Abstract
Recently, a phaseless near-field antenna characterization approach has been proposed. It exploits an "effective" representation of the unknowns, able to reduce the overall number of parameters to be sought for and with signicant beneficial effects on both accuracy and reliability. At the same time, on taking advantage of the a priori information on the scanning geometry through a non-uniform sampling of the near-field, beneficial effects are obtained on the stability of the inversion process, on the rejection of the environmental clutter and on significantly reducing the overall number of near-field phaseless measurements to be performed.Experimental results at 75 and 94GHz concerning the near-field phaseless characterization of millimetre-wave antennas are presented. The results results show the feasibility of phaseless antenna characterization also in the millimetre frequency range. The aim of this paper is to numerically point out the accuracy and reliability of the proposed algorithm, with particular reference to millimeter-wave applicationsI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
