| Attracting Series A investment… Sales begin in earnest in 2025

An antenna is essential for wireless services. In order to send radio waves, an antenna is needed to receive radio waves. Kreemo is a company specializing in antennas. It was founded in 2016. On the 15th, Kreemo CEO Hong Won-bin said in an interview with The Elec, “Our goal is to become a world-class company specializing in the development of ultra-high frequency antennas and radio frequency (RF) modules,” adding, “Our corporate value has also been recognized, including the recent Series A investment of 8 billion won. “We are receiving it,” he said. CEO Hong is a professor at Pohang University of Science and Technology. He was selected as the youngest fellow in Korea by the Institute of Electrical and Electronics Engineers (IEEE). He has experience as a senior researcher at Samsung Electronics. CEO Hong said, “Antennas have developed over the past 150 years since they first appeared in the 1800s, but there are still many areas where performance can be improved while maintaining convenience, such as various applications and materials,” adding, “Especially with the emergence of 5th generation (5G) mobile communications and satellite communications. “There is a lot of interest in the ultra-high frequency field,” he explained. The higher the frequency, the stronger the propagation of radio waves. To provide proper service, alignment for transmission and reception must be precise. That is why, in the case of mobile communications, base stations must be built more densely. CEO Hong said, “Ultra-high frequencies have been used for special purposes such as national defense and satellites,” and added, “5G is the first example of using ultra-high frequencies in daily life, and the use of ultra-high frequencies will increase in the future, such as with 6th generation (6G) mobile communications.” Kreemo developed the world's first millimeter wave transparent antenna. This is a technology that allows an antenna to be inserted into a display. If applied to a smartphone, the size of the device can be reduced or the battery capacity can be increased. A global mobile phone manufacturer is testing its products. Satellite communication antennas are planning to enter the market starting in 2025. Last April, LG U+ demonstrated a radio wave mirror called 'Reconfigurable Intelligent Surface (RIS)'. It is a repeater that does not require power. It reflects, transmits and absorbs radio waves and sends them in the desired direction. CEO Hong said, “Transparent antennas can be applied to a variety of products, including not only smartphones but also tablets, laptops, augmented reality (AR) devices, and digital signage. RIS is divided into business for individuals (B2C) and business for businesses (B2B). “It will be able to replace wireless LAN (Wi-Fi) routers (APs) and mobile communication repeaters,” he predicted. Based on the technology developed through antennas, we are also developing manufacturing inspection equipment using electromagnetic waves. The development of the world's first antenna means that the equipment to verify it was also created for the first time in the world. This equipment is also being considered for sale. CEO Hong said, “Due to product line readjustments and delays in 5G ultra-high frequency investment, sales this year and next year will be around KRW 1.5 billion to KRW 2.5 billion, which is less than last year.” “The company’s growth will begin in earnest,” he predicted.
