Fullwave Simulation and Analysis of Portable Transmitter Immunity Testing
Performing virtual prototyping to understand and solve EMC problems is becoming a norm in a typical product cycle. There are various forms of EMC simulations that can be performed. Of the many types, immunity simulation is one the most beneficial as the results obtained through measurements are difficult and almost impossible to quantify due to potential risks of equipment damage and human safety concerns associated with it.
In this presentation, 3D EM simulation is applied to model and analyze the impact of the field coupling to the DUT. Systematic analysis through gradual inclusion and impact of each individual component, such as the mobile transmitter antenna, PCB, TFT display, and metallic housing will be discussed. Through the use of 2D field plots and 3D field animations, it was possible to focus on the root cause of the problem. Having identified the source, virtual prototyping was applied to improve the robustness of the design.
