ABSTRACT
The multi-objective design of concentric ring antenna arrays for isoflux radiation for Geostationary Earth Orbit (GEO) and Medium Earth Orbit (MEO) satellites is presented in this paper. This design of concentric ring antenna arrays considers the optimization of the spacing between rings and the amplitude excitation across the antenna elements in order to generate the trade-off curves between the side lobe level (SLL) and the isoflux mask error. In order to use fewer levels of excitations to diminish the hardware complexity, a concentric excitation is considered across the antenna array. Simulation results applying a differential evolution multi-objective (DEMO) optimization method are provided in this document. Furthermore, an analysis of the trade-off curve between the SLL and the isoflux mask error is achieved.
