This research project implements a calibration-free detection technique that uses dual-polarized interrogation for chipless radiofrequency identification (RFID). To detect the ID on a chipless RFID tag, the literature is used to evaluating radar cross sections (RCS), which requires multiple measurements to remove the clutter. This study implements the dual-polarized interrogation to improve this limitation. We construct a system that uses the dual-polarized interrogation over 2.0-4.0 GHz, which is mapped to 216 different information. These tags are tested in real-world environments. Our results show that the proposed technique has relatively high design sensitivity, but these tags can be successfully detected using only one sample.
