Scalable, Deployable, Flexible Phased Array Sheets

Large aperture flexible and deployable phased arrays will enable emerging spacecraft, body-conforming arrays, and terrestrial deployable microwave systems. The flexible phased array design paradigm is enabled by small, multi-function radio frequency integrated circuits and low mass radiators, which avoid conventional dielectric materials. This paper presents a 256 element, 30 cm x 30 cm flexible phased array operating at 10 GHz. A novel beam-focusing algorithm is used to demonstrate 2-d beam-steering and deformation correction capabilities of the flexible phased array.
