Figure 46: Reference Design for Bluetooth Antenna
There are some suggestions for component placement and RF trace layout for Bluetooth RF traces:
 Antenna matching circuit should be closed to the antenna;
 The impedance of RF trace should be controlled as 50Ω;
 The RF traces should be kept far away from the high frequency signals and strong disturbing source.
