Dipole modelisation with HFSS 9
I'm looking for a simple way for modelising electric dipole on HFSS 9. I tried several ones with a "lumped port", but the results were not very good after looking at the far-field radiation pattern... And the time spent for solving by the software was maximum!
Do you know any tips giving good results?
Notice that:
my problem doesn't limit to this excitation, because I need to put the dipole source inside a four-port metallic cavity: the memory needed is huge!! The better solution would be the simplest one... Which doesn't need too many ressources... If it exists! :?
Does anyone understand the excitation "Voltage source" or "Current source" ?? I just don't know what the software is doing with it. I tried to use it for the dipole, but... What on earth does it physically represent in reality
Thanks for your help.
Ok, I ask this question in a different way:
Does anyone know how to make a simple electric and/or magnetic dipole (in simple vacuum), and which gives good results when looking at the radiation pattern?
Thanks.
Here you two simple hfss dipole examples, rad. pat is ok.
One is the some old An$oft example, other to check voltage source is mine.
Post your problematics hfss model if this examples aren't enought, it's the best way to explain what's wrong.
I asked a Ansoft representant for this, and he didn't gave me a good way to modelise it! Perhaps I had to ask someone else...
Anyway, thanks a lot! I was wondering if you had an example for the magnetic dipole... It would be great!
Magnetics dipole can be modeled with aperture, you can excite aperature with plane wave or with source like on picture below.
Now you can do it with yourself :)
