“…The practical EH model uses the diode rectifier circuit to achieve the RF-to-DC conversion. The diode saturation EH model, obtained by fitting the experimental data, has high reality and is widely adopted in both the wideband [41]- [43] and the narrowband [44]- [46] IDET systems. The saturation EH model can be expressed as [42] Θ (P in )…”

When wideband signals propagate in a richscatterer environment, we obtain abundant resolvable multiple transmission paths to form a number of virtual antennas. Therefore, substantial spatial gain can be attained by carefully waveforming in all these resolvable transmission paths without additional antennas. This resultant spatial gain is then exploited for improving the performance of integrateddata-and-energy-transfer (IDET) from a single transmitter to multiple receivers. We aim to maximise the downlink fairthroughput and sum-throughput, while satisfying the energy harvesting requirements by jointly optimising the waveformers at the transmitter and the power splitters at the receivers. A low-complexity fractional-programming (FP) based alternating algorithm is proposed to solve these non-convex optimisation problems. The non-convex wireless energy transfer (WET) constraints are transformed to be convex with a modified quadratic transform (MQT) method. As a result, the stationary points for both the fair-throughput and the sum-throughput maximisation problems are obtained. The numerical results demonstrate the advantage of our proposed algorithm over a minimummean-square-error (MMSE) scheme, a zero-forcing (ZF) scheme and a time-reversal (TR) scheme. Simulation results show that the wireless data transfer (WDT) performance of our scheme outperforms the single-input-single-output orthogonal-frequencydivision-multiple-access (SISO-OFDMA) when the output direct current (DC) power requirement is high. When we have a practical individual subcarrier power constraint, the WDT performance of our scheme outperforms multiple-input-singleoutput orthogonal-frequency-division-multiplex-access (MISO-OFDMA).

“…On the other hand, the two-stage second harvester achieved a peak PCE of 28.7% under the same input power level and frequency while delivering 1.05 mW output power. A. Riaz et al (2021) proposed a single-cell triband rectifier with a multiband impedance matching network that operates at 24, 28, and 38 GHz [122]. A voltage doubler topology is adopted for the rectifier as illustrated in Fig.…”

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.
