Abstract

A reconfigurable reflectarray-cell has been designed to provide a large tunable phase range in the frequency band 117-130 GHz. The unit-cell comprises three parallel dipoles printed on a quartz-wafer and a tunable liquid crystal (LC) placed on a cavity between the dipoles and a ground plane. The simulation results show a tunable phase-shift in a range larger than 300 degree for a 10% bandwidth and low sensitivity to the angle of incidence.
