  • 摘要: 甚低频段由于低传播损耗特性,在远距离信号传输及军事通信方面有巨大潜力。传统天线庞大物理尺寸以及复杂网络匹配限制了低频天线通信的发展。磁电(ME)天线基于声波谐振原理可以突破尺寸极限且易于阻抗匹配,在甚低频段传输具有独特优势。基于此设计了P/T/P结构的发射天线和T/P/T结构的接收天线组成的新型ME天线系统。依据磁机电耦合模型分析天线在接收/发射电磁波时的规律;依据辐射模型研究近场范围内天线磁场分布情况;以声波介导激励,实现ME天线在甚低频段的发/收通信实验。实验得到在谐振频率下,ME发射/接收天线在压电占比分别在0.66, 0.34时,结构优化前较于优化后输出电压提升82.6%,通信距离提升42.2%;相较于同等尺寸电小天线辐射效率提高3个数量级;可实现传输速率为5bit/s的调制通信,依据结构优化实现了天线性能的提升。
