An array antenna

An array antenna extending along a first axis in a first direction in a first plane, and a second axis in a second direction in the first plane, the first direction being perpendicular to the second direction, the array antenna comprising:

• a substrate having a first side and an opposing second side;
• a plurality of connectors extending in a third direction from the first side, the third direction being perpendicular to the first plane;
• and
• an antenna element module having a radiating side and an opposing coupling side, wherein the antenna element module comprises a plurality of antenna elements arranged on the radiating side and an electromagnetic shielding structure arranged on the coupling side, the electromagnetic shielding structure having a connecting portion arranged to be mounted to the first side of the substrate;
• wherein the substrate is arranged to be coupled to the antenna element module such that the first side of the substrate faces the coupling side of the antenna element module and such that each connector is coupled to a corresponding antenna element of the plurality of antenna elements, and wherein the connecting portion of the electromagnetic shielding structure is joined to the first side.
