 Proves Radar Antenna Technology for Autonomous Vehicles, Accelerates Global Market Expansion HJWAVE, a millimeter-wave (mmWave) RF specialist led by CEO Taehwan Yoo, announced on the 11th that its 3D waveguide antenna for autonomous vehicles has successfully passed the internationally recognized IEC60068-2 reliability test. The test, conducted by an accredited testing institution, confirmed the product’s ability to meet demanding environmental conditions, comparable to those required for automotive safety components. The product underwent rigorous environmental testing, including 1,000 cycles of thermal shock ranging from -40°C to 125°C, as well as high temperature and humidity, high-temperature storage, and temperature-humidity cycling tests. It also received the highest rating (Level 0) in the peel test. These results demonstrate that the antenna meets quality standards equivalent to complete radar systems used in autonomous vehicles, successfully passing the final stage of reli...

| HJWave's representative interview with Yoo Tae-Hwan HJWave, a company that started as a specialized component manufacturer focused on millimeter-wave (mmWave, 30-300 GHz) RF technology, is now transitioning into a technology firm targeting the ‘Physical AI’ era. The company is focusing on two pillars: core technologies for high-performance cognitive sensors and device manufacturing capabilities. We sat down with CEO Yoo Tae-hwan to discuss the company's vision and strategy. Q: How is HJWave preparing for the Physical AI era, and what role does the 3D waveguide antenna play? In the Physical AI era, HJWave provides 3D waveguide antennas used in high-performance cognitive radar through millimeter-wave RF design. These antennas serve as the ‘eyes’ in the Physical AI environment, playing a crucial role in autonomous driving, robotics, and industrial automation. A 'radar' is a core sensor that functions even in bad weather or at night. Among these, waveguide antennas contri...

  HJWAVE, a company specializing in millimeter-wave (30–300GHz) RF technology, announced that it has registered a U.S. patent for an antenna technology that can be immediately applied to radar systems for autonomous vehicles operating in the millimeter-wave frequency band. The patent, titled "Antenna Structure with Reduced Angle Error," is a core technology that enhances detection accuracy—an essential component of wideband, wide-angle, multi-layer waveguide antenna systems. In automotive radar systems, a multi-channel transmit and receive structure is commonly used. If the radiation patterns of each antenna channel are not uniform, discrepancies in phase and amplitude of the received signals can occur, making it difficult to accurately determine the position of an object. Additionally, signal coupling (interference) between antennas can create ripple effects or signal nulls in the radiation pattern, weakening signals at specific angles. This degrades object detection accurac...
