摘要

采用一种基于液晶材料的曲线移相器对一种ka波段天线阵列的波束进行电子引导。通过对LC曲线移相器施加偏置电压，可以调节天线元件的相位，使主波束向期望的方向移动。以$\mathbf{1}\乘以\mathbf{4}$阵列天线为例，采用基于LC的曲线移相器，主波束可以控制在$\pm \mathbf{17}^{\mathbf{o}}$的范围内。

Liquid Crystal Material based Electronically Beam Steering Antenna at Ka-band for 5G Applications

A meander line phase shifter based on liquid crystal (LC) material is used to electronically steer beam of an antenna arraydesigned for ka-band. Based on biasing voltage applied on LC based meander line phase shifter, phases can be adjusted for antenna elements to steer the main beam in the desired directions. For theexample of a $\mathbf{1}\times \mathbf{4}$ array antenna with LC based meander line phase shifters, the main beam can be steered in the range of $\pm \mathbf{17}^{\mathbf{o}}$.
