In living organisms, the magnetic field signals generated by the bioelectric currents of muscle cells and nerve cells carry information such as physiological processes and pathology, and accurate acquisition of the magnetic field information is of great significance for physiological signal monitoring. This paper presents an acoustic wave mediated antenna that can be used for physiological magnetic field signal monitoring. The acoustic wave mediated magnetoelectric antenna proposed in this paper is orders of magnitude smaller than the size of the most advanced small antennas available today. Recent experiments have verified the feasibility of the ME antenna through experimental tests. The electromagnetic wave coupling effect between the electromagnetic wave and the bulk acoustic wave can realize the transmission and reception of the electromagnetic wave by the antenna. In this paper, the working principle of ME antenna is theoretically deduced, and the magnetic-force-electrical coupling of the antenna is simulated and the structural design is optimized. The aim is to further improve the performance of the antenna.
