Abstract:
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.
