Abstract: Deployable reflector antenna includes a fabrication hub in which at least one additive fabrication unit disposed. The additive fabrication unit is configured to form at least one rigid structural element of a reflector antenna system. In a stowed condition, an RF reflector material comprised of a flexible webbing is disposed in a stowed configuration proximate to the fabrication hub. A fabrication control system controls the additive fabrication unit so as to form the at least one rigid structural element. The RF reflector material is arranged to transition during the additive fabrication process from the stowed configuration in which the flexible webbing material is furled compactly at the fabrication hub, to a deployed configuration in which the flexible webbing material is unfurled.

Abstract: Folded optics reflector system includes a hoop assembly configured to expand between a collapsed configuration and an expanded configuration to define a circumferential hoop. A mesh reflector surface is secured to the hoop assembly such that when the hoop assembly is in the expanded configuration, the reflector surface is expanded to a shape that is configured to concentrate RF energy in a desired pattern. The system also includes a mast assembly comprised of an extendible boom. The hoop assembly is secured by a plurality of cords relative to a top and bottom portion of the boom, whereby upon extension of the boom to a deployed condition, the hoop assembly is supported by the boom. A subreflector is disposed at the top portion of the boom.

Abstract: An antenna structure, such as an antenna reflector, comprises a collapsible mesh and catenary tie/cord attachment structure, retained in tension by a plurality of variable geometry spreader-standoffs connected to an inflatable tubular support hoop. The standoffs decouple the energy-focusing geometry of the antenna surface from the hoop, so as to reduce the sensitivity of the shape of the surface to variations in the shape of the tubing. Each spreader-standoff is connected to the hoop at a hinge joint of a pair of spreader-standoff elements, by a radial connection element retained in tension by the adjoining tubing. The hinge joint of a respective spreader-standoff pair is adjacent to an inner diameter side of the hoop, while distal locations of the spreader-standoff elements are located beyond an outer diameter side of the inflated hoop.
