Yonsei University (President Seo Seung-hwan) announced that the "5G/6G ultra-wideband millimeter wave lens antenna technology" jointly studied by Professor Chae Chan-byung of the Department of IT Convergence Engineering and Sensor View was published in the IEEE Wireless Communications journal.


The IEEE Radio Communication Journal is considered the top journal in academia, along with Nature (top 0.7%), Science (top 2.1%), and Cell (top 0.5%), which are representative journals in the field of science. The journal is even more meaningful because it is in the top 0.9% of the journal citaion reports published by Clarivate Analytics in the U.S., and the approval rate for publication is extremely low at about 5%.


Millimeter waves are one of the core transmission bands of 5G and are an essential area for high-speed data transmission. In order to preoccupy this technology, the joint research team of Yonsei University-SENSORVIEW Co., Ltd. has analyzed key prior technologies and carried out technology advancement work since 2015.


This study was designed to reduce the "beam squint" phenomenon that occurs in ultra-wideband millimeter wave systems. A beam split is a phenomenon in which the direction of beam steering is reversed at frequencies other than the center frequency, and a lot of beam split phenomena occur in ultra-wideband millimeter waves.


The joint research team developed a new ultra-wideband lens antenna technology by comparing and analyzing the advantages and disadvantages of phase shifter-based arrays and radio wave lens-based arrays applied to existing systems. In particular, this study is significant in that it achieved a transmission rate of about 2.8 Gbps in the 28 GHz band through the implementation of a real-world operating system, not just a theoretical proposal.


Although many research groups have made great efforts to solve this problem based on signal processing, performance degradation has been known as an inevitable problem. However, the joint research team has even secured antenna design process source technology to alleviate this and completely solve the beam squint problem with the developed lens-based array antenna.


This technology is applicable to fixed wireless access communication services in the millimeter wave band. In addition, when applied to small cells, it can be used as an in-building antenna solution that requires high-quality services in a specific direction.


Chae Chan-byung, a professor at Yonsei University, said, "The school's independent research was applied to actual commercial technologies to achieve practical industry-academic cooperation."


Kim Byung-nam, CEO of SENSORVIEW Co., Ltd., said, "We will play a leading role in the 6G field through cooperation with Yonsei University."


The joint research team has demonstrated systems developed by IEEE Globecom, Mobile World Congress (MWC), and Consumer Electronics Show (CES), and showed off its technology by winning CES Innovation Awards in two categories (Mobile Device and Smart City) in January 2023. Starting with the results of this study, we will continue to collaborate to commercialize 5G millimeter waves in Korea and preemptively respond to 6G.


Meanwhile, Professor Chae Chan-byung is a member of the Korea Academy of Engineering and an IEEE Fellow, and in 2022, he is actively engaged in research activities with the support of the establishment of a 6G Open Hub Research Center from NI in the United States. SENSORVIEW Co., Ltd. is also a participating organization of 6G Open Hub.
