  Exclusive Production of Civilian and Autonomous Driving Radar and Antennas HJWAVE Factory Scenery On the 19th, HJWAVE (CEO YOO TaeHwan), a specialist in millimeter wave RF technology, announced that it has completed the construction and commenced operations of a three-story factory spanning 870 pyeong (approximately 2,874 square meters) on the ground and 1,270 pyeong (approximately 4,188 square meters) in total floor space in the Yongin Techno Valley in Gyeonggi Province. This factory holds SQ (Supply Quality) certification, enabling it to produce and supply finished products to Hyundai Motor Company and Kia Corporation, as well as IATF-16949 certification for overseas component supply. Currently, it supplies finished products to domestic and Japanese customers and plans to further establish its identity as a specialist manufacturer of millimeter wave (mmWAVE, 30~300GHz) products by constructing additional production facilities, including radar antenna and assembly lines. CEO YOO...

  HJWave, a specialized RF company in the field of autonomous driving millimeter-wave (mmWave, 30~300GHz), announced on September 1st that they have launched the DWnT antenna solution applicable to the RF MMIC DF (Direct Feeding) coupling method that supports autonomous driving. The DWnT (Double Wide and Tilt) antenna is focused on enhancing performance for full autonomous driving by eliminating constraints that arise when mounting radar on vehicles. It features the ability to perform beam tilt from 20 to 80 degrees, which is essential for full autonomous driving, and minimizes losses in the gap that occurs when RF MMIC is combined with the antenna through a non-contact transition technology. Furthermore, in line with the trend of Software Defined Vehicles (SDVs) in cars, to secure the price competitiveness of radar, cost reduction through technology has been achieved at the antenna (component) level, and a business model for modules that combine RF MMIC and antennas is being pursu...

  Autonomous driving component company HJWAVE Co., Ltd., (CEO Yoo Tae-hwan) announced on the 10th that it has signed a contract to supply vertical radar inspection equipment (EOL, End of Line) for performance calibration testing of MRR (Middle Range Radar) radar to a domestic autonomous driving radar company. The newly developed vertical radar EOL equipment has been downsized to 78% compared to the conventional horizontal radar EOL, and the price has been reduced by 40%. The focus was on providing customers with advantages in terms of efficiency in production line space and price while achieving the same performance as the conventional horizontal type. HJWAVE has already completed the supply of 50% of the contracted quantity, and the remaining supply will be completed in the third quarter of 2023. In addition to the supply of EOL for LRR (Long Range Radar) and SRR (Short Range Radar) that have been supplied in the past, HJWAVE will now supply EOL equipment for all types of radar fo...

  ‘HJWAVE Co., Ltd. (CEO Yoo Tae-hwan)’ announced on the 13th that they have signed a contract related to the development of next-generation radars for autonomous driving, combining their proprietary core technology, WGIM (Wave Guided Injection Molded) antenna technology, with the new autonomous driving radar chipset from the global semiconductor company ‘Infineon.’ The WGIM antenna technology is a crucial component technology for autonomous driving radars, determining the size and performance of the radar. It satisfies increased detection range and wide bandwidth/wide-angle characteristics based on low loss, about 10% compared to conventional antenna technologies. Additionally, it has the advantages of compactness, beam tilting capability, and modular platform configuration, allowing the release of new radar products by simply changing the antenna module. Yoo Tae-hwan, the CEO of HJWAVE, stated, “Through the development of next-generation radars with Infineon, we consider this as ...

  HJWAVE Co., Ltd., a specialized RF company in millimeter-wave (mmWave) technology ranging from 30GHz to 300GHz, announced on the 14th that they have launched a WGIM antenna supporting a 5GHz bandwidth in the 79GHz band, which can be used in various mobility applications. The company plans to initially apply this product to autonomous vehicle forward and rear sensing, side detection, and imaging radar. They are currently engaged in joint development with domestic Tier1 radar manufacturers and global chipset companies in the field of autonomous driving radars. The WGIM (Wave Guided Injection Molded) antenna technology, supporting a 5GHz bandwidth in the 79GHz band, can achieve wide bandwidth and wide-angle characteristics simultaneously, compared to conventional antenna technologies. Moreover, it overcomes the drawbacks of previous waveguide antennas such as price and weight issues, by enabling platformization through separate antenna module configuration and eliminating the use of...

HJWAVE Co., Ltd. Participates in “Infineon OktoberTech 2021 Automotive Radar” On October 21, 2021, HJWAVE participated in Infineon’s “OktoberTech 2021 Automotive Radar” event, targeting global customers and consumers. During the event, Infineon and HJWAVE demonstrated two jointly developed products, the High Performance Radar (Cascading MMIC) and the Compact Radar (Waveguide Antenna), in the “High Resolution Radar (77GHz Radar)” section of Automotive ADAS Radar. HJWAVE applied two antenna solutions for these products. The High Performance Radar (Cascading MMIC) utilized PCB Array Antenna technology, while the Compact Radar (Waveguide Antenna) employed the proprietary WGIM (Waveguide Injection Molded) antenna technology. In particular, the Waveguide Injection Molded antenna, which applies a technique of plating metal onto plastic, offers not only size and weight reduction but also cost-saving effects. Based on its unique and superior performance compared to similar overseas technologies...
