“…mmWave rectenna design can involve multiple design iterations to experimentally characterize the rectifier's impedance and diode parameters [23]. It is also not uncommon to see additional prolonged antenna or rectifier feed-lines [41], [42], modified designs post-fabrication [43], as well as a generally higher discrepancy margin between simulation and measurements [25], [44]. The antenna and rectifier design are commonly treated as separate matters and are reviewed separately in Sections V and VI.…”

The broad spectrum available at millimeter-wave (mmWave) bands has attracted significant interest for a breadth of applications, with 5G communications being the main commercial drive for mmWave networks. Wireless power transmission and harvesting at mmWave bands have attracted significant attention due to the potential for minimizing the harvesting antenna size, allowing for more compact rectennas. For a fixed antenna size, the received power increases with frequency. Nevertheless, several challenges lie in realizing high efficiency antennas and rectifiers at mmWave bands. This paper reviews the recent advances in mmWave rectenna design at a component-and system-level. Low-cost antennas and components for mmWave power harvesting, such as high efficiency scalable rectifiers on polymers and high radiation efficiency antennas on textiles, are reviewed. Both the antenna and rectifier can be realized using low-cost fabrication methods such as additively-manufactured circuits and packages, in addition to digital integrated circuits (ICs) for the rectifiers. Finally, this paper provides an overview of future antenna design challenges and research directions for mmWave power harvesting.

“…There is a need for miniaturized and highprecision power sources as the dimensions of modern semiconductors are scaled down to millimeters (mm) and sub-mm [9,10]. Recently, the RFEH module for extracting RF energy in the mm-wave spectrum have not been established because of the lack of widespread deployment of mm-wave networks [11]. The concept of RFEH and wireless power transfer (WPT) in mm-wave are emerging techniques in wireless power communications [11,12].…”

The concept of RFEH and wireless power transfer (WPT) in mm-wave are emerging techniques in wireless power communications [11,12]. This is attributed to the 1990s breakthrough in the mm-wave power transmission and rapid development in mm-wave 5G architecture [10,11].…”

The RFEH design challenges can be broadly classified into overall radio frequency direct current (RF-to-DC) power conversion efficiency (PCE), form factor, operational bandwidth (BW), and compactness. A detailed overview of the essential components of an RFEH system is presented in this paper. Various design approaches have been proposed for the realization of compact RFEH circuits that contribute immensely to mm-wave rectenna design. Effective mechanisms for configuring the rectenna modules based on the recommended spectrums for the RFEH system were also outlined. This study featured a conceptual viewpoint on design tradeoffs, which were accompanied by profound EH solutions perspectives for wireless power communications. The work covers some challenges attributed to 5G EH in mm-wave rectenna: from a controlled source of communication signals to distributed ambient EH and system level design. Conversely, the primary targets of this work are to: (I) examine a wide range of ambient RF sources and their performance with various antennae and RF-rectifier layouts; (II) propose unique rectenna design techniques suitable for current trends in wireless technology; (III) explore numerous approaches for enhancing the rectenna or RF-rectifier efficiency in a low-power ambient environment; and (IV) present the findings of a comprehensive review of the exemplary research that has been investigated. These are aimed toward addressing the autonomous system’s energy challenges. Therefore, with the careful management of the reported designs, the rectenna systems described in this study would influence the upcoming advancement of the low-power RFEH module.
