Hi Guys Since all this theoretical garbage is still trailing on I would like to suggest a simple analogy to make it clear. Consider a 50 ohm microstrip on a board terminated in an open Split the line lengthwise with a cut down the center - each side will have approximately 100 ohm impedance if the other side is removed. TDR the two connected together at the source and you will again see 50 ohms. Put a small solder ball at the end connecting the two lines TDR the two again and you will again see 50 ohms. The coupling factor can be igored for this analysis. The idea that you have a circle is foolishness. It is one line split into two forward paths and we know how they act. Now, if you add different loads at different points along the two lines you have a more complex situation but can again analyze it without regard for the circle.
