Many of today’s vehicles tend to include a wide variety of antennas for AM and FM radio, television, GPS navigation, GMS communication, and automated tolling. A big challenge is to find a solution for the combination of antenna topologies and locations that is both functional and aesthetically pleasing. Integrating antennas into windscreens has become a popular solution. However, designing these windscreen antennas is an extremely complex process that requires the analysis of electromagnetic interactions between thinly layered dielectrics. This white paper discusses how FEKO can provide accurate and efficient solutions in the analysis of integrated windscreen antennas.
