I am desiring to place the STM32WB5MMG on a board design that already has a large LoRa Antenna. I am reviewing the datasheet and reading over the design suggestions for placing the module.
In particular, I am trying to implement the design with this guidance:
Where d is 22 mm and c is 27 mm. I am trying to decide between two different design choices.
Option A:
Option B:
In both options I can satisfy the conductive enclosure requirements above, but I prefer option B since it will be easier to route. However I am concerned about placing one Antenna so close to another antenna.
Will my LoRa antenna affect the STM32MMWB5MMG Antenna negatively in the second design?
