An origami-based engineering approach is applied to the folding design of tensioned precision space structures. Tension is a viable means of stiffening a flat antenna aperture, especially when stowed volume is paramount. Three folding patterns are described, and the design guidelines are developed. Deployment kinematics follow the simplicity of a single-degree-of-freedom mechanism for two of the three patterns. The panels are rigid, and articulations occur along the prescribed lines. These deployment architectures are compatible with storable tubular extendible member booms, articulated trusses, or continuous longeron coilable trusses, all commonly used to deploy spacecraft structures. High areal packaging densities were demonstrated: 1.0    m 2 / l for a diamond pattern with a high deployed aspect ratio and 0.5    m 2 / l for spiral and serpentine patterns compatible with high and low deployed aspect ratios. A double-layer material hinge method is also presented and used to enable the structures to fold, deploy, and be tensioned to a planar state.
