Referring to fig. 1 to 2, schematic structural diagrams of an antenna according to an embodiment of the present invention are provided, where the antenna includes a first array 1100 and a second array 1200, the first array 1100 is rotatably connected to a side of the second array 1200, and exemplarily, the first array 1100 is rotatably connected to a top of the second array 1200. Specifically, the first array 1100 may be rotatably coupled to the top of the second array 1200 by a rotating shaft, and the first array 1100 may be driven to rotate by a motor. The motor can move with the driving rotating shaft through a transmission part, and the transmission part can be a connecting rod and the like.
The first array 1100 may include a plurality of first oscillator units 1110, the plurality of first oscillator units 1110 are arranged in an array, a single first oscillator unit 1110 includes at least one radiation unit 1111 in a vertical plane, for example, the first oscillator unit 1110 provided in the embodiment of the present invention includes two vertically arranged radiation units 1111, and the plurality of first oscillator units 1110 are horizontally arranged in a row, based on which the first array 1100 has one degree of freedom. Of course, it can be understood by those skilled in the art that the number of the radiation units 1111 of each first oscillator unit 1110 is not limited to two, and the first oscillator units 1110 may be arranged according to actual requirements, and the embodiment of the present invention is merely an exemplary illustration.
The second array 1200 may include a plurality of second oscillator units 1210, the plurality of second oscillator units 1210 are arranged in an array, a single second oscillator unit 1210 includes at least one radiation unit 1111 in a vertical plane, for example, the second oscillator unit 1210 provided in the embodiment of the present invention includes four radiation units 1111 vertically arranged, and the plurality of second oscillator units 1210 are horizontally arranged in three rows, based on which the second array 1200 has three degrees of freedom. Of course, it can be understood by those skilled in the art that the number of the radiation units 1111 of each second oscillator unit 1210 is not limited to four, and the arrangement may be performed according to actual requirements, and the embodiment of the present invention is merely an exemplary illustration.
Illustratively, the row spacing of the radiation elements 1111 may be 0.6 to 0.8 operating frequency wavelengths, and the column spacing may be 0.4 to 0.6 operating frequency wavelengths.
Referring to fig. 3, taking the first array 1100 as an example, each first oscillator unit 1110 is connected to a corresponding radio frequency port, and performs radio frequency signal processing and digital-to-analog conversion by using the radio frequency processing unit TRX, and finally performs weighting adjustment by using the baseband processing unit, so that the level value or the phase weight of the first oscillator unit 1110 changes, so that the main beam of the directional diagram is aligned with the signal direction, the zero point direction is aligned with the interference direction, and dynamic beam scanning of the first array 1100 is realized, thereby realizing a beam adaptive tracking function. The second vibrator units 1210 are similar, and each second vibrator unit 1210 is connected to a corresponding radio frequency port, which is not described herein again.
Because the first array 1100 is rotatably connected to the side surface of the second array 1200, the direction of the first array 1100 can be changed according to the position of the terminal, so that the first array can keep facing the terminal, the signal coverage blind area of the base station can be supplemented, and the signal coverage range of the base station can be enlarged.
Referring to fig. 4, based on the antennas shown in fig. 1 to 2, an embodiment of the present invention provides a ground-air communication control method applied to a base station, where the base station is provided with the antennas shown in fig. 1 to 2, where the ground-air communication control method includes, but is not limited to, the following steps 401 to 403:
step 401: acquiring the position of a terminal;
in step 401, acquiring the location of the terminal may be regarded as acquiring a real-time location of the aircraft, for example, longitude and latitude information of the terminal may be acquired through a global positioning system GPS, a beidou positioning system, and the like, so as to confirm the location of the terminal. The terminal may be a communication device of the airplane itself, or may be a mobile terminal used in the airplane, or the like.
Step 402: controlling the first array to rotate so that the first array changes the orientation according to the position of the terminal;
in step 402, the first array is controlled to rotate so that the first array changes its orientation according to the position of the terminal, that is, the first array keeps facing the terminal by controlling the first array to rotate, so that the terminal can receive the beam transmitted by the first array.
Step 403: the antenna is controlled to transmit communication signals to the terminal.
Because the first array is rotationally connected to the side face of the second array, the orientation of the first array is changed according to the position of the terminal by acquiring the position of the terminal, so that the first array can keep facing the terminal, the signal coverage blind area of the base station is supplemented, and the signal coverage range of the base station can be enlarged.
In an embodiment, the step 402 of controlling the first array to rotate so that the first array changes its orientation according to the position of the terminal may specifically include:
when the distance between the terminal and the antenna is smaller than or equal to a first distance threshold value, the first array is controlled to rotate so that the first array faces the terminal, and the inclination angles of the first array and the second array relative to the ground are different.
And when the distance between the terminal and the antenna is larger than a first distance threshold value, controlling the first array to rotate so that the inclination angles of the first array and the second array relative to the ground are the same.
For the sake of brevity, the inclination angle of the first array or the second array with respect to the ground will be described below simply as the inclination angle of the first array or the second array.
Based on the traditional two-dimensional plate-shaped directional antenna, when an airplane flies to the headspace range of the antenna, because the inclination angle of the antenna is fixed, the terminal on the airplane cannot receive the wave beam sent by the antenna, and therefore the communication between the terminal and the antenna is influenced. Therefore, when the distance between the terminal and the antenna is smaller than or equal to the first distance threshold, the first array is controlled to rotate to enable the first array to face the terminal, so that the terminal can receive the beam sent by the first array, at the moment, the inclination angles of the first array and the second array are different, the first array can cover the headspace range of the antenna, the second array keeps covering the original range of the antenna, and the signal coverage range of the antenna is increased.
When the distance between the terminal and the antenna is larger than the first distance threshold value, the terminal leaves the headspace range of the antenna at the moment, the first array is controlled to rotate so that the inclination angles of the first array and the second array are the same, namely the first array and the second array are coplanar, therefore, the first array and the second array can simultaneously emit beams to the terminal, the total power of the antenna is improved, and the coverage capability of the antenna is improved.
It can be understood that the first distance threshold may be set according to an actual situation, for example, the first distance threshold may be set to 100 kilometers, 90 kilometers, or 80 kilometers, and the like, and the embodiment of the present invention does not limit a specific value of the first distance threshold, as long as it can be determined that the terminal enters the headspace range of the antenna through the first distance threshold, and those skilled in the art can understand that the first distance threshold may be determined by combining an actual height of the terminal and a fixed inclination angle of the antenna, for example, when the actual height of the terminal becomes higher, a distance between the terminal and the antenna may also increase, and the first distance threshold may be adjusted accordingly; for example, when the tilt angle of the antenna is increased, the headspace area which cannot be covered by the antenna is correspondingly reduced, and the first distance threshold may be adjusted accordingly.
Therefore, the first array is controlled to rotate according to the distance between the terminal and the antenna, so that the coverage area of the antenna can be increased, the antenna can cover the headspace range, and the power of the antenna in the non-headspace range can be increased.
In an embodiment, when the distance between the terminal and the antenna is less than or equal to the first distance threshold, that is, the terminal is located in the headspace of the antenna at this time, in step 403, the antenna is controlled to send the communication signal to the terminal, and only the first array is controlled to send the communication signal to the terminal, so that the effect of supplementing the signal blind area in the headspace range of the antenna is achieved, and the overall power consumption of the antenna is reduced.
In an embodiment, when the distance between the terminal and the antenna is greater than the first distance threshold, that is, the terminal leaves the headspace range of the antenna, the antenna is controlled to transmit the communication signal to the terminal, which may be further refined into a plurality of ways:
in an embodiment, when the distance between the terminal and the antenna is greater than the first distance threshold and less than or equal to the second distance threshold, where the second distance threshold is greater than the first distance threshold, that is, the terminal just leaves the headspace range of the antenna, only the second array is controlled to transmit the communication signal to the terminal, that is, the first array does not transmit the communication signal to the terminal, so that smooth switching of beams can be ensured. It is understood that the second distance threshold is greater than the first distance threshold.
In an embodiment, when the distance between the terminal and the antenna is greater than the second distance threshold, that is, the distance between the terminal and the antenna is farther and farther, the first array and the second array are simultaneously controlled to transmit communication signals to the terminal, so as to increase the power of the antenna and increase the gain of the beam.
It can be understood that the second distance threshold may be set according to actual situations, for example, the second distance threshold may be set to 200 kilometers, and the specific value of the second distance threshold is not limited in the embodiment of the present invention.
It will be appreciated that the above-described control of the first array, or the transmission of communication signals to the terminals for the second array, may be the adjustment of the phase weights of the element units, so that the antenna generates the appropriate beam. When the distance between the terminal and the antenna is changed, the self-adaptive tracking of the wave beam of the antenna can be realized by adjusting the phase weight of the oscillator unit. Illustratively, when the distance between the terminal and the antenna is changed from 300 km to 200 km, the shape of the beam can be changed by adjusting the phase weights of the element units.
Based on the ground-air communication control method, the antenna provided by the embodiment of the invention can adaptively track the terminal, and can maximally realize the coverage of 2-90-degree vertical-dimension space signals.
The principle of the ground-air communication control method according to the embodiment of the present invention is described as a practical example.
Referring to fig. 5, the element units of the antenna vertical plane may be divided into four groups in the vertical dimension, wherein the first array 1100 has one group of first element units 1110 having one degree of freedom; the second array 1200 has three sets of second vibrator units 1210 with three degrees of freedom. According to the distance between the terminal and the antenna (namely different positions of the terminal), different degrees of freedom are selected for forming the synthetic beam, so that the antenna covers different positions in the air, the frequency spectrum utilization rate can be effectively improved, a selection space for distributing more resources can be provided for the system, and more capacity gains can be obtained.
The specific control mode is as follows:
the position 1 is a point (for example, 300 kilometers) at which the terminal is farthest from a ground base station, the direct-view path is dominant, the angle of the first array 1100 is set to be consistent with that of the second array 1200, and a high-gain narrow beam is synthesized by performing beam forming operation on the first vibrator unit 1110 and the second vibrator unit 1210 with four degrees of freedom in total on the vertical plane, so that the waveform of a transmitted signal has certain directivity, and the beam 1 is directed to the empty farthest point;
position 2 is the terminal distance from the ground base station second distance point (for example, 200 km), when the terminal flies from position 1 to position 2, the angle of the first array 1100 is still consistent with that of the second array 1200, and the beam 2 is directed to position 2 by adjusting the phase weights of the first oscillator unit 1110 and the second oscillator unit 1210 with four degrees of freedom in total on the vertical plane, so that the main beam of the antenna can adaptively track the arrival direction of the main signal of the terminal;
the position 3 is a point (for example, 100 km) where the terminal is closer to the ground base station, when the terminal flies from the position 2 to the position 3, in order to ensure smooth switching of the beam, the antenna selection technology is adopted, the radio frequency port is controlled by controlling the radio frequency processing unit TRX, the phase of the second oscillator unit 1210 which only has three degrees of freedom in the vertical plane of the second array 1200 is selected to be adjusted, and each first oscillator unit 1110 of the first array 1100 is not excited, so that the beam 3 points to the position 3;
position 4 is in ground base station headspace scope, and when the terminal flies to position 4 by position 3, the antenna beam will be difficult to realize anticipated coverage effect, drives the rotation of pivot through transmission, adjusts the inclination of first array 1100, sets up first array 1100 to the tilt up to only excite through first oscillator unit 1110 of a degree of freedom in the first array 1100 vertical plane, make beam 4 point to position 4, realize carrying out the benefit blind filling of signal to antenna headspace scope, with the signal coverage of expansion antenna.
It should be added that the specific distance values between the position 1 to the position 4 and the antenna are only illustrative, and may be adjusted according to specific situations in practical applications.
The beam forming principle provided by the embodiment of the invention is as follows:
referring to fig. 5, where the radius of the cell covered by the antenna is R, the flying height of the terminal is H, and the beam azimuth α is:
because the direction of the wave beam is adjusted according to the radius of the cell on the basis that the upward elevation angle of the antenna is fixed, the upward elevation angle of the antenna needs to be determined firstly, and because the vertical scanning angle range of the digital wave beam is limited by the oscillator unit, if the adjusted digital wave beam is ensured to be in the vertical scanning range, the upward elevation angle of the antenna needs to be set according to the maximum cell radius, and at the moment, when the cell radius is reduced, the digital wave beam can be effectively adjusted to point, and the coverage of the cell is ensured not to cross the border.
Assuming that the cell radius is at most RmaxThe method is characterized in that, as shown in (1),
at the moment, the antenna is fixed at the upper elevation angle
VBWL-A,3dBRepresents the vertical 3dB lobe width of the (Lower Antenna) second array 1200;
accordingly, three vertically-oriented beams VT2, VT0 and VT1 can be designed to meet the coverage requirement when the cell is far away from the terminal, and according to the vertical beam synthesis principle, the orientations T1 and T2 of the beams can be set as follows:
when the radius of the cell is R (R < R)max) When it is used, the method is shown in (1)
α＞αmin,
At this time, can maintain
The change is not changed;
dynamically reducing T1 to T1,c＝round[-T2-(α-αmin)]。
In addition, referring to fig. 6, another antenna is provided according to an embodiment of the present invention, which is different from the antenna shown in fig. 1 in that the first array 1100 includes at least two independent array bodies, and the at least two array bodies are respectively rotatably connected to the side surfaces of the second array 1200. Illustratively, the first array 1100 includes two array bodies, specifically, the first array 1100 includes an array body a and an array body B, which are respectively rotatably connected to the top of the second array 1200, i.e., the array body a and the array body B can be rotated separately.
Based on the antenna structure shown in fig. 6, the ground-to-air communication control method provided in the embodiment of the present invention may be further refined, where in the step 402, the controlling the first array 1100 to rotate so that the first array 1100 changes the orientation according to the position of the terminal may specifically include: the rotation of the partial array bodies of the first array 1100 is controlled so that the partial array bodies change their orientation according to the position where the terminal is located.
For example, based on the antenna coverage diagram shown in fig. 5, when the terminal flies from position 3 to position 4, the antenna beam will not easily achieve the desired coverage effect, and the rotation of the rotating shaft is driven by the transmission device to adjust the tilt angle of the first array 1100, and the first array 1100 is set to tilt up, and then adjusting the tilt angle of the first array 1100 may be only adjusting the tilt angle of the array body a, and the array body B keeps the same tilt angle as the second array 1200, but of course, it can be understood that only adjusting the tilt angle of the array body B and the array body a keeps the same tilt angle as the second array 1200. By controlling only part of the array bodies of the first array 1100 to rotate according to the position of the terminal, when the uncovered area of the antenna headspace range is small, the blind-complementing coverage effect of the antenna headspace range can be realized, and the part of the array bodies, which have the same inclination angle as the second array 1200, in the first array 1100 can be shaped together with the second array 1200 to ensure the signal coverage strength outside the antenna headspace range, so that the flexibility of the antenna coverage is improved as a whole.
It is to be understood that, based on the antenna shown in fig. 6, the first array 1100 is equally divided into the array body a and the array body B, in other embodiments, the first array 1100 may also be unevenly divided into the array body a and the array body B, for example, the array body a and the array body B shown in fig. 6 each include four groups of first element units 1110, in other embodiments, the array body a may also include three groups of first element units 1110, and the array body B includes five groups of first element units 1110, and the specific division rule may be determined according to actual needs, and is not limited in the embodiments of the present invention.
It is to be understood that the first array 1100 is not limited to be divided into the array body a and the array body B, that is, the number of the array bodies of the first array 1100 is not limited to two, and may also be three, for example, the first array 1100 may also be divided into the array body a, the array body B, and the array body C, of course, the number of the array bodies of the first array 1100 may also be four, five, etc., the specific number may be determined according to actual requirements, and the embodiment of the present invention is not limited thereto.
It is understood that, when the number of the array bodies of the first array 1100 is multiple, the number of the array bodies of the first array 1100 is three as an example, that is, the first array 1100 includes the array body a, the array body B, and the array body C, based on the antenna coverage schematic diagram shown in fig. 5, when the terminal flies from the position 3 to the position 4, only one array body in the first array 1100 may be controlled to rotate, for example, only the array body a may be controlled to rotate, or two array bodies in the first array 1100 may be controlled to rotate, for example, the array body a and the array body B may be controlled to rotate, and a specific control manner may be determined according to actual needs, which is not limited by the embodiments of the present invention.
In addition, an embodiment of the present invention further provides a base station, including the antenna in the foregoing embodiment, so that the base station provided in the embodiment of the present invention obtains the location of the terminal, and changes the orientation of the first array according to the location of the terminal, so that the first array can keep facing the terminal, thereby implementing supplementation of the signal coverage blind area of the base station, and thus being capable of expanding the signal coverage area of the base station.
