Chipless Sensing System Compliant With the Standard Radio Frequency Regulations

The aim of this paper is to develop a framework of a chipless wireless system for sensing in compliance with the standard international regulations. The proposed approach offers a solution to solve the main difficulty met for the deployment of chipless systems that require specific readers (based on non-standardized large frequency bands and specific signal waveforms). The possibility of interrogating chipless sensors in the regulated bands is demonstrated. The concept is introduced from several chipless sensor solutions, including specific sensors (here sensors for detecting temperature then motion), and the associated reader architecture built as a prototyping platform based on universal software radio peripheral (USRP).
