Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of communication antennas, in particular to a single-polarized dipole with a frequency of 1710 MHz - 2700 MHz. Background Art
[0002] With the full construction of 4G networks and 5G networks, the coverage of 4G signals and 5G signals in various scenarios has been fully carried out. The frequency bandwidth of base station antennas is getting wider and wider. As the main component of base station antennas, the frequency width supported by the dipole is particularly important. In the prior art, traditional dipoles have many defects. Usually, the structure of the dipole itself is relatively complex, which makes the production and forming process of the dipole complicated and lengthy, with a high production cost. Moreover, the size of the dipole itself is relatively large, resulting in poor stability during installation and use. Summary of the Utility Model
[0003] The technical problem to be solved by the utility model is how to provide a single-polarized dipole with a frequency of 1710 MHz - 2700 MHz, which has a simple structure, is easy to implement, and has a low cost.
[0004] To solve the above technical problem, the technical solution adopted by the utility model is: a single-polarized dipole with a frequency of 1710 MHz - 2700 MHz, including a dipole body and a coaxial cable. The dipole body includes a dielectric layer. On the upper surface of the dielectric layer, a radiation metal layer is formed on each of the left and right sides. On the lower surface of the dielectric layer, a back-matching metal layer is formed. The coaxial cable is located on the lower side of the dipole body. A metallized coaxial cable through-hole penetrating the dipole body is formed inside one of the radiation metal layers. A part of the braided layer at the upper part of the coaxial cable is exposed, so that the exposed part of the braided layer at the upper part of the coaxial cable passes through the coaxial cable through-hole, and the braided layer of the coaxial cable is welded to the radiation metal layer on this side through the coaxial cable through-hole. The wire core at the end of the coaxial cable is exposed, and the wire core is welded to the other radiation metal layer.
[0005] Preferably, the whole of the radiation metal layer is a rectangular structure with an inward extension.
[0006] A further technical solution is that the single-polarized dipole further includes two dipole fixing components. Three fixing component mounting holes penetrating the dipole body are formed on each of the radiation metal layers. The dipole fixing component includes a fixing bolt and a support column. After the fixing bolt passes through one of the fixing component mounting holes, it is threadedly connected to the upper end of the support column. The support column is used to support and fix the dipole body.
[0007] A further technical solution lies in that: two upper matching metal layers are formed on the upper surface of the dielectric layer between the two radiation metal layers.
[0008] Preferably, the overall shape of the upper matching metal layer is an equilateral triangle, and the long side of the upper matching metal layer is located outside the oscillator body.
[0009] A further technical solution lies in that: upper matching metal strips are formed on the upper surface of the dielectric layer outside the radiation metal layer. There are four upper matching metal strips, which are respectively located on the front and back sides of each radiation metal layer.
[0010] Preferably, the dielectric layer uses an FR4 insulating board. The length of the dielectric layer is 68 mm, the width is 22 mm, the thickness is 1.5 mm, and the dielectric constant is 4.4.
[0011] The beneficial effects of adopting the above technical solutions are as follows: Both the front and back of the oscillator body of this application are provided with feeding solder pad interfaces. Among them, the back solder pad interface is the solder pad interface for the braided layer of the coaxial cable (the coaxial cable passes through the hole), and the front solder pad interface is the solder pad interface for the core wire of the coaxial cable. In the single-polarized oscillator, the oscillator corresponds to the feeding point of the coaxial cable. When it receives the corresponding feeding energy, this feeding will be directly transmitted to the oscillator body, and the oscillator body will emit electromagnetic waves of 1710 MHz - 2700 MHz, thereby realizing the requirements of signal transmission and coverage. The oscillator of this application is extremely easy to implement due to its extremely simple structural form and has a low cost; it can emit and cover electromagnetic wave signals of 1710 MHz - 2700 MHz and is used for signal coverage in the 4G frequency bands of China Mobile, China Telecom, and China Unicom.

[0020] Next, in combination with the drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.
[0021] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar promotions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0022] As Figure 1 - Figure 2 shown, the embodiment of the present utility model discloses a single-polarized oscillator with a frequency of 1710 MHz - 2700 MHz. The single-polarized oscillator can transmit and cover electromagnetic wave signals of 1710 MHz - 2700 MHz, and is used for signal coverage of the 4G frequency bands of China Mobile, China Telecom, and China Unicom. The single-polarized oscillator includes an oscillator body 1 and a coaxial cable 2. The oscillator body 1 includes a dielectric layer 11. Preferably, the dielectric layer 11 can use an FR4 insulating board. The length of the dielectric layer 11 can be 68 mm, the width can be 22 mm, the thickness can be 1.5 mm, and the dielectric constant can be 4.4. It should be noted that those skilled in the art can appropriately adjust the specific parameters listed for the dielectric layer 11 as needed, which does not constitute a limitation here.
[0023] Furthermore, as Figure 1 - Figure 3As shown in the figure, a radiation metal layer 12 is formed on each of the left and right sides of the upper surface of the dielectric layer 11. The whole of the radiation metal layer 12 has a rectangular structure with inward extension parts. The extension parts on the radiation metal layer 12 are arranged oppositely and are not connected to each other. On the upper surface of the dielectric layer 11 between the two radiation metal layers 12, two upper matching metal layers 15 are formed. Preferably, the whole of the upper matching metal layer 15 is an equilateral triangle, and the long side of the upper matching metal layer 15 is located outside the oscillator body 1. On the upper surface of the dielectric layer 11 outside the radiation metal layer 12, upper matching metal strips 16 are formed. Preferably, four upper matching metal strips 16 are provided, which are respectively located on the front and back sides of each radiation metal layer 12.
[0024] As Figure 4 shown in the figure, a back matching metal layer is formed on the lower surface of the dielectric layer 11. Further, the back matching metal layer includes a lower matching metal layer 17 opposite to the position of the upper matching metal layer 15, and a lower matching metal strip 18 opposite to the position of the upper matching metal strip 16. The back matching metal layer cooperates with the upper matching metal layer 15 and the upper matching metal strips 16 on the front side to achieve signal matching.
[0025] Further, as Figure 1 and Figure 2 shown in the figure, the coaxial cable 2 is located on the lower side of the oscillator body 1. A metallized coaxial cable through hole 13 penetrating the oscillator body 1 is formed inside one of the radiation metal layers 12. A part of the braided layer 21 of the upper part of the coaxial cable 2 is exposed, so that the exposed part of the braided layer 21 of the upper part of the coaxial cable 2 passes through the coaxial cable through hole 13, and the braided layer 21 of the coaxial cable 2 is welded and connected to the radiation metal layer 12 on this side through the coaxial cable through hole 13. The core 22 at the end of the coaxial cable 2 is exposed, and the core 22 is welded and connected to the other radiation metal layer 12.
[0026] Further, as Figure 1 and Figure 2 shown in the figure, the single-polarization oscillator further includes two oscillator fixing components 3. Three fixing component mounting holes 14 penetrating the oscillator body 1 are formed on each radiation metal layer 12. The oscillator fixing component 3 includes a fixing bolt 31 and a support column 32. The fixing bolt 31 passes through one of the fixing component mounting holes 14 and is threadedly connected to the upper end of the support column 32. The support column 32 is used to support and fix the oscillator body 1.
[0027] In the single-polarized oscillator described in this application, the electrical signal is transmitted through the coaxial cable 2 to the radiation metal layer 12 on the oscillator body, generating electromagnetic waves radiated outward. The single-polarized oscillator with a frequency range of 1710 MHz - 2700 MHz provided in this application is extremely easy to implement because it adopts a minimalist structural form and all components except the oscillator itself are standard parts. Compared with traditional oscillators, this oscillator has a simple structure, a fast forming process, low cost, small size, and high stability.
