A new method recently developed for planar nearfield broadband phaseless antenna measurement is adapted to work with a reduced set of points. The method is an extrapolation of the conventional off-axis holography in which a frequency sweep is made at each point of the acquisition grid, and the phase is retrieved simultaneously for all the frequencies by filtering the hologram in the time-domain. As...
A new efficient method for broadband antenna characterization from phaseless acquisitions in the frequency-domain (FD) is presented. The phase-retrieval technique is based on an extrapolation of the off-axis indirect holography. In common with the conventional approach, the power of the interferometric field of the antenna under test (AUT) and a reference antenna, whose field is known in advance,...
