Hi,
according to the savvasha_prj the feeding point is not in it right place, I attached the project that I worked on, check paperomni_via_momentum where I moved the feeding point to the required point as mentioned in the paper. and also I used the via in the momentum, by attaching the vias...
Hi,
The substrate is correct.
the feeding point is not correct !! not similar to the paper.
Sorry I was busy.
I will try to simulate it, if time allows soon.
Added after 2 hours 9 minutes:
Hi,
I believe that the inaccuracy in the simulation is due to the fact that the substrate(Comclad)...
hi,
1- sorry the configuration you are mention it is not correct, you need to remove the ground, select it and chose open boundary. and there is no need for the Free space layers.
2- the via is correct for the short option in one condition it should be between the two layers metal you are...
hi,
I will try to help you, according to what you listed you need to know what parameter in the list needs to be changed, In order to give a correct dipole antenna.
I recall the code that you are currently using is a tutorial I have seen but can not find at the moment. according to...
Re: Need Help Fixing this Board.. (weirdest thing I've seen
Hi,
Truly amazing problem, am interested what frequency that you are working at ?
Did you considered that your design is marginally stable, did you do any simulation for it? normally in the feedback circuits of OP-AMP...
dear,
please check the feeder of the antenna in the paper that you are mentioned, this may cause the problem. if possible upload the antenna paper that you are referring to.

hi,
I had a quick look on your file. I think the problem in the defining of the PML boundary's, there should be a radiation or FSS reference boundary.
I will check it further if I had the time. hoping this give you a hint to start investigating.
hoping that you will find a...
hi,
"Can you make the file compatible with HFSS 9.1?" sorry I have no idea if this is doable, but there is no thing in the help of the HFSS.
"An importatnt percent of incoming power reflects back ", according to result the s11 is -15 dB at the 2.45 GHz, there is a very little reflectd power...
Hi,
if this is an antenna there are two things missing in the model, first is the rad BC that is required to analyze an antenna.
the second thing is to define a far field pattern.
after doing these things there is a radiation pattern in the far field please check it. but the pattern is...
Hi,
I do not think it is a coordinate system problem, please check what are your settings for the infinite sphere in the radiation section(check phi, theta values), leave the default of change them to span all the area phi (0 to 360) and theta from (0 to 180), I believe that you set theta from 0...
Re: HFSS 9.2 S Parameter
Dear Pedro,
what is your design frequency of the patch antenna. what is your reference of the design there is a resonance at about 4 GHz.
there are notes about the setting like the Rad is not lambda/4 distance from the antenna surface, and the ground slug is not an...
