| description | Abstract This paper addressed the miniaturization requirements of low-frequency electromagnetic communication systems. A magnetic field model was proposed to precisely calculate the magnetic characteristics of the magnetic pendulum mechanical antenna. Firstly, the magnetic force experienced by the rotor permanent magnet within the stator permanent magnet and the driving coil magnetic fields is analyzed, and a dynamic model of the magnetic pendulum mechanical antenna is established, followed by the development of the magnetic field model of the magnetic pendulum mechanical antenna. To validate the accuracy of the magnetic field model, a prototype of the magnetic pendulum mechanical antenna was fabricated using 3D printing technology. The average error of mechanical antenna’s magnetic field based on experimental measurement and theoretical calculation is 5.1%. This result confirms the consistency between the experimental and theoretical magnetic field model results. Finally, the magnetic characteristics of the magnetic pendulum mechanical antenna were analyzed, providing theoretical support for the design of mechanical antennas. |
