hfss waveport phase

Hi all

Is it possible that two modes in excitation waveport have phase difference?

I want to get circular polarization from horn antenna and I use square waveguide but I don't know how can I adjust waveport?

Best regards

When you set up the wave port turn on multiple modes in the solution. You can then excite the modes , adjusting amplitude and phase as you desire using "edit sources". Look at the on-line help for details.
