[0031] Since the first feed point is connected to the first and second elements respectively, and the first element is connected to the first radiating arm, and the second element is connected to the second radiating arm, when the radio frequency signal is fed into the first feed point, the first element can excite a radiated signal on the first radiating arm, and the second element can excite a radiated signal on the second radiating arm. Simultaneously, since the phase difference between the radiated signals from the first and second radiating arms is a first preset angle, the radiation pattern of the antenna module is deflected along the direction from the first asymmetrical element to the first symmetrical element, thus ensuring strong radiation performance of the antenna module in the direction from the first asymmetrical element to the first symmetrical element. Furthermore, the asymmetrical structure of the first asymmetrical element allows for more flexible arrangement of the second element and the second radiating arm, facilitating the compression of the size of the first asymmetrical element in the first direction, thereby effectively reducing the space occupied by the antenna module. Therefore, when the antenna module is applied to terminal devices such as RRU devices in communication systems, it not only enables smaller terminal device sizes, facilitating deployment in locations such as lower floors, but also ensures high communication performance, thus meeting the requirements for high-quality communication.

[0064] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0065] like Figure 1 As shown, this embodiment of the present disclosure proposes an antenna module 33, including: a first symmetrical element 331, a first asymmetrical element 332, and a first feed point 333. The first symmetrical element 331 includes: a first vibrator 3311 and a first radiating arm 3312 connected sequentially along a first direction, and the first vibrator 3311 and the first radiating arm 3312 are symmetrical along the first direction. The first asymmetrical element 332 and the first symmetrical element 331 are distributed at intervals along the first direction. The first asymmetrical element 332 includes: a second vibrator 3321 and a second radiating arm 3322 connected sequentially along the first direction. The first feed point 333 is connected to the first vibrator 3311 and the second vibrator 3321 respectively. The phase difference between the radiation signal of the first radiating arm 3312 and the radiation signal of the second radiating arm 3322 is a first preset angle, so that the radiation pattern of the antenna module 33 is deflected along the direction from the first asymmetrical element 332 to the first symmetrical element 331.

[0066] It is understandable that, since the first feed point 333 is connected to the first oscillator 3311 and the second oscillator 3321 respectively, and the first oscillator 3311 is connected to the first radiating arm 3312, and the second oscillator 3321 is connected to the second radiating arm 3322, when the radio frequency signal is fed into the first feed point 333, the first oscillator 3311 can excite a radiated signal on the first radiating arm 3312, and the second oscillator 3321 can excite a radiated signal on the second radiating arm 3322. Simultaneously, due to the radiated signal from the first radiating arm 3312 and the radiated signal from the second radiating arm 3322... The signal phase difference is a first preset angle, which causes the radiation pattern of the antenna module 33 to deflect along the direction from the first asymmetric element 332 to the first symmetric element 331, thereby ensuring that the antenna module 33 has strong radiation performance in the direction from the first asymmetric element 332 to the first symmetric element 331. At the same time, by utilizing the asymmetric structure of the first asymmetric element 332, the structural arrangement of the second vibrator 3321 and the second radiating arm 3322 is more flexible, which makes it easier to compress the size of the first asymmetric element 332 in the first direction, thereby effectively reducing the space occupied by the antenna module 33.

[0067] Therefore, when the antenna module 33 is applied to terminal devices such as the RRU (Radio Remote Unit) device 3 in the communication system, it can not only achieve a smaller size of the terminal device, making it easier to deploy the terminal device in locations such as low floors, but also ensure that the terminal device has high communication performance, thereby meeting the requirements of high-quality communication.

[0068] It should be noted that the first feed point 333 is used to feed in radio frequency signals so that the radio frequency signals can be used to generate radiation signals on the first radiation arm 3312 and the second radiation arm 3322 respectively. Conversely, the first feed point 333 is also used to emit the radiation signals received on the first radiation arm 3312 and the second radiation arm 3322. The specific type of the first feed point 333 can be set according to actual needs and there is no limitation. For example, the first feed point 333 can be a rectangular, circular or other shaped metal layer. The first feed point 333 is fed by spring contact, coupling, etc.

[0069] The first symmetrical element 331 is an element symmetrical along a first direction. The first oscillator 3311 and the first radiating arm 3312 are used to cooperate with each other to generate a radiated signal under the excitation of a radio frequency signal. The specific types of the first oscillator 3311 and the first radiating arm 3312 can be set according to actual needs and are not limited thereto. For example, the first oscillator 3311 can be a strip-shaped metal layer and the first radiating arm 3312 can be a block-shaped metal layer. Specifically, the first radiating arm 3312 includes a rectangular part and a triangular part. One side of the rectangular part is connected to one side of the triangular part, and the corner of the triangular part away from the rectangular part is connected to the first oscillator 3311.

[0070] The first asymmetric element 332 is an element that is asymmetric in any direction. The second oscillator 3321 and the second radiating arm 3322 are used to cooperate with each other to generate a radiated signal under the excitation of a radio frequency signal. The specific types of the second oscillator 3321 and the second radiating arm 3322 can be set according to actual needs and are not limited thereto. For example, the second oscillator 3321 and the second radiating arm 3322 can be strip-shaped metal layers.

[0071] The phase difference between the radiation signal of the first radiating arm 3312 and the radiation signal of the second radiating arm 3322 can be set according to actual needs and is not limited. For example, the first preset angle can be 55 degrees so that the radiation pattern of the antenna module 33 is deflected upwards on the vertical plane.

[0072] The radiation pattern of antenna module 33, also known as radiation pattern or far-field pattern, refers to the graph showing how the relative field strength (normalized modulus) of the radiated field changes with direction at a certain distance from antenna module 33.

[0073] The first direction can be the length direction of the antenna module 33, and when the antenna module 33 is applied to terminal devices such as the RRU device 3 in the communication system, the first direction can be the vertical direction of the terminal device.

[0074] The first oscillator 3311 and the first radiating arm 3312 are symmetrical along the first direction, meaning that the axis of symmetry of the first oscillator 3311 and the axis of symmetry of the first radiating arm 3312 are both located in the first direction.

[0075] like Figure 1As shown, in some embodiments, the first symmetrical element 331 further includes: a first conductor 3313, which is arranged along a first direction and is located between the first feed point 333 and the first oscillator 3311, with a first end of the first conductor 3313 connected to the first feed point 333 and a second end of the first conductor 3313 connected to the first oscillator 3311; the first asymmetrical element 332 further includes: a second conductor 3323, which is arranged along a second direction and is located between the first feed point 333 and the second oscillator 3321, with a first end of the second conductor 3323 connected to the first feed point 333 and a second end of the second conductor 3323 connected to the second oscillator 3321.

[0076] The first direction and the second direction are at a second preset angle, the length of the first conductor 3313 and the length of the second conductor 3323 are in a first preset ratio, and the first oscillator 3311 is located at one end of the first radiating arm 3312 near the first asymmetrical element 332, and the second oscillator 3321 is located at one end of the second radiating arm 3322 near the first symmetrical element 331, so that the phase difference between the radiation signal of the first radiating arm 3312 and the radiation signal of the second radiating arm 3322 is the first preset angle.

[0077] It is understandable that, since the first wire 3313 is located between the first feed point 333 and the first oscillator 3311, and the first end of the first wire 3313 is connected to the first feed point 333 and the second end of the first wire 3313 is connected to the first oscillator 3311, the first feed point 333 can feed radio frequency signals to the first oscillator 3311 through the first wire 3313. At the same time, impedance matching is performed using the first wire 3313 to ensure the high radiation performance of the first radiating arm 3312.

[0078] Since the second wire 3323 is located between the first feed point 333 and the second oscillator 3321, and the first end of the second wire 3323 is connected to the first feed point 333, and the second end of the second wire 3323 is connected to the second oscillator 3321, the first feed point 333 can feed radio frequency signals to the second oscillator 3321 through the second wire 3323. At the same time, impedance matching is performed using the second wire 3323 to ensure the high radiation performance of the second radiating arm 3322.

[0079] Since the first oscillator 3311 is located at the end of the first radiating arm 3312 near the first asymmetric element 332, and the second oscillator 3321 is located at the end of the second radiating arm 3322 near the first symmetric element 331, the first radiating arm 3312 and the second radiating arm 3322 are 180 degrees opposite to each other. At the same time, since the length of the first conductor 3313 and the length of the second conductor 3323 are in a first preset ratio, the phase difference between the radiated signal of the first radiating arm 3312 and the radiated signal of the second radiating arm 3322 can reach a first preset angle, thereby realizing the deflection of the radiation pattern of the antenna module 33 and meeting the requirements of high-quality communication.

[0080] It should be noted that the first conductor 3313 is used for signal transmission and impedance matching between the first feed point 333 and the first oscillator 3311. The specific type of the first conductor 3313 can be set according to actual needs and is not limited thereto. For example, the first conductor 3313 can be a strip-shaped metal layer that is close to a snake shape. Specifically, the direction of the first conductor 3313 from the second end to the first end is as follows: it is set along the first direction and extends in the direction close to the first feed point 333, after being bent, it is set along the second direction and extends in the direction away from the first asymmetric oscillator 332, after being bent, it is set along the first direction and extends in the direction close to the first feed point 333, after being bent, it is set along the second direction and extends in the direction close to the first asymmetric oscillator 332.

[0081] The second conductor 3323 is used for signal transmission and impedance matching between the first feed point 333 and the second oscillator 3321. The specific type of the second conductor 3323 can be set according to actual needs and is not limited thereto. For example, the second conductor 3323 can be a strip-shaped metal layer that is close to a straight line.

[0082] The first preset ratio can be set according to actual needs and is not limited thereto. For example, the length of the first wire 3313 is greater than the length of the second wire 3323, and the setting of the first preset ratio makes the phase difference between the first wire 3313 and the second wire 3323 125 degrees. Combined with the 180-degree opposite direction between the first radiating arm 3312 and the second radiating arm 3322, the first preset angle is 55 degrees.

[0083] The second preset angle can be set according to actual needs and is not limited thereto. For example, the second preset angle can be 90 degrees. Specifically, the second direction can be the width direction of the antenna module 33. When the antenna module 33 is applied to terminal devices such as the RRU device 3 in the communication system, the second direction can be the horizontal direction of the terminal device.

[0084] like Figure 1As shown, in some embodiments, the antenna module 33 further includes a combining wire 334, which is disposed between the first feed point 333 and the first wire 3313 and the second wire 3323. The first end of the combining wire 334 is connected to the first end of the first wire 3313 and the first end of the second wire 3323, respectively. The second end of the combining wire 334 extends in a direction away from the first asymmetric element 332 and is connected to the first feed point 333. The first end of the combining wire 334 is disposed in a first direction, and the second end of the combining wire 334 is disposed in a second direction after being bent. The length of the combining wire 334 is one-quarter of the wavelength of the radiated signal.

[0085] It is understandable that, since the combining wire 334 is disposed between the first feed point 333 and the first wire 3313 and the second wire 3323, and the first end of the combining wire 334 is connected to the first end of the first wire 3313 and the first end of the second wire 3323 respectively, and the second end of the combining wire 334 extends in a direction away from the first asymmetric element 332 and is connected to the first feed point 333, the first feed point 333 can feed radio frequency signals to the first oscillator 3311 through the combining wire 334 and the first wire 3313, and feed radio frequency signals to the second oscillator 3321 through the combining wire 334 and the second wire 3323.

[0086] Meanwhile, since the length of the combining conductor 334 is one-quarter of the wavelength of the radiated signal, the combining conductor 334 can not only cooperate with the first conductor 3313 and the second conductor 3323 to achieve impedance matching, but also increase the linewidth of the unit path. This solves the problem of uncontrolled radiation pattern caused by port impedance and phase confusion due to the different positions and shapes of the first symmetrical element 331 and the first asymmetrical element 332, thereby ensuring the high radiation efficiency of the antenna module 33.

[0087] It should be noted that the combining wire 334 is used for signal transmission and impedance matching between the first feed point 333 and the first oscillator 3311, and between the first feed point 333 and the second oscillator 3321. The specific type of the combining wire 334 can be set according to actual needs and there is no limitation. For example, the combining wire 334 can be a strip-shaped metal layer that is close to L-shaped.

[0088] like Figure 2As shown, in some embodiments, the first oscillator 3311 includes: a first part 33111, a second part 33112, and a third part 33113. The first part 33111 is arranged along a second direction and is symmetrical along a first direction. The middle part of the first part 33111 is connected to the second end of the first radiating arm 3312 and the second end of the first wire 3313, respectively. The first end of the second part 33112 is connected to the first end of the first part 33111 and is arranged along the first direction. The first end of the third part 33113 is connected to the second end of the first part 33111 and is arranged along the first direction. The third part 33113 and the second oscillator 3321 are spaced apart along the first direction. The second part 33112 and the third part 33113 are symmetrical along the first direction, and the second ends of the second part 33112 and the third part 33113 are bent and arranged along the second direction and far apart from each other.

[0089] It is understandable that, since the first end of the second part 33112 is connected to the first end of the first part 33111, and the first end of the third part 33113 is connected to the second end of the first part 33111, the first part 33111, the second part 33112, and the third part 33113 form a near-U-shaped oscillator structure. Furthermore, since the first part 33111 is symmetrical along the first direction, and the second part 33112 and the third part 33113 are symmetrical along the first direction, the first part 33111, the second part 33112, and the third part 33113 form a first oscillator 3311 symmetrical along the first direction. At the same time, since the middle part of the first part 33111 is connected to the second end of the first radiating arm 3312 and the first wire 3313 respectively, the radio frequency signal transmitted by the first wire 3313 can be excited to generate a radiated signal on the first radiating arm 3312 with the cooperation of the first part 33111, the second part 33112, and the third part 33113, thereby meeting the communication requirements.

[0090] Since the second end of the second part 33112 and the second end of the third part 33113 are bent and arranged along the second direction and far apart from each other, not only does the first element 3311 have a large length, maintaining the high radiation efficiency of the first radiating arm 3312, but it also makes the first element 3311 and the second element 3321 have a large gap, thereby reducing the coupling between the first element 3311 and the second element 3321. Thus, while ensuring that the antenna module 33 has a small size in the first direction, the antenna module 33 also has high radiation performance.

[0091] It should be noted that the first part 33111, the second part 33112, and the third part 33113 are used to constitute the first oscillator 3311. The specific types of the first part 33111, the second part 33112, and the third part 33113 can be set according to actual needs and there are no restrictions. For example, the first part 33111 can be a strip of metal that is close to a straight line, and the second part 33112 and the third part 33113 can be strips of metal that are close to an L-shape, that is, the first oscillator 3311 is a metal structure that is close to a Z-shape.

[0092] The distance between the third part 33113 and the second oscillator 3321 can be set according to actual needs and is not limited. For example, the distance between the third part 33113 and the second oscillator 3321 can be 0.41 times the wavelength of the radiation signal.

[0093] like Figure 1 As shown, in some embodiments, the second oscillator 3321 is arranged along the first direction, and the second oscillator 3321 and the first oscillator 3311 are distributed at intervals. The first end of the second oscillator 3321 is connected to the second end of the second radiating arm 3322 and the second conductor 3323, respectively. The second end of the second oscillator 3321 is arranged along the second direction after being bent.

[0094] It is understandable that, since the first end of the second oscillator 3321 is connected to the second end of the second radiating arm 3322 and the second wire 3323 respectively, the radio frequency signal transmitted by the second wire 3323 can be excited to generate a radiated signal on the second radiating arm 3322 with the cooperation of the second oscillator 3321, thereby meeting the communication requirements.

[0095] In this design, since the second end of the second element 3321 is bent and arranged along the second direction, the second element 3321 not only has a large length, maintaining the high radiation efficiency of the second radiating arm 3322, but also has a large gap between the first element 3311 and the second element 3321, thereby reducing the coupling between the first element 3311 and the second element 3321. Thus, while ensuring that the antenna module 33 has a small size in the first direction, the antenna module 33 also has high radiation performance.

[0096] It should be noted that the specific type of the second oscillator 3321 can be set according to actual needs, and there are no restrictions on it. For example, the second oscillator 3321 can be a metal layer that is close to an L-shape.

[0097] like Figure 1As shown, in some embodiments, the second radiating arm 3322 is arranged along the first direction, the first end of the second radiating arm 3322 is connected to the second end of the second oscillator 3321 and the second wire 3323 respectively, and the second end of the second radiating arm 3322 is arranged along the second direction after being bent.

[0098] It is understandable that, since the first end of the second radiating arm 3322 is connected to the second end of the second oscillator 3321 and the second wire 3323 respectively, the radio frequency signal transmitted by the second wire 3323 can be excited to generate a radiated signal on the second radiating arm 3322 with the cooperation of the second oscillator 3321, thereby meeting the communication requirements.

[0099] Since the second end of the second radiating arm 3322 is bent and set along the second direction, the second radiating arm 3322 not only has a large length and maintains a high radiation efficiency, but also has a small size in the first direction, so as to ensure that the antenna module 33 has high radiation performance while also having a small volume.

[0100] It should be noted that the specific type of the second radiating arm 3322 can be set according to actual needs, and there is no restriction on it. For example, the second radiating arm 3322 can be a metal layer that is close to an L-shape.

[0101] like Figure 1 As shown, in some embodiments, the first radiating arm 3312 is provided with a slot 33121, which is provided along a second direction.

[0102] It is understandable that by setting the slot 33121, the current path on the first radiating arm 3312 can be lengthened, thereby ensuring the high radiation efficiency of the first radiating arm 3312.

[0103] It should be noted that the specific type of groove 33121 can be set according to actual needs, and there is no restriction on it. For example, groove 33121 can be a nearly straight groove, and groove 33121 is also symmetrical along the first direction.

[0104] like Figure 3As shown, in some embodiments, the antenna module 33 further includes: a second symmetrical element 335, a second asymmetrical element 336, and a second feed point 337. The second symmetrical element 335 and the first symmetrical element 331 are spaced apart along a third direction. The second symmetrical element 335 includes: a third vibrator 3351 and a third radiating arm 3352 connected sequentially along a first direction, and the third vibrator 3351 and the third radiating arm 3352 are symmetrical along the first direction. The second asymmetrical element 336 and the second symmetrical element 335 are spaced apart along the first direction, and the second asymmetrical element 336 and the second symmetrical element 335 are spaced apart along the first direction. The first asymmetric element 332 is spaced apart along a third direction. The second asymmetric element 336 includes a fourth element 3361 and a fourth radiating arm 3362 connected sequentially along a first direction. The second feed point 337 is connected to the third element 3351 and the fourth element 3361 respectively. The third direction and the first direction form a third preset angle. The phase difference between the radiation signal of the third radiating arm 3352 and the radiation signal of the fourth radiating arm 3362 is the first preset angle, so that the radiation pattern of the antenna module 33 is deflected along the direction from the second asymmetric element 336 to the second symmetric element 335.

[0105] Understandably, since the second feed point 337 is connected to the third oscillator 3351 and the fourth oscillator 3361 respectively, and the third oscillator 3351 is connected to the third radiating arm 3352, and the fourth oscillator 3361 is connected to the fourth radiating arm 3362, when the radio frequency signal is fed into the second feed point 337, the third oscillator 3351 can excite a radiated signal on the third radiating arm 3352, and the fourth oscillator 3361 can excite a radiated signal on the fourth radiating arm 3362. Simultaneously, due to the radiated signal from the third radiating arm 3352 and the radiated signal from the fourth radiating arm 3362... The signal phase difference is a first preset angle, which causes the radiation pattern of the antenna module 33 to deflect along the direction from the second asymmetric element 336 to the second symmetric element 335, thereby ensuring that the antenna module 33 has strong radiation performance in the direction from the second asymmetric element 336 to the second symmetric element 335. At the same time, by utilizing the asymmetric structure of the second asymmetric element 336, the structural arrangement of the fourth element 3361 and the fourth radiating arm 3362 is more flexible, which makes it easier to compress the size of the second asymmetric element 336 in the first direction, thereby effectively reducing the space occupied by the antenna module 33.

[0106] Therefore, when the antenna module 33 is applied to terminal devices such as the RRU device 3 in a communication system, the cooperation of the first symmetrical element 331, the first asymmetrical element 332, the second symmetrical element 335, and the second asymmetrical element 336 can not only achieve a smaller size for the terminal device, making it easier to deploy the terminal device in locations such as low floors, but also ensure that the terminal device has high communication performance, thereby meeting the requirements for high-quality communication.

[0107] It should be noted that the second feed point 337 is used to feed in radio frequency signals so that the radio frequency signals can generate radiation signals on the third radiation arm 3352 and the fourth radiation arm 3362 respectively. Conversely, the second feed point 337 is also used to emit the radiation signals received on the third radiation arm 3352 and the fourth radiation arm 3362. The specific type of the second feed point 337 can be set according to actual needs and there is no limitation. For example, the second feed point 337 can be a rectangular, circular or other shaped metal layer. The second feed point 337 is fed by spring contact, coupling, etc.

[0108] The second symmetrical element 335 is a symmetrical element along the first direction. The third oscillator 3351 and the third radiating arm 3352 are used to cooperate with each other to generate a radiated signal under the excitation of the radio frequency signal. The specific types of the third oscillator 3351 and the third radiating arm 3352 can be set according to actual needs and are not limited thereto. For example, the third oscillator 3351 can be a strip-shaped metal layer and the third radiating arm 3352 can be a block-shaped metal layer. Specifically, the third radiating arm 3352 includes a rectangular part and a triangular part. One side of the rectangular part is connected to one side of the triangular part, and the corner of the triangular part away from the rectangular part is connected to the third oscillator 3351.

[0109] The second asymmetric element 336 is an element that is asymmetric in any direction. The fourth oscillator 3361 and the fourth radiating arm 3362 are used to cooperate with each other to generate a radiated signal under the excitation of a radio frequency signal. The specific types of the fourth oscillator 3361 and the fourth radiating arm 3362 can be set according to actual needs and are not limited thereto. For example, the fourth oscillator 3361 and the fourth radiating arm 3362 can be strip-shaped metal layers.

[0110] The third preset angle can be set according to actual needs and is not limited thereto. For example, the third preset angle can be 90 degrees. Specifically, the third direction can be the thickness direction of the antenna module 33. When the antenna module 33 is applied to terminal devices such as the RRU device 3 in the communication system, the third direction can be the horizontal direction of the terminal device.

[0111] The symmetry of the third oscillator 3351 and the third radiating arm 3352 along the first direction means that the axis of symmetry of the third oscillator 3351 and the axis of symmetry of the third radiating arm 3352 are both located in the first direction.

[0112] like Figure 3As shown, in some embodiments, the second symmetrical element 335 further includes: a third conductor 3353, which is arranged along a first direction and is located between the second feed point 337 and the third vibrator 3351, with the first end of the third conductor 3353 connected to the second feed point 337 and the second end of the third conductor 3353 connected to the third vibrator 3351; the second asymmetrical element 336 further includes: a fourth conductor 3363, which is arranged along a second direction and is located between the second feed point 337 and the fourth vibrator 3361, with the first end of the fourth conductor 3363 connected to the second feed point 337 and the second end of the fourth conductor 3363 connected to the fourth vibrator 3361.

[0113] Wherein, the second direction and the first direction are at a second preset angle, the second direction and the third direction are at a fourth preset angle, the length of the third conductor 3353 and the length of the fourth conductor 3363 are in a second preset ratio, and the third oscillator 3351 is located at one end of the third radiating arm 3352 near the second asymmetric element 336, and the fourth oscillator 3361 is located at one end of the fourth radiating arm 3362 away from the second symmetric element 335, so that the phase difference between the radiation signal of the third radiating arm 3352 and the radiation signal of the fourth radiating arm 3362 is a first preset angle.

[0114] It is understandable that, since the third conductor 3353 is located between the second feed point 337 and the third oscillator 3351, and the first end of the third conductor 3353 is connected to the second feed point 337, and the second end of the third conductor 3353 is connected to the third oscillator 3351, the second feed point 337 can feed radio frequency signals to the third oscillator 3351 through the third conductor 3353. At the same time, impedance matching is performed using the third conductor 3353 to ensure the high radiation performance of the third radiating arm 3352.

[0115] Since the fourth wire 3363 is located between the second feed point 337 and the fourth oscillator 3361, and the first end of the fourth wire 3363 is connected to the second feed point 337, and the second end of the fourth wire 3363 is connected to the fourth oscillator 3361, the second feed point 337 can feed radio frequency signals to the fourth oscillator 3361 through the fourth wire 3363. At the same time, impedance matching is performed using the fourth wire 3363 to ensure the high radiation performance of the fourth radiating arm 3362.

[0116] Since the third radiating element 3351 is located at the end of the third radiating arm 3352 close to the second asymmetric element 336, and the fourth radiating element 3361 is located at the end of the fourth radiating arm 3362 away from the second symmetric element 335, the first radiating arm 3312 and the second radiating arm 3322 are not reversed. At the same time, since the lengths of the third conductor 3353 and the fourth conductor 3363 are in a second preset ratio, the phase difference between the radiated signal of the third radiating arm 3352 and the radiated signal of the fourth radiating arm 3362 can reach a first preset angle, thereby realizing the deflection of the radiation pattern of the antenna module 33 and meeting the requirements of high-quality communication.

[0117] It should be noted that the third conductor 3353 is used for signal transmission and impedance matching between the second feed point 337 and the third oscillator 3351. The specific type of the third conductor 3353 can be set according to actual needs and there is no limitation thereto. For example, the third conductor 3353 can be a strip-shaped metal layer.

[0118] The fourth conductor 3363 is used for signal transmission and impedance matching between the second feed point 337 and the fourth oscillator 3361. The specific type of the fourth conductor 3363 can be set according to actual needs and is not limited thereto. For example, the fourth conductor 3363 can be a strip of metal layer that is close to a straight line.

[0119] The second preset ratio can be set according to actual needs, and there are no restrictions on it. For example, the length of the third conductor 3353 is greater than the length of the fourth conductor 3363, and the setting of the second preset ratio makes the first preset angle 55 degrees.

[0120] The fourth preset angle can be set according to actual needs and there are no restrictions on it. For example, the fourth preset angle can be 90 degrees.

[0121] like Figure 4 As shown, in some embodiments, the third conductor 3353 includes: a plurality of fourth portions 33531 arranged along a first direction and a plurality of fifth portions 33532 arranged along a second direction, wherein the plurality of fourth portions 33531 and the plurality of fifth portions 33532 are distributed sequentially at intervals along the first direction and are connected end to end.

[0122] It is understandable that, since multiple fourth parts 33531 and multiple fifth parts 33532 are distributed sequentially and connected end to end along the first direction, the third conductor 3353 has a serpentine structure. This not only gives the third conductor 3353 a large length to meet the requirements of the second preset ratio, but also gives the third conductor 3353 a small size in the first direction. Thus, while ensuring that the antenna module 33 has high radiation performance, it also has a small volume.

[0123] It should be noted that multiple fourth parts 33531 and multiple fifth parts 33532 are used to form a serpentine third conductor 3353. The specific types of the fourth parts 33531 and the fifth parts 33532 can be set according to actual needs and there are no restrictions. For example, the fourth parts 33531 and the fifth parts 33532 can be linear strip metal layers.

[0124] like Figure 4 As shown, in some embodiments, the third oscillator 3351 includes: a sixth portion 33511, a seventh portion 33512, and an eighth portion 33513. The sixth portion 33511 is arranged along a second direction and is symmetrical along a first direction. The middle portion of the sixth portion 33511 is connected to the second end of the third radiating arm 3352 and the third conductor 3353, respectively. The first end of the seventh portion 33512 is connected to the first end of the sixth portion 33511 and is arranged along the first direction. The first end of the eighth portion 33513 is connected to the second end of the sixth portion 33511 and is arranged along the first direction. The eighth portion 33513 and the fourth radiating arm 3362 are spaced apart along the first direction. The seventh portion 33512 and the eighth portion 33513 are symmetrical along the first direction.

[0125] Understandably, since the first end of the seventh part 33512 is connected to the first end of the sixth part 33511, and the first end of the eighth part 33513 is connected to the second end of the sixth part 33511, the sixth part 33511, the seventh part 33512, and the eighth part 33513 form a near-U-shaped oscillator structure. Furthermore, since the sixth part 33511 is symmetrical along the first direction, and the seventh part 33512 and the eighth part 33513 are symmetrical along the first direction, the sixth part... 33511, the seventh part 33512, and the eighth part 33513 constitute a third oscillator 3351 symmetrical along the first direction. Meanwhile, since the middle part of the sixth part 33511 is connected to the second end of the third radiating arm 3352 and the third wire 3353 respectively, the radio frequency signal transmitted by the third wire 3353 can be excited to radiate a signal on the third radiating arm 3352 with the cooperation of the sixth part 33511, the seventh part 33512, and the eighth part 33513, thereby meeting the communication requirements.

[0126] It should be noted that the sixth part 33511, the seventh part 33512, and the eighth part 33513 are used to form the third oscillator 3351. The specific types of the sixth part 33511, the seventh part 33512, and the eighth part 33513 can be set according to actual needs and there is no restriction. For example, the sixth part 33511, the seventh part 33512, and the eighth part 33513 can be strips of metal that are close to the shape of a straight line.

[0127] like Figure 3 As shown, in some embodiments, the fourth radiating arm 3362 is arranged along the first direction, and the fourth radiating arm 3362 and the third oscillator 3351 are spaced apart. The first end of the fourth radiating arm 3362 is connected to the second end of the fourth oscillator 3361 and the second end of the fourth wire 3363, respectively. The second end of the fourth radiating arm 3362 is arranged along the second direction after being bent.

[0128] It is understandable that, since the first end of the fourth radiating arm 3362 is connected to the second end of the fourth oscillator 3361 and the fourth wire 3363 respectively, the radio frequency signal transmitted by the fourth wire 3363 can be excited to generate a radiated signal on the fourth radiating arm 3362 with the cooperation of the fourth oscillator 3361, thereby meeting the communication requirements.

[0129] In this design, the second end of the fourth radiating arm 3362 is bent and positioned along the second direction, which not only gives the fourth radiating arm 3362 a larger length and maintains its high radiation efficiency, but also gives the third vibrator 3351 and the fourth radiating arm 3362 a larger gap, thereby reducing the coupling between them. Thus, while ensuring that the antenna module 33 has a smaller size in the first direction, it also gives it higher radiation performance.

[0130] It should be noted that the specific type of the fourth radiating arm 3362 can be set according to actual needs, and there is no restriction on it. For example, the fourth radiating arm 3362 can be a metal layer that is close to an L-shape.

[0131] like Figure 3 As shown, in some embodiments, the fourth vibrator 3361 is arranged along the first direction, the first end of the fourth vibrator 3361 is connected to the second end of the fourth radiating arm 3362 and the fourth wire 3363 respectively, and the second end of the fourth vibrator 3361 is arranged along the second direction after being bent.

[0132] It is understandable that, since the first end of the fourth oscillator 3361 is connected to the second end of the fourth radiating arm 3362 and the fourth wire 3363 respectively, the radio frequency signal transmitted by the fourth wire 3363 can be excited to generate a radiated signal on the fourth radiating arm 3362 with the cooperation of the fourth oscillator 3361, thereby meeting the communication requirements.

[0133] In this design, since the second end of the fourth element 3361 is bent and arranged along the second direction, the fourth element 3361 not only has a large length, maintaining the high radiation efficiency of the fourth radiating arm 3362, but also the fourth radiating arm 3362 has a small size in the first direction, thus ensuring that the antenna module 33 has high radiation performance while also having a small volume.

[0134] It should be noted that the specific type of the fourth oscillator 3361 can be set according to actual needs, and there are no restrictions on it. For example, the fourth oscillator 3361 can be a metal layer that is close to an L-shape.

[0135] like Figure 1 and Figure 3 As shown, in some embodiments, the antenna module 33 further includes a substrate 338, which includes a first side and a second side in opposite positions. A first symmetrical element 331, a first asymmetrical element 332 and a first feed point 333 are respectively disposed on the first side, and a second symmetrical element 335, a second asymmetrical element 336 and a second feed point 337 are respectively disposed on the second side.

[0136] It is understandable that by setting up the substrate 338, the first symmetrical element 331, the first asymmetrical element 332, the first feed point 333, the second symmetrical element 335, the second asymmetrical element 336, and the second feed point 337 are integrated and arranged, thereby facilitating the use of the cooperation of the first symmetrical element 331, the first asymmetrical element 332, the second symmetrical element 335, and the second asymmetrical element 336 to achieve high-performance communication of the antenna module 33.

[0137] It should be noted that the length direction of the substrate 338 can be a first direction, the width direction can be a second direction, and the thickness direction can be a third direction. The first symmetrical element 331 and the second symmetrical element 335 are arranged opposite to each other in the thickness direction of the substrate 338, and the first asymmetrical element 332 and the second asymmetrical element 336 are arranged opposite to each other in the thickness direction of the substrate 338.

[0138] like Figure 5 and Figure 6 As shown, this disclosure also proposes an RRU device 3, including: a housing 31, a radio frequency module 32 and at least one antenna module 33 as described in this disclosure. The radio frequency module 32 is disposed in the housing 31 and is used for the conversion of baseband signals and radio frequency signals. The antenna module 33 is disposed in the housing 31, and the first feed point 333 of the antenna module is connected to the radio frequency terminal of the radio frequency module 32.

[0139] It is understandable that, since the first feed point 333 is connected to the RF terminal of the RF module 32, and the first feed point 333 is connected to the first oscillator 3311 and the second oscillator 3321 respectively, the first oscillator 3311 is connected to the first radiating arm 3312, and the second oscillator 3321 is connected to the second radiating arm 3322, when the RF module 32 converts the baseband signal into an RF signal and feeds it to the first feed point 333, it can use the first oscillator 3311 to excite a radiated signal on the first radiating arm 3312, and use the second oscillator 3321 to excite a radiated signal on the second radiating arm 3322. Simultaneously, since the first radiating arm 3312... The phase difference between the radiated signal of the first element and the radiated signal of the second radiating arm 3322 is a first preset angle, and the radiation pattern of the antenna module 33 is deflected along the direction from the first asymmetric element 332 to the first symmetric element 331, thereby ensuring that the antenna module 33 has strong radiation performance in the direction from the first asymmetric element 332 to the first symmetric element 331; at the same time, by utilizing the asymmetric structure of the first asymmetric element 332, the structural arrangement of the second element 3321 and the second radiating arm 3322 is more flexible, thereby facilitating the compression of the size of the first asymmetric element 332 in the first direction, and thus effectively reducing the space occupied by the antenna module 33.

[0140] Therefore, not only can the RRU device 3 be made smaller in size, making it easier to deploy the RRU device 3 in locations such as low floors, but it can also ensure that the RRU device 3 has high communication performance, thereby meeting the requirements for high-quality communication.

[0141] It should be noted that the housing 31 is used to accommodate the radio frequency module 32 and the antenna module 33. The specific type of housing 31 can be set according to actual needs and is not limited thereto. In particular, since the antenna module 33 occupies a small space, the housing 31 has a small size, thus enabling the RRU device 3 to be used as a Micro RRU.

[0142] The radio frequency (RF) module 32 is used for the conversion between baseband signals and RF signals. For example, it converts the baseband signals of the core network into RF signals and transmits these RF signals using the antenna module 33; or it receives RF signals using the antenna module and converts them back into baseband signals to be transmitted back to the core network. The specific type of the RF module 32 can be configured according to actual needs and is not limited thereto.

[0143] The radio frequency (RF) terminal of the RF module 32 is connected not only to the first feed point 333 but also to the second feed point 337. This allows the antenna module 33 to achieve high-performance communication through the cooperation of the first symmetrical element 331, the first asymmetrical element 332, the second symmetrical element 335, and the second asymmetrical element 336.

[0144] like Figure 5 and Figure 6 As shown, in some embodiments, the housing 31 includes: a metal base 311 and a non-metallic cover 312. A radio frequency (RF) module 32 is disposed within the metal base 311, with its RF terminal and baseband terminal extending outside the metal base 311 respectively. The non-metallic cover 312 is fitted onto the metal base 311 to form a receiving cavity, and an antenna module 33 is disposed within this cavity, with the RF terminal of the RF module 32 located within the cavity. The direction from the first asymmetric element 332 to the first symmetric element 331 in the antenna module is the same as the direction from the metal base 311 to the non-metallic cover 312. Furthermore, the first side surface of the substrate 338 in the antenna module and the inner wall of the non-metallic cover 312 are positioned opposite each other.

[0145] It is understandable that, since the antenna module 33 is located in the cavity between the metal base 311 and the non-metallic cover 312, not only can the non-metallic material of the non-metallic cover 312 be used to ensure the efficient and stable radiation of the antenna module 33, but the metal material of the metal base 311 can also be used to reflect the radiated signal, thereby making the antenna module 33 have stronger radiation performance in the direction from the first asymmetric element 332 to the first symmetric element 331.

[0146] It should be noted that the specific type of the metal base 311 can be set according to actual needs and there is no limitation. For example, the metal base 311 can be a hemispherical base with a cavity inside, and the main body of the radio frequency module 32 is set in the cavity.

[0147] The specific type of the non-metallic cover 312 can be set according to actual needs and there are no restrictions. For example, the non-metallic cover 312 can be a cylindrical cover, and the non-metallic cover 312 can be made of materials such as fiberglass.

[0148] The expansion components of the RRU device 3 can also be set on the metal base 311, such as: indicator lights, which are set on the metal base 311 and electrically connected to the radio frequency module 32; and cascading connectors, which are set on the metal base 311 and electrically connected to the cascading end of the radio frequency module 32.

[0149] When the RRU device 3 is arranged, the metal base 311 is located below and the non-metallic cover 312 is located above.

[0150] like Figure 5 and Figure 6 As shown, in some embodiments, the housing 31 further includes a heat sink 313, which is sleeved on the end of the metal base 311 away from the non-metallic cover 312, and the heat sink 313 is provided with a heat dissipation structure.

[0151] Understandably, since the heat sink 313 is fitted onto the end of the metal base 311 away from the non-metallic cover 312, the heat sink 313 can dissipate the heat on the metal base 311 using the heat dissipation structure, thereby preventing the metal base 311 from affecting the operating efficiency of the radio frequency module 32 due to excessive temperature, and thus ensuring the high-performance communication of the RRU device 3.

[0152] It should be noted that the heat sink 313 is used for heat dissipation of the metal base 311. The specific type of heat sink 313 can be set according to actual needs and there is no limitation. For example, the heat sink 313 is adapted to the shape of the metal base 311. Multiple hollow slots, multiple heat sinks and other heat dissipation structures can be set on the heat sink 313.

[0153] Since the RF module 32 generates less heat, the heat sink 313 is sufficient to ensure the heat dissipation of the metal base 311.

[0154] like Figure 7 As shown, in some embodiments, at least one antenna module 33 includes: a first module 3301, a second module 3302, a third module 3303, and a fourth module 3304. The first feed point 333 and the second feed point 337 of the first module 3301 are respectively connected to the first radio frequency terminal of the radio frequency module 32. The first feed point 333 and the second feed point 337 of the second module 3302 are respectively connected to the second radio frequency terminal of the radio frequency module 32. The first feed point 333 and the second feed point 337 of the third module 3303 are respectively connected to the third radio frequency terminal of the radio frequency module 32. The first feed point 333 and the second feed point 337 of the fourth module 3304 are respectively connected to the fourth radio frequency terminal of the radio frequency module 32. The first module 3301, the second module 3302, the third module 3303, and the fourth module 3304 are uniformly distributed along the circumference of the receiving cavity.

[0155] It is understandable that, since the first module 3301, the second module 3302, the third module 3303 and the fourth module 3304 are uniformly distributed along the circumference of the cavity, the radio frequency module 32 can utilize the cooperation of the first module 3301, the second module 3302, the third module 3303 and the fourth module 3304 to efficiently radiate signals along the direction from the first asymmetric element 332 to the first symmetric element 331, thereby giving the antenna module 33 high radiation performance.

[0156] It should be noted that the first module 3301, the second module 3302, the third module 3303 and the fourth module 3304 are all antenna modules 33.

[0157] like Figure 5 and Figure 6As shown, in some embodiments, the RRU device 3 further includes a bracket 34, on which the housing 31 is detachably mounted, and the bracket 34 is detachably mounted on the bearing surface.

[0158] It is understandable that, since the housing 31 is detachably mounted on the bracket 34, and the bracket 34 is detachably mounted on the bearing surface, the installation of the RRU device 3 is more flexible and convenient, which facilitates the deployment of the RRU device 3 in locations such as low floors.

[0159] It should be noted that the bracket 34 is used to support the housing 31. The specific type of the bracket 34 can be set according to actual needs and is not limited thereto. For example, the bracket 34 includes a support arm and a wall mount. The first end of the support arm and the heat sink 313 are detachably connected by multiple bolts. The second end of the support arm and the wall mount are detachably connected by multiple bolts. The wall mount is detachably mounted on a load-bearing surface such as a wall by multiple bolts.

[0160] In this embodiment, the RRU device 3 comes with a built-in antenna module 33. The integrated design is not only easy to deploy, but also more acceptable to users.

[0161] Based on the integrated and miniaturized design, the RRU device 3 can be set to a volume of less than 2L and a weight of less than 5kg. Compared with the traditional 160W high-power RRU module, which has a volume of 24L and a weight of 22kg, the RRU device 3 in this embodiment is easier to install, and its small size will not attract attention, reducing the probability of being damaged.

[0162] The RRU device 3 in this embodiment adopts an aesthetically pleasing lamp-like design to avoid psychological interference from users who fear radiation, and also to further prevent users from deliberately damaging it.

[0163] Specifically, the RRU device 3 in this embodiment can be deployed in low-rise buildings in urban villages and other building complexes. Based on the pitch angle pointing adjustment capability of the antenna module 33 in the RRU device 3, while maintaining axial suppression, it maximizes the adaptability to the application scenario of low-to-high attack in urban villages and maximizes the gain.

[0164] like Figure 8 As shown, this disclosure also proposes a communication system, including: a BBU (Building Baseband Unit) module 1, at least one pHUB (hub) module 2, and at least one RRU device 3 as described in this disclosure. The first communication terminal of the BBU module 1 is connected to the core network equipment, the second communication terminal of the BBU module 1 is connected to the first communication terminal of the pHUB module 2, and the second communication terminal of the pHUB module 2 is connected to the baseband terminal of the radio frequency module 32 in the RRU device 3.

[0165] It is understandable that, since the first feed point 333 is connected to the RF terminal of the RF module 32, and the first feed point 333 is connected to the first oscillator 3311 and the second oscillator 3321 respectively, the first oscillator 3311 is connected to the first radiating arm 3312, and the second oscillator 3321 is connected to the second radiating arm 3322, when the RF module 32 converts the baseband signal into an RF signal and feeds it to the first feed point 333, it can use the first oscillator 3311 to excite a radiated signal on the first radiating arm 3312, and use the second oscillator 3321 to excite a radiated signal on the second radiating arm 3322. Simultaneously, since the first radiating arm 3312... The phase difference between the radiated signal of the first element and the radiated signal of the second radiating arm 3322 is a first preset angle, and the radiation pattern of the antenna module 33 is deflected along the direction from the first asymmetric element 332 to the first symmetric element 331, thereby ensuring that the antenna module 33 has strong radiation performance in the direction from the first asymmetric element 332 to the first symmetric element 331; at the same time, by utilizing the asymmetric structure of the first asymmetric element 332, the structural arrangement of the second element 3321 and the second radiating arm 3322 is more flexible, thereby facilitating the compression of the size of the first asymmetric element 332 in the first direction, and thus effectively reducing the space occupied by the antenna module 33.

[0166] Therefore, not only can the RRU device 3 be made smaller in size, making it easier to deploy the RRU device 3 in locations such as low floors, but it can also ensure that the RRU device 3 has high communication performance, thereby meeting the requirements for high-quality communication.

[0167] Furthermore, the communication system utilizes BBU module 1, pHUB module 2, and RRU device 3 at its terminal to transmit and receive signals, which not only ensures high communication performance but also features a simple structure and ease of construction and deployment, thereby effectively improving the flexibility and convenience of the communication system.

[0168] It should be noted that BBU module 1 is an important component of the mobile base station. BBU module 1 is mainly responsible for processing baseband signals. The specific type of BBU module 1 can be set according to actual needs, and there are no restrictions on it.

[0169] The main function of pHUB module 2 is to regenerate, shape, and amplify the received signal to extend the network's transmission distance. Simultaneously, it concentrates all nodes around itself as the central node. As a type of HUB module, pHUB module 2 can be called a micro-hub, or Pico HUB. The specific type of pHUB module 2 can be configured according to actual needs and is not limited thereto.

[0170] The number of pHUB modules 2 and RRU devices 3 can be set according to actual needs and is not limited. Specifically, pHUB modules 2 can be set to one, two, three, four, etc. When there are multiple pHUB modules 2, they can be connected in parallel to the second communication terminal of BBU module 1, or the first communication terminal of one pHUB module 2 can be connected to the second communication terminal of BBU module 1, with the remaining pHUB modules 2 cascaded sequentially to that pHUB module 2. Similarly, RRU devices 3 can be set to one, two, three, four, etc. When there are multiple RRU devices 3, they can be connected in parallel to the second communication terminal of pHUB modules 2, or one RRU device 3 can be connected to the second communication terminal of BBU module 1, with the remaining RRU devices 3 cascaded sequentially to that RRU device 3.

[0171] The RRU device 3 is powered by the pHUB module 2, so there is no need to run a power cord to draw power remotely or draw power from the nearest household during deployment. The pHUB module 2 can usually be deployed in the computer room, which is convenient for drawing power. This makes the use of the communication system more convenient.

[0172] like Figure 9 and Figure 10 As shown, in some embodiments, at least one pHUB module 2 includes: a first pHUB module 201 and a second pHUB module 202. The first communication terminal of the first pHUB module 201 and the first communication terminal of the second pHUB module 202 are respectively connected to the second communication terminal of the BBU module 1; or the first communication terminal of the first pHUB module 201 and the second communication terminal of the BBU module 1 are connected, and the first terminal of the second pHUB module 202 is connected to the cascade terminal of the first pHUB module 201.

[0173] It is understandable that, since the first communication terminal of the first pHUB module 201 and the first communication terminal of the second pHUB module 202 are respectively connected to the second communication terminal of the BBU module 1, the first pHUB module 201 and the second pHUB module 202 are connected in parallel at the second communication terminal of the BBU module 1, thereby enabling the BBU module 1 to achieve high-performance communication using the RRU device 3 at the end of the first pHUB module 201 and the RRU device 3 at the end of the second pHUB module 202.

[0174] Since the first communication terminal of the first pHUB module 201 is connected to the second communication terminal of the BBU module 1, and the first terminal of the second pHUB module 202 is connected to the cascade terminal of the first pHUB module 201, the first pHUB module 201 and the second pHUB module 202 are cascaded at the second communication terminal of the BBU module 1, thereby enabling the BBU module 1 to achieve high-performance communication using the RRU device 3 at the end of the first pHUB module 201 and the RRU device 3 at the end of the second pHUB module 202.

[0175] It should be noted that both the first pHUB module 201 and the second pHUB module 202 are pHUB modules 2.

[0176] like Figure 9 and Figure 10 As shown, in some embodiments, at least one RRU device 3 includes: a first RRU device 301 and a second RRU device 302. The baseband terminals of the RF module 32 in the first RRU device 301 and the second RRU device 302 are respectively connected to the second communication terminal of the pHUB module 2; or the baseband terminal of the RF module 32 in the first RRU device 301 is connected to the second communication terminal of the pHUB module 2, and the baseband terminal of the RF module 32 in the second RRU device 302 is connected to the cascade terminal of the RF module 32 in the first RRU device 301.

[0177] It is understandable that, since the baseband terminals of the RF module 32 in the first RRU device 301 and the RF module 32 in the second RRU device 302 are respectively connected to the second communication terminal of the pHUB module 2, the first RRU device 301 and the second RRU device 302 are connected in parallel at the second communication terminal of the pHUB module 2, thereby enabling the pHUB module 2 to achieve high-performance communication using the first RRU device 301 and the second RRU device 302.

[0178] Since the baseband end of the radio frequency module 32 in the first RRU device 301 is connected to the second communication end of the pHUB module 2, and the baseband end of the radio frequency module 32 in the second RRU device 302 is connected to the cascade end of the radio frequency module 32 in the first RRU device 301, the first RRU device 301 and the second RRU device 302 are cascaded at the second communication end of the pHUB module 2, thereby enabling the pHUB module 2 to achieve high-performance communication using the first RRU device 301 and the second RRU device 302.

[0179] It should be noted that both the first RRU device 301 and the second RRU device 302 are RRU devices 3 in this embodiment.

[0180] Among them, pHUB module 2 can support four levels of cascading. When pHUB module 2 is placed on the exterior wall of a building, it can reduce the need for long-distance fiber optic transmission between BBU module 1 and pHUB module 2.

[0181] Cell splitting is supported under the same pHUB module 2, which can split into two 2×100MNR cells and two 2×20M LTE cells. For situations with high capacity requirements, if the capacity of one cell with eight RRU devices 3 is insufficient, another cell can be split out under the same pHUB module 2 to increase system capacity.

[0182] RRU device 3 can support 2W / channel power output from the built-in antenna, and can also support an external antenna interface. It can use DAS (Distributed Antenna System) to solve the single-point coverage problem of the information apartment.

[0183] like Figure 8 As shown, in some embodiments, the communication system further includes: at least one optoelectronic hybrid cable 4, which is disposed between the second communication end of the pHUB module 2 and the baseband end of the radio frequency module 32 in the RRU device 3, and the first end of the optoelectronic hybrid cable 4 is connected to the second communication end of the pHUB module 2, and the second end of the optoelectronic hybrid cable 4 is connected to the baseband end of the radio frequency module 32 in the RRU device 3.

[0184] It is understandable that, since the first end of the optoelectronic hybrid cable 4 is connected to the second communication end of the pHUB module 2, and the second end of the optoelectronic hybrid cable 4 is connected to the baseband end of the radio frequency module 32 in the RRU device 3, signal transmission can be achieved between the second communication end of the pHUB module 2 and the baseband end of the radio frequency module 32 in the RRU device 3 using the optoelectronic hybrid cable 4, thereby ensuring high-performance communication of the communication system.

[0185] It should be noted that the optical-electric hybrid cable 4 is used to transmit optical-electric signals. The specific type of the optical-electric hybrid cable 4 can be set according to actual needs, and there are no restrictions on it.

[0186] In traditional solutions, the end of the communication system is a distributed system, including RRU modules, feeders, power dividers, couplers, wall-mounted antennas, etc., which is complex and difficult to deploy. In this embodiment, the traditional distributed system is replaced by pHUB module 2, optoelectronic hybrid cable 4 and RRU device 3, which greatly reduces the types and number of devices and significantly reduces the difficulty of deployment.

[0187] Furthermore, due to the passive nature of devices such as couplers and wall-mounted antennas, once installed, it is impossible to intelligently monitor the nodes later, and manual troubleshooting is inefficient, resulting in communication performance that cannot meet usage requirements. In this embodiment, however, each device's head end is an active digital head end, which can monitor all the statuses of each node in the network management system. If there is any human-caused damage or other problems, timely action can be taken, significantly improving fault handling efficiency and greatly enhancing the user experience.

[0188] Compared to traditional distributed systems, whose feeders are typically 13mm or 23mm in diameter, the fiber optic hybrid cable 4 has a smaller diameter, which can be set to 7mm. It is small and lightweight, making construction and wiring convenient, and its appearance is relatively concealed after deployment.

[0189] like Figure 8 As shown, in some embodiments, the communication system further includes: a WDM (Wavelength Division Multiplexing) module 5 and a splitter 6. The WDM module 5 and the splitter 6 are disposed between the second communication terminal of the BBU module 1 and the first communication terminal of the pHUB module 2. The first communication terminal of the WDM module 5 is connected to the second communication terminal of the BBU module 1, the second communication terminal of the WDM module 5 is connected to the first communication terminal of the splitter 6, and the second communication terminal of the splitter 6 is connected to the first communication terminal of the pHUB module 2.

[0190] It is understandable that, since the first communication terminal of WDM module 5 is connected to the second communication terminal of BBU module 1, and the second communication terminal of WDM module 5 is connected to the first communication terminal of splitter 6, and the second communication terminal of splitter 6 is connected to the first communication terminal of pHUB module 2, stable signal transmission is achieved between BBU module 1 and pHUB module 2, thereby ensuring high-performance communication of the communication system.

[0191] It should be noted that wavelength division multiplexing is a technology that uses multiple lasers to simultaneously transmit multiple laser beams of different wavelengths on a single optical fiber. The specific type of WDM module 5 can be set according to actual needs, and there are no restrictions on it.

[0192] Splitter 6 can separate multiple frequency band signals input on the line in a wireless communication system into a single frequency band and output them to different communication lines. The specific type of splitter 6 can be set according to actual needs and there are no restrictions on it. Splitter 6 can belong to ODF (Optical Distribution Frame).

[0193] like Figure 8As shown, in some embodiments, the communication system further includes at least one ONU (Optical Distribution Network) module 7, wherein the first communication end of the ONU module 7 is connected to the second communication end of the BBU module 1.

[0194] It is understandable that since the first communication terminal of the ONU module 7 is connected to the second communication terminal of the BBU module 1, signal transmission can be achieved between the BBU module 1 and the ONU module 7, thereby enabling the BBU module 1 to communicate with the user terminal using the ONU module 7, thus meeting different communication needs.

[0195] It should be noted that ONU module 7 is an FTTH (Fiber to the Home) optical cable network based on PON (Passive Optical Network) equipment. The specific type of ONU module 7 can be configured according to actual needs, and there are no restrictions on it.

[0196] In the traditional scheme, WDM module 5 and splitter 6 are usually used for signal transmission between OLT (Optical Line Terminal) module and ONU module 7. In this embodiment, WDM module 5 and splitter 6 are reused between OLT module and ONU module 7.

[0197] In the communication system of this embodiment, the backhaul part of BBU module 1 is connected to the core network equipment through transmission methods such as SPN / PTN / Internet. The fronthaul part uses WDM module 5 to couple the OLT optical signal and transmits the baseband signal generated by BBU module 1 and the OLT optical signal to the ODF rack through the existing PON network optical fiber. The splitter 6 of the ODF rack is connected to pHUB module 2 or ONU module 7.

[0198] Based on the communication system of this embodiment, the power consumption of each node is about 60W, and the output is 42W. The total power consumption of the 8 nodes plus the pHUB module 2 is about 550W. In the traditional solution, the power consumption of the main device with 2×160W NR and 2×40W LTE using the DAS system and outputting to 8 points is equivalent to the power consumption of the solution in this embodiment. In the traditional solution, the power consumption of a single RRU module exceeds 1000W, about 1200W. In the solution of this embodiment, the power consumption is reduced by 50%, and the power consumption is significantly reduced.

[0199] The communication system of this embodiment can have the following beneficial effects:

[0200] It can reduce the consumption of optical fiber resources: In traditional FTTH networks, each user terminal requires an independent ONU module 7 to receive and transmit optical signals. The communication system in this embodiment can reduce the consumption of optical fiber resources and improve the utilization rate of optical fiber, which helps to reduce network construction costs and improve the return on investment.

[0201] It can simplify the network structure: By integrating the RRU device 3 with the home broadband, it is possible to achieve unified management and maintenance of wireless and wired networks, thereby simplifying the network structure and reducing operation and maintenance costs.

[0202] Improve network reliability: The end RRU device 3 supports remote maintenance by network management, which can improve network reliability, reduce failure rate, and improve user experience.

[0203] Flexible network expansion: Because it is based on PON network transmission, the transmission of a certain wavelength can be flexibly increased or decreased without changing the existing network structure. This helps to adapt to constantly changing needs and realize flexible network expansion.

[0204] In summary, the commercial value of the communication system in this embodiment is mainly reflected in reducing fiber optic resource consumption, simplifying network structure, improving network reliability, flexible network expansion, and innovative business models. These advantages can help operators reduce costs, improve network performance, and expand business scope, thereby gaining greater commercial value.
