摘　　要：太赫兹波作为一种新的高频段资源,有着更高的载波频率,可以承受更大的带宽和传输速率,成为新一代宽带通信中的研究热点。本文基于纯电子学器件成功搭建300 GHz的太赫兹无线通信系统,其发射机结构简单,复杂度相比光子辅助系统更低。进行了无线距离50 m和100 m的信号传输实验,对系统的传输性能进行了实验探究,验证了传输性能和传输速率、发送电压之间的关系。目前,在不使用功率放大器(PA)的情况下,100 m是全电子太赫兹无线传输系统能达到的最远距离。As a new type of high-frequency band resource,terahertz wave has a higher carrier frequency,it can withstand larger bandwidth and transmission rate,therefore,it has become a research hotspot for new generation broadband communications.A 300 GHz terahertz wireless communication system is constructed based on pure electronic devices,in which the transmitter has a simple structure and the whole system is less complex than the photon-assisted system.Signal transmission experiments with wireless distances of 50 m and 100 m are conducted.The transmission performance of the system is explored and the relationships among the transmission performance,transmission rate and transmitting voltage are studied.As far as we know,100 m is the longest distance that an all-electronic terahertz wireless transmission system can achieve without using a Power Amplifier(PA).
