Abstract
•The performances of different ultra-fast steerable phased array concepts are compared.•The performances are assessed with two parameters: the supported range and array gain.•The achievable steering range can be extended using interferometer based delays.
In this paper we compare different integratable ultra-fast tunable true-time delay concepts with respect to their performances in a phased array system. The performances of the schemes are assessed with respect to the supported range, i.e. the range within which beam steering for a given fractional bandwidth can be achieved with a gain flatness better than 3 dB. We also compare the array gain as of function of steering angle and fractional bandwidth.
