5G antennas beneath the show may enhance mmWave efficiency

Right now, 5G is the hottest thing in mobile technology. According to Cision, a Korean tech company has just developed a technology that is supposed to improve overall mmWave 5G reception. They developed antenna on display.

Antenna on Display is a transparent mmWave antenna that sits directly under the display

With fingerprint scanners under the display and cameras under the display, companies are testing the limits of the technology they can pack right under smartphone screens. Now Dongwoo Fine-Chem has developed a mmWave 5G antenna that sits directly under the display. It will be transparent so as not to interfere with the content being displayed.

Usually the individual antennas are on the back of the phone or near the edges. This is to help them absorb more of the signal. The only problem is the fact that these parts of the phone are usually covered by the hand. Dongwoo said placing the antenna under the display means people are less likely to cover it.

Antenna-on-display technology is still in a very early stage of development. It hasn’t been used on any device, but the company plans to showcase it at MWC later this summer.

What is mmWave 5G and why is it so sought after?

As with any signal technology, there are different bands in 5G. Antenna on Display technology will be able to receive n257, n258 and n260 mmWave bands. Although 5G is faster than 4G LTE, there is a spectrum. At the higher end of this spectrum is mmWave 5G.

The “mm” in mmWave 5G means that the wavelength of the signal is so short that it is in the millimeter range. To achieve this order of magnitude, you need signals with at least 30 GHz. To put this in perspective, typical 5G signals averaged between 2.4 GHz and 4 GHz. mmWave 5G from T-Mobile is expected to deliver speeds between 300 Mbit / s and 1 Gbit / s.

mmWave 5G is the lightning fast 5G that people talk about all the time. It’s also the really spotty and difficult 5G that can fail if you move just a foot away. What it has in terms of speed, it lacks in terms of reliability. mmWave 5G antennas cannot move a signal too far from the source due to the propagation of the signal. For this reason, mmWave signal towers are limited to densely populated city centers.

The carriers have their own names for their own flavors of mmWave 5G. Verizon is called 5G Ultra Wideband. At AT&T it is called 5G + and at T-Mobile it is called 5G Ultra Capacity. The jury is unsure whether Antenna on Display will help users take advantage of the signals from these companies.
