UHF RECTENNA USING A BOWTIE ANTENNA [PDF]
Progress In Electromagnetics Research C, 2012 In this paper, a rectifying antenna (rectenna) for energy scavenging applications is presented. The proposed device uses a modifled bowtie antenna to collect the electromagnetic energy coming from UHF RFID systems, and RF Schottky diodes to convert it into DC power.

Vortex rectenna powered by environmental fluctuations [PDF]
Nature Communications, 2018 AbstractA rectenna, standing for a rectifying antenna, is an apparatus which generates d.c. electricity from electric fluctuations. It is expected to realize wireless power transmission as well as energy harvesting from environmental radio waves. To realize such rectification, devices that are made up of internal atomic asymmetry such as an asymmetric ...

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.

Design of a Rectenna Array Without a Matching Network
IEEE Access, 2020 A novel approach to designing rectenna systems by eliminating the use of a matching network between the antenna and the rectifier is presented. The proposed rectenna consists of a wide impedance bandwidth 8 octagon disks placed at two different layers ...

High gain isotropic rectenna [PDF]
2017 IEEE Wireless Power Transfer Conference (WPTC), 2017 This paper introduces an original strategy to step up the capacity of ambient RF energy harvesters. The low rectification efficiency that comes from weak input power is enhanced through high gain antenna arrays that push the circuit to operate in a more efficient state.
