Resumo: This project proposes the design of a Photonic Integrated Circuit, or PIC, Optical Beaformer for broadband Phased Array Antennas, or PAA, operating in the Ka band (26 - 40 GHz). The beamformer circuit should implement a True Time Delay device that enables seamless phase tuning for each radiating element that is independent from frequency. The frequency independence of the generated delays avoids a recurring phenomenon on PAA systems known as beamsquint, which consists in deformation of the array radiation pattern that deteriorates the quality of the transmitted signal. Therefore, by eliminating beamsquint, this technology should allow PAA based systems to be used in broadband communications, which are becoming evermore pervasive, due to modern day demands for high-speed data tranfer. This project also aims to take advantage of recent integrated phtonics techonology, in order to fabricate compact and cheaper optical circuit devices.
