Abstract
A waveguide antenna with an antenna proximal side and an antenna distal side. A number of waveguide openings for transmitting and/or receiving electromagnetic signals to and/or from an environmental space is arranged at the antenna distal side. The waveguide antenna includes an antenna interface structure that includes interface waveguide apertures arranged in an interface carrying surface that 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 waveguide opening(s) are offset with respect to each other transverse to the normal axis. Each interface waveguide aperture and at least one coupled waveguide opening are configured for transmitting and/or receiving electromagnetic signals with respective polarizations rotated against each other. At least two neighboring interface waveguide apertures may be interlaced with each other, and/or the interface waveguide apertures may in each case enable a simultaneous and/or alternative transferring of at least two electromagnetic signals of different polarization, and/or the interface waveguide ap…
