Re: need help with HFSS multilayer patch antenna simulation

I've had problems with the multilayer patch resonating at two frequencies (upper patch does not resonate). I bet it has something to do with how i feed it. Could somebody who knows about this help me out? And kindly please tell me how you feed multi-layer patch using coax feed?

Thanks a looooooooooot!
