Plot Denormalized R & X in Smithchart for Excel - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

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.
