  I am a newbie in HFSS and encountered the problem of being unable to excite. According to the error message, no extra terminals were found after checking. How can I solve this problem?
  Thank you.

  I recommend using wave ports here.
  You can use the HFSS built-in example "WG Combiner" as a reference:
  File -> Open Examples -> HFSS -> RF Microwave -> wg_combiner.aedt
