A photonic-assisted reactive near-field scanner for planar antennas is presented. We, KRISS (Korea Research Institute of Standards and Science), have recently developed electro-optic sensors as all-dielectric electric field probes and utilized them for field imaging of antenna patterns. The performance of our system, as well as calibration of the system drift, are introduced by exploring 4 × 4 patch antenna arrays at the K-band.
