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.

Antenna, communication assembly, and unmanned aerial vehicle

An unmanned aerial vehicle (UAV) includes a fuselage, a power system arranged at the fuselage, and an antenna assembly arranged at the fuselage. The antenna assembly includes an antenna operating in a first frequency band and a second frequency band different from each other, a first parasitic unit configured to change a radiation direction of the antenna in the first frequency band, and a second parasitic unit configured to change a radiation direction of the antenna in the second frequency band.

Antennas and unmanned aerial vehicle

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&#xd7;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&#xd7;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.

Mobile object and antenna automatic alignment method and system thereof

A method is provided for controlling a signal transmission power of at least one of an unmanned aerial vehicle ('UAV') or a remote control device. The method includes determining whether a remote control distance between the UAV and the remote control device increases or decreases. The method also includes increasing or maintaining a signal transmission power of at least one of the UAV or the remote control device if the remote control distance increases. The method further includes decreasing or maintaining the signal transmission power of at least one of the UAV or the remote control device if the remote control distance decreases.

Control method, unmanned aerial vehicle, and remote control device

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.

An antenna automatic alignment method for a mobile object includes acquiring, in real time, current feature information of a plurality of antennas of the mobile object, and selecting one of the antennas to establish a communication link with a wireless terminal in accordance with the current feature information of the plurality of antennas.
