I'm new in this forum dedicated to this wonderful software
I'd like to ask questions if you allow(excuse my english!,I try to make efforts)
I work with momentum, and when I simulate such a patch antenna to see the s11 parmetre
in the graph of parameter s11, I want to stand in the marker (-10dB EXACTLY) for example
but I can not, because the marker does not point to the value of an exact way, how to do it

Marker can be set only at calculated points
If you make a frequency sweep, S11 will calculated for every frequency in the sweep list.
The graph is interpolation between the calculated points. To hit exactly the -10dB would be fortune.
At the end the exact -10dB point has no relevance in practice

have fun with RF
