Abstract: An antenna device for automotive radar applications includes a printed circuit board having a front face and a back face and an electronic component which is interconnected to the printed circuit board and an antenna layer having a front face and a back face, which back face is interconnected to the front face of the printed circuit board. At least one waveguide aperture is interconnected to the front face of the antenna layer and is communicatively connected to the electronic component by at least one waveguide channel, wherein the at least one waveguide channel comprises a conductive surface for guiding an electromagnetic field between the electronic component and is formed by a recess arranged between the back face of the antenna layer and the front face of the printed circuit board.

Abstract: A waveguide antenna with an antenna proximal side and an antenna distal side. A number of waveguide openings for transmitting electromagnetic signals to and/or receiving electromagnetic signals from an environmental space is arranged at the antenna distal side. An antenna interface structure connects the waveguide antenna to a printed circuit board and/or a semiconductor component and includes a number of interface waveguide apertures arranged in an interface carrying surface. The interface carrying surface extends transverse to a normal axis. Each interface waveguide aperture is coupled with at least one associated waveguide opening such that the respective interface waveguide aperture and the associated at least one waveguide opening are offset with respect to each other transverse to the normal axis.

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.
