摘要：
With the requirements for improvement of earth observation range and accuracy, large-scale two-dimensional deployable antennas are urgently needed. In this paper, a deployable structure for a planar antenna with one degree of freedom and a flat reflection surface that can realize two-dimensional deployment with a compatible back frame is proposed based on a double-layer Miura-ori pattern. First, an antenna folding scheme with rectangular facets is proposed with the Miura-ori pattern. Through the method for hinge removal and replacement, a deployable antenna mechanism with a flat reflection surface is accomplished. Then, a kinematic model of the deployable structure is established to analyze its kinematic characteristics and prove the equivalence of motion before and after changing the hinges. By converting the rotating pairs between the two layers of origami into cylindrical pairs, a thick-panel form of double-layer origami is constructed. On this basis, a compatible back frame for the planar antenna mechanism is designed and a corresponding prototype is fabricated. The work paves the way to design deployable structures.
