摘要
对于高增益天线,当频率达到太赫兹频段时,传统的天线测量技术均面临巨大挑战。针对太赫兹高增益天线的测量问题,论述了各种天线测量技术,如远场法、近场法和紧缩场法的可行性,分析了其各自的特点及其应用在太赫兹频段的局限性,基于全息的紧缩场测量技术在太赫兹高增益天线测量中,具有广阔的应用前景。
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.
