About the antenna array on nRF 5340 DK

I'm currently working on a class project with nRF 5340 DK about localization. I started with the program Direction finding connectionless locator, trying to get the Angle of Arrival. But I'm considered that although the Direction finding connectionless locator provide a antenna list with it, does the board itself also come with an antenna array? If it does, what is the distance between different antennas? I will need it for the calculation of AoA.

Thanks!
