Abstract

A fiber grating prism (FGP) consisting of one single-mode fiber delay line and four tunable chirped grating delay lines is proposed and demonstrated. This FGP can provide five-channel time-delayed signals that can be fed to an antenna array to achieve continuous beam scanning. The proposed true-time-delay unit with 5-element phased array steerer is suitable for beamforming at frequencies up to 18 GHz.
