chosen as binary representation of conjugate field matching vector. We consider the pattern nulling problem in circularly polarized case which is widely used in most satellite and other terrestrial communication systems.
