提出了一种方向图可重构的液态金属磁电偶极子天线。该天线由铜的磁电偶极子和聚碳酸酯(PC)的液态金属通道结构组成，在磁电偶极子的中间放置一条Г馈电条用于耦合馈电。所提出的方向图可重构天线主要使用液态金属在天线周围制作寄生单元。每个液态金属寄生单元被分开控制，并通过塑料管与底部的储液罐相连，通过改变寄生单元的排列，可以实现对应于(θ，Φ)max=(0°，0°)，(±32°，0°)，(±30°，±30°)，(±32°，±58°)，(±28°，±86°)的15种状态的图案重构。该天线的主要工作频段为2-2.5 GHz。当天线工作状态发生变化时，增益始终大于6分贝，效率大于70%。该天线可以覆盖部分通信频段，可用于未来的通信。
We propose a pattern-reconfigurable liquid metal magneto-electric dipole antenna. The antenna is composed of a magneto-electric dipole made of copper and a liquid metal channel structure made of Polycarbonate (PC), one Г-Type feeding strip is placed in the middle of magneto-electric dipole for coupling feeding. The proposed pattern-reconfigurable antenna mainly uses liquid metal to make parasitic units around the antenna. Each liquid metal parasitic unit is controlled separately and connected with the liquid storage tank at the bottom through a plastic tube, by changing the arrangement of parasitic units, the pattern reconfiguration of 15 states can be realized corresponding to (θ, Φ) max = (0°, 0°), (±32°, 0°), (±30°, ±30°), (±32°, ±58°), (±28°, ±86°). The main working frequency band of the antenna is 2–2.5 GHz. When the working state of the antenna changes, the gain is always higher than 6 dB and the efficiency is greater than 70%. The proposed antenna can cover part of the communication frequency band and can be used for future communication.
