2.9 Note in terms of designing 1. Please dont 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 dont place any GND and line to the upper/lower side of the antenna. 4. If you can, please dont 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 dont use metal for cover of this evaluation board.
