Anthony Grbic, an associate professor of electrical engineering and computer science, and Stephen Forrest, a professor of materials science and engineering and physics, led the development of the dome-shaped antenna. The prototype antenna operates at 1.5GHz on frequency bands used by Wi-Fi as well as cordless and mobile phones.
The researchers claim their antenna is three times more conductive, 70-percent efficient, and ten times smaller than conventional transmitters. The circular antenna is also cheaper and faster to manufacture, using a imprint processing technique.
“It can be used to fabricate antennas that are of a wide variety of sizes, shapes, frequencies, and designs,” Pfeiffer said in . “Basically if you tell me the data rate that is required for a particular application, I can make an antenna that does this while at the same time being as small as possible.”
So the next time you wonder whether companies can make smartphones any thinner, I think you now know that the answer is "yes".
