It is based on two different monitored architectures using switch circuits controlled by the input powers. One architecture is more adapted to high input powers and the other to low input powers. The two different architectures and the system are designed and realized on Teflon glass substrate with a relative permittivity of 2.1 and thickness of 0.67 mm. They are tested separately as a function of the distance from the relay antenna. A new multiband antenna with a size of 40 \u00d7 30 mm2 is used for both architectures and the system. The measured antenna gains are 2.7 dB, 2.9 dB, and 2.55 dB for the frequencies of 1.8 GHz, 2.1 GHz, and 2.66 GHz corresponding to the mobile communication networks, respectively. The rectifier consists of two Schottky diodes forming a full-wave rectifier and voltage doubler. The maximum measured RF-to-DC conversion efficiency is 71.5%. The proposed RF-EH system provides a maximum DC output voltage of 5.6 V and 3.15 V for an open and 2 k\u2126 resistance load, respectively.<\/jats:p>","DOI":"10.3390\/s22093576","type":"journal-article","created":{"date-parts":[[2022,5,8]],"date-time":"2022-05-08T23:27:25Z","timestamp":1652052445000},"page":"3576","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["A New RF Energy Harvesting System Based on Two Architectures to Enhance the DC Output Voltage for WSN Feeding"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9293-5211","authenticated-orcid":false,"given":"Chemseddine","family":"Benkalfate","sequence":"first","affiliation":[{"name":"Quartz Laboratory, Department of Electrical and Electronic Engineering, Ecole Nationale Sup\u00e9rieure de l\u2019Electronique et de ses Applications, 95014 Cergy, France"},{"name":"STIC Laboratory, Department of Telecommunications, Faculty of Technology, University Abou Bekr Belkaid, Tlemcen BP 230-13000, Algeria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Achour","family":"Ouslimani","sequence":"additional","affiliation":[{"name":"Quartz Laboratory, Department of Electrical and Electronic Engineering, Ecole Nationale Sup\u00e9rieure de l\u2019Electronique et de ses Applications, 95014 Cergy, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abed-Elhak","family":"Kasbari","sequence":"additional","affiliation":[{"name":"Quartz Laboratory, Department of Electrical and Electronic Engineering, Ecole Nationale Sup\u00e9rieure de l\u2019Electronique et de ses Applications, 95014 Cergy, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohammed","family":"Feham","sequence":"additional","affiliation":[{"name":"STIC Laboratory, Department of Telecommunications, Faculty of Technology, University Abou Bekr Belkaid, Tlemcen BP 230-13000, Algeria"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Zhang, M., Liu, X., Guo, H., Yang, X., and Xie, D.
