PROBLEM TO BE SOLVED: To provide a light artificial satellite antenna which does not have bad influence on a satellite orbit at the time of extension, and solve a problem of hardening after extension. SOLUTION: The artificial satellite antenna comprises a shell structure 1 of an STEM type, and inflatable structure 2 functioning as an actuator for extension of the shell structure 1. A tube 6 of the inflatable structure 2 is arranged so as to be inserted in a hollow cylindrical part of the shell structure 1. The tube 6 is expanded by the pressure of gas supplied into the tube 6, and the shell structure 1 is extended by using the expanding force of the tube 6 as driving force. The artificial satellite antenna having merits of both antennas of the STEM type and the inflatable structure, and avoiding demerits of both antennas can be provided. COPYRIGHT: (C)2006,JPO&NCIPI
