Study of an Accurate Phase-Based Localization Method for Semi-Passive RFID Tags

摘要

This paper presents a simulation model for a novel method of indoor localization that is based on the phase difference between elements in an antenna array. The localization system is used to identify the position of a semi-passive radio frequency identification (RFID) tag. For proof of concept, a set of experiments for phase measurements are designed using a commercially available transceiver. Results demonstrate that the proposed simulation model comparatively provides an accurate estimation as well as assessment tool of phase measurements for indoor localization application.
