How to compare smith chart plotted on the same diagram in CST MWS?

Hi, everybody,

I found smith chart file has S11 amplitude/phase on CST software, if I want to compare with simulated/measured smith chart plotted on the same diagram, how shall I do?

Thanks in advance.

Hello cyai,

If I understood correctly, you have a Smith Chart result file in a text format, and a seperate simulation in CST MWS. Your goal is to compare the 2 plots on the same screen ?

1.a. If so, then edit the txt file so that you'll have 2 columns: x-axis values (frequency, i guess), then y-axis values (Normalized S11 right?).

b. Go to "1D results" in CST result tree->"Add new folder"->rename it to something like "Smith Chart comparison...".
Go to Macros->File->Import 1D signal->Browse->choose your file->Add plot.

(You'll see your files's content under the new folder)

c. Copy the second result from the result tree and paste it to your new folder.
d. Now you have them together!

2. If that didn't help you can always export ASCII results and post-process them in MATLAB or similar programs.


Good Luck and Regards,
P.
