ABSTRACT:
An improved furlable antenna particularly suited for use in a celestial space environment. The antenna is characterized by an actuator comprising an elastomeric member of an annular configuration, an annular array of uniformly spaced antenna ribs rigidly affixed at the base ends thereof to said actuator and supported thereby for pivotal displacement from a deployed configuration, wherein the ribs are substantially radially extended from said actuator to a furled configuration wherein the ribs are extended in substantial parallelism with the axis of the actuator, a flexible reflecting web affixed to the ribs, and a plurality of angularly spaced bearing blocks supporting every radially extended section of the member for rotation about its own centroid.
