“…For short range operation, a small volume of energy can be harvested from Wi-Fi router transmitting at 50 to 100 mW. Meanwhile, for long range operation, higher gain antennas are required to harvest RF energy from broadcast radio towers and mobile base stations (Pradhan et al, 2014).…”

This research presents architecture of Ultra Low Power (ULP) Micro Energy Harvester (MEH) using Radio Frequency (RF) signal as an input. RF has many advantages compared to other ambient sources because it is not affected by changes of weather or time, does not require heat or wind exposure and it can be moved randomly within the bound of the transmission source. When RF is used as the sole input, the designer needs to consider impedance matching as the most important element so that the antenna can transfer maximum power. The existing energy harvesters apply conjugate matching network as the current solution. However, this method causes some difficulties since the solution requires consideration of both voltage boosting and conjugate matching network simultaneously. To solve this problem, we propose ULP Radio Frequency Micro Energy Harvester (RFMEH) that will utilize a control loop as voltage boosting adjuster and network tuner to achieve maximum power transfer and minimum power reflection. The proposed architecture will also improve the RF-DC conversion efficiency and the sensitivity of the system. This is achieved using an efficient rectification scheme to convert RF to DC, DC-DC boost converter to increase the dc output voltage, adaptive control circuit to adjust the switching timing of boost converter, voltage limiter and regulator to produce the best output voltage. The proposed ULP RFMEH architecture will be designed and simulated using PSPICE software, Verilog coding using Mentor Graphics and functional verification using FPGA board (FPGA) before being implemented in CMOS 0.13 µm process technology. The proposed architecture will deliver approximately 2.45 V of output voltage from low input power level (-20 dBm) with an efficiency of more than 60%. This design will minimize the power consumption as compared to previous achievements and it can be applied in supplying power for health care monitoring systems or micro biomedical applications.

“…When compared to wired connections, wireless power transmission is better since wired connections are inconvenient, hazardous, or could even be impossible [3]. Though the physics of both are related, it is different on purpose of transferring images such as television broadband, where the percentage of the received power is only important if it becomes too low to successfully recover the signal [4]. With wireless energy transfer, efficiency is the most Manuscript received March 5, 2015;revised December 20, 2015.…”

Abstract-The Wireless Power Transfer (WPT) system has enabled numerous applications in clean energy applications since their major goal is to recycle the ambient microwave energy. It is enough to drive low power consumption devices. In such system, microstrip antennas are utilized as the main component for collecting the electromagnetic energy. Antenna design is important in the proposed rectenna. The antenna absorbs the incident microwave power, and the rectifier converts it into a useful electric power. In this paper, we focus on the design of two microstrip antennas with resonant frequency of 1.88GHz and 2.45GHz to utilize in the WPT system for LTE/WLAN low power devices. The maximum return loss for each of microstrip antennas was simulated by MATLAB programming. The conversion efficiency of the fabricated antennas was measured as 38% and 35%. The results of this research can be applied in other mobile technologies.Index Terms-WPT, rectenna, microstrip antenna, LTE/WLAN, low power.

Energy harvesting has been investigated by many researchers due to their ability to generate power by using existing sources which eliminate the need of batteries and power supply that requires extra cost to the system. Rectifier is the main component in energy harvesting where it converts RF sources to DC power. This work presents the design and investigation of the seven-stage rectifier. A Villard configuration is chosen with consists of two HSMS 2850 Schottky diodes and two through hole ceramic capacitors for each stage. The aim of this article is to study and evaluate the rectifier performance at 550 MHz and 900 MHz frequency range. Rectifier properties such as number of stage, capacitance effects, and variation in capacitor's combination, and are analyzed and discussed in this article. The result shows that the designed rectifier is operate well at the targeted frequencies. Measured results show that voltages of 9.17 V and 3.78 V are obtained for an input of 0 dBm at 900 MHz and 550 MHz, respectively. The circuit is generating 44.4% rectified output than in the reference work. V C 2016 Wiley Periodicals, Inc.
