Abstract
Radio Frequency Identification (RFID) has been used to improve services such as inventory management and behavior analysis in recent industries. Since these services require tracking the movement of objects where an RFID tag is attached, the direction estimation scheme for RFID tags has been attracting attention. Conventional estimation schemes require a large space for antenna installation or assume expensive small antennas, which poses a challenge for implementation in the field. This paper evaluates the performance of the proposed direction estimation scheme for several types of RFID tags because the authors have conducted the initial evaluation. Since the proposed scheme uses an angled single antenna, it should be a valuable scheme in practical service if the proposed scheme generally works for several types of RFID tags. The proposed scheme focuses on the features of change in Received Signal Strength Indicator (RSSI) and phase value caused by an angled antenna. The evaluation result shows that the proposed scheme can estimate the direction of movement accurately for multiple types of tags.
