Microscale Chiral Rectennas for Energy Harvesting
Advanced MaterialsAbstractWireless radiofrequency rectifiers have the potential to power the billions of “Internet of Things” (IoT) devices currently in use by effectively harnessing ambient electromagnetic radiation. However, the current technology relies on the implementation of rectifiers based on Schottky diodes, which exhibit limited capabilities for high‐frequency

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 ...
