【摘要】 本文提出了一种基于电毛细力驱动的液态金属频率可重构天线。基于电化学反应在毛细力的作用下实现液态金属的移动,实现印制铜天线的通断,进而调整天线的辐射振子的长度L。L有四种不同的长度,在这4种状态下,阻抗匹配良好,天线可获得2.24～4.80 GHz的工作频带。该设计的天线具有全向辐射的特性,最大的辐射增益为3.93 dBi。更多还原

【Abstract】 In this paper,a liquid metal frequency-reconfigurable antenna driven by electric capillary force is proposed.The movement of liquid metal is realized under the action of capillary force through electrochemical action,and then the on-off of the printed copper antenna is realized,and the overall length L of the antenna is adjusted.L has four different lengths.In these four states,impedance matching is good,and the antenna can obtain a working frequency band of 2.24-6.04 GHz.The antenna of this design has the characteristics of omnidirectional radiation,and the maximum radiation gain is 3.93 dBi.更多还原
