High Fidelity Modeling of 30m Near-Field Cassegrain Antenna in X-band

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.
