Microwave antenna including an antenna array including a plurality of antenna elements
First Claim
1. A microwave antenna comprising an antenna array comprising a plurality of antenna elements, an antenna element comprising:
- 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 being electrically contacted to said ground plane and said line structures; and
terminals being electrically contacted to said integrated circuit.
