In order to explore the influence of design parameters on the lightning low frequency magnetic field detection antenna, this paper designs a lightning low frequency magnetic field detection antenna. Firstly, based on the LCR analyzer, the influence of the antenna length, the number of the wire and the diameter of the magnetic rod on the resistance, capacitance and inductance of the antenna is analyzed. Secondly，a test platform was constructed using Helmholtz loop coils, and then the platform was used to perform sensitivity tests on the reception performance of ferrite antennas wound. And the effects of antenna length, the number of wires and the diameter of the magnetic rod on the receiving performance of the antenna were discussed. Finally, the research conclusions are as follows: Increasing antenna length can increase the antenna bandwidth, but it will reduce the frequency response value of the antenna. However, increasing the number of wrapped wires is the opposite. Increasing the magnetic rod diameter can increase the frequency response value and the bandwidth, but it will make the size of the antenna larger. So, the selection of the antenna length, the wires number and the magnetic rod diameter needs to be considered in a compromise. This paper analyzes the influence of various parameters on the lightning low-frequency antenna, which has a certain reference value for improving the lightning detection ability.
