Abstract

We present the results of a new Ultra High Frequency (UHF) Radio Frequency Identification (RFID) system using multiple, distributed, phased array antennas for interrogating RFID tags over wide areas. The system makes use of signals multicast over two steerable antenna arrays with phase diversity to overcome fading. The system is compared to two other methods for driving the two arrays; one with the more widely used time division multiplexing and beam steering, and another with multicast signals and beam steering but without phase diversity. It is shown that the new system outperforms both of these in terms of tag RSSI and tag read success rate. The results are validated using a 3D field-based simulator, which enables visualisation of the power distribution in the field of interest.
