HFSS: Wave port simulation of dipole antenna

Hi,
I want to simulate a dipole antenna in HFSS with a wave port simulation. I want to figure out the change in input impedance of antenna as frequency is changed.

I dont think using a lumped port lets me get this information. I dont want to use a CPW to interface with the antenna because then I will not know what the input impedance of the antenna is.

Is there any way of using waveports to excite the antenna directly.

Yes, there is. You must bend the two dipoles at the center of the structure to connect both metal dipoles to a waveport rectangle. In this case you'll have to deembed the bending-region out of your data.

Just use the lumped port.

Cool. Thanks for the reply. I got it to work with lumped port.

Thanks
