A Circular Polarized Rectenna with Out-of-Band Suppression for Microwave Power Transmission
International Journal of Antennas and Propagation, 2016 A novel circular polarized rectenna with out-of-band suppression is proposed in this paper. The circular polarization is realized by corner perturbation on a rectangular radiation patch and enhanced by a diagonal slim slot etched at the center of the ...

Wireless Power Transfer Using Rectenna
Journal of Physics: Conference Series, 2019 Abstract Radio frequency (RF) harvesting technologies are bewitching a huge number of people as they are enormously available in the atmosphere. These energies are received and converted to useful DC energy which can be used to charge electrical devices which need low power consumption.
