This is a prototype of a new “3D” antenna made by printing a new nano material onto a curved surface. It’s supposed to give up to 3 times better signal than the majority of mainstream antennas. And the one’s that made it are some researchers at the university of illinois. Now what i have to ask, isn’t this so obvious that it just should’ve been made a lot earlier. Printing thin metal “snakes” on the inside of a device’s chassis.
