摘要

本文利用液晶的连续可调谐特性和非辐射介质波导优异的电学性能，设计了一种工作在f波段(90-140 GHz)的太赫兹移相器。仿真结果表明，液晶移相器由偏置电极网络控制，最大移相度可达500度。移相器具有良好的匹配性能，在60 GHz带宽范围内回波损耗几乎小于- 10 dB。

Design of a terahertz phase shifter based on liquid crystal

In this paper, a terahertz phase shifter work in F-band (90–140 GHz) is designed based on the continuous tunability of liquid crystal and the excellent electrical properties of non radiative dielectric (NRD) waveguide. The simulation results show that the liquid crystal phase shifter is electrically controlled by the bias electrode network, and the maximum phase shift is 500 degrees. The phase shifter shows excellentl matching, and the return loss is almost less than −10 dB in the bandwidth up to 60 GHz.
