[0002] With the rapid development of modern society, the application of communication technology has become more and more popular, playing an increasingly important role in the fields of intelligence, automation, wireless control technology, etc. A tracking antenna (also known as a "surface antenna") forms a predetermined beam using a metal reflector, can absorb high-frequency microwave and millimeter-wave bands, greatly improving its reception efficiency and expanding the application field of the tracking antenna.

[0003] In the field of UAV applications, a method of using a tracking antenna to receive signals sent by UAVs has emerged, which can strengthen the control of UAVs and effectively receive UAV signals. Existing UAV tracking antennas are placed on the ground. When the UAV flies to the back of the transmitting surface, the signal reception ability of the transmitting surface decreases significantly, causing inconvenience in use. And since UAVs are mostly used outdoors, generally the tracking antenna is placed in an outdoor environment. However, due to the influence of weather changes in the outdoor environment, the outer surface of the tracking antenna is easily corroded, with a low service life. When reaching a certain number of years, the signal reception ability decreases significantly, and it needs to be replaced, resulting in high usage costs and being difficult to meet the long-term usage requirements of some devices.

[0036] Please refer to Figures 1 to 5, A tracking antenna, comprising a base 100, a reflector assembly 200 and a drive assembly 300. On opposite sides of the base 100, two foldable RTK antennas 110 are symmetrically arranged. The RTK antennas 110 are used for precise positioning of the aircraft. Their foldable structural design on the base 100 enables them to be folded and retracted onto the base 100 in a non-use state, avoiding damage. Moreover, a 4G antenna (not shown) is provided at the bottom of the base 100. The 4G antenna is used to connect to the data network to achieve network signal transmission with the aircraft and the outside. The reflector assembly 200 includes a rotating base 210, a reflector 220 and a fixed antenna 230. The rotating base 210 is rotatably connected to the base 100. The reflector 220 and the fixed antenna 230 are fixedly connected to the rotating base 210. A composite outer cover 120 is fixedly connected to the base 100. The composite outer cover 120 has a weak signal blocking effect and is made of a composite material with weak signal blocking ability. The reflector 220 and the fixed antenna 230 are arranged inside the composite outer cover 120. The composite outer cover 120 isolates the reflector 220 and the fixed antenna 230 from the external environment. The drive assembly 300 is arranged on the base 100 and is in transmission connection with the rotating base 210, and is used to drive the rotating base 210 to rotate, so as to rotate the reflector 220 on the rotating base 210, so that the reflector 220 moves with the aircraft to align with the signal emission direction of the aircraft, improving the signal reception ability.

[0037] Compared with the prior art, in the present invention, by providing the composite outer cover 120, the tracking antenna and the fixed antenna 230 are protected inside the composite outer cover 120, avoiding the erosion of the external environment on the reflector 220 and the fixed antenna 230, reducing the influence of the wind direction on the rotation of the arc-shaped reflector 220, ensuring stable rotation, prolonging the service life of the tracking antenna, and improving the reliability of the overall structure; and the present invention also sets the auxiliary antennas such as the RTK antenna 110 and the 4G antenna into a foldable structure, and the auxiliary antennas can be folded and retracted under necessary conditions to protect the antenna structure. The drive assembly 300 drives the reflector 220 to rotate, so that the reflector 220 always aligns with the aircraft direction, achieving the function of antenna tracking, improving the signal strength and ensuring the signal stability of the aircraft in all directions, without manual adjustment, and greatly improving the usability.

[0038] In an embodiment of the present invention, the reflector 220 is an arc-shaped reflector 220, and the horizontal cross-sectional shape thereof is a semi-circular surface. The fixed antenna 230 coincides with the rotation axis of the reflector 220 and rotates together with the rotating base 210. In addition, the fixed antenna 230 can also be fixed on the base 100 and is rotatably connected to the rotating base 210 to play a role in transmitting signals. The reflector 220 with an arc-shaped structure can enhance the signal reception ability of the present tracking antenna and better cover the received signals.

[0039] In another embodiment of the present invention, a driving pulley 330 is provided on the rotating base 210. The driving pulley 330 is rotatably connected to the base 100. In this embodiment, it is a synchronous pulley. The driving assembly 300 is connected to the driving pulley 330 through a synchronous belt to drive the driving pulley 330 to rotate, thereby adjusting the receiving angle of the reflecting surface 220 and realizing the signal reception of the aircraft.

[0040] Further, a driven pulley 310, a manual adjusting wheel 320, and an idler pulley 340 for tensioning the synchronous belt are rotatably provided on the base 100. The synchronous belt bypasses the driven pulley 310, the manual adjusting wheel 320, and the idler pulley 340 and then is connected to the driving pulley 330. The synchronous belt transmits the driving force of the driving assembly 300 to the rotating base 210 with small transmission loss. Moreover, a manual adjusting opening 130 is provided on the base 100, and the manual adjusting wheel 320 is exposed in the manual adjusting opening 130. People can rotate the manual adjusting wheel 320 through the manual adjusting opening 130 on the outside of the base 100, and then rotate the rotating base 210 to adjust the receiving angle of the reflecting surface 220, which has the function of manual adjustment while realizing the automatic adjustment of the driving assembly 300.

[0041] Specifically, an adjusting friction surface is provided on the manual adjusting wheel 320 so that people can contact and push the manual adjusting wheel 320 to rotate.

The wheel surface of the tensioning wheel 420 is a smooth surface or a toothed surface that matches the toothed belt surface of the synchronous belt. A position fixing structure is provided at the rotating connection between the rotating arm 410 and the base 100 for fixing the position of the tensioning wheel 420, thereby tensioning the synchronous belt.

[0043] Among them, the position fixing structure can be a fastening screw, which is threadedly connected to the rotating arm 410 and uses a pre-tightening force to fix the rotating arm 410 to achieve the tensioning effect. In addition, the position fixing structure can also be other fixing structures such as a buckle, which can also achieve the technical effect of fixing the position of the rotating arm 410 in the present invention.

The support frame 221 is fixedly connected to the rotating seat 210 to ensure the position between the composite outer cover 120 and the reflective surface 220, making the overall structure more reliable, reducing the shaking of the reflective surface 220 when rotating, maintaining the rotation accuracy, and playing a protective role when the tracking antenna is placed horizontally. Among them, the support frame 221 is composed of an adapter ring and a plurality of connecting rods connecting the adapter ring and the reflective surface 220, and the axis of the adapter ring coincides with the rotation axis of the reflective surface 220.

[0047] In addition, an electronic device layer is provided in the base 100, and an internal electronic module such as a processor is provided in the electronic device layer to realize the reception and processing functions of the tracking antenna signal and realize signal transmission, and the driving component 300 includes a driving motor, which is arranged in the electronic device layer and connected to the rotating seat 210 to drive the reflecting surface 220 to rotate.
