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.

First claim

What is claimed is:

1. An unmanned aerial vehicle, including 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; wherein the horizontal direction of the unmanned aerial vehicle is perpendicular to the vertical direction of the unmanned aerial vehicle.

2. The unmanned aerial vehicle according to claim 1 , wherein
the unmanned aerial vehicle includes a body, and a first foot stand and a second foot stand disposed below the body, oppositely to each other;
the first dual-polarized antenna is horizontally provided in the first foot stand; and
the second dual-polarized antenna is vertically provided in the second foot stand.

3. The unmanned aerial vehicle according to claim 1 , wherein
the unmanned aerial vehicle includes a body, and a first foot stand and a second foot stand, disposed below the body, oppositely to each other; and
the first foot stand includes a first connection rack, a second connection rack, and a third connection rack, wherein the first connection rack, the second connection rack, and the third connection rack are sequentially connected, and wherein the first dual-polarized antenna is horizontally provided in the second connection rack, and the second dual-polarized antenna is vertically provided in the first connection rack or the third connection rack.

4. The unmanned aerial vehicle according to claim 2 , wherein several first limit columns are provided inside the first foot stand at intervals along an outline that defines the shape of the first foot stand, so as to limit the first dual-polarized antenna.

5. The unmanned aerial vehicle according to claim 3 , wherein several first limit columns are provided inside the first foot rest at intervals along an outline that defines the shape of the first foot rest, to locate the first dual-polarized antenna.

6. The unmanned aerial vehicle according to claim 1 , wherein the first dual-polarized antenna includes a first copper pipe and a first radio frequency cable;
one end of the first radio frequency cable is provided with a first radio frequency connector, and the other end of the first radio frequency cable is provided inside the first copper pipe; and
one end of the first copper pipe is provided with a first soldering tin pad, and the other end of the first radio frequency cable is provided with a second soldering tin pad; wherein a core cable of the first radio frequency cable passes through one end of the first copper pipe, and connects the core cable of the first radio frequency cable and the first copper pipe by the welding between the first soldering tin pad and the second soldering tin pad.

7. The unmanned aerial vehicle according to claim 6 , wherein the first dual-polarized antenna further includes a first heat-shrinkable sleeve, wherein the first copper pipe and the first radio frequency cable are both provided inside the first heat-shrinkable sleeve.

8. The unmanned aerial vehicle according to claim 7 , wherein the diameter of the core cable of the first radio frequency cable is 1.37 mm.

9. The unmanned aerial vehicle according to claim 2 , wherein several second limit columns are provided inside the second foot stand at intervals along an outline that defines the shape of the second foot stand, so as to limit the second dual-polarized antenna.

10. The unmanned aerial vehicle according to claim 3 , wherein several second limit columns are provided inside the second foot stand at intervals along an outline that defines the shape of the second foot stand, so as to limit the second dual-polarized antenna.

11. The unmanned aerial vehicle according to claim 1 , wherein the second dual-polarized antenna includes a second copper pipe and a second radio frequency cable;
one end of the second radio frequency cable is provided with a second radio frequency connector, and the other end of the second radio frequency cable is provided inside the second copper pipe; and
one end of the second copper pipe is provided with a third soldering tin pad, and the other end of the second radio frequency cable is provided with a fourth soldering tin pad; wherein a core cable of the second radio frequency cable passes through one end of the second copper pipe, and connects the core cable of the second radio frequency cable and the first copper pipe by the welding between the third soldering tin pad and the fourth soldering tin pad.

12. The unmanned aerial vehicle according to claim 11 , wherein the second dual-polarized antenna further includes a second heat-shrinkable sleeve, wherein the second copper pipe and the second radio frequency cable are both provided inside the second heat-shrinkable sleeve.
