    I find these guys to be a little easier to understand in matters of microwave concepts. And I am thinking your question is more specifically directed at characteristic impedance Zo, right?

    One more thing. Agilent has a free software tool you can download called appCad that lets you adjust PCB parameters and calculates the Zo for PCB traces.
