IWR6843AOP: antenna error parameters

Hi Yunlog,

I will look around to find out if this data is available?

Sami

Hi Yunlog,

Please check the data sheet (section 8.10.1) and here is what I was able to find.

Check this e2e thread.

IEEE paper provides coupling/isolation plots across frequency and lots more other details of the design.

Hi Sami,

Thanks for your reply. But I have not found an accurate antenna layout according to your answer. Because position error of antenna array have bad impact on DOA calculation.

Hi Yunlong,

This is the layout of the IWR6843AOP antennas.

Hi Sami,

Thanks for your reply. I know this layout, but I think this layout is an ideal model, not a parameter of the actual antenna layout.

For example, the actual distance between receiving antennas is not an ideal half-wavelength.

Do you have the actual antenna layout parameters?

Hi Yunlong,

I need to check.

Hi Sami, do you have any update?
