wave port è¨å®š
Hi, buddies:
I got a problem with port setting on Coplanar striplines on ground. Please find details in attached file.
Thanks a lot for your attention!
Hello, everybody:
I remember if there is impedance mismatching at port, then ripples appear on s plots. It might be a common thing.
Welcome comments from others!
hfss waveport integration line
Hi, buddies: I have solved the problems stated above.
Answer for Question1: Try to make a bigger waveport. Remember that there is less risk to make a larger waveport than to make a smaller or narrower waveport, because a smaller port might introduce higher order...
zpv impedance
Hi, buddies and experts:
I got a little problem with explanation of characteristic impedance results from HFSS. Please see the figure. My doubt is why there is a abrupt changing with the impedance curve. Here I took the option of impedance of Zpv instead of other two, Zpi or...
Hi, maybe I can answer your question.
Please take a look at the definition of characteristic impedance: Z=sqrt((jwL+R)/(jwC+G)). W (radian frequency) goes to zero if frequency f goes to zero, which means Z=sqrt(R/G) in this case. In most cases, G tends to be zero, which makes Z infitely large...
Hi, buddies:
How are you?
I got a problem about the port setting of a coplanar waveguide. See the attached file. I did not add any port over here since I have no idea how to set it. The impedance is supposed to be around 50 ohm. But I never got it, please take a look and add proper...
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...
Hi, guys, I have problems with ploting electric field in a set of contours. I tried field calculator to solve this, but the strange thing is that there is a Iso function in v9.0 field calculator, while no such isosurface funtion in v11 counterpart.
Could you please tell me how to draw a set of...
Hello, guys:
I would like to say thanks all of you, specially to Ivan_ and toonafishy. I have solved the problem with the help of Ivan_. And I think toonafishy's suggestions are also correct. Now I think the conclusions to reduce the memory required include:
1. Use the symmetrical plane...
how to choose size of pml in hfss
Dear toonafishy：
Firstly thanks for your warmly help. I got a different result. It runs 40 minutes, and 165858 tetrahetra and then end with out of memory. You can refer to the profile I exported from HFSS. The passes and convergence plot is availbe as well...
hfss 11.1.1

Hello, guys:
I got some problems in my hfss simulation. My case is a very thin film antenna, around 1um in thickness. I know the large ratio of length/width to thickness is bad for meshing and...
Hello, guys:
I got some problems in my hfss simulation. My case is a very thin film antenna, around 1um in thickness. I know the large ratio of length/width to thickness is bad for meshing and simulation, but I have to. Every run ends with errors as followed. Now I attach my project here...
Re: Please help me decide hfss cpw-fed antenna simulation re
:D Thanks everybody! I forgot to assign a material to the monopole, so now it has been solved.
Dear friends:
I have done a simulation on cpw-fed antenna. The project is attached below, and the result have come out. But I am not sure that the resultant is right or not. Please experts check it for me. In this project, is the resonant frequency 2.86GHz(Fig.1), and is the impedance at...
