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's CEO, TaeHwan YOO )   HJWAVE, a specialized RF (Radio Frequency) solutions provider in the millimeter-wave (mmWave) range (30~300GHz), has announced on the 26th that they are launching dedicated antennas for multi-channel imaging radars and setting up dedicated production facilities. These products are designed for a wide range of applications, including autonomous driving imaging radars, perimeter surveillance, and boundary radar systems. They focus on meeting the high-resolution requirements of imaging radars by offering support for multiple channels and improving vertical and horizontal resolutions with an emphasis on reducing Angel Error. Traditionally, radars have supported 12~16 channels, but this product expands support to 144~256 channels. It utilizes a waveguide injection molding antenna technique, which can improve channel-to-channel deviations and radiation patterns by over 60% compared to conventional PCB Phase Array antenna methods. A company representative s...

  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...

  On the 9th, HJWAVE, a specialized company in the millimeter-wave RF field, announced that it has been exclusively selected for a Small and Medium Business Administration’s national project aimed at expanding the market for technological innovation and development. The selected project, titled “Development of Broadband, Wide-Angle Antenna for Reduced Performance Variation between Multiple Channels,” focuses on the technology development applied to autonomous driving image radars and high-resolution, high-definition radars for civilian surveillance. This technology aims to improve variations between multiple antenna channels by optimizing and reducing ripple effects, resulting in more than a 60% reduction in channel variations compared to conventional technologies. Additionally, this technology is expected to be a crucial element for high-resolution radar systems, enhancing the vertical and horizontal resolution, speed, and angle resolution of the radar to detect and differentiate ...

  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...

  RF specialist company HJ Wave Co., Ltd. (CEO Yoo Tae-Hwan) announced on the 4th that it has supplied four types of communication antennas to the smart factory of the world’s top white goods company. The supplied antennas include one type for AGVs (Automatic Guided Vehicles), which are unmanned transport vehicles, and three types for RSUs (Road Side Units) used for communication. The RSU antennas consist of a V2X antenna, an LTE/5G antenna, and a GPS L1&L2 antenna. These products support communication and autonomous logistics and driving between vehicles and road devices through the GNSS system for receiving location information. They also support connectivity to LTE/5G mobile communication networks. The V2X/GPS L1&L2 antenna supports frequencies of 1.2GHz, 1.5GHz, and 5.9GHz, with gains of 9-10dBi and 25-30dBic. The LTE/5G antenna operates in three frequency bands: 824-960MHz, 1710-2690MHz, and 3300-3900MHz, with an antenna gain of 2.5-5dBi. In addition, a communication a...

  Expansion of EMS business area of parts and long secretary in millimeter wave RF field On the 12th, millimeter wave RF specialist company HJWAVE Co., Ltd., (CEO Yoo Tae-hwan) announced that it has relocated its headquarters and research center to the 2nd Pangyo Techno Valley to enhance customer support and human infrastructure. Yoo Tae-hwan, CEO of HJWAVE, stated, “This decision was made to effectively develop technologies through close proximity to and collaboration with customers in areas such as autonomous driving and mobile communication, as well as to strengthen expertise and diversity by actively reinforcing talented personnel.” He further added, “After expanding our business scope from components (60, 77, 79 GHz radar antennas) to equipment (60 GHz, 77 GHz radar EOL testers) following the successful investment attraction of the Free A series, we anticipate achieving results that will shorten the timeframe by more than two years compared to our revenue plan for this year.” ...
