A new measurement method for characterization of liquid crystal reflectarrays (LC) is presented. The phase and amplitude characteristics are determined by near-field measurements close to the antenna surface, using high resolution probes, which have been developed to resolve individual patches on the reflectarray. Measurement results showed a phase angle range of 280° of individual detected LC patches. The measurement setup and corresponding measurement results at 35GHz are presented. The procedure used for measurement automation is also explained.
