Development of Low Frequency Acoustics Driven Antennas

Low frequency antennas are widely used for long-distance wireless communications including military communication, frequency modulation (FM) broadcasting and amateur radio. Herein, two types of wideband electrically small antennas for low frequency applications are briefly reviewed. To further improve the performance of the low frequency antenna, the acoustics driven very low frequency antenna is developed and its theory is introduced to discuss the development of the acoustics driven low frequency antennas.
