My question is very simple. If antennas can only either transmit or receive at a time, why MIMO devices have separate antennas for transmitting and receiving? They are not used simultaneously.

Multiple antennas can transmit and receive at the same time, colloquially we can say each antenna is a 'chain'. This has value on multiple fronts, I highly suggest you read http://www.arubanetworks.com/assets/wp/WP_80211acInDepth.pdf

Maybe I didn't explain very well. I mean, if I am transmitting, I am not going to use my receiving antennas because no one else will be transmitting at the same time, otherwise collisions will occur. And if someone is transmitting and I am using my receiving antennas to listen to, I am not going to use my transmiting antennas because I am not going to transmit at that time, otherwise collisions will occur.
