“…The problem comes out from the circumstance that, often, a single rectenna is not sufficient to supply the common device operations: the problem of wideband energy harvesting systems arises, and possible solutions could be represented by a multi-antenna system [12]. In this case, each antenna (operating at different frequencies) could have its own rectifier to harvest separately DC power [13].…”

Abstract-Radio Frequency Energy harvesting is a research topic of increasing interest, related to sustainability, which could become a promising alternative to existing energy resources. The paper will show all the activities addressed to design a wideband system to recover wideband energy from electromagnetic sources present in the environment. The main idea is to develop battery-free wireless sensors able to capture the available energy into the mentioned bandwidth. The final goal is to realize self-powered Wireless Networks based on Ultra Lower Power -ULP sensors minimizing the need of dedicated batteries. This last feature is particularly attractive in different kind of applications, ranging from military to civil cases. A first system prototype is shown and discussed. Conclusion follows.

“…A differential microstrip antenna [6] with improved gain for RF energy harvesting was presented by Arrawatia et al The antenna was designed and fabricated for GSM900 band (890-960 MHz) with a gain of 8.5 dBi and peak efficiency of 65.3%. The same group of researcher also proposed a broad band bent triangular omnidirectional antenna [7] for RF energy harvesting. The antenna has a bandwidth of 850MHz to 1.94GHz with a peak efficiency of 60%.…”

“…1,2 A single rectifying antenna may be used in some application scenarios such as the handheld mobile devices, 3,4 while an array of rectifying antennas is usually needed to enhance the receiving power, especially for the ground-to-ground WPT system. [5][6][7][8] Most of the research in this area focuses on discussions of AC-to-DC conversion efficiency, and the concept of the capture efficiency of the energy receiving adapter is usually ignored. Recently, inspired by the metamaterial absorber (MMA), 9,10 a concept of using MMA resonator as an energy collector for electromagnetic energy harvesting has been proposed.…”

In this paper, we demonstrate the viability of an energy receiving adapter in a 8×8 array form with high power reception efficiency with the resonator of artificial electromagnetic absorber being used as the element. Unlike the conventional reported rectifying antenna resonators, both the size of the element and the separations between the elements are electrically small in our design. The energy collecting process is explained with an equivalent circuit model, and a RF combining network is designed to combine the captured AC power from each element to one main terminal for AC-to-DC conversion. The energy receiving adapter yields a total reception efficiency of 67% (including the wave capture efficiency of 86% and the AC-to-DC conversion efficiency of 78%), which is quite promising for microwave wireless power transmission.
