Antenna Array feed point

[Suresh C]

Hi, I am using NRF52833 DK for Direction finding using AOA. I found silicon Labs antenna array have identical or symmetrical feed point orientation but in some antenna array their orientation are not identical. Will it affect our system in any manner. Do we need to take care of anything in software side when orientation are not identical.

how about your problem?can you control the antenna switching?

Antenna Switching is not the problem here, the orientation of feed points in the antenna array is the problem. There is no problem with silicon lab antenna array because the feed points are in same orientation. I am using Core Hw 4x4 antenna array and the feed points orientation are not same.
