Abstract
A simplified three-dimensional simulation model of the magnetoelectric (ME) antenna based on thin-film bulk acoustic wave resonator (FBAR) is proposed in this paper. Based on this model, the effect of the radius ratio of the magnetostrictive layer to the piezoelectric layer on the performance of the FBAR ME antenna is studied. When the radius ratio is 0.8, the ME antenna has the optimal comprehensive performance. The ME antenna resonates at the frequency of 1.6 GHz while providing a peak return loss of 22.22 dB and 10 dB-bandwidth of 6.2 MHz. Based on the ME antenna, the influence of the substrate clamping effect on the radiation performance is studied. The resonant cavity induction increases the radiation efficiency of the ME antenna by 461 times. The ME antenna’s radiation pattern is similar to that of a magnetic dipole.
