Abstract: One of the typical problems of antenna farm analysis is the characterisation of the source antennas. Two typical approaches are followed and are both available within EAML: use of the antenna pattern (sampled on as Spherical Wave Expansion) and use of equivalent currents on a suitable equivalence surface. In both cases the main issue is to obtain an accurate and suitable model from simulated or measured data, which are intrinsically associated to different boundary conditions that those seen by the antenna installed on the platform. A typical example is that of a small antenna measured in "free" space that is installed on a rather large ground plane. Several approaches have been developed during the EAML study to overcome these problems.
