Antenna  guidance 

9.1 Antenna  recommendation 

The  antenna  is  an  important  role  in  the  communication  process. A  good  antenna  can  largely  improve  the 

communication  system. Therefore, we recommend  some antennas for    wireless  modules with excellent  performance  and 
reasonable price.
