Radicom Research Inc RB4000 사용자 설명서

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. 

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.
