Modeling and Optimization of VLF Piezoelectric Antenna Towards Lower Frequency

This work marks the first performance analysis of structure optimization of piezoelectric disc antenna and its impact on the characteristics and performance. Compared with the state-of-art technology, three distinctive advances have achieved: (a) first demonstration of central perforation on piezoelectric disc to further reduce the resonance frequency of the acoustically driven antenna; (b) simulation results and discussion of the characteristic and performance of the proposed design; and (c) an outlook and feasibility analysis of spaceborne low-frequency telecommunication with acoustically driven antenna on satellites.
