On March 27, a University-Industry analysis association lead by Pohang University of Science and Technology (POSTECH) and joined by business partners, Dong-Woo Fine Chem, SK Telecom, LG Electronics, Keysight Technologies, and Y. Tech announced the world’s first ‘Antenna-on-Display (AoD)’ know-how. Headed by POSTECH Professor Wonbin Hong’s research group, this was the first multilateral academia-business research cooperation in Korea. The POSTECH analysis association has efficiently accomplished field testing of this know-how on a 28 GHz 5G Android smartphone platform; they anticipate this to accelerate the implementation of original ideas for 5G gadgets soon.
5G is expected to be a minimum of 20X faster than the speed of 4G LTE. Amongst several wireless elements, the antenna is among the most critical differentiators that allow such expertise leap. 5G depends on millimeter-wave frequencies which are at least a series of magnitude higher than existing 4G LTE and Wi-Fi. Hence, the network attenuation at millimeter-wave becomes a lot better, resulting in the need to “gathering of the antennas” to develop a dense electromagnetic beam at particular directions much like how microscopes work. Eventually, this implies 5G wireless gadgets requires many antennae in distinction to a single-digit variety of antennas during the 4G on.
However, within the cellular industry, the shortage of room to mount the 5G antennas inside mobile devices has been the elemental problem. Future smartphones are anticipated to be ergonomically, aesthetically and technically superior-simultaneously. Utilizing standard antenna know-how, more antennas to support 5G implies an undesired trade-off scenario. Naturally, this contradiction has been slowing down the global implementation of 5G cellular devices.
