Description

Technical Field

[0001] This utility model relates to the field of antenna technology, and in particular to a highly stable single-polarization omnidirectional ceiling antenna. Background Technology

[0002] Single-polarized ceiling antennas are mainly used in indoor wireless communication systems. Common application scenarios include large shopping malls, high-end residential areas, office buildings, hotels, conference centers, hospitals, and other places. They can effectively enhance the coverage and strength of wireless signals and provide stable communication connections.

[0003] In existing omnidirectional ceiling antennas, the connection between the radiating element and the grounding support plate is mostly achieved by punching three evenly distributed circular holes on the radiating element and riveting them together. This manufacturing method results in uneven contact between the radiating element and the grounding support plate because the radiating element is attached to the plane of the grounding support plate through an arc surface. Furthermore, the riveting stress and material rebound cause the riveting to be unstable, which in turn leads to unstable product performance. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of the prior art, this utility model provides a high-stability single-polarization omnidirectional ceiling antenna, which aims to solve the problem that the uneven bonding between the two surfaces caused by the arc surface of the radiating element and the plane of the grounding support plate of the element leads to the unstable performance of the product.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a high-stability single-polarization omnidirectional ceiling antenna, including a metal base plate, a radiating element and a coaxial cable.

The outer surface of the radiating element is provided with a planar groove corresponding to the first connecting block. The first connecting block is connected to the planar groove.

[0006] As a further improvement of this utility model, the planar groove is provided with a limiting part.

[0007] As a further improvement of this utility model: a first positioning hole is provided at the center of the planar groove, and the first connecting block is provided with a first positioning protrusion corresponding to the first positioning hole, the first positioning protrusion being connected to the first positioning hole. By providing a first positioning hole at the center of the planar groove and a first positioning protrusion corresponding to the first positioning hole on the first connecting block, the accurate assembly position of the vibrator grounding support plate and the radiating vibrator can be further ensured.

[0013] As a further improvement of this utility model: a first through hole is provided at the bottom center of the mounting groove, and a second through hole is provided on the single-sided copper-aluminum clad component. The inner conductor of the coaxial cable passes through the first through hole at the bottom of the mounting groove and the second through hole of the single-sided copper-aluminum clad component in sequence.

[0030] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. The present invention will now be further described in conjunction with the accompanying drawings and embodiments:

[0031] Please see Figure 1-8 A high-stability single-polarization omnidirectional ceiling antenna includes a metal base plate 5, a radiating element 3, and a coaxial cable 1. The metal base plate 5 and the radiating element 3 are connected by an element grounding support plate 4. One end of the element grounding support plate 4 is provided with a first connecting block 9. The outer surface of the radiating element 3 is provided with a planar groove 13 corresponding to the first connecting block 9. The first connecting block 9 is connected to the planar groove 13.

[0032] A planar groove 13 is provided on the outer surface of the radiating vibrator 3. The vibrator grounding support plate 4 is connected to the planar groove 13 of the radiating vibrator 3 through the first connecting block 9, which ensures that the first connecting block 9 of the vibrator grounding support plate 4 fits flatly with the planar groove 13 of the radiating vibrator 3, thereby improving the stability of product performance.

[0033] Instead of the traditional method of bonding the radiating vibrator 3 to the plane of the vibrator grounding support plate 4 via an arc surface, a planar groove 13 is opened in the radiating vibrator 3, and the radiating vibrator 3 is bonded to the plane of the vibrator grounding support plate 4 through the planar groove 13. This avoids the problem of unstable product performance caused by uneven bonding between the two surfaces of the radiating vibrator 3 and the vibrator grounding support plate 4.

[0034] Furthermore, the planar groove 13 is provided with a limiting part 14.

[0035] The limiting part 14 provided by the planar groove 13 can limit the first connecting block 9 and prevent the first connecting block 9 from rotating, so as to ensure that the assembly position of the vibrator grounding support plate 4 and the radiating vibrator 3 is accurate and no further adjustment is required.

[0036] Furthermore, a first positioning hole 17 is provided at the center of the planar groove, and the first connecting block 9 is provided with a first positioning protrusion 11 corresponding to the first positioning hole 17, and the first positioning protrusion 11 is connected to the first positioning hole 17.

[0037] By providing a first positioning hole 17 at the center of the planar groove and a first positioning protrusion 11 corresponding to the first positioning hole 17 in the first connecting block 9, the assembly position of the vibrator grounding support plate 4 and the radiating vibrator 3 can be further ensured.

[0038] Furthermore, to enhance the stability of product specifications, the original riveting method was changed to spot welding. Specifically, the first positioning protrusion 11 and the first positioning hole 17 are fixedly connected by welding.

[0039] By welding the first positioning protrusion 11 to the first positioning hole 17, the stability of the connection between the vibrator grounding support plate 4 and the radiating vibrator 3 is improved, production efficiency is increased, and the stability of product performance is enhanced.

[0040] Furthermore, the other end of the vibrator grounding support plate 4 is provided with a second connecting block 10, the second connecting block 10 is provided with a second positioning protrusion 12, the metal base plate 5 is provided with a second positioning hole 18 corresponding to the second positioning protrusion 12, and the second positioning protrusion 12 is connected to the second positioning hole 18.

[0041] A second connecting block 10 is provided at the other end of the vibrator grounding support plate 4. The second connecting block 10 is provided with a second positioning protrusion 12. The metal base plate 5 is provided with a second positioning hole 18 corresponding to the second positioning protrusion 12, which can ensure that the assembly position of the vibrator grounding support plate 4 and the metal base plate 5 is accurate.

[0042] Furthermore, the second positioning protrusion 12 and the second positioning hole 18 are fixedly connected by welding.

[0043] The second positioning protrusion 12 and the second positioning hole 18 are fixedly connected by welding, which improves the stability of the connection between the vibrator grounding support plate 4 and the metal base plate 5 and enhances the stability of the product.

[0044] Furthermore, the bottom of the radiating oscillator 3 is provided with a conical oscillator 19, which is connected to the inner conductor 15 of the coaxial cable 1.

[0045] To eliminate sources of instability, the original riveting method between the radiating vibrator 3 and the inner conductor 15 of the cable was changed to spot welding. This avoids the problem of loosening between the radiating vibrator 3 and the inner conductor 15 of the cable due to riveting stress and material springback after long-term use, which could lead to product performance instability and enhance the stability of product indicators. Specifically, the bottom of the conical vibrator 19 is provided with a mounting groove 16, and a single-sided copper-clad aluminum component 2 is welded to the mounting groove 16. The copper-clad surface of the single-sided copper-clad aluminum component 2 faces the open end of the radiating vibrator 3, and the inner conductor 15 of the coaxial cable 1 is fixed to the copper-clad surface of the single-sided copper-clad aluminum component 2 by welding.

[0046] The installation groove is welded with a single-sided copper-clad aluminum component. The inner conductor of the coaxial cable is fixed to the copper-clad surface of the single-sided copper-clad aluminum component by welding, which improves the stability of the connection between the radiating oscillator and the inner conductor of the cable and enhances the stability of the product.

[0047] Furthermore, a first through hole is provided at the bottom center of the mounting groove 16, and a second through hole is provided in the single-sided copper-aluminum clad component 2. The inner conductor 15 of the coaxial cable 1 passes through the first through hole at the bottom of the mounting groove 16 and the second through hole in the single-sided copper-aluminum clad component 2 in sequence.

[0048] Furthermore, a metal grounding component 7 is provided between the metal base plate 5 and the radiating vibrator 3. The metal base plate 5 is provided with a mounting hole 20. The coaxial cable 1 is connected to a connecting stud 8. The lower end of the metal grounding component 7 passes through the mounting hole 20 and is connected to the connecting stud 8.

[0049] Furthermore, the metal grounding component 7 and the connecting stud 8 are threaded together.

[0050] Furthermore, an insulating sheet 6 is provided between the radiating oscillator 3 and the metal grounding component 7.

[0051] This invention provides a high-stability single-polarization omnidirectional ceiling antenna that achieves high standing wave ratio, high intermodulation, and high stability at a relatively low cost.

[0052] The main functions of this utility model are:

[0053] This invention features a planar groove on the outer surface of the radiating vibrator. The vibrator grounding support plate is connected to this groove via a first connecting block, ensuring a smooth and flush fit between the first connecting block and the groove, thus improving product stability. A single-sided copper-clad aluminum component is welded to the mounting groove. The inner conductor of the coaxial cable is fixed to the copper-clad surface of the component by welding, further enhancing the stability of the connection between the radiating vibrator and the cable's inner conductor, and thus improving overall product stability.
