Electromagnetic simulation is becoming an increasingly vital part of the automotive design process as vehicle electronics become more complex and development cycles shorten. Many new technologies such as automotive radar, intervehicle communication systems and on-board computers are developed using simulation from the beginning of the design process. Tasks that were traditionally done by experimentation, such as electromagnetic compatibility (EMC) and electromagnetic interference (EMI) analysis, antenna placement and cable harness layout, can be made more efficient by using simulation to create “virtual prototypes”.
CST MICROWAVE STUDIO® (CST MWS) is applied to the simulation of electrically large automotive structures, demonstrating the comprehensive CAD facilities offered by CST MWS to both import and modify structures. An on-glass antenna example demonstrates...
Electrical Fast Transient/Burst (EFT/B) Susceptibility of an LV Circuit Breaker
The coupled voltage at component level has been simulated using CST MICROWAVE STUDIO SUITE® for two PCB releases of the same Low Voltage Circuit Breaker (LV-CB) electronic control scheme. The results show a good agreement with actual measurements.
MIMO Systems Simulations for Automotive Environment
Multiple Input Multiple Output (MIMO) systems are often used to improve the quality of service and efficiency of wireless communications. The automotive environment is an especially challenging problem for antenna systems, since the large metal chassis...
A Square Loop Antenna Using Hybrid High Impedance Surface and Four Way Wilkinson Power Divider
A planar square loop antenna on a hybrid High Impedance Surface (HIS) is simulated, including a four way Wilkinson power divider. Using a hybrid HIS means the overall profile of the antenna can be reduced. The semi doughnut radiation pattern produced...
