Vibration-Induced Noise in Extremely Low Frequency Magnetic Receiving Antennas

IEEE Antennas and Wireless Propagation Letters, 2021
The extremely low frequency magnetic antennas are widely used in geophysical exploration, marine electromagnetic detection, and other applications. However, the slight vibration of the antenna platform will cause extra antenna electromagnetic noise. In this letter, the electromagnetic noise of the magnetic antenna caused by vibration is simulated under

A Method on Underwater Extremely Low Frequency Atmospheric Noise

Applied Mechanics and Materials, 2013
On the basis of low-pass characteristic of the ocean in extremely low frequency (ELF) band , which makes the atmospheric noise distort and signal to noise (SNR) of the receiver worse, magnitude-frequency and phase frequency characteristic of the ocean in ELF band were researched.

A very low noise preamplifier for extremely low frequency magnetic antenna

Journal of Semiconductors, 2013
Besides the electrode-pair antenna, the magnetic antenna is also used for the extremely low frequency (ELF) submarine communication. To receive the weak ELF signals, the structure of a small sized magnetic antenna determines its specific electrical characteristics.
