WI-FI //BT antenna in JTX1

Dear sir
I am using JTX1 module there are two connectors for wi fi Bluetooth can i use any one antenna for accessing both at the same time or a dedicated antenna for both the interfaces is required ?

Does this is for connecting mimo antennas?

Support is provided for platforms that share a single antenna between Bluetooth and WLAN. Yes, two antenna are used as 2 x 2 MIMO.
