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 698 MHz - 960 MHz. Background Art
[0002] With the full construction of the 5G communication network, the 5G signal coverage work in various scenarios has been fully carried out. Along with the addition of 5G communication frequencies, 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, its production cost is relatively high, and the size of the dipole itself is relatively large, resulting in poor stability during its 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 698 MHz - 960 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 698 MHz - 960 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. The coaxial cable is located on the lower side of the dipole body. A 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. 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] A further technical solution lies in that: the whole of the radiation metal layer is a U-shaped structure with an opening facing outwards.
[0006] A further technical solution lies in that: the single-polarized dipole further includes two dipole fixing components. A fixing component installation hole penetrating the dielectric layer is arranged inside the U-shaped opening of each radiation metal layer. The dipole fixing component includes a fixing bolt and a support column. After the fixing bolt passes through the fixing component installation hole, it is threadedly connected to the support column. The support column is used to support and fix the dipole body.
[0007] A further technical solution lies in that: two matching metal layers are formed on the upper surface of the dielectric layer between the two radiation metal layers.
[0008] A further technical solution lies in that: a matching metal strip is formed on the upper surface of the dielectric layer outside the radiation metal layer.
[0009] Preferably, the dielectric layer has a length of 154 mm, a width of 51 mm, a thickness of 1.5 mm, and a dielectric constant of 4.4.
[0010] The beneficial effects produced by adopting the above technical solution are as follows: In the single-polarized oscillator of the present application, at the feeding point of the oscillator corresponding to the coaxial cable, when it receives the corresponding feeding energy, the feeding will directly transmit the energy to the oscillator body. After receiving the energy, the oscillator body will emit electromagnetic waves of 698 MHz - 960 MHz, thereby realizing the requirements of signal transmission and coverage. The oscillator of the present application is easy to implement and has a low cost due to its extremely simple structural form; it can be used for signal coverage in the 3G, 4G, and 5G frequency bands of China Mobile, China Telecom, and China Unicom.

[0017] The following clearly and completely describes the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts fall within the protection scope of the present utility model.
[0018] In the following description, many specific details are set forth to facilitate a thorough understanding of 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 extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0019] As Figure 1 - Figure 2 shown, an embodiment of the present utility model discloses a single-polarized oscillator with a frequency of 698 MHz - 960 MHz. The single-polarized oscillator emits electromagnetic wave signals in the frequency band of 698 MHz - 960 MHz and is used for signal coverage of various system frequency bands of China Telecom, China Mobile, and China Unicom. Specifically, the single-polarized oscillator includes an oscillator body 1 and a coaxial cable 2. The oscillator body 1 is used to generate electromagnetic waves, and the coaxial cable 2 is used to transmit energy to the oscillator body. The oscillator body 1 includes a dielectric layer 11. Preferably, the dielectric layer 11 can be made of an FR4 insulating board. Further, the length of the dielectric layer 11 can be 154 mm, the width can be 51 mm, the thickness can be 1.5 mm, and the dielectric constant is 4.4. It should be noted that the specific parameters of the dielectric layer 11 listed above do not limit this application, and those skilled in the art can also make appropriate adjustments according to actual needs.
[0020] Further, as Figure 1 - Figure 2 shown, on the upper surface of the dielectric layer 11, a radiation metal layer 12 is formed on each of the left and right sides. Preferably, the overall radiation metal layer 12 is a U-shaped structure with an opening facing outward. On the upper surface of the dielectric layer 11 between the two radiation metal layers 12, two matching metal layers 15 are formed. Preferably, the overall matching metal layer 15 is triangular, and a rectangular opening is formed on the matching metal layer 15. On the upper surface of the dielectric layer 11 outside the radiation metal layer 12, a matching metal strip 16 is formed. Four matching metal strips 16 are provided, respectively located on the front and back sides of each radiation metal layer 12.
[0021] Further, as Figure 1 - Figure 2 shown, the coaxial cable 2 is located below the oscillator body 1. A 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 at the upper part of the coaxial cable 2 is exposed, so that the exposed part of the braided layer 21 at 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 to the radiation metal layer 12 on this side. The core 22 at the end of the coaxial cable 2 is exposed, and the core 22 is welded to the other radiation metal layer 12.
[0022] Further, as Figure 1 - Figure 2As shown, the single-polarization oscillator further includes two oscillator fixing components 3. A fixing component mounting hole 14 penetrating through the dielectric layer 11 is provided in the U-shaped opening of 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 the fixing component mounting hole 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.
[0023] In the single-polarization oscillator of the present application, the electrical signal is transmitted to the radiation metal layer 12 on the oscillator body through the coaxial cable 2, generating electromagnetic waves radiated outward. The single-polarization oscillator with a frequency of 698 MHz - 960 MHz provided by the present application is extremely easy to implement because of its extremely simple structural form (all 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.
