A Depolarizing Chipless RFID Tag for Robust Detection and Its FCC Compliant UWB Reading System

Abstract : A new chipless RF identification (RFID) tag design is presented in this paper to ease the detection of items in a real environment. For this purpose, we present multiple scatterers able to depolarize the incident wave to create a response in the orthogonal polarization. Measurements in anechoic chamber and in a real environment, when the tags are positioned on dielectric and metal objects, show their higher detection capability. For the first time, a study on the technique to increase the detection area with a simplified calibration step is carried out. This makes possible the detection of the tag on objects of various sizes and compositions, which is required in the majority of RFID applications.
