A 2.45‐GHz frequency‐selective rectenna for wireless energy harvesting

ABSTRACT In this article a novel 2.45‐GHz ISM rectenna is presented. The linearly polarized rectenna uses two square patch antennas matched using a frequency selective surface before a dual diode rectification in series with the load resistance. Measurements showed a broad angle of energy reception and 79% RF‐to‐DC conversion efficiency. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:2508–2512, 2016
