Gap waveguide technology adopted in next generation automotive radar

Associate Professor Ashraf Uz Zaman and Professor Jian Yang from E2 Antenna group have been performing pioneering research on a new low-loss waveguide technology, known as gap waveguide technology, over the last few years. This technology was invented by late Professor Per-Simon Kildal in 2008. After some fundamental research at Chalmers, in 2011, the company Gapwaves AB was founded to take Gap waveguide-based research results towards industry application. As two of the co-founders, Ashraf and Jian are continuing a strong research collaboration with the company and working towards commercialisation of this groundbreaking technology.

The result of this research at Chalmers is now being commercialised and Gapwaves AB has signed an agreement with one of the world’s largest automotive radar manufacturer company in Germany named Hella.

— This means, Hella will use gap waveguide-based antenna in their future generation automotive radar products to improve their radar sensor performance at 77GHz. The new generation of radars will be produced from 2024 to support advanced automated driving functions, says Ashraf Uz Zaman, Associate Professor at the Department of Electrical Engineering.

— It is great that Gapwaves has reached a commercial milestone. Over the last few years, we have been working in collaboration with Chalmers on many projects and look forward to continuing this collaboration, say’s Lars-Inge Sjöqvist CEO at Gapwaves AB.
