Acoustics Driven Antennas for SLF Communication Applications

A consideration for super low frequency (SLF) antenna design is proposed on the basis of the piezoelectric material, which is to reduce the size of traditional SLF antenna designed using metal. The proposed SLF antenna design is realized by using voltage to excite different modes of the piezoelectric material to give mechanical waves and then to produce electromagnetic wave. The proposed SLF antenna has a very compact size of hundred millimeters. Different materials are investigated to discuss the effect on the resonance frequency, while the different modes are also analyzed to control the resonate frequency. The results show that the proposed SLF antenna can be flexibly designed for implementing at expected acoustic frequency bands.
