7 RF Layout Guidelines 
FMB100 integrates an on-board Meander line antenna to radiate and receive the RF signals. The antenna 
has been well designed and tuned for common usage but  it still needs to have good ground clearance 
around the antenna to get good RF performance. 
1. No ground below antenna region (copper cut out in Figure 4) of the FMB100.
2. There  should  also have a  good  ground  panel and  clearance  on the main  PCB  board on  which  t
he
module is mounted. As shown in Figure 5.
