Radio Frequency Identification (RFID) is expected as a promising solution that bring about revolution in the supply chain management. On the other hand, RFID has an issue on read reliability due to radio propagation. For achieving a good read success rate, however, it is necessary to understand indoor radio propagation environment with surrounding materials that reflect radio waves and generate standing waves. In this paper, we analyze RFID read success rate in metal shelf environment through FDTD simulation. In order to improve the read success rate, we propose a reader/writer (R/W) beam scanning and repeated transmission scheme with a moving conductor. By displacing the conductor in the vicinity of R/W antenna, null position caused by the standing waves is moved. Then, read success rate can be improved by repeated transmission and selection combining. It is confirmed from the simulations that the read rate is greatly improved by the proposed scheme. |
