Abstract :
A new methodology, based on short-time-matrix-pencil-method (STMPM) is proposed for separating IDs of multiple chipless RFID tags presented in the main beam of the reader antenna. In this approach, turn-on times of the complex natural resonances (CNRs) of the tags are employed as the roundtrip times of the tags from the antenna and by marking the tags with some specific resonances in addition to ID poles, the interfering poles from background objects and antennas in the reader zone are distinguished from the tag poles.
