1. An antenna device comprising:
an antenna element configured to emit and receive electromagnetic waves;
a reflector configured to reflect the electromagnetic waves emitted from the antenna element; and
a substrate defining a main extension plane extending along a horizontal direction (Y) and a lateral direction (X), both of the reflector and the antenna element being positioned on the main extension plane of the substrate, a vertical direction (Z) extending perpendicular to the horizontal direction (Y) and the lateral direction (X), and thus perpendicular to the main extension plane of the substrate,
wherein the reflector is configured to spatially narrow in the vertical direction (Z), and spatially widen in the horizontal direction (Y), the electromagnetic waves emitted by the antenna element, and
wherein the reflector has a concave shape in the vertical direction (Z), thereby spatially narrowing, in the vertical direction (Z), the electromagnetic waves emitted by the antenna element upon reflection at the reflector, and the reflector has a convex shape in the horizontal direction (Y), thereby spatially widening, in the horizontal direction (Y), the electromagnetic waves emitted by the antenna element upon reflection at the reflector.
