A question about the isolation of a 40db coupler.Help!!!!~

These days I'm trying on a 40db coupler and the isolation is respected to be greater than 25db,while by using HFSS9.0 I got only 20db.How to improve the fact?
I used a stripline coupler,a very simple model.you can see from the photo.
Hope someone nice can help me ~~please.
Another,how to perform the mesh operation?I mean in a model some part for example the area around the stripline I want the mesh to be a bit more,and other part far away the stripline in vacuum to be less.
Thanks!~~~
The photo of the model is under below

The result of the model above.
No matter how to optimize,the isolation is only 20db
problem solved
thanks
