Comparison of Near-Field Phaseless Measurements Using Multiple Planes

In this paper, an improved near-field (NF) phaseless measurements approach based on the iterative Fourier technique (IFT) is proposed using a priori information on the antenna under test (AUT) aperture and magnitude-only NF data on three scanning planes at different distances. Based on the compared results from some other methods such as traditional two-scans technique and two-scans technique with a priori information on AUT aperture, it validates that the proposed approach exhibits the characteristic of low efficiency but high accuracy.
