In this paper, we apply a recently developed 3D source reconstruction algorithm to perform antenna diagnostics on a planar array configuration. The test case is a planar X-band slot array measured in a spherical near-field facility and two slots were intentionally covered during the measurement campaign to test the performance of the algorithm. These measured data have previously been analyzed in [1] using two different methods for planar back-projection. For the purpose of comparison, results obtained with a planar reconstruction method based on conversion of spherical waves are also presented.
