Hi all,

        I have used moats on a couple of designs. Basically to "direct" the RF
return currents where you want them to go. Use the same moat on all layer.
You can check the book: 

"EMC and the Printed Circuit Board. Design, Theory, and Layout Made Simple" 
by Mark I. Montrose. 
IEEE press, 
ISBN 0-7803-4703-X.

        Hope this can help,

        Best Regards,
