The antenna system comprises at least three antennas, base lines of the at least three antennas are arranged in a non-collinear mode in the horizontal direction, signal input ends of the antennas are respectively connected with a transceiving component, and the transceiving component is suitable for adjusting the amplitude and/or the phase of the antennas so as to reconstruct and/or track wave beams of the antenna system.
Specifically, as shown in fig. 1, the antenna system of the present embodiment may include three antennas 1, 2, and 3, or may include four antennas 1, 2, 3, and 4 as shown in fig. 2, and of course, may further include more antennas. It should be noted that the small triangle and the small quadrangle at each vertex in fig. 1 and 2 are only schematic and do not represent the actual cross-sectional shape of the antenna, and each of fig. 1 and 2 corresponds to a view angle on a horizontal plane, in other words, the vertices of the triangle and the quadrangle in the figures correspond to the projection points of the base line of the antenna on the horizontal plane, and the physical structure of the antenna usually extends along the direction perpendicular to the view direction.
Fig. 1 and 2 show a triangle and a quadrangle, respectively, in which the base lines of the antennas are not collinear in the horizontal direction, and if more antennas are included, a pentagon, a hexagon or more polygons are formed, respectively, and the polygons may be in a standard pattern, such as an equilateral triangle, or in a non-standard pattern, such as a triangle in which three sides are not equal.
As shown in fig. 3, the antenna system of the present embodiment includes a plurality of antennas, i.e., an antenna 1, an antenna 2 to an antenna n, and a signal input terminal of each antenna is connected to a transceiver module, or a T/r (transmitter and receiver) module. Wherein each transceiving component is adapted to adjust the amplitude and/or phase of the corresponding antenna to enable reconstruction and/or tracking of the beam of the entire antenna system.
In this embodiment, a multi-baseline antenna system is formed by a plurality of antennas, the baselines of the antennas are not arranged in a collinear manner in the horizontal direction, and each antenna can have the same size, for example, all antennas are the same omnidirectional antenna, so that the coverage range can be ensured to be relatively comprehensive.
Optionally, as shown in fig. 3, the antenna system further includes radio frequency power amplifiers, where the radio frequency power amplifiers are respectively connected to the signal input ends of the transceiver modules.
Specifically, the rf power amplifier accesses the rf signal, and then is respectively connected to each transceiver component, or T/R component, and each transceiver component adjusts the amplitude and/or phase of the corresponding antenna according to the actual requirement, so as to reconstruct and/or track the beam of the whole antenna system.
Optionally, projection points of base lines of at least three antennas on a horizontal plane are suitable for connecting polygons with the number of combined sides being greater than or equal to three.
Specifically, as shown in fig. 1 and fig. 2, the vertices of the triangle and the quadrangle can be regarded as projection points of the base line on the horizontal plane, in other words, the horizontal connecting lines of two adjacent antennas are not overlapped with the horizontal connecting lines of the other two adjacent antennas, but form a polygon with more than three sides.
Optionally, the polygon is a rectangle.
Specifically, because gateway equipment such as routers mainly is the rectangle, set up antenna system into the many baselines antenna system that is the rectangle, help antenna system to install in gateway equipment, accomplish the reasonable application in space to correspondingly reduce the processing degree of difficulty.
Optionally, the antenna is an omni-directional antenna.
Specifically, each antenna is an omnidirectional antenna, and the physical dimensions of each antenna can be completely consistent, so that each antenna does not need to be set differently, requirements lower than those in the prior art are provided for the specific directivity and the processing difficulty of the antenna, and the preparation and the use of the antenna system of the embodiment are facilitated.
Optionally, the power adjustable range of the antenna is 0 to 100%, and the phase adjustable range of the antenna is 0 to 360 °.
The power of the antenna is positively correlated with the amplitude, the amplitude can be correspondingly adjusted by adjusting the power, and all the amplitudes needing to be used can be covered because the adjustable range of the power is 0-100%. Accordingly, all phases that need to be used can also be covered. Therefore, the whole antenna system of the embodiment can be adjusted at will to realize beam reconstruction and beam tracking on users in any area, thereby maintaining high-quality network signal coverage of the users.
Optionally, the reference points of a plurality of said antennas are arranged coplanar.
Optionally, a plurality of the antennas are integrally provided.
Specifically, the physical dimension of each antenna, viewed in the vertical direction, corresponds to the direction perpendicular to the views presented in fig. 1 and 2, in which the physical dimension of each antenna can extend, but the starting point, i.e. the reference point, of each antenna extension is coplanar, which enables all antennas to be processed on the same PCB (Printed Circuit Board), i.e. the antennas are integrally formed, which helps to reduce the difficulty of manufacturing the antenna system as a whole. In addition, the antennas can also be connected through a feed network, the feed network can be processed on the same PCB, or a plurality of whip antennas are connected on the PCB feed network through a buckle wire, which is equivalent to that a plurality of antennas are integrally arranged, and the whole processing efficiency of the antenna system can be further improved.
The antenna system of the present invention is explained below with a more specific example.
An omni-directional monopole WiFi antenna operating at 2.4GHz was designed, as shown in fig. 4 and 5, with a reflection (S11) of-13.8 dB at 2.4GHz, a horizontal plane out-of-roundness of 0dB, a gain of 1.84dBi, as a perfect omni-directional antenna.
It should be noted that fig. 4 is a software simulation diagram, and therefore has a background with a gradient color. In addition, the plane formed by the x axis and the y axis corresponds to the aforementioned horizontal plane, and the z axis corresponds to the vertical direction.
Since the common gateway device has a generally rectangular structure, an antenna system including four antennas and forming a rectangle will be further described.
Firstly, the four antennas are arranged according to a multi-baseline antenna form which is not collinear horizontally, a transmitting and receiving assembly is not added, and a directional diagram of the antenna is simulated. As shown in fig. 6 and fig. 7, it can be seen that the normal directional diagram of the four-antenna system is also similar to an omnidirectional antenna in the horizontal plane, but the out-of-roundness is 5dB, the antenna system shows a certain directivity (the gains at the 0 °, 90 °, 180 ° and 270 ° points are larger), the gains in the four main directions are-1.03 dB, and the gains are also reduced compared with the single antenna. It should be noted that this is because the practice of using an omnidirectional antenna array to increase the gain of the antenna system usually requires a plurality of omnidirectional antennas to be arranged in the vertical direction, i.e. to increase the size in the z-axis direction, which is also the common method in the second case mentioned in the background art, and not in the horizontal direction as in the present embodiment. However, generally, a plurality of omnidirectional antennas are arranged in a horizontal direction, which is mainly used to improve the throughput of the system by utilizing the antenna space diversity and the multipath effect of signals, but this approach brings the problem of overlapping coverage and reducing the efficiency. The antenna system in this embodiment combines the omnidirectional antenna and the horizontal array arrangement, and further combines the transceiver module, so as to ensure a comprehensive coverage area, and perform beam reconstruction and beam tracking for users in any area, thereby maintaining high-quality network signal coverage of users. This is not in accordance with the principles of the prior art and a more comprehensive result can be achieved.
Then, the simulation is performed by adding the transceiver component to further explain the above effect. By adjusting the parameters of each transceiver module, the amplitude and phase of each antenna can be adjusted, thereby controlling the beam reconstruction of the antenna system.
Illustratively, the parameters of the transceiver component for the first beam reconstruction are set as follows: the antenna 1 and the antenna 3 perform equal power division (50% of power each), the antenna 2 and the antenna 4 do not distribute power, all the antenna delays are 0, as shown in fig. 8, the antenna system gain is 2.23dBi, the antenna main directions are 45 ° and 225 °, and the 3dB beam width is 156 °.
Setting the parameters of the transceiving component for the reconstruction of the second wave beam as follows: the antenna 2, the antenna 3 and the antenna 4 perform unequal power division, the power ratio is 1:2:1 (accounting for 25%, 50% and 25% of the total power of the system), the antenna 1 does not distribute power, all the antenna time delays are 0, as shown in fig. 9, the gain of the antenna system is 2.17dBi, the main direction of the antenna is 180 degrees and 270 degrees, and the beam width is 156 degrees at-3 dB.
As shown in fig. 10, the two-dimensional patterns of the four-antenna system without performing the beam reconstruction and performing the first beam reconstruction and the second beam reconstruction are shown in the figure, respectively, and it can be seen that by changing the parameters of the transceiver module, the beam reconstruction and the beam tracking can be performed for the user in any area, thereby maintaining the high-quality network signal coverage of the user.
Only 2 groups of receiving and transmitting component parameters are demonstrated to influence a directional diagram of a four-antenna system, and in actual use, the power adjustable range of each antenna in the whole antenna system is 0-100%, the phase adjustable range is 0-360 degrees, more beam directions and beam widths can be realized, and accurate coverage for a certain specified user is realized.
A control method of an antenna system according to another embodiment of the present invention is applied to the antenna system described above, and the method includes:
adjusting the amplitude and/or phase of at least one antenna in the antenna system to enable reconstruction and/or tracking of the antenna system beam.
In particular, the adjustment of the amplitude and phase of the respective antenna may be achieved by adjusting the transceiver component parameters, such as power, etc. It should be noted that various different parameter combinations can be selected according to the practical application requirements, so as to implement beam reconstruction and beam tracking for users in any area.
A gateway device of another embodiment of the present invention includes the antenna system as described above.
The gateway device is used as a connector between different networks, and the antenna system is configured, so that the coverage range can be ensured to be comprehensive, and beam reconstruction and beam tracking can be performed on users in any area, thereby maintaining high-quality network signal coverage of the users.
