    Inflatable structure is a promising technology with low weight, ease of packaging and reliability. Space inflatable antenna rod (SPINAR) has been developed as an ultra-light one-dimensional extendible structure driven by an inflatable actuator. SPINAR satisfies ever-intensifying requirements such as lightweight, high rigidity, high strength, high packaging efficiency, favorable antenna performance and simple extension mechanisms. For a scientific mission under consideration in ISAS/JAXA, the analysis of the requirements for structural design of one-dimensional extendible antenna structure and the detailed conceptual design were performed. Also, the spin extension test of SPINAR on a turntable under micro-gravity environment using airplane parabolic flight was conducted. In this paper, the analysis and evaluation of the structural feature and system performance are discussed based on the manufacturing the experimental model and the micro-gravity test.
