Abstract: Antenna module for a vehicle including a base suitable for being fixed to a vehicle body, a main board disposed horizontally on the base, a first, second, third and fourth radiant element that protrude in upper position from the main board. The first and the second radiant element have median axes that extend in the direction of the vertical axis and intersect the horizontal plane of the base in intersection points disposed on both sides with respect to the longitudinal axis of the base and spaced by distances from the longitudinal axis of the base. The third and fourth radiant elements have median axes that extend in the direction of the vertical axis and intersect the horizontal plane of the base in intersection points disposed on both sides with respect to the longitudinal axis of the base and spaced by distances from the longitudinal axis of the base.

Abstract: A manufacturing process of a rear window for vehicles including the following steps: provision of a glass plate with an external side suitable for being directed towards the exterior of the vehicle and an internal side suitable for being directed towards the interior of the vehicle; application of a heater on the internal side of the glass plate, the heater having two bus bars that are electrically connected to a positive pole and to a negative pole of a battery of the vehicle, respectively, and a plurality of horizontal heating lines that connect the bus bars; and application of antenna traces on the internal side of the glass plate, wherein the antenna traces have strips of transparent nanowires made of conductive material. The application of the antenna traces is made by spray-coating on the internal side of the glass plate.
