Abstract: An antenna automatic alignment method for a rotor unmanned aerial vehicle (UAV) includes acquiring current feature information of a plurality of antennas of the rotor UAV in real time. The antennas are disposed at substantially U-shaped landing gears of the rotor UAV. The method further includes selecting one of the antennas to establish a point-to-point communication link with a remote controller of the rotor UAV in accordance with the current feature information of the plurality of antennas. The antennas include spare antennas and current communication antennas, and a number of the spare antennas equals a number of the current communication antennas.

Abstract: An antenna includes a substrate and a dipole antenna disposed on a surface of the substrate. The dipole antenna includes a first metal structure and a second metal structure arranged symmetrically with respect to each other. The first metal structure includes a head proximal to the second metal structure, and a tail distal from the second metal structure. A width of the first metal structure varies between the head and the tail.

Abstract: A UAV system includes a remote controller including two first antennas and a UAV including two second antennas arranged at two landing stands of the UAV, respectively. The two first antennas and the two second antennas are configured to establish a 2×2 MIMO communication link. The remote controller is configured to transmit current terminal position information of the remote controller to the UAV via the 2×2 MIMO communication link. The UAV determines current remote controller relative position information of the remote controller relative to the UAV according to the current terminal position information and current UAV position information acquired via a position sensor, and controls communication between the UAV and the remote controller according to the current remote controller relative position information.
