1. A laminated glazing panel comprising:
an outer pane of glass having an outer face and an opposite inner face,
an inner pane of glass, having an outer face and an opposite inner face, the inner pane of glass being laminated to the outer pane of glass by a thermoplastic interlayer,
an antenna structure comprising:
a. a feeding structure comprising at least one ground conductor and a signal conductor, the at least one ground conductor being electrically isolated from the signal conductor by a gap,
b. a radiator, fed by the feeding structure and electrically connected to the signal conductor, and
a connector, to power the antenna structure, through the feeding structure, comprising at least one additional conductor connected to the signal conductor, and at least one further conductor connected to the at least one ground conductor, at their extremities,
wherein at least the radiator of the antenna structure, and the signal conductor of the feeding structure and the extremity of the additional conductor are provided on at least one of the surfaces of the inner faces of the outer and/or the inner panes of glass of the laminated glazing panel,
wherein the radiator and the feeding structure conductors are deposited directly on the glass, and
wherein the signal conductor lies on a same glass face as the radiator, while the ground conductor is implemented on any glass face of the laminated assembly provided that the ground conductor does not lie on the same glass face as the radiator.
