Hi, do you know why this S11 seems wrong at very low frequency, it increases from -15 to 0 in the band from 0 to 0.5 GHz,
it would be still at 0 in this band like this picture ( I refer it in a paper).
I use CST to simulate and the mode at port is Quasi-Tem, I use CPW-fed in my design, E at port is ok,
but impedance is 62 ohm, not 50 ohm like in that paper. Port dimenson is 4W*4h.
Thank you!
