Abstract: A multi-faceted deployable antenna frame including a six-bar linkage structure in a lateral facet of the antenna frame, the six-bar linkage structure being convertible from a folded state into a deployed state and having two first bars and four second bars, each bar being coupled to two others by a hinge to form a closed loop, where in the deployed state, the six-bar linkage structure has a quadrilateral shape.

Abstract: A mechanical support ring structure for supporting a deployable space reflector antenna. The mechanical support ring structure is convertible from a folded state into a deployed state and includes a ring-shaped pantograph having a plurality of circumferentially arranged pantograph sections which are deployable for converting the mechanical support ring structure from the folded state into the deployed state, and a plurality of circumferentially arranged support rods, each pantograph section being arranged between a respective pair of support rods, wherein each pantograph section includes one or more pairs of pantograph rods which intersect crosswise with each other at a respective crossing position.

Abstract: Deployable support structures include a six-bar linkage structure as a lateral facet of a truncated pyramid. The six-bar linkage structure comprises six articulated struts, each coupled to two others by a revolute joint to form a closed loop. The six-bar linkage structure is convertible from a deployed state into a folded state and vice versa. In the deployed state of one embodiment, the six-bar linkage structure forms a trapezoid with two opposing first and second parallel sides formed by two struts arranged in series and coupled by a revolute joint at the center of the parallel sides. In the folded state, the two struts of each parallel side are pivoted around the joint so that opposing end portions of the struts are located side by side. Scalable and modular deployable structures can be made for space applications as well as civil constructions such as domes, roofs, housing, tents, and bridges.
