In this paper, three different antenna diagnostics techniques are compared for the case when the input far-field data represent only few complete cuts or a two-dimensional grid with a limited angular sector. The techniques are applied to several different antennas: a high-gain offset reflector antenna, a large slotted waveguide array, and a small slotted waveguide array with shaped excitation. Systematic investigation is carried out to provide a relation between the number of the input antenna cuts or the size of the angular sector and the quality of the reconstructed equivalent currents and extreme near fields.
