My HFSS simulation is always different than what is in the reference paper.!!!

hi guys, I really need help in HFSS here, I totally wasted my last two weeks of my life trying to fix it, I am doing my master thesis about wifi 6E tri band antenna, I have started by simulating ready design from papers, but always get wrong or not same s11 curves, I have checked all things
1- solution frequency
2-delta s
3-solution type
.
.etc

If any one have time and Idea to help me do that I can send you y designs and papers try help me how to get same results...

thanks

Hi,

I can't help with HFSS.
But when you say "but always get wrong or not same s11 curves".. what does this exactly mean?
A deviation below 1%, or 100%?

The better you tell us what you expect (values with units, waveform, diagram...) and what you get instead (values...) the better the members can find out what's causing the deviation ... and better can say how to rectify it.

From my experience as an EM simulation expert, designs from published papers often have some small mistake/typo or missing information and often can't be reproduced in simulation. It seems that some authors don't want to share complete design information...

On top of all missing or wrong information, most of the antenna papers are focalized only on S11 and VSWR performances. I think less than 20% of them (I don't exagerate with this number) mention something about measured radiation and efficiency performances, when actually these are the most important charateristics of an antenna.
