Abstract
This paper presents the design of a flexible using two set of flexible material classes: polymer and textiles. ShieldIt Super conductive fabric and felt are used as the textile material, and its performance is compared with another version designed on a polydimethylsiloxane (PDMS) polymeric substrate. They are both built using a 4 × 4 dodecagonal unit element array backed by a rectangular patch, each sized at 54 × 64 × 3.34 mm

). Both of them are validated to be operational centered at 2.2 GHz with a measured conversion efficiency of more than 90% from 1.578 to 2.578 GHz (48.12%) for the textile prototype. The results of the bending investigations suggest that the deployment mechanism must ensure a flat polarizer condition to enable its optimal performance.
