Spacing between antennas for MIMO systems.

What is the spacing between antenna for MIMO systems? λ/4? If it is λ/4, what is the reason then? Thx.

Hi cwj, I have spent so much time to find a sensible answer for that question of yours, but couldnt.
Take a look at the following discussion that I started a couple of months ago, I hope it helps

Hi,

the antennas shouldn't be correlated (whatever this means). Perhaps you can understand better then me from the file attached.
