Abstract
An antenna device for automotive radar applications including an antenna assembly which comprises a front face in which at least one antenna aperture is arranged, configured to receive an incoming signal in form of primary rays impacting in the at least one antenna aperture. The front face of the antenna assembly further includes adjacent to the at least one antenna aperture scattering elements by which primary rays, impacting an area of the scattering elements, are at least partially reflected by the scattering elements and thereby separated into first secondary rays and second secondary rays, such that the first secondary rays and the second secondary rays cancel out each other at least partially by interference.
