mm-Wave Chipless RFID Tag for Healthcare Applications

Abstract

The work proposes the use of mm-wave chipless tag to be used in healthcare applications. A chipless tag at 24 GHz based on a cross-polarized Van Atta retrodirective array has been designed with the aim to show the practical feasibility of the proposed system. Numerical results of a small array made of 6 elements show a good RCS level that makes that kind of chipless tag promising for indoor healthcare monitoring.
