Hello Robbin,
The Antenna Designer and PCB Antenna Designer apps display impedance plots, but don’t have a built-in Smith Chart view. However, you can still use Smith Charts with a couple of workarounds:
In Antenna Designer, export the design to a script and use:
imp = impedance(antenna, freq);
smithplot(freq, imp)
This lets you visualize the impedance on a Smith Chart outside the app.
In PCB Antenna Designer, if you can export S-parameters as a Touchstone file, you can use:
s = sparameters('filename.s2p');
smithplot(s)
These steps allow you to view Smith Charts using the RF Toolbox functions
Here is the documentation link for the used functions:
impendance:
smithplot:
sparameters:
Hope this helps!
