Design of C-band Foldable Reflectarray Antennas by Flexible Textile with Copper Pattern Plating

This paper presents the design results of C-band foldable reflectarray antennas by flexible textile with copper pattern plating for small satellites. The reflectarray is composed of two textiles; one for ground and the other for patch. This configuration enables stowing compactly. The simulation of the reflectarray shows 30.9-dBi antenna gain with low sidelobe levels of less than 21.1 dB. The antenna is going to be fabricated and characterized.
