摘要

We have proposed and designed a photonic true-time delay (TTD) steered phased-array antenna system that can work at high RF frequency with high angular resolution. Several elementary techniques have been studied and developed, including an optical realization of the Blass matrix based on our substrate-guided wave fanout structure, switching operation of wideband MSM and PIN photodetectors, and heterodyne RF signal generation. A design for the system demonstration that has the bandwidth from 18 to 26GHz is reported.
