|
|
I have been working on this 2x2 MIMO for LTE bands and isolation has been a continuous problem. I've been trying double slit's between the two antennas to help but without software I'm basically just shooting in the dark trying to find the right dimensions.
I recently tried adding a ferrite bead on the cable and so far it appears to have helped a tiny bit. However I have not had any luck finding any good research papers on it which leads me to believe there is a reason this isn't used in MIMO. If anybody has any information on the use of ferrite beads to improve isolation I would be greatly appreciative! |
