Measurements of high-gain antennas at THz frequencies present challenges for traditional antenna measurement techniques. Aiming at the measurement problems of high-gain antennas at THz, the feasibility of various antenna measurement techniques including far-field, near-field and Compact Antenna Test Range(CATR), are discussed; features of each method and the limitations of these methods applied to THz bands are presented. And the result indicates that the CATR based on hologram has a broad application prospect in high-gain antenna measurement at THz band.
