Time Domain conversion of S11-parameter

Hello guys, I am using a Vector Network Analyzer without the Time Domain feature. Otherwise, I am interesting in estimate the impulse time response of my antenna and so I need to implement a Matlab script to elaborate the S parameters. Do you have any suggetions? Or any hits to use ifft?

Thank you all!

i think you can use zero-padding and put the negative frequency data behind the positive frequency data.then use plot(abs(ifft(data))).

Would any one share the code for conversion of S11 ASCII data into time domain representation?

use the timeresp() function in RF toolbox.. But before that take a studyabout why it's used in that way and why there is an extrnal signal given as an argument of timeresp()
