[0002] This application claims priority to Chinese Patent Application No. 202411979561.0, filed on December 27, 2024, entitled "A Radiating Structure, Antenna and Communication Device", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of communication technology, and in particular to a radiating structure, antenna, and communication device. Background Technology

[0004] An antenna mainly consists of components such as a radiator and a feed line. The radiator, as the primary component, is mainly used for the radiation and reception of electromagnetic waves. The radiator is connected to the feed line, which transmits radio frequency signals to the radiator, enabling it to radiate electromagnetic waves. Additionally, the radiator can also transmit received electromagnetic waves from the outside world to the feed line, thus enabling the transmission and reception of wireless signals.

[0005] The structure of the radiator has a significant impact on the signal coverage of the antenna. How to make the structure of the radiator better meet communication requirements is a current research hotspot. Summary of the Invention

[0006] This application provides a simple, safe, and omnidirectional radiating structure, antenna, and communication device.

[0007] Firstly, this application provides a radiating structure. The radiating structure includes a first radiator, a second radiator, a feed element, and a ground element. The first and second radiators are connected, a first end of the feed element is connected to the connection point between the first and second radiators, and a first end of the ground element is connected to the connection point. In this way, when the radiating structure is used in an antenna for communication, the transverse currents between the two radiators can be partially or completely canceled out. This radiating structure reduces the radiation intensity of the antenna within the 0° to ±θ angle range, thereby alleviating radiation safety issues within this range. Furthermore, since radiation within the 0° to ±θ angle range reduces the radiation intensity within the +θ to +θ1 and -θ to -θ1 angle ranges, where θ is less than θ1, the partial or complete cancellation of the transverse currents between the two radiators is beneficial for improving the radiation gain within the +θ to +θ1 and -θ to -θ1 angle ranges. Therefore, when operating at the same power level, an antenna with a radiating structure exhibits lower radiated energy in the 0° to ±θ1 angular range, and higher radiated energy in the +θ to +θ1 and -θ to -θ1 angular ranges, thus achieving a wider radiation range and greater safety. The partial or complete cancellation of the transverse currents between two radiators can also be understood as the energy radiated by the transverse currents of the two radiators, due to their different directions, partially or completely cancels each other out after superposition.

[0008] In one example, the connection point can be a point, or it can be a line, curve, or other possible form of line. Alternatively, the connection point can be a sheet-like region or surface with a certain shape and area. Or, the connection point can be other three-dimensional structures. The entire area of ​​the connection point can be considered to belong to either the first radiator or the second radiator. Alternatively, a portion of the connection point can be considered to belong to the first radiator, and another portion can be considered to belong to the second radiator. Alternatively, at least a portion of the connection point can be considered independent of both the first and second radiators.

[0009] In one example, the connection includes a connector. Optionally, all areas of the connection can be the connector, in which case the connector can be considered part of the connection. Alternatively, the connector can be a part of the connection. When the connector is part of the connection, the first end of the feed body or the first end of the ground body can be connected to the connector, or the first end of the feed body or the first end of the ground body can be connected to other areas of the connection. In this case, when other parts of the connection besides the connector are connected to the first radiator and / or the second radiator, these other parts can be considered as structures independent of the first radiator and / or the second radiator, or these other parts can be considered as part of the first radiator and / or the second radiator in close proximity. When the connection includes a connector, the connection can provide sufficient area or surface area to connect to the feed body and the ground body. This improves the ease of fabrication of the radiator structure.

[0010] In one example, the first radiator and the second radiator can be located in the same plane. This helps to improve the ease of fabrication of the radiating structure, and also facilitates the mutual attenuation of the transverse currents in the first radiator and the second radiator.

[0011] Optionally, the connection point and the first radiator can be located in the same plane. That is, both the first and second radiators can be located in the same plane. This helps to improve the ease of fabrication of the radiating structure, and also facilitates the mutual attenuation of the transverse current in the first and second radiators.

[0012] Alternatively, the plane where the connection is located forms a first angle with the plane where the first radiator is located. This structure offers good flexibility.

[0013] In one example, the plane containing the first radiator and the plane containing the second radiator are parallel to each other. This structure offers good manufacturing flexibility.

[0014] Optionally, the surface where the connection is located can form a first angle with the plane where the first radiator is located. This structure offers good manufacturing flexibility.

[0015] Optionally, the surface where the connection is located can be parallel to the plane where the first radiator is located. This structure offers good manufacturing flexibility.

[0016] Specifically, the first included angle can be any other angle such as 90°, 89°, or 70°, which provides good structural flexibility during manufacturing.

[0017] In one example, the first end of the feed electrode and the first end of the ground electrode are connected on the same side of the connection. The second end of the feed electrode and the second end of the ground electrode extend in the same direction, away from the connection. This improves the ease of connection of the radiating structure to the floor.

[0018] In one example, the first end of the feed electrode and the first end of the ground electrode are symmetrical about a first point in the connection. This structure ensures that the paths of the radio frequency signals in the feed and ground electrodes as they flow through the connection are symmetrical. Therefore, it increases the amount of lateral current that cancels out each other in the connection, reducing the amount of normal radiation generated by the connection and thus reducing the degradation of the antenna's radiation performance. The first point can be, for example, the geometric center, center point, centroid, or other possible point of the connection. This first point can be a physically existing point, a theoretical geometric point, or another type of point.

[0019] In one example, the first and second radiators are symmetrical about the junction. This example can further increase the amount by which the transverse currents in the two radiators cancel each other out. When this structure is used in an antenna for communication, it can further reduce the radiation intensity in the antenna's 0° to ±θ angle range and further increase the radiation gain in the +θ to +θ1 angle range and -θ to -θ1 angle range, thus achieving a wider radiation range and greater security.

[0020] In one example, the symmetry between the first and second radiators about the junction includes: the first and second radiators being symmetric about a second point in the junction. This second point can be the geometric center, central point, centroid, or other possible point of the junction. This second point can be a physically existing point, a theoretical geometric point, or another type of point.

[0021] In one example, the first and second points mentioned above can be the same point at the connection, or they can be different points.

[0022] In one example, the symmetry between the first radiator and the second radiator about a second point at the junction includes rotational symmetry or 180° symmetry between the first radiator and the second radiator about the second point at the junction.

[0023] In one example, the symmetry of the first radiator and the second radiator about the junction includes: the first radiator and the second radiator being mirror-symmetric about a first line in the junction.

[0024] In one example, the first line may specifically be one of a plurality of lines passing through the connection point. The location where the first line passes through the connection point can be any location. Alternatively, the first line may also be at least one of a plurality of lines passing through the second point.

[0025] In one example, the first line is the central axis of the connection. This central axis refers to the line of symmetry of the connection itself; that is, the connection is symmetrical about this central axis. In some cases, this central axis may or may not pass through the second point.

[0026] In one example, the radial structure is a single, integral piece, or molded as a single unit. This design facilitates easier manufacturing, thereby reducing production costs.

[0027] Secondly, this application provides an antenna, which includes a ground plane and any of the aforementioned radiating structures.

[0028] In one example, both the first radiator and the second radiator are coupled to the ground plane. In other words, the first radiator and the ground plane form a capacitive structure, and the second radiator and the ground plane also form a capacitive structure.

[0029] In one example, the antenna may further include a feed network comprising a feed line and a ground line. The feed line is connected to a second end of a feed body, and both the ground line and the ground body are connected to a ground plane. The feed network may include at least one of the following devices: a phase shifter, a filter, etc.

[0030] Thirdly, this application also provides a communication device including the antenna described in the second aspect. By configuring this antenna in the communication device, the communication device can have a wider radiation range and be more secure.

[0031] In one example, the communication device may include radio frequency (RF) circuitry. This RF circuitry can be connected to the ground plane and the feed element in the radiating structure of the antenna to transmit RF signals to the antenna. Alternatively, when the antenna is equipped with a feed network, the RF circuitry can be connected to the ground plane and the feed element in the radiating structure of the antenna via the feed network.

[0064] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0065] To facilitate understanding of the radiation structure provided in the embodiments of this application, its application scenarios will be introduced first below.

[0066] The radiating structure provided in this application embodiment can be used in an antenna. This antenna can be applied to various possible communication devices or systems. For example, it can be used in a microwave system. As another example, it can be used in a radio access network (RAN).

[0067] A radio access network (RAN) includes at least one RAN node of a different type, such as a radio relay device and / or a radio backhaul device. Terminals connect to the RAN node wirelessly. The RAN can be a 3rd Generation Partnership Project (3GPP) related cellular system, such as the 4th generation (4G) (also understood as Long Term Evolution, LTE), the 5th generation (5G) (also understood as New Radio, NR), or a future-oriented evolution system. The RAN can also be an open RAN (O-RAN or ORAN), a cloud radio access network (C-RAN), or a wireless fidelity (WiFi) system. Furthermore, the RAN can be a communication system that integrates two or more of the above systems.

[0068] The aforementioned radiating structures or antennas can be applied to RAN nodes or terminals. RAN nodes, sometimes also called access network equipment, RAN entities, or access nodes, constitute part of the communication system and help terminals achieve wireless access. Multiple RAN nodes in a communication system can be of the same type or different types. In some scenarios, the roles of RAN nodes and terminals are relative. For example, a network element in a communication system can be a helicopter or a drone, which can be configured as a mobile base station. For terminals accessing the wireless access network through this network element, the network element is a base station; but for the base station, the network element is a terminal. RAN nodes and terminals are sometimes both referred to as communication devices.

[0069] In one possible scenario, a RAN node can be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next-generation NodeB (gNB), a base station in a future mobile communication system, or an access node in a WiFi system. A RAN node can be a macro base station, a micro base station or indoor station, a relay node or donor node, an access site for a local area network in an optical network, or a radio controller in a C-RAN scenario. Optionally, a RAN node can also be a server, wearable device, vehicle, or in-vehicle equipment. For example, the access network equipment in vehicle-to-everything (V2X) technology can be a roadside unit (RSU).

[0070] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, with each RAN node performing some of the functions of a base station. For example, a RAN node could be a module integrating a wireless fidelity (Wi-Fi) antenna, such as a router or other module capable of 360° omnidirectional coverage. Another example is a RAN node radio unit (RU). An RU can be included in radio frequency equipment or units, such as a pico radio remote unit (pRRU), a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0071] In this application, the terminal can also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, smart cities, etc. Terminals can be mobile phones, tablets, computers with wireless transceiver capabilities, wearable devices, vehicles, drones, helicopters, airplanes, ships, robots, robotic arms, smart home devices, etc. The embodiments of this application do not limit the device form of the terminal.

[0072] The radiating structure provided in the embodiments of this application can be used to realize wireless signal transmission between different terminals, as well as wireless signal transmission between a base station and a terminal. In summary, the radiating structure provided in the embodiments of this application can be applied to a variety of communication devices with wireless signal transmission requirements.

[0073] Figure 1 illustrates an example of an indoor small base station antenna. The antenna of this indoor small base station is installed at a high point indoors, such as in a suspended ceiling or roof. Ideally, the antenna's radiation direction should be towards the ground, with a radiation pattern resembling an inverted umbrella, to achieve effective wireless signal coverage indoors. The type (or specific design) of the radiating structure incorporated into the antenna significantly impacts its radiation range and radiation safety.

[0074] For example, Figure 2 shows a radiating structure 012 that can be applied in an antenna, specifically a planar inverted F antenna (PIFA). The radiating structure 012 includes a radiator 0121, a ground wire 0122, and a feed wire 0123. One end of the ground wire 0122 is connected to the edge of the radiator 0121. One end of the feed wire 0123 is connected to any region of the radiator 0121. In the example provided in Figure 2, one end of the feed wire 0123 is connected to the central region of the edge of the radiator 0121.

[0075] As shown in Figures 3 and 4, an antenna 01 employing the radiating structure 012 shown in Figure 2 is illustrated. The antenna 01 includes the radiating structure 012 and a ground plane 011. The radiating structure 012 can transmit or receive electromagnetic waves (also referred to as wireless signals). The ground plane 011 can also be referred to as a base plate or reflector. The ground plane 011 can effectively reflect the wireless signals generated by the radiating structure 012. Additionally, in the examples provided in Figures 3 and 4, for the purpose of illustrating the feeding of the radiating structure 012, the antenna 01 also includes a radio frequency (RF) circuit 013. In some other examples, the antenna 01 may not include the RF circuit 013. In this case, the antenna 01 and the RF circuit 013 can be independent structures that can be used together.

[0076] In this embodiment, the radio frequency circuit 013 is used to send radio frequency signals to the radiating structure 012 so that the radiating structure 012 radiates electromagnetic waves outward. In some examples, the radio frequency circuit 013 may include at least one of the following devices: modulator, oscillator, mixer, filter, or power amplifier. This application does not limit the specific type of device included in the radio frequency circuit 013.

[0077] As shown in Figures 3 and 4, the radiator 0121 is located on one side of the floor 011, and the radiator 0121 is coupled to the floor 011, forming a capacitive structure. One end of the ground wire 0122 is connected to the radiator 0121, and the other end is connected to the floor 011. One end of the feed wire 0123 is connected to the radiator 0121, and the other end is connected to the radio frequency circuit 013. It should be noted that the radio frequency circuit 013 includes a feed port and a ground port. Specifically, the feed port of the radio frequency circuit 013 is connected to one end of the feed wire 0123 via transmission line 014. The ground port of the radio frequency circuit 013 is connected to the floor 011 via transmission line 015.

[0078] When the radiating structure 012 is applied to the antenna 01, the electromagnetic waves radiated by the structure formed by the radiating structure 012 and the ground plane 011 have good omnidirectionality in a plane parallel to the ground plane 011, enabling wide-area wireless signal coverage. Therefore, by configuring the radiator 0121 in the antenna 01 of the base station, the antenna's wireless signal can achieve effective 360° spatial coverage, effectively reducing signal coverage blind spots.

[0079] For example, as shown in Figure 4, the dashed line in Figure 4 illustrates the approximate radiation pattern of the wireless signal from antenna 01. That is, the wireless signal from antenna 01 can achieve effective 360° coverage in space. As shown in Figure 1, when the antenna shown in Figure 3 or 4 is installed on a ceiling or roof, the antenna's radiation direction is towards the ground, and the shape of the signal's radiation range resembles an inverted umbrella, thus achieving effective wireless signal coverage within the room.

[0080] However, as shown in Figure 3, in practical applications, a transverse current will inevitably exist in the radiator 0121 (as indicated by the dashed arrow in Figure 3). Based on the principle of electromagnetic induction, this transverse current will cause the antenna 01 to generate normal radiation. Here, normal refers to the direction perpendicular to the radiator 0121 or the ground 011.

[0081] Referring to the example shown in Figure 1, the floor 011 of antenna 01 is installed near the ceiling, while the radiating structure 012 is positioned further away from the ceiling than the floor 011. To ensure signal coverage and prevent blind spots, the antenna typically has high power. Since antenna 01 also radiates in the normal direction, it generates high radiated energy in that direction as well. As shown in Figure 1, the antenna exhibits strong signal radiation within an angle range of 0° to ±θ relative to the normal. Here, θ is greater than 0° and less than 90°. For example, θ can be 30°, 45°, or other values ​​without restriction. When the signal radiation within this θ angle range is high, there is a radiation safety hazard. Furthermore, this normal radiation narrows the horizontal radiation range, thus weakening the horizontal radiated energy and limiting the coverage area of ​​the antenna's horizontal signal. In other words, the presence of lateral current weakens the antenna's coverage range.

[0082] Therefore, embodiments of this application provide a radiation structure that facilitates reducing radiation intensity in the normal direction, as well as an antenna and communication device equipped with this radiation structure. This radiation structure enables a safe and larger signal radiation range. For example, taking Figure 1 as an example, within the angle range of 0° to ±θ relative to the normal, the radiated energy is below a certain threshold, which improves the safety of signal radiation. Furthermore, within the angle range of ±θ to ±θ1, the radiated energy is increased, improving communication quality. Here, θ1 is greater than θ, and can be, for example, 75°, 80°, 85°, 89°, etc., and is not limited in this application.

[0083] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0084] This application provides a radiating structure 11, which includes a radiator, a feed element 114, and a grounding element 115. Optionally, the radiator can be considered to include a first radiator 111 and a second radiator 112, which are connected together. The first end of the feed element 114 is connected to a connection point 113 between the first radiator 111 and the second radiator 112, and the first end of the grounding element 115 is connected to this connection point 113. For example, Figures 5 to 17 and Figures 20 to 23 show example diagrams of the radiating structure 11 provided in this application.

[0085] The first radiator 111 and the second radiator 112 can also be referred to as a capacitor-loaded structure or a top-loaded structure.

[0086] In the radiating structure 11, both the feed body 114 and the ground body 115 are connected between the first radiator 111 and the second radiator 112. In this way, when the radiating structure 11 is used in an antenna for communication, the lateral currents between the two radiators can be partially or completely canceled out, thereby reducing the radiation intensity in the antenna normal direction within the 0° to ±θ angle range shown in Figure 1, thus alleviating the radiation safety issue in the normal direction. Furthermore, as mentioned earlier, normal radiation narrows the horizontal radiation range, thus weakening the horizontal radiation energy to some extent. Therefore, by canceling out the lateral currents to a certain extent through the radiating structure 11, it is beneficial to improve the horizontal radiation gain within the ±θ to ±θ1 angle range shown in Figure 1, thereby improving communication quality. Therefore, when operating at the same power level, the radiating structure shown in this embodiment can provide safer and more reliable communication.

[0087] The partial or complete cancellation of the transverse currents between two radiators can also be understood as the energy radiated by the transverse currents of the two radiators being partially or completely canceled out after superposition due to their different directions.

[0088] Figure 6 shows an antenna 10 employing the radiating structure 11 shown in Figure 5. The antenna 10 includes the radiating structure 11 and a ground plane 12. When the antenna is powered on, the antenna 10 is used in conjunction with the radio frequency (RF) circuit 13. The RF circuit 13 may be included in the antenna 10, and may be integrated with the antenna 10 into a single device (or apparatus), or may be a separate device from the antenna 10, without limitation. For example, in the example provided in Figure 7, the RF circuit 13 is also shown in the antenna 10. Alternatively, Figure 7 can also be viewed as an example diagram of the antenna 10 and the RF circuit 13 being used in conjunction.

[0089] In this embodiment, the radio frequency circuit 13 is used to send radio frequency signals to the radiating structure 11 so that the radiating structure 11 radiates electromagnetic waves outward. In some examples, the radio frequency circuit 13 may include at least one of the following devices: modulator, oscillator, mixer, filter, or power amplifier. This application does not limit the specific type of device included in the radio frequency circuit 13.

[0090] As shown in Figure 7, the radiator structure 11 is located on one side of the floor 12. One end of the grounding body 115 (the upper end in Figure 7) is connected to the connection point 113, and the other end (the lower end in Figure 7) is connected to the floor 12. One end of the feed body 114 (the upper end in Figure 7) is connected to the connection point 113, and the other end (the lower end in Figure 7) is connected to the radio frequency circuit 13. The radio frequency circuit 13 is connected to the floor 12, and the radio frequency circuit 13 is connected to the feed body 114, via a coaxial cable 14. The coaxial cable 14 includes an inner conductor 141 and an outer conductor 142 covering the outer periphery of the inner conductor 141. The ground port of the radio frequency circuit 13 is connected to the outer conductor 142, and the radio frequency port of the radio frequency circuit 13 is connected to the inner conductor 141. In addition, the outer conductor 142 is also connected to the floor 12, and the inner conductor 141 is also connected to the feed body 114. Therefore, both the first radiator 111 and the second radiator 112 can couple to the floor 12. The radio frequency signal generated by the radio frequency circuit 13 can be transmitted to the ground 12 and the radiating structure 11 through the coaxial cable 14, so that the capacitive structure formed by the ground 12 and the first radiator 111, as well as the capacitive structure formed by the ground 12 and the second radiator 112, radiate electromagnetic waves outward.

[0091] The example provided in Figure 7 illustrates an example where the radio frequency circuit 13 is connected to the floor 12 and the radiating structure 11 via a coaxial cable 14. In other examples, the coaxial cable 14 may be replaced with a radio frequency transmission line such as a microstrip line or a coaxial stripline, which will not be described in detail here.

[0092] As shown in Figure 6, a transverse current exists in the first radiator 111 (indicated by the dashed arrow in Figure 6), and a transverse current also exists in the second radiator 112 (indicated by the dashed arrow in Figure 6). The feed body 114 and the ground body 115 are both connected between the first radiator 111 and the second radiator 112. Therefore, the flow directions of the transverse currents in the first radiator 111 and the second radiator 112 are opposite. That is, the transverse currents in the two radiators can partially or completely cancel each other out, thereby reducing the radiation intensity of the antenna 10 in the normal direction. This helps to improve the radiation gain of the antenna 10 in the plane parallel to the ground 12, giving the antenna 10 better omnidirectionality in the plane parallel to the ground 12, enabling it to achieve a large-area wireless signal coverage. The dashed lines in Figure 7 show the approximate radiation pattern of the wireless signal from the antenna 10. For example, in a plane perpendicular to the normal, the wireless signal from the antenna 10 can achieve nearly 360° effective coverage.

[0093] Since the connection 113 is located between the first radiator 111 and the second radiator 112, in the embodiments of this application, the connection 113 can have a variety of different forms.

[0094] In this embodiment, the connection 113 can be a point, a line (e.g., a straight line, a curve, or other possible forms of line), a sheet-like region or surface with a certain shape and area (the thickness of the sheet-like region or surface is less than a threshold, for example, the threshold can be 1 mm, then the thickness of the sheet-like region or surface can be any thickness within 1 mm, further, it can be any value from 0.3 mm to 0.7 mm, or a larger or smaller value, this application is not limited, in which case the connection 113 can also be called a surface structure, sheet structure, or planar structure), or it can be other three-dimensional structures, without limitation. For example, the surface or cross-section of the sheet-like region can be a regular or irregular surface, such as a rectangle, square, circle, ellipse, rhombus, or other regular or irregular shape, without limitation. The connection 113 mentioned above can be an actual point, line, surface or three-dimensional structure that is different from the first radiator 111 and the second radiator 112, or it can be a point, line, surface or three-dimensional structure that is artificially divided or virtualized for the purpose of describing the connection relationship between the first radiator 111 and the second radiator 112. This application does not impose any restrictions.

[0095] When the connection point is a structure with a certain shape and area, it can also be called a connecting body, a connecting structure, or other names without limitation. For example, in the example provided in Figure 5, the connection point 113 is shown as a rectangular sheet or planar structure. In this case, the connection point can also be called a connecting body 1130, a connecting surface 1130, a connecting piece 1130, or other terms without limitation. For example, as shown in Figures 8 and 9, the first radiator 111 and the second radiator 112 are connected by a line, i.e., the connection point is a line. This line can be an actual line or an artificially defined or virtual line to describe the connection relationship between the first radiator 111 and the second radiator 112, without limitation. If the first radiator 111 and the second radiator 112 are projected onto a plane, the connection point 113 can be a point. This point can be an actual point or an artificially defined or virtual point to describe the connection relationship between the first radiator 111 and the second radiator 112, without limitation. The embodiments of this application do not limit the form in which the connection 113 exists.

[0096] To facilitate understanding or description of the technical solution of this application, the following examples will use a planar or sheet-like structure as an example. When the connection 113 has a distinct shape and area, it can provide sufficient area to connect with the feed body 114 and the ground body 115. This improves the ease of fabrication of the radiator structure 11.

[0097] In this embodiment, the entire area of ​​the connection 113 can be considered to belong to either the first radiator 111 or the second radiator 112. Alternatively, a portion of the connection 113 can be considered to belong to the first radiator 111, and another portion can be considered to belong to the second radiator 112. Or, at least a portion of the connection 113 can be considered to be independent of the first radiator 111 and the second radiator 112.

[0098] Taking Figure 5 as an example, the connection 113 can be the connector 1130 shown in Figure 5, or any point or any dividing line of the connector 1130 shown in Figure 5. Taking the connector 1130 as a line as an example, the half of the connection 113 located on one side of the line can be regarded as part of the first radiator 111, and the other half of the line can be regarded as part of the second radiator 112.

[0099] In one example provided in this application, as shown in FIG5, the connection 113 includes a connector 1130. In the example provided in FIG5, the entire area of ​​the connection 113 is the connector 1130, and the first end of the power supply 114 and the first end of the grounding body 115 are both connected to the connector 1130. In this case, the connector 1130 can be considered as the connection 113.

[0100] It is understood that in other examples, the connector 1130 may also be part of the connection 113. When the connector 1130 is part of the connection 113, the first end of the feed body 114 may be connected to the connector 1130, or the first end of the feed body 114 may also be connected to other areas of the connection 113; the first end of the ground body 115 may be connected to the connector 1130, or the first end of the ground body 115 may also be connected to other areas of the connection 113. In this case, when other parts of the connection 113 other than the connector 1130 are connected to the first radiator 111 and / or the second radiator 112, these other parts may be considered as structures independent of the first radiator 111 and / or the second radiator 112, or these other parts may be considered as part of the first radiator 111 and / or the second radiator 112 in close proximity, without limitation. For example, if the other part includes a portion connected to the first radiator 111 or the second radiator 112, then that portion can be considered as a structure independent of the first radiator 111 or the second radiator 112, or as a part of the first radiator 111 or the second radiator 112. Alternatively, if the other part includes a first portion and a second portion, with the first portion connected to the first radiator 111 and the second portion connected to the second radiator 112, then the first portion can be considered as a structure independent of the first radiator 111 or as a part of the first radiator 111, and the second portion can be considered as a structure independent of the second radiator 112 or as a part of the second radiator 112.

[0101] The relative positions between the first radiator 111 and the second radiator 112 can be varied.

[0102] In one example provided in this application, as shown in Figures 5, 6, 8, 9, 14, 15, 16A, 16B, and 17, the first radiator 111 and the second radiator 112 are both located in the same plane. This facilitates the mutual attenuation of the transverse current in the first radiator 111 and the transverse current in the second radiator 112.

[0103] In this application, when two or more structures are located in the same plane, it means that they are roughly or approximately in the same plane, and are not limited to the same plane in a strict sense. For example, there may be an angle between the plane where the first radiator 111 is located and the plane where the second radiator 112 is located that is less than or equal to a specific threshold (e.g., 1°, 2°, 5° or other possible values, which are not limited).

[0104] Figure 5 shows an example where the first radiator 111 and the second radiator 112 are both located in the same plane. When the radiators shown in Figure 5 are installed in an antenna, as shown in Figure 6, the plane containing the first radiator 111 and the second radiator 112 can be parallel or approximately parallel to the floor. Figures 8 and 9 show another example where the first radiator 111 and the second radiator 112 are both located in the same plane. Figure 14 shows yet another example where the first radiator 111 and the second radiator 112 are both located in the same plane. When the radiators shown in Figure 14 are installed in an antenna, as shown in Figure 15, the plane containing the first radiator 111 and the second radiator 112 can be parallel or approximately parallel to the floor. Figures 16A and 16B show yet another example where the first radiator 111 and the second radiator 112 are both located in the same plane. When the radiator shown in Figure 16A is installed in an antenna, as shown in Figure 17, the plane containing the first radiator 111 and the second radiator 112 can be perpendicular or approximately perpendicular to the floor.

[0105] Optionally, the connection 113 may be located in the same plane as the first radiator 111 (or the second radiator 112). As shown in Figure 5 or Figure 6, or Figures 8 and 9, or Figures 16A, 16B and 17, this helps to improve the ease of manufacturing the radiating structure 11.

[0106] Alternatively, the surface of the connection 113 may form an angle with the plane containing the first radiator 111 (or the second radiator 112). This angle may be referred to as the first angle. For example, if the connection 113 is a planar structure, the plane containing the connection 113 may form an angle with the plane containing the first radiator 111 (or the second radiator 112). As another example, if the connection 113 is a non-planar structure (e.g., a curved surface or other non-planar structure), the main surface or one of the surfaces of the connection 113 may form an angle with the first radiator 111 (or the second radiator 112), as shown in Figure 14 or Figure 15. This helps to save space or reduce the size of the radiating structure 11.

[0107] For example, in the example provided in Figure 14, the first included angle is equal to or approximately equal to 90°, meaning the main surface of the connection 113 is a plane, and this main surface is perpendicular to the first plane. In other examples, the included angle between the surface where the connection 113 is located and the first plane can also be any other angle such as 89° or 70°. As shown in Figure 15, when the radiating structure 11 shown in Figure 14 is applied in the antenna 10, the first plane containing the first radiator 111 and the second radiator 112 is parallel to the floor 12, and the plane containing the connection 113 is perpendicular to the floor 12. In the examples provided in Figures 14 and 15, the first radiator 111 and the connection 113 are connected by a curved structure 1111, and the second radiator 112 and the connection 113 are connected by a curved structure 1121. In one implementation, structure 1111 can be considered as part of the first radiator 111, or as part of the connector 113, or as an independent structure. Correspondingly, structure 1121 can be considered as part of the second radiator 112, or as part of the connector 113, or as an independent structure. When structures 1111 and / or 1121 are considered part of the connector 113, the connector 113 is a non-planar structure, but its main structure is a planar structure, and this planar structure is perpendicular to the first plane.

[0108] With the above structure, the first radiator 111 and the second radiator 112 are located in the same plane, and the connection 113 connects the first radiator 111 and the second radiator 112. This structure facilitates the integrated fabrication of the first radiator 111, the second radiator 112, and the connection 113. With this structure, the feed current can flow from the connection 113 to the first radiator 111 and the second radiator 112 respectively, so that the direction of the transverse current in the first radiator 111 is opposite to the direction of the transverse current in the second radiator 112. Therefore, it helps to achieve mutual attenuation of the transverse currents in the two radiators.

[0109] In another example provided in this application, the plane containing the first radiator 111 and the plane containing the second radiator 112 can be parallel to each other, as shown in Figures 10, 11A, 11B, 11C, and 14A. This is beneficial for achieving mutual attenuation of the transverse current in the first radiator 111 and the transverse current in the second radiator 112.

[0110] When the plane containing the first radiator 111 and the plane containing the second radiator 112 are parallel to each other, and the radiators are used in the antenna 10, both the first radiator 111 and the second radiator 112 are parallel to the ground plane 12, and the distance between the first radiator 111 and the ground plane 12 is different from the distance between the second radiator 112 and the ground plane 12. The difference between the distance between the first radiator 111 and the ground plane 12 and the distance between the second radiator 112 and the ground plane 12 can be designed according to the needs of the product application. For example, the difference can be any value such as 1 cm, 3 cm, 4 cm, etc., and this application is not limited to this. Taking the radiating structure 11 shown in Figure 10 as an example applied to the antenna, as shown in Figure 11A.

[0111] Optionally, the plane containing the connection 113 may form an angle with the plane containing the first radiator 111 (or the second radiator 112), as shown in the examples in Figures 11B and 14A. This angle can be any value greater than 0° and less than 90°, without limitation. For example, in Figure 11B, the angle can be any value greater than 0° and less than 90°, while in Figure 14A, the angle is 90°. The plane containing the connection 113 can be designed according to actual production applications and is not limited. The description of the connection in Figure 14A can be referenced from the description in Figure 14, and will not be repeated here.

[0112] For example, the connection 113 is a planar structure, and the plane where the connection 113 is located may have an angle with the plane where the first radiator 111 (or the second radiator 112) is located, as shown in Figure 11B.

[0113] For example, the connection 113 is a non-planar structure (e.g., a curved structure or other non-planar structure), and there is an angle between the main surface or one of the surfaces of the connection 113 and the first radiator 111 (or the second radiator 112), as shown in Figure 14A. This helps to reduce the size of the radiating structure 11, thereby reducing the size of the antenna.

[0114] Optionally, the surface of the connector 113 can be parallel to the plane containing the first radiator 111 and the plane containing the second radiator 112, as shown in Figure 11C. For example, if the connector 113 is a planar structure, the plane containing the connector 113 can be parallel to both the plane containing the first radiator 111 and the plane containing the second radiator 112. Since the connector 113 has a certain thickness, and there is a certain height difference between the first surface and the second surface of the connector 113, either the first radiator 111 or the second radiator 112 can be connected to the surface closest to the connector 113, and the other can be connected to the surface closest to the connector 113. As another example, if the connector 113 is a non-planar structure (e.g., a wavy curved surface or a stepped or other non-planar structure), the main surface or one of the surfaces of the connector 113 can be parallel to the plane containing the first radiator 111 and the plane containing the second radiator 112.

[0115] Optionally, the surface where the connection 113 is located can be parallel to the plane where the first radiator 111 is located or the plane where the second radiator 112 is located, and the connection 113 is coplanar with the plane where the first radiator 111 is located or the plane where the second radiator 112 is located. As shown in Figure 10, since the connection 113 has a certain thickness, either the first radiator 111 or the second radiator 112 can be connected to the first surface near the connection 113, and the other can be coplanar with the connection 113.

[0116] In another example provided in this application, the plane containing the first radiator 111 and the plane containing the second radiator 112 can also form an angle. Taking Figures 12, 13, and 14B as examples, when the radiating structure shown in Figures 12 and 14B is applied to the antenna 10, the plane containing the first radiator 111 has a second angle with the ground, and the plane containing the second radiator 112 has a third angle with the ground. The second and third angles can be the same or different; this application does not limit this. The values ​​of both the second and third angles are greater than 0° and less than 90°, and any angle within the above range can be selected in specific applications; this application does not limit this.

[0117] In one possible implementation, the connection 113 is a planar structure, and the plane containing the connection 113 can form angles with the plane containing the first radiator 111 and the plane containing the second radiator 112. The angle between the plane containing the first radiator 111 and the plane containing the connection 113 can be the same as or different from the angle between the plane containing the second radiator 112 and the plane containing the connection 113.

[0118] Wherein, when the plane containing the connection 113 can form an angle with the plane containing the first radiator 111 and / or the plane containing the second radiator 112, the connection 113 can have various angles with the floor when the radiator is applied in the antenna 10. As shown in Figure 12, the plane containing the connection 113 can form an angle with the plane containing the first radiator 111 and the plane containing the second radiator 112. When the radiating structure shown in Figure 12 is applied in the antenna 10, as shown in Figure 13, the plane containing the connection can be parallel to the floor. As shown in Figure 14B, the plane containing the connection 113 can form an angle with the plane containing the first radiator 111 and the plane containing the second radiator 112. When the radiating structure shown in Figure 14B is applied in the antenna 10, the plane containing the connection can have an angle with the floor, such as 90° or other possible angles. Optionally, the connection, the first radiator 111, and the second radiator 112 can be understood as forming an approximate umbrella shape.

[0119] In one possible implementation, the connection 113 is a planar structure. The plane where the connection 113 is located can form an angle with the plane where the first radiator 111 is located or the plane where the second radiator 112 is located. The connection 113 is a planar structure and can be located in the same plane as the first radiator 111 or the second radiator 112. That is, the connection, the first radiator and the second radiator form an approximate V-shape.

[0120] One possible implementation is that the connection 113 is a non-planar structure (e.g., a wavy curved surface structure or a stepped or other non-planar structure). The main surface of the connection 113 or one of its surfaces has an angle with the first radiator 111 and the second radiator 112 respectively. This can be referred to the description when the connection 113 is in the plane, and will not be repeated here.

[0121] This structure helps to better cancel or partially cancel lateral current. The above radiator example is applied as a whole in the antenna. The angle between the first radiator 111 and the ground plane 12, and the angle between the second radiator 112 and the ground plane 12, can be the same or different. Alternatively, in some examples, the first radiator 111 can be parallel to the ground plane 12, and the second radiator 112 can be at an angle to the ground plane 12. Or, the second radiator 112 can be parallel to the ground plane 12, and the first radiator 111 can be parallel to the ground plane 12. These structures reduce the difficulty of the manufacturing process.

[0122] In the embodiments provided in this application, the planes containing two or more structures are at an angle, including the planes containing these structures intersecting or the planes containing these structures intersecting after being theoretically extended.

[0123] In one example, the locations of the power supply 114 and the grounding body 115 can also have a variety of options.

[0124] In one example provided in this application, as shown in Figures 14, 14A, 14B, 16A, 16B, 20B, and 20C, the first end of the feed element 114 and the first end of the ground element 115 are connected to the same side of the connection 113. The second end of the feed element 114 and the second end of the ground element 115 extend in the same direction, but their directions of extension are away from the connection 113. This facilitates the connection of the radiating structure 11 to the ground plane 12. Taking Figure 16A as an example, when the radiating structure 11 in Figure 16A is applied to the antenna 10, as shown in Figure 17, since the second end of the feed element 114 and the second end of the ground element 115 extend in the same direction, it is convenient to connect the ground element 115 to the ground plane 12. At the same time, it is also convenient to connect the second end of the feed element 114 to the radio frequency circuit after passing through the ground plane 12. Figure 20B is a simplified topology diagram of Figures 14 to 14B, in which the first end of the feed body 114 and the first end of the ground body 115 are both connected to one side of the connection 113. Figure 20C is a simplified topology diagram of Figures 16A and 16B, in which the example of the first radiator 111 and the second radiator 112 being connected to the left and right sides of the connection 113 respectively is described, and the first end of the feed body 114 and the first end of the ground body 115 are both connected to the same side of the connection 113 (shown in the figure as being connected to the lower side of the connection 113).

[0125] In another example provided in this application, as shown in Figures 5, 10, 11B, 11C, 12, 20, and 20A, the first end of the feed body 114 and the first end of the ground body 115 are respectively connected to both sides of the connection 113. The second ends of the feed body 114 and the second ends of the ground body 115 extend in the same direction, but the direction of extension is away from the connection 113. Figure 20A is a simplified topology diagram of Figures 5, 10, 11B, 11C, 12, and 20, wherein, taking the example of the first radiating structure 111 and the second radiating structure 112 being connected to the left and right sides of the connection 113 respectively, the first end of the feed body 114 and the first end of the ground body 115 are respectively connected to the upper and lower sides of the connection 113. Therefore, it is also convenient to realize the connection between the ground body 115 and the ground plane 12, and to facilitate the connection of the second end of the feed body 114 to the radio frequency circuit after passing through the ground plane 12.

[0126] Regardless of the connection method by which the power supply 114 and the grounding body 115 are connected to the connection point 113, the second end of the power supply 114 and the second end of the grounding body 115 extend in the same direction.

[0127] Taking Figures 5 to 13 and Figures 16A to 17 as examples, the feed body 114 and the ground body 115 can be arranged in parallel. Furthermore, the feed body 114 and the ground body 115 can have a partially parallel design, as shown in Figure 14 or Figure 15. In the example provided in Figure 14, the ground body 115 has a bent structure, roughly L-shaped. The bent structure increases the length of the ground body 115, facilitating the adjustment of parameters such as bandwidth VSWR matching and impedance matching of the antenna 10. It also improves the ease of connection between the second end of the ground body 115 and the second end of the feed body 114 and the ground plane 12.

[0128] In other examples, the feed element 114 may also be a bent structure. Alternatively, both the feed element 114 and the grounding element 115 may be bent structures. That is, the extension directions of the second end of the feed element 114 and the second end of the grounding element 115 may be different. Alternatively, the extension direction of the second end of the feed element 114 may be a fixed direction or multiple different directions. Correspondingly, the extension direction of the second end of the grounding element 115 may be a fixed direction or multiple different directions.

[0129] Regardless of the method by which the feed element 114 and the ground element 115 are connected to the connection point 113, one possible implementation is that the first end of the feed element 114 and the first end of the ground element 115 are symmetrical about a first point in the connection point 113. This point can be an actual point or a point artificially drawn to describe the symmetry; there is no limitation. This symmetrical arrangement ensures that the paths of the radio frequency signals in the feed element 114 and the ground element 115 as they flow through the connection point 113 are symmetrical (or opposite). Therefore, the currents in the connection point 113 can cancel each other out as much as possible, reducing the degree to which the connection point 113 generates normal radiation and degrades the radiation performance of the antenna 10.

[0130] The first point could be, for example, the geometric center, center of gravity, or other possible point at connection 113. This first point can be a physically existing point, a theoretical geometric point, or a point of other types; this application is not limited to any of these. The symmetry in this application can include at least one of central symmetry, rotational symmetry, mirror symmetry, and axial symmetry. It should be understood that symmetry in this application does not only include strict symmetry. When features such as patterns and positions exhibit a symmetrical trend, or when the portion of the aforementioned features exceeding a certain threshold satisfies the symmetry condition, it falls within the scope of this application. Taking Figures 16A and 16B as examples, the first point could be point 1131 in the figure.

[0131] The aforementioned symmetry includes the symmetry between the connection position of the first end of the feeder 114 at the connection point 113 and the connection position of the first end of the grounding electrode 115 at the connection point 113. It can also be understood as the symmetry between the midpoint of the connection position of the first end of the feeder 114 at the connection point 113 and the midpoint of the connection position of the first end of the grounding electrode 115 at the connection point 113. For example, as shown in Figure 16A, the shape of the grounding electrode 115 is different from that of the feeder 114. The cross-sectional area of ​​the first end of the grounding electrode 115 is larger than that of the first end of the feeder 114. The center point where the first end of the feeder 114 connects to the connection point 113 and the center point where the first end of the grounding electrode 115 connects to the connection point 113 are symmetrical about the first point 1131.

[0132] Furthermore, the feed body 114 and the ground body 115 can also be symmetrical about the first point in the connection 113. Then, the feed body 114 and the ground body 115 have the same shape, and the connection position of the first end of the feed body 114 at the connection 113 is symmetrical to the connection position of the first end of the ground body 115 at the connection 113. For example, as shown in Figure 16B, the feed body 114 and the ground body 115 have the same shape and area, and are symmetrical about the first point 1131 in the connection 113. Therefore, the first ends of the feed body 114 and the first ends of the ground body 115 are symmetrical about the first point in the connection 113.

[0133] To further enhance the degree of mutual cancellation of transverse currents in the first radiator 111 and the second radiator 112, a symmetrical structural design can also be adopted between the first radiator 111 and the second radiator 112.

[0134] In one example provided in this application, the first radiator 111 and the second radiator 112 can further be symmetrical about the connection 113. With this structure, taking the radiator shown in FIG5 as an example applied to the antenna 10, as shown in FIG6, there is a transverse current in the first radiator 111 (as shown by the dashed arrow in FIG6), and there is also a transverse current in the second radiator 112 (as shown by the dashed arrow in FIG6). The feed body 114 and the ground body 115 are both connected between the first radiator 111 and the second radiator 112. When the first radiator 111 and the second radiator 112 are symmetrical about the connection point 113, the flow direction of the transverse current in the first radiator 111 and the second radiator 112 is further opposite. The transverse current in the two radiators can be partially or completely canceled out, thereby further reducing the radiation intensity of the antenna 10 in the normal direction. This helps to improve the radiation gain of the antenna 10 in the plane parallel to the ground 12, so that the antenna 10 has good omnidirectionality in the plane parallel to the ground 12 and can achieve a large range of wireless signal coverage.

[0135] One possible implementation of symmetry between the first radiator 111 and the second radiator 112 about the connection 113 includes: the first radiator 111 and the second radiator 112 are symmetrical about a second point in the connection 113. The projection of either the first radiator 111 or the second radiator 112 in a certain direction can be of any shape, such as a circle, rectangle, rhombus, triangle, or other regular or irregular shapes. Furthermore, the shape and size of the first radiator 111 and the second radiator 112 can be the same or different. The symmetry between the first radiator 111 and the second radiator 112 about the second point in the connection 113 can include: when the first radiator 111 and the second radiator 112 are identical, the first radiator 111 and the second radiator 112 are symmetrical about the second point; or, when the shapes of the first radiator 111 and the second radiator 112 are not identical, the center point of the first radiator 111 and the center point of the second radiator 112 are symmetrical about the second point.

[0136] Any method that ensures at least a portion of the transverse currents of the two radiators cancel each other out is within the scope of protection of this application. Furthermore, this description applies to any implementation provided in this application, and will not be elaborated further.

[0137] The second point can be the geometric center, center point, centroid, or other possible point of the connection 113. This second point can be a physically existing point, a theoretical geometric point, or other types of points; this application is not limited to any particular point. Furthermore, as mentioned in the above example, the first end of the feed body 114 and the first end of the ground body 115 are symmetrical about the first point in the connection 113. In some cases, the first point and the second point can be the same point in the connection 113 or different points; this is not limited. Figure 20 is a projected schematic diagram of the radiating structure 11 shown in Figure 5. As shown in Figure 20, the first radiator 111 and the second radiator 112 are symmetrical about the second point 1132 in the connection 113.

[0138] The aforementioned symmetry about the second point can be rotational symmetry about the second point. This means the first radiator 111 and the second radiator 112 are rotationally symmetric about the second point in space, or the projections of the first radiator 111 and the second radiator 112 onto a certain plane are rotationally symmetric about the second point.

[0139] One possible implementation, in which the first radiator 111 and the second radiator 112 are symmetrical about the connection 113, includes: the first radiator 111 and the second radiator 112 being mirror-symmetrical about a first line in the connection 113.

[0140] Specifically, the first line can be a line passing through the connection 113. This line can be an actual existing line or an artificially drawn line to describe symmetry; there are no restrictions. The position where the first line passes through the connection 113 can be arbitrary. Alternatively, the first line can be at least one of multiple lines passing through the second point. For example, the first line can be the central axis of the connection 113. When the connection itself has symmetrical characteristics, the central axis can refer to the center line of symmetry of the connection 113 itself, that is, the connection 113 is symmetrical about the central axis.

[0141] In some cases, the central axis may or may not pass through the second point. For example, the central axis may pass through any point near the second point, or the central axis may pass through any point in the connection 113.

[0142] The radiation structure provided in this application is applicable to the radiation pattern of antenna 10, as shown in Figures 18 and 19, where darker colors indicate higher signal strength. Figure 18 shows the three-dimensional radiation pattern of the radiated signal energy of antenna 10, and Figure 19 shows the radiation pattern of the radiated signal energy of antenna 10 in the XY plane. As can be seen from Figures 18 and 19, antenna 10 can achieve 360° signal coverage in the XY plane, exhibiting good omnidirectionality. Furthermore, the radiation intensity is weaker in the central region and stronger at the edges of the radiation pattern. Therefore, the radiation intensity of antenna 10 is weaker in the normal direction (e.g., the Z-axis direction), resulting in better radiation safety. Moreover, a large range of signal coverage can be achieved in the XY plane. For example, when the radiation structure 11 shown in Figure 5 is applied to the antenna of the base station shown in Figure 1, the radiation intensity of antenna 10 will be lower than a certain threshold within the 0° to ±θ angle range shown in Figure 1. Specifically, θ can be any value from 0° to 45°. For example, θ can be 30°, 45°, etc. Alternatively, θ can be any other value, which will not be elaborated here. Furthermore, the radiated energy is increased within the angular range of ±θ to ±θ1.

[0143] The symmetry in this application can include at least one of central symmetry, rotational symmetry, mirror symmetry, and axial symmetry. It should be understood that symmetry in this application does not only include strict symmetry; when features such as patterns and positions exhibit a symmetrical trend, or when the portion of the aforementioned features exceeding a certain threshold satisfies the condition of symmetry, it falls within the scope of this application. In the example provided in this application, the radiating structure 11 can be a single-piece structure. The radiating structure 11 can be integrally formed during production. Alternatively, it can be described that the connection 113, feed body 114, ground body 115, first radiator 111, and second radiator 112 included in the radiating structure 11 are an integral structure. This method has the advantages of simple structure and ease of manufacturing, effectively reducing the manufacturing cost of the radiating structure 11 and improving manufacturing efficiency, and reducing solder joints, thus improving production efficiency. The radiating structure 11 can be a metal sheet metal part, a copper layer in a printed circuit board (PCB), or a copper layer in a flexible printed circuit (FPC), without limitation. The radiating structure 11 can be integrally formed using processes such as stamping, cutting, and bending.

[0144] Alternatively, in some examples, parts of the radial structure 11 are integrally formed. Other parts of the radial structure 11 can also be fabricated separately and then joined together using processes such as welding. In actual production, the choice of which structures can be integrally formed can be made according to requirements.

[0145] Furthermore, the one-piece molding process can also save on manufacturing costs to some extent. For example, taking the radial structure shown in Figure 16A as an example, as shown in Figure 21. The dashed outline in Figure 21 shows the approximate outline of the blank. When manufacturing the radial structure 11 shown in Figure 16A, the blank needs to be cut to remove the parts other than the radial structure 11. In the examples provided in Figures 16A and 21, the connection 113 is connected to the corner of the first radiator 111 and the connection 113 is connected to the corner of the second radiator 112. Therefore, no excess waste is generated on one side of the blank (the upper side in Figure 21), which helps to improve the efficiency of material use and thus reduce manufacturing costs.

[0146] Alternatively, taking the radial structure shown in Figure 14 as an example, as shown in Figure 22, the dashed outline in Figure 22 shows the approximate outline of the blank. The radial structure 11 shown in Figure 22 is the structure of the radial structure 11 shown in Figure 14 before bending. The connection 113 connects to the corner of the first radiator 111 and the corner of the second radiator 112. Therefore, no excess waste is generated on one side of the blank (the upper side in Figure 22), which helps improve material utilization efficiency and thus reduce manufacturing costs.

[0147] In this embodiment, the specific shapes of the first radiator 111, the second radiator 112, the feeder 114, and the grounder 115 may differ from the figures shown above. For ease of understanding, the above example uses a sheet-like structure for illustration, where the first radiator 111, the second radiator 112, the feeder 114, and the grounder 115 are all sheet-like. That is, the thickness of each region is basically the same, and the thickness is less than a certain threshold. The thickness of any two structures can be the same or different.

[0148] In other examples, the first radiator 111 or the second radiator 112 may be a block-like or other structural shape. Here, a block shape can be considered as a structural shape with a thickness greater than a certain threshold.

[0149] Either the power supply body 114 or the grounding body 115 can be a block-shaped, column-shaped or other structural shape.

[0150] It should be understood that the different embodiments provided above are merely examples of this application, and other variations may exist. They should not be construed as limiting product implementation to only the aforementioned methods. Other solutions utilizing this transverse current cancellation approach are also within the scope of protection of this application.

[0151] As shown in Figure 23, when the radiating structure 11 is used in the antenna 10, the radiating structure 11 is located on one side of the ground plane 12. The first end of the grounding body 115 is connected to the connection point 113, and the second end is connected to the ground plane 12. The first end of the feed body 114 is connected to the connection point 113, and the second end passes through the ground plane 12 and is connected to the radio frequency circuit 013. It should be noted that the radio frequency circuit 013 includes a feed port and a ground port. Specifically, the feed port of the radio frequency circuit 013 is connected to the second end of the feed body 114 via transmission line 014. The ground port of the radio frequency circuit 013 is connected to the ground plane 12 via transmission line 015.

[0152] In addition to any of the above-mentioned radiating structures 11, antenna 10 may also include a feeding network.

[0153] For example, in one example provided in this application, as shown in FIG24, the antenna also includes a feed network.

[0154] Specifically, this antenna is used in communication equipment, which also includes radio frequency (RF) circuits. The RF circuits are connected to the feed body and ground body via a feed network, meaning the feed network connects the RF circuits, the radiating structure, and the ground plane. The antenna may include one or more radiating structures (two are shown in Figure 24), the ground port of the feed network is connected to the ground plane, and the feed output port of the feed network can be connected to the feed body of the radiating structure.

[0155] The main function of the feed network is to feed the signals from the radio frequency circuit to the radiating structure according to a certain amplitude and phase. The feed network may include at least one of the following devices: phase shifter, combiner, drive or calibration network, or filter. This application does not limit the components, type, or functions that the feed network can achieve.

[0156] By configuring the feed network, parameters such as phase can be effectively adjusted to enable the antenna to have beam scanning capabilities, which can effectively improve the antenna's signal coverage.

[0157] It is understandable that in some examples, the antenna may not include a feed network, and the radio frequency circuitry may be directly connected to the ground plane and feed body in the antenna, which will not be elaborated here.

[0158] Furthermore, the example provided in Figure 24 is an illustrative example of a communication device including radio frequency (RF) circuitry. In other examples, the RF circuitry may also be located at a remote end, and the RF circuitry and the antenna may be connected to the ground and feeder via a long coaxial cable or similar cable. That is, the communication device may or may not include RF circuitry, which will not be elaborated further here.

[0159] In the various embodiments of this application, unless otherwise specified or in case of logical conflict, the terminology and / or descriptions between different embodiments are consistent and can be referenced by each other. Technical features in different embodiments can be combined to form new embodiments based on their inherent logical relationships.

[0160] In this application, the connection can be direct or indirect. For example, when A and B are directly connected, the connection between A and B can be achieved without relying on other structures or materials. When A and B are indirectly connected, the connection between A and B can be achieved through materials such as adhesives or solders; or, A and B can also be connected through other structural components C, or A and B can be coupled together, etc. "Multiple" refers to two or more. "And / or" describes the relationship between the related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone, where A and B can be singular or plural.

[0161] It is understood that the various numerical designations used in the embodiments of this application are merely for descriptive convenience and are not intended to limit the scope of the embodiments of this application.
