Technical Field

[0071] Figure 1 A structural example diagram of an antenna system applied to base station 1 is shown. (Reference) Figure 1 Base station 1 includes antenna system 01 (also referred to as antenna 01), radio frequency unit 05, and baseband unit (BBU) 06. Optionally, radio frequency unit 05 and antenna system 01 can be integrated into one unit. Figure 1(Not shown in the image). For example, the integrated unit can be an AAU. The integrated radio frequency unit can also be called the radio frequency system of the AAU, radio frequency module, etc., without limitation. Optionally, base station 1 may also include one or more of the following: antenna adjustment bracket 02, mounting bracket 03, cable 04 and cable 10, grounding device 07, and connector seal 08. For example, antenna system 01 can be mounted on mounting bracket 03 via antenna adjustment bracket 02, wherein antenna adjustment bracket 02 is used to adjust the downtilt angle of antenna system 01 to facilitate signal reception or transmission. As another example, base station 1 may not include antenna adjustment bracket 02, as long as it includes a bracket capable of mounting antenna system 01 on mounting bracket 03, which may not have downtilt angle adjustment function. As yet another example, antenna system 01 can also be directly mounted on mounting bracket 03. Mounting bracket 03 can be a pole or tower, etc., without limitation.

[0072] Antenna system 01 may include radome 12. Various components are typically housed within antenna system 01, covered or enclosed by radome 12, such as one or more of the following: antenna array, reflector (or base plate, structural plate, etc., not shown in the figure), feed network (or power distribution network, not shown in the figure), remote control unit (RCU) (not shown in the figure), and transmission structure (not shown in the figure). Radome 12 possesses good electromagnetic wave penetration characteristics in terms of electrical performance and can withstand the effects of harsh external environments in terms of mechanical performance, thus protecting the components inside radome 12 from external environmental influences. Antenna system includes one or more antenna arrays. An antenna array includes one or more radiating elements. The radiating element of antenna system may also be called an antenna vibrator (e.g., shown as 11 in the figure). An antenna vibrator can be simply referred to as a vibrator and has the function of radiating electromagnetic waves. The feed network of antenna system (or power distribution network, feed circuit, or power distribution circuit, etc.) implements the feed function, that is, the function of transmitting electrical signals. In the antenna field, the feed function can also be called the power supply function, or in other words, providing energy. The function of the feed network is to feed signals to the radiating elements of the antenna with a certain amplitude and phase, or to feed signals received from the radiating elements to the signal processing unit of the base station with a certain amplitude and phase. For example, the signal processing unit can be an RF unit or a BBU. Optionally, the feed network may include transmission lines. These transmission lines can be coaxial cables, microstrip lines (or striplines), or other forms of transmission lines, without limitation. Optionally, the feed network may also include one or more of the following devices: phase shifters, power dividers, combiners, filters, bridges, and German Institute for Standardization (DIN) connectors, etc.

[0075] The connector seal 08 can be located at the connection between the antenna radome of the antenna system 01 and the cable 10, and / or, the connector seal 08 can be located at the connection between the grounding device 07 and the cable 04, to provide insulation and sealing. For example, the connector seal 08 can be insulating sealing tape or polyvinyl chloride (PVC) insulating adhesive. The connector seal 08 can also have other structures and is not limited to the form of tape.

[0076] Figure 2 A structural example of a CPE, denoted as CPE2, is shown. CPE2 includes an antenna system 01, a communication module 09, and a housing 091. The antenna system 01 and the communication module 09 can be respectively disposed on the housing 091 or disposed inside the housing 091. For example, both can be disposed on the housing 091; both can be disposed inside the housing 091; or one can be disposed on the housing 091 and the other can be disposed inside the housing 091. The antenna system 01 can be connected to the communication module 09. Thus, the communication module 09 can send signals to the antenna system 01 to cause the antenna system 01 to radiate electromagnetic waves; or, the communication module 09 can also receive signals from the antenna system 01 and process those signals. In an exemplary embodiment, CPE2 includes an antenna system 01 and an antenna system 02 (not shown), where antenna system 01 is used to transmit and receive mobile cellular signals, and antenna system 02 is used to transmit and receive WLAN signals, etc. For example, communication module 09 receives a mobile cellular signal from antenna system 01, processes the signal, converts it into a WLAN signal, and then transmits it through antenna system 02. As another example, communication module 09 receives a WLAN signal from antenna system 02, processes the signal, converts it into a mobile cellular signal, and then transmits it through antenna system 01.

[0077] Figure 2 The structure of base station 1 and terminal equipment (CPE 2 is shown as an example) in this application is merely an example. The actual shape, size, location, and construction of the components in the base station and terminal equipment are not subject to change. Figure 1 and Figure 2The examples provided are not limited to these. Optionally, the base station and terminal equipment may include more or fewer components to achieve other functions. For example, base station 1 may also be equipped with more antennas to be able to transmit and receive more signals. Similarly, the terminal equipment may also include components such as circuit boards and / or heat sinks, which are not limited in this application.

[0078] As mentioned above, an antenna system includes one or more antenna arrays, and an antenna array includes one or more radiating elements. The radiating elements of an antenna include baluns and radiating arms, etc.

[0079] In one example, the balun and the radiating arm are electrically connected by welding. The balun is typically made of aluminum and requires surface plating to support the soldering between the balun and the radiating arm. The balun has a large surface area, and the extensive surface plating significantly increases the cost, energy consumption, and environmental impact of the antenna manufacturing process.

[0080] To address the aforementioned problems, this application provides a radiating element, as well as an antenna and communication device including the radiating element.

[0081] Figure 3 This application provides an antenna including a feed network ( Figure 3 (Not shown in the diagram) , reflector 2 and at least one radiating element 1 described below. Optionally, the antenna may also include radiating elements of other types or structures, without limitation.

[0082] In this antenna, at least one radiating element 1 is disposed on one side, one side, or the front of the reflector 2, thereby shielding electromagnetic waves from the other side, the other side, or the back of the reflector 2 and improving the anti-interference capability of the radiating element 1. Furthermore, the antenna can concentrate energy to transmit electromagnetic signals forward through the reflector 2, and can also improve the sensitivity of the received signals.

[0083] In addition, the power supply network is electrically connected to at least one of the above-mentioned radiating units 1, thereby enabling radio frequency signal transmission between the power supply network and the radiating units.

[0084] Specifically, the feed network can be electrically connected to each radiating element 1 in the antenna. One end of the feed network is connected to the radiating element 1, and the other end is electrically connected to the radio frequency (RF) unit, thereby enabling RF signal transmission between the radiating element 1 and the RF unit. The RF unit is used for transmitting and receiving RF signals.

[0085] For example, when the antenna is used as a transmitter of radio frequency signals, the radio frequency unit can transmit radio frequency signals to the radiating unit 1.

[0086] Alternatively, when the antenna is used as a receiver of radio frequency signals, the radio frequency unit can receive radio frequency signals from the radiating unit 1.

[0087] In one implementation, the antenna and radio frequency unit are integrated together, and the radio frequency unit, the feed network, and the radiating unit can be directly connected by cables.

[0088] In another implementation, the antenna and RF unit are not integrated together, and the feed network can be electrically connected to the RF signal port of the RF unit through wires or coupling structures.

[0089] It should be understood that the structures of any two radiation units 1 in at least one of the above-mentioned radiation units can be the same or different, without restriction.

[0090] For example, the at least one radiating element 1 can be entirely radiating elements with a single polarization direction, or it can be entirely radiating elements with a dual polarization direction.

[0091] For example, the at least one radiating element 1 may be partly a radiating element with a single polarization direction and partly a radiating element with a dual polarization direction.

[0092] In this context, the polarization directions of any two radiation units 1 in at least one radiation unit 1 can be the same or different.

[0093] For example, if at least one radiating element 1 includes two radiating elements with single polarization directions, the polarization directions of these two radiating elements can be the same or different. For example, one radiating element may be horizontally polarized, and the other may be vertically polarized. Another example is that one radiating element may be +45° polarized, and the other may be -45° polarized. This application does not limit the polarization direction of any radiating element 1 in the antenna.

[0094] For example, if at least one radiating element 1 includes two radiating elements with dual polarization directions, the polarization directions of these two radiating elements can be the same or different. For example, one radiating element may have horizontal and vertical polarization, while the other radiating element may have +45° and -45° polarization. This application does not limit the polarization direction of any radiating element 1 in the antenna.

[0095] It should be understood that at least one of the above-mentioned radiating elements 1 can be arranged in an array on one side of the reflector 2, as described below. Figures 4 to 13 The structure of the radiating unit 1 provided in this application will be described.

[0096] Figure 4 and Figure 5 The diagram illustrates the structure of a radiation element 1 (hereinafter referred to as radiation element 11) provided in this application in different observation directions. Radiation element 11 is a radiation element with a single polarization direction. Figure 4 and Figure 5 As shown, the radiating element 11 provided in this application can be disposed on the reflector 2 of the antenna. The radiating element 11 includes a first radiating arm 101, a second radiating arm 102, a balun 20, a first feed assembly 301, and a second feed assembly 302. Optionally, the balun 20, the first feed assembly 301, and the second feed assembly 302 can be collectively referred to as a balun. The first radiating arm 101 and the second radiating arm 102 can be collectively referred to as a first dipole.

[0097] The balun 20 is used for electrical connection to the reflector 2 of the antenna, and the second feed assembly 302 is electrically connected to the balun 20 by coupling. For example, the first end of the balun 20 is disposed on the reflector 2; the first radiating arm 101 and the second radiating arm 102 are disposed at the second end of the balun 20; the first end of the first feed assembly 301 is electrically connected to the first radiating arm 101, and the second end of the first feed assembly 301 is used for electrical connection to the feed network of the antenna; the second feed assembly 302 is electrically connected to the second radiating arm 102, and the second feed assembly 302 is electrically connected to the balun 20 by coupling.

[0098] In the embodiments of this application, the electrical connection between two electronic components can be a direct electrical connection or an indirect electrical connection, such as an electrical connection through coupling. This application does not limit the specific method of coupling. Coupling refers to the transfer of energy from one circuit part to another, such as capacitive coupling or inductive coupling.

[0099] The first power supply assembly 301 can be mounted or fixed to the balun 20. The second power supply assembly 302 can be mounted or fixed to the balun 20.

[0100] The first end of the balun 20 is disposed on the reflector 2, which can be understood as: the first end of the balun 20 is electrically connected to the reflector 2. This connection includes, but is not limited to: the first end of the balun 20 being directly connected to the reflector 2, or the first end of the balun 20 being coupled to the reflector 2. The connection of the first end of the balun 20 to the reflector 2 can also be understood as: the first end of the balun 20 being grounded. Optionally, the balun 20 can also be referred to as balun ground 20, or balun stratum 20, etc.

[0101] In one implementation, such as Figure 4 As shown, the direction from the first end to the second end of the balun 20 is the height direction of the balun 20, which is perpendicular to the reflector 2, that is, parallel to the z-axis.

[0102] Alternatively, in some other implementations, the height direction of the balun 20 is not perpendicular to the reflector 2. For example, the angle between the height direction of the balun 20 and the reflector 2 is an acute angle, that is, the angle between the height direction of the balun 20 and the z-axis is an acute angle. For ease of description, this application will use the example of the height direction of the balun 20 being perpendicular to the reflector 2.

[0103] The first radiating arm 101 and the second radiating arm 102 are disposed at the second end of the balun 20, which can be understood as the first radiating arm 101 and the second radiating arm 102 supporting the second end of the balun 20. For example, the first radiating arm 101 and the second radiating arm 102 are fixed to the second end of the balun 20 by a mounting assembly. Alternatively, the first radiating arm 101 and the second radiating arm 102 can also be attached to the second end of the balun 20 by means of insulating hot melt adhesive or the like.

[0104] Alternatively, the first radiating arm 101 and the second radiating arm 102 are disposed at the second end of the balun 20. This can also be understood as follows: the first radiating arm 101 and the second radiating arm 102 can be respectively installed together with the corresponding power supply components and indirectly disposed at the second end of the balun 20. For example, the first radiating arm 101 is connected to the first power supply component 301 at a position near the second end of the balun 20, and the first power supply component 301 is mounted on the balun 20; as another example, the second radiating arm 102 is connected to the second power supply component 302 at a position near the second end of the balun 20, and the second power supply component 302 is mounted on the balun 20.

[0105] The second power supply component 302 can be mounted on the balun 20 either by fixing it to the balun 20 with a mounting component or by attaching it to the balun 20 with a dielectric layer; there is no limitation on the method. For example, if the second power supply component 20 is electrically connected to the balun 20 via capacitive coupling, then a dielectric layer may be included between the second power supply component 20 and the balun. If the dielectric layer is an air layer, the second power supply component 20 can be fixed to the balun 20 with a mounting component; if the dielectric layer is another material with adhesive properties, the second power supply component 20 can be attached to the balun 20 with the dielectric layer. Specific installation methods can be found below. Figure 6 Introduction.

[0106] like Figure 4 or Figure 5 As shown, the first radiating arm 101 and the second radiating arm 102 are arranged parallel to the reflector, that is, the plane containing the first radiating arm 101 and the second radiating arm 102 is parallel to the xy plane and perpendicular to the z-axis. Alternatively, in some other implementations, the first radiating arm 101 and the second radiating arm 102 may not be arranged parallel to the reflector, and this application does not limit this.

[0107] In one possible implementation, the second end of the first feeding component 301 is electrically connected to the antenna's feeding network, which can be: the second end of the first feeding component 301 is electrically connected to the phase shifter of the feeding network.

[0108] The first power supply component 301 enables electrical connection between the power supply network and the radiation unit 11, that is, it enables electrical connection between the power supply network and the first radiation arm 104.

[0109] Furthermore, the second radiating arm 102 can be grounded via the second feeding component 302. Specifically, the second radiating arm 102 is electrically connected to the second feeding component 302, the second feeding component 302 is electrically connected to the balun 20 via coupling, and the balun 20 is electrically connected to the reflector 2, thereby achieving an electrical connection between the second radiating arm 102 and the reflector 2. Since the reflector 2 is grounded, the second radiating arm 102 is also grounded, i.e., the radiating element 11 is grounded. The second feeding component 302 can receive the radio frequency signal from the balun 20 via coupling and then transmit the radio frequency signal to the second radiating arm 102; alternatively, the second feeding component 302 can receive the radio frequency signal from the second radiating arm 102 and transmit it to the balun 20 via coupling.

[0110] The first dipole can both transmit and receive electromagnetic wave signals.

[0111] In one implementation, the first dipole can be used to transmit electromagnetic wave signals. In this case, the feed network can transmit a radio frequency signal to the first feed component 301, which can be transmitted to the first radiating arm 101 through the first feed component 301 and excite a radio frequency current on the second radiating arm 102, thereby generating an electromagnetic wave signal on the first dipole.

[0112] In another implementation, the first dipole can be used to receive electromagnetic wave signals. In this case, the first dipole receives the electromagnetic wave signals and transmits them to the feed network through the first feed component 301.

[0113] Through the aforementioned balun 20, the first feed assembly 301, and the second feed assembly 302, radio frequency signal transmission between the radiating arm and the feed network can be realized, and electromagnetic wave signals can be sent or received through the first dipole.

[0114] In one implementation, such as Figure 3 and Figure 4 As shown, the second power supply component 302 is electrically connected to the balun 20 via capacitive coupling. The following section will discuss this further. Figure 6 The method of capacitive coupling between the second feed component 302 and the balun 20 in the radiating unit 11 is described.

[0115] Figure 6 yes Figure 4 The left view, i.e. Figure 4 A view observed along the x-axis. For example... Figure 6 As shown, the first power supply component 301 and the second power supply component 302 are respectively disposed on both sides of the balun 20, and a first dielectric layer 401 is included between the balun 20 and the second power supply component 302.

[0116] Optionally, the first dielectric layer 401 can be an intangible dielectric layer or a tangible dielectric layer, without limitation. For example, the first dielectric layer 401 can be an air layer, or it can be a dielectric layer made of other materials, such as plastic, epoxy resin, and / or ceramics, etc., which are not limited in this application.

[0117] In some implementations, the second power supply component 302 can be fixed to the balun 20 by mounting components. For example, the second power supply component can be installed on the balun 20 by bolts or clips. This application does not limit the specific fixing method, as long as it can fix the second power supply component 10 to the balun 20.

[0118] For example, if the first dielectric layer 401 is a dielectric layer composed of tangible material, the second power supply component 302 can be directly fixed (e.g., glued) to the balun 20 through the first dielectric layer 401.

[0119] In some implementations, the second feeding component 302 can be a feeding sheet in the form of a microstrip line (also called a feeding wire). Optionally, the second feeding component 302 can be a serpentine line, a straight line, a gradient line, or other microstrip lines of arbitrary shape. This application does not limit the specific shape of the microstrip line.

[0120] Optionally, the second power supply component may also be referred to as a coupling power supply line, a coupling power supply plate, or other terms, without limitation.

[0121] The effect of capacitive coupling between the second power supply component 302 and the balun 20 is related to the area of ​​the second power supply component 302. This application does not limit the area and shape of the second power supply component 302, as long as capacitive coupling between the second power supply component 302 and the balun 20 can be achieved.

[0122] In some implementations, the equivalent electrical length of the second feed component 302 is one-quarter of the operating wavelength of the radiating element. In this embodiment, the equivalent electrical length refers to the phase delay generated when the electrical signal propagates in the feed component (e.g., the second feed component). For example, when the electrical signal passes through the second feed component, the phase delay of the electrical signal is one-quarter of the operating wavelength.

[0123] For example, if the second feed component 302 is a serpentine feed piece, the length of the feed piece can be approximately equal to the equivalent electrical length, and the length of the serpentine line can be one-quarter of the operating wavelength. For example, if the operating wavelength is 'a', the length of the feed piece can be approximately a / 4, where a is greater than 0. As another example, if the operating wavelength is a wavelength range, the length of the feed piece can be a value determined according to that wavelength range, for example, one-quarter of the center value of that wavelength range. For instance, if the operating wavelength range is from a to b, the length of the feed piece can be approximately [(a+b) / 2] / 4, where a and b are greater than 0, and b is greater than a.

[0124] The first power supply component 301 can be mounted or fixed to the balun 20. Similar to the fixing method of the second power supply component 302 to the balun 20, in some implementations, the first power supply component 301 can be fixed to the balun 20 via a dielectric layer 402. For example, a dielectric layer 402 may be included between the balun 20 and the first power supply component 301, and the first power supply component can be mounted to the balun 20 via bolts or clips. Optionally, the dielectric layer 402 can be an air layer or a dielectric layer made of other materials; this application does not limit this. In some implementations, the first power supply component 301 can also be fixed to the balun 20 via a mounting component. The first power supply component can be a power supply sheet.

[0125] Figure 7 yes Figure 4 Top view, such as Figure 7 As shown, for ease of description, this application considers the x-axis direction as horizontal and the y-axis direction as vertical. Figure 7 The radiation element 11 shown is a radiation element with a 45° oblique polarization direction.

[0126] This application does not limit the polarization direction of the radiating element; that is, the polarization direction of the radiating element 11 can be any direction. For example, Figure 8 This is a top view of another type of radiating element 1, which is also a single-polarization radiating element, with its polarization direction being horizontal. For example, Figure 9 This is a top view of another type of radiating unit 1, which is also a radiating unit with a single polarization direction, and its polarization direction is vertical.

[0127] in, Figure 8 and Figure 9 The specific structure of the radiating unit 1 shown can be referred to Figures 4 to 6 The structure of the radiation unit 11 shown.

[0128] The above Figures 4 to 9 The radiating element 1 shown is a single-polarization radiating element. It should be understood that radiating element 1 in the antenna can also be a dual-polarization radiating element. The following will discuss this further. Figures 10 to 12 Let me introduce it.

[0129] Figure 10 and Figure 11 This application provides a schematic diagram of the structure of another radiating element 1 (hereinafter referred to as radiating element 12) in different observation directions. This radiating element 12 is a radiating element with a dual-polarization direction, compared to... Figures 4 to 9 The radiating element 11 shown in the diagram has a single polarization direction. Radiating element 12 adds two radiating arms and corresponding feed components. A description of the added radiating arms, feed components, and balun, etc., can be found above. Specifically, radiating element 12 can be mounted on the antenna reflector 2. Radiating element 12 includes a first radiating arm 101, a second radiating arm 102, a third radiating arm 103, a fourth radiating arm 104, a balun 20, a first feed component 301, a second feed component 302, a third feed component 303, and a fourth feed component 304. Optionally, balun 20, first feed component 301, second feed component 302, third feed component 303, and fourth feed component 304 can be collectively referred to as a balun. First radiating arm 101 and second radiating arm 102 can be collectively referred to as a first dipole. Third radiating arm 103 and fourth radiating arm 104 can be collectively referred to as a second dipole.

[0130] The first and second dipoles have different polarization directions. This application considers the x-axis as horizontal and the y-axis as vertical. Figure 10 and Figure 11 The radiation element 12 shown is a radiation element with a dual polarization direction of ±45°.

[0131] The first dipole is used to transmit or receive radio frequency signals in the -45° polarization direction, and the second dipole is used to transmit or receive radio frequency signals in the +45° polarization direction.

[0132] The first dipole, the first feed assembly 301, the second feed assembly 302, and the balun 20 together complete the radio frequency signal transmission in the -45° polarization direction. The specific structure of this part of the radiating unit 12 can be referred to Figures 4 to 6 The structure of the radiation unit 11 shown will not be described in detail here.

[0133] Compared to radiating unit 11, radiating unit 12 adds a polarization direction, namely, the transmission of radio frequency signals in the +45° polarization direction is completed through the third radiating arm 103, the fourth radiating arm 104, the third feed component 303, the fourth feed component 304, and the balun 20.

[0134] In radiation unit 12, balun 20 can serve as the signal ground for the dual polarization direction and can be called balun common ground.

[0135] Similar to radiating element 11, third radiating arm 103 and fourth radiating arm 104 are disposed at the second end of balun 20; the first end of third feed assembly 303 is electrically connected to third radiating arm 103, and the second end of third feed assembly 303 is used for electrical connection to antenna feed network; fourth feed assembly 304 is electrically connected to fourth radiating arm 104, and fourth feed assembly 304 is electrically connected to balun 20 by coupling.

[0136] like Figure 10 or Figure 11 As shown, the third power supply component 303 and the second power supply component 302 are disposed on the same side of the balun 20, while the fourth power supply component 304 and the first power supply component 301 are disposed on the other side of the balun 20. Alternatively, in some other implementations, the third power supply component 303 and the second power supply component 302 may not be disposed on the same side of the balun 20, and similarly, the fourth power supply component 304 and the first power supply component 301 may not be disposed on the same side of the balun 20. This application does not limit this. For example, the first power supply component 301 and the third power supply component 303 are disposed on the same side of the balun 20, while the second power supply component 302 and the fourth power supply component 304 are disposed on the other side of the balun 20. Yet another example: the first power supply component 301 and the second power supply component 302 are disposed on the same side of the balun 20, while the third power supply component 303 and the fourth power supply component 304 are disposed on the other side of the balun 20.

[0137] The second end of the third feed component 303 is electrically connected to the antenna feed network, which can be understood as: the second end of the third feed component 303 is electrically connected to the phase shifter of the feed network.

[0138] The third power supply component 303 enables electrical connection between the power supply network and the radiation unit 1, that is, it enables electrical connection between the power supply network and the first radiation arm 104.

[0139] Furthermore, the fourth radiating arm 104 can be grounded via the fourth feed assembly 304. Specifically, the fourth radiating arm 104 is electrically connected to the fourth feed assembly 304, the fourth feed assembly 304 is electrically connected to the balun 20 via coupling, and the balun 20 is electrically connected to the reflector 2, thereby achieving an electrical connection between the fourth radiating arm 104 and the reflector 2. Since the reflector 2 is grounded, the fourth radiating arm 104 is also grounded. The fourth feed assembly 304 can receive radio frequency signals from the balun 20 via coupling and then transmit these signals to the fourth radiating arm 104; alternatively, the fourth feed assembly 304 can receive radio frequency signals from the fourth radiating arm 104 and transmit them to the balun 20 via coupling.

[0140] The second dipole can both transmit and receive electromagnetic wave signals.

[0141] In one implementation, the second dipole can be used to transmit electromagnetic wave signals. In this case, the feed network can transmit a radio frequency signal to the third feed component 303, which can then be transmitted to the third radiating arm 103 and excite a radio frequency current on the fourth radiating arm 104, thereby generating an electromagnetic wave signal on the second dipole.

[0142] In another implementation, the second dipole can be used to receive electromagnetic wave signals. In this case, the second dipole receives the electromagnetic wave signals and transmits them to the feed network via the third feed component 303.

[0143] Through the aforementioned balun 20, third feed component 303, and fourth feed component 304, radio frequency signal transmission between the second dipole and the feed network can be realized, and electromagnetic wave signals can be sent or received through the second dipole.

[0144] In one implementation, the fourth power supply component 304 is electrically connected to the balun 20 via capacitive coupling. Specifically, the structure of the capacitive coupling between the fourth power supply component 304 and the balun 20 can be referred to... Figure 6 The capacitive coupling structure between the second power supply component 302 and the balun 20 will not be described in detail here.

[0145] Similarly, a fourth dielectric layer is included between the balun 20 and the fourth feed assembly 304.

[0146] Optionally, the fourth dielectric layer can be an intangible dielectric layer or a tangible dielectric layer, without limitation. For example, the fourth dielectric layer can be an air layer, or a dielectric layer made of other materials, such as plastics, epoxy resins, and / or ceramics, etc., which are not limited in this application.

[0147] In some implementations, the fourth feed component 304 can be a feed sheet in the form of a microstrip line (also known as a feed wire). Optionally, the fourth feed component 304 can be a serpentine line, a straight line, a gradient line, or other microstrip lines of arbitrary shape. This application does not limit the specific shape of the microstrip line.

[0148] Optionally, the fourth power supply component may also be referred to as a coupling power supply line, a coupling power supply plate, or other terms, without limitation.

[0149] The second power supply component 302 and the fourth power supply component 304 may have the same or different shapes, and there is no restriction.

[0150] Similarly, the effect of capacitive coupling between the fourth power supply component 304 and the balun 20 is related to the area of ​​the fourth power supply component 304. This application does not limit the area and shape of the fourth power supply component 304, as long as capacitive coupling between the fourth power supply component 304 and the balun 20 can be achieved.

[0151] For example, if the fourth feed component 304 is a serpentine feed piece, the length of the feed piece can be approximately equal to the equivalent electrical length, and the length of the serpentine line can be one-quarter of the operating wavelength. Here, the operating wavelength is the operating wavelength of the first dipole and the second dipole. For example, if the operating wavelength is 'a', the length of the feed piece can be approximately a / 4, where 'a' is greater than 0. As another example, if the operating wavelength is a wavelength range, the length of the feed piece can be a value determined according to that wavelength range, for example, one-quarter of the center value of that wavelength range. For instance, if the operating wavelength range is from 'a' to 'b', the length of the feed piece can be approximately [(a+b) / 2] / 4, where 'a' and 'b' are greater than 0, and 'b' is greater than 'a'.

[0152] In some implementations, a dielectric layer is included between the balun 20 and the third power supply assembly 303. Optionally, this dielectric layer can be an air layer or a dielectric layer made of other materials, such as plastic, epoxy resin, ceramic, etc., which is not limited in this application. The third power supply assembly 303 can also be fixed to the balun 20 by a mounting component or the dielectric layer.

[0153] In the aforementioned radiating elements 11 and 12, the feed assembly and the radiating arm are electrically connected via direct connection. It should be understood that the feed assembly and the radiating arm can also be electrically connected via coupling. This coupled electrical connection is applicable to both single-polarized and dual-polarized radiating elements. The following section uses a dual-polarized radiating element as an example, combined with... Figures 12 to 14 This section describes the electrical connection between the power supply assembly and the radiating arm, outlining the coupling method.

[0154] Figure 12 This is a schematic diagram of another type of radiating unit 1 (hereinafter referred to as radiating unit 13). Similar to radiating unit 12, radiating unit 13 also includes a balun 20, four radiating arms (first radiating arm 101, second radiating arm 102, third radiating arm 103, and fourth radiating arm 104) and corresponding feeding components (first feeding component 301, second feeding component 302, third feeding component 303, and fourth feeding component 304). The connection relationships between the components can be referred to in radiating unit 12, and will not be described again here.

[0155] It should be understood that the difference between radiating unit 13 and radiating unit 12 is that in radiating unit 13, the power supply component and the radiating arm can be electrically connected by coupling.

[0156] like Figure 12 As shown, one end of the first power supply component 301 is electrically connected to the first radiation arm 101 by coupling, and / or, one end of the first power supply component 302 is electrically connected to the first radiation arm 102 by coupling, and / or, one end of the first power supply component 303 is electrically connected to the first radiation arm 103 by coupling, and / or, one end of the first power supply component 304 is electrically connected to the first radiation arm 104 by coupling.

[0157] In some implementations, the above coupling is capacitive coupling. The structure of the radiating element 13 is described below using capacitive coupling between the feed component and the radiating arm as an example.

[0158] For example, one end of the power supply component and the corresponding radiating arm are electrically connected by capacitive coupling. This can be understood as follows: one end of the power supply component forms a horizontal plane by bending, and the radio frequency signal is transmitted between the horizontal plane and the radiating arm by capacitive coupling.

[0159] Figure 13 yes Figure 12 The left view, that is, the view observed along the x-axis.

[0160] like Figure 13 As shown, one end of the second power supply component 302 is bent to form a horizontal surface 3021, which is parallel to the second radiating arm 102, thereby enabling capacitive coupling between one end of the second power supply component 302 and the second radiating arm 102.

[0161] In some implementations, a dielectric layer 403 (i.e., an example of a third dielectric layer) is included between one end of the second power supply component 302 and the second radiating arm 102. For example, the dielectric layer 403 can be an air layer or a dielectric layer of other materials, such as plastic, epoxy resin, ceramic, etc., which are not limited in this application.

[0162] It should be understood that one or more (or described as part or all) of the four radiating arms in the radiating element 13 can be electrically connected to the corresponding feed component through coupling. This application does not limit the specific number of radiating arms in the radiating element 13 that are electrically connected to the corresponding feed component through coupling. Furthermore, this application does not limit the method of coupling.

[0163] For example, one end of the first power supply component 301 and the first radiating arm 101 can also be electrically connected by capacitive coupling. Optionally, a dielectric layer (i.e., an example of a second dielectric layer) is included between one end of the first power supply component 301 and the first radiating arm 101.

[0164] For example, one end of the third power supply component 303 and the third radiating arm 103 can also be electrically connected by capacitive coupling. Optionally, a dielectric layer (i.e., an example of a fifth dielectric layer) is included between one end of the third power supply component 303 and the third radiating arm 103.

[0165] For example, one end of the fourth feed component 304 and the fourth radiating arm 104 can also be electrically connected by capacitive coupling. Optionally, a dielectric layer (i.e., an example of a sixth dielectric layer) is included between one end of the fourth feed component 304 and the fourth radiating arm 104.

[0166] The aforementioned radiating element 13 is a radiating element in a dual-polarization direction. Similarly, in a radiating element in a single-polarization direction, the radiating arm and the corresponding feeding component can also be electrically connected by coupling, which will not be elaborated here.

[0167] In the above embodiments, Figures 3 to 13 The radiating arms of the radiating units shown in the illustration are all square annular radiating arms, but this application does not limit the specific shape and structure of the radiating arms. For example, the radiating arms can also be rectangular, circular, or strip-shaped, and can be sheet-like or hollow annular, without limitation.

[0168] For example, Figure 14 This is a schematic diagram of a dual-polarization radiating unit 1 (referred to as radiating unit 14), in which the radiating arms are all strip-shaped sheet-like radiating arms.
