Radio frequency (RF) energy harvesting and wireless power transmission (WPT) technologies have attracted significant interest in wireless applications and RFID systems. This article provides a historical overview, discusses technical challenges, and presents recent advances in these technologies.
Radio frequency (RF) energy harvesting and wireless power transmission (WPT) technologies -both near-field and far-field-have attracted significant interest for wireless applications and RFID systems. We already utilize near-field WPT products in our life and it is expected that RF EH and far-field WPT systems can drive the future low-power wireless systems. In this article, we initially present a brief historical overview of these technologies. The main technical challenges of rectennas and WPT transmitters are discussed. Furthermore, this paper presents the recent advances on the development of these technologies, including the possibility of powering RFID systems through the millimeter wave power from 5G networks, the trends in flexible rectennas design and the technological developments on the simultaneous wireless information and power transfer (SWIPT).
