Hi Annette,

Thank you for reaching out and your patience is much appreciated.

Please note that the Eigenmode solver is not a full solver and it will present all the possible modes based on the model geometry. 

If you want an exact analysis, then use HFSS Modal Network solution type.

Best regards,
Praneeth.
