• The UHF RFID Radio Szenario • Passive UHF RFID Ranging/Positioning Methods • Positioning with Multiple Antennas • A new Time-of-Flight Ranging Method for Passive UHF Tags • Summary ContentsAbstract— In this paper, we give an overview of spatial identification (determining position and velocity) of modulated backscatter UHF RFID tags using RF phase information. We describe three main techniques based on PDOA (Phase Difference of Arrival): TD (Time Domain), FD (Frequency Domain), and SD (Spatial Domain).

In this paper, we present an accurate passive RFID localization technique, which can easily be implemented and deployed in various environments, coupled to a complete human activity recognition model. RFID UHF bands diverge in different countries and include ranges between 860 MHz and 960 MHz. Cheaper RFID transponders can be developed by increasing the read range, enhancing the anti-collision algorithms and also by adding new functionalities such as tag localization and sensors attachment.We were able to localize the transponders with a mean accuracy of 0.21 m using three antenna array positions for triangulation in a 3 m × 3 m room. Considering that the introduced principle for tracking the position of a UHF RFID tag with the aid of beam-steering is based on the pattern formation, it is essential for the tracking system to provide consistent pattern characteristics over a desired scan angle span.
This paper has shown a new method of evaluating UHF RFID DoA estimation systems by utilizing a hardware in the loop setup to simulate RFID targets. The signal models used in the received signal simulation have been developed and the need for spherical wave propagation models has been examined.In this paper, a new approach for estimating the position of a passive UHF RFID tag is presented. Instead of using well known angle-of-arrival (AoA) techniques, a transmitter beamforming method, called ‘Angle-of-Activation’ (AoAct) is applied.
