WGIM Antenna products

By combining HJWAVE's proprietary WGIM antenna design technology, it is possible to develop a wide-angle, wide-band, high-performance next-generation radar that can overcome the physical limitations of existing PCB-type antennas by minimizing propagation loss and securing a wider and more stable detection range.

1. Wide Broadband

The ability to identify and distinguish objects is increased by more than 500% compared to conventional technology, and the number and size of objects can be recognized more accurately, which can be of great help in enhancing the safety of drivers and pedestrians and preventing accidents.

2. Wide Angle

The radar detection angle range has been increased by more than 150%, forming a 180º detection range with no blind spots, enhancing safety in various environments and enabling coverage of the entire area with a smaller number of radars.

3. Beam Tilt

There is no restriction on the radar mounting location, and it covers a left and right angle of 20º to 80º, allowing for more efficient mounting without a radar antenna tilt adjustment bracket.
