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 its installation and use. Summary of the Utility Model

Four discrete support columns are formed on the mounting base. At the upper end of each support column, a radiation plate is formed. The four radiation plates do not directly contact each other. A coaxial cable installation groove is formed on the side surface of each support column. The first radiation plate and the third radiation plate are arranged diagonally, and the second radiation plate and the fourth radiation plate are arranged diagonally. The upper end of the first coaxial cable passes through the coaxial cable installation groove on the support column under the first radiation plate, so that the core of the upper end of the first coaxial cable extends out from the upper surface of the first radiation plate.

The core of the upper end of the second coaxial cable and the second protrusion are connected together through a second connecting piece. The first connecting piece and the second connecting piece do not contact each other.

Specific implementation manners
[0021] Next, in combination with the accompanying 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 of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present utility model.
[0022] 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.
[0023] Such as Figures 1 - 6As shown, an embodiment of the present utility model discloses a dual-polarized oscillator with a frequency of 1710 MHz - 2700 MHz. The dual-polarized oscillator can emit electromagnetic waves with a frequency of 1710 MHz - 2700 MHz and is applicable to cover frequency bands B1, B3, B34, B39, B40, B41, N1, and N41 (including the 4G frequency bands of the three major operators, namely China Telecom, China Mobile, and China Unicom). The dual-polarized oscillator includes a mounting base 1, and four discrete support columns 2 are formed on the mounting base 1. At the upper end of each support column 2, a radiation plate is formed. Preferably, the overall shape of the radiation plate is a square structure, and of course, it can also be other shapes. The four radiation plates do not directly contact each other. Among them, the mounting base 1, the support columns 2, and the radiation plates can be integrally formed by die-casting aluminum alloy, with high processing efficiency and good consistency. A coaxial cable installation groove 4 is formed on the side of each support column 2. The first radiation plate 5 and the third radiation plate 6 are arranged diagonally, and the second radiation plate 7 and the fourth radiation plate 8 are arranged diagonally. Among them, the coaxial cable installation groove 4 located under the first radiation plate 5 and the second radiation plate 7 penetrates through the first radiation plate 5 and the second radiation plate 7 for the core of the corresponding coaxial cable to extend out of the corresponding radiation plate.
[0024] As Figure 2 and Figure 4 shown, the upper end of the first coaxial cable 9 passes through the coaxial cable installation groove 4 on the support column under the first radiation plate 5, so that the core 10 at the upper end of the first coaxial cable 9 extends out from the upper surface of the first radiation plate 5; a first protrusion 11 is formed at the corner of the third radiation plate 6 close to the first radiation plate 5, and the core 10 at the upper end of the first coaxial cable 9 is connected to the first protrusion 11 through a first connecting piece 12; the upper end of the second coaxial cable 13 passes through the coaxial cable installation groove 4 on the support column 2 under the second radiation plate 7, so that the core 10 at the upper end of the second coaxial cable 13 extends out from the upper surface of the second radiation plate 7. A second protrusion 14 is formed at the corner of the fourth radiation plate 8 close to the second radiation plate 7, and the core 10 at the upper end of the second coaxial cable 13 is connected to the second protrusion 14 through a second connecting piece 3; the first connecting piece 12 and the second connecting piece 3 do not contact each other.
[0025] One of the electromagnetic wave signals is transmitted to the first radiation plate 5 and the third radiation plate 6 through the first coaxial cable 9, so that the first radiation plate 5 and the third radiation plate 6 emit electromagnetic wave signals with corresponding frequencies. Another electromagnetic wave signal is transmitted to the second radiation plate 7 and the fourth radiation plate 8 through the second coaxial cable 13, so that the second radiation plate 7 and the fourth radiation plate 8 emit electromagnetic wave signals with corresponding frequencies.
[0026] Further, as Figure 2 and Figure 6As shown, the upper surface of the first radiation plate 5 is horizontally arranged and three arc-shaped holes are formed thereon. The specific shape of the arc-shaped holes can be adjusted accordingly as required. The height of the core 10 at the upper end of the first coaxial cable 9 is higher than the height of the first radiation plate 5, and the core 10 at the upper end of the first coaxial cable 9 is welded to the first connecting piece 12. Further, the upper surface of the third radiation plate 6 is horizontally arranged, and three arc-shaped holes are formed at positions symmetrical to the arc-shaped holes on the first radiation plate 5. The height of the first protrusion 11 is higher than the height of the third radiation plate 6, and the first protrusion 11 is welded to the first connecting piece 12.
[0027] Further, as Figure 2 and Figure 6 shown, a notch is formed at the corner of the second radiation plate 7 near the inner side. The core 10 at the upper end of the second coaxial cable 13 extends out from the coaxial cable mounting groove 4 under the second radiation plate 7. The core 10 at the upper end of the second coaxial cable 13 is welded to the second connecting piece 3. Three arc-shaped holes are formed on the second radiation plate 7. A notch is formed at the corner of the fourth radiation plate 8 near the inner side. The second protrusion 14 is located on this notch. The second protrusion 14 is welded to the second connecting piece 3, and three arc-shaped holes are formed thereon. Further, as Figure 3 shown, two fixing columns 15 are formed on the lower side of the mounting seat 1 to facilitate the fixation of the dual-polarization dipole.
[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
