Description

Technical Field

[0001] The utility model relates to the technical field of communication technology, in particular to a beam-adjustable antenna with high sidelobe suppression. Background Art

[0002] With the rapid development of wireless communication technology, antenna performance and flexibility are particularly important in wireless networks. Modern wireless communication systems (such as 5G, the Internet of Things, and satellite communications) have increasingly stringent requirements for signal coverage, bandwidth, and quality. Traditional antenna designs have limitations in terms of signal coverage and beam control. Traditional beam-adjustable antennas typically use phase shifters to adjust the beam direction by changing the phase. However, this method has certain limitations in achieving precise beam control and power allocation, with poor sidelobe suppression and difficulty in control, especially in scenarios that require dynamic adaptation to different user needs.

[0003] Therefore, it is necessary to design an antenna with adjustable beam to achieve a more efficient and flexible signal coverage solution. Utility Model Content

[0004] In response to the problems raised in the background technology, the purpose of the present invention is to propose a beam-adjustable antenna with high sidelobe suppression, which aims to achieve a more efficient and flexible signal coverage solution by introducing a radiation modulation device with adjustable and controllable signal power, combined with an antenna power divider and a connector.

[0011] The coaxial line is used to transmit high-frequency signals between the radiation unit and the amplitude modulation device;

[0012] The amplitude modulation device is used to change the amplitudes of a plurality of the radiation units, thereby changing the beam width of the antenna.

[0013] Preferably, the amplitude modulation device, the coaxial line and the power divider are arranged on one side of the support plate; and the radiation unit is arranged on the other side of the support plate.

[0014] The support plate is a reflective plate, and the reflective plate is used to reflect signals.

[0015] It also includes an antenna connector, which is used to connect to the feeder to connect the user equipment and the antenna.

[0016] Preferably, it also includes a radius adjustment button connected to the radius adjustment device.

[0017] Preferably, the number of the radiation units is 3, and the amplitude modulation device adjusts the amplitudes of the radiation units at both ends to change the beam width of the antenna.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] Users can adjust the antenna's beam width in real time according to the needs of specific application scenarios to achieve optimal signal coverage, allowing the antenna to adapt to a variety of environments and usage scenarios. By rationally distributing the signal power of each radiating unit through the power splitter, the signal strength in a specific direction can be effectively enhanced, the signal coverage in the target area can be improved, and blind spots can be reduced.

[0028] With the rapid development of wireless communication technology, antenna performance and flexibility are particularly important in wireless networks. Modern wireless communication systems (such as 5G, the Internet of Things, and satellite communications) have increasingly stringent requirements for signal coverage, bandwidth, and quality. Traditional antenna designs have limitations in terms of signal coverage and beam control. Traditional beam-adjustable antennas typically use phase shifters to adjust the beam direction by changing the phase. However, this approach has certain limitations in achieving precise beam control and power allocation, especially in scenarios that require dynamic adaptation to different user needs.

[0029] Therefore, it is necessary to design an antenna with adjustable beam to achieve a more efficient and flexible signal coverage solution.

[0030] like Figure 1 and 2 As shown, a beam-adjustable antenna with high sidelobe suppression includes a support plate 1, a radiation modulation device 2, a coaxial line 5, a power divider 3 and a radiation unit 4;

[0031] The radiation unit 4 is used for signal radiation;

[0032] The amplitude modulation device 2, the power divider 3 and the radiation unit 4 are all arranged on the support plate 1;

[0033] The power divider 3 is connected to the radiation unit 4 and the amplitude modulation device 2 respectively through the coaxial line 5;

[0034] The power divider 3 is used to distribute the power of the electrical signal to the radiation unit 4;

[0035] The coaxial line 5 is used to transmit high-frequency signals between the radiation unit 4 and the amplitude modulation device 2;

[0036] The amplitude modulation device 2 is used to change the amplitudes of a plurality of the radiation units 4, thereby changing the beam width of the antenna.

[0037] Specifically, the function of the power divider 3 is to evenly distribute the input signal power to multiple radiation units 4. This process ensures that each radiation unit 4 can effectively receive the signal, thereby improving the coverage range and signal strength of the overall device. The radiation unit 4 is used for signal radiation and converts the wireless signal into an electrical signal. The power divider 3 can be designed using microwave technology, with low insertion loss and good input impedance. Among them, the coaxial cable 5 is an important medium for transmitting radio signals, and is used to transmit high-frequency signals between the radiation unit 4 and the amplitude modulation device 2. In addition, the structural design of the coaxial cable 5 isolates the central conductor from the external environment, which can effectively resist external electromagnetic wave interference. When beam adjustment is applied, the output power of the signal source is first determined to ensure that the signal power of the radiation unit 4 remains unchanged. This can be achieved through an appropriate signal source and power amplifier. When the user needs to change the amplitude of the radiation unit 4, the power distribution is adjusted through the amplitude modulation device 2, for example, increasing or decreasing the amplitude of the radiation unit 4. The amplitude is the energy ratio distributed on the radiation unit 4 to achieve the required beam width. It is worth noting that when facing multiple radiation units 4, one or more radiation units 4 can be selected for adjustment, and the beam width of the antenna can also be changed. It has the advantage of good sidelobe suppression, and the radiation pattern is not easy to deform and is easy to control.

[0038] Preferably, the amplitude modulation device 2, the coaxial line 5 and the power divider 3 are arranged on one side of the support plate 1;

[0039] The radiation unit 4 is disposed on the other side of the support plate 1 .

[0040] Specifically, separating the signal processing parts from the radiation unit 4 can reduce signal interference and make it easier for the installer to control the amplitude modulation device 2, thereby changing the antenna's directivity pattern and effectively reducing the energy distribution on the radiation unit 4, thereby achieving the purpose of beamforming. Components with different functions are placed separately, which can simplify the maintenance and inspection process of the system. When replacement or maintenance is required, only specific components need to be touched without interfering with other parts. The separation design provides greater layout flexibility and can optimize space usage according to actual needs. For example, more modulation and distribution units can be arranged on different sides of the support plate 1 to meet different technical requirements.

[0041] Furthermore, the support plate 1 is a reflective plate, and the reflective plate is used to reflect signals.

[0042] Specifically, the reflector can effectively enhance the strength of the signal, increase the signal coverage and effective receiving capability by improving the directivity of the antenna, and improve the overall performance of the antenna. The reflector can help form a better radiation pattern, so that the signal can be concentrated and propagated in the expected direction, reducing invalid radiation and interference, and optimizing the signal reception and transmission efficiency.

[0043] Preferably, an antenna connector 6 is further included, and the antenna connector 6 is used to connect to a feeder line to connect the user equipment and the antenna.

[0044] Specifically, the antenna connector 6 provides a reliable interface, and the user equipment can easily access the antenna to ensure smooth signal transmission. The antenna connector 6 can effectively reduce the loss during signal transmission, improve the performance and efficiency of the overall system, and ensure signal strength. Through the standardized antenna connector 6, different types of base stations can be easily connected.

[0045] Preferably, it also includes an amplitude modulation button 7 connected to the amplitude modulation device 2.

[0046] Specifically, when the amplitude of the radiation unit 4 needs to be adjusted, the amplitude adjustment button 7 allows the user to conveniently adjust the amplitude of the electrical signal of the radiation unit 4, thereby achieving more intuitive control and enhancing the convenience of operation. By adjusting the signal amplitude, the user can affect the shape and size of the beam, optimize the signal coverage range, and ensure better signal reception.

[0047] Preferably, the number of the radiation units 4 is three, and the amplitude modulation device 2 adjusts the amplitudes of the radiation units 4 at both ends to change the beam width of the antenna.

[0048] Specifically, if Figure 3 and Figure 4 As shown, Figure 3 The antenna pattern before the amplitude modulation device 2 adjusts the amplitude of the first radiation unit 4 and the third radiation unit 4, Figure 3 The side lobes are obvious and the main lobe width is small. Figure 4 The antenna pattern after the amplitude modulation device 2 adjusts the amplitude of the first radiation unit 4 and the third radiation unit 4, during the adjustment process Figure 3 The side lobes in the spherical plane gradually become smaller, and the main lobe also becomes larger until it becomes Figure 4 The effect shown has the advantage of being easier to control and having a better antenna beam adjustment effect.

[0049] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific implementations of the present invention without inventive effort, and such implementations will fall within the scope of protection of the present invention.
