 |  Georgia tech creates 5G harvester Can power devices Georgia Institute of Technology boffins have developed a small, 3D-printed rectifying antenna that can harvest electromagnetic energy from 5G signals and use it to power devices. According to a university press release, the move is a way of turning 5G networks into "a wireless power grid”. According to the journal Scientific Reports, the flexible Rotman lens-based rectifying antenna, in other words, rectenna, the system can perform millimetre-wave harvesting in the 28-GHz band. The Rotman lens is commonly used in radar surveillance systems to see multiple directions without moving the antenna system, especially for beamforming networks. However, larger antennas, which unfortunately have a narrowing field of view, are needed to harvest enough power to supply devices, limiting usage. The researchers solved this problem by using a system that has a wide-angle of coverage. The Rotman lens provides six levels of view simultaneously in a pattern shaped like a spider. https://fudzilla.com/news/mobile/526...s-5g-harvester |
