[0003] In addition, the height of the base station antenna on the tower in the related technology is higher than the nearby scatterers (such as buildings, trees, etc.), but the position of the terminal (such as a mobile station) is lower, lower than the surrounding scatterers, so there is usually a non-line-of-sight (NLOS) wireless propagation link between the base station and the mobile station; there is multipath fading in the non-line-of-sight wireless propagation link, and the base station antenna usually adopts a positive and negative 45° polarization scheme to achieve polarization diversity to resist this fading; but in low-altitude application scenarios, there are no obstacles between the aerial antenna and the terminal (such as a drone), which is a line-of-sight (LOS) wireless link, and the base station antenna in the above-mentioned related technology cannot meet the coverage effect in the low-altitude application scenario.

[0026] like Figure 1 as well as Figure 2As shown, the present application provides a vibrator unit, and an embodiment of the vibrator unit of the present application includes: 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 the second plane, the second vibrator 20 and the projection of the first vibrator 10 in the second plane are cross-arranged, 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 the third plane, and the third direction c forms an angle of 45° 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 parallel to each other, and the first plane and the second plane are spaced apart.

[0027] By applying the technical solution of this 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 arranged to cross the projection of the first vibrator 10 in the second plane, the first direction a and the second direction b are perpendicular to each other, and the first vibrator 10 and the second vibrator 20 can radiate horizontally polarized and vertically polarized electromagnetic waves or circularly polarized electromagnetic waves by modulating the characteristics of the electromagnetic waves radiated by the first vibrator 10 and the second vibrator 20 (for example, the frequency, amplitude, phase difference, etc. of the radiated waves), the third vibrator 30 extends along the third direction c and is located in the third plane, and the third direction c is perpendicular to the first direction a and the second direction b. A 45° angle is formed, the third vibrator 30 can radiate electromagnetic waves with positive 45° polarization, the fourth vibrator 40 extends along the fourth direction d and is located in the fourth plane, the fourth direction d is perpendicular to the third direction c, and the fourth vibrator 40 can radiate electromagnetic waves with negative 45° polarization. The first vibrator 10, the second vibrator 20, the third vibrator 30 and the fourth vibrator 40 set as above can radiate electromagnetic waves with multiple polarizations, so that the vibrator unit can meet the coverage effect required in the low-altitude application scenario; in addition, multiple vibrators are reasonably arranged in one vibrator unit, so that the size of the vibrator unit is small while meeting the radiation of electromagnetic waves with multiple polarizations, thereby effectively saving tower resources. Therefore, the technical solution of this embodiment can effectively solve the problem that the vibrator unit in the related art is difficult to balance stable transmission and miniaturization.

[0028] It should be noted that in this embodiment, the second plane, the third plane and the fourth plane are coplanar, and in other embodiments, the second plane, the third plane and the fourth plane may be spaced apart from each other, or two of them may be spaced apart from each other.

[0029] In addition, in this embodiment, Figure 1As shown, the vibrator unit 90 also includes an excitation structure 50, which is electrically connected to the first vibrator 10 and the second vibrator 20 so that the first vibrator 10 can radiate a first electromagnetic wave and the second vibrator 20 can radiate a second electromagnetic wave, wherein the first electromagnetic wave and the second electromagnetic wave have the same frequency and a phase difference of +90° or -90°.

[0030] Such an arrangement enables the first vibrator 10 and the second vibrator 20 to cooperate to radiate circularly polarized electromagnetic waves. Specifically, the first vibrator 10 and the second vibrator 20 both have a feeding port, and the excitation structure 50 includes a bridge, which is used to feed the feeding port of the first vibrator 10 and the feeding port of the second vibrator 20; the bridge has two input ports and two output ports, wherein the two output ports are electrically connected to the feeding port of the first vibrator 10 and the feeding port of the second vibrator 20 respectively; when current is fed into one input port of the bridge, the two output ports generate currents with a phase difference of 90°, at which time the current on the feeding port of the second vibrator 20 is 90° ahead of the current on the feeding port of the first vibrator 10, and the feeding current has an amplitude of When the amplitude of the first and second electromagnetic waves are the same and the phase difference is 90° (that is, the frequency of the first electromagnetic wave and the second electromagnetic wave are the same and the phase difference is +90°), the first vibrator 10 and the second vibrator 20 can radiate left-hand circularly polarized electromagnetic waves; similarly, when 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 feeding port of the second vibrator 20 lags behind the current on the feeding port of the first vibrator 10 by -90°. When the feeding current is the same in amplitude and the phase difference is -90°, that is, the frequency of the first and second electromagnetic waves are the same and the phase difference is -90°), the first vibrator 10 and the second vibrator 20 can radiate right-hand circularly polarized electromagnetic waves. In addition, the feeding port of the second vibrator 20 is stimulated so that the second vibrator 20 can radiate vertically polarized electromagnetic waves; the feeding port of the first vibrator 10 is stimulated so that the first vibrator 10 can radiate horizontally polarized electromagnetic waves.

[0031] Therefore, by applying the vibrator unit 90 of this embodiment, the vibrator unit 90 can radiate electromagnetic waves with positive 45° polarization, negative 45° polarization, vertical polarization and horizontal polarization, and can also radiate electromagnetic waves with positive 45° polarization, negative 45° polarization, left-hand circular polarization and right-hand circular polarization.

[0032] like Figure 1As shown, the first vibrator 10 and the second vibrator 20 have an intersection, and the distance between the third vibrator 30 and the intersection is equal to the distance between the fourth vibrator 40 and the intersection. It should be noted that "the first vibrator 10 and the second vibrator 20 have an intersection" refers to the intersection generated by the intersection of the projection of the first vibrator 10 on the second plane and the second vibrator 20. This arrangement allows 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 to coincide with the intersection, and further allows the center of the electromagnetic wave synthesized by the four to be located at the center of the first vibrator 10 and the second vibrator 20 (that is, the intersection).

[0033] like 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 the present 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 to say, 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, the first vibrator group and the second vibrator group form a quasi-square structure, the geometric center of the quasi-square structure coincides with the intersection, and the feeding port of the third vibrator 30 and the feeding port of the fifth vibrator 60 are simultaneously excited, so that the first vibrator group can radiate electromagnetic waves with positive 45° polarization, and the feeding port of the fourth vibrator 40 and the feeding port of the sixth vibrator 70 are simultaneously excited, so that the second vibrator group can radiate electromagnetic waves with 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] like Figure 1 As shown, in this embodiment, the distance between the third vibrator 30 and the intersection is equal to the distance between the fifth vibrator 60 and the intersection. Specifically, the arrangement is such that the center of the electromagnetic wave generated by the first vibrator group is located at the intersection; the fourth vibrator 40 and the sixth vibrator 70 are arranged in the same manner.

[0036] like Figure 1As shown, in this embodiment, the distance between the third vibrator 30 and the fifth vibrator 60 is half the wavelength of the third electromagnetic wave. This arrangement enables the peak of the third electromagnetic wave and the peak of the fifth electromagnetic wave to meet at the intersection, thereby achieving the effect of electromagnetic waves superimposing each other, 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 the same manner.

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

[0038] like Figure 2 As shown, the second plane is located between the reflector 80 and the first plane, and the distance between the second plane and the reflector 80 is half the wavelength of the first electromagnetic wave. In this embodiment, since the distances between the first vibrator group, the second vibrator group, and the second vibrator 20 and the reflector 80 are equal and half the wavelength of the electromagnetic waves radiated by each, and the frequency and amplitude of the electromagnetic waves radiated by each vibrator are the same, the partial components of the electromagnetic waves radiated by the vibrators reflected by the reflector 80 and other components meet at the vibrators, thereby enhancing the intensity.

[0039] The present application also provides an antenna structure, which includes a vibrator unit, wherein the vibrator unit is the above-mentioned vibrator unit. The above-mentioned vibrator unit can effectively solve the problem that the vibrator unit in the related art is difficult to balance stable transmission and miniaturization, and the antenna structure with the above-mentioned vibrator unit also has the above-mentioned advantages.

[0040] like Figure 3As shown, there are multiple vibrator units 90, and the multiple vibrator units 90 are arranged in an array in the form of N rows * M columns, where N and M are both positive integers greater than 0. The setting of multiple vibrator units 90 can enhance the intensity of the electromagnetic waves radiated by the antenna structure and make the synthesized electromagnetic waves more uniform. In addition, such a setting enables the multiple vibrator units 90 to form MIMO (MIMO is the abbreviation of Multiple Input Multiple Output, which refers to multiple input multiple output technology. In the field of communications, MIMO technology is a technology that uses multiple antennas to transmit and receive signals to improve the data transmission rate and signal coverage of the communication system. By using multiple antennas to send and receive signals simultaneously, MIMO technology can significantly improve the performance and reliability of the communication system). Compared with the antenna structure in the related art, under the same required number of ports, the area of ​​the antenna structure is reduced by half, and the miniaturization effect of the antenna structure is significant.

[0041] like Figure 3 As shown, the vibrator unit 90 can radiate the vibrator unit electromagnetic wave, and in the N rows of vibrator units 90, the distance between two adjacent vibrator units 90 is half the wavelength of the vibrator unit electromagnetic wave, and in the M columns of vibrator units 90, the distance between two adjacent vibrator units 90 is half the wavelength of the vibrator unit electromagnetic wave. This arrangement allows the peaks of the vibrator unit electromagnetic waves radiated by adjacent vibrator units 90 to meet, thereby enhancing the intensity.

[0042] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0043] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0044] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
