Gapwaves, a Sweden-based company, has announced the release of new waveguide antennas for short-range and mid-range radar, aimed at improving the safety of autonomous driving. The antennas, which are made using Gapwaves' unique gap waveguide technology, are designed to support a range of applications, including adaptive cruise control, blind spot detection, and lane change assist, among others. They offer complete coverage of the automotive frequency bands at 76–81 GHz and 140 GHz, making them suitable for a wide range of radar applications.
The new automotive radar antennas offer a number of benefits over traditional solutions. Using simple riveting to assemble the antennas instead of soldering, screws, or glue, Gapwaves has been able to reduce manufacturing costs while simplifying the design. This has resulted in a thinner, more cost-effective antenna that offers high performance and a wide field of view.
The antennas are also designed to be compatible with a range of different radar sensor designs, including board launchers and launchers-in-package (LiP), with solutions available for major chipset manufacturers. The addition of different layers to the antenna, such as an absorber, enables easier integration into the radar sensor, while a thermal spreader supports the cooling of ICs.
Overall, Gapwaves' new waveguide antennas offer a high-performing, cost-effective solution for automotive radar applications. With their advanced functionalities, robust RF connections, and tailored solutions for low-cost radar sensors, the company is positioning itself as a market leader in the field.
