5G can now wirelessly cost your cellphone utilizing the brand new antenna know-how. When are you able to anticipate it?

Georgia Tech researchers recently found an exciting new way to take advantage of 5G signals that goes beyond simply improving download speed. University engineers have found a way to use the energy in 5G signals and convert them into a miniaturized power source via antennas. With this power supply, phones can be charged wirelessly without affecting your 5G data.

What are these 5G antennas?

On Sunday April 4, the researchers developed a much smaller antenna system while harvesting enough power from 5G calls for massive antennas, according to Bgr.

Georgia Tech engineers also worked successfully to ensure that previous antenna designs could only get power directly from 5G when they were next to the base station. To solve the problem of only looking from one direction, they installed a system with a wide angle of coverage, said Aline Eid, a senior researcher.

To drive this innovation further, senior lab consultant Jimmy Hester noted, “We can run a higher frequency antenna that can receive power from any direction. It’s directional, which makes it much more practical.”

The data from the Georgia Tech research team showed that the new antenna technology resulted in 21 times more energy recovery than previous designs.

The electricity generated by the researcher’s device is expected to be used to power portable devices and IoT-based devices.

Once the 5G presence has spread, researchers believe this technology will enable on-demand battery power over the air.

How do the antennas work?

An article in Nature dated January 12, 2021 explains how the antennas can collect electricity.

They claim that 5G is optimized for ultra-high speed, low latency communication. The FCC chose mm-wave frequencies and allowed unprecedented high data rates.

5G inadvertently created a wireless power grid that can power devices in areas far beyond the capabilities of existing technologies. However, this potential is only possible if a fundamental compromise is removed.

In the present study, the authors propose a paradigm that avoids the usual compromise between angle coverage and switch-on sensitivity.

The concept involves the use of a Rotman lens between the antennas and rectifiers. The flexibly printed mmwave lens enables robust and rigid operation over gain bandwidths of up to around 20 GHz.

The antenna sub-arrays, rectifiers and DC combiners are then added to the structure to demonstrate their effectiveness for coverage and turn-on sensitivity in both flat and curved planes.

The power harvesting capability exceeded 180 m in the current configuration using state-of-the-art rectifiers – the power harvesting capability of 3.6 kW at 180 m with 75 dBm EIRP.

In short, with a few changes in the design of the antenna, you can start creating energy that can power phones. While there is no discussion of how long the phone will take to charge, it is good to know that this technology can be applied to existing technologies.
