design of coupler ,using Ansoft Designer in EM planar simulation

[arezou]

Hi
I try to simulate a edge coupled line,and broadside coupled line coupler with Ansoft designer, I used this component from librery ,in circuit cimulation I get the good result but when I chang the Cosimulator to EM planar I get the bad result, with this dimention when I used the ADS(momentum-full wave simulation I get the good result),I think I havee some problem in EM planar design.is yher any people to help me

also I dont know is in the page of circuit simulation just changing the Cosimulator to EM planar, the full wave simulation be done or we have to use thepage of EM planar???
thank you
