Wireless Sensing

Our research explores wireless sensing through antenna design, passive wireless technologies and RF measurements for the Internet of Things (IoT). Applications include structural health monitoring, precision agriculture, and identification and tracking in retail and supply chains. A key focus is chip-based and chipless RFID sensing. Chip-based RFID tags combine an integrated circuit for data storage with an antenna for wireless communication. Chipless designs encode information in their electromagnetic response, offering opportunities for low-cost, lightweight sensing without an integrated circuit or battery. We study how antenna and sensor structures can support both identification and sensing, with attention to their electromagnetic response and practical implementation. Ultra-wideband (UWB) antennas can form part of the sensing device or serve as the RF front end of an RFID reader.
