HJWAVE Signs Contract With ‘INFINEON’ To Develop Next-Generation Radar For Self-Driving

 

‘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 an excellent opportunity to propose our antenna technology and products to global autonomous driving companies, while also serving as an important stepping stone for global expansion.”

In the future, HJWAVE plans to strengthen its R&D capabilities, expand into various industries, and establish a campus in Pangyo in addition to its headquarters in Songdo, Incheon. They aim to accelerate business growth by expanding their workforce and facilities.

 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,...
