“…Iterative methods between two scanning surfaces are also a possible solution, but the measurement time is increased and it is very sensitive to the initial guess and separation between surfaces (presence of local minimum). In [3] mean errors about -35dB where achieved by choosing the proper initial guess and separation between acquisition planes. Interferometry methods [4] or probe with multiple outputs [5] have also been tested in the literature.…”

In a previous paper a new referenceless measurement set-up based on a reference antenna was used for characterizing the radiation of antennas in the planar scanner [1]. The method is based on using a low-cost receiver to retrieve the amplitude and phase of the signal. This paper explores the limitations of the method for different geometries and implements a multiprobe electromagnetic compatibility measurement system. Once the amplitude and phase are recovered, diagnostic techniques can be applied and also near-field to near or far-field transformations to calculate the field at distances defined by standards. The results demonstrate the good accuracy of the method in comparison with traditional electromagnetic compatibility laboratories.
