This work provides the comparison of difierent methods for the experimental determination of the phase center location of an antenna. The phase center position is determined by means of measured data obtained with a planar scanning system and computed with difierent methods: a least-squares flt method with and without weighting coe-cients and a directivity-based plane wave spectrum (PWS) analysis method. A study of the phase center position for difierent microwave antennas is provided. The results of the difierent methods are presented and compared, along with the confldence interval of the phase center values due to the uncertainties of the acquisition system.
