I am working on designing the 2.4GHz rectangular patch antenna. How to get the resonant frequency at 2.4GHz. I've been getting 2.43GHz most of the time with return loss of -42dB. Which parameter do I need to adjust/look into? I've tried adjusting both width and length of the patch but still could not get 2.4GHz. Any other parametric should be considered? I use Wp=37.7mm and Lp=28.4mm on FR4. Please kindly advise.
