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.

“…The ambient signals received by the energy harvester are typically weak. The Federal Communications Commission (FCC) limits the isotopically radiated power (EIRP) to 36 dBm in this band [33]. After propagation losses these signals are attenuated to approximately 10 dBm and -10 dBm for distances of 0.2 m and 2.5 m respectively, assuming a line of sight (LOS) link [33].…”

This paper presents a compact backscatter modulator tag operating at 1.76 GHz. The modulator is composed of a series combination of a variable resistor and a varactor. These components modulate the backscatter signal by adjusting the input impedance or input reflection coefficient. A gallium nitride (GaN) on silicon carbide (SiC) high electron mobility transistor (HEMT) is adopted to implement the variable resistor. The modulator can support a variety of modulation schemes without increasing the size and design complexity. The tag can be continuously powered through ambient RF energy in the 2.45 GHz frequency band. A differential rectifier harvests RF energy to power a microcontroller eliminating the need for a battery. Experimental results show that the modulator can support 16-QAM with an error vector magnitude (EVM) of 1.73%. The measured RF to DC power conversion efficiency (PCE) of the energy harvester is 57.1% at a received power of 1.7 dBm.

“…The chosen diode must be adapted to high frequency and have low power consumption since the input is low. As mentioned in [12], the Schottky diode SMS 7630 fabricated by Skyworks company has good low-power performance and thus is chosen to be used with an input below -20dBm.…”

In this paper, a complete RF to DC wireless power transmission implantable rectenna system is presented. For simplicity, an external half-wave dipole at Industrial, Scientific and Medical bands (ISM 902.8-928 MHz) is selected as an energy emitter from outside human body. An embedded circular dipole antenna receives the energy and then converts it to DC power by a rectifying circuit. The structure of the system is discussed in details. Finally, the rectifying efficiency and the global system's efficiency are examined for different external antenna to human body distances, different embedded depth and various levels of circuit's input power.
