[0026] As Figure 1 and Figure 2As shown, the application provides a vibrator unit, and embodiments of the vibrator unit of the application include: a first vibrator 10, a second vibrator 20, a third vibrator 30, and a fourth vibrator 40; the first vibrator 10 extends along a first direction a and is located in a first plane; the second vibrator 20 extends along a second direction b and is located in a second plane, the second vibrator 20 is crossly arranged with the projection of the first vibrator 10 in the second plane, and the first direction a and the second direction b are perpendicular to each other; the third vibrator 30 extends along a third direction c and is located in a third plane, and the third direction c forms a 45° angle with the first direction a and the second direction b; the fourth vibrator 40 extends along a fourth direction d and is located in a fourth plane, and the fourth direction d is perpendicular to the third direction c, wherein the first plane, the second plane, the third plane, and the fourth plane are arranged in parallel, and the first plane and the second plane are arranged in a spaced manner.

[0027] By applying the technical scheme of the embodiment, the first vibrator 10 extends along the first direction a and is located in the first plane, the second vibrator 20 extends along the second direction b and is located in the second plane, the second vibrator 20 is crossly arranged with the projection of the first vibrator 10 in the second plane, and the first direction a and the second direction b are perpendicular to each other, the characteristics (such as the frequency, amplitude, phase difference, etc. of the radiated wave) of the electromagnetic waves radiated by the first vibrator 10 and the second vibrator 20 can be modulated to make the first vibrator 10 and the second vibrator 20 radiate horizontally polarized and vertically polarized electromagnetic waves or circularly polarized electromagnetic waves, the third vibrator 30 extends along the third direction c and is located in the third plane, and the third direction c forms a 45° angle with the first direction a and the second direction b, the third vibrator 30 can radiate positively 45° polarized electromagnetic waves, the fourth vibrator 40 extends along the fourth direction d and is located in the fourth plane, and the fourth direction d is perpendicular to the third direction c, the fourth vibrator 40 can radiate negatively 45° polarized electromagnetic waves, and the first vibrator 10, the second vibrator 20, the third vibrator 30, and the fourth vibrator 40 arranged as above can radiate electromagnetic waves of multiple polarizations, so that the vibrator unit can meet the coverage effect required in the low-altitude application scenario; in addition, the multiple vibrators are reasonably arranged in the vibrator unit, so that the size of the vibrator unit is small under the condition of radiating electromagnetic waves of multiple polarizations, thereby effectively saving the tower resources. Therefore, the technical scheme of the embodiment can effectively solve the problem that the vibrator unit in the related art cannot balance stable transmission and miniaturization.

[0028] It should be noted that in the embodiment, the second plane, the third plane, and the fourth plane are coplanarly arranged, and in other embodiments, the second plane, the third plane, and the fourth plane can be all arranged in a spaced manner or two of them can be arranged in a spaced manner.

[0029] In addition, in the embodiment, as Figure 1As shown, the vibrator unit 90 further comprises an excitation structure 50 electrically connected with the first vibrator 10 and the second vibrator 20 to enable the first vibrator 10 to radiate the first electromagnetic wave and the second vibrator 20 to radiate the second electromagnetic wave, wherein the first electromagnetic wave has the same frequency as the second electromagnetic wave and a phase difference of +90° or -90°.

[0030] In this way, the first vibrator 10 and the second vibrator 20 cooperate to radiate circularly polarized electromagnetic waves. Specifically, the first vibrator 10 and the second vibrator 20 each have a feed port, and the excitation structure 50 comprises a bridge which is used to feed the feed port of the first vibrator 10 and the feed port of the second vibrator 20. The bridge has two input ports and two output ports, wherein the two output ports are electrically connected with the feed port of the first vibrator 10 and the feed port of the second vibrator 20 respectively. When a current is fed into one of the input ports of the bridge, the two output ports generate currents with a phase difference of 90°. At this time, the current on the feed port of the second vibrator 20 leads the current on the feed port of the first vibrator 10 by 90° in phase. In the case that the feeding current has the same amplitude and a phase difference of 90° (i.e. the first electromagnetic wave has the same frequency as the second electromagnetic wave and a phase difference of +90°), the first vibrator 10 and the second vibrator 20 can radiate left-handed circularly polarized electromagnetic waves. Similarly, when a current is fed into the other input port of the bridge, the two output ports generate currents with a phase difference of -90°. At this time, the current on the feed port of the second vibrator 20 lags behind the current on the feed port of the first vibrator 10 by -90° in phase. In the case that the feeding current has the same amplitude and a phase difference of -90° (i.e. the first electromagnetic wave has the same frequency as the second electromagnetic wave and a phase difference of -90°), the first vibrator 10 and the second vibrator 20 can radiate right-handed circularly polarized electromagnetic waves. In addition, the feed port of the second vibrator 20 is excited to enable the second vibrator 20 to radiate vertically polarized electromagnetic waves, and the feed port of the first vibrator 10 is excited to enable the first vibrator 10 to radiate horizontally polarized electromagnetic waves.

[0031] Therefore, the vibrator unit 90 applied in the embodiment can enable the vibrator unit 90 to radiate electromagnetic waves with positive 45° polarization, negative 45° polarization, vertical polarization and horizontal polarization, and can also enable the vibrator unit 90 to radiate electromagnetic waves with positive 45° polarization, negative 45° polarization, left-handed circular polarization and right-handed circular polarization.

[0032] As Figure 1As shown, the first vibrator 10 and the second vibrator 20 have a crossing point, the third vibrator 30 is at a distance from the crossing point equal to the distance of the fourth vibrator 40 from the crossing point. It should be noted that the "first vibrator 10 and the second vibrator 20 have a crossing point" refers to the intersection of the projection of the first vibrator 10 on the second plane and the second vibrator 20, and such arrangement makes the center of the electromagnetic wave synthesized by the electromagnetic wave radiated by the third vibrator 30 and the electromagnetic wave radiated by the fourth vibrator 40 coincide with the crossing point, and further makes the center of the electromagnetic wave synthesized by the four coincide with the center of the first vibrator 10 and the second vibrator 20 (that is, the crossing point).

[0033] As shown in FIG. 1, the vibrator unit 90 includes a first vibrator 10, a second vibrator 20, a third vibrator 30, and a fourth vibrator 40. Figure 1 As shown, the vibrator unit 90 further includes a fifth vibrator 60, which is located in the third plane and is arranged in parallel with the third vibrator 30. In addition, in this embodiment, the vibrator unit 90 further includes a sixth vibrator 70, which is located in the fourth plane and is arranged in parallel with the fourth vibrator 40. That is, the third vibrator 30 and the fifth vibrator 60 form a first vibrator group, the fourth vibrator 40 and the sixth vibrator 70 form a second vibrator group, and the first vibrator group and the second vibrator group form a quasi-square structure, the geometric center of which coincides with the crossing point. Meanwhile, the feed port of the third vibrator 30 and the feed port of the fifth vibrator 60 are excited so that the first vibrator group can radiate electromagnetic waves with a positive 45° polarization, and the feed port of the fourth vibrator 40 and the feed port of the sixth vibrator 70 are excited so that the second vibrator group can radiate electromagnetic waves with a negative 45° polarization.

[0034] In addition, the excitation structure 50 is electrically connected to the third vibrator 30 and the fifth vibrator 60 so that the third vibrator 30 can radiate a third electromagnetic wave and the fifth vibrator 60 can radiate a fifth electromagnetic wave, wherein the third electromagnetic wave and the fifth electromagnetic wave have the same frequency and a phase difference of 0; the excitation structure 50 is electrically connected to the fourth vibrator 40 and the sixth vibrator 70 so that the fourth vibrator 40 can radiate a fourth electromagnetic wave and the sixth vibrator 70 can radiate a sixth electromagnetic wave, wherein the fourth electromagnetic wave and the sixth electromagnetic wave have the same frequency and a phase difference of 0.

[0035] As shown in FIG. 1, the vibrator unit 90 includes a first vibrator 10, a second vibrator 20, a third vibrator 30, and a fourth vibrator 40. Figure 1 As shown, in this embodiment, the third vibrator 30 is at a distance from the crossing point equal to the distance of the fifth vibrator 60 from the crossing point. Specifically, such arrangement makes the center of the electromagnetic wave generated by the first vibrator group located at the crossing point; the fourth vibrator 40 and the sixth vibrator 70 are also arranged in the same way.

[0036] As shown in FIG. 1, the vibrator unit 90 includes a first vibrator 10, a second vibrator 20, a third vibrator 30, and a fourth vibrator 40. Figure 1As shown in the figure, in the embodiment, the distance between the third vibrator 30 and the fifth vibrator 60 is half of the wavelength of the third electromagnetic wave. In this way, the wave crest of the third electromagnetic wave and the wave crest of the fifth electromagnetic wave meet at the intersection point, thereby achieving the effect of electromagnetic wave superposition, thereby enhancing the intensity of the electromagnetic wave generated by the first vibrator group, and the fourth vibrator 40 and the sixth vibrator 70 are also arranged in this way.

[0037] As shown in the figure, Figure 1 and Figure 2 The vibrator unit 90 also includes a reflecting plate 80, which is spaced apart from the first plane and the second plane in the direction perpendicular to the first plane, and the first plane and the second plane are located on the same side of the reflecting plate 80. The arrangement of the reflecting plate 80 enables part of the spatial wave generated by the vibrator to be emitted at the reflecting plate 80, so that this part of the reflected component is combined with other components, thereby enhancing the overall intensity of the vibrator unit.

[0038] As shown in the figure, Figure 2 The second plane is located between the reflecting plate 80 and the first plane, and the distance between the second plane and the reflecting plate 80 is half of the wavelength of the first electromagnetic wave. In the embodiment, since the distance between the first vibrator group, the second vibrator group and the second vibrator 20 and the reflecting plate 80 is equal and is half of the wavelength of the electromagnetic wave radiated by each of them, and the frequency and amplitude of the electromagnetic wave radiated by each vibrator are the same, the part of the electromagnetic wave radiated by the vibrator and the other components reflected by the reflecting plate 80 meet the wave crest at the vibrator, thereby enhancing the intensity.

[0039] The application also provides an antenna structure, and the antenna structure includes a vibrator unit. The vibrator unit is the vibrator unit described above. The vibrator unit described above can effectively solve the problem that the vibrator unit in the related art cannot balance stable transmission and miniaturization, and the antenna structure with the vibrator unit described above also has the advantages described above.

[0040] As shown in the figure, Figure 3As shown, the vibrator units 90 are multiple, and the multiple vibrator units 90 are arranged in an N-row*M-column manner, where N and M are both positive integers greater than 0. The arrangement of the multiple vibrator units 90 can enhance the strength of the electromagnetic waves radiated by the antenna structure, and make the synthesized electromagnetic waves more uniform. In addition, the arrangement of the multiple vibrator units 90 forms MIMO (MIMO is the abbreviation of Multiple Input Multiple Output, which refers to a multiple input multiple output technology. In the field of communication, MIMO technology is a technology for signal transmission and reception using multiple antennas to improve the data transmission rate and signal coverage range of the communication system. By using multiple antennas to simultaneously send and receive signals, MIMO technology can significantly improve the performance and reliability of the communication system), compared with the antenna structure in the related art, the area of the antenna structure is reduced by half under the same required port number, and the miniaturization effect of the antenna structure is significant.

[0041] As shown in Figure 3 The vibrator unit 90 can radiate vibrator unit electromagnetic waves, and in the N-row vibrator unit 90, the distance between the two adjacent vibrator units 90 is half the wavelength of the vibrator unit electromagnetic waves, and in the M-column vibrator unit 90, the distance between the two adjacent vibrator units 90 is half the wavelength of the vibrator unit electromagnetic waves. In this way, the crests of the vibrator unit electromagnetic waves radiated by adjacent vibrator units 90 can meet, thereby enhancing the strength.
