Reply To: 180 Degree Phase Shift When Measuring S21

[David Prestaux]

the jump is very likely due to the integration being swapped so the 180deg jump. in the classic way, you would visualize the vectors. be sure the integration is working well at a few angles . the more certain way in you scenario is using mesh assembly. an example being shipped with the install under the antenna is doing mesh assembly with horn feed and dish antenna . the second step is to keep the mesh for all variations in the parametric sweep ( last tab). it would much easier for you to be under the latest release and also share the design in the classic support I would think.
