1. A laminated glazing assembly comprising:
an outer glass substrate having an outer surface (P1) and an opposing inner surface (P2);
an inner glass substrate having an inner surface (P3) and an opposing outer surface (P4);
an opaque band disposed on one of the P2 surface and the P4 surface and extending at least partially around a peripheral edge of the laminated glazing assembly;
a polymeric interlayer disposed between the P2 surface of the outer glass substrate and the P3 surface of the inner glass substrate;
an antenna assembly disposed between the polymeric interlayer and one of the P2 surface and the P3 surface and assembly comprising:
a film layer including a first surface facing one of the P2 surface and the P3 surface and an opposing second surface facing the polymeric interlayer;
a plurality of conductive wires disposed on one of the first surface and the second surface of the film layer and arranged to form a mesh having an aperture ratio of 90% or greater; and
a coupling portion electrically coupled to the mesh and disposed on the same surface of the film layer as the conductive wires and arranged at the peripheral edge of the laminated glazing assembly; and
a feeding element coupled to the P4 surface and aligned with the coupling portion such that the opaque band obscures the feeding element as the laminated glazing assembly is viewed from the P1 surface, the feeding element capacitively coupled to the coupling portion of the antenna assembly to energize the antenna assembly to transmit and/or receive 5G radio frequency signals.
