A novel very low frequency (VLF) communication system using one pair of magnetoelectric (ME) antennas has been proposed. The ME antennas are strain-mediated acoustic resonators operating at their electromechanical resonance in the VLF band. The measured near-field radiation pattern reveals ME antennas are equivalent to dipole antennas. The magnetic field radiated by the ME transmitter has been predicted along with distance ranging from 1 mm to 100 km. The measured magnetic field distribution coincided well with the prediction, and the maximum communication distance of 120 m has been achieved. With 80 V driving voltage, the power consumption of the ME transmitter has been measured as 400 mW. Furthermore, the direct antenna modulation (DAM) has also been successfully demonstrated on the ME antennas.

一种基于声驱动磁电天线的便携式甚低频（VLF）通信系统

已经提出了一种使用一对磁电 (ME) 天线的新型甚低频 (VLF) 通信系统。ME 天线是应变介导的声学谐振器，在 VLF 频带中以其机电谐振运行。测得的近场辐射图显示 ME 天线等效于偶极天线。ME 发射器辐射的磁场已被预测，距离范围为 1 毫米到 100 公里。实测磁场分布与预测吻合较好，已实现最大通信距离120 m。在 80 V 驱动电压下，ME 发射器的功耗测量为 400 mW。此外，直接天线调制 (DAM) 也已在 ME 天线上成功演示。
