| 摘 要： | 提出一种新型的液态金属频率可重构天线设计方法。以对称振子天线为原型,采用镓铟液态合金(EGaIn)为辐射元,将其包裹在微流体通道内。在天线适当位置开口添加绝缘片,呈断路状态;撤掉绝缘片,利用液态金属自我修复性能,加热挤压切口使其愈合,呈通路状态;通过调节绝缘片的位置实现1.6~3.0 GHz频率范围内的重构,并通过曲线拟合提出了适合该天线的工作频率估算公式。仿真结果表明天线具有良好的带宽、阻抗特性,并保持较高增益,辐射性能良好。

| Abstract: | A new technique of fluidic metal frequency-reconfigurable antenna design was presented.Used dipole antenna as prototype,EGaIn embedded in micro fluidic channels as radiating element.Cut the antenna and add one insulation piece at proper position,an open circuit was created.Based on self-heal of fluidic metal antenna,heat and press the cut,a break over was created.The antenna operates at frequency region 1.6~3.0 GHz by adjusting the insulation piece’s position.A curve-fitting frequency-estimation formula was given.The simulation results show that the antenna features good bandwidth,impedance matching,and keeps a high gain,good radiation performance. |
