I've downloaded and used Smithchart for Excell v2.1 and it does plot Real S11 and Imag S11. The older version of VNA that I am using actually saves the denormalized impedance values R & X when the Smith chart is displayed.

Since I am doing antenna work I am using the one port Smith chart display.

What are the equations for converting the denormalized X & J values to the Real S11 and Imag S11 that are required for the chart?

I've tried different calculations but have not gotten it correct yet.

Thanks
Paul

Hi Paul,

There is a RF calculator in Agilent AppCAD may figure it out. You can download it from Agilent website and it is a free software.
