Automated guided vehicles (AGVs) have been largely used in manufacturing and supply chain management. With the development of Auto-ID technologies like radio frequency identification (RFID), AGVs' positioning could be enhanced. This paper demonstrates using magnetic field lines in the AGVs for precise coverage locating based on the errors' suppression positioning method. Dolph-Chebyshev antenna array is used to enable AGVs with more precise location implementation. It is observed that the far-field active RFID system positioning accuracy is higher, the movement is more stable, and the fluctuating rate is smaller.
