Well, i manage to create a probe fed microstrip antenna in momentum. The design is as follows:
Free_Space
----------- Strip Cond
Substrate_1 via pcvia1
----------- Slot hole
Substrate_2 via pcvia1
----------- Strip cond2
Substrate_3
/////////////GND///////////
where
cond is the patch (microstrip layer)
hole is the outer conductor
cond2 is the inner conductor (coaxial cable feeding)
Is this right? Can anybody comment on that??
While the resonant frequency appears to be ok, when i plot the currents i see that they are not on the patch (specifically in the edges) but they flow in the hole layer (which i defined it as a slot i.e. non conductive)
I am really stuck and i don't know what to do.
I would appreciate any help
