Patent ID: 12009581

Abstract:
An antenna device (100) includes an antenna element (102) for emitting and receiving electromagnetic waves, a reflector (104) for reflecting the electromagnetic waves emitted from the antenna element (102), and a substrate (106) on which the antenna element (102) and the reflector (104) are positioned. The substrate (106) defines a main extension plane (108) extending along a horizontal direction (Y) and a lateral direction (X), wherein a vertical direction (Z) extends perpendicular to the horizontal direction (Y) and the lateral direction (X), and thus perpendicular to the main extension plane (108). The reflector (104) has a concave shape (112) in the vertical direction (Z) thereby spatially narrowing in the vertical direction (Z) the electromagnetic waves emitted by the antenna element (102), and has a convex shape (110) in the horizontal direction (Y) thereby spatially widening in the horizontal direction (Y) the electromagnetic waves emitted by the antenna element (102).
