Isolation for antennas in a wireless communication system is achieved between transmit and receive paths for a multiple input multiple output (MIMO) antenna array by separating a first transmit path from an associated receive path to be matched with a second transmit path and matching the first receive path with the second receive path. It is expected that the two transmit paths operate on sufficiently different frequencies that there is minimal interference there and the additional spacing from the transmit path to the receive path will reduce interference therebetween without increasing a footprint of the antenna array.
