HFSS simulation clarification

  I was simulating a patch antenna for resonant frequency of 2.5GHz and my S11 has a peak at 2.55Ghz, how do I get it to 2.50Ghz?
  
  I am uploading my project. I figured adjusting the length of the patch will do the trick but I have tried and I lose more -dBs when I do that. Any help? Thanks

  Hi,
  The antenna resonance frequency depends on many parameters such as the length & width of the patch, the height of the substrate, etc.
  
  You can optimize the design by using Optimetrics in the project manager window.
  
  Right-click on Optometrics >> Add parametric then add parameters and Analyze.
  
  Please refer HFSS help document for more information.
