Abstract

© 2017 IEEE. How to achieve desired accuracy of RFID localization is challenging for high dynamic and sparse environments, especially for anisotropic RFID tags. We introduce a new method of measuring location of the active RFID tags in three-dimension space to improve localization accuracy. This research (i) provides directional signal-distribution models for both horizontal and vertical orientation of anisotropic active RFID tags, (ii) improves an attenuation model of RF signal with transmitting distance for real applications and (iii) deduces a spatial signal attenuation model of an active RFID tag (SSAM). The accuracy of the model is less than 4 dB for more than probability 50% based on the experimental results, location accuracy is up to 1 meter in 400 m2 experimental field.
