  • Waveguide antenna technology for autonomous driving radar recognized HJWAVE (CEO TaeHwan YOO), a specialist in millimeter-wave (mmWAVE, 30~300GHz) band RF technology announced that it has been selected for the ‘TOP AUTOMOTIVE SOLUTIONS PROVIDER 2023’ by the global IT magazine CIO Review APAC. CIO Review APAC, a specialized magazine in the field of technology and solutions, has selected HJWAVE, which possesses waveguide radar antenna technology for autonomous driving radar, as a company with innovative and technological capabilities in the Asia-Pacific region. CIO Review APAC explained, “HJWAVE is pioneering the radar antenna market and developing radar antennas using waveguide techniques,” and stated, “Through various research and development projects, it is growing and setting new standards in autonomous vehicle sensor technology.” The antenna for autonomous driving radar, which incorporates HJWAVE’s technology, satisfies both wide-angle and broadband requirements simultaneous...

  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...

  HJWAVE, company specializing in autonomous driving materials, components, and equipment, announced on the 17th that its independently developed autonomous driving radar’s broadband and wide-angle antenna technology has been granted a patent by the United States Patent and Trademark Office. The patent, titled ‘MULTI-LAYER ANTENNA STRUCTURE SUPPORTING WIDE BAND AND WIDE ANGLE,’ enables the implementation of both broadband and wide-angle characteristics simultaneously. It represents an invention that significantly improves the bandwidth by 500% and widens the angle by 150% compared to conventional technologies, while also securing mass production capabilities and achieving an 82% weight reduction. This patent has already been registered domestically and is currently under application with the European Patent Office. Yoo Tae-hwan, the CEO of HJWAVE, stated, “The approval of this US patent validates our company’s distinctive proprietary technology compared to overseas competitors. Fur...

  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 ...
