Antenna device

Abstract

An antenna device includes a printed circuit board and an associated electronic component as well as an antenna assembly including at least two individual antenna elements interconnected to the electronic component configured to transmit and/or receive a signal. The antenna elements each include at least one waveguide channel (9) interconnecting in the antenna assembly: (i.) a first waveguide aperture arranged at a back face of the antenna assembly, the first waveguide aperture interconnected to the electronic component and configured to transmit and/or receive signal, and (ii.) a second waveguide aperture (11) arranged at a front face of the antenna assembly configured to transmit and/or receive signal. The second waveguide aperture (11) is horn shaped and a flare section (36) is arranged adjacent to the horn shaped second waveguide aperture (11).
