We have previously proposed a concept for an antenna that can self-deploy in zero gravity using centrifugal force. Before deployment, the antenna has the shape of a polygonal column with a diameter of 0.5 meters and a height of 1 meter. When it deploys completely, it becomes a polygonal disk with a diameter of 2 meters and a thickness of 30 millimeters. We have performed alternative deployment tests in zero gravity in water by forces closely simulating centrifugal force. The tests verify that the antenna can deploy completely. However, the tests cannot simulate zero gravity and the centrifugal force completely. In this paper, the reliability of the deployment in zero gravity using centrifugal force is verified by structural analysis.

In this paper, a self deployable large disk antenna is proposed for power transmission between locations in space. Its mechanism of self deployment is examined through a geometrical study. This antenna is discussed for use in a power transmitting test using an S-520 sounding rocket in a few years time.
