Design Challenges and Opportunities in Car Antenna Systems

Beskrivning

For many years, car antennas simply imply protruding wires on car bodies that are used for receiving broadcast radio signals. In recent years, many more antenna systems are packed into cars to support new applications and services, including GNSS, Wi-Fi, LTE, SDARS, long/mid/short-range radar, etc. These antennas are challenging to design due to a wide variety of design requirements and constraints. To make things worse, industrial designers want antennas to disappear from the car body altogether. In this talk, I will overview the evolution of car antennas and how the design of these antennas become increasingly challenging. I will then introduce some recent innovations in car antenna design to address the challenges in different use cases. As a representative example of an interesting research problem that benefits from an innovative approach, I will detail the systematic design procedure of a Vehicle-to-Everything (V2X) antenna system that can provide the required line-of-sight coverage, despite being a hidden antenna solution. Going higher up in frequency, I will also introduce our recent design of a 79 GHz series-patch array, which is intended for future cars’ multiple-input multiple output (MIMO) radar.
