“…For hardware implementations, research efforts have been made for narrow-band antenna (typically from several to tens of MHz) designs in a single band [73], [108], [114], [115], and dual bands [112], [116]- [118] as well as triple bands [119]- [121]. Moreover, broadband antenna designs (typical on order of 1GHz) have been the focus of some recent work [122]- [129].…”

Radio frequency (RF) energy transfer and harvesting techniques have recently become alternative methods to power the next generation wireless networks. As this emerging technology enables proactive energy replenishment of wireless devices, it is advantageous in supporting applications with quality of service (QoS) requirements. In this paper, we present a comprehensive literature review on the research progresses in wireless networks with RF energy harvesting capability, referred to as RF energy harvesting networks (RF-EHNs). First, we present an overview of the RF-EHNs including system architecture, RF energy harvesting techniques and existing applications. Then, we present the background in circuit design as well as the state-of-the-art circuitry implementations, and review the communication protocols specially designed for RF-EHNs. We also explore various key design issues in the development of RF-EHNs according to the network types, i.e., single-hop networks, multi-antenna networks, relay networks, and cognitive radio networks. Finally, we envision some open research directions.Index Terms-RF energy harvesting, simultaneous wireless information and power transfer (SWIPT), receiver operation policy, beamforming, communication protocols, RF-powered Cognitive radio network.1553-877X (c) 2 transmission. Traditionally, free-space beaming and antennas with large apertures are used to overcome propagation loss for large power transfer. For example, in 1960's, the authors in [15] demonstrate a small helicopter hovering at a height of 50 feet, powered by an RF source with a DC power supply of 270W operating on 2.45GHz on the ground. In [16], the authors demonstrate a space-to-earth power transfer system using gigantic transmit antenna arrays at a satellite and receive antenna arrays at a ground station. For transmit power of 2.7GW, the power transfer efficiency is estimated to be 45% over a transfer distance of 36000km. During the past decade, with the development in RF energy harvesting circuit, low power transfer for powering mobile terminals in wireless communication systems began to attract increasing attention [17], [18]. The authors in [17] propose a network architecture for RF charging stations, overlaying with an uplink cellular network. In [18], a harvest-then-transmit protocol is introduced for power transfer in wireless broadcast system. Moreover, various modern beamforming techniques are employed to improve power transfer efficiency [18]-[20] for mobile applications.It is until recently that the dual use of RF signals for delivering energy as well as for transporting information has been advocated [21], [22]. Simultaneous wireless information and power transfer (SWIPT) [23] is proposed for delivering RF energy, usually in a low power region (e.g., for sensor networks). SWIPT provides the advantage of delivering controllable and efficient on-demand wireless information and energy concurrently, which offers a low-cost option for sustainable operations of wireless systems without hardware modification on the ...

“…Accurate impedance measurement plays a crucial role in RFID antenna designs. Most of the UHF RFID tag antennas use balanced structures [4], this allows to to use just one half of the antenna placed above a conducting grounded plane [4]. In the present case single-ended interface do not allow this avenue.…”

“…In this paper, a printed single-ended antenna with high inductive input impedance over a broad band is presented. It is derived from a differential broad-band antenna recently proposed [4]. The single-ended interface allows to connect it with a highly efficient, low threshold voltage RF-DC circuit proposed in [5].…”

“…One effective solution to mitigate these problems is the set-up shown in Figure 8 (right). Thanks to the antenna symmetry, we just used a half of the antenna placed on a 1mx1m copper ground plane [7]. The antenna was connected to the network analyzer through a coaxial cable placed on the other side of the copper plane.…”

“…A reconfigurable differential RF-DC power converter architecture is selected to improve both conversion efficiency and sensitivity [6]. The converter is combined with a matched broadband PCB antenna [7] to enable the use of the RF energy conversion system at different frequencies in the ISM band. In order to minimize the power losses, no matching networks are used, and the antenna is designed to have an impedance matching the highly capacitive input of the IC converter.…”

In this work, a RF Energy harvester comprised of a differential RF-DC CMOS converter realized in ST130nm CMOS technology and a customized broadband PCB antenna with inductive coupling feeding is presented. Experimental results show that the system can work with different carrier frequencies and thanks to its reconfigurable architecture the proposed converter is able to provide a regulated output voltage of 2 V over a 14 dB of RF input power range. The conversion efficiency of the whole system peaks at 18% under normal outdoor working conditions
