Description

Technical Field

[0001] The present invention relates to the field of touch control technology, and in particular to a feeding network component, a phase shifter, and an antenna device. Background Art

[0002] The feed network is the core component of the base station antenna, and its function is to change the phase of the radiating unit to achieve the downtilt of the antenna beam. Figure 1A As shown, the feeding network in the related art includes a transmission structure and a closed metal cavity, and the transmission structure includes a strip line and a phase-shifting medium, wherein the strip line is located in the middle of the upper and lower metal floors, and the phase-shifting medium is located on both sides of the strip line and between the strip line and the metal floor. The closed metal cavity is usually made of profiles or sheet metal, and the adjacent two walls of the four walls are directly connected to form a cavity structure with four sides closed, so as to constrain the electric field inside the feeding network from radiating outward. However, in this method, the cavity processing cost is high. In order to reduce costs, other related technologies use capacitive coupling to construct the accommodating cavity, but in this method, the capacitive coupling is achieved due to the relative arrangement of the metal plates, so resonance will be formed in the relative areas of the metal plates, affecting the transmission efficiency. Summary of the invention

[0003] The purpose of the present invention is to provide a feeding network component, a phase shifter, and an antenna device to solve the technical problems in the prior art.

[0005] In the present application, by providing slots in the first sub-side wall and the second sub-side wall that are oppositely arranged and capacitively coupled, the oppositely arranged area is reduced, thereby reducing resonance and improving transmission efficiency.

[0006] In some possible embodiments, the first side wall is a side wall of the accommodating cavity, and the first sub-side wall is integrally connected to the side wall of the accommodating cavity.

[0007] In the present application, a variety of configuration modes of the first sub-side wall are provided, making the present application more universal.

[0008] In some possible embodiments, in the first sub-sidewall and the second sub-sidewall that are oppositely arranged and capacitively coupled, the first sub-sidewall includes at least two first grooves and the second sub-sidewall includes at least two second grooves; the first grooves and the second grooves are alternately arranged.

[0009] In the present application, when there are a large number of slots, the slots may be arranged in a staggered manner, thereby ensuring the stability of the feed network component.

[0013] In the present application, the accommodating cavity can be divided into multiple sub-accommodating cavities by setting an intermediate baffle, so that the transmission structures in different sub-accommodating cavities can be connected to the radiating units of different polarizations of the antenna device, and then the needs of radiating units of different polarizations can be met by one feeding network, thereby simplifying the structure of the feeding network and reducing costs.

[0014] In some possible embodiments, the target end is disposed opposite to the side wall of the accommodating chamber, and at least one of the oppositely disposed target end and the side wall of the accommodating chamber includes at least one slot; the target end is an end of the intermediate baffle coupled to the side wall of the accommodating chamber.

[0015] In the present application, by providing slots in the target end and the side wall of the accommodating cavity that are relatively arranged and capacitively coupled, the relatively arranged area is reduced, thereby reducing resonance and improving transmission efficiency.

[0016] In some possible embodiments, in the target end and the side wall of the accommodating cavity that are arranged opposite to each other, the target end includes at least two third slots, and the side wall of the accommodating cavity includes at least two fourth slots; the third slots and the fourth slots are arranged alternately.

[0024] In some possible embodiments, the length of the slot along the first direction is less than half of an operating wavelength, where the operating wavelength is an operating wavelength of an antenna device corresponding to the feed network component.

[0025] In the present application, by setting the distance between adjacent slots to be smaller than the preset distance, the metal on both sides of the slots is prevented from forming a coupled connection due to the gap in the middle, thereby preventing resonance, thereby further ensuring the transmission efficiency.

[0064] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, but should not be construed as limiting the present invention.

[0065] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0066] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0067] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0068] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0069] The embodiment of the present application provides an antenna device that can be applied to a communication device, wherein the communication device can be a communication base station such as a public mobile communication base station. The communication device such as a communication base station is an interface device for a mobile device to access the Internet, and is also a form of a radio station. In a certain radio coverage area, information can be transmitted between the communication base station (mobile communication exchange center) and the mobile device.

[0070] Among them, the main component for information transmission between communication base stations and mobile devices is the antenna system. Figure 1B As shown, the antenna system 1 may include an antenna device 10, a fixing bracket 20, a pole 30, and a grounding device 40, wherein the antenna device 10 is fixed to the pole 30 by the fixing bracket 20. In practical applications, the position and angle of the fixing bracket 20 may be adjusted to adjust the position and installation angle of the antenna device 10 on the pole 30.

[0071] In addition, one end of the antenna device 10 can also be connected to the grounding device 40 through a connector to ensure that the antenna device 10 is grounded. Wherein, one end of the connector connected to the antenna device 10 and one end of the connector connected to the grounding device 40 are both provided with joint seals to ensure the sealing of the connection between the two ends of the connector and the antenna device 10 and the grounding device 40 respectively. It can be understood that the joint seal can be an insulating sealing tape such as a polyvinyl chloride (PVC) insulating tape.

[0072] In specific applications, the antenna device 10 is usually located in a radome. The radome is a cover structure outside the antenna device 10. The radome is a structural component that protects the antenna device 10 from the external environment. It has good electromagnetic wave penetration characteristics in electrical performance and can withstand the effects of the external harsh environment in mechanical performance. The antenna device 10 is protected by the radome to prevent the antenna device 10 from being damaged by dust or water.

[0073] like Figure 2As shown, the antenna device 10 of the embodiment of the present application may include at least one independent array composed of a radiation unit 11 and a reflector 17, wherein the frequencies of the radiation units 11 may be the same or different, and the radiation units 11 are usually placed above the reflector 17, and the array receives or transmits radio frequency signals through respective feed network components 100. The antenna device 10 may also include a phase shifter 12 connected to the radiation unit 11, wherein the phase shifter 12 is used to achieve real-time variability of network coverage, and adjust the signal phase to achieve electrical downtilt of the array antenna.

[0074] The feed network component 100 is disposed in the phase shifter 12, and the feed network component 100 is electrically connected to the radiation unit 11 and the antenna connector 16. The feed network component 100 can feed the radio frequency signal to the radiation unit 11 according to a certain amplitude and phase, or send the received radio signal to a radio frequency device such as a signal processing unit of a communication base station according to a certain amplitude and phase.

[0075] Exemplarily, one end of the antenna connector 16 away from the feeding network can be electrically connected to a radio frequency circuit (not shown in the figure), so that radio frequency signals can be transmitted between the radiation unit 11 and the radio frequency circuit. For example, the other end of the antenna connector 16 is electrically connected to a radio frequency signal port in the radio frequency circuit.

[0076] Among them, when the antenna device is a transmitting antenna, the RF circuit can provide a signal source for the antenna device. For example, the other end of the antenna connector 16 can be electrically connected to the RF signal port in the RF circuit, that is, the feeding network component 100 is electrically connected to the RF signal port in the RF circuit, so that the RF signal port can send a RF signal and feed the RF signal into the radiation unit 11 in the form of current, and then the radiation unit 11 sends the RF signal in the form of electromagnetic waves and is received by the receiving antenna in the mobile device.

[0077] When the antenna device is a receiving antenna, the RF circuit can receive the RF signal fed back by the antenna device. For example, the radiation unit 11 of the antenna device converts the received electromagnetic wave signal into a current signal, which is then transmitted to the RF circuit through the feeding network component 100, and then subsequently processed by the signal processing unit.

[0078] The radio frequency circuit includes a remote radio unit (RRU), which is a part of the radio frequency circuit of the remote radio unit, and the radio frequency signal port is generally arranged in the remote radio unit. The specific circuit setting and working principle of the radio frequency circuit can be directly referred to the relevant content of the prior art, and will not be repeated here.

[0079] In practical applications, with the widespread application and development of 5G technology, base station antennas are developing towards multi-band and multi-array, and the integration of antenna devices is getting higher and higher. For example, the antenna device may include multiple radiating units 11 and multiple feeding network components 100, and the feeding network components 100 are arranged one-to-one with the radiating units 11, so that the antenna device forms an array antenna. Each radiating unit 11 is electrically connected to the corresponding feeding network component 100, so that each radiating unit 11 is electrically connected to the RF circuit through its own feeding network component 100, so that each radiating unit 11 receives or sends a RF signal.

[0080] In addition, in some embodiments, the feed network component 100 can also be connected to a transmission component (not shown in the figure) to achieve different radiation beam pointing; or, the feed network component 100 can also be connected to a calibration network to obtain the calibration signal required by the system. In addition, a module for expanding performance such as a combiner 15 or a filter 14 can be provided between the feed network component 100 and the antenna connector 16 to improve the performance of the antenna device 10. The embodiment of the present application does not further limit the phase shifter 12, the filter 14, the calibration network 13 and the combiner 15.

[0081] The following is a detailed description of the feed network assembly 100 provided in the embodiment of the present application in conjunction with the accompanying drawings:

[0082] For the convenience of description, in the embodiment of the present application, the length direction of the feed network component 100 is set as the first direction, the thickness direction is set as the second direction, and the direction perpendicular to the first direction and the second direction is the third direction.

[0083] like Figure 3 As shown, it is a schematic diagram of the structure of the feeding network component 100; Figure 4 The three-dimensional view of the feed network component 100 is shown; the feed network component 100 includes: a cavity 110 and a transmission structure 120; wherein the cavity includes a receiving cavity 130, and the receiving cavity 130 is used to receive the transmission structure 120; the cavity 110 also includes a first side wall 140, and the first side wall 140 includes a first sub-side wall 1401 and a second sub-side wall 1402 that are oppositely arranged and capacitively coupled, and at least one of the first sub-side wall 1401 and the second sub-side wall 1402 that are oppositely arranged and capacitively coupled includes at least one slot 1403 ( Figure 3 not shown).

[0084] In the present application, by providing slots in the first sub-side wall 1401 and the second sub-side wall 1402 that are oppositely arranged and capacitively coupled, the oppositely arranged area is reduced, thereby reducing resonance and improving transmission efficiency.

[0085] In the embodiments of the present application, Figure 3As shown, the first side wall 140 is the side wall of the accommodating cavity 130, the first sub-side wall 1401 is integrally connected to the side wall of the accommodating cavity 130, and the second sub-side wall 1402 is integrally connected to the side wall of the accommodating cavity 130. That is, the first sub-side wall is extended from the side wall of the accommodating cavity.

[0086] In some possible embodiments, Figure 5 As shown, in the first sub-sidewall 1401 and the second sub-sidewall 1402 which are arranged opposite to each other and capacitively coupled, the first sub-sidewall 1401 includes at least two first grooves 1413 and the second sub-sidewall includes at least two second grooves 1423; the first grooves 1413 and the second grooves 1423 are arranged alternately.

[0087] In the present application, the structure of the feeding network can be made more stable by staggered arrangement of the slots, thereby extending the service life of the feeding network and saving costs.

[0088] In some other possible embodiments, Figure 6 As shown, in the first sub-sidewall 1401 and the second sub-sidewall 1402 which are arranged opposite to each other and capacitively coupled, the first sub-sidewall 1401 includes at least two first grooves 1413 and the second sub-sidewall 1402 includes at least two second grooves 1423; the first grooves 1413 and the second grooves 1423 are arranged opposite to each other.

[0089] In the present application, when grooves are set on both the first sub-side wall and the second sub-side wall, the first groove on the first sub-side wall and the second groove on the second sub-side wall can be set relative to each other or staggered. The present application is more flexible in setting the grooves, making the present application more universal.

[0090] In some possible embodiments, the feed network component 100 further includes: at least one intermediate baffle 150, which is disposed in the accommodating cavity 130, and the intermediate baffle 150 divides the accommodating cavity 130 into at least two sub-accommodating cavities 1301, each of which is provided with a transmission structure 120; at least one end of the intermediate baffle 150 is coupled to the side wall of the accommodating cavity 130.

[0091] In the present application, the accommodating cavity 130 can be divided into a plurality of sub-accommodating cavities 1301 by setting an intermediate baffle 150, so that the transmission structures 120 in different sub-accommodating cavities 1301 can be connected to the radiation units of the antenna device with different polarizations, and then the needs of the radiation units with different polarizations can be met by one feeding network component 100, thereby simplifying the structure of the feeding network component 100 and reducing the cost.

[0092] It should be noted that in the present application, there is no limitation on the number of intermediate baffles 150, that is, one intermediate baffle 150 can be set to divide the accommodating chamber 130 into two sub-accommodating chambers 1301, two intermediate baffles 150 can be set to divide the accommodating chamber 130 into three sub-accommodating chambers 1301, or three intermediate baffles 150 can be set to divide the accommodating chamber 130 into four sub-accommodating chambers 1301, and so on.

[0093] In some possible embodiments, in order to further reduce resonance, the target end 1501 is arranged opposite to the side wall of the accommodating cavity, and at least one of the oppositely arranged target end 1501 and the side wall of the accommodating cavity includes at least one groove; the target end 1501 is an end of the intermediate baffle 150 coupled to the side wall of the accommodating cavity.

[0094] For example: Figure 7 As shown, the setting style of the middle baffle 150 is "L"-shaped, and the lower end of the middle baffle is coupled to the side wall of the accommodating cavity, so the lower end of the middle baffle 150 is the target end.

[0095] In the present application, by providing slots in the target end and the side wall of the accommodating cavity that are relatively arranged and capacitively coupled, the relatively arranged area is reduced, thereby reducing resonance and improving transmission efficiency.

[0096] In some possible embodiments, Figure 8 As shown ( Figure 8 Only the middle baffle and the side wall of the accommodating cavity are shown in the figure. In the target end 1501 and the side wall of the accommodating cavity which are arranged opposite to each other, the target end 1501 includes at least two third grooves 1433, and the side wall of the accommodating cavity includes at least two fourth grooves 1443; the third groove 1433 and the fourth groove 1443 are arranged alternately.

[0097] In the present application, when there are a large number of slots, the slots may be arranged in a staggered manner, thereby ensuring the stability of the feed network component and extending the service life of the feed network component.

[0098] In some other possible embodiments, Fig. 9 As shown, in the target end 1501 and the side wall of the accommodating cavity that are arranged opposite to each other, the target end 1501 includes at least two third slots 1433, and the side wall of the accommodating cavity includes at least two fourth slots 1443; the third slot 1433 and the fourth slot 1443 are arranged opposite to each other.

[0099] In the present application, when slots are set on both the target end 1501 and the side wall of the accommodating cavity, the third slot 1433 on the target end 1501 and the fourth slot 1443 on the side wall of the accommodating cavity can be set relative to each other or staggered. The present application is more flexible in setting the slots, making the present application more universal.

[0100] In some possible embodiments, the intermediate baffle 150 is configured as follows: Figure 7 The "L" shape shown can also be set as Fig.10 The “I” shaped metal structure shown, the connection method of the intermediate baffle 150 of the I-shaped structure and the side wall of the accommodating cavity can be a coupling connection, or can be directly connected by means of screws, etc. When the intermediate baffle 150 of the I-shaped structure is coupled to the side wall of the accommodating cavity, the method of determining the target end of the intermediate baffle and the method of slotting are the same as Figure 7 The same is not repeated here.

[0101] In some other possible embodiments, Fig.11 As shown, the intermediate baffle 150 can also be integrally formed with the lower side wall of the accommodating cavity. In this case, the upper end of the intermediate baffle 150 is the target end 1501, and the groove method of the target end 1501 and the side wall of the accommodating cavity is the same as Figure 7 The same is not repeated here.

[0102] In some other possible embodiments. Fig.12 As shown, the intermediate baffle 150 can also be integrally formed with the upper side wall of the accommodating cavity. In this case, the upper end of the intermediate baffle 150 is the target end 1501. The groove method of the target end 1501 and the side wall of the accommodating cavity is the same as that of Figure 7 The same is not repeated here.

[0103] In some possible embodiments, Fig.13 As shown (taking the slots arranged on the second sub-side wall 1402 as an example), at least one of the first sub-side wall 1401 and the second sub-side wall 1402 that are arranged oppositely and capacitively coupled includes at least two slots arranged along the first direction, and the distance between the adjacent slots along the first direction in the at least two slots arranged along the first direction is a preset distance. The preset distance can be set to an integer multiple of a quarter of the working wavelength, and the working wavelength is the working wavelength of the antenna device corresponding to the feed network component 100.

[0104] In some possible embodiments, Fig.14 As shown, the depth of the groove along the second direction ( Fig.14 w2) is larger than the coupling region ( Fig.14 The width of w1) in the figure; the coupling area is the area of ​​the coupling connection where the slot is located.

[0105] In the present application, by setting the depth of the groove to be greater than the width of the coupling region, the area where the first sub-side wall and the second sub-side wall are arranged opposite to each other is reduced, thereby reducing the resonance.

[0106] In some other possible embodiments, Fig.14 As shown, the length of the slot along the first direction ( Fig.14The l1) in the figure is less than half of the working wavelength, where the working wavelength is the working wavelength of the antenna device corresponding to the feeding network component.
