Abstract: An antenna reflector compatible with applications at high frequencies between 12 and 75 GHz and suitable for a paraboloidal or ellipsoidal geostationary space environment comprising a reflective face to focus electromagnetic radiation, comprises a superposition of at least one layer comprising a fiber composite material, the at least one layer of fiber composite material comprising angular sectors arranged around a center, each defined by a first central angle and oriented in a radial direction the median of the central angle, each of the angular sectors comprising the fiber composite material comprising first and second fibers oriented different first and second respective directions, the first direction forming a second angle with the radial direction of the angular sector. The angular sectors comprise three concentric areas: a central area, a peripheral area and an intermediate area situated between the central area and the peripheral area, the intermediate area forming a rim.

Abstract: A monolithic antenna source for space application comprises: a set of RF components conveying electromagnetic waves and dissipating thermal energy, and an RF radiating element having a circular or pyramidal radiating surface, the source further comprising thermal transfer means extending from the set of RF components to the RF radiating element and over at least a portion of the RF radiating element substantially along a longitudinal axis of the source, the RF radiating element being adapted to evacuate energy by thermal radiation.

Abstract: A antenna reflector compatible with high-frequency applications, i.e. applications using frequencies between 50 and 75 GHz, and suitable for use in a geostationary space environment, comprises a paraboloidal membrane comprising an active face allowing electromagnetic radiation to be reflected and a face opposite the active face. The opposite face of the reflector comprises ribs allowing the stiffness of the reflector to be increased, the ribs being placed on the opposite face in a way that forms a grid pattern between them.
