In order to solve the current traditional underground wireless communication technology using high path loss of electromagnetic waves, with the reference channel and other issues, this paper designed a magnetic induction transmission system front end:using magnetic inductance coil as the antenna and magnetic induction to transfer data. This design dedicated for data transmission in the soil medium, the transmission performance is stable and high efficiency. This is well positioned to meet the demand for underground transmission, greatly improving efficiency.
