1. Antenna device for near-field illumination of the skin by millimeter waves, wherein said device is configured to superimpose a plurality of electromagnetic modes in the near field using a multilayer structure comprising, according to a vertical direction of stacking:
a first power supply layer comprising at least a first dielectric on an application-specific integrated circuit and on a first lower part of a metallic DC power supply circuit,
a second DC power supply layer, superimposed on the first power supply layer in the vertical stacking direction, and comprising a second upper part of a metallic DC power supply circuit,
a third layer, superimposed on the second supply layer in the vertical stacking direction, and comprising a second dielectric on a metal plane,
a fourth layer comprising at least one planar radiating element of said antenna device, the fourth layer is superimposed on the third layer in the vertical stacking direction, the metal plane of the third layer acts as a ground plane of the radiating element, and
a fifth layer, superimposed on the fourth layer in the vertical stacking direction, and comprising a radome capable of separating said at least one radiating element from the skin,
the antenna device further comprising at least one feed line extending vertically from the first layer to the fourth layer.
