“…Fig. 1 presents a survey of rectifier and rectenna efficiencies at 915 MHz [9]- [22]; 2.45 GHz [6], [20]- [36]; 5.8 GHz [35]- [46]; 8-12 GHz [47]- [55]; [24][25][26][27][28][29][30][31][32][33][34][35]- [62]; and 90-95 GHz [62]- [69]. Markers with a black outline are rectifier efficiencies estimated from rectenna measurements, as explained in Section IV-E. Markers with no outline are simply rectifier measurements.…”

This paper presents a large, modular X-band rectenna array developed for the planned demonstration of a space-to-Earth power beaming link operating at 10 GHz. The array is composed of 16 tiles assembled into a panel greater than 1 m × 1 m in size. To accommodate tests during the early development and construction of the space-based transmitter, the rectenna cells are designed to maximize performance at low power densities using commercial-off-the-shelf Schottky diodes. To increase efficiency at the expense of some field-of-view, each rectenna cell employs a 4-antenna subarray to feed a single diode. Array performance is validated over a 30-dB range of power densities from 1 mW/m 2 to 1 W/m 2 , reaching a total rectenna efficiency in excess of 39% at 1 W/m 2. The rectenna array's field of view, defined by the 3-dB beamwidth of its antenna subarray, is 36 • × 36 •. The DC power collected by each tile is combined in a reconfigurable manner to control the output voltage level for the protection of electrical loads. These results are expected to directly influence the first demonstrations of space-to-Earth power transfer. INDEX TERMS Wireless power transmission, rectennas, solar power, satellites. FIGURE 2.

“…Even in studies using a packaged GaAs Schottky diode [17], 100 mW class rectification was not realized at 94 GHz. For a study using another diode [18], a high-power oscillation source gyrotron was used to supply high power to the rectenna and thereby achieve 100 mW class input. Nevertheless, difficulties persist because the rectifier circuit and the antenna cannot be evaluated separately: accurate performance evaluation and design modification are difficult; moreover, the rectification efficiency is as low as 20%.…”

Wireless power transfer (WPT) is one solution to realize long flight times and accommodate various missions of micro-uncrewed aerial vehicles (MAVs). Reducing the constraint of power transmission distance and realizing high beam efficiency are possible because of the high directivity of WPT using millimeter wave (MMW) methods. Nevertheless, no report of the relevant literature describes an investigation of sending power to an MAV using MMW because MMW rectennas have low efficiency. The purpose of our study is to conduct fundamental research of a high-efficiency and high-power rectenna at 94 GHz aimed at MAV application using MMW. As described herein, we developed and evaluated a 100-mW-class single-diode rectifier at 94 GHz with a finline of a waveguide (WG) to a microstrip-line (MSL) transducer. With the optimum load of 150 Ω at input power of 128 mW, the output DC power and rectifying efficiency were obtained respectively as 41.7 mW and 32.5%. By comparison to an earlier study, measurement of 94 GHz rectifiers under high power input becomes more accurate through this study.

“…Output power and output frequency have improved each year [21]. Nevertheless, few earlier studies have used a gyrotron for wireless power supply: Ariel University in Israel has conducted wireless power supply experiments using a gyrotron with 5 kW output at 94 GHz [22]. The University of Tsukuba in Japan has 25 array rectennas using a 28 GHz gyrotron [23], achieving a submillimeter-wave wireless power supply using a 303 GHz gyrotron [24].…”

Research on wireless power transmission by a rectenna using millimeter waves and subterahertz waves is gaining attention. It is expected that energy harvesters at high frequencies will be developed for use with future 5 G. High-power wireless power supply to various applications will be possible because of miniaturization of the rectenna. As described herein, we investigate earlier studies of millimeter-wave wireless power supply, selecting and explaining salient examples of millimeter-wave high power wireless power supply.
