HJWAVE has launched two types of phase arrays and 3D antennas exclusively for imaging radar
<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...
