Design of aperiodic planar arrays for desirable isoflux radiation in GEO satellites

The design of an aperiodic array is presented in this research. This design of aperiodic array considers the reduction of the side lobe level and the isoflux radiation requirements for GEO (Geostationary Earth orbit) satellite applications. In this way, it is considered an optimization of positions of the antenna elements and levels of amplitude excitation. For the optimization problem, the well-known method of Genetic Algorithms (GA) is utilized. The obtained results show the proper performance of the array factor to provide the isoflux radiation and low side lobe level. Depending on the performance requirements, the design of the aperiodic array could lead the satellite hardware to be reduced significantly even more that results presented in the literature.
