Abstract—In this paper, we propose a novel design method of antenna for 3D RFID access control. This method can simple design a three dimensional RFID access control by only using the analysis for near-field magnetic coupling incorporating transformer inductance coil system. This system uses three overlapping loop antennas in walk-through gate. Simulation is given to explain the overlapping sequence of the three antennas.
