Area/Stream: Engineering, Authors: Kapil Bhatt, Sandeep Kumar, Pramod Kumar, Chandra Charu Tripath Keywords: Dual-band , rectenna, RF–DC conversion efficiency, Schottky diode, sickle-shaped antennaJournal Name: IEEE Antennas and Wireless Propagation Letters Year:2018, Month:, Volume: 18, Issue: 12 Page No: 2637-2641, ISSN: 1548-5757, DOI/Link: https://ieeexplore.ieee.org/abstract/document/8865293Abstract:
In this letter, highly efficient dual-band rectenna at 2.4 and 5.8 GHz for energy harvesting is presented. A new sickle-shaped antenna is designed to operate at both frequencies. Rectenna shows the maximum RF-DC conversion efficiency of 63% and 54.8% at 2.4 and 5.8 GHz, respectively. The impact of matching network and output filter on RF-DC conversion efficiency at both frequencies is analyzed. The output dc voltage of 3 and 2.6 V is measured for 2.4 and 5.8 GHz correspondingly at a 600 Ω load resistance. The rectenna can be utilized for various low-power applications.
