Abstract
An integrated stiffener and RF reflector (stiffener/reflector) (100) for a RF emitter which includes: a plurality of vertical ribs (102) constituting side walls of the stiffener/reflector; a plurality of horizontal ribs (104) formed in a width direction of the stiffener/reflector; a top cover (204) including metallization layer (308), the top cover being electrically coupled to a ground layer (312) of the RF emitter and configured in such a way to direct all of RF energy in an opposite direction to the top cover. Each of the vertical (102) and horizontal (104) ribs has a sandwich structure, which includes: a foam core layer (302) disposed on a layer of the RF emitter (314); a thin film layer (306) bonded to sides and top of the rib to form facesheets of the sandwich structure.
