A description is given of two antenna standards that were assessed to be capable of assuring the required service quality and availability. Both antennas have an offset configuration with three reflectors. The main reflector is a paraboloid which is realized with carbon-fiber multilayered materials. The two shaped metallic subreflectors and a specially designed feed system incorporating a frequency selective surface allow a compact antenna structure design that provides high gain, low sidelobes, and good cross-polarization performance
