Detection, Identification, and Localization in Chipless RFID Systems

The scattered signal from chipless RFID tags is received by the receiving antenna and transferred to the reader. In the reader, some information such as the location and ID of the tags should be extracted from the received signal. In applications where multiple tags are present in the reader area, we need to first distinguish the tag’s responses from the responses of the background objects around the tag. After the detection process, the locations and IDs of the tags should be extracted, the process of which comprises the localization and identification process in the reader.
