Abstract
An aperture-coupled phase-shifter element providing a very wide range of phase delay is proposed as a unit cell in reflectarrays. A range of phase delay larger than 1600° has been achieved by using a U-shaped true-time delay line. Theoretical results are validated by comparing them with the measurements of two elements in a waveguide simulator, showing good agreement for both phase delay and losses.
