I am giving the Exact Dimensions to my Rectangular patch antenna . But it is not resonating at required Frequency! Need Urgent Help
I am adding my Structure in HFSS!!


The Rar file First contains my design in hfss !!

Plsss Respond Quick any one !

How badly off is the simulated resonant frequency compared to test results?
A few percent difference can be due to Epsilon r and dimension tolerances...

There is no frequency at which s11 is less than -10 dB but estimated result show that at 7.5 GHz it gives -20 dB ! I have clearly given those pictures in my previuos post please find my HFSS design too and Help me plss
 

I can clearly see that in simulation your patch shows an excellent match at around 7.58GHz.
What is your desired frequency?
If it is different then adjust the dimensions of the patch.
 

Did u simulate my structure in HFSS ?? If so in version and what changes did u make ??
But if you are talking about the pic i included in post, it is desired result not what i got ! i got this result
 

According to my quick calculation your patch should resonate at approximately 6.3GHz. If this is what you are getting in HFSS then everything is ok.
Not sure why you expect 7.5GHz..
