Amateur to HFSS v9.2, need help

Hii guys,

I've started to use this HFSS v9.2 software for my grad project on microstrip patch antenna design, but I don't know where I'm going wrong because I have designed my antenna for 10GHz, but its resonating at 12 GHz, all my calculation and my designing is correct (as far as I think) coz I followed the help manual available along with the software, I'm not able to get hold of the problem, if anyone can help me out, I would appreciate it.

Hi Mirriyaz,
Have you checked your port impedance? There is a port only solve option available with the waveport that helps you to see what impedance you are looking at from the port.
What return loss do you get at 12 GHz? It could be a matching problem as well.
If you could provide more details, it'd be easier to probably see where the problem is.
Hope this helps,
Ananth.

If you post your project file here, I will try it.

Hi..
What kind of microstrip antenna is this? Square, rect, circular or what?
Plus how do u feed it? It would be easier if you post it so I have a look on it.
