TL;DR: In this paper, the design and performance of the circularly polarized X-band deployable reflectarray developed for the Mars Cube One (MarCO) mission is described and evaluated.
Abstract: Mars Cube One (MarCO) is the first CubeSat mission developed for operation at Mars. MarCO will provide a bent pipe telecom relay to Earth for NASA's InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) mission during its Entry, Descent, and Landing (EDL) sequence. The MarCO High Gain Antenna (HGA) is a key enabling technology for this mission and presents a tremendous technical challenge due to the limited mass and volume of a 6U CubeSat. This paper presents the design and performance of the circularly polarized X-Band deployable reflectarray developed for MarCO.

07 Jul 2016TL;DR: In this paper, a reflectarray antenna comprises panels connected by rotating hinges, which are stowed folded around a satellite body and deploy by actuating the spring loaded hinges to extend and form a reflect array for operation in the K/Ka or X-band.
Abstract: A reflectarray antenna comprises panels connected by rotating hinges. The panels are stowed folded around a satellite body and deploy by actuating the spring loaded hinges to extend and form a reflectarray for operation in the K/Ka or X-band. The feed deploys from the satellite body to allow formation of a high gain reflectarray antenna that occupies limited space in small satellite operations.
