These drawings and written description are not intended to limit the scope of the disclosed concepts in any way, but rather to illustrate the concepts of the disclosure to those skilled in the art by reference to specific embodiments.
Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The following explains an application scenario of the embodiment of the present application:
fig. 1 is a diagram of an application scenario of a luneberg lens antenna according to an embodiment of the present application, and as shown in fig. 1, the luneberg lens antenna according to the embodiment of the present application is installed as a base station antenna on a 5G base station, and the 5G base station is disposed near a high-speed rail and is used for providing 5G wireless signal coverage for a high-speed rail.
In the prior art, a plate antenna is a common antenna form in a communication network, and a plurality of antenna elements are adopted to amplify signals. The directional diagram of the plate-shaped antenna in the horizontal direction is of a sector symmetrical structure, and the gain is larger within a horizontal angle of +/-60 degrees; outside the direction of +/-60 degrees, the antenna gain is reduced by 10dB, the gain is lower, taking a linear coverage scene as an example, the maximum gain of the service beam of the 8TR antenna is in the direction of 0 degree right ahead, and reaches 21 dBi; however, as the beam shifts, the gain decreases rapidly, decreasing to 16-18dBi at the edge of coverage, the above-mentioned drawbacks of conventional patch antennas result in degradation of 5G signal quality at the edge of the sector coverage area.
Meanwhile, the horizontal beam width of the plate-shaped antenna is 65 degrees, so that no coverage exists in a region from 65 degrees to 90 degrees, and a signal blind spot phenomenon exists. The 5G network frequency is in a Sub6GHz frequency band, mainly a 3.5GHz frequency band and a 2.6GHz frequency band, and the wireless signal coverage capability is greatly reduced compared with the 1.8GHz frequency band and the 2.1GHz frequency band adopted by the existing 2/3/4G. The high-frequency characteristic of the 5G network causes the signal path loss to be serious, the coverage range of a single antenna of the plate-shaped antenna is small, the design is carried out according to the uplink rate of a 5G user of 200Mbps (theoretical value), the coverage radius of a 5G base station under a 3.5GHz frequency band is only 250 meters, and the base station density can meet the continuous coverage requirement only by increasing 3-4 times of the existing number. Taking a high-speed rail coverage scene as an example, because high-speed movement and carriage penetration loss are large, under the condition of a station distance of 500 meters, the user rate of a 5G network in a 3.5GHz frequency band can only reach 1-2 Mbps uplink and 50Mbps downlink, the use experience of the user using the 5G network can be seriously influenced, and the 5G base station is further encrypted, so that the construction cost of the base station is greatly increased, and huge economic pressure is brought to an operator.
The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
Fig. 2 is a schematic structural diagram of a luneberg lens antenna according to an embodiment of the present application, where the luneberg lens antenna includes:
the first luneberg lens 1 is a dielectric sphere, column or other geometric shapes with dielectric constants gradually changing from 2 to 1 from inside to outside, and the first luneberg lens 1 comprises an incident end 11 and an emergent end 12.
The first oscillator unit group 2 is provided with a plurality of oscillator units 21, the oscillator units 21 are arranged on one side of an incident end of the first luneberg lens 1 according to a first arrangement mode, and narrow beams with different powers are emitted to a target coverage area through the first luneberg lens 1 to form a first wide beam covering the target coverage area.
And the first distributor 3 is electrically connected with the plurality of oscillator units 21, and is used for feeding base station information sources with different powers into the plurality of oscillator units 21 so as to enable the first wide beam to form corresponding signal coverage strength at different positions of a target coverage area.
Illustratively, the first dipole unit group 2 emits a signal from the incident end 11 of the first luneberg lens 1, and after refraction inside the first luneberg lens 1, the signal is converged to form a narrow beam, and the narrow beam is emitted from the exit end 12 of the first luneberg lens 1, it should be noted that the narrow-band beam has a corresponding radiation angle, the magnitude of the radiation angle is related to the radius of the first luneberg lens 1 and the length of the dipole unit 21, and the larger the length of the dipole unit 21 is, the smaller the radius of the first luneberg lens 1 is, the larger the radiation angle of the correspondingly formed narrow beam is, i.e. the larger the beam width of the narrow beam is. After the narrow beam is emitted to the outside, the narrow beam is gradually attenuated along with the increase of the distance, and a region formed from the position of the luneberg lens antenna to the farthest effective coverage distance is the coverage region of the narrow beam.
Illustratively, the oscillator unit 21 is a cross-polarized combined oscillator, and an electromagnetic signal emitted by the oscillator unit 21 on the spherical surface of the first luneberg lens 1 is radiated to a certain area of the spherical surface, which is equivalent to a point source on the spherical surface.
The plurality of oscillator units 21 are arranged on the incident end 11 side of the first luneberg lens 1 according to a first arrangement mode, and the plurality of oscillator units 21 emit narrow beams with different powers to a target coverage area through the first luneberg lens 1. Illustratively, the first deployment mode includes: the oscillator units 21 with the preset first oscillator number are arranged on the surface of one side of the incident end 11 of the first luneberg lens 1 along the horizontal direction in a preset first emission angle sequence. Fig. 3 is a schematic diagram of one implementation of the arrangement of the vibrator units 21 in a first arrangement; fig. 4 is a schematic diagram of another implementation mode in which the vibrator units 21 are arranged in the first arrangement mode. Illustratively, the wireless signals emitted by each oscillator unit 21 are converged by the first luneberg lens 1 to form a narrow beam, and the narrow beam is emitted from the other side to the direction of the connection line between the oscillator unit 21 and the center of the first luneberg lens 1. Each vibrator unit 21 in the first vibrator unit group 2 covers a certain horizontal angle direction, the vibrator units 21 are separated by a certain angle, and the wave beams of the plurality of vibrator units 21 are overlapped to form a first wide wave beam corresponding to the first distribution mode, and the first wide wave beam is emitted to a target coverage area to realize high-gain and wide wave beam coverage. The first emission angle sequence is set according to a specific usage scenario, and is not limited herein.
Illustratively, the element unit 21 is an antenna base unit having a corresponding operating frequency bandwidth for transmitting and receiving wireless signals. The oscillator unit 21 and the first luneberg lens 1 form a narrow-beam high-gain antenna, the maximum gain direction of the antenna is in the connecting line direction of the oscillator unit 21 and the center of the first luneberg lens 1, and the beam width is related to the working frequency, the size of the oscillator unit 21, the size of the first luneberg lens 1 and the like
The plurality of oscillator units 21 are arranged at different positions on one side of the incident end 11 according to a first arrangement mode, the plurality of oscillator units 21 emit electromagnetic signals, the electromagnetic signals are refracted by the first luneberg lens 1 and then radiated in different directions to generate different narrow beams, and for example, if the plurality of oscillator units 21 have the same size, the radiation angles of the narrow beams generated by the plurality of oscillator units 21 are the same correspondingly; on the contrary, if the sizes of the plurality of transducer elements 21 are different, the radiation angles of the narrow-band beams generated by the respective plurality of transducer elements 21 are different and the same. The method comprises the steps that a plurality of vibrators separated by a certain angle form corresponding narrow beams to radiate to the outside, then first wide beams are synthesized, and for a linear coverage scene, linear coverage areas corresponding to the first wide beams are target coverage areas.
As shown in fig. 3 and 4, as the target coverage area of the first wide beam emitted by the first element unit group 2 is closer to the coverage edge, the corresponding area is farther from the position of the first luneberg lens antenna, and accordingly, the attenuation of the wireless signal is more serious. In order to overcome the problem of low signal gain at the coverage edge, the first distributor 3 feeds base station information sources with different powers to the plurality of oscillator units 21, so that the first wide beam emitted by the first oscillator unit group 2 forms corresponding signal gains at different positions of the target coverage area, for example, the signal gain is larger the farther the distance is. Illustratively, the first distributor 3 may be a feeding network, including a transmission and distribution system of one or more wireless signals, which distributes and feeds the base station source power to each element unit 21 in the first element unit group 2. The feed network controls the distribution proportion of the power of the signal fed into each oscillator unit 21, thereby controlling the signal intensity in the corresponding direction and angle range, realizing the shaping of the horizontal directional diagram of the antenna and meeting the requirement of strong and weak coverage of the signal in a target area. The oscillator units 21 and the oscillator units 21 emit different electromagnetic wave powers, and illustratively, the longer the distance of each oscillator unit 21 from the target coverage area 8 corresponding to each oscillator unit 21 to the target coverage area, the higher the corresponding emission power, so as to make the signal intensity coverage uniform in the whole linear coverage area.
Illustratively, the wide beam corresponds to a wireless signal frequency in the Sub6GHz band.
Fig. 5 is a wide beam pattern of the luneberg lens antenna according to the embodiment of the present application, as shown in fig. 5, in a frequency band of 3.5GHz, a first wide beam emitted by the first dipole unit group 2 has different signal gains at different angles, so that corresponding signal gains are formed at different positions of a target coverage area, for example, a maximum gain of a wireless signal corresponding to an oscillator unit at the edge of the first dipole unit group 2 may reach 24.8dBi, thereby effectively improving signal coverage strength at the edge of the target coverage area.
In the embodiment, a luneberg lens antenna is provided, which includes a first oscillator unit group 2, where the first oscillator unit group 2 includes a plurality of oscillator units 21, the plurality of oscillator units 21 are disposed on one side of an incident end 11 of a first luneberg lens 1 according to a first arrangement manner, and narrow beams with different powers are emitted to a target coverage area through the first luneberg lens 1 to form a first wide beam covering the target coverage area; and the first distributor 3 is electrically connected with the plurality of oscillator units 21, and is used for feeding base station information sources with different powers into the plurality of oscillator units 21 so as to enable the first wide beam to form corresponding signal coverage strength at different positions of a target coverage area. The wide beam emitted to the target coverage area by the luneberg lens antenna can form corresponding signal coverage strength at different positions of the target coverage area, so that corresponding signal gain is obtained at different positions of the target coverage area, the uniformity of signal strength coverage is improved, the coverage efficiency of 5G wireless signals is improved, and the network construction cost is reduced.

Illustratively, the power of the base station source fed by the first distributor 3 to the plurality of element units 21 is positively correlated with the first coverage distance. When the first coverage distance is farther, that is, the distance between the base station and the sub coverage area is farther, the power of the base station information source fed by the first distributor 3 to the corresponding oscillator unit 21 is larger, and conversely, the distance between the base station and the sub coverage area is closer, the power of the base station information source fed by the first distributor 3 to the corresponding oscillator unit 21 is smaller, so as to achieve the purposes of large far-end signal gain and small near-end signal gain in the target coverage area.

By adjusting the phase of the oscillator unit 21, the electromagnetic wave signals with different phases can be prevented from interfering with each other, and the quality of wireless signals can be prevented from being influenced.
