Abstract :
Here we address some of the issues faced by antenna engineers when testing active antennas. We review some features of relatively wideband phased arrays and report on how MI Technologies has dealt with the issue of measuring the effective isotropic radiated power (EIRP) and antenna patterns by use of the spherical near-field scanning technique. We take as an example the test methodology of the SAMPSON radar antenna.
