Technical Field

[0001] This utility model relates to the field of antenna equipment technology, and in particular to a 5G full-band dual-polarized base station sector antenna. Background Technology

[0002] With the continuous development of mobile communication from 2G, 3G, 4G to 5G, mobile communication antennas have also undergone a development process from single-polarized antennas and dual-polarized antennas to smart antennas, MIMO antennas, and even massive MIMO antennas. As the sensing organs of mobile communication networks, antennas play an increasingly complex role and their function is becoming increasingly important.

[0003] Currently, the common antenna coverage frequency band is 1700-2700MHz, which is insufficient for current development needs. Therefore, it is necessary to design 5G full-band dual-polarized base station sector antennas to solve the above problems. Utility Model Content

[0004] The main purpose of this invention is to provide a 5G full-band dual-polarized base station sector antenna, which can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A 5G full-band dual-polarized base station sector antenna includes a reflector. Support columns are fixedly connected to both sides of the upper surface of the reflector. Printed vibrators are fixedly connected to the upper surface of the support columns. A grounding post is fixedly connected to the middle of the upper surface of the reflector, and the grounding post penetrates the reflector. A coaxial cable is fixedly connected to the side of the upper surface of the reflector near the grounding post. Four copper-clad elements are printed on the printed vibrator, and their arrangement resembles a four-leaf clover structure. Each vibrator blade is divided into a first copper-clad element, a second copper-clad element, a third copper-clad element, a fourth copper-clad element, an impedance adjustment section, a copper grounding plate, a signal feed plate, and a copper connecting plate.

[0007] In order to achieve the effect of adjusting the impedance within the frequency band, the impedance adjustment part of the 5G full-band dual-polarized base station sector antenna of this utility model is provided in four groups, and the four groups of impedance adjustment parts are evenly distributed on the four sides of the printed vibrator.

[0008] To facilitate signal transmission, the 5G full-band dual-polarized base station sector antenna of this utility model has two copper grounding plates, which are two grounding surfaces for two polarizations. The signal is transmitted to the second and fourth copper arrays through the copper holes.

[0009] In order to facilitate the connection between the signal feed plate and the first copper-plated array, the copper-plated connecting piece, as the sector antenna of the 5G full-band dual-polarized base station of this utility model, mainly serves to connect the signal feed plate and the first copper-plated array.

[0010] In order to achieve the effect of easy combination of symmetrical dipoles, as the 5G full-band dual-polarized base station sector antenna of this utility model, the first copper-clad array and the third copper-clad array form a symmetrical dipole with one polarization, and the second copper-clad array and the fourth copper-clad array form a symmetrical dipole with the other polarization.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. In this utility model, by setting up a reflector, support column, printed vibrator, grounding column and coaxial cable, a circuit board combination structure is adopted, and the radiating unit adopts a printed PCB clover structure. The bandwidth flatness is increased by reasonably gradient structure, so that the antenna covers the frequency band of 1700-2700 / 3300-4200MHz, which meets the needs of 5G communication systems in various countries. The 4G and 5G modules are integrated, so that 4G and 5G share a module to transmit signals, thereby saving the entire transmission system and power resources.

The copper-plated grounding plate, the second copper-plated array, and the fourth copper-plated array can form a good electromagnetic shielding effect, reducing the impact of external electromagnetic interference on signal transmission, and also preventing internal signals from interfering with the outside. The copper-plated connecting plate deposits a layer of copper on the hole wall and other positions through a chemical copper plating process, making the originally insulated area conductive.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example

[0023] like Figure 1-6 As shown, a 5G full-band dual-polarized base station sector antenna includes a reflector 1. Support columns 2 are fixedly connected to both sides of the upper surface of the reflector 1. Printed vibrators 3 are fixedly connected to the upper surface of the support columns 2. A grounding post 4 is fixedly connected to the middle of the upper surface of the reflector 1. The grounding post 4 penetrates the reflector 1. A coaxial cable 5 is fixedly connected to the side of the upper surface of the reflector 1 near the grounding post 4. Four copper-clad arrays are printed on the printed vibrator 3. Their arrangement resembles a four-leaf clover structure. Each vibrator blade is divided into a first copper-clad array 301, a second copper-clad array 302, a third copper-clad array 303, a fourth copper-clad array 304, an impedance adjustment part 305, a copper grounding piece 306, a signal feed piece 307, and a copper connecting piece 308.

[0024] In practical use, the antenna employs a circuit board assembly structure. The reflector 1, support column 2, printed transducer 3, grounding post 4, and coaxial cable 5 are arranged in a configuration. The reflector 1 is fixed to the printed transducer 3 via the support column 2. The grounding post 4 and coaxial cable 5 are soldered to the copper-clad surface of the printed transducer 3. The radiating element uses a printed PCB cloverleaf structure, and a rationally gradient structure increases bandwidth flatness, enabling the antenna to cover a frequency band of 1700-2700 / 3300-4200MHz, meeting the needs of 5G communication systems in various countries. By integrating 4G and 5G modules, both 4G and 5G share a single module for signal transmission, thus saving on the entire transmission system and power resources.

[0025] In this embodiment, four sets of impedance adjustment parts 305 are provided, and the four sets of impedance adjustment parts 305 are evenly distributed on the four sides of the printed oscillator 3.

[0026] In practical use, there are four pieces of the impedance adjustment section 305, which are distributed on the four sides of the printed oscillator 3. They mainly adjust the impedance in the 1700-2700 frequency band to make the entire frequency band relatively flat.

[0027] In this embodiment, two copper-plated grounding plates 306 are provided. The two copper-plated grounding plates 306 are two polarized grounding surfaces, and the signal is transmitted to the second copper-plated array 302 and the fourth copper-plated array 304 through the copper-plated holes.

[0028] In practical applications, the copper-plated grounding plate 306 can provide a low-impedance signal transmission path, reducing signal loss and reflection during transmission, thereby improving signal integrity and stability. The two copper-plated grounding plates 306 serve as two polarized ground planes, providing a stable reference potential for the signal, reducing grounding resistance, and reducing interference on the signal return path. The copper-plated grounding plate 306, the second copper-plated array 302, and the fourth copper-plated array 304 can form a good electromagnetic shielding effect, reducing the impact of external electromagnetic interference on signal transmission, and also preventing internal signals from interfering with external signals.

[0029] In this embodiment, the copper plating connector 308 mainly serves to connect the signal feed piece 307 and the first copper-plated array 301.

[0030] In practical use, the copper plating connector 308 deposits a layer of copper on the hole wall and other locations through a chemical copper plating process, making the originally insulated area conductive. This conductive layer can effectively conduct electrical signals, ensuring stable signal transmission between the signal feed plate 307 and the first copper-plated array 301, and improving the conductivity of the circuit.

[0031] In this embodiment, the first copper-clad array 301 and the third copper-clad array 303 form one polarized symmetrical oscillator, and the second copper-clad array 302 and the fourth copper-clad array 304 form the other polarized symmetrical oscillator.

[0032] In practical use, the first copper-clad element 301 and the third copper-clad element 303 form a symmetrical dipole with one polarization, and the second copper-clad element 302 and the fourth copper-clad element 304 form a symmetrical dipole with the other polarization. By forming a radiation field with a polarization direction through the two symmetrical dipoles, the antenna gain and radiation pattern convergence characteristics can be effectively improved, the anti-interference capability can be enhanced, and the multipath fading problem can be well solved.

[0033] Working Principle: In use, the polarization-one signal is transmitted through one of the 5-core coaxial cables to the first copper-plated array 301. The network cable is then transmitted through the copper-plated grounding plate 306 to the third copper-plated array 303, forming a symmetrical dipole with a wavelength of 1 / 2. A recessed area is cut in the middle of the dipole to allow signals in the 3300-4200 MHz frequency band to resonate well at this recessed area. Due to the large antenna bandwidth, the hollow area of ​​the blades must be optimized to match the impedance value within the 3300-4200 MHz frequency band, ensuring that the resistance value fluctuates around 50 ohms at this frequency. The 1700-2700 ohm resistance is compensated by adjusting the impedance section 305. The polarization-two signal is transmitted through another 5-core coaxial cable to the signal feed plate 307, and then through... The copper-plated connector 308 transmits the signal to the second copper-plated array 302, and the network cable transmits the signal to the fourth copper-plated array 304 through the copper-plated grounding plate 306, forming a symmetrical dipole with a wavelength of 1 / 2. A reasonable resonant point in the 3300-4200 MHz frequency band is split at the middle of the dipole. Due to the large antenna bandwidth, the hollow area of ​​the blades needs to be optimized to match the impedance value within the 3300-4200 MHz frequency band, so that the resistance value at this frequency fluctuates around 50 ohms. Then, the impedance part 305 is adjusted to compensate for the 1700-2700 ohm resistance, forming a subarray of a 5G full-band dual-polarized base station sector antenna, integrating 4G and 5G modules, so that 4G and 5G share a single module to transmit signals, thereby saving the entire transmission system and power resources.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
