Vehicle to Vehicle Communication

EM simulations have a significant role in automotive industry. One of the most demanding problems is vehicle to vehicle communication, as well as general interaction of the vehicles with the environment. The main applications are toll and safety systems, as well as auto pilot and parking sensors systems. One of the arising frequency bands is 5.9 GHz.

The application note first shows placing 3 short monopole antennas to generic car model. Such simulation is run by MoM on a powerful desktop with two 12-core CPUs and four low-end GPU cards. In the advanced scenario simulation involves two cars. The problem was first analyzed by MoM and then by the DDS solver.

The basic scenario is solve din minutes. The advanced scenario includes 2 vehicles and 6 antennas in total. No symmetry can be applied so total number of unknowns is 364,262. Simulation time in MoM is in hours, while the DDS solver runs the problem in under 30 minutes. The results include antenna radiation patterns, as well as antenna return loss and coupling.
