A millimeter-wave antenna system includes: a ground plane; and a folded dipole radiator including: a plurality of feeds each extending away from the ground plane from a proximal feed end to a distal end; a plurality of radiating arms each coupled to and extending away from the distal feed end of a respective one of the plurality of feeds; and a plurality of folded conductors each coupled to a respective one of the plurality of radiating arms and each having a distal portion extending toward the ground plane to a distal conductor end; where each of the plurality of feeds and each of the plurality of radiating arms comprises an electrical conductor; and where the folded dipole radiator is discontinuous, without a conductive connection between the plurality of feeds via the plurality of radiating arms.
