Abstract

Carrier phase measurement in RFID and other wireless communication devices can be used in general for ranging, angle of arrival detection and localization. Modern ISO 18000-6C RFID readers perform fully coherent demodulation, detect the signal phase and deliver it to the user. However the presented phase is π-periodical and not 2π. This is caused by the symmetry of the received signal and the phase-recovery methodology used. In this paper we introduce a phase-recovery method retrieving a 2π-periodical phase. A larger ambiguity range for the phase measurement is beneficial for all phase-based localization methods: it allows, for example, increased array-element spacing in angle-of-arrival detection methods; and improves the resolution for imaging methods. © 2013 IEEE.
