Detailed Description

In order to make those skilled in the art better understand the technical solution of the present disclosure, the following describes the method for determining the antenna parameter and the antenna provided in the present disclosure in detail with reference to the accompanying drawings.

Example embodiments will be described more fully hereinafter with reference to the accompanying drawings, but which may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

Embodiments of the present disclosure and features of embodiments may be combined with each other without conflict.

As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and/or "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

For the terminal type with high-speed movement (the speed per hour is 800km/h to 1200km/h) of an airplane, the adoption of the cell coverage distance (usually within 5 km) of the conventional wireless communication system causes the cell switching to occur frequently, thereby causing the performance of the communication system to be reduced. In order to access the internet on an airplane, at least the cell coverage distance is required to exceed 100 km. This requirement has exceeded the coverage of terrestrial 3D multiple Input multiple Output (3D-MIMO, 3D MIMO Input multiple Output) antennas in the related art.

The civil aircraft altitude shown in figure 1 is 10km and in order to achieve a cell coverage radius of 300km it is necessary that the vertical dimension of the base station antenna covers a range of 2 ° to 90 °. The vertical dimension of the base station antenna is required to cover the entire 90 range, as further considerations for earth curvature and the like.

In the related art, in order to ensure the gain of the antenna (especially 3D-MIMO antenna), the coverage angle range in the vertical dimension is basically less than 60 ° (no signal is right above the base station), and the requirement of the open coverage wireless system cannot be met.

In view of this, as one aspect of the present disclosure, there is provided a parameter determining method of a 3D-MIMO antenna, as shown in fig. 1, the parameter determining method including:

in step S110, receiving a coverage requirement and parameters of each radiation element of a three-dimensional multiple-input multiple-output 3D-MIMO antenna;

in step S120, determining an angle of a radiation plane of each radiation element according to the coverage requirement and a parameter of each radiation element of the 3D-MIMO antenna, where an included angle exists between at least some radiation planes of the radiation elements and a vertical direction of the 3D-MIMO antenna.

A 3D-MIMO antenna typically comprises a plurality of radiating elements each having a radiating surface for transmitting or receiving signals. After the angles of the radiation surfaces of the radiation elements are determined, when the 3D-MIMO antenna is manufactured, each radiation element may be set according to the angle of the radiation surface of each radiation element determined in step S110, so that in the 3D-MIMO antenna, an included angle exists between at least part of the radiation surfaces of the radiation elements and the vertical direction of the 3D-MIMO antenna.

For the radiating array element, the signal intensity in the normal direction of the radiating surface is the largest, and the signal intensity in the tangential direction of the radiating surface is the weakest.

In the present disclosure, the type of coverage requirement is not particularly limited. The coverage requirements may include a coverage radius, a vertical dimension coverage angle, and the like.

In the application, an included angle exists between the radiation plane of at least part of the radiation array elements and the vertical dimension direction of the 3D-MIMO antenna, so that the normal direction of the part of the radiation array elements is different from the normal direction of other radiation array elements, the vertical dimension coverage angle of the 3D-MIMO antenna and the coverage border of the 3D-MIMO antenna can be improved, the coverage requirements of mobile communication networks such as air coverage or sea coverage can be met under the condition of not switching cells, and therefore users on vehicles (such as airplanes or ships) can be ensured to stably access the Internet.

In the method, the angle of the radiation surface of at least part of the radiation array elements is designed to supplement the electronic inclination angle of the radiation array elements, so that the vertical dimension coverage angle of the 3D-MIMO antenna can be enlarged.

In this disclosure, the parameters of the radiating elements used for determining the angles of the radiating elements are not particularly limited. For example, the parameters may include the number of radiating elements, the arrangement of each radiating element, the gain requirement of each radiating element, the beam width of the 3D-MIMO antenna, and the like.

In the present disclosure, the form of the received coverage requirement and the parameters of each radiating array element are not particularly limited. Coverage above the base station (i.e., empty coverage) can be represented by identifier 0001, and coverage below the base station (e.g., sea coverage) can be represented by identifier 0010. The parameters of the individual radiating elements can be represented by specific parameter values.

In the present disclosure, the specific structure of the 3D-MIMO antenna is not particularly limited. For example, the vertical dimension of the 3D-MIMO antenna includes N sub-arrays, each of which includes a plurality of the radiating elements arranged in the horizontal dimension.

For the coverage requirement of the empty coverage, the coverage requirement includes covering the upper part of the base station where the 3D-MIMO antenna is arranged, which requires that the vertical dimension coverage angle reaches a certain angle (for example, between 60 ° and 90 °), and when the vertical dimension coverage angle is at the angle, there is signal coverage in a certain range right above the base station.

Correspondingly, in step S120, an included angle between a radiation plane of a radiation array element of the first M sub-arrays from high to low in the vertical dimension of the 3D-MIMO antenna and the vertical dimension direction of the 3D-MIMO antenna is determined as being rotated counterclockwise by a first predetermined angle from the vertical dimension direction, where M and N are positive integers, N > 1, and M is greater than or equal to 1 and less than N.

In the related art, the coverage angle of the 3D-MIMO antenna in the vertical dimension does not exceed 60 °, resulting in no signal coverage right above the base station. In the present disclosure, after the radiation plane of the radiation array element on the top layer in the 3D-MIMO antenna is adjusted by rotating counterclockwise, the normal direction of the radiation array element can be tilted towards the sky. By adjusting the electronic inclination angle in a matching way, the coverage angle of the vertical dimension can be between 60 degrees and 90 degrees.

In the present disclosure, the specific structure of the 3D-MIMO antenna is not particularly limited. For example, as shown in fig. 2, N of the 3D-MIMO antenna is 4, and each of the sub-arrays includes 8 radiating elements.

In the 3D-MIMO antenna, each of the first layer radiating elements, the second layer radiating elements, the third layer radiating elements and the fourth layer radiating elements in the vertical direction (i.e., the vertical direction in fig. 3 and 4) is denoted by 100a, 100b, 100c and 100D, respectively. The radiation plane of the radiation array element 100a is Sa, the radiation plane of the radiation array element 100b is Sb, the radiation plane of the radiation array element 100c is Sc, and the radiation plane of the radiation array element 100d is Sd. Shown in fig. 3 is a 3D-MIMO antenna in the related art, in which the normal directions of the respective radiating elements are horizontal directions. In this case shown in fig. 3, the coverage angle of the 3D-MIMO antenna in the vertical dimension does not exceed 60 °.

If the vertical dimension coverage angle in the vertical dimension coverage requirement is between 80 ° and 90 °, then M may be selected to be 1 or 2, and the first predetermined angle α may be selected in a range of 40 ° to 50 ° in step S120.

In the present disclosure, the value of M may be selected according to specific requirements. The larger M is, the larger the number of beams generated by the 3D-MIMO antenna is, and the smaller M is, the smaller the number of beams generated by the 3D-MIMO antenna is.

Shown in fig. 4 is the case where M is 1 and the first predetermined angle α is 45 °. Specifically, the radiation plane Sa of the first layer of radiation array elements 100a in the vertical dimension is rotated by 45 ° counterclockwise from the vertical dimension. In this embodiment, the base station including the 3D-MIMO antenna has a 90 ° coverage angle in the vertical dimension, and the resulting signal covers both directly above the base station and into the space within a coverage radius of 300 km.

As shown in fig. 5, the 3D-MIMO antenna generates three beams of beam 1, beam 2, and beam 3, and can realize a cell having a coverage radius of 300 km. In addition, the wave beam 1 can cover the area right above the base station, so that the requirement that a civil aircraft with the flight height of 10km is accessed to the Internet can be met. Specifically, when the flying height of the airplane is 10km, the number is covered by a beam 1 right above a base station; when the horizontal distance between the aircraft and the base station is 2km to 10km, the aircraft is covered by a beam 2; the aircraft, flying to the horizontal distance between the base stations, is 10km to 300km, covered by the beam 3.

In the embodiment shown in fig. 6, M is 2, that is, the radiation surfaces of the radiation frame elements of the first two layers from top to bottom are determined to be rotated counterclockwise by the first predetermined angle α from the vertical dimension.

Specifically, in the vertical dimension, the radiation plane Sa of the first layer of radiation array elements 100a is rotated 45 ° counterclockwise from the vertical dimension, and the radiation plane Sb of the second layer of radiation array elements 100b is rotated 45 ° counterclockwise from the vertical dimension. In this embodiment, the coverage angle of the base station including the 3D-MIMO antenna in the vertical dimension is 90 °. As shown in fig. 7, the generated signal can cover the space with the coverage radius of 300km, as well as the space right above the base station. Specifically, when the flying height of the airplane is 10km, the number is covered by a beam 1 right above a base station; when the aircraft flies to the position with the horizontal distance of 2km to 10km from the base station, the aircraft is covered by the wave beam 2 and the wave beam 3; the aircraft, flying to the horizontal distance between the base stations, is 10km to 300km, covered by a beam 4.

As an alternative embodiment, the radiating elements are dual polarized radiating elements, so that the 3D-MIMO antenna is a 64-port 3D-MIMO antenna. In other words, the 3D-MIMO antenna ports are 4 ports in the vertical dimension (denoted by V), 8 ports in the horizontal dimension (denoted by H), and 2 ports resulting from dual polarization (denoted by P), and the total number of ports is 4(V) × 8(H) × 2(P) ═ 64. Of course, the 3D-MIMO antenna may be a 32-port 3D-MIMO antenna.

To achieve coverage of the sea signal, the base station is typically located on a mountain near the sea. In order to realize that there is also a signal directly below the base station, correspondingly, the coverage requirement includes covering the lower side of the base station where the 3D-MIMO antenna is disposed, so that the vertical dimension coverage angle of the 3D-MIMO antenna reaches a certain angle (for example, the vertical dimension coverage angle is between 60 ° and 90 °).

Correspondingly, in step S120, an included angle between a radiation plane of the radiation array element of the first M sub-arrays from low to high in the vertical dimension of the 3D-MIMO and the vertical direction is determined as clockwise rotating by a second predetermined angle from the vertical direction, where M and N are positive integers, N > 1, and M is greater than or equal to 1 and less than N.

The radiation surface of the radiation array element positioned on the lower layer in the 3D-MIMO antenna is adjusted to rotate clockwise from the vertical direction by a second preset angle, which is equivalent to that the radiation surface of the radiation array element inclines downwards, and the normal direction of the radiation surface of the radiation array element is closer to the position right below the base station, so that the vertical dimension coverage angle of the 3D-MIMO antenna can be improved.

Optionally, in the coverage requirement, the vertical dimension coverage angle is between 80 ° and 90 °, N is 8, M is 4, and the second predetermined angle is selected from a range of 40 ° to 50 °.

In the particular embodiment shown in fig. 8, the vertically-dimensional array of 3D-MIMO antennas comprises eight sub-arrays. Specifically, array elements in the top eight sub-arrays from bottom to top in the vertical dimension are denoted by 100h, 100g, 100f, 100e, 100d, 100c, 100b, 100a, respectively. The radiation plane of the radiation array element 100a is Sa, the radiation plane of the radiation array element 100b is Sb, the radiation plane of the radiation array element 100c is Sc, the radiation plane of the radiation array element 100d is Sd, the radiation plane of the radiation array element 100e is Se, the radiation plane of the radiation array element 100f is Sf, the radiation plane of the radiation array element 100g is 100g, and the radiation plane of the radiation array element 100h is 100 h.

The radiation planes of the radiation array elements of the four sub-arrays below (i.e. radiation plane Sa of radiation array element 100a, radiation plane Sb of radiation array element 100b, radiation plane Sc of radiation array element 100c, and radiation plane Sd of radiation array element 100 d) are rotated clockwise from the vertical dimension by a second predetermined angle β.

Applying the 3D-MIMO antenna provided in fig. 8 in the specific scenario shown in fig. 9, sea coverage in the vertical dimension of 90 ° can be achieved.

For ease of arrangement, further optionally, the second predetermined angle may be 45 °.

As mentioned above, besides determining the angle of the radiation plane of each radiation array element, the 90 ° coverage angle in the vertical dimension can be achieved by adjusting the electron tilt angle of the radiation array element at the same time.

In the present disclosure, how to determine the electron tilt angle of each radiating array element is not particularly limited. For example, after the radiation surface angle of each radiation array element is set, antenna simulation may be performed, the electronic tilt angle of each radiation array element may be adjusted through simulation, and when the vertical dimension coverage angle of 60 ° to 90 ° is achieved, the electronic tilt angle of each radiation array element may be stopped from being adjusted through simulation, and the electronic tilt angle at that time may be recorded.

Optionally, the electronic tilt angle of the radiating array element may be adjusted by adjusting the weight to form a beam and the capability of electrical tuning through a corresponding phase shifter of the radiating array element.
