Electrical and mechanical errors in an antenna may seriously affect the antenna's performance. Although their presence is usually detected by anomalies in the antenna's far-field pattern, their identification is normally possible only through an analysis of the antenna's extreme near field. The reconstruction of the extreme near field on the basis of near- or far-field measurements is thus an essential step in antenna diagnostics.
