Abstract: A coincident phased dual-polarized antenna array configured to emit electromagnetic radiation includes: a plurality of electromagnetic radiators arranged in a grid, the plurality of electromagnetic radiators defining a plurality of notches; a ground plane spaced from the electromagnetic radiators; a conductive layer disposed between the electromagnetic radiators and the ground plane, the conductive layer having a plurality of slots laterally offset from the notches and being spaced apart from and electrically insulated from the electromagnetic radiators; and a plurality of feeds, each of the feeds spanning a corresponding slot of the slots and electrically connected to a portion of the conductive layer at one side of the corresponding slot.
