Abstract :
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 "at best", namely with the least possible number of functions, the space of finite-supported aperture fields corresponding to "essentially" finite-supported PWS\´
