Abstract
Described are several embodiments of parabolic reflective antenna systems where a flexible primary reflector is supported by radial ribs of shape memory material deployed by application of heat. Several feeds made with shape memory materials working with the reflector are presented. Feed preforms include corrugated, telescopic and flattened ribbon types which extend or unfurl into final shapes upon application of heat. Several antenna and feed embodiments also contain supports for secondary reflectors and patch antennas.
