Description

Broadband multi-resonance 5G antenna system and base station
Technical Field
The utility model relates to a 5G communication technology field especially relates to a many resonance of broadband 5G antenna system and basic station.
Background
With the rapid development of wireless communication technology, fifth generation (5G) wireless communication systems will be commercialized in 2020. The 5G wireless communication system will use the following two different main frequency bands: below 6GHz and above 6 GHz. Since the coverage area is wide and the technology is mature under 6GHz (sub-6GHz), the 5G system under 6GHz will be preferentially used. In terms of the frequency range to be covered by Sub-6GHz, the 3GPP discloses that three frequency bands of 5G Sub-6GHz are as follows: n77 is 3.3 to 4.2GHz, N78 is 3.3 to 3.8GHz and N79 is 4.4 to 5.0 GHz. Each country can select a specific frequency band to be used from the three frequency bands according to specific conditions. For example, Korea will use the 3.4-3.6 GHz band; japan will use the 3.6-4.2 GHz band; china will use three frequency bands of 3.3-3.4 GHz, 3.4-3.6 GHz and 4.8-5.0 GHz. In addition, China Mobile will bring 2.515-2.675 GHz band into its 5G working band. Therefore, the 5G base station oscillator antenna of the sub-6GHz in China needs to cover a frequency band of 2.5-5.0 GHz. The application scenes of the 5G base station are diversified, and the requirement on the structural size of the antenna element of the 5G base station is higher and higher on many occasions, so that how to design a planar element antenna is a challenge to be faced in the design of a 5G base station antenna system. Another challenge faced in the 5G MIMO antenna system is how to design a wideband dipole antenna, so that the wideband dipole antenna can completely cover the 2.5-5.0 GHz band. In addition, in the case of satisfying the above-mentioned planarization and wide frequency, how to obtain a base station antenna system with better isolation (e.g. better than 20dB) will be another challenge in designing the base station element antenna. So far, although there are many designs of 5G base station element antennas, most of the bandwidths are too narrow. For example, chinese utility model patent publication No. CN207398340U discloses a 3.5G base station antenna radiation unit, the working frequency of which is 3.3-3.6 GHz and only has a bandwidth of 0.3 GHz; the chinese patent publication No. CN109037934A discloses a two-unit based 5G dual-band MIMO antenna, in which the working frequency bands of the antenna are 3.3 to 3.6GHz and 4.8 to 5.0GHz, respectively, and the frequency bands of 2.5 to 3.3GHz and 3.6 to 4.8GHz cannot be covered. Therefore, in order to meet the requirements of wide frequency and flatness of the 5G antenna system, it is necessary to design a planar element antenna capable of covering the entire 2.5 to 5.0GHz band. Furthermore, as mentioned above, another problem faced by base station antenna systems is how to reduce the isolation between antennas. The problem of reducing the isolation between antennas has been widely studied and discussed, for example by adding artificial magnetic conductors under the antennas, by adding isolating bars between two adjacent antenna element units, and by using isolating networks. No matter which kind of above-mentioned design is used, all can increase the complexity of antenna element and the degree of difficulty of design, still can increase the degree of difficulty for the debugging in later stage simultaneously.

To further illustrate the operation principle of the antenna system of this embodiment, fig. 5 is a schematic structural diagram of the antenna unit without the first radiator, fig. 6 is a schematic structural diagram of the antenna unit without the first protruding portion, the first radiator and the feeding component being T-shaped, fig. 7 is a comparison result of S11 of the antenna unit in fig. 5 and fig. 6, and it can be seen from fig. 7 that the antenna unit has a wider bandwidth due to the first protruding portion and the cross-shaped feeding structure. The first protruding part and the cross-shaped feed structure arranged in fig. 5 enable the second resonance of the antenna unit to be expanded from 3.67GHz to 3.84GHz, and the bandwidth expansion is very beneficial to the antenna frequency band coverage to reach the final design requirement of 2.5-5.0 GHz. The working principle of the antenna element in fig. 5 with two resonances is as follows: generating resonance with the resonant frequency of about 2.70GHz by one side of the second radiator close to the feed assembly; two sides of the second radiator which are axially symmetrical by taking the feed component as an axis generate resonance with the resonance frequency of about 3.84 GHz. Meanwhile, the isolation between the antenna units is close to about 25dB, and the design requirement of a base station antenna system can be well met.
Fig. 8 is an S-parameter diagram of the antenna element of fig. 2. It can be seen from the curves S11 and S22 in fig. 8 that the antenna elements resonate at 2.70GHz, 3.84GHz and 4.92GHz, respectively; as can be seen from the curves of S12 and S21, the isolation of the antenna in the frequency band of S11< -10dB is better than 23dB, and the design requirement is met. Comparing the curves S11 of fig. 7 and 8, it can be seen that fig. 8 has an additional resonance point of 4.92GHz, which is generated by the first radiator.
Fig. 9 shows a variation curve of the main shaft gain of the antenna unit in fig. 2 along with frequency, and the main shaft gain range of the antenna unit is 8.1 ± 0.5dBi in the whole 2.48-5.03 GHz frequency band, so as to meet the design requirements of the base station antenna. In summary, it is not difficult to see fig. 8 and fig. 9 that the antenna index of the present embodiment can completely meet the usage requirement of the 5G base station antenna system in the frequency band of 2.5 to 5.0 GHz.
In order to better explain the working principle of the antenna unit of the embodiment, fig. 10, fig. 11 and fig. 12 show the antenna current distribution diagrams in three different resonant frequency bands under the + 45-degree polarization condition. Wherein, a current distribution diagram of the antenna unit at the resonant frequency of 2.70GHz is given in FIG. 10; FIG. 11 shows a current distribution diagram of the antenna unit at a resonant frequency of 3.84 GHz; the current distribution diagram of the antenna element at the resonant frequency of 4.92GHz is given in fig. 12. From fig. 10 it is clear that the maximum intensity of the current distribution at the resonance frequency of 2.70GHz is concentrated in the part of the second radiator near the slot, which means that the resonance is mainly generated by this part of the structure of the antenna element. As can be seen from fig. 11, the maximum intensity of the current distribution at the resonant frequency of 3.84GHz is mainly concentrated at the outer part of the second radiator, so we can say that this resonance of 3.84GHz is generated by the outer side of the second radiator of the antenna element. As can be seen from fig. 12, the maximum intensity of the current distribution at the resonant frequency of 4.92GHz is concentrated in the loop formed between the second radiator and the first radiator of the antenna element, and therefore, we can say that this resonance of 4.92GHz is generated by the loop (dashed-line frame portion) of the antenna element.
Fig. 13 is a gain directional diagram of the antenna unit in fig. 2 in the major axis direction, and it can be seen from fig. 13 that the major axis gain of the main polarization is 8.3dBi, and the major axis gain of the cross polarization is-15.7 dBi, so that the cross polarization ratio of the antenna is 24dB, and the design requirement that the cross polarization ratio of the base station antenna should be not less than 15dB can be satisfied.
The base station in fig. 1 may adjust structural parameters of the antenna units, such as adding a spacer between the antenna units, adjusting the size of the space between the antenna units, and so on.
Fig. 14 is an E-plane radiation pattern (without downtilt) of the antenna system in fig. 1, and it can be seen from fig. 14 that, on the E-plane, the main lobe of the base station antenna is narrower without downtilt, the antenna radiation is mainly concentrated in the main axis direction, and the side lobe level is about 16.1dB, which can meet the requirement of the E-plane radiation pattern of the base station antenna and the design requirement that the side lobe level of the base station antenna should be not less than 15 dB. Fig. 15 is an H-plane radiation pattern (without downtilt) for the antenna system of fig. 1. As can be seen from fig. 15, on the H-plane, when there is no downward inclination, the radiation of the base station antenna is stable along the main axis direction, the half-power beam width is 65.3 °, and the requirement of the base station antenna H-plane radiation pattern and the design requirement that the half-power beam width of the base station antenna should be 65 ° ± 5 ° can be satisfied.
Therefore, the antenna unit of the present embodiment has a plurality of resonant frequency points, and achieves the effect of a wide frequency band by bringing different resonant frequencies close to each other. Because the antenna units of the embodiment can form +/-45-degree dual polarization and are in orthogonal relation in space, the antenna units of the embodiment have good isolation degree which is better than 23 dB.
To sum up, the utility model provides a pair of wide band multiresonance 5G antenna system and basic station, antenna unit can cover all frequency channels of 2.5 ~ 5GHz, has planarization, wide band and the stable characteristics of gain, and isolation between the antenna unit is good and its simple structure, and the cost of manufacture is low.
