“…Figure 2 illustrates the architecture of the proposed method and Figure 3 shows the circuit topology for a single band of the harvester. One departure from existing work is that this parallel harvester topology is designed to provide a good match to one single-port antenna at multiple bands, whereas most published multiband harvesting topologies make use of multiple antennas, each covering a particular band of interest [9], or make use of dual-band antennas with multiple ports and a single rectifier [10]. Therefore, in contrast to existing work, this system can scale to a large number of frequency bands with no additional antennas or antenna ports required.…”

“…Some work has been done on wideband harvesting [7], tunable harvesting [8], and multiband harvesting [9], [10]. While wideband harvesting can capture energy across a large swath of spectrum, it typically results in very low efficiency at any particular source frequency as the quality of the impedance match between the antenna and single rectifier must reduce as the bandwidth increases [11].…”

Abstract-Harvesting ambient RF power is attractive as a means to operate microelectronics without wires, batteries, or even a dedicated RFID reader. However, most previous ambient RF harvesters have been narrowband, making mobile sensing scenarios infeasible: an RF harvester tuned to work in one city will not generally work in another, as the spectral environments tend to differ. This paper presents a novel approach to multiband harvesting. A single wideband antenna is followed by several narrowband rectifier chains. Each rectifier chain consists of a bandpass filter, a tuned impedance matching network, and a rectifier. The outputs of the rectifiers are combined via a novel diode summation network that enables good performance even when only a subset of the narrowband harvesters is excited. These techniques make ambient RF harvesting feasible for mobile applications. The techniques can potentially enable applications such as ambient RF-powered data logging sensors that upload data to RFID readers when in range.

“…They can operate at singleband [2,3] , dual-band [4][5][6][7], multi-band [8], or broadband [9][10][11]. A narrow band rectenna can give a higher power conversion efficiency (PCE), but the amount of harvested power is low, whereas a multi-band rectenna can has the lower PCE, but more harvested power.…”

This paper presents a novel dual-band rectenna for RF energy harvesting system. This rectenna is created from a dual-band antenna and a dual-band rectifier which operates at GSM bands (900 MHz and 1800 MHz). The printed monopole antenna is miniaturized by two meander-lines. The received signal from the receiving antenna is rectified by a voltage double using Schottky diode SMS-7630. The rectifier is optimized for low input power level of -20dBm using harmonic balance. Prototype is designed and fabricated. The simulation is validated by measurement with power conversion efficiency of 20% and 40.8% (in

“…These kinds of antennas are often designed with a 50 Ω input impedance. Therefore matching networks are used to convert the antenna input impedance to the conjugate of the impedance of the chip Z * chip [1][2][3][4]. However, in case of energy harvesting, this solution is not suitable as it increases bulkiness and losses.…”

Abstract-In this paper, a methodology to design non-50 Ω antennas for energy harvesting is presented. Two prototypes are simulated and realized on an epoxy substrate: one operating at 433 MHz and 900 MHz, the other at 900 MHz and 2.4 GHz. These antennas are designed to match the input impedances of an integrated radio-frequency harvester for an output voltage of 1 V, value chosen considering the voltage needed to power the new generation of micro-controllers and electronic circuits for the Internet of Things. The measurement results indicate a reflection coefficient below −10 dB at the frequencies of interest, validating the methodology.
