Slot array antenna (10) with waveguide feed comprising at least one radiating waveguide (20) comprising a radiating slot array (21) and at least one coupling slot (31) adapted for feeding the at least one radiating waveguide (20) with a radiofrequency electromagnetic radiation, the antenna (10) having a multi-layer structure and comprising:
- a first plate-shaped substrate (11) made from dielectric material comprising a first metalized layer (1) and a second metalized layer (2) respectively arranged on a first face and an opposite second face of the first plate-shaped substrate (11), the first (1) and the second (2) metalized layer respectively representing a first confinement wall and a second opposite confinement wall of said radiating waveguide (20), the radiating slots (21) being openings made in the first metalized layer (1) and the at least one coupling slot (31) being an opening made in the second metalized layer (2);
- a second plate-shaped substrate (11) made from dielectric material having a third face coupled with the second metalized layer, the antenna also comprising at least one feeding waveguide (40-43) of said radiating guide (20) operatively coupled with the latter through said coupling slot (31), the feeding waveguide (40-43) being made in the thickness of the second plate-shaped substrate (2). In the aforementioned antenna the second metalized layer (2) represents an upper confinement wall of the at least one feeding waveguide, which is a shared confinement wall between said radiating waveguide and said feeding waveguide. |
