Radiation enhancement in shear horizontal surface acoustic wave driven magnetoelectric antenna
Magnetoelectric (ME) antennas driven by shear horizontal surface acoustic waves (SH-SAWs) exhibit significant potential for miniaturized high-frequency systems owing to their structural simplicity and acoustic–magnetic coupling characteristics. In this work, we demonstrate an SH-SAW driven ME antenna based on a 42° YX-LiTaO3/FeGa heterostructure, achieving a reference gain of −18.4 dBi and radiation efficiency of 0.52%. Through bias magnetic field modulation, we experimentally observe enhanced coupling between shear horizontal mode and magnetization of FeGa film. These findings provide a method for optimizing radiation efficiency in acoustically driven ME antennas, for the design and performance improvement of ME antennas.
