“…To analyze the PCE of the proposed rectifier, Figure 5a presents the result of the load terminal (R L ) sweep at various input power levels (from −15 dBm to 10 dBm in step of 5 dBm). The result shows that the efficiency increases with an increase of input power across the load which agreed well with Equation (7) [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. The rectifier achieves a maximum PCE along the 2-4 kΩ load terminal in both cases.…”

“…Figure 4b also shows the effect of capacitance (C1) in the MN, varying the capacitance from 2 pF to 10 pF deteriorates the rectifier matching. Hence, lowering or increasing the capacitance value leads to rectifier mismatched which can render the rectifying circuit inefficient [9,20]. To analyze the PCE of the proposed rectifier, Figure 5a presents the result of the load terminal (R L ) sweep at various input power levels (from −15 dBm to 10 dBm in step of 5 dBm).…”

In this paper, a compact rectifier, capable of harvesting ambient radio frequency (RF) power is proposed. The total size of the rectifier is 45.4 mm × 7.8 mm × 1.6 mm, designed on FR-4 substrate using a single-stage voltage multiplier at 900 MHz. GSM/900 is among the favorable RF Energy Harvesting (RFEH) energy sources that span over a wide range with minimal path loss and high input power. The proposed RFEH rectifier achieves measured and simulated RF-to-dc (RF to direct current) power conversion efficiency (PCE) of 43.6% and 44.3% for 0 dBm input power, respectively. Additionally, the rectifier attained 3.1 V DC output voltage across 2 kΩ load terminal for 14 dBm and is capable of sensing low input power at −20 dBm. The work presents a compact rectifier to harvest RF energy at 900 MHz, making it a good candidate for low powered wireless communication systems as compares to the other state of the art rectifier.

The exigency for continuous use of electrical devices has created greater demands for electricity along with more efficient transmission techniques. Energy from natural resources can be solar, thermal, vibration, friction, or Radio Frequencies (RF) signals. This state-of-the-art work provides a summary of RF energy harvesting techniques and can be used as a guide for the manufacture of RF energy scavenging modules. The use of Radio Frequency (RF) Energy Harvesting (EH) technique contributes to the development of autonomous energy devices and sensors. A rectenna system includes three main units: the receiving antenna, the impedance matching network, and the rectifier. We thoroughly analyze how to design a rectenna system with special emphasis given on the design of the rectifier. At the same time many works of the last 10 years are presented. This review article categorizes the used topologies depending on the type of antennas, IMNs, and rectifiers and comparatively presents their advantages and disadvantages.

“…Rectennas, as one of the key devices for harvesting RF energy, have experienced long-term development, and much effort has been made to enhance the overall RF-DC conversion efficiency and output DC power. Considering the above two aims, many rectennas with the characteristics of high efficiency [6,7], broadband [8][9][10], multiband [11][12][13], or multiport [14,15] have been extensively investigated by researchers in recent decades, driving the improvement of wireless energy usage. For example, a high-efficiency rectenna was proposed in Ref.…”

A High-Efficiency and Reconfigurable Rectenna Array for Dynamic Output DC Power Control

et al. 2022

View full text Add to dashboard Cite

In this paper, an output power reconfigurable rectenna array is proposed for the first time to harvest RF energy. The proposed rectenna array can be used to capture abundant RF energy with high conversion efficiency in a wide range of input power levels and load impedance at 1.88, 2.35, 3.5, and 4.9 GHz simultaneously. The output DC power of the proposed rectenna array can be changed exponentially by altering the on-off state of the switches located between the antenna and the rectifier. The measured result shows that the output power is linearly related to the number of opened switches. Therefore, the proposed rectenna array can be flexibly applied to battery-free or low-power-requiring devices according to their different power needs.
