Abstract: Space deployable antenna mechanism is one of the rapid developing research directions in recent years as well as the key equipment to support the large space antenna, and it has the development trend of higher aspect ratio, higher precision, higher stiffness and less mass. After nearly 30 years of development, amount of space deployable antennas have been applied to practical tasks. But the classic structural forms are not preferable to satisfy the increasing antenna performance requirement any more as the ultra-large antenna have become the mainstream demand. There are various deployable antenna mechanism forms with the level scale of a hundred of meters in recent years, such as collaborative deployable antennas, hoop-column antennas and membrane antennas, etc. It is mainly introduced that the typical structural forms, application cases and latest technical progress of the space deployable antenna mechanism, reviewing its research status of configuration design, optimization design and dynamic analysis, analyzing its current main problems and development trend, and providing references for researches on it.

Key words: deployable structure, space-borne antenna, configuration design, optimization design, dynamic analysis
