“…Such rectennas can achieve a DC output close to or surpassing their counterparts on rigid PCBs as in [74]. However, they cannot be classified as fully low-cost components as they still rely on expensive high-frequency substrates which can be over 90× more expensive than fiberglass or plastics [89].…”

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.

“…The size of the satellite aerial and Earth's rectenna are connected due to diffraction physics. Tests have demonstrated that the concept is theoretically feasible [98] , [99] , [100] , [101] , [102] . Transforming electricity into a form suitable for feeding the grid requires, grid operability techniques such as power conditioning and reactive power control.…”

“…Compared to conventional PCBs, printing eliminates the need for photolithography equipment and photoresistive inks, and is compatible with a wider range of organic substrates. It was previously shown that by fabricating large-area systems on glass and other low-cost substrates, the material cost can reduce by up to 88%, compared to commercial RF laminates such as Rogers "low-cost" antenna-grade laminate [32].…”

Additive manufacturing using direct-write or screen printing represent low-waste methods for fabricating antennas on low-cost flexible substrates. To realize rectennas using low-resolution printing methods, high-impedance antennas with simple printable geometries are required. This article proposes an electrically-small (0.212×0.212λ 2 ) folded dipole antenna design with a scalable impedance for directly matching energy harvesting rectifiers. The antenna is demonstrated in a high-efficiency sub-1 GHz rectenna, with varying mesh fill-factors for optical transparency. The proposed solid (non-transparent) and meshed (70%-transparent) rectennas achieve a Power Conversion Efficiency (PCE) of over 70% and 60% from sub-1 μW/cm 2 power densities, at 940 and 920 MHz, respectively. This represents a 37% improvement in the PCE over state-of-the-art flexible rectennas while maintaining the smallest electrical size and simplest design by not requiring a matching network. The 70%-transparent rectenna's performance is investigated in real-life use-cases showing its suitability for ambient RF energy harvesting with over 500 mV DC output from a phone-call.INDEX TERMS Antennas, dipole antennas, microstrip antennas, printed antennas, rectennas, rectifiers, RF energy harvesting, transparent antennas, wireless power transfer.
