In modern devices WPT becomes more and more relevant. There are different use cases for a WPT connection. On one hand users want to have a very easy way to charge a mobile device e.g. a smartphone. And on the other hand mobile devices for very rough environments need to be sealed and have no opportunity to get a wired charging connection. In all this cases a simulation model is very useful for a designer and gives him a lot of advantages in the design stage. Therefor we derive a wideband simulation model for a wireless power transfer coil link.
