An antenna arrangement () comprising a radiation layer () comprising a first slot () and a second slot () extending along a first slot axis (D) and second slot axis (D), respectively, where the first and the second slots are arranged in a column () extending along a column axis (D), and where the slot axes are arranged at respective non-zero third and fourth angles (a, a) with respect to the column axis; and a distribution layer () facing the radiation layer (), comprising a first ridge waveguide comprising a first ridge () and a second ridge waveguide comprising a second ridge (), wherein waveguiding paths () of the first and second waveguides are configured to match respective shapes of the first and second ridges. A first section () of the first ridge () facing the first slot () extends along a first ridge axis (DI) and a second section () of the second ridge () facing the second slot () extends along a second ridge axis (D), where the ridge axes are arranged at respective non-zero first and second angles (a, a) with respect to the column axis, where the first and second angles (a, a) are configured to match the third and fourth angles (a, a), respectively.

Rotated ridge waveguide antenna

A micro strip to waveguide transition comprising a waveguide module and a section of printed circuit board (PCB). The waveguide module comprises a waveguide aperture and a repetitive structure, the waveguide aperture being arranged extending through the module for attaching a waveguide to an external side of the module, the repetitive structure comprising a plurality of protruding elements arranged to surround the waveguide aperture on an internal side of the module and to define a passage into the waveguide aperture on the internal side, wherein the repetitive structure is configured to attenuate electromagnetic signal propagation in a frequency band past the repetitive structure while allowing propagation via the passage, the transition further comprising a PCB with a patch antenna connected to a transmission line and arranged to face the passage into the waveguide aperture.
