This paper proposes a high-gain Reflectarray Antenna (RA) design on an origami-inspired foldable structure, which is based on the straight-major square-twist pattern (SMST). The antenna was designed to operate at 16 GHz and direct its main beam along \varphi=0^{\mathrm{o}}, \theta=30^{\mathrm{o}} direction with a gain of 28.34 \mathrm{d}\mathrm{B}\mathrm{i}. The RA was excited by a horn antenna of 14 \mathrm{d}\mathrm{B}\mathrm{i} gain with Q-factor of 5.25 positioned at a distance of 10\lambda with a 10^{\mathrm{o}} offset angle. The foldable nature of our origami-inspired structure provides a 92% packing efficiency of the RA aperture surface area, thereby offering a significant advantage for small satellites and terrestrial tactical applications.
