Microwave antenna including an antenna array including a plurality of antenna elements

Abstract

A microwave antenna comprises an antenna array comprising a plurality of antenna elements. An antenna element comprises a cover, a hollow waveguide formed within the cover for guiding microwave radiation at an operating frequency between a first open end portion and a second end portion arranged opposite the first end portion, a septum arranged centrally and along the longitudinal direction within the waveguide and separating said waveguide into two waveguide portions, a substrate arrangement arranged at the second end portion within the cover, said substrate arrangement comprising a ground plane and line structures arranged on both sides of and at a distance from said ground plane and a substrate integrated waveguide, a waveguide transition arranged between said hollow waveguide and said substrate integrated waveguide, an integrated circuit arranged within said cover and electrically contacted to said ground plane and said line structures, and terminals electrically contacted to said integrated circuit.
