Abstract
In this paper, a compact dual-band rectenna operating in the frequency range of 4.8-5.2 GHz (Wi-Fi) and 7.77.9 GHz has been proposed. The antenna dual-band is achieved at a feed length of 38 mm by varying the feed length. The dual-band rectifier is designed with the help of Villard voltage doubler circuit with single T-matching network. The proposed rectenna has been implemented by integrating the rectifier to the antenna. The simulation results of antenna, rectifier, and rectenna are performed individually. The antenna is fabricated, various parameters measured, and compared with the simulated results. The maximum measured power conversion efficiency (PCE) of rectifier and rectenna of 51.7 % and 48.5% have been obtained. © 2019 IEEE.
