Abstract

A method and system for reading one or more chipless RFID tags in the extremely high frequency band is provided. The method and system includes determining the background noise and providing a tag in a reader, the tag providing a backscattered signal. The backscattered signal is received from the tag at one or more locations and the number of patterns in the tag is determined. The frequency pattern is then provided to a machine learning system to learn or decode the pattern, using merely frequency response or frequency response and constructed image of the tag.
