Wireless power transmission was conceptualized nearly a century ago. Certain achievements made to date have made power harvesting a reality, capable of providing alternative sources of energy. This review provides a summ ary of radio frequency (RF) power harvesting technologies in order to serve as a guide for the design of RF energy harvesting units. Since energy harvesting circuits are designed to operate with relatively small voltages and currents, they rely on state-of-the-art electrical technology for obtaining high efficiency. Thus, comprehensive analysis and discussions of various designs and their tradeoffs are included. Finally, recent applications of RF power harvesting are outlined.

Abstract-A mathematical model of a large rectenna array (LRA) is presented. It is shown that matrices describing the LRA linear subsystem have a number of specific features that must be considered when the rectenna mathematical model is developed. The state equation for the LRA was obtained. It is shown that the model functioning in nonlinear mode of the infinite rectenna array can be reduced to the parameters of one equivalent receiver-rectifier element (RRE) at the fundamental frequency and its harmonic. The external parameters of RREs and characteristics of LRAs were obtained.

“…After the parameters of the via‐hole are determined in Section , the proposed via‐hole structure is adopted in the subsequent design of multilayer rectifying circuit. Usually, the rectifying circuits are composed of DC blocking capacitor, input filter, rectifying diode, and output filter . The microwave passes through the input filter and on to the Schottky diode where the microwave energy is rectified to DC energy.…”

This article proposes a novel concept for constructing a microwave (MW) rectifying circuit by using a multilayer structure, aiming at reducing physical dimensions. Specifically, an embedded via‐hole with connection of conductor layers in the multilayer structure is designed. A full‐wave electromagnetic analysis is carried out to study the impacts of various via‐hole design parameters. Then, a C‐band rectifying circuit based on HSMS‐286C Schottky diode is fabricated with the proposed multilayer structure for demonstration. The maximum MW‐DC conversion efficiency of 61% has been measured. In comparison with the counterpart, namely a conventional microstrip rectifying circuit, the proposed multilayer circuit shows a great reduction of physical dimensions and a very similar efficiency, which validates that the proposed circuit can reduce physical dimensions significantly without sacrificing the MW‐DC conversion efficiency.
