Fabricated prototypes of the reference, i.e. without (WO) metasurface slots, and the proposed, i.e. with (W) metasurface slots, on-chip antennas. (a) Top-view of the reference on-chip antenna, (b) top-view of the proposed on-chip antenna, (c) back-view of both op-chip antennas, and (d) the simulated and measured reflection-coefficient response.
