Abstract: A wireless communication system and a drone system using the wireless communication system are provided. The wireless communication system includes a first communication module and a second communication module. The first communication module transmits a same signal in a first frequency band and a second frequency band respectively by means of power splitting and frequency conversion, the first frequency band being different from the second frequency band. The second communication module separately receives the signal transmitted by the first communication module in the first frequency band and the signal transmitted by the first communication module in the second frequency band, and converts the received signal of the second frequency band into the signal of the first frequency band through frequency conversion, and performs diversity reception with the received signal of the first frequency band.

Abstract: The present application relates to the field of unmanned aerial vehicle (UAV) technologies, and provides a motor control system and a UAV. The motor control system includes a control unit, a first inverter electrically connected to the control unit, a second inverter electrically connected to the control unit, a first motor electrically connected to the first inverter and a second motor electrically connected to the second inverter. According to the foregoing manner, two inverters in the motor control system are electrically connected to one control unit. Therefore, the control unit can control running of two motors, thereby reducing the volume of a hardware circuit board having the motor control system and reducing the weight.

Abstract: The present disclosure relates to the technical field of unmanned aerial vehicles, and in particular, to an unmanned aerial vehicle. The unmanned aerial vehicle includes at least a first dual-polarized antenna and a second dual-polarized antenna, wherein the first dual-polarized antenna is provided in a horizontal direction of the unmanned aerial vehicle, and the second dual-polarized antenna is provided in a vertical direction of the unmanned aerial vehicle. As the antenna designed in this structure is applied to the unmanned aerial vehicle of the present application, a weak signal in a vertical polarization direction is compensated by a strong electromagnetic signal in a horizontal polarization direction, and therefore an image transmission height of the unmanned aerial vehicle is increased in the vertical direction.

Abstract: The present application relates to the field of communications, and provides an antenna assembly which is disposed in a wireless communications electronic device. The wireless communications electronic device is provided with a substrate. The antenna assembly includes: a radiation element, disposed at a first surface of the radiation element; a feeder, electrically connected to the radiation element; and a reference ground, disposed at a second surface of the substrate. The antenna assembly in the embodiments of the present application uses the substrate of the wireless communications electronic device as a medium to bear the radiation element, reducing space and costs of the antenna assembly; and because the substrate is relatively thick, a bandwidth of the antenna assembly is also increased. The embodiments of the present application further provide a wireless communications electronic device having the antenna assembly.
