Description

Communication device TECHNICAL FIELD

[0001] The present disclosure belongs to the technical field of communication, and particularly relates to a communication device. BACKGROUND

[0002] In recent years, China's new information infrastructure construction at sea is in full swing. With the advent of the 5G era, the marine economy is ushering in new opportunities for scale development. Through accelerating 5G coverage in the open sea, basic telecom enterprises will extend 5G to the sea, integrate into the construction of "smart ocean", and continuously accelerate the construction of 5G networks in the B28 (B5 / B28, etc.) frequency band. As the main frequency band promoted by major operators, N41 (B41) will become increasingly important in future near-sea deployment.

[0003] Traditional sea area communication mainly includes two types. One is satellite transmission, which requires professional equipment and is expensive, making it difficult to meet the needs of ordinary customers. The other is to rely on the 4G network already covered in coastal areas, but the coverage distance is short and cannot meet the needs of customers at sea. A relatively innovative solution is to use B28+B41 coastal base station super-coverage + ferry cabin repeater station to enhance coverage, but due to the use of omnidirectional antennas, the radiation efficiency is low, and the size is large, which is not convenient to install. At the same time, the repeater station is a relay and amplification of wireless information, and the use of terminals must have a 5G module, which has high requirements for user equipment, and in the case of many ships, it is easy to produce self-excitation, which seriously affects the Internet experience.

[0083] To continuously expand maritime coverage, effectively improve the user experience inside ship cabins, and contribute to building a long-coverage, high-quality 5G smart marine network, this disclosure provides a communication device for realizing communication connections between base stations and terminals, the structural block diagram of which is shown in Figure 1. It should be noted that, according to the direction of signal transmission, the signal transmission process between the base station and the terminal can be divided into an uplink communication link and a downlink communication link. Specifically, the uplink communication link refers to the process of signal transmission from the terminal to the base station, and the downlink communication link refers to the process of signal transmission from the base station to the terminal. Referring to Figure 1, the communication device of this disclosure includes an antenna module 1, a signal processing module 2, and a 5G CPE module 3. In the uplink communication link, the terminal sends the terminal signal to be uploaded to the 5G CPE module 3. The 5G CPE module 3 performs signal conversion on the terminal signal for transmission. The converted terminal signal is transmitted to the signal processing module 2, which processes it and then sends it to the antenna module 1. For example, amplifying the terminal signal can avoid distortion and attenuation, improving signal stability. Then, the antenna module 1 radiates the processed signal to the base station in the form of electromagnetic waves, completing the transmission of the terminal signal. In the downlink communication link, the base station signal emitted by the base station propagates in the form of electromagnetic waves. After receiving the base station signal, the antenna module 1 transmits it to the signal processing module 2 for processing. The processed signal is then transmitted to the 5G CPE module 3 for conversion so that the terminal can access it.

[0084] In some examples, in the communication link from the terminal to the base station, i.e., in the uplink communication link, the signal processing module 2 includes a fixed attenuator and a final-stage amplifier. The fixed attenuator is mainly used to adjust signal strength, equalize signal strength in multi-signal systems, and control signal strength during testing and measurement. The final-stage amplifier, also known as a power amplifier, is mainly used to amplify the signal in the communication link, ensuring sufficient signal strength for longer transmission distances.

[0085] In the communication link where the signal is transmitted from the base station to the terminal, i.e., in the downlink communication link, the signal processing module 2 includes a low-noise amplifier and a filter. The low-noise amplifier can amplify weak signals while reducing noise in the communication link, improving signal quality and receiving sensitivity. The filter can remove noise, suppress noise interference, and select the desired frequency to pass through while filtering out unwanted signals. In some examples, in communication links transmitting high-frequency signals, such as N41 signals (operating frequency of 2515MHz-2675MHz), the filter can be a SAW (Surface Acoustic Wave) filter. In communication links transmitting low-frequency signals, such as N28 signals (operating frequency of around 700MHz), the filter can be a bandpass SAW filter, with an operating frequency band of, for example, 758MHz-788MHz.

[0086] In some examples, the 5G CPE module 3 can convert the received base station signal into a WiFi signal for user terminal devices to access. Of course, the 5G CPE module 3 can also reserve a LAN port to allow users to expand the network via a wireless router (AP).

[0087] It should be noted that the antenna in this disclosure is a transceiver antenna, meaning it can be used simultaneously as both a receiving and transmitting antenna, capable of both transmitting and receiving electromagnetic wave signals. To ensure simultaneous transmission of base station and terminal signals and improve signal transmission rate, the communication device of this disclosure also includes a first isolation module 41 and a second isolation module 42 for separating base station and terminal signals. Specifically, the first isolation module 41 is located between the antenna module 1 and the signal processing module 2, and the second isolation module 42 is located between the signal processing module 2 and the 5G CPE module 3. By using isolation modules 41 / 42, the signal transmission rate can be improved, signal latency reduced, and user experience enhanced.

[0088] In some examples, the antenna module 1 may include multiple antenna elements 11, all of which are directional antennas, and each antenna element 11 has a different beam direction. That is, each antenna element 11 can receive and radiate electromagnetic wave energy in different directions, thus enabling the antenna module 1 to radiate electromagnetic wave energy in a specific direction or receive electromagnetic wave energy from a specific direction, improving the directivity of the antenna module 1 and the security of communication. In other examples, the antenna module 1 may include only one antenna element 11, and this antenna element 1 is an omnidirectional antenna. That is, one antenna element 11 can receive signals from all directions and radiate signals outwards in all directions. Thus, while ensuring normal signal transmission, the number of antenna elements 11 can be reduced, thereby reducing costs. Furthermore, since omnidirectional antennas have a lower failure rate, maintenance costs can also be reduced. The specific structure of the antenna module 1 and the communication device of this application will be described below with reference to specific embodiments.

[0089] First, we introduce a specific embodiment of the antenna module 1, which includes multiple antenna elements 11, and each antenna element 11 is a directional antenna.

[0090] Figure 2 is a schematic diagram of the antenna module 1 provided in this disclosure. As shown in Figure 2, the antenna module 1 is an omnidirectional antenna device. Each antenna element 11 in the antenna module 1 covers a certain angular range, and the angular range covered by each antenna element 11 is different. For example, the antenna module 1 in Figure 2 adopts a six-sector configuration. Specifically, the antenna module 1 includes a supporting structure and antenna elements 11 disposed on the side of the supporting structure. The supporting structure is a hollow hexagonal prism, and each side of the prism is provided with an antenna element 11. Each antenna element 11 includes two first elements 111 arranged side by side, two second elements 112 disposed between the two first elements 111, and an auxiliary element 114 disposed between the two second elements 112. It should be noted that the structure of the auxiliary element 114 is exactly the same as that of the other two second elements 112, but it is only for ensuring the integrity of the antenna and is not used to transmit signals in actual use. Thus, each antenna element 11 includes two first elements 111 and two second elements 112, and the antenna module 1 includes a total of twelve first elements 111 and twelve second elements 112. Each element is equipped with a corresponding signal transmission link, meaning that each element can transmit base station signals and terminal signals. It should be noted that both the first elements 111 and the second elements 112 are single-polarized elements, meaning that the signals radiated by the first elements 111 and the second elements 112 have a specific polarization direction, such as horizontal polarization, vertical polarization, ±45° polarization, etc.

[0091] Specifically, the first oscillator operates at a low frequency of 700MHz using FDD (Frequency Division Multiplexing) mode, while the second oscillator operates at a high frequency of 2.6GHz using TDD (Time Division Multiplexing) mode. Both the first and second oscillators are integrated transceivers with a common aperture design. For ease of description, the first oscillator is referred to as the low-frequency oscillator 111, and the second oscillator is referred to as the high-frequency oscillator 112.

[0092] In the communication link between the low-frequency vibrator 111, signal processing module 2, and 5G CPE module 3, the first isolation module 41 includes a first duplexer, and the second isolation module 42 includes a second duplexer. The first duplexer is connected between the low-frequency vibrator 111 and the signal processing module 2, and the second duplexer is connected between the signal processing module 2 and the 5G CPE module 3. In the communication link between the high-frequency vibrator 112, signal processing module 2, and 5G CPE module 3, the first isolation module 41 includes a first circulator, and the second isolation module 42 includes a second circulator. The first circulator is connected between the high-frequency vibrator 112 and the signal processing module 2, and the second circulator is connected between the signal processing module 2 and the 5G CPE module 3. In other words, in the communication link transmitting low-frequency signals, a first duplexer and a second duplexer are configured to separate base station signals and terminal signals. In the communication link transmitting high-frequency signals, a first circulator and a second circulator are configured to separate base station signals and terminal signals. Duplexers and circulators can isolate base station signals and terminal signals, ensuring that both reception and transmission can work normally at the same time.

[0093] Furthermore, continuing to refer to Figures 2 and 3, in order to reduce the mutual influence between the high-frequency vibrator 112 and the low-frequency vibrator 111, the high-frequency vibrator 112 and the low-frequency vibrator 111 have different heights. Specifically, for each antenna element 11, the high-frequency vibrator 112 and the low-frequency vibrator 111 are arranged side by side, and the height of the low-frequency vibrator 111 in the direction away from the supporting structure is greater than the height of the high-frequency vibrator 112 in the same direction.

The first reference electrode 102 is disposed on a supporting structure and has a first hollow portion V3. The first radiating structure 101 is disposed on the supporting structure through the first hollow pattern; the first transmission line 103 is connected to the first radiating structure 101. The first reference electrode 102 and the first radiating structure 101 can form a current loop, and the first transmission line 103 is used to transmit radio frequency signals to the first radiating structure 101.

[0095] The first radiating structure 101 includes a first support component 1013, a first radiating electrode 1011, and a second radiating electrode 1012. Specifically, the first support component 1013 may include a first support portion 1013a and a second support portion 1013b arranged side-by-side, and a first connecting portion 1013c connecting the first support portion 1013a and the second support portion 1013b. The first connecting portion 1013c is disposed on the bearing structure and located within the first hollow portion V3. One end of the first support portion 1013a is connected to the first connecting portion 1013c, and the other end is connected to the first radiating electrode 1011. One end of the second support portion 1013b is connected to the first connecting portion 1013c, and the other end is connected to the second radiating electrode 1012. A first transmission line 103 is connected to the first radiating electrode 1011 and, through a first through-hole penetrating the first radiating electrode 1011, is connected to a first connecting electrode 104. The first connecting electrode 104 is connected to the second radiating electrode 1012.

[0096] Referring to Figure 4, the first support portion 1013a and the second support portion 1013b in the first support assembly 1013 are both integrally formed with the first connecting portion 1013c. In order to provide stable support, the width of the portion of the first connecting portion 1013c located on the load-bearing structure is greater than the distance between the first support portion 1013a and the second support portion 1013b.

[0097] Referring to Figure 4, the first radiating electrode 1011 includes a first main body portion 1011a and a first fixing portion 1011b connected to the first main body portion 1011a; the second radiating electrode 1012 includes a second main body portion 1012a and a second fixing portion 1012b connected to the second main body portion 1012a; the first main body portion 1011a has a first opening V1, and the second main body portion 1012a has a second opening V2; the first transmission line 103 is connected to the first fixing portion 1011b and is connected to the first connecting electrode 104 through a first through-hole penetrating the first fixing portion 1011b, and the first connecting electrode 104 is connected to the second fixing portion 1012b. In this case, by providing the first opening V1 on the first main body portion 1011a and the second opening V2 on the second main body portion 1012a, the current path can be extended and the gain improved.

[0098] Furthermore, the outer contours of both the first main body 1011a and the second main body 1012a include multiple side edges. The interior angle formed by any two adjacent side edges of the outer contour of the first main body 1011a is an obtuse angle; the interior angle formed by any two adjacent side edges of the outer contour of the second main body 1012a is also an obtuse angle. Since the interior angles of both the first main body 1011a and the second main body 1012a are obtuse angles, electromagnetic wave reflection can be reduced, thus lowering losses. Furthermore, the first opening V1 has the same shape as the outer contour of the first main body 1011a; the second opening V2 has the same shape as the outer contour of the second main body 1012a. For example, if the outer contour of the first main body 1011a is a regular hexagon, the shape of the first opening V1 is also a regular hexagon; if the outer contour of the second main body 1012a is a regular hexagon, the shape of the second opening V2 is also a regular hexagon. Of course, in some examples, the shape of the first opening V1 is different from the outer contour of the first main body 1011a; the shape of the second opening V2 is different from the outer contour of the second main body 1012a. For example, the outer contour of the first main body 1011a is a regular hexagon, while the shape of the first opening V1 is a circle; the outer contour of the second main body 1012a is a regular hexagon, while the shape of the second opening V2 is a circle.

[0099] Figure 7 is a perspective view of the high-frequency oscillator 112 according to an embodiment of the present disclosure; Figure 8 is a front view of the high-frequency oscillator 112 according to an embodiment of the present disclosure; Figure 9 is a top view of the second reference electrode 202 of the high-frequency oscillator 112 according to an embodiment of the present disclosure; as shown in Figures 10-12, the high-frequency oscillator 112 in this embodiment of the present disclosure includes a second reference electrode 202, a second radiating structure 201, and a second transmission line 203. The second reference electrode 202 is disposed on a supporting structure and has a second hollow portion V4. The second radiating structure 201 passes through the second hollow portion V4 and is disposed on the supporting structure; the second transmission line 203 is connected to the second radiating structure 201. The second reference electrode 202 and the second radiating electrode 201 can form a current loop, and the second transmission line 203 is used to transmit radio frequency signals to the second radiating structure 201.

[0100] The second radiating structure 201 includes a third radiating electrode 2011, a fourth radiating electrode 2012, a second electrode 204, and a second support assembly 2013. The second support assembly 2013 specifically includes a third support portion 2013a and a fourth support portion 2013b arranged side-by-side, and a second connecting portion 2013c connecting the third support portion 2013a and the fourth support portion 2013b. The second connecting portion 2013c is disposed on the supporting structure and located within the second hollow portion V4. One end of the third support portion 2013a is connected to the second connecting portion 2013c, and the other end is connected to the third radiating electrode 2011. One end of the fourth support portion 2013b is connected to the second connecting portion 2013c, and the other end is connected to the fourth radiating electrode 2012. The second transmission line 203 is connected to the third radiating electrode 2011 and is connected to the second electrode 204 through a second through-hole penetrating the third radiating electrode 2011. The second electrode 204 is connected to the fourth radiating electrode 2012.

[0101] Referring to Figure 7, the third support portion 2013a and the fourth support portion 2013b in the second support assembly 2013 are both integral with the second connecting portion 2013c. In order to provide stable support, the width of the portion of the second connecting portion 2013c located on the load-bearing structure is greater than the distance between the third support portion 2013a and the fourth support portion 2013b.

[0102] Referring again to Figure 7, both the third radiating electrode 2011 and the fourth radiating electrode 2012 include a first side and a second side, a third side and a fourth side, and a first connecting edge and a second connecting edge, all arranged opposite each other. For the third radiating electrode 2011, the two ends of the first side are connected to the third side and the fourth side, respectively. One end of the second side is connected to the third side via the first connecting edge, and the other end of the second side is connected to the fourth side via the second connecting edge. The two interior angles formed by the first connecting edge with the third side and the second side are both obtuse angles. For the fourth radiating electrode 2012, the first side is adjacent to the first side of the third radiating patch. The two ends of the first side are connected to the third side and the fourth side, respectively. One end of the second side is connected to the third side via the first connecting edge, and the other end of the second side is connected to the fourth side via the second connecting edge. The two interior angles formed by the first connecting edge with the third side and the second side are both obtuse angles. In other words, both the third radiating electrode 2011 and the fourth radiating electrode 2012 can be obtained by chamfering a square patch. The third radiating electrode 2011 and the fourth radiating electrode 2012 of this structure can not only extend the current path to achieve antenna miniaturization, but also reduce microwave loss.

[0103] When the low-frequency oscillator 111 adopts the structure shown in Figure 4, the maximum side length of the first radiating electrode 1011 and the second radiating electrode 1012 is 22 mm, and the height of the first support component 1013 is 98 mm. Simulation of this low-frequency oscillator 111 yields a horizontal radiation pattern as shown in Figure 10, where the gain of the low-frequency oscillator 111 can reach 7.6 dBi. When the high-frequency oscillator 112 adopts the structure shown in Figure 7, the maximum side length of the third radiating electrode 2011 and the fourth radiating electrode 2012 is 18 mm, and the height of the first support component 1013 is 36.5 mm. Simulation of this low-frequency oscillator 111 yields a horizontal radiation pattern as shown in Figure 11, where the gain of the low-frequency oscillator 111 can reach 8.3 dBi.

[0104] When the high-frequency vibrator 112 and the low-frequency vibrator 111 are used to form an antenna element 11, and six antenna elements 11 are used to form an antenna module 1, the specific structure is shown in Figure 2. At this time, the radiation pattern of the antenna module 1 at a low frequency of 700MHz is shown in Figure 12, and the radiation pattern of the antenna module 1 at a high frequency of 2.6GHz is shown in Figure 13. As shown in Figures 12 and 13, it can be seen that the antenna module 1 of this embodiment can achieve a beam gain of 9.2dBi, a horizontal beamwidth of 77° and a vertical beamwidth of 45° in the low-frequency band, and a horizontal coverage roll-off of only 1.9dB; in the high-frequency band, it achieves a beam gain of 12.2dBi, a horizontal beamwidth of 53° and a vertical beamwidth of 20°, and a horizontal coverage roll-off of 2.9dB, which has a very large coverage capability.

[0105] In some examples, the second reference electrode 202 in the second radiation structure 201 and the first reference electrode 102 in the first radiation structure 101 can be integrally formed. This structure is simple and easy to control.

[0106] In some examples, the first radiating structure 101 in the low-frequency oscillator 111 and the second radiating structure 201 in the high-frequency oscillator 112 can both be made of sheet metal.

[0107] In some examples, the supporting structure can be a hollow structure, and the feed network in antenna module 1 can be disposed within the hollow cavity of the supporting structure, connected to the first transmission line 103 and the second transmission line 203 in each of the antenna elements 11. For example, the feed network may include a first feed network and a second feed network. The first transmission line 103 in each antenna element 11 can be electrically connected to the first feed network through a through-hole penetrating the supporting structure, and the second transmission line 203 in each antenna element 11 can be electrically connected to the second feed network through a through-hole penetrating the supporting structure. In this case, the structure of antenna module 1 is simple and easy to miniaturize.

[0108] In some examples, referring to Figures 2 and 3, the antenna element 11 also includes a first isolation component 113 corresponding to the high-frequency vibrator 112. The orthographic projection of the high-frequency vibrator 112 onto the supporting structure lies within the area defined by the orthographic projection of the corresponding first isolation component 113 onto the supporting structure. The first isolation component 113 prevents mutual interference between the high-frequency vibrator 112 and the low-frequency vibrator 111. Specifically, the first isolation component 113 can be a ring-shaped fence structure formed by sequentially splicing isolation plates, for example, a square fence structure formed by sequentially splicing four isolation plates.

[0109] In some examples, referring to Figure 2, the support structure can be composed of a plurality of sequentially connected support parts 12, with one antenna element 11 disposed on each support part 12. A second isolation component 13 is disposed between any two interconnected support parts 12, and one antenna element 11 is disposed between two adjacent second isolation components 13. The second isolation component 13 is provided to prevent mutual interference between adjacent antenna elements 11.

[0110] In some examples, the communication device also includes a selection module 5 connected between the antenna module 1 and the signal processing module 2, which is configured to determine the target antenna element to be communicated with the signal processing module 2 based on the signal strength information of the base station signal received by each vibrator in each antenna element.

[0111] The following two specific structures of the selection module 5 are given in the embodiments of this disclosure, and the two selection modules will be described in detail below.

[0112] First Example: Figure 14 is a structural block diagram of a first example of the selection module of this disclosure. As shown in the figure, the selection module 5 includes a plurality of signal coupling units 51, a plurality of signal preprocessing units 52 corresponding one-to-one with the signal coupling units 51, a first selection unit 53, a signal detection unit 54, a control unit 55, and a second selection unit 56;

[0113] Specifically, the signal coupling unit 51 is configured to couple the base station signal received by the corresponding antenna unit to the signal preprocessing unit 52.

[0114] The signal preprocessing unit 52 is configured to preprocess the received signal and transmit it to the first selection unit 53. In some examples, the signal preprocessing unit may include a low-noise signal amplifier, which amplifies the signal to provide good interference immunity. In other examples, the signal preprocessing unit may also include a filter to reduce signal noise and improve signal reliability.

[0115] The first selection unit 53 is configured to, under the control of the processor, sequentially select its connection with the signal preprocessing unit 52, and is configured to transmit a portion of the received signal to the 5G CPE module 3 after selection for user terminal access, and another portion to the signal detection unit 54. It should be noted that because the signal detection unit 54 is only used to analyze the strength of the base station signal and does not need to treat this portion of the signal as a radiated signal, the amount of base station signal transmitted to the signal detection unit is much less than the amount transmitted to the 5G CPE module, preventing energy waste.

[0116] Figure 17 is a schematic diagram of a first selection module provided in an embodiment of this disclosure, and Figure 18 is a schematic diagram of another first selection module provided in an embodiment of this disclosure. In some examples, as shown in Figure 17, the first selection unit 53 may include eight double-pole four-throw (DP4T) switches (only four DP4T switches are schematically shown in the figure), each DP4T switch including two stationary contacts and four moving contacts. The eight DP4T switches include four first DP4T switches (i.e., the four DP4T switches shown in Figure 17) and four second DP4T switches (not shown in Figure 17, but their structure is the same as that of the first DP4T switches). The four first DP4T switches are divided into three first-level first DP4T switches and one second-level first DP4T switch, and the four second DP4T switches are divided into three first-level second DP4T switches and one second-level second DP4T switch.

[0117] Specifically, the four moving contacts of the first-stage first double-pole four-throw switch are each connected to a first oscillator 111. One of the two stationary contacts of the first-stage first double-pole four-throw switch is left floating, and the other is connected to the moving contact of the second-stage first double-pole four-throw switch. Three of the four moving contacts of the second-stage first double-pole four-throw switch are connected to three first-stage first double-pole four-throw switches, and the other moving contact is left floating. One of the two stationary contacts of the second-stage first double-pole four-throw switch is connected to the signal preprocessing unit 52, and the other is connected to the signal detection unit 54.

[0118] The four moving contacts of the first-stage second double-pole four-throw switch are each connected to a second oscillator 112. One of the two stationary contacts of the first-stage second double-pole four-throw switch is left floating, and the other is connected to the moving contact of the second-stage second double-pole four-throw switch. Three of the four moving contacts of the second-stage second double-pole four-throw switch are connected to three first-stage second double-pole four-throw switches, and the other moving contact is left floating. One of the two stationary contacts of the second-stage second double-pole four-throw switch is connected to the signal preprocessing unit 52, and the other is connected to the signal detection unit 54.

[0119] In other examples, as shown in Figure 18, the first selection unit 53 may include six double-pole six-throw (DP6T) switches, each comprising two stationary contacts and six moving contacts. The six DP6T switches are divided into three first-stage DP6T switches and three second-stage DP6T switches. The three first-stage DP6T switches are further divided into two first-level first-stage DP6T switches and one second-level first-stage DP6T switch. The three second-stage DP6T switches are divided into two first-level second-stage DP6T switches and one second-level second-stage DP6T switch.

[0120] Specifically, the six moving contacts of the first-stage first double-pole six-throw switch are each connected to a first oscillator 111, and the two stationary contacts of the first-stage first double-pole six-throw switch are connected to the two moving contacts of the second-stage first double-pole six-throw switch. Four of the six moving contacts of the second-stage first double-pole six-throw switch are connected to two first-stage first double-pole six-throw switches, while the other two moving contacts are left floating. One of the two stationary contacts of the second-stage first double-pole six-throw switch is connected to the signal preprocessing unit 52, and the other is connected to the signal detection unit 54.

[0121] The six moving contacts of the first-stage second double-pole six-throw switch are each connected to a second oscillator 112. The two stationary contacts of the first-stage second double-pole six-throw switch are connected to the two moving contacts of the second-stage second double-pole six-throw switch. Four of the six moving contacts of the second-stage second double-pole six-throw switch are connected to two first-stage second double-pole six-throw switches, while the other two moving contacts are left floating. One of the two stationary contacts of the second-stage second double-pole six-throw switch is connected to the signal preprocessing unit 52, and the other is connected to the signal detection unit 54.

[0122] Compared to a scheme using a double-pole four-throw switch, using a double-pole six-throw switch can reduce the number of switches, lower design complexity, and reduce the failure rate. However, using a double-pole four-throw switch allows for more precise signal control, improving the performance and flexibility of communication equipment. Different choices can be made based on different requirements in practical applications. The signal detection unit 54 is configured to detect the received signal, obtain the signal strength information of the base station signal, and transmit the signal strength information to the control unit 55. In some examples, the signal strength information may include the signal receiving power; a higher signal receiving power indicates better reception of the base station signal.

[0123] The control unit 55 is configured to generate a corresponding control signal and send it to the second selection unit 56 based on the signal strength information of each base station signal it receives. For example, after receiving the signal strength information of each base station signal, the control unit determines the signal with the highest received power and sends a first control signal to the second selection unit.

[0124] The second selection unit 56 is configured to determine the target antenna element based on the control signal and connect it to the 5G CPE module 3. For example, after receiving the first control signal, it determines the antenna element corresponding to the signal with the highest received power as the target antenna element and connects the target antenna element to the 5G CPE module.

[0125] Second example: Figure 15 is a structural block diagram of a second example of the selection module of this disclosure. As shown in Figure 15, the selection module includes multiple signal coupling units 51, a first selection unit 53, a signal preprocessing unit 52, a signal detection unit 54, a control unit 55, and a second selection unit 56.

[0126] Specifically, the signal coupling unit 51 is configured to couple the base station signal received by the antenna unit corresponding to it to the first selection unit 53.

[0127] The first selection unit 53 is configured to, under the control of the processor, sequentially select its connection with the signal coupling unit, and is configured to transmit a portion of the received signal to the signal preprocessing unit 52 and another portion to the 5G CPE module 3 after selection. It should be noted that, because the signal detection unit 52 is only for analyzing the strength of the base station signal and does not need to treat this portion of the signal as a radiated signal, the base station signal transmitted to the signal preprocessing unit 52 is much smaller than the base station signal transmitted to the 5G CPE module 3, to prevent energy waste.

[0128] The signal preprocessing unit 52 is configured to preprocess the received signal and transmit it to the signal detection unit 54. In some examples, the signal preprocessing unit 52 may include a low-noise signal amplifier, which amplifies the signal to provide good anti-interference capability. In other examples, the signal preprocessing unit 52 may also include a filter to reduce signal noise and improve signal reliability.

[0129] The signal detection unit 54 is configured to detect the received signal, acquire signal strength information of the base station signal, and transmit the signal strength information to the control unit 55. In some examples, the signal strength information 54 may include signal receiving power; the higher the signal receiving power, the better it can receive the base station signal.

[0130] The control unit 55 is configured to generate a corresponding control signal and send it to the second selection unit 56 based on the signal strength information of each base station signal it receives. For example, after receiving the signal strength information of each base station signal, the control unit 55 determines the signal with the highest received power and sends a first control signal to the second selection unit 56.

[0131] The second selection unit 56 is configured to determine the target antenna element based on the control signal and connect it to the 5G CPE module communication 3. For example, after receiving the first control signal, it determines the antenna element corresponding to the signal with the highest received power as the target antenna element and connects the target antenna element to the 5G CPE module communication 3.

[0132] It should be noted that the difference between the second example and the first example lies in the relative positions of the first selection unit 53 and the signal preprocessing unit 52. In the second example, the base station signal transmitted through the signal coupling unit 51 first passes through the first selection unit 53 to select the signal with higher received power before amplification and filtering. This can reduce the number of signal amplifiers and filters, thereby reducing costs.

[0133] In other examples, as shown in Figure 16, the first selection unit 53 can also be located between the antenna unit 11 and the isolation module. That is, the selection module 5 can be divided into two parts: the first part includes the signal coupler 51 and the first selection unit 53, and the second part includes the signal preprocessing unit 52, the signal detection unit 54, the control unit 55, and the second selection unit 56. The first part is located between the antenna module 1 and the first isolation module 41, and the second part is located between the first isolation module 41 and the 5GCPE module 3. This arrangement not only reduces the number of amplifiers and filters in the signal preprocessing unit 52, but also reduces the number of first duplexers and first circulators in the first isolation module 41, thereby further reducing costs while maintaining receiver sensitivity.

[0134] The following describes a specific embodiment of antenna module 1, which includes an antenna element 11, and the antenna element 11 is an omnidirectional antenna.

[0135] In this embodiment, antenna element 11 includes at least one first element and at least one second element. Similar to the previous embodiment, the first element operates in the N28 band using FDD (Frequency Division Multiplexing) mode, and the second element operates in the N41 band using TDD (Time Division Multiplexing) mode. Unlike the previous embodiment, both the first and second elements in this embodiment are dual-polarized elements, meaning they can transmit signals with two different polarization directions. For example, the first element transmits horizontally polarized and vertically polarized signals in the N28 band, and the second element transmits horizontally polarized and vertically polarized signals in the N41 band. Of course, the polarization directions of the two signals transmitted by each element can also be ±45°, or other angles; this disclosure does not limit this. It should be noted that the structure of the first element in this embodiment differs from that of the first element 111 described above. The first element in this embodiment can be, for example, a dipole antenna or a Yagi antenna. Similarly, the second element can also be an omnidirectional antenna such as a dipole antenna or a Yagi antenna. This disclosure does not impose any restrictions on this, and therefore this application does not provide specific structural diagrams of the first and second elements.

[0136] Since the first oscillator adopts FDD frequency division multiplexing mode, the uplink signal (i.e., signal from the terminal to the base station) and downlink signal (i.e., signal from the base station to the terminal) can be configured to operate at different frequencies in the communication link between the first oscillator, the first isolation module 41, the signal processing module 2, the second isolation module 42, and the 5G CPE module 3. The uplink signal and downlink signal are separated by the first isolation module 41 and the second isolation module 42. The first isolation module 41 and the second isolation module 42 may, for example, include a duplexer.

[0137] Because the second oscillator adopts a time-division multiplexing (TDD) operating mode, it can control the transmission of uplink and downlink signals at different time periods. Specifically, in this example, the 5G CPE module 3 is also configured to generate a second control signal. The second control signal is a periodic signal, and its high or low level can control which of the uplink and downlink signals can be transmitted in the communication link.

[0138] Specifically, in the communication link between the second oscillator, the first isolation module 41, the signal processing module 2, the second isolation module 42, and the 5G CPE module 3, the signal processing module 2 includes a first signal processing link 21 and a second signal processing link 22, as shown in Figure 19. Uplink signals transmitted from the terminal to the base station are transmitted through the first signal processing link 21, and downlink signals transmitted from the base station to the terminal are transmitted through the second signal processing link 22.

[0139] Further, referring to Figure 19, the communication link consisting of the second oscillator, the first isolation module 41, the signal processing module 2, the second isolation module 42, and the 5G CPE module 3 also includes a third selection unit 61 and a fourth selection unit 62. Specifically, the first end of the third selection unit 61 is connected to the second oscillator via the first isolation module 41, the second end of the third selection unit 61 is connected to the first signal processing link 21, and the third end of the third selection unit 61 is connected to the second signal processing link 22. The fourth end of the fourth selection unit 62 is connected to the first signal processing link 21, the fifth end of the fourth selection unit 62 is connected to the second signal processing link 22, and the sixth end of the fourth selection unit 62 is connected to the second isolation module 42.

[0140] The third selection unit 61 is configured to, in response to the second control signal, select one of the second oscillator and the first signal processing link 21 and the second signal processing link 22 for connection. The fourth selection unit 62 is configured to, in response to the second control signal, select one of the second isolation module and the first signal processing link 21 and the second signal processing link 22 for connection. That is, under the control of the second control signal, the communication link consisting of the second oscillator, the first isolation module 41, the signal processing module 2, the second isolation module 42, and the 5G CPE module 3 periodically transmits uplink and downlink signals to achieve a time-division duplex working mode. In some specific embodiments, the third selection unit 61 and the fourth selection unit 62 may, for example, include a single-pole double-throw switch.

[0141] It should be noted that in the above embodiments, the operating frequencies of the horizontally polarized signal and the vertically polarized signal of the N41 band transmitted in the second oscillator are different. Therefore, they can be transmitted through the same communication link and separated by the first isolation module 41 and the second isolation module 42 in the communication link. The first isolation module 41 and the second isolation module 42 may, for example, include a duplexer.

[0142] Of course, the horizontally polarized signal and the vertically polarized signal of the N41 band transmitted in the second oscillator can operate at the same operating frequency. In this case, the horizontally polarized signal and the vertically polarized signal need to be transmitted through two different communication links.

[0143] Specifically, the second oscillator includes a first radiating unit and a second radiating unit. The first radiating unit is used to transmit a first polarization signal, and the second radiating unit is used to transmit a second polarization signal. The polarization directions of the first polarization signal and the second polarization signal are different. For example, the first polarization signal is a horizontal polarization signal, and the second polarization signal is a vertical polarization signal.

[0144] Referring to Figure 20, the signal processing module 2 includes a first signal processing link 21, a second signal processing link 22, a third signal processing link 23, and a fourth signal processing link 24. The first polarization signal in the uplink signal transmitted from the terminal to the base station is transmitted through the first signal processing link 21, and the first polarization signal in the downlink signal transmitted from the base station to the terminal is transmitted through the second signal processing link 22. The second polarization signal in the uplink signal transmitted from the terminal to the base station is transmitted through the third signal processing link 23, and the second polarization signal in the downlink signal transmitted from the base station to the terminal is transmitted through the fourth signal processing link 24.

[0145] Furthermore, continuing to refer to Figure 20, the communication link consisting of the second oscillator, the first isolation module 41, the signal processing module 2, the second isolation module 42, and the 5G CPE module 3 also includes a third selection unit 61, a fourth selection unit 62, a fifth selection unit 63, and a sixth selection unit 64.

[0146] Specifically, the first end of the third selection unit 61 is connected to the first radiation unit via the first isolation module 41; the second end of the third selection unit 61 is connected to the first signal processing link 21; and the third end of the third selection unit 61 is connected to the second signal processing link 22. The fourth end of the fourth selection unit 62 is connected to the first signal processing link 21; the fifth end of the fourth selection unit 62 is connected to the second signal processing link 22; and the sixth end of the fourth selection unit 62 is connected to the second isolation module 42. The seventh end of the fifth selection unit 63 is connected to the second radiation unit via the first isolation module 41; the eighth end of the fifth selection unit 63 is connected to the third signal processing link 23; and the ninth end of the fifth selection unit 63 is connected to the fourth signal processing link 24. The tenth end of the sixth selection unit 64 is connected to the third signal processing link 23; the eleventh end of the sixth selection unit 64 is connected to the fourth signal processing link 24; and the twelfth end of the sixth selection unit 64 is connected to the second isolation module 42.

[0147] Specifically, the third selection unit 61 is configured to, in response to the second control signal, select one of the first radiating unit to connect with either the first signal processing link 21 or the second signal processing link 22. The fourth selection unit 62 is configured to, in response to the second control signal, select one of the first signal processing link 21 or the second signal processing link 22 to connect with the second isolation module. The fifth selection unit 63 is configured to, in response to the second control signal, select one of the second radiating unit to connect with either the third signal processing link 23 or the fourth signal processing link 24. The sixth selection unit 64 is configured to, in response to the second control signal, select one of the third signal processing link 23 or the fourth signal processing link 24 to connect with the second isolation module 42. In other words, under the control of the second control signal, the communication link consisting of the second oscillator, the first isolation module 41, the signal processing module 2, the second isolation module 42, and the 5G CPE module 3 periodically transmits uplink and downlink signals to achieve a time-division duplex working mode. In this system, the horizontal and vertical polarization components in the uplink signal and the horizontal and vertical polarization components in the downlink signal are transmitted separately through different signal processing links in signal processing module 2, and then isolated by the first isolation module 41 and the second isolation module 42. This facilitates the polarization diversity reception of the signal, improves signal quality, and further enhances the anti-interference capability of the communication equipment. Separating the transmission of the horizontal and vertical polarization components can, in some specific embodiments, include, for example, a single-pole double-throw switch in the third selection unit 61 and the fourth selection unit 62. In some examples, the antenna is not limited to the above structure and may also include a transceiver unit, an RF transceiver, a signal amplifier, a power amplifier, and a filtering unit. The transceiver unit may include a baseband and a receiver. The baseband provides signals in at least one frequency band, such as 2G, 3G, 4G, and 5G signals, and transmits signals in at least one frequency band to the RF transceiver. After receiving the signal, the antenna in the communication system can process it through the filtering unit, power amplifier, signal amplifier, and RF transceiver before transmitting it to the receiver in the transceiver unit. The receiver may be, for example, a smart gateway.

[0148] Furthermore, the RF transceiver is connected to the transceiver unit and is used to modulate the signals transmitted by the transceiver unit, or to demodulate the signals received by the antenna before transmitting them to the transceiver unit. Specifically, the RF transceiver may include a transmitting circuit, a receiving circuit, a modulation circuit, and a demodulation circuit. After the transmitting circuit receives various types of signals provided by the baseband, the modulation circuit can modulate these signals before sending them to the antenna. The antenna receives the signals and transmits them to the receiving circuit of the RF transceiver. The receiving circuit then transmits the signals to the demodulation circuit, which demodulates the signals before transmitting them to the receiving end.

[0149] Furthermore, the RF transceiver is connected to a signal amplifier and a power amplifier, which are then connected to a filtering unit. The filtering unit is connected to at least one antenna. During signal transmission in the communication system, the signal amplifier improves the signal-to-noise ratio (SNR) of the RF transceiver's output signal before transmitting it to the filtering unit; the power amplifier amplifies the power of the RF transceiver's output signal before transmitting it to the filtering unit. The filtering unit may specifically include a duplexer and a filtering circuit. The filtering unit combines the signals output from the signal amplifier and power amplifier, filters out clutter, and transmits them to the antenna, which then radiates the signal. During signal reception in the communication system, the antenna receives the signal and transmits it to the filtering unit. The filtering unit filters out clutter from the received signal and transmits it to the signal amplifier and power amplifier. The signal amplifier increases the gain of the received signal, improving the SNR; the power amplifier amplifies the power of the received signal. The signal received by the antenna, after processing by the power amplifier and signal amplifier, is transmitted to the RF transceiver, which then transmits it to the transceiver unit.

[0150] In some examples, the signal amplifier may include various types of signal amplifiers, such as low-noise amplifiers, without limitation.

[0151] In some examples, the antenna provided in this disclosure also includes a power management unit connected to a power amplifier to provide voltage to the power amplifier for amplifying signals.
