随着对高速和容量的要求的增加以及当前频率的拥塞，在身体区域无线通信中需要更高的频率。尤其是太赫兹频段因其潜在的容量和广泛的频率可用性而受到研究人员的极大关注。本文展示了无线体域网太赫兹传播的初步测量结果。天线集成谐振隧道二极管用作发射器，热释电探测器用作接收器。测量了2 cm到28 cm距离的接收电平，并导出了490 GHz的简单衰减模型。
As increased requirements for high speed and capacity and congestion of current frequencies, higher frequency is desired in body area wireless communications. Especially, terahertz band gains great attention for researchers for its potential capacity and wide frequency availability. In this paper, a preliminary measurement result of terahertz propagation for wireless body area network is exhibited. An antenna integrated resonance tunneling diode is used as a transmitter and a pyro detector are used as a receiver. Received level of the distance from 2 cm to 28 cm are measured and a simple attenuation model of 490 GHz is derived.
