hi you guys,
im having a bit of a problem, i got a patch antenna design (2.4GHz), and i want to know the effects of placing Emfit ( polypropilane and aluminion on top of the polypropylane) on top of the patch covering 1/2 along the resonant dimencion (L) .
i know that polypropilane its a dielectric with a low permitivity (1.2-1.3), and aluminium is a conductor so in theory my electric field on one part of the radiation edge is gonna be absobrb, but the other part is gonna radiate just the same, this would have an effect on the radiation pattern,i guess its gonna be half of what it was, so i tried to run a simulation on HFSS, and the radiation pattern its the same so it dosnt meke sense to me, but when i plot magnitude of E field over the aluminium face it shows that its absorbing the electric field, so basically i dont know whats going on
Layer thikness(Polypropilane) 0.07mm
LayerThickness(aluminium)=150nm ( i assumed that it didnt have no thicksnes)
Boundary condition on aluminium = lossy conductor
this is the HFSS File plz help me
