many thanks .i have result of testing a structure with network analyzer phase of s21 which i get as a touchstone file format from network analyzer is wraped i think, in matlab how i can unwrap it? using unwrap(phase) in matlab is correct ? i think -200 degree is equal to 160 degree but in matlab their sin and cos are different what is wrong here?!
soryy , if i unwrap tested phase and then +360 degree it is correct? i dont change tested phase?
