Abstract

Radio Frequency Identification (RFID) tags are gaining popularity in sensing applications. Common implementations rely on backscattering digitally encoded sensor data from an RFID tag to a reader. This paper discusses a unique capability of RFID technology to detect objects in a tag´s near vicinity by observing trends in the magnitude and phase of backscattered signal, irrespective of the information encoded in the data. Computational results and measurements are presented, and demonstrate how to improve sensitivity for object detection near a tag.
