7. Antenna of BMS002
7.1 Recommended for PWB Antenna design
Around of the PWB Antenna should keep out of metal over 15mm, So that RF have a good performance ,
See Figure 7.2-1
7.2Module Placement Guidelines
For a Bluetooth-enabled product, the antenna placement affects the overall performance of the system. The
antenna requires free space to radiate RF signals and it must not be surrounded by the ground plane. Recommend
that the areas underneath the antenna on the host PWB must not contain copper on top, inner, or bottom layers, as
illustrated in Figure 7.2-1.
A low-impedance ground plane will ensure the best radio performance (best range, lowest noise). The ground
plane can be extended beyond the minimum recommendation, as required for the main PWB EMC noise reduction.
For the best range performance, keep all external metal at least 15 mm away from the on-board PWB trace antenna.
Figure 7.3-1 and Figure 7.3-2 and Figure 7.3-3 illustrate examples of good and poor placement of the
BMS002 module on a host board with GND plane.
