Researchers have uncovered an innovative way to tap into the over-capacity of 5G networks, turning them into 'a wireless power grid' for powering Internet of Things (IoT) devices. The breakthrough ...

5G has been designed for blazing fast and low-latency communications. To do so, mm-wave frequencies were adopted and allowed unprecedently high radiated power densities by the FCC. Unknowingly, the ...

A Maxwell fisheye lens using parallel plate index grading is presented in this study to develop a passive retrodirective antenna array. As a proof-of-concept a design frequency of 10 GHz was selected ...

How did a Georgia Tech team overcome certain limitations to develop an antenna that harvest energy in the 28-GHz band? The key role played by the Rotman lens in making it all happen. Test results ...
