1. 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, wherein the substrate further comprises at least one electrical component on the first side, wherein each electrical component is enclosed by a corresponding one of plurality of chambers, and wherein the at least one electrical component comprises at least one of amplifiers, resistors, and capacitors;
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 such that the electromagnetic shielding structure extends from the antenna element module and having an electrically 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 of the substrate by at least one of adhesive, welding, soldering, electrically conductive gasket, and pressure methods.
