Figure 23: RF trace should be far away from other high speed signal lines

Avoiding the paroling rout of other system antennas nearly.

There should be some distance from The GND to the inner conductor of the SMA connector. It

is better to keep out all the layers from inner to the outer conductor.

GND pads around the ANT pad should not be hot pad to keep the GND complete.
