1. A millimeter-wave antenna for 5G applications, comprising a multilayer structure comprising:
an upper outer layer comprising at least a plurality of first radiating elements arranged spaced apart from each other on a first dielectric sublayer;
a first inner layer arranged below the upper outer layer and comprising a plurality of through slots suitable for conveying, towards said plurality of first radiating elements, feeding signals to be radiated;
a second inner layer arranged below and adjacent to said first inner layer, said second inner layer comprising at least one dielectric sublayer on which there is arranged a plurality of conductive lines suitable for conducting the feeding signals to be radiated towards the plurality of first radiating elements;
a further inner layer arranged below and adjacent to said second inner layer and comprising a plurality of first through openings, each of said first through openings being formed on the further inner layer in a position corresponding to the position of at least one associated through slot of said plurality of through slots; and
a first additional layer arranged below and adjacent to said further inner layer, said first additional layer comprising a plurality of second through openings substantially aligned each to a corresponding first through opening with respect to a substantially vertical reference direction wherein at least said first inner layer comprises a plurality of metallized through holes.
