UHF RFID Portal Performance Optimization & Evaluation Method

UHF RFID portal, usually composed by two or three antennas which connect to one reader. However, RFID system designers often feel puzzle about the antenna deployment since they have no idea of how high or which angle the antenna should be or how many antennas should be deployed. An antenna deployment optimization and evaluation method was proposed in this paper, which can guide the designer to optimize RFID portal system deployment, and it can also help them evaluate their portal performance. The biggest advantage of the method is it's effect and easy to use.
