A dual hop, half‐duplex amplify and forward (AF) relay is considered for a source equipped with multiple transmit antennas. A power splitter is employed at the relay to harvest energy from the signal received from the source. The outage probability (OP) is derived considering optimal antenna selection to maximise the end‐to‐end signal‐to‐noise ratio. It is shown that the performance of the proposed energy harvesting based scheme improves with the number of transmit antennas. The effect of the power splitting factor on the OP is studied for different relay locations. Further, the OP is examined for different distances between the source and relay.
