  HJWAVE, a Physical AI RF specialist, announced that it has been selected for the 2025 “Patent-Driven R&D Strategy Support Program,” organized by the Korean Intellectual Property Office (KIPO) and the Korea Intellectual property STrategy Agency (KISTA). The program provides tailored patent strategies for small and mid-sized enterprises, integrating intellectual property (IP) strategies from the R&D stage to productization and commercialization. Through this support, HJWAVE plans to pursue divisional and continuation applications for its key patents, while also securing entry into major international markets. These efforts are expected to prevent competitor design-arounds and expand the scope of its patent rights. HJWAVE holds core technologies in the mmWave RF field, including 3D waveguide antennas and radar perception sensors, and has secured numerous registered and pending patents both domestically and internationally. In particular, its 3D waveguide antenna has passed t...

  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...

  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...
