    How to find characteristic impedance of microstrip with an unknown substrate?

    Nice! It worked like a charm. Now i think i could work with any substrate if i cant know its real permitivity. Thanks!! :)

    How to find characteristic impedance of microstrip with an unknown substrate?

    I may explained wrong. I get the substrate specifications, but is multilayer, so I have differents permitivities for each layer but its behaviour is different all together. I did the momentum simulation of a kind of 50 Ohm / 90º degrees line (based on a medium of all layers permitivities, but...

    How to find characteristic impedance of microstrip with an unknown substrate?

    Hi all, I probably have a simple question. I have to design a circuit with a multilayer substrate which i cannot know his real permitivity nor other parameters but dimensions, I can just use it to my simulations and momentum. But i need to make a 50 Ohms / 90º microstrip line. After doing the...
