Full-metal X-band Reflectarray for Small Satellite Constellations

This paper presents a full-metal unit cell for reflectarray antenna. This unit cell has been designed to withstand the space environment, and can be scaled to operate from X-band to Ka-band with the same manufacturing process. In this paper, An X-band 3-panel reflectarray for small satellite has been designed as an example of application. The size of each panel is 200 x 350 mm². The reflectarray has been simulated on the [8-8.4] GHz band and shows a good stability on the band. The maximal gain is 28 dB and the half-power beamwidth is 8°.
