This paper introduces a two-dimensional localization system for passive UHF RFID transponders based on phase-of-arrival evaluation of the backscattered tag signal. A multiple-channel system, where alternately one path is configured as a transmitter and the remaining paths work as receivers, is used to permit the position estimation. To improve localization(More)
A multi-reader system is presented which is capable of increasing the working range of passive RFID systems. This gain in range is obtained by using constructive superposition of the readers' RF waves. A coherent multi-reader demonstrator system has been designed that consists of two reader units and one central unit. The demonstrator system operates in the(More)
