Analysis of Electromagnetic Wave Propagation in Out-door Active RFID System Using FD-TD Method
In recent years, RFID systems have received much attention in security, logistics and medical fields. However, most of these systems are used at in-door and the RF tags are passive tags that are controlled by reader. We consider to use active RFID system of very weak UHF effectromagnetic waves at out-door. In this paper, we describe the characteristics of effectromagnetic wave propagation by RF tags using FD-TD method. In transmit and receive points of the weak effectromagnetic wave, receive characteristics are influenced by the established environment. We consider the road models as this environment. RF tags are carried by the human on the road, and the readers are installed on the effectric pole and connected to the cable network. As out-door models, we consider road models of three types, the straight road, the T-type road and the cross road.
