Antenna orientation in nRF52840 DK

[Cmota]

Hi!

I´m currently using the nRF52840 demo board to determine the bluetooth range of the device I'm working on.

The question is: which is the orientation of the antenna on the nRF52840 demo board? 

Thank you very much :)

Not sure I understand the question, do you mean horizontal or vertical orientation? This will depend on how you hold the board.

The antenna is designed on the board. Does it 100% mean that if the board is in the horizontal position, the antenna orientation is also horizontal? I need to be sure about that

Ideally, yes, that would be the case. But in real life, that won't be true as the polarization will change with reflections. So you can't be sure that the signal always have the same polarization.

Thank you so much!! Have a nice day
