“HJWAVE, Selected for National Project of High-Resolution Radar Antenna”

 


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 small objects. It is anticipated to significantly contribute to the accuracy and reliability enhancement of autonomous driving and surveillance systems.

HJWAVE stated, “We have been highly evaluated for our business feasibility by comprehensively considering our numerous intellectual property rights, ongoing development and production projects related to autonomous driving radars, and collaborations with domestic and international radar manufacturers.” They explained the reasons for their selection in this new national project.

HJWAVE’s CEO, Yoo Tae-Hwan, commented, “The demand for antenna development for high-resolution radars is expected to increase across various fields. Through this government-supported project, we aim to leap forward as a top company in the domestic and international millimeter-wave (30 ~ 300GHz) antenna industry by securing technology and mass production capabilities for high-resolution waveguide antennas.” He further expressed his aspiration, saying, “In the field of waveguide antenna technology, which has high overseas dependency, I want to contribute to improving the trade balance through localization, enhancing the global competitiveness of domestic autonomous driving and civilian radar.”

 Secures 6 Patents for 20 to 80-Degree Beam Tilt Structure Millimeter-wave (mmWAVE) RF specialist HJWAVE (CEO Tae-Hwan Yoo) announced on the 7th that it has launched an antenna with a beam tilt function designed to improve the installation of corner radar used in autonomous vehicles. Corner radar is a type of radar installed at the corners of a vehicle. A representative from HJWAVE stated, "Previously, vehicle radars were categorized based on distance into LRR (Long Range Radar), MRR (Middle Range Radar), and SRR (Short Range Radar). However, with the application of 3D waveguide antenna technology, there is now a trend towards classifying radars based on their installation positions." They explained, "Corner radar is mounted at four corners of the vehicle, enabling it to detect distances over 200 meters and provide 360-degree coverage around the vehicle. Beam tilt technology is essential for corner radar to ensure installation flexibility within the vehicle." The re...

   <PCB Phase Array Type Antenna(Left), Waveguide Type Antenna(Right) > HJWAVE (CEO Tae-Hwan Yoo), a specialized company in millimeter wave (mmWAVE, 30~300GHz) technology, announced on the 9th that it has launched two types of antennas exclusively for imaging radar. The new products utilize a cascading structure with four chips to implement Tx16*Rx16, a total of 256 elements. The first method, a PCB Phase Array structure, incorporates an EBG (Electromagnetic Band Gap) structure to eliminate the channel deviation and ripple that are typical shortcomings of conventional methods. The second method, the WGIM (Waveguide Injection Molded) 3D antenna structure, consists of three layers and improves channel deviation by 40% and ripple by 20% compared to the improved PCB Phase Array method. HJWAVE CEO Tae-Hwan Yoo stated, “Our company maintains over 95% accuracy when comparing simulation results during the development stage with the performance measurements of the actual products...

  < Waveguide Type 24GHz PCB Antenna and Performance Measurement Results > HJWAVE, a millimeter-wave (mmWave, 30~300GHz) RF specialist company led by CEO YOO Tae-Hwan, announced on the 8th that they have launched a 24GHz waveguide antenna implemented on PCB. HJWAVE has introduced a waveguide technology integrated into PCB using Copper and Via, departing from the conventional method of producing waveguide antennas solely through plating on metal or injection molding. A representative from HJWAVE stated, “In smart city-based ITS (Intelligent Transport Systems), collaborative driving between vehicles and traffic control systems is essential, requiring high detection range and wide detection area capabilities of traffic control radar. To achieve this, we have developed PCB antennas incorporating waveguide technology in the 24GHz frequency band, allowing for improvements in detection range, expansion of detection area, size reduction, and cost savings.” HJWAVE’s CEO, YOO Tae-Hwan,...
