Abstract

Using a hybrid method of mm-wave frequency scanning and pattern-recognition techniques, a highly accurate chipless Radio Frequency Identification (RFID) system in 60 GHz free spectrum has been developed. It contains high encoding capacity chipless tag based on alphabetic characters printed onto a low-cost substrate. The individual tag is scanned with a pair of orthogonally polarized horn antennas in a few view angles within the 57-64 GHz band. The resulted cross-polar backscattered signal is processed to enable feature learning and classifications using different networks, such as Support Vector Machines (SVMs), K-Nearest neighbors (KNNs) and Ensembles. This method yields > 95% reading accuracy which demonstrates great improvement in many low-cost chipless tag applications.
