HJWAVE ( CEO Tae -Hwan Yoo ), a millimeter wave (mmWAVE, 30~300GHz) specialist , announced on the 9th that it has released two types of antennas dedicated to imaging radar .
This product uses 4 chips in a cascading structure to implement Tx16*Rx16, 256. The first method , the PCB Phase Array structure, added the EBG (Electromagnetic Band Gap) structure to eliminate the existing shortcomings of channel -to- channel deviation and ripple . The second WGIM (Waveguide Injection Molded) 3D antenna structure is an advanced technique that consists of a total of 3 layers and improves channel -to -channel deviation by 40% and ripple by 20% compared to the improved PCB Phase Array method .
“We maintain an accuracy of over 95% when comparing the simulation results during the development stage with the performance measurement results of the actually manufactured product" said HJWAVE CEO Yoo Tae - hwan . Based on this accuracy, we can reduce the development period and development costs .
In addition, he stated, “ The measurement data of the sample made of aluminum in the prototype stage and the sample with plating applied to the injection molding of the mass production version showed a high consistency of 98.2% . ” and “ By securing this high consistency, we have completed verification of the reliability, stability , and feasibility of technology development . ”
An official from HJWAVE said , “ We are currently conducting projects with two global Chip Markers and three autonomous driving radar companies for this product , ” and “We are currently building a first- stage automated antenna mass production line with an annual capacity of 2 million units at the Yongin plant , and we plan to begin prototype production in October of this year and operate a full- scale mass production line in December . We plan to expand to 8 million units per year in the second stage next year , and we are also considering building an assembly line for finished radar products in the mobility field .
