Application of the SWE-to-PWE antenna diagnostics technique to an offset reflector antenna
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.
