Dear Azita,

I haven't CST at my pc now, but if I can remember correctly, after selecting s-parameter, or any other plot in cst, you could see its phase or magnitude or in dB,just by clicking on some item at plot properties among tabs, existing in upper part of program window. 

I wish you can find that.

hi dear. thank you . i know about plot the phase. but i want unwrap them. in hfss i can do it, but it is difficult in cst software.

Dear Azita,

You should see arg(s) column in Navigation tree for watching the phase of s_parameter and If you want to export it in the txt format you should follow this

1.Go to navigation tree

2. select arg (s)

3.After select arg(s) click on file and you will get a export option

4.And you get Plot ASCII data option.Save this result 

 I hope this is useful information for you

i can unwrap the phase by adding the C letter before the phase in HFSS unit cell. 

and the simulator can unwrap the phase automatically. i want do this in cst simulator without exporting the data.

Hi Azita, you say you can unwrap the phase in HFSS, but you don't give some details, how we can do it ?!!! I need this. Thanks

hi yousef

i attach pictures for unwrapping the phase in both software

Thanks

is clear now!!
