STM32WB55 internal antenna

Hello, I have a question about the internal antenna of the STM32WB55CGU6.

First of all, does it have the internal antenna? And if so, what is the range of it? 

Thanks

Hello @Bond00914 and welcome to the ST Community :smiling_face_with_smiling_eyes:.

the STM32WB55CGU6 is an MCU and does not include an internal antenna. But if you are toking about the evaluation board P-NUCLEO-WB55 that use the STM32WB55CGU6, it includes a PCB Antenna that is used as the default antenna. And a SMA Antenna that need to Connect a 50ohms Instrument or antenna so that we can use it:

For the range, it depends on different external characteristics (TX Power, ...). But we can estimate about Few meters (maybe up to 20m).
