,but I don't know how to build the model of diode in HFSS?
Could anybody help me ,Thank you very much.

model it with RLC lumped components, regards!

HI Edmund, have you got any example on this subject of diod? I would like it, thanks so much !

to EdmundZheng,
would me please give me a model of diode simulated by hfss?
Thank you very much .

ya man surely u can model a diplein HFSS...
here is a file of dipole in HFSS
have a look into it
