[0033] Example 1

[0034] Reference Figure 1 , Figure 5~Figure 7, which is a first embodiment of the present invention, provides a SER antenna using a multiple-input multiple-output (MIMO) technology, the device comprising:

[0035] The bearing assembly 100 includes a flange 101, a support rod 102 fixedly connected to a surface of one side of the flange 101, and a power supply module 103 fixedly installed on a surface of the support rod 102;

[0036] Among them, the flange 101 is made of aluminum alloy with the characteristics of light weight, good strength and corrosion resistance. The flange 101 is used to support the support rod 102. The power supply module 103 can ensure that each component in the MIMO system, such as the RF module, the control unit, etc., continuously obtains the required power supply to ensure the stable operation of the system. The MIMO system is an existing technology, and this solution will not be elaborated in detail, and those skilled in the art can clearly understand the working principle.

[0037] The pitch-changing assembly 200 is fixedly disposed on the surface of the support rod 102, and the pitch-changing assembly 200 includes a limiting groove 201 provided on the top surface of the support rod 102, a rotating component 202 fixedly disposed in the limiting groove 201, and a sliding component 203 slidably connected to the rotating component 202;

[0038] The support rod 102 is used to support the rotating component 202 and the rotating component 202. Through the cooperation between the rotating component 202 and the sliding component 203, the distance between the multiple antennas can be flexibly adjusted effectively.

[0039] Also, a flip assembly 300 fixedly disposed on the top surface of the support rod 102 and a telescopic assembly 400 fixedly disposed above the sliding component 203 .

[0040] Among them, the flip component 300 can drive multiple antennas to adjust their angles through the rotation of the output end of the second motor 302c, and the antenna can be reset through the reaction force of the torsion spring 302g. By extending the output end of the cylinder 402a, the telescopic segment 403a of the multiple antennas can be extended, and the telescopic segment 403a can be reset through the reaction force of the spring 403d.

[0041] Specifically, the rotating component 202 includes a motor frame 202a fixedly connected to one side surface of the support rod 102, a first motor 202b adapted to be installed on the inner surface of the motor frame 202a, a rotating roller 202c fixedly installed on one side surface of the inner wall of the limiting groove 201 through a bearing, and an inclined groove 202d opened on the surface of the rotating roller 202c.

[0042] Among them, the output end of the first motor 202b penetrates to the other side surface of the inner wall of the limiting groove 201, and is fixedly connected to the other end of the rotating roller 202c. Turning on the first motor 202b can drive the rotating roller 202c to rotate, so that the rotating roller 202c drives the inclined groove 202d to rotate synchronously.

[0043] Furthermore, the sliding component 203 includes an antenna base 203a slidably connected to the inner wall surface of the limiting groove 201, a protrusion 203b fixedly connected to the bottom surface of the antenna base 203a, a swivel column 203c fixedly installed on the inner wall surface of the antenna base 203a, and a fixed segment 203d hinged to the surface of the swivel column 203c.

[0044] Among them, the antenna base 203a is used to support the rotating column 203c, so that the rotating column 203c supports the fixed segment 203d of the antenna, and the protrusion 203b is slidably connected in the inclined groove 202d. The antenna base 203a is limited by the limiting groove 201, so that the antenna base 203a limits the protrusion 203b, so that when the inclined groove 202d rotates, it can drive the protrusion 203b to move in a straight line, and then the protrusion drives the antenna base 203a, the rotating column 203c and the fixed segment 203d to move in a straight line. The fixed segment 203d is made of stainless steel with excellent corrosion resistance, high strength and suitable for long-term outdoor use. A radio frequency module is fixedly installed inside the fixed segment 203d. The radio frequency module is responsible for signal transmission and reception. In the MIMO system, each antenna port corresponds to a radio frequency module to support simultaneous processing of multiple signals.

[0045] When in use, the first motor 202b is turned on to drive the rotating roller 202c to rotate, so that the rotating roller 202c drives the inclined slot 202d to rotate synchronously, and the antenna base 203a is limited by the limiting slot 201, so that the antenna base 203a limits the protrusion 203b, so that the inclined slot 202d drives the protrusion 203b to move in a straight line through rotation, and then the protrusion drives the antenna base 203a, the rotating column 203c and the fixed segment 203d to move in a straight line, so as to adjust the distance between multiple fixed segments 203d, so as to achieve the effect of flexibly adjusting the spacing of the RF modules inside the fixed segment 203d.

[0046] In summary, by finely adjusting the spacing between RF modules to accurately control the width of the beamforming, the gain of the antenna array is optimized, and the efficiency of the spatial multiplexing provided by the MIMO system using multiple antennas is further improved to increase the system capacity and data transmission rate.

[0047] Example 2

[0048] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that it provides a flip assembly 300 that can simultaneously focus the signals of multiple antennas to a suitable direction through a second motor frame 302b.

[0049] Furthermore, the flip assembly 300 includes a fixing block 301 fixedly connected to the top surface of the support rod 102 , and an extrusion component 302 fixedly disposed on one side of the fixing block 301 .

[0050] The fixing block 301 is used to support the extruded component 302 so that the extruded component 302 can adjust the multiple antennas to appropriate angles at the same time by extrusion.

[0051] Furthermore, the extrusion component 302 includes a motor cover 302a fixedly mounted on the top surface of the support rod 102, a second motor frame 302b fixedly connected to the bottom surface of the inner wall of the motor cover 302a, and a second motor 302c adapted to be mounted on the inner surface of the second motor frame 302b.

[0052] The motor cover 302a is used to protect the second motor frame 302b, and the second motor frame 302b is used to stably support the second motor 302c.

[0053] Preferably, the extrusion component 302 also includes a driving rod 302d fixedly mounted on one side surface of the fixed block 301 through a bearing, a driven rod 302e fixedly connected to the other end of the driving rod 302d, a bevel block 302f fixedly connected to the outer surface of the fixed segment 203d, and a torsion spring 302g fixedly mounted on the surface of the rotary column 203c.

[0054] The output end of the second motor 302c penetrates the outside of the motor cover 302a and is fixedly connected to one end of the driving rod 302d, and the other end of the torsion spring 302g is fixedly connected to the outer surface of the fixed segment 203d.

[0055] When in use, turn on the second motor 302c to drive the driving rod 302d to rotate, and the driving rod 302d drives the driven rod 302e to perform circular motion, so that the driven rod 302e squeezes the inclined surface of the inclined block 302f through the circular motion, so that the position of the inclined block 302f is tilted, and the fixed segment 203d and the radio frequency module are driven by the inclined block 302f to rotate with the rotating column 203c as the center, and a rotational force is applied to the torsion spring 302g, so that the torsion spring 302g undergoes elastic deformation and stores potential energy, and the output end of the second motor 302c is controlled to rotate in the opposite direction, so that the driven rod 302e is out of contact with the inclined block 302f, and the rotational force on the torsion spring 302g is removed, and the reaction force of the torsion spring 302g restores its original shape and releases the stored energy, so that the fixed segment 203d and the radio frequency module are reset.

[0056] In summary, by simultaneously focusing the signals from multiple antennas in the appropriate direction, the signal transmission path is optimized, thereby reducing the bit error rate, so as to further improve the ability of the MIMO system to transmit multiple data streams simultaneously and improve signal quality through spatial multiplexing and spatial diversity technology.

[0057] Example 3

[0058] Reference Figure 1 , Figure 3 and Figure 6 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: a telescopic component 400 can simultaneously adjust multiple antennas to appropriate lengths through a cylinder 402a.

[0059] Furthermore, the telescopic assembly 400 includes a connecting rod 401 fixedly connected to one side surface of the driven rod 302e, a driving component 402 adapted to be installed on the other end of the connecting rod 401, and a driven component 403 fixedly installed above the fixed segment 203d.

[0060] When the driven rod 302e performs circular motion, it can drive the connecting rod 401 to move synchronously, so that the connecting rod 401 drives the driving component 402 to move.

[0061] Furthermore, the driving component 402 includes a cylinder 402a adapted to be installed at the other end of the connecting rod 401, a connecting frame 402b fixedly connected to the output end of the cylinder 402a, and a slide groove 402c opened on the top surface of the connecting frame 402b.

[0062] When the output end of the cylinder 402a extends, it can drive the connecting frame 402b and the sliding groove 402c to move.

[0063] Preferably, the driven component 403 includes a telescopic segment 403a slidably connected to the inner surface of the fixed segment 203d, and a positioning frame 403b fixedly installed on the surface of the telescopic segment 403a.

[0064] Among them, the telescopic segment 403a adopts glass fiber reinforced plastic with light weight, high strength, good corrosion resistance and good dielectric properties. The good dielectric properties can make the telescopic segment 403a have a lower loss factor, thereby reducing the attenuation of the signal during transmission to improve the signal quality. The interior of the telescopic segment 403a is equipped with multiple groups of radiators for transmitting and receiving radio signals to realize the functions of multi-channel input and multi-channel output.

[0065] It should be noted that the driven component 403 further includes a ball 403c slidably connected to the inner surface of the positioning frame 403b, and a spring 403d fixedly mounted on the bottom surface of the inner wall of the fixed segment 203d.

[0066] Among them, the positioning frame 403b is used to limit the ball 403c to prevent the position of the ball 403c from being offset. The ball 403c is also slidably connected in the slide groove 402c. The other end of the spring 403d is fixedly connected to one end of the telescopic segment 403a. The spring 403d is used to reset the telescopic segment 403a.

[0067] When in use, the flip assembly 300 drives the fixed segment 203d and the connecting rod 401 to rotate, while the fixed segment 203d drives the telescopic segment 403a, the positioning frame 403b, the ball 403c and the spring 403d to rotate synchronously, and then drives the cylinder 402a to rotate through the connecting rod 401, so that the cylinder 402a drives the connecting frame 402b and the slide 402c to rotate synchronously, and the cylinder 402a is turned on, so that the output end of the cylinder 402a extends, and drives the connecting frame 402b and the slide 402c to rise. The positioning frame 403b is lifted up through the cooperation of the slide groove 402c and the ball 403c, and then the positioning frame 403b drives the telescopic segment 403a and the radiator to lift up, and at the same time, the telescopic segment 403a applies pressure to the spring 403d to control the output end of the cylinder 402a to be retracted, and the telescopic segment 403a and the radiator are reset through the reaction force of the spring 403d. Through the cooperation of the slide groove 402c and the ball 403c, multiple antennas can be adjusted in length while still being able to adjust the spacing and angle.

[0068] In summary, by accurately adjusting the telescopic segments of multiple antennas to appropriate lengths, the radiation characteristics and directivity of the antennas can be optimized, so that the signal energy can be radiated more concentratedly in the target direction, which can not only improve the signal gain at the receiving end, but also change the signal propagation path and phase to reduce the situation in which the signal reaches the receiving end through multiple paths in the MIMO system, causing multipath interference, thereby improving the accuracy and reliability of signal reception.

[0069] Example 4

[0070] Reference Figures 1 to 7 , which is the fourth embodiment of the present invention. Different from the previous embodiment, this embodiment provides a technology for improving data transmission rate, including a SER antenna of multiple-input multiple-output (MIMO) technology.

[0071] MIMO (Multiple-Input Multiple-Output) technology plays an important role in wireless communications. This technology uses multiple transmitting antennas and receiving antennas at the transmitting end and the receiving end respectively, so that signals are transmitted and received through multiple antennas, thereby significantly improving communication quality.

[0072] The specific implementation method is as follows:

[0073] S1: MIMO systems significantly increase data transmission rates by transmitting multiple independent data streams between multiple antennas simultaneously. Each antenna can transmit data independently, thereby transmitting more information at the same time. By transmitting data simultaneously through multiple antennas, parallel transmission is achieved, which improves the system throughput.

[0074] S2: MIMO system uses multiple antennas to receive the same signal. Even if the signal of one path is attenuated, the signal of other paths can still ensure the communication quality. This spatial diversity improves the reliability and robustness of the signal. By transmitting the same signal at different times, even if the signal quality is poor in a certain period of time, the signal of other periods of time can supplement it.

[0075] S3: By adjusting the phase and amplitude of different antennas, the MIMO system can concentrate energy to send signals in a specific direction, improve the signal strength at the target receiving point, reduce interference, and dynamically adjust the direction and width of the beam according to the location and environment of the receiving end to optimize the signal coverage.

[0076] In summary, MIMO technology is widely used in various communication systems, including but not limited to wireless local area networks (WLANs) such as Wi-Fi 6 (IEEE 802.11ax), cellular networks such as 4G LTE and 5G NR, satellite communications, where multi-antenna systems are used to increase data transmission rates and coverage, and radar systems, where MIMO technology can be used to improve radar resolution and target recognition capabilities.
