The Antenna Design Framework -ElectroMagnetic Satellite is an antenna design system offering a wide palette of modeling tools aimed at covering engineering needs from the early feasibility studies to the last performance-verification stages of flight hardware. A few key ideas have been central to its development, focusing on the overall engineering process rather than on individual modeling steps. This has led to a modeling architecture that offers a very high degree of modularity, scalability, and flexibility. Some practical examples are used in the discussion to illustrate these points.

This paper discusses about design, analysis and optimization aspects of metasurface antennas. The design procedure of metasurfaces for the realization of shaped beam antennas and application examples are presented. For the fast analysis and for a suitable use in an optimization loop a customized efficient full wave tool has been developed within the 3DAMxLAD module of ADF-EMS (Antenna Design Framework - Electromagnetic Satellite). © 2013 IEEE

A 30 m Near Field Cassegrain antenna has been accurately simulated using a real 3D acquisition of the reflectors surfaces. Even though no kind of symmetry or approximation can be exploited, Antenna Design Framework (ADF) software is able to model this problem at 1.5 GHz with a full-wave approach and even at 10 GHz with a mixed-methods approach.
