Abstract

Acoustically actuated mechanical ME antennas based on MEMS technology have been demonstrated to be one of the most effective technologies to miniaturize antennas. In this work, a new high-gain ultra-compact magnetoelectric antenna design based on FBAR for Portable RF wireless communication is introduced. This ME antenna is driven by acoustic waves and its fabrication is mainly based on the MEMS standard process. Due to the strong magnetoelectric coupling effect of magnetoelectric composites and the acoustic wavelength being much shorter than the EM wavelength at the same frequency, a high antenna gain of -15.77 dBi is achieved at the frequency of 2446 MHz. The effective electromechanical coupling coefficient and phase quality factor of the fabricated device are calculated as 1.3% and 172, respectively. This high-gain ultra-compact ME antenna takes a step forward for FBAR-based ME antenna research.

用于便携式射频无线通信的高增益超紧凑 ME 天线设计

基于MEMS技术的声驱动机械ME天线已被证明是天线小型化最有效的技术之一。本文介绍了一种基于FBAR的便携式射频无线通信高增益超紧凑磁电天线的设计。该天线由声波驱动，其制造主要基于MEMS标准工艺。由于磁电复合材料具有很强的磁电耦合效应，且声波波长远短于同频率下的电磁波长，在2446 MHz频率下获得了-15.77 dBi的高天线增益。计算得到器件的有效机电耦合系数为1.3%，相位品质因数为172。这种高增益超小型ME天线为基于fbar的ME天线研究向前迈进了一步。
