| Title: | Silicon Photonics Optical Beamformer for Broadband Phased Array Antennas |
| Issue Date: | 2021-07-15 |
| Abstract: | 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. |
| Description: | Este projecto tem como objectivo o estudo, desenho e simulação de um beamformer óptico, a operar na banda Ka (26 - 40 GHz) implementado num circuito fotónico integrado. Este dispositivo deve ser capaz de gerar atrasos TTD (True Time Delay) de modo a evitar deformações de feixe, denominadas beamsquint, que afectam negativamente a qualidade do sinal transmitido. Esta funcionalidade tem como objectivo melhorar a performance de sistemas baseados em agrupamentos de antenas (Phased Array Antennas) para sinais com elevada largura de banda. Outro aspecto importante do projecto é a integração do circuito óptico num chip fotónico baseado na tecnologia de fotónica integrada em Silício, que permite o fabrico de dispositivos ópticos compactos e de baixo custo. |
