The new antenna can handle 5G signal in several ways, each with its own advantages and disadvantages.
The highest speeds are provided by the millimeter wave (mmWave): it allows you to transfer several gigabits per second. This means that it has a high potential for generating electrical energy.
Harvesting millimeter-wave energy has been possible for some time, according to the researchers, but in many cases it was impractical because collecting energy over long distances usually requires large rectifying antennas, you have to keep the rectenna pointed directly at the wave energy source. to make them work.
A Georgia Institute of Technology development solves this problem by using a component called the Rothman lens, which has a spiked shape.
So the antenna was reduced to the size of a human palm, and also made it flat and flexible. Rothman lenses are already widely used in 5G beamforming systems, allowing for expanded network coverage.
