Title: what is active S-paramter, and passive S-paramter?
Post by Jack on Oct 24^th, 2009, 8:10am

Dear All,

To measure the antenna performance, there is always the "passive S-paramter" and "active S-paramter".

I try to find them in google, but it seems nobody mention it.

What is the difference in the definition?

Thanks!

Jack

Show me documents or materials where you saw terms of "passive S-paramter" and "active S-paramter".
