Radar, vehicle-to-vehicle communication, 5G connectivity, smart road infrastructure and satellite navigation all help ADAS systems be aware of their surroundings, and all these systems heavily rely on antennas and sensors to function.
Placing antennas on vehicles poses several challenges. The body of a car can strongly influence the antenna performance, reducing efficiency and changing the field pattern. Different systems can interfere with each other and other sensitive on-board electronics.
Water and dirt can also soil antennas and sensors, reducing their effectiveness. These factors need to be addressed at the whole system level in order to design safe, reliable ADAS and autonomous driving systems.
Simulation supports antenna and sensor system design and integration by allowing engineers to analyze their performance in real-world scenarios before committing to building a physical prototype. It helps to ensure peak performance and adequate time to market.
