How to extract mix electrical/EM model for antenna (ANT). The ANT model is base on SnP and FFD Data. Extracting this
model requires Electrical and EM Data coming from Simulation Domain. It takes into account the dispersive effects
present in the antenna band and the mismatch introduce with non_50 Ohms element. The general hypothesis of this model
is concerning the Far Field hypothesis. This model is interesting for modeling the load pull effects in modern
RF front end.
