Abstract

A novel identification algorithm of chipless RFID tags by using an eigenmode analysis based on the SVD-decomposition, in conjunction with a signal-processing technique is presented. We start by extract a dominant eigenmode of the tag and show that we can significantly enhance the capability to carry out the scatterer recognition by exciting the tag with a transmitter antenna array with an excitation coefficient associated to the dominant mode. Later, a signal-processing algorithm is proposed to identify a tag based on the signals received by an array including fields scattered from the direct coupling between the transmitter and the receiver antennas in presence and in absence of the tag in the reader area. In addition, an identification vector is processed to detect the presence of multiple chipless tags simultaneously with range information and to identify a particular tag.
