The main aim of this paper is to upgrade MammoWave acquisition and appropriately extend the Huygens Principle (HP) algorithm for allowing a 3D imaging reconstruction.\nThe MammoWave device contains a cylindrical hub and two antennas, which are positioned\nat the same height and connected to a 2-port vector network analyser (Cobalt C1209, Copper\nMountain, Indianapolis, IN). The two antennas can rotate azimuthally all around the object to\nbe imaged. Measurements are performed by recording the complex S21 in a multi-bistatic fashion.\nIn this paper, we have achieved a phantom-based investigation using a multi-quote scanning\nprocedure via MammoWave operating at a 1–6.5 GHz frequency range. Specifically, a cylindrical\nphantom possessing a radius of 5.5 cm and height of 13 cm is constructed and a 3D structured\nvolumetric flask with a spherical bottom (radius 1.75 cm) is used as inclusion. The materials\nand mixtures used in the preparation of the phantom have a contrast of 5 in dielectric properties. Next, measurements at planes along the z-axis are performed and multi-quote data are\nused in a modified version of the HP-based algorithm via superimposition theorem. The complex\n6 × 15 × 80 S21 is processed allowing 3D imaging reconstruction; our results clearly show the 3D\nvisualisation of the detected inclusion at multiple planes. In more detail, we verified that the\ndimension of the detected inclusion varies in the different planes of visualisation, accordingly to\nthe spherical inclusion cross-section, with an average error in dimension qualification of < 10%.\n
