PhD Position on Integrated Antenna Concepts for Next Generation Automotive Radar
Automotive radar has made its way into the mass market and is nowadays available for most car types. Also in the future, automotive radar is considered a fast-growing market, as radar systems become a key sensor in the overall automated driving package. Current automotive radars available on the market can be split in three different types: (1) Short Range Radars (SRR), typically 24 GHz units used in blind spot detection type of applications; (2) Medium Range Radars (MRR), typically used in some lower-specification or speed-range front-facing applications; (3) Long Range Radars (LRR), typically 76/77 GHz units used in long-range autonomous cruise control and collision warning/mitigation applications.
The most recent trend among radar solutions is using radar systems to generate high-resolution 3D images that can both locate and identify/classify objects in the field of view. For such an approach, the LRR sensor types are the preferred solution in the market as their short wavelength allows better image resolution. For the same reason, even higher frequencies, around 140 GHz, are going to be targeted for future radar sensors. At those frequencies, the antennas have to be directly integrated with the front-end electronics. While for LRR sensors the antennas are already co-integrated with the electronics in a front-end module, the wavelength at 140 GHz of about 2 mm allows for even closer integration. Here, the antenna can possibly be integrated on the integrated-circuit itself, giving rise to new front-end design approaches, like direct matching between antenna and amplifier.
This PhD project aims at developing new integration strategies for antennas operating at 140 GHz. The project will be executed in close collaboration with a worldwide-leading semiconductor company in the area of automotive sensing. The PhD candidate is expected to work out novel co-design concepts that achieve an optimum trade-off between antenna and amplifier performance. The ideas have to be experimentally verified by prototypes, which requires knowledge in millimetre-wave measurement techniques and insight into process technologies used in the semiconductor industry. Knowledge in the latter area is advantageous but can also be acquired during the project, e.g. in close collaboration with our technology partners.
Applicants should have, or expect to receive, a Master of Science degree in Electrical Engineering with specialization in the area of microwave engineering and antennas. Besides good subject knowledge, emphasis will be on creative thinking, motivation, ability to cooperate, initiative to work independently and personal suitability for research training. Previous experience in using scientific and engineering software packages such as Matlab, CST, ADS, etc. are advantageous.
