IQ-Sampling with nRF5340DK

Hello,

im currently trying to setup a Project on my nRF5340 DK based on the direction finding samples from the SDK. As I understand from your tutorials an Antenna Matrix is needed to get enough I/Q-Samples for an algorithm to perform the angle calculations. My Question is if it is possible to extract I/Q-Data just from the antenna that is already on the nRF5340Dk Board and without an aditional antenna Matrix. The Example setup would be two devices that are connected and are sending CTE packets to each other and then are extracting the I/Q-Samples from these packages. I hope you understand what im trying to do. 

Best regards!

  • Thank you for your Answer. I understood why there is the need for multiple antennas, when you want to calculate the AoA or AoD. I need the IQ-Data from the devices for a different purpose. I want to send the constant tone extension on different frequency channels and then compare the received IQ-Samples for each channel. Therefore I would only need one antenna. But I'm not sure if this setup is possible.
