hfss microstrip line

2 microstrip lines I simulated in HFSS, one with lumped port and the other with wave port , but I can't get the s11-parameters look like fig.1 . If someone could help to get this characteristic (not necessarily to be exactly the same-it doesn't matter the values of the frequency or dB),I would really appreciate.((s11 : 1Ghz-10Ghz)

Well, Hi :) I'm newbie, and I found this when looking for help in my own creating the microstrip line. Maybe because of earlier version of my program, your files did not work properly. I created my own and found no problems in it. If my file is needed, i can send. :)

Hi miki1234. You must increase the computational domain (the airbox in your case) using, for example, the next values:

position: -35,-35,-20
XSize: 70
YSize: 70
ZSize: 40

(the values were probed in the second example attached in your file)

changing those values the S11 parameter (in your case) don′t pick reflected waves (due to the boundaries) that will affect the response expected.
