AN1394: BGM220S Antenna Tuning Guide
This application note provides guidelines on how to design PCBs
for BGM220S modules and how to tune the module integrated an-
tenna.
The information provided is supplemental to the design guidelines and recommenda-
tions included in the BGM220S data sheet.
The main purpose of this document is to provide additional design considerations and
best practices for use-cases when exact implementation of the reference design is not
feasible.
KEY FEATURES
• Layout guidelines
•
Antenna tuning guidelines
• Antenna efficiency reference values
