 Distance between connection and ground area on the top layer should at least be as large as the
dielectric thickness.
 Routing the RF close to digital sections of the system board should be avoided.
 To reduce signal reflections, sharp angles in the routing of the micro strip line should be avoided.
Chamfers or fillets are preferred for rectangular routing; 45-degree routing is preferred over
Manhattan style 90-degree routing.

 Routing of the RF-connection underneath the module should be avoided.
 Use as many vias as possible to connect the ground planes.
