So try it at HFSS. And your choice of FR4 is poor in loss tangent and if you dont use suspended structure you may not obtain needed gain.

I was able to get the structure. but can u clear the following points. 1.how should i exite the structure bcoz i will actually put a 2.2pF capacitor for resonating. 2. what should the boundary conditions be. 3.should i model the substrate Thanks
