ABSTRACT:
A parabola antenna reflector incorporating an deploying apparatus of the invention has a disk shape having a predetermined radius of curvature. The reflector has a cross-shaped first reflector portion which extends to a peripheral portion of the reflector in the longitudinal direction, a pair of second reflector portions axially held at two sides of the first reflector portion to oppose each other and biased to open, and two pairs of third reflector portions axially held at two sides of each of the second reflector portions to oppose each other and biased to open. The pair of second reflector portions are held by a first locking mechanism in a folded state, and the two pairs of third reflector portions are held by second locking mechanisms in a folded state. The holding state of the second locking mechanisms is released when the folding state of the first locking mechanism is released and the second reflector portions begin to deploy.
