Abstract

Abstract

Very low frequency has great potential for long distance signal transmission and military communications due to its low propagation loss characteristics. Magneto-Electric (ME) antennas, based on the acoustic resonance principle, can push the limits of size and are easily impedance matched, offering unique advantages for transmission in the very low frequency band. Based on this, a new ME antenna system consisting of a transmitting antenna of P/T/P structure and a receiving antenna of T/P/T structure is designed. The structural pattern of the antenna in receiving/transmitting electromagnetic waves is analyzed based on the magneto-mechanical coupling model. The magnetic field distribution of the antenna in the near-field range is investigated based on the radiation model. An experiment on the transmission/receiving of ME antennas in the very low frequency band is realized with acoustic wave mediated excitation. Experimental results indicate that obtained at resonant frequencies, the ME transmit/receive antenna is improved by 82.6% in output voltage and by 42.2% in communication range before the structure optimization compared to after the optimization when the piezoelectricity ratio is 0.66 and 0.34, respectively. Magnitude higher radiation efficiency is improved by three orders compared to the same size electric small antenna. Modulated communication with a transmission rate of 5 bit/s is possible and the performance of the antenna is improved based on structural optimization.
