Abstract
An expandable structure is formed by assembling together a plurality of structure modules each comprising a polygonal prism-shaped frame. Each pair of adjacent structure modules are connected together using frame members in common to form a hoop-shaped frame structure as a whole. Thus, it is possible to form a large-sized expandable structure, for example, an expandable antenna having an enlarged aperture. Since frame members of each pair of adjacent structure modules are used in common, it is possible to obtain a compact expandable structure.
