Hello,

Please try increasing the length of the waveguide and instead of radiation boundary assign the ports to the other end of the waveguides and check.

You can go through the "Waveguide Simulation Using Ansys HFSS" AIC course for more information on how to simulate waveguide using Ansys HFSS.

Thank you,
Chinmay
