integration line port hfss
Hello, buddies:
Happy new year!!
I got some confusions on integration line assignment in a wave port. Please see the attached file. For File 1, I would like to obtain the port impedance of the folded dipole antenna, leading to the choice of a wave port which can facilitate solving a characteristic impedance. My aim is to solve the port impedance at 2.45GHz, so I tried to solve port only setup. When I connected two midpoints of two arms as the endpoints of an integration line, the port impedance varied much, let's say, from about 187 ohm to about 208 ohm, compared with the case without assignating an integration line. The problems are 1, Should I assign an integration line for a wave port? 2, What integration line are correct one for this case?
For File 2, I have no confidence about the settingup of the excitation assignment. I measured the impedance of this coplanar stripline(CPS) that is about 24 ohm(whatever from TDR or VNA measurement), but now from this simulation it appears about 85.5 ohm. So No.1, what's wrong with this? 2, Is the setting correct?
Thanks for your time!
