I see. Then I would recommend you to check out the Antenna Matrix from Insight SiP. Making your own would be a lot more expensive than simply getting one of those. Unfortunately, I can not help you when it comes to getting the reference design yourself.

Yeah, that whitepaper helped a lot, along with already answered questions here on DevZone.

Plans are to design entire AoA locator, use nRF52833 DK as Tag and for algorithm solution I'll probably use MUSIC or ESPRIT, but I'm aware of that there still might be factors that I didn't take into account and original plans might change. 🙂

Hello,

Sounds like you have an interesting project on your hands! There is a lot of good information available here on DevZone, so good thing that you've searched around here. Though I would also recommend our whitepaper on direction finding if you haven't seen it before.

When it comes to Question 2, are you planning on making the entire solution (angle algorithm etc.) yourself?

Regards,

Elfving
