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...
In this paper, we introduce a simple and wideband characterization method for electric field probes using a transfer standard. As a transfer standard, a thin disk-type reference probe that can operate from 50 to 1000 MHz is used and calibrated using a micro transverse electromagnetic (mu-TEM) cell. A gigahertz transverse electromagnetic (GTEM) cell is used to generate a reference electric field. It...
