A dual-band retrodirective reflector array on paper utilizing Substrate Integrated Waveguide (SIW) and inkjet printing Technologies for Chipless RFID Tag and Sensor Applications

In this paper, the dual-band retrodirective reflector array using Substrate Integrated Waveguide (SIW) and inkjet-printed technologies on paper, for operability around 3.6 GHz and 5.8 GHz is proposed. It offers the versatility of multi-band retrodirective designs potentially covering numerous RFID interrogation, sensing and communication bands.
