We deal with the problem of extracting the maximum amount of information on an aperture field Ea from field measurements on a domain DI, with a priori information on the aperture field itself. Since collecting the information on DI is performed by means of field probes occupying different spatial positions, the problem at hand requires determining, as a function of the properties of the employed probes,...
This paper presents a phaseless near-field antenna characterization algorithm exploiting an "effective" representation of the aperture field and of the plane wave spectrum (PWS), based on the prolate spheroidal wave function (PSWF) series expansion. Indeed, as long as aperture antennas are involved, due to the Fourier transform relationship connecting aperture field and PWS, the PSWFs span...
