Abstract
A deployable antenna which has a larger aperture diameter by four-side links provided in at least three stages and which includes: six deployment link mechanisms () arranged radially from a central shaft so as to support an outer edge portion of a flexible reflector mirror surface; and one deployment driving mechanism () arranged at a lower portion of a center of arrangement of the six deployment link mechanisms, for unfolding the six deployment link mechanisms. Each of the six deployment link mechanisms includes a first four-side link (), a second four-side link (), and a third four-side link () arranged in an order from a position of the central shaft, around which the six deployment link mechanisms are arranged, toward an outer side of the each of the six deployment link mechanisms so that the each of the six deployment link mechanisms is structured to be foldable in three stages.
