Hello, dear fellow engineers.
I need help. Quite recently I've discovered that I do not understand S-parameters at all, and here is how it happened.
I considered 1-port circuit physically realized as a microstrip line with open end, 90-degrees long at a certain frequenfy f0. I was trying to find S11 vs frequency, and anyway I look at it, I get a sine curve. However, this is not correct. The picture that I attached to this post shows what MATLAB thinks about all this. And this is not a sine wave.
I'm obviously having a glitch that I cannot resolve on my own. Please someone explaing to me via an example the right way to calculate S11 for the network that I just described.
Thank you in advance.
