   <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...

  Exclusive Production of Civilian and Autonomous Driving Radar and Antennas HJWAVE Factory Scenery On the 19th, HJWAVE (CEO YOO TaeHwan), a specialist in millimeter wave RF technology, announced that it has completed the construction and commenced operations of a three-story factory spanning 870 pyeong (approximately 2,874 square meters) on the ground and 1,270 pyeong (approximately 4,188 square meters) in total floor space in the Yongin Techno Valley in Gyeonggi Province. This factory holds SQ (Supply Quality) certification, enabling it to produce and supply finished products to Hyundai Motor Company and Kia Corporation, as well as IATF-16949 certification for overseas component supply. Currently, it supplies finished products to domestic and Japanese customers and plans to further establish its identity as a specialist manufacturer of millimeter wave (mmWAVE, 30~300GHz) products by constructing additional production facilities, including radar antenna and assembly lines.
