本文提出了一种由液态金属（共晶镓铟）制成的连续可调谐微带贴片天线。通过计算机仿真验证了天线的概念和设计。天线能够以连续的方式重新配置其工作频率。提出的设计包括一个微带贴片，该贴片通过孔径耦合激发。EGaIn液态金属包含在聚二甲基硅氧烷（PDMS）衬底内形成的微流控通道内。频率调谐是通过改变通道内的流体量来改变天线的电长度来实现的。仿真天线提供约104%的频率调谐范围和105%的总可用频谱（S11 <−10 dB）。天线可以在3.21 GHz到10.12 GHz之间调谐。最大实现增益为6.9 dBi，总效率为82%。
This paper presents a continuously tunable microstrip patch antenna formed from liquid metal (eutectic gallium indium). The concept and design of the antenna have been validated through computer simulation. The antenna is capable of reconfiguring its operating frequency in a continuous manner. The proposed design consists of a microstrip patch which is excited via aperture coupling. The EGaIn liquid metal is contained within a microfluidic channel which is formed within a polydimethylsiloxane (PDMS) substrate. Frequency tuning is achieved by altering the amount of fluid within the channel to vary the electrical length of the antenna. The simulated antenna provides a frequency tuning range of approximately 104% and a total usable spectrum (S11 < −10 dB) of 105%. The antenna can be tuned from 3.21 GHz to 10.12 GHz. The maximum realized gain is 6.9 dBi and the total efficiency is 82%.
