Prof. Alessandra Costanzo

For a future of ubiquitous networks of wireless sensors, one of the main challenging tasks is the wireless powering of a multitude of small devices and machines to allow truly perpetual wireless-powered communication (WPC). This webinar first describes possible solutions for the RF architectures of transmitting and receiving sides for battery-less scenarios, showing how multi-domain design techniques, combining EM theory and numerical simulation with nonlinear circuit design can provide reliable system implementations; secondly the effective exploitation of such systems is shown through some significant applications, such as high precision localization (centimeter-level ) and tracking, adopting UWB communication, and predictive maintenance in machineries and industrial plants scenarios exploiting low-energy communications. The design challenges for both the transmitting and receiving subsystems are presented together with the performance achievements in real scenarios.

Alessandra Costanzo (A’99–M’02–SM’13) is a full professor at the University of Bologna, Italy. Her research activities are dedicated to CAD algorithms for multi-domain co-design and modeling of active nonlinear microwave/RF circuits. Recently she has proposed novel solutions for energy autonomous RF systems based on the wireless power transmission, adopting both far-field and near-field solutions, for several power levels and operating frequencies. She has authored more than 250 scientific publications on peer-reviewed international journals and conferences and several chapter books. She is past-chair of the MTT-26 Committee on Wireless Energy Transfer. Since 2016, she has been the Steering Committee Chair of the new IEEE Journal of Radio Frequency Identification. She is the MTT-S representative and Distinguished Lecturer of the Council on Radio Frequency Identification (CRFID). She has been Associate Editor for the IEEE Transactions on Microwave Theory And Techniques.
