A comparison of the planar, spherical and cylindrical near-field techniques was completed at the National Institute of Standards and Technology (NIST) for a Ku-band Cassegrain reflector antenna. This paper discusses the measurement results for the near-to-far field measurements. We also report on the sources and magnitudes of the uncertainties for the on-axis gain and patterns of the three near-field techniques. We conclude that the results from the three different near-field methods agree within the regions of validity to the stated uncertainties.
