Abstract
A scrollable reflectarray antenna system and methods for reconfiguring electromagnetic (EM) characteristics of the reflectarray antenna are provided. The reconfigurable reflectarray antenna includes a flexible substrate; a plurality of reflectarray patterns disposed on a surface of the flexible substrate, each reflectarray pattern comprising a plurality of reflectarray elements; and an actuator system coupled with the flexible substrate. The actuator system is configured to scroll the flexible substrate to different operational positions such that when layout of the plurality of reflectarray patterns is changed, at least one EM characteristic of the reflectarray antenna is reconfigured. In a predetermined operational position, an aperture of the reflectarray is formed by two reflectarray patterns that are optimized to direct an illuminating beam in a new direction.
