Abstract :
A bulk acoustic wave (BAW) based multiferroic antenna structure is proposed, to overcome the platform effect associated with low-profile antennas. Numerical analysis based on the one-dimensional finite-difference time-domain (FDTD) technique, as well as analytical analysis is applied. The dynamic stress profile within the resonator and the radiation quality factors (Q factors) are simulated. In addition, the radiation of the electromagnetic waves acting as a damping load to the acoustic resonances is represented. The agreement between the numerical solutions and the analytical solutions provides a validation to the operating principle of the proposed antenna.
