This research article presents design, simulation and analysis of a novel meanderline microstrip patch rectenna to harvest energy from the 2.4 GHz and 5.0 GHz frequency bands. The research is approached in two stages. In the first stage, a meanderline microstrip patch antenna offering improved bandwidth, radiation characteristics, and impedance matching is considered. The antenna is constructed on an FR4 substrate, with the radiating patch positioned between the substrate and a solid ground plane. A feedline strip is incorporated in the radiating patch to excite the antenna. An impedance-matching network was designed and implemented in the simulation. A multiband rectifier is utilized to convert RF power into usable output DC voltage. HSMS 2850 Schottky diodes are used to further improve efficiency. The performance of the proposed system is evaluated using Keysight Advanced Design System, taking into account metrics like return loss, radiation pattern, output voltage, and power harvesting efficiency.The proposed rectenna achieved a bandwidth of 1.2 GHz, with a gain of 3.56 dBi at 2.40 GHz and 8.06 dBi at 5.02 GHz. The rectenna demonstrated an output voltage of 3.65 V at an input power level of 30 dBm and -2 mV at -5 dBm input power level. A peak conversion efficiency of 83% was obtained for the overall system. The analysis of simulation and experimental results demonstrated an improved performance of the antenna in terms of increased bandwidth and enhanced power harvesting capabilities.

“…The measured results indicated that the rectifier could attain a power conversion efficiency (PCE) of 26% for a −20 dBm input. Likewise, Surajo et al developed a quad-band rectifier for the utilization of RFEH [23]. The DC voltage extracted from ambient RF signals was 0.433 V, with the rectifier achieving a maximum efficiency of 31.7% at 1.82 GHz across the quad-band when subjected to a −20 dBm input.…”

Recently, there has been an increasing fascination for employing radio frequency (RF) energy harvesting techniques to energize various low-power devices by harnessing the ambient RF energy in the surroundings. This work outlines a novel advancement in RF energy harvesting (RFEH) technology, intending to power portable gadgets with minimal operating power demands. A high-gain receiver microstrip patch antenna was designed and tested to capture ambient RF residue, operating at 2450 MHz. Similarly, a two-stage Dickson voltage booster was developed and employed with the RFEH to transform the received RF signals into useful DC voltage signals. Additionally, an LC series circuit was utilized to ensure impedance matching between the antenna and rectifier, facilitating the extraction of maximum power from the developed prototype. The findings indicate that the developed rectifier attained a peak power conversion efficiency (PCE) of 64% when operating at an input power level of 0 dBm. During experimentation, the voltage booster demonstrated its capability to rectify a minimum input AC signal of only 50 mV, yielding a corresponding 180 mV output DC signal. Moreover, the maximum power of 4.60 µW was achieved when subjected to an input AC signal of 1500 mV with a load resistance of 470 kΩ. Finally, the devised RFEH was also tested in an open environment, receiving signals from Wi-Fi modems positioned at varying distances for evaluation.

“…RF energy sources, such as wireless routers and mobile base stations, are widely distributed in the environment and emit electromagnetic waves (RF energy) all the time. RF energy has become a research hotspot in self-powered WSN research due to its long-distance wireless transmission, wide distribution, and resistance to obstruction and environmental influences [6][7][8].…”

This paper presents a compact RF energy harvesting wireless sensor node with the antenna, rectifier, energy management circuits, and load integrated on a single printed circuit board and a total size of 53 mm × 59.77 mm × 4.5 mm. By etching rectangular slots in the radiation patch, the antenna area is reduced by 13.9%. The antenna is tested to have an S11 of −24.9 dB at 2.437 GHz and a maximum gain of 4.8 dBi. The rectifier has a maximum RF-to-DC conversion efficiency of 52.53% at 7 dBm input energy. The proposed WSN can achieve self-powered operation at a distance of 13.4 m from the transmitter source. To enhance the conversion efficiency under different input energy densities, this paper establishes an energy model for two operating modes and proposes an energy-intensity adaptive management algorithm. The experiments demonstrated that the proposed WSN can effectively distinguish between the two operating modes based on input energy intensity and realize efficient energy management.
