Abstract
A reconfigurable antenna system is provided. The reconfigurable antenna system includes a substrate and a vanadium dioxide film deposited on a surface of the substrate. The vanadium dioxide film is configured to transition from a first phase to a second phase in response to a stimulant, such as coherent laser light. The reconfigurable antenna system also includes a transition source such as an optical engine configured to stimulate the vanadium dioxide film from the first phase to the second phase. The reconfigurable antenna system also includes a microcontroller in communication with the transition source. The microcontroller is configured to change a configuration of the reconfigurable antenna system by providing the transition source to the film according to a predetermined antenna image, the configuration of the reconfigurable antenna system including at least one of the radiation polarization, an operating frequency, and radiation pattern of the reconfigurable antenna system.
