A carbon nanotube optical rectenna [PDF]
Nature Nanotechnology, 2015 An optical rectenna--a device that directly converts free-propagating electromagnetic waves at optical frequencies to direct current--was first proposed over 40 years ago, yet this concept has not been demonstrated experimentally due to fabrication challenges at the nanoscale. Realizing an optical rectenna requires that an antenna be coupled to a diode

Design of a Compact Planar Rectenna for Wireless Power Transfer in the ISM Band
International Journal of Antennas and Propagation, 2014 This paper presents a compact planar rectenna with high conversion efficiency in the ISM band. The proposed rectenna is developed by the decomposing of a planar rectenna topology into two functional parts and then recombining the two parts into a new ...

Textile Rectenna for RF Energy Harvesting [PDF]
2021 15th European Conference on Antennas and Propagation (EuCAP), 2021 Wearable devices are part of many people’s lives, however the batteries they need are a major limitation. In order to solve this problem, an energy harvesting system was studied and implemented, to replace the battery usage and thus enhance the device portability.
