Description

Technical Field

[0001] This utility model relates to the field of omnidirectional antenna technology, and in particular to a dual-polarized omnidirectional antenna. Background Technology

[0002] Dual-polarized omnidirectional antennas are a widely used type of antenna in the field of wireless communication. They combine the characteristics of dual polarization and omnidirectional radiation. Dual polarization means that the antenna can radiate or receive signals in two mutually orthogonal polarization directions at the same time, usually horizontal polarization and vertical polarization. Compared with single-polarized antennas, dual-polarized omnidirectional antennas can better resist multipath fading and interference, and improve the stability and reliability of signal transmission.

[0003] In existing technologies, when using dual-polarized omnidirectional antennas, several single-layer dielectric substrates embedded with polarized elements (vertical or horizontal) are vertically assembled onto another skeleton dielectric substrate embedded with polarized elements (horizontal or vertical). However, since the size of the skeleton dielectric substrate is fixed and it does not have the ability to be spliced ​​and expanded, the overall size of the assembled antenna is limited by the inherent specifications of the skeleton dielectric substrate, and the antenna size cannot be flexibly adjusted according to the needs of the actual communication scenario.

[0004] Therefore, a dual-polarized omnidirectional antenna is proposed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of the overall size of the assembled antenna being limited by the inherent specifications of the frame medium board, making it impossible to flexibly adjust the antenna size according to the needs of actual communication scenarios, and to propose a dual-polarized omnidirectional antenna.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dual-polarized omnidirectional antenna, comprising a frame dielectric plate, a single dielectric plate slidably fitted on the surface of the frame dielectric plate, a first polarization vibrator embedded in the frame dielectric plate, a second polarization vibrator embedded in the single dielectric plate, an insert plate fixedly mounted on the surface of the frame dielectric plate, a slot adapted to the insert plate being provided on the side of the frame dielectric plate away from the insert plate, a pin slidably passing through the side wall of the frame dielectric plate, and a through hole adapted to the pin being provided on the surface of the insert plate.

[0007] The effect achieved by the above components is that, by setting up components such as insert boards, sockets and pins, multiple skeleton dielectric boards can be flexibly spliced ​​when assembling a dual-polarized omnidirectional antenna, and the antenna size can be flexibly adjusted according to the needs of the actual communication scenario, thereby improving the flexibility of the dual-polarized omnidirectional antenna.

[0008] Preferably, one end of the pin is fixedly fitted with an extension sleeve.

[0009] The effect achieved by the above components is as follows: when it is necessary to separate the skeleton medium plate, pull the extension sleeve, the extension sleeve will drive the plug rod to slide out from the through hole, and then the adjacent skeleton medium plate can be separated.

[0010] Preferably, a spring is fitted around the circumference of the pin, and the two ends of the spring are fixedly connected to the skeleton medium plate and the expansion sleeve, respectively.

[0011] The effect achieved by the above components is that when the spring contracts, the pin can slide into the through hole.

[0012] Preferably, the vertical cross-section of the insert plate is trapezoidal.

[0013] The effect achieved by the above components is that during the insertion process, the trapezoidal vertical plate will squeeze the pin and cause it to slide.

[0014] Preferably, the single-piece dielectric plate is internally threaded with a screw.

[0015] The effect achieved by the above components is that the screw can restrict the position of a single dielectric substrate.

[0016] Preferably, a connecting rod is fixedly mounted on one end of the screw, and a friction pad is fixedly mounted on one end of the connecting rod. The friction pad is slidably connected to the single-piece dielectric plate, and the friction pad abuts against the side wall of the skeleton dielectric plate.

[0017] The effect achieved by the above components is that after the connecting rod drives the friction pad to press tightly against the side wall of the skeleton medium plate, the static friction force is used to fix the single medium plate and prevent position displacement during operation.

[0018] Preferably, a limiting rod is fixedly mounted on the side of the skeleton medium plate away from the insert plate, and a limiting hole adapted to the limiting rod is opened on the side of the skeleton medium plate away from the limiting rod. One end of the limiting rod has a conical structure.

[0019] The effect achieved by the above components is that after the limiting rod is inserted into the limiting hole, it can prevent relative displacement after splicing and ensure structural accuracy.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting up components such as insert plates, sockets, and pins, multiple skeleton dielectric boards can be flexibly spliced ​​when assembling a dual-polarized omnidirectional antenna, and the antenna size can be flexibly adjusted according to the needs of the actual communication scenario, thereby improving the flexibility of the dual-polarized omnidirectional antenna.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] like Figures 1-4 As shown, this utility model provides a dual-polarized omnidirectional antenna, including a frame dielectric substrate 1, a single dielectric substrate 2 slidably fitted on the surface of the frame dielectric substrate 1, a first polarization vibrator 3 embedded in the frame dielectric substrate 1, a second polarization vibrator 4 embedded in the single dielectric substrate 2, an insert plate 5 fixedly mounted on the surface of the frame dielectric substrate 1, a slot 6 adapted to the insert plate 5 on the side of the frame dielectric substrate 1 away from the insert plate 5, a pin 7 slidably passing through the side wall of the frame dielectric substrate 1, and a through hole adapted to the pin 7 on the surface of the insert plate 5. By setting components such as the insert plate 5, the slot, and the pin 7, multiple frame dielectric substrates 1 can be flexibly spliced ​​when assembling the dual-polarized omnidirectional antenna, and the antenna size can be flexibly adjusted according to the needs of the actual communication scenario, thus improving the flexibility of the dual-polarized omnidirectional antenna.

[0026] As shown in Figure 4, one end of the pin 7 is fixedly fitted with an extension sleeve 8. When it is necessary to separate the skeleton medium plate 1, the extension sleeve 8 is pulled, and the extension sleeve 8 will drive the insertion rod to slide out of the through hole, and then the adjacent skeleton medium plate 1 can be separated. The circumferential surface of the pin 7 is fitted with a spring 9. The two ends of the spring 9 are fixedly connected to the skeleton medium plate 1 and the extension sleeve 8 respectively. When the spring 9 retracts, it can make the pin 7 slide into the through hole. The vertical cross section of the insertion plate 5 is trapezoidal. During the insertion process, the trapezoidal vertical cross section of the insertion plate 5 will squeeze the pin 7 to make it slide.

[0027] like Figures 1-3 As shown, a screw 10 is internally threaded onto a single-piece media plate 2. The screw 10 can restrict the position of the single-piece media plate 2. A connecting rod 11 is fixedly mounted on one end of the screw 10, and a friction pad 12 is fixedly mounted on one end of the connecting rod 11. The friction pad 12 is slidably connected to the single-piece media plate 2 and abuts against the side wall of the skeleton media plate 1. After the connecting rod 11 drives the friction pad 12 to press tightly against the side wall of the skeleton media plate 1, the single-piece media plate 2 is fixed by static friction to prevent position displacement during operation. A limiting rod 13 is fixedly mounted on the side of the skeleton media plate 1 away from the insert plate 5. A limiting hole 14 adapted to the limiting rod 13 is opened on the side of the skeleton media plate 1 away from the limiting rod 13. One end of the limiting rod 13 has a conical structure. After the limiting rod 13 is inserted into the limiting hole 14, it can avoid relative displacement after splicing and ensure structural accuracy.

[0028] The overall working principle is as follows: When assembling a dual-polarized omnidirectional antenna, the insert plate 5 of one skeleton medium board 1 is aligned with the slot 6 of another skeleton medium board 1 and inserted. During the insertion process, the trapezoidal vertical section of the insert plate 5 will press the pin 7 to slide, at which time the spring 9 will be stretched. When the insert plate 5 is fully inserted, the through hole coincides with the axis of the pin 7, and the spring 9 contracts to make the pin 7 insert into the through hole to complete the locking. At the same time, after the limiting rod 13 is inserted into the limiting hole 14, it can prevent relative displacement after splicing and ensure structural accuracy. Repeating the above operation can flexibly splice multiple skeleton medium boards 1 and adjust the overall size of the antenna. When it is necessary to disassemble the skeleton medium board 1, pull the extension sleeve 8. The extension sleeve 8 will drive the insert rod to slide out from the through hole, and then the adjacent skeleton medium boards 1 can be disassembled.

[0029] The single dielectric plate 2 is slidably fitted onto the surface of the skeleton dielectric plate 1, so that the second polarization oscillator 4 and the first polarization oscillator 3 reach the optimal orthogonal fit position, avoiding polarization interference. After the position is determined, the rotating screw 10 pushes the connecting rod 11 through the threaded transmission, causing the friction pad 12 to be tightly attached to the side wall of the skeleton dielectric plate 1. The single dielectric plate 2 is fixed by static friction, preventing position displacement during operation. Reverse rotation of the screw 10 can loosen the friction pad 12, making it easy to readjust the position and improving assembly flexibility.

[0030] The first polarization element 3 and the second polarization element 4 correspond to horizontal and vertical polarization (or vice versa) respectively, and are orthogonally distributed. During operation, they simultaneously radiate or receive orthogonally polarized signals, and the dual polarization characteristics cancel out multipath fading interference, improving the stability and reliability of signal transmission. Through the splicing and expansion capability of the skeleton dielectric substrate 1 and the positional adjustability of the single dielectric substrate 2, the arrangement spacing and number of the first polarization element 3 and the second polarization element 4 can be optimized according to the actual communication scenario or frequency band requirements, ensuring that the antenna can maintain good omnidirectional radiation characteristics under different sizes, and achieving all-round signal coverage without dead zones.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
