Abstract: A deployable reflectarray antenna stowable in a 6U CubeSat volume is deployed through tape deployers and quartz cables. The telescoping waveguide is attached to the horn with a threaded insert. The reflectarray antenna has, at 37.75 GHz, a directivity of 48.5 dBi, a gain of 47.8 dBi, and an aperture efficiency of 42%. Hinges with a ball-end screw enable precise control of deployment angle of adjacent panels in the reflectarray antenna.
