In the US, the FCC regulates the power emissions of antennas. From my understanding, the power limits were set at a time where interference was a huge issue since the communications protocols being used were still nascent. Therefore the FCC restricted the power limits to be low in order to limit...
@IRstuff Their antennas aren't omnidirectional. They're directional patch antennas. So the loss for the reception at a single point using directional power transfer is much lower than the loss associated with omnidirectional transmission.
I'm curious, is this directionality enough to provide...
I came across Energous, a company that claims to be using RF at 5.8GHz to transmit enough power to charge 12 phones from 15ft away.
They have no product on the market yet they still managed to IPO, which sounds like a scam.
It looks like they are using patch antennas to directionally transmit...
