FLC-WFM301 Datasheet
Flaircomm Microelectronics Confidential
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.
Figure 8: Recommended Trace Connects Antenna and the Module
Routing of the RF-connection underneath the module should be avoided.
Use as many vias as possible to connect the ground planes.
