Integrating antennas in windscreens has become popular due to the enhanced aesthetics and the increased antenna surface area that enables improved reception. However, the design of such antennas is a complex procedure. Antenna systems contain different antennas with mutual coupling, making it very inefficient and time consuming to optimize the FM-, DAB-, RKE- and TV antennas independently. Wanting to make the optimization process of its multi-port antenna more efficient, Daimler turned to Altair for assistance.
