A high-frequency, e.g., microwave, antenna is stamped from a single sheet of electromagnetically conductive material, e.g., a metal plate. A manufacture comprising a frame, a plurality of radiator antenna elements, a plurality of first supports each connecting a radiator antenna element to the frame, a feed network connected to the radiator antenna elements, and a plurality of second supports connecting the radiators and the feed network to each other and to the frame, are stamped out of the single sheet. A combiner may be included in the manufacture as well. The second supports provide alignment and rigidity during manufacture and assembly. Preferably, a plurality of the manufactures are stamped out side-by-side from a single roll for ease of automated manufacture and assembly. The frame is either made in two pieces or is bent relative to the resonator antenna elements along fold lines, to provide an offset of the radiators from a ground plane. The frame is mounted on the ground plane, and the second supports are then removed. Preferably, the feed network is positioned (e.g., by being bent) to lie closer to the ground plane than the radiator antenna elements.
