摘要

本文介绍了在人体附近测量300 ghz波段无线电传播的到达方向(DOA)的方法。我们开发了一种高速太赫兹半球扫描仪，可以以0.5°的角分辨率测量300 GHz频段无线电信号的DOA，以及300 GHz频段复杂介电常数接近人体的人体幻影。此外，DOA测量结果表明，在300 GHz时，服装对人体附近的衍射和反射特性有显著影响。

Measurement of 300 GHz Band Radio Propagation Characteristics in the Vicinity of Human Body using Terahertz Hemispheric Scanner

This paper presents the measurement of the direction of arrival (DOA) of 300-GHz-band radio propagation in the vicinity of a human body. We have developed a high-speed terahertz hemispheric scanner that can measure the DOA of 300-GHz-band radio signals with an angular resolution of 0.5°, and a human body phantom whose complex permittivity is close to the human body at 300 GHz band. Furthermore, DOA measurement results indicate that clothing significantly affects diffraction and reflection characteristics near a human body at 300 GHz.
