Title:
COMPACTLY STOWABLE, THIN CONTINUOUS SURFACE-BASED ANTENNA HAVING RADIAL AND PERIMETER STIFFNESS THAT DELPOY AND MAINTAIN ANTENNA SURFACE IN PRESCRIBED SURFACE GEOMETRY
Document Type and Number:
WIPO Patent Application WO2001080362
Kind Code:
A3
Abstract:
A space deployable antenna reflector surface is formed as a continuous laminate that is shaped to conform with a predetermined energy-focusing surface geometry. The laminate is formed of thin layers of flexible material, such as thin sheets of graphite epoxy, containing collapsible radial and perimeter stiffening regions. Due to its thinness, the reflector laminate is collapseible into a folder shape, that facilitates stowage in a restricted volume, usch as aboard the space shuttle. The stiffening elements of the mlaminate antenna structure facilitate depolying and maintaining the reflector in its intended geometric shape.
