The HUBER+SUHNER 3D antenna is the first long-range 3D metallised plastic radar antenna designed for ADAS (Advanced Driver Assistance Systems), offering ultra-low losses for the most accurate object detection whilst meeting automotive standards.

ADAS uses advanced technologies to assist drivers when using a vehicle, thereby improving performance and road-safety. Based on injection moulding, the HUBER+SUHNER 3D waveguide antenna creates an air-filled waveguide to achieve very low insertion loss, and an overwhelmingly higher performance compared to PCB antennas. Its increased size allows the antenna to read objects from over 300 meters away, offering broad bandwidth and excellent signal to noise ratio.

Key features of the 3D antenna include low weight due to metalized plastic components ; manufacturing process accuracy; cost efficiency and scalability due to tool based inline production; low losses of well under 8 to10 dB/meter depending on performance versus cost choice; and broadband performance , for example, full coverage of 76 to 81 GHz.

With major Original Equipment Manufacturers requesting sensors containing 3D antenna components for heightened performance, HUBER+SUHNER is leading the way in this space as the only supplier to offer 3D antennas for long-range use cases. HUBER+SUHNER develops antennas for all automotive radars, in addition to long-range radar, it also includes mid-, short-range radar and corner radar.

Francesco Merli, Head of Product Management and Development Antennas and mm-Wave at HUBER+SUHNER, said: “The use of waveguide antennas has become an attractive alternative to classical PCB technology. It offers improved efficiency, pattern stability and impedance bandwidth at competitive manufacturing cost. Additionally, exploiting a third dimension facilitates to distribute arrays quite freely over a large antenna aperture allowing to obtain high angular resolution and increased virtual array possibilities.”
