With the rising expectation for autonomous and self-driving vehicles, we expect a considerable increase in the number of communication, wireless and sensing systems in an automotive platform. These systems are required to provide different levels of connectivity including network, data, and vehicle to vehicle connectivity. For sensing systems, another level of integration and communication among the network of sensors including cameras, radars, RFID detectors, etc. are required to accommodate the possibility of combining and processing the information obtained from these sensors in real time. The increased demands for these and many more additional services and applications that are now becoming an integral part of vehicles result in a more stringent requirement on integration of additional antennas, cameras and sensors within a platform that is densely populated already, thereby leading to a stricter condition on size, range, isolation, interference and electromagnetic compatibility.

In this presentation, the antenna solution for three important applications are discussed. These applications include: 1- MIMO antennas for 4G LET wireless cellular data connectivity; 2- Dedicated Short Range Communication (DSRC) antenna systems; and 3- Integration of rear view cameras with the roof antenna.

For the cellular data connectivity, a MIMO antenna consisting of two (a primary and a secondary) antennas is presented that covers all the cellular frequency bands. We need at least two antennas with a reasonably low correlation and the spatial and polarization diversity that are required to meet the 4G LTE speed and throughput. To identify the best placement of the two cell antennas a drive test near cell towers in an urban area is needed to obtain an understanding of a real life performance.

DSRC antennas are the next topic discussed in the presentation with numerous potential applications in safety, collision avoidance, traffic control and management, toll and parking payment and smart drive. The DSRC antenna consists of a two-element array which are combined and connected to the Electronic Control Unit and provide the necessary information.

Finally, we discuss about the latest effort in integrating the camera into the antenna platform that already consists of a large number of antenna platforms including DSRC, 4G LET MIMO, satellite radio and GPS antenna. The main goal is to characterize the adverse impact of the blockage and interference introduced by the camera and mitigate them to the extent that the integrated camera antenna demonstrates a similar performance to the one without the camera blockage.
