Abstract :
This letter presents a new phase-shifting cell for linearly polarized reflectarray applications. It provides a nearly 360° phase range and naturally comes back to its initial geometry after the phase cycle has been achieved. A complete analysis of the resonating mechanism is given, and a low dispersion (<;30°/GHz) is demonstrated over a large bandwidth (18%) in simulation.
