How to build a matching circuit model in HFSS?

I want to design a matching circuit between an antenna and a filter, can HFSS realize this function?
Did anyone ever do this kind of work in HFSS? Please help me with this, thanks a lot!

Another way is to design the antenna such that it has the required input impedance. This way you won't need matching network, which introduces losses and reduces noise figure.

The problem is, how can I make the antenna have the desired input impedance? Or express it in another way, how can I know the input impedance of a designed antenna in the simunilation?

Use a waveport instead of a lumped port.
