Abstract
A method for beam steering and beam forming an antenna is disclosed herein that includes illuminating an optical fiber with a light source, thereby transmitting a signal through the optical fiber to an electro-optical switch. The electro-optical switch is actuated with the signal from the light source, thereby switching an electrical load in the electro-optical switch. At least one antenna element in an array of antenna elements is excited with RF radiation radiated by a driven element via an RF transmission line and reradiated from parasitic elements, thereby beam steering and beam forming the antenna.
