An example non-inductive, resonant near-field antenna includes: (i) a conductive plate having first and second opposing planar surfaces and one or more cutouts extending through the conductive plate from the first surface to the second surface; (ii) an insulator; and (iii) a feed element, separated from the first surface of the conductive plate by the insulator, configured to direct a plurality of RF power transmission signals towards the conductive plate. At least some of the plurality of RF power transmission signals radiate through the cutout(s) and accumulate within a near-field distance of the conductive plate to create at least two distinct zones of accumulated RF energy at each of the cutout(s). Furthermore, the at least two distinct zones of accumulated RF energy at the cutout(s) are defined based, at least in part, on a set of dimensions defining each of the cutout(s) and an arrangement of the cutout(s).
