Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a tracking antenna structure. Background Technology

[0002] In wireless communication systems, antenna beamwidth directly affects signal coverage and transmission quality. Traditional fixed-beamwidth antennas often struggle to adapt to dynamically changing communication scenarios, such as when user density changes or service types switch, failing to flexibly adjust between wide-beam coverage and narrow-beam high gain. Related technologies typically require multiple independent antennas or complex array switching designs to achieve different beamwidth performances, leading to increased system size, higher costs, and more complex control. Therefore, there is an urgent need for a compact antenna solution capable of dynamically adjusting beamwidth to allow a single antenna to adapt to various communication needs at different times. Summary of the Invention

[0003] To achieve the above objectives, the present invention proposes a focusing antenna structure, comprising: substrate; Antenna unit, disposed on the support surface of the substrate; Isolation baffles are respectively set on both sides of the antenna unit and arranged perpendicularly to the support surface; A driving device is disposed on the support surface. The driving device is connected to the isolation baffle in a transmission manner, so that the isolation baffle is relatively displaced relative to the substrate in the normal direction of the support surface.

[0004] Specifically, the drive unit includes: The pull rod is located on the side of the isolation baffle facing away from the antenna unit, and the pull rod is arranged parallel to the support surface; The motor is connected to the pull rod drive, enabling relative displacement between the pull rod and the base plate; The gear bracket is located on the side of the isolation baffle facing away from the antenna unit. The gear bracket has a mounting groove, and a rotating shaft is installed in the mounting groove. The axis of the rotating shaft is perpendicular to the isolation baffle. The first gear and the second gear are respectively fitted onto the rotating shaft; The first rack is fixedly connected to the side of the isolation baffle facing the gear bracket. The first rack is perpendicular to the support surface and meshes with the first gear. The second rack is parallel to the tie rod and fixedly connected to it, and meshes with the second gear.

[0005] Specifically, the first rack is fixedly connected to the isolation baffle by the first rivet.

[0006] Specifically, the second rack is fixedly connected to the pull rod by the second rivet.

[0007] Specifically, the lever is made of glass.

[0008] The beneficial effects of the technical solution of this invention are as follows: By controlling the precise displacement of the isolation baffle through the driving device, the electromagnetic boundary conditions on both sides of the antenna element are dynamically changed, thereby achieving continuous adjustment of the beamwidth on a single antenna. This combines mechanical adjustment with electromagnetic performance, enabling an antenna to adapt to the different needs of coverage and signal strength at different times. It effectively solves the problems of large size, high cost and complex control caused by switching multiple antennas in traditional solutions. Attached Figure Description

When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.

[0015] Furthermore, the descriptions involving "first," "second," etc., in the embodiments of the present invention are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0016] To address the technical deficiencies in related technologies, this embodiment provides a focusing antenna structure, combined with... Figure 1 and Figure 2 As shown, the focusing antenna structure of this embodiment includes a substrate 100, on which a support surface is formed, and an antenna element 200 is disposed. Isolation baffles 300 are respectively disposed on both sides of the antenna element 200, and the isolation baffles 300 are arranged perpendicularly to the support surface. The focusing antenna structure of this embodiment also includes a driving device 400, which is disposed on the support surface and is drively connected to the isolation baffles 300, causing the isolation baffles 300 to be relatively displaced relative to the substrate 100 in the normal direction of the support surface.

[0017] Specifically, in this embodiment, the driving device 400 includes a pull rod 410 and a motor (not shown in the figure). The pull rod 410 is located on the side of the isolation baffle 300 facing away from the antenna unit 200, and the pull rod 410 is arranged parallel to the support surface. The motor is connected to the pull rod 410 for transmission, so that the pull rod 410 and the substrate 100 can be displaced relative to each other.

[0018] A gear bracket 420 is provided on the side of the isolation baffle 300 facing away from the antenna unit 200. The gear bracket 420 forms a mounting groove, and a rotating shaft is provided in the mounting groove. The axis of the rotating shaft is perpendicular to the isolation baffle 300. A first gear 430 and a second gear 440 are sleeved on the rotating shaft. The first gear 430 is closer to the isolation baffle 300 than the second gear 440. A first rack 450 is fixedly connected to the side of the isolation baffle 300 facing the gear bracket 420. The first rack 450 is perpendicular to the support surface and meshes with the first gear 430. A second rack 460 is parallel to and fixedly connected to the pull rod 410. The second rack 460 meshes with the second gear 440.

[0019] The first rack 450 is fixedly connected to the isolation baffle 300 by a first rivet, and the second rack 460 is fixedly connected to the pull rod 410 by a second rivet. The pull rod 410 is made of glass.

[0020] In this embodiment, the focusing antenna structure controls the precise displacement of the isolation baffle 300 through the driving device 400, dynamically changing the electromagnetic boundary conditions on both sides of the antenna element 200, thereby redistributing the radiation field of the antenna element 200. When the beamwidth of the antenna element 200 is adjusted to the target value, the displacement of the isolation baffle 300 is stopped. This allows a single antenna to adapt to the varying needs for coverage and signal strength at different times, effectively solving the problems of large size, high cost, and complex control caused by multi-antenna switching in traditional solutions.
