   <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...

  Millimeter-wave Pencil Beam Antenna achieving a 7GHz bandwidth (57~64GHz), a beam width of 6 degrees, and a gain of 33dBi <60GHz Pencil Beam Antenna released by HJWAVE> Millimeter-wave (mmWAVE, 30~300GHz) specialist HJWAVE (CEO Tae-Hwan Yoo) announced on the 19th that it has launched a ‘Pencil Beam Antenna’ with a beam width of within 6 degrees (horizontal & vertical) at a frequency of 60GHz. This product features a waveguide slot array composed of 256 element devices arranged in three layers, providing a wide bandwidth of 7GHz from 57GHz to 64GHz. It has a gain of 33dBi and a size of 7.5×7.5cm. Additionally, four slots are implemented in a 2×2 sub-array configuration, with these sub-arrays arranged in vertical and horizontal directions with 8 units each, resulting in a 16×16 configuration of 256 slot arrays. This design allows the antenna to operate with a beam width of 6 degrees in both vertical and horizontal directions, functioning as a Pencil Beam Antenna. An HJWAV...
