IWR6843ISK-ODS: Changing the orientation of transmitter antenna and it's effect to 3d People counting

Hi Champ,

I would like to design ISK-ODS antenna with different input orientation (for ex Tx1 from bottom, Tx2 from top, etc) just like bellow,

My question is, will this TX orientation has any effect to the phase rotation, especially in 3d people counting phase rotation?

Thank you very much.
