HJWAVE (CEO Tae-Hwan Yoo), a specialized autonomous driving millimeter wave (mmWave, 30–300 GHz) RF company, announced on the 1st that it has released a 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 centered on technology that can tilt the beam from 20 to 80 degrees to remove constraints that occur when mounting radar on a vehicle to enhance performance to support fully autonomous driving, and non-contact transition technology that minimizes loss due to the gap that occurs when combining RF MMIC and antenna. 

In addition, in line with the SDV (Software Defined Vehicle) trend of automobiles, cost reduction was achieved through technology in the antenna (component) section to secure price competitiveness of radar, and a module unit business model combining RF MMIC and antenna is in progress.

 HJWAVE CEO Yoo Tae-hwan said, “For fully autonomous driving, antenna technology that can be applied to DF-type RF MMICs is emerging as an essential technology due to issues with performance, price, and manufacturing in radar. Also, since the use of Phase Array Antenna, which was applied to the existing IF (Indirect Feeding) type MMIC, has become impossible, we expect an explosive increase in demand for DWnT antennas based on our waveguide injection molding original technology.” He added, “We are currently working closely with two of the top three RF MMIC companies in the world to apply our DWnT antennas, and the project is in progress through a contract with one of them. In addition, we expect to see various achievements, including additional contracts, in the second half of this year.”

In addition, he stated, “We are currently working on securing a quality system and manufacturing infrastructure that meets the requirements for supplying to automobiles through ongoing investment, and we will complete this within this year.” He added, “We are currently securing antenna technologies such as integrated radome and integrated PCB, which are future technologies desired by the market and customers, in various millimeter wave frequency bands (60 GHz, 77 GHz, 79 GHz), and we are also in the process of securing technology for 140 GHz radar antennas that will be used in the future era of autonomous driving. Starting in 2024, when we complete securing patents and mass production capabilities, we plan to additionally build strategic cooperative relationships with various domestic and foreign SIs, and through this, we will rise as the No. 1 autonomous driving millimeter wave RF company in the Asia Pacific region.”
