Hi @leapslabs
I had also thought that the radiation pattern of the antenna gain is an important factor in UWB ranging accuracy, but I did not know that the relative distance changes nonlinearly. Thank you very much for the information.
Therefore, what can an engineer do to improve the accuracy of ranging is not to correct the antenna, but to improve the accuracy of anchor position measurement and to place the anchor in the LOS environment as much as possible?
Please let me know if there is any relevant documentation.
I’ve looked over the mdek1001, dwm1001, and dw1000 manuals.
