One meter deployable reflectarray antenna for earth science radars

This paper describes the development of a 1-m deployable reflectarray antenna which is designed to fit in a 6U (10×20×30cm3) class CubeSats. It operates at 35.75 GHz for the measurement of atmospheric processes over a short, evolutionary timescale. It deploys into a 98.6 cm × 82.1cm flat reflector. This antenna provides a gain of 48.0 dBi and an aperture efficiency of 44%. It consists of a cassegrain reflectarray using 14 deployable panels, one fixed panel and a telescoping feed and subreflector.
