The error behavior of FIAFTA against planar near-field measurement errors in comparison with the traditional technique employing the two dimensional Fast Fourier Transform (2D FFT) has already been performed.
These modes can be deduced by filtering the planar near-field measurements by a 2D low-pass filter as shown in the Figure 5.
One way to obtain this kind of information is through the use of planar near-field measurements.

The combination of the antenna rotation and linear probe motion yields planar near-field data collected on concentric rings, with data points lying on radial lines.
A 2 m reflector that requires a 3 m X 3 m X-Y scan takes approximately two hours to test eight ports at 36 GHz using a NSI 300V-12 X 12 planar near-field scanner with a 20-inch per second (ips) scan axis and a competitive receiver at a single frequency.
The MI-3630 system is a planar near-field measurement system comprised of a precision planar (X-Y axes) scanner, near-field probe, two-axis position controller, and workstation computer and software.
Planar near-field (PNF) antenna measurements are appropriate for medium and high gain antennas and ideally require measurements on an infinite plane.
