Decreasing Mutual Coupling

[am.jay.kay]

Hi,
I am designing a dual feed, square patch antenna for 60 GHz applications.
How can I decrease the mutual coupling between the two waveguide ports?
I am using CST MWS.

Thanks

place grounded areas around your lines. use vias going to ground. it will look like a coplanar waveguide. I am assuming you are using a microstrip topology.
