( 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.

  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...
