The effect of the structure parameters such as antennas' distance and array of unmanned aerial vehicle-multiple input multiple output (UAV-MIMO) was analyzed for the improvement of the transmission capacity of the UAV telemetering link. And the three-dimensional geometrically based single bounce concentric elliptic ring scattering (GBSBCERS) channel model of UAV-MIMO was set up. Furthermore, the formula of UAV-MIMO correlation matrix and ergodic capacity was given combined with the layout scheme of airborne MIMO. The simulation results show that the UAV-MIMO channel capacity will increase along with the increase of antenna distance with the influence of UAV remote communication, and though the circular array layout is affected by the change of UAV attitude, it improves the channel capacity more significantly than linear array layout. The research of the influence of antennas structures on the UAV-MIMO channel capacity shows a practical significance in application on high-speed UAV data line design.
