Reconfigurable Array of Radiating Elements Controlled by Light

A totally new class of reconfigurable, adaptive antennas based on the ability of a semiconductor to drastically change its properties on exposure to light in its absorption band is proposed. The innovative concept for the reconfigurable array of radiating elements (RARE) utilizes principles of microstrip flat-surface antennas with the additional advantages of wide-range tunability (several decades) and agile beam scanning. This performance is achieved by changing the antenna pattern according to the desired output. This pattern change can be accomplished with a spatial light modulator (SLM) or an individually addressable diode laser array. Phase I of this program is focused on a feasibility demonstration of a reconfigurable array of 4 x 4 radiating elements using a single feed. In Phase II, the design and fabrication of a deliverable prototype of the reconfigurable array of radiating elements controlled by light will take place. The system integration of the RARE, its testing, ultimate product development and commercialization will be done in close collaboration and partnership with California Microwave, Inc., Woodland Hills, CA.
