摘要

报道了一种覆盖20 GHz ～ 23 GHz的流态可重构透镜天线。该天线是一种改进的对足维瓦尔第天线单元，具有流体加载的介质透镜，以促进单单元波束导向三种离散波束导向状态。在这项工作中使用的液体是乙酸乙酯(C4H8O2)， $\epsilon_{r}=6.0+j0.059,\ \tan\delta=0.35$在2.4 GHz。天线元件和透镜使用含有$\epsilon_{r}=3.55$和$\tan\delta=0.0027$的基板制造。实验结果表明，该天线可实现30°的波束导航。

20 GHz-23 GHz Antenna with Tri-State Output Beam-Steering using Fluidic Lens

A fluidically reconfigurable lensed antenna is reported that covers 20 GHz to 23 GHz. The antenna is a modified antipodal Vivaldi antenna element with a fluidically-loaded dielectric lens to facilitate single-element beam-steering for three discrete beam-steering states. The fluid used in this work is ethyl acetate (C4H8O2) with $\epsilon_{r}=6.0+j0.059,\ \tan\delta=0.35$ at 2.4 GHz. The antenna element and lens are fabricated using a substrate with $\epsilon_{r}=3.55$ and $\tan\delta=0.0027$. Experimental results show that the antenna can produce up to 30° of beam-steering across the band.
