“…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.…”

“…Many foregoing types of research in the RFEH system focused on a much higher frequency between GSM/1800 to WLAN/5200 to achieve compactness. The operational frequency contributed significantly to achieving a compact RFEH circuit [7][8][9][10][11][12][13][14][15][16][17][18]. The RF spectral survey from the open literature and the one carried out in this work, using (Aim TTi PSA6005 6 GHz RF spectrum analyzer), come out with a notable result surrounding the lower GSM/900 band towards generating higher available ambient RF power [14,15].…”

“…An RF rectifier is proposed in [15], the design can achieve up to 33% efficiency at −10 dBm input power at the cost of complex circuit with large electrical length. A maximum PCE of 47.8% and 38% is highlighted in [16,17], using an input power between (5-14 dBm), respectively. The authors of [13] also worked on rectifier circuit and realized 50% maximum PCE using 21 dBm solar panel.…”

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.

Abstract-A broadband high-efficiency rectifier with shunt-diode circuit topological structure is presented in this paper. By utilizing the two-level impedance match network, the rectifier can achieve a high microwave-direct current (mw-dc) conversion efficiency within a broad range of operation bandwidth. A stepped microstrip line and a cross-shaped microstrip stub as two-level match network is designed to extend the operation bandwidth. A cross-shaped stub connected to the capacitances act as a dc-pass filter to block the fundamental frequency wave and the high order harmonics and further improve mw-dc efficiency within a broad bandwidth. Experimental results show that the peak conversion efficiency is 80.3% at the frequency of 1.9 GHz when the input power is 22 dBm. When the input power is 19.5 dBm, the bandwidth of efficiency higher than 70% is 40% (1.80 GHz-2.72 GHz). This rectifier has the characteristics of low profile and easy integration, which is suitable for RFIDs, WSNs, and other applications.
