2. The bigger Antenna clearance area, the better. The Antenna itself needs to stay away
from any circuit or component at least 2mm. Antenna clearance area means Top and
Bottom both required to be cleared.
Bottom both required to be cleared.
3. Do not use metal materials on design where near Antenna area. For example, battery
snaps, USB connector, iron case, etc.
4. For RB4000HM-c model (external antenna type), when RF trace meets a turning
point, try to make the RF trace as smooth as you can’t use right angle trace.
These guidelines are for design reference; real performance still depends on actual
design.
