[0029] In order to make the purposes, technical solutions, and advantages of the embodiments of the present disclosure clearer, the following will be combined with the accompanying drawings of the embodiments of the present disclosure to make a clear and complete description of the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. The components of the embodiments of the present disclosure generally described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present disclosure provided in the accompanying drawings is not intended to limit the scope of the claimed present disclosure, but only represents selected embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present disclosure.

[0030] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0031] The term "a plurality of" in the embodiments of the present disclosure refers to two or more, and other quantifiers are similar. The term "and / or" in the embodiments of the present disclosure describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can mean that there are three cases of A alone, A and B together, and B alone. The character " / " generally represents that the associated objects before and after it are in an "or" relationship. In addition, the term "at least one" in this paper means any one of a plurality of or any combination of at least two of a plurality of, for example, including at least one of A, B, and C, which can mean including any one or more elements selected from the set consisting of A, B, and C.

[0032] The terms "first", "second", "third", "fourth", "1", "2", and the like (if any) in the specification and claims of the present application and the above-described drawings are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that shown or described.

[0033] In the 5G era, with the increase of communication frequency and the shortening of signal radiation distance, the size of the antenna is gradually reduced, and higher requirements are put forward for the radiation distance and gain of the antenna. Large-scale array antenna equipment emerges as the times require, and for the multi-vibrator design of array antenna equipment, dual-polarized antenna can better meet the three-dimensional space radiation distance requirement, and is realized through left-handed, right-handed, vertical and horizontal polarization modes. The current array antenna equipment antenna is connected with two independent radio frequency links in the hardware design, and corresponds to +45° and -45° two pairs of polarization directions orthogonal to each other. The dual-polarized antenna can work in the transceiver duplex mode at the same time. The dual-polarized antenna can save the number of single directional antennas, reduce the wind area and the volume of the equipment, and thus has been widely applied.

[0034] With the development of communication technology, into the 6G era, the sense of integration technology has become the core vision of 6G. Research shows that for the sense of integration equipment, in the case of different antennas for sensing reception and sensing transmission, the scheme of dual-polarized antenna for sensing reception has no obvious advantage in terms of antenna gain, target coverage angle, etc., and in the case of the same number of channels and the same index requirements, the vertical resolution of the dual-polarized array antenna scheme is poor, and the design complexity of the dual-polarized array antenna is also high. Therefore, how to simplify the design of the sensing reception antenna of the sense of integration equipment and improve the reception performance of the sensing reception antenna of the sense of integration equipment is a technical problem to be solved.

[0035] Based on the above research, the present disclosure provides a sensing reception antenna device, a sense of integration equipment and a network system. The sensing reception antenna device in the sense of integration equipment includes at least one digital channel and a plurality of antenna units. Each digital channel is connected with the same number of antenna units, and each antenna unit includes a single-polarized antenna vibrator. Compared with the design scheme of dual-polarized antenna, the design difficulty and cost of the antenna array can be reduced, and the sensing reception performance of the antenna can be improved.

[0036] The technical solutions in the embodiments of the present disclosure will be described clearly and completely in combination with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present disclosure.

[0037] Referring to Figure 1As shown, it is a schematic diagram of an architecture of a network system provided by an embodiment of the present disclosure. The network system 1000 includes a communication and sensing integrated device 100, a sensing target 200, and an electronic device 300. The sensing target 200 and the electronic device 300 can communicate with the communication and sensing integrated device 100 through a communication network.

[0038] Among them, the communication and sensing integrated device 100 refers to a device using the communication and sensing integrated technology, and the communication and sensing integrated technology refers to the unified design of communication and sensing functions. Through the joint design of air interface and protocol, time-frequency-space resource multiplexing, hardware device sharing and other means, the wireless network can realize high-precision and fine sensing functions while realizing high-quality communication interaction, and improve the overall performance and service capability of the network.

[0039] It should be noted that the sensing target 200 and the electronic device 300 can be the same or different. For example, the sensing target 200 can be a drone or a low-altitude aircraft, and the electronic device 300 can be a user terminal. Of course, the sensing target 200 and the electronic device 300 can both be user terminals or both be drones.

[0040] It can be understood that the above-mentioned user terminal and drone are only examples. In the case of application of the network system 1000 in different scenarios, the sensing target 200 and the electronic device 300 can be devices in different application scenarios, for example, any object that can reflect sensing signals can be called a sensing target. Among them, the application scenarios include but are not limited to low-altitude security, intelligent transportation, smart home, intelligent medical care and other scenarios.

[0041] In some embodiments, the network system 1000 can include various communication systems. For example, the applicable communication system can be a long term evolution (LTE) system, an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD) system, a long term evolution advanced (LTE-A) system, a universal mobile system (UMTS), a worldwide interoperability for microwave access (WiMAX) system, a 5G new radio (NR) system, and an evolved communication system thereof. The various systems can include terminal devices and network devices. The system can also include a core network part, such as an evolved packet system (EPS), a 5G system (5GS), and the like. The above systems can include multiple networks.

[0042] That is, in this embodiment, the network device 100 can be the network device, the perception target 200 and the electronic device 300 can be referred to as terminal devices.

[0043] For example, the terminal device can be a device that provides voice and / or data connectivity to a user, a handheld device having a wireless connection function, or another processing device connected to a wireless modem, and the like. In different systems, the name of the terminal device can also be different, for example, in the 5G system, the terminal device can be referred to as a user equipment (UE).

[0044] The wireless terminal device can be a USB storage device, other personal computer memory device, and a dongle, and can communicate with one or more core networks (CN) via a radio access network (RAN). The wireless terminal device can be a mobile terminal device, such as a mobile telephone (also known as a "cellular" telephone) and a computer with a mobile terminal device, e.g., a portable, pocket, hand-held, computer-embedded, or car-mounted mobile device which exchanges language and / or data with a radio access network. For example, a personal communication service (PCS) telephone, a cordless telephone, a session initiated protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a personal computer, a tablet computer, a machine-type communication (MTC) terminal device, and the like.

[0045] The wireless terminal device can also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, and a wireless access router and modem that meet the limitations of the present definition, and the like. The embodiments of the present disclosure are not limited.

[0046] The network device involved in the embodiments of the present disclosure can include a base station. The base station can include a plurality of cells that provide services for terminals. According to different application scenarios, the base station can also be referred to as an access point, or can be a device in an access network that communicates with a wireless terminal device through one or more sectors over an air interface, or other names.

[0047] The network device can be used to exchange received air frames and Internet Protocol (IP) packets as a router between a wireless terminal device and the rest of an access network, which can include an Internet Protocol (IP) communication network.

[0048] The network device can also coordinate management of properties of the air interface. For example, the network device according to the embodiments of the present disclosure can be an evolved network device (eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station (gNB) in a 5G network architecture, and the like, and can also be a home evolved Node B (HeNB), a relay node, a femto, a pico, a network test device, a satellite base station, and the like, and is not limited in the embodiments of the present disclosure. In some network structures, the network device can include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit can also be arranged geographically apart.

[0049] Referring to Figure 2 As shown in the figure, a structure schematic diagram of a sensing-integrated device 100 provided by the embodiments of the present disclosure is shown. As Figure 2 As shown in the figure, the sensing-integrated device 100 includes a sensing receiving antenna device 10, a sensing transmitting antenna device 20, and a communication transceiving antenna device 30. The sensing transmitting antenna device 20 is configured to transmit a sensing signal to a sensing target 200, and the sensing receiving antenna device 10 is configured to receive a sensing signal reflected by the sensing target 200, which is used to realize detection of the sensing target 200. The communication transceiving antenna device 30 is configured to transceive a communication signal with an electronic device 300. It can be understood that the communication transceiving antenna device 30 can be realized by the same antenna device, or can be realized by different antenna devices.

[0050] In some embodiments, the sensing transmitting antenna device 20 and the communication transceiving antenna device 30 are the same antenna device, that is, the same antenna device can realize the functions of transceiving a communication signal and transmitting a sensing signal, so that the space occupied by the antenna can be reduced, and thus the volume of the sensing-integrated device 100 can be reduced.

[0051] Of course, in other embodiments, the sensing transmitting antenna device 20 and the communication transceiving antenna device 30 can also be realized by different antenna devices.

[0052] Exemplarily, the sensing transmitting antenna device 20 and the communication transceiving antenna device 30 are realized by dual-polarized array antennas. In this way, the number of antennas of a single directional antenna can be saved, and the wind area and the volume of the device can be reduced.

[0053] In the embodiment of the present disclosure, for the sensing integrated device 100, the sensing receiving antenna device 10 is designed independently of the sensing transmitting antenna device 20 and the communication transceiving antenna device 30, so that the sensing receiving antenna device 10 only needs to realize the reception of sensing signals and does not need to perform the transceiving service of communication signals. Therefore, the sensing receiving antenna device 10 can be designed according to actual needs to improve the receiving performance of the antenna.

[0054] The sensing receiving antenna device 10 provided by the embodiment of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0055] Please refer to Figure 3 and Figure 4 , wherein, Figure 3 is a principle block diagram of a sensing receiving antenna device provided by the embodiment of the present disclosure, Figure 4 is a structure schematic diagram of a sensing receiving antenna device provided by the embodiment of the present disclosure. The sensing receiving antenna device 10 includes at least one digital channel 11 and a plurality of antenna units 12. Each digital channel 11 is connected to the same number of antenna units 12, and each antenna unit includes a single-polarized antenna element.

[0056] In the embodiment of the present disclosure, the single-polarized antenna element is a vertical single-polarized antenna element. When the number of digital channels 11 is multiple, the multiple digital channels 11 are arranged in the vertical direction in sequence.

[0057] The following takes two digital channels as an example to describe the schemes of using single-polarized antennas and dual-polarized antennas in the sensing receiving antenna device 10.

[0058] As shown in Figure 4 , the number of antenna units 12 is six, and each digital channel 11 is connected to three single-polarized antenna units 12 through a 1-to-3 power combiner. In this embodiment, every three single-polarized antenna elements correspond to one digital channel 11, and six single-polarized antenna elements realize one beam in the horizontal direction and two beams in the vertical direction.

[0059] Referring to Figure 5 , if dual-polarized antennas are used, two digital channels are connected to six dual-polarized (±45° polarization) antenna units through a 1-to-6 power combiner. In this scheme, six elements in two polarization directions correspond to one digital channel, and six dual-polarized antenna units realize one dual-polarized beam in the horizontal direction and one beam in the vertical direction.

[0060] Firstly, compared with the scheme of using dual-polarized antennas in Figure 5 , Figure 4The scheme using a single-polarized antenna increases the number of channels in the vertical direction, resulting in a doubling of the number of vertical beams. This increases the flexibility of the beams in the vertical direction, making the vertical shaping of the antenna array more flexible and the vertical coverage angle larger.

[0061] Secondly, regarding Figure 4 In the solution employing a single-polarized antenna, the scanning capability of the single-polarized antenna can be improved by adjusting the digital channel of the dual-polarized scheme to the vertical direction. Furthermore, in terms of beam scanning capability, the increased number of digital channels in the vertical direction allows for a wider vertical spacing between adjacent antennas, thereby increasing the antenna aperture, improving antenna gain, narrowing the beamwidth, and enhancing the resolution of the vertical beam.

[0062] Secondly, regarding Figure 4 The scheme using a single-polarized antenna is superior to... Figure 5 The scheme using dual-polarized antennas employs fewer stages of power combiner (reducing the number of stages from a one-to-six power combiner to a one-to-three power combiner), which simplifies the design of the power grid and improves antenna performance.

[0063] Specifically, see Figure 6 The diagram shown is a schematic representation of another sensing and receiving antenna device provided in an embodiment of this disclosure. The sensing and receiving antenna device 10 further includes at least one power combiner 13 and at least one phase shifter 14. The antenna elements 12 connected to each digital channel 11 are arranged in a first array. At least one target row antenna element in the first array is equipped with a phase shifter 14, and each antenna element 12 in the target row is connected to its corresponding phase shifter 14. Each row antenna element in the first array is connected to the digital channel 11 through a power combiner 13.

[0064] Specifically, depending on actual needs, a phase shifter 14 can be provided in each row of antenna elements, or a phase shifter 14 can be provided in some row of antenna elements. The row of antenna elements with phase shifters 14 is the target row antenna element. In addition, there is no limit to the number of phase shifters 14 provided for any target row. For example, one phase shifter 14 can be provided for each target row, or multiple phase shifters 14 can be provided for each target row. There is no specific limitation.

[0065] Furthermore, each antenna element 11 in the target row antenna element can be connected to the digital channel 11 via a corresponding phase shifter 14.

[0066] This embodiment is a schematic diagram of a single digital channel, specifically with one vertical row of antenna elements 'a' and one horizontal row of antenna elements 'b'. That is, one power combiner 13 corresponds to 'a' rows of antenna elements 12, and each row includes 'b' antenna elements 12. Here, 'a' and 'b' are both positive integers greater than or equal to 1.

[0067] In some embodiments, when the number of digital channels 11 is multiple, the multiple digital channels are arranged in a second array. As shown, if the sensing receiving antenna device 10 includes m*n digital channels, a single polarization array design with m vertical rows and n horizontal columns can be used, and if the array of each digital channel uses the scheme as shown in FIG. 2, there are a total of m*a*n*b single polarization antenna elements. Here, m and n are both positive integers greater than or equal to 1. Figure 7 Figure 6

[0068] For the same digital channel device, to achieve the same antenna gain and pointing requirements, if a dual polarization antenna array is used, a dual polarization array design with m / 2 vertical rows and n columns can be used, and a dual polarization array design with 2a vertical rows and b horizontal columns is used for the sensing receiving antenna array, and there are a total of 2*m*a*n*b antenna elements. At this time, in the vertical direction, the single polarization antenna array can realize m beams, while the dual polarization array antenna scheme can only realize m / 2 beams.

[0069] In the embodiments of the present disclosure, since the single polarization antenna scheme is used, when the sensing receiving antenna device 10 performs beam control through the phase shift switching circuit, the number of phase shift switching circuits is reduced, thereby reducing the cost of the device. In addition, due to the reduction of the distribution stages of the power combiner and the reduction of the phase shift switching circuit, the design complexity is also reduced, and the design difficulty of the printed circuit board (PCB) is also reduced.

[0070] The phase shift switching circuit includes a radio frequency switch and a plurality of angle phase shifters, and by switching different phase shifters, the antenna beam pointing can be controlled.

[0071] The sensing receiving antenna device, the sensing and communication integrated device, and the network system provided by the embodiments of the present disclosure can reduce the design difficulty and cost of the antenna array, and improve the sensing receiving performance of the antenna from multiple angles.

[0072] The following will take a 64-channel digital channel as an example to describe the single polarization antenna array design scheme and the dual polarization array antenna design scheme.

[0073] ​​When using a single-polarized array antenna, a design with 4 rows vertically and 16 columns horizontally can be adopted. If the corresponding sensing and receiving antenna array adopts a single-polarized array antenna design with one vertical support for three and one horizontal support for one, a total of 192 antenna elements are required. However, when using a dual-polarized array antenna, for 64 digital channels, a design with 2 rows vertically and 16 columns horizontally can be adopted. If the corresponding sensing and receiving antenna array adopts a dual-polarized array antenna design with one vertical support for six and one horizontal support for one, a total of 384 antenna elements are required. Thus, the single-polarized antenna array design can achieve four beams in the vertical direction, while the dual-polarized array antenna design can only achieve two beams.

[0074] See Figure 8 As shown, for the single-polarization array antenna design scheme, since it can support three antennas in the vertical direction, resulting in four channels in the vertical direction, for the 12 antenna elements in the vertical direction, when the vertical beam satisfies the requirement of covering an upward tilt of 34°, the 3dB co-polarization bandwidth of the single-polarization array antenna in the vertical 34-degree direction is 7.5101°. Figure 8 As shown in α), the 3dB starting angle = -34.6335° and the 3dB ending angle = -27.1234°.

[0075] See Figure 9 As shown, for the dual-polarized array antenna design scheme, since it is a one-to-six configuration with two channels in the vertical direction, for the 12 antenna elements in the vertical direction, when the vertical beam satisfies the coverage at an upward tilt of 34°, the 3dB co-polarized bandwidth of the dual-polarized array antenna in the vertical 34-degree direction is 8.3316°. Figure 9 (As shown in β), the 3dB starting angle is -34.7155°3dB, and the ending angle is -26.3839°.

[0076] The above analysis shows that by using a single-polarized array antenna scheme and moving the digital channel of the dual-polarized array antenna to the vertical direction, the vertical scanning capability of the single-polarized array antenna can be improved, and the side lobe to the right of the main lobe of the single-polarized array antenna is lower (see...). Figure 8 ).

[0077] In addition, modeling can be performed separately for the two design schemes mentioned above. Algorithm simulation can be conducted by simulating the application scenario of sensing and receiving. The specific simulation parameters are shown in Table 1 below:

[0078] Table 1

[0079]

[0080]

[0081] Specifically, the simulation results are as follows: Figure 10As shown, GOB (Grid of Beam) is a high-speed scanning algorithm. Figure 10 Curve S1 in the simulation represents the error curve of the design scheme using a single-polarized array antenna, while curve S2 represents the error curve of the design scheme using a dual-polarized array antenna. The simulation results show that the single-polarized array antenna design reduces the angle estimation error in the vertical dimension and improves the antenna's receiving performance.
