“…Hence, both C j and R s impede the rectifying operation and should be chosen as low as possible. Based on the understanding mentioned above and the Shockley diode model, an analytical model can be derived for rectification efficiency prediction [57], [4]. The current generated by nonlinear junction resistance I diode due to RF input power can be expressed by:…”

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).

Radiofrequency energy harvesting (RF-EH) solutions have evolved significantly in recent years due to the ubiquity of electromagnetic waves in any environment. This review presents a comprehensive report on autonomous wireless sensor (WS) design considerations based on RF-EH. The obtainability of RF-EH-WS is driven by development efforts in the areas of RF-EH circuit design, known as rectifying antenna (Rectenna), the minimization of the energy budget of WS (MEB-WS), and finally, power management modules (PMM). The PMM aims to optimize the energy efficiency of the WS. In addition to these three factors, examining the RF power levels harvested related to the rectenna feeding technique (RFT) is essential. Since we did not find any review presenting a holistic view of these design considerations, we strived to provide a detailed picture of recent advances and new enhancements in this review. To address this issue, this review gives an overview of the seminal and contemporary studies in the RF-EH-WS field. The IoT issues are also discussed in terms of their basic requirement to support reduced size or miniaturized smart objects, which are common matters in current applications of WS nodes. Potential open issues that might be considered for future research are also discussed in this article. For a more detailed description of all presented concepts, many significant references are provided for the readers.

“…If it still consumes conventional energy, that would have a serious impact on the economic and social development of many countries [1]. Due to this problem, many researchers have developed new forms of renewable energy, such as solar energy [2], biomass energy [3], wind energy [4], thermal energy [5], and radio frequency energy (RF), such as the digital TV, mobile, and WiFi frequency range [6][7][8][9][10][11][12][13][14][15]. Due to the foregoing, researchers have been interested in developing the field of energy harvesting from radio frequency (RF) that uses a receiver antenna and AC to DC power conversion circuit.…”

This article presents a dipole antenna using an I-shape adding technique on both sides of the antenna's body to widen the frequency range, using a horn waveguide to gain enhancement and harvest energy by matching the circuit which is compatible with the voltage multiplier circuit at the RF frequency (510-790 MHz) in a TV digital system. Having measured the effect of the antenna, it was found that the antenna operates at a frequency range of 60.24% (450-838 MHz), a 67.79% increase from the base dipole antenna, which has again enhancement of 10.23 dB from adding the horn waveguide (60.99%). It has a pattern of energy radiating in a specific direction, and when the antenna is used with an energy harvesting circuit to get energy or power from the front direction of the TV digital antenna at a distance of 10 km, it is capable of harvesting energy of up to 7.33 µW.
