“…The large EIRPs allowable by the FCC in the licensed 5G bands have stimulated innovations in the design of mmwave-enabled powering and backscattering communications solutions. While some works focused on improving the rectification efficiency or sensitivity via the design of Schottky diode-based rectifiers [70], [95], [142] or Complementary Metal-Oxide-Semiconductor (CMOS) systems [143], [144], others focused on solving a fundamental problem that occurs at mm-waves: the inability to achieve high gains with large antenna array structures while maintaining a wide angular coverage [141]. To better explain the need for such capabilities, we show in Fig.…”

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).

In this paper, the evolution and milestones of RFEH and related breakthroughs over the years are reviewed and presented. The review begins with an overview of the surging energy crisis due to the increasing demand for wireless communication devices. Furthermore, the RFEH mechanism that discusses the frequency bands utilized, the near field, and the far field propagation are also presented. Various rectification techniques in CMOS RFEH, from the fundamental rectification method to cross-coupleddifferential-drive (CCDD), are also examined and discussed. The performance is gauged through harvested output DC voltage and the power conversion efficiency (PCE) as well as the RF input power sensitivity. An assessment on the non-CMOS RFEH that includes the Schottky diode and Rectenna is also concisely described to analyze their contribution to RFEH's performances enhancement. Finally, a special highlight of the 5G RFEH in mmWave is provided in the presentation of this work as an ongoing future solution to reduce the electronic circuit's battery dependency. The pros and cons of all the presented RFEHs are summarized and discussed as well. Continuous research and development activities are extensively being executed in developing a system that could ultimately solve the world's energy crisis and RFEH seems to be a revolutionary approach.

A novel 60 GHz RF/DC power harvesting system is presented. The system consists of RF to DC rectifier and a DC/DC Buck converter based on constant ON/OFF time (COOT) control. The rectifier has a structure of voltage doubler, but employs diodes that have lower parasitics compared to those of the standard MOSFET diodes, resulting in improved power conversion efficiency. The peak efficiency of the rectifier obtained with the extracted parasitics for the output power of 1 mW is about 25%. In order to keep the output voltage of the system to 1.2 V, the COOT control in the Buck converter is used. COOT control has much better efficiency at low output powers compared to the PWM systems. For correct operation of the COOT control, auxiliary sub-blocks: a low power high-speed comparator, a hysteresis comparator, and a high-speed voltage reference are designed and presented. The maximum switching frequency in the Buck converter is about 100MHz and the whole control system has very low static power consumption. The efficiency of the overall system for the output power of 1mW is about 21%. The system is designed in 65 nm CMOS technology.
