1. Antenna device that is configured to perform wide angle two-dimensional scanning, and which is suitable for wireless communication protocols, wherein the antenna device comprises:
i) a primary plate containing a multitude of adjacent antenna units, wherein each antenna unit is provided with a respective electrically conductive antenna patch which is provided at a top side of the primary plate, and
ii) a dielectric resonator section which is arranged above the primary plate, which dielectric resonator section comprises a multitude of adjacent resonator units which are either directly or indirectly attached to the top side of the primary plate, in such a way that an individual resonator unit is arranged above each individual antenna unit,
wherein the resonator units are made of dielectric material, and each resonator unit comprises a stud that protrudes in an upward direction from the primary plate, and the studs of the resonator units are dimensioned such that the studs are laterally spaced apart from each other,
characterized in that the antenna device additionally contains:
iii) a grate layer comprised of a planar metallic sheet perforated by a multitude of adjacent grate holes, wherein the grate layer is attached directly or indirectly to the top side of the primary plate and in a parallel orientation thereto, and the grate layer is configured such that a grate hole is positioned above each antenna unit, and each grate hole is dimensioned such that the stud of the resonator unit that is arranged above each antenna unit, fits within the respective grate hole.
