I have a flex board with 4 traces. 2 traces on top and 2 traces on bottom that go directly over each other. no reference plane. It is almost like a broadside differential and differential pair together, so basically there is a quad pack of traces. how to a calculate the impedance for that. what calculations can i do and then how to modify for this situation.
