摘要：

Measurements of high-gain antennas at THz frequencies present challenges for traditional antenna measurement techniques. Far-field measurements are not feasible because of the large far-field distance requirement and therefore inevitable signal attenuation and distortions. Adequate accuracy in the collimating element manufacturing is the major issue in the compact antenna test ranges, and the realisation of the accurate planar movement of the probe antenna is the main challenge in the planar near-field measurements. Brief review of the most feasible measurement techniques for high-gain antenna testing at THz frequencies is presented, and relevant work at MilliLab is described.
