“…The characteristic impedance of the lines is chosen to be the geometric mean of this range, Z 2 = R b/2, and the input impedance Z in,2 ranges from a minimum Z 2 /2, with ratio of maximum to minimum input resistance determined by (7). This technique, with base = λ/4 and with an impedance transformation stage included at the input of the TLRCN, was used in the example design in this work.…”

“…Examples of such high-power wireless power transfer applications include the coupling of a solar-powered satellite (SPS) with microwave transfer to either Earth or other satellites [5]- [7], as a means to provide increased energy to a transfer vehicle in low-earth orbit to augment propulsion [8], and for the wireless powering of low-altitude airborne vehicles including helicopters [9]. Recently, there has been interest in using high-power microwave power transmission to high altitude platforms (HAPs) acting as communications basestations for both powering and station keeping [26]- [29].…”

Abstract-Microwave-to-dc rectification is valuable in many applications including rf energy recovery, dc-dc conversion, and wireless power transfer. In such applications, it is desired for the microwave rectifier system to provide a constant rf input impedance. Consequently, variation in rectifier input impedance over varying incident power levels can hurt system performance. To address this challenge, we introduce multi-way transmissionline resistance compression networks (TLRCNs) for maintaining near-constant input impedance in rf-to-dc rectifier systems. A development of TLRCNs is presented, along with their application to rf-to-dc conversion and wireless power transfer. We derive analytical expressions for the behavior of TLRCNs, and describe two design methodologies applicable to both single and multi-stage implementations. A 2.45-GHz 4-way TLRCN network is implemented and applied to create a 4-Watt resistancecompressed rectifier system that has narrow-range resistive input characteristics over a 10-dB power range. It is demonstrated to improve the impedance match to mostly-resistive but variable input impedance class-E rectifiers over a 10-dB power range. The resulting TLRCN plus rectifier system has >50% rf-to-dc conversion efficiency over a >10-dB input power range at 2.45 GHz (peak efficiency 70%), and SWR <1.1 over a 7.7-dB range, despite a non-negligible reactive component in the rectifier loads.

“…WPT is a promising technology that has been refocused again, which has attracted so much attention that it is one of the hot spots in recent years for realizing energy harvesting over distances [1][2][3][4][5][6][7][8][9]. Due to the increasing demand for efcient and self-service maintenance equipment and the advantages of being able to reach places where the wired power is inconvenient and impossible to reach, this technology has great potential application values.…”

Resistance compression networks (RCNs) have attracted special attention in the field of wireless power transmission (WPT) since they were put forward. A lot of research work has been done in rectifier basing on RCN for the purpose of increasing conversion efficiency. It is reported that many kinds of rectifiers containing RCN which operate in various circuit and physical forms are proposed. RCN and all kinds of modified versions are studied deeply in this paper, the rectifiers related to which are analyzed also. The results show that RCN only plays the role of bandpass filter (BPF) in the rectifying circuit, which does not reach the original idea of the first proposer. We have different understandings of the rectifying circuits presented in other papers.

In this paper, a new viewpoint on the function of the Schottky barrier diode (SBD) in microwave rectifying circuit is proposed. In the analog circuit field, it has been formed a relatively mature theoretical system about the rectifying circuit, which constitutes the base of subsequent rectifier design schemes. The researchers take it for granted that the SBD selected as the core component in the microwave rectifying circuit should play the role of rectifying in the same way as the diode in the analog circuit. The fact that the one-directional conductivity of the SBD is not observed in microwave circuit by the means of simulation and experiment is proposed. The basis of the former rectification theory is in doubt here. Due to the interaction of the microstrip line and SBD, the DC component generated at the front end of SBD is the key reason for the DC output power of rectifying circuit. The way of DC generation is completely different from the previous idea. Accurate and in-depth understanding of the function of SBD in microwave rectifying circuit will help the researchers to make use of SBD rightly and design circuit in future applications.
