Hi,I have a problem with the ADS momentum setup.
This is my layout and substrate:


and I want to do the em-cosimulation in schematic to see the S11 at f=2.14GHz:

There are three different types in frequency plan of the em setup,which are adaptive,linear and single.

But the results of adaptive and linear are quite different:
adaptive:

linear:

single:

The result of single seems matched with the one of linear at f=2.14GHz.
But the result of linear isn't smooth,and has discontinuity.
Does anyone know why can not the results match??
Thanks for reply~
