My capacitor is too big, so I didn't notice the troughs in the S11 because it is at a very small frequence,
Now I reduce my cap to pF and I get the S11 at 4.25MHz.
Thank you very much!
Thank you very much for your answer!
This is indeed the case. The S11 curve obtained by the circuit simulation is not normal. If I don't understand it correctly, my capacitor is not the right size. So if you need to build a normal resonant circuit, how much capacitor do I need?
Thank you again...
I want to get the input impedance which look in form port 1 at different frequencies, but I can only get the results that close to zero, I think this is due to the capacitance, but I don't know how to simulate in a right way.
I will be very grateful if you can help me！:-):-)
