Abstract: The flexible tensioned thin-film deployable antenna is a kind of large-scale deployable antenna with wide application prospects,which integrates flexible electronics,flexible thin-film material,flexible structure and flexible deployable technology.The antenna has the characteristics of lightweight,high spreading ratio,high gain,and flexible beam,which can effectively meet the special needs of remote sensing,communication and deep space exploration satellites.The characteristics and current status of research on flexible tensioned thin-film deployable antennas were described;a survey of the antennas in terms of materials,structures and applications was carried out to provide an overview of the existing structural forms;the basic theory and comprehensive test methods of the development of the thin-film antennas were summarized;the key technical problems to be solved in the development of the large deployable space antennas were discussed in the context of specific engineering problems,and the technical development trend of the thin-film antennas was further analyzed.

Key words: flexible tensioned thin-film deployable antenna, thin-film structure, deployable structure, review, development trend
