2.9 Note in terms of designing
1. Please don’t place any solid GND and line on below blue line's area. (with the exception of SMT land for this
module.)
2. Because red line's area is the antenna, it should be put on your PCB material.
3. Please don’t place any GND and line to the upper/lower side of the antenna.
4. If you can, please don’t place any metal parts around 15mm from antenna.(indicated by green line's area)
5. Because 2.4GHz is affected of the water, please have distance between the antenna(red line's area) and the
human body as possible as
6. On your system, please don’t use metal for cover of this evaluation board.
