[0057] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0058] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the specific implementation methods of the present application will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0059] In order to simplify the drawings, only the parts related to the invention are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked. In this article, "one" not only means "only one", but also means "more than one".

[0060] It should be further understood that the term “and / or” used in the specification and appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0061] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0062] In the embodiments shown in the drawings, the indications of directions (such as up, down, left, right, front and back) used to explain the structure and movement of various devices of the present application are not absolute but relative. These descriptions are appropriate when these devices are in the positions shown in the drawings. If the descriptions of the positions of these devices change, the indications of these directions also change accordingly.

[0063] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0064] At present, in order to meet communication needs and save site resources, major manufacturers in the industry have released integrated base station antenna solutions, that is, adding additional active antenna units or other types of communication equipment to the original base station antenna. Among them, the base station antenna is installed with a reflector as the main body. The stress and deformation of the reflector is currently one of the most important factors affecting the intermodulation failure and instability of the antenna.

[0065] Therefore, a frame structure with sufficient rigidity and strength is set in the base station antenna, and the reflector assembly and other components in the antenna are set on the frame, which can increase the rigidity and strength of the reflector assembly, avoid deformation of the reflector assembly due to external factors, and improve the antenna intermodulation level and stability.

[0066] In this regard, the present application provides an antenna assembly 100, see Figures 1 to 9 , including an antenna housing 110, a passive unit 120 and a fixing frame 130. An assembly space is formed in the antenna housing 110, and the passive unit 120 is fixed in the assembly space by the fixing frame 130. At the same time, a mounting position is provided on a side of the fixing frame 130 away from the passive unit 120 for docking with an active unit or an external communication device.

[0067] In this embodiment, by setting a fixed frame 130 to install the passive unit 120, the structural stability and structural strength of the antenna assembly 100 can be improved, so that the antenna assembly 100 and its internal structure are not easily deformed by external factors. Specifically, the antenna assembly 100 provided in this embodiment is a passive antenna assembly 100, and the antenna cover 110 is also provided with an antenna reflector, a phase-shifted feeding structure, an antenna vibrator, a connector panel, an electric adjustment and other auxiliary materials. When an active unit or an external communication device is installed on the antenna assembly 100, the antenna assembly 100 is not prone to stress concentration and structural deformation, so that the performance of the antenna assembly 100 no longer deteriorates or deteriorates less significantly, which can effectively improve the antenna intermodulation level and stability. In addition, the fixed frame 130 in this embodiment can also be installed with an active unit or an external communication device, and the product structure is simple and highly integrated.

[0068] For example, see Figures 1 to 3 , Figure 8 and Fig. 9 , the fixing frame 130 is disposed outside the antenna housing 110, and the antenna housing 110 is provided with a first avoidance hole for the passive unit 120 to be fixed to the fixing frame 130; or, see Figures 4 to 7 The fixing frame 130 is arranged in the assembly space of the antenna cover 110, and the antenna cover 110 is provided with a second avoidance hole 111 at least corresponding to the installation position, so that the active unit or the external communication device can be fixed to the fixing frame 130.

[0069] In this embodiment, the fixed frame 130 can be arranged outside the antenna housing 110 or inside the antenna housing, and the layout is flexible and convenient, and can be flexibly arranged according to actual conditions, and is highly practical. In addition, in this embodiment, the active unit (or external communication device) and the passive unit 120 are arranged on opposite sides of the fixed frame 130.

[0070] In one example embodiment, see Figure 2 , Fig.10 and Fig.11 The fixing frame 130 includes two longitudinal beams 131, both of which extend along the length direction of the antenna housing 110, and the two longitudinal beams 131 are arranged in sequence along the width direction of the antenna housing 110. Among them, both of the longitudinal beams 131 are provided with a plurality of first fixing holes, and the plurality of first fixing holes are arranged in sequence along the length direction of the longitudinal beams 131.

[0071] In this embodiment, the first fixing hole can be directly used as an assembly hole to connect the active unit or external communication device to form the above-mentioned installation position. In this way, when performing the installation operation, the assembler only needs to match the installation structure on the active unit or external communication device with the first fixing hole on the fixing frame 130, and tighten it with the fastener to complete the installation, which effectively solves the problem of cumbersome assembly process of the active unit or external communication device.

[0072] In addition, there are multiple first fixing holes set on the longitudinal beam. When installing, the assembler can select the first fixing hole at the corresponding position according to the size of different active units or external communication devices. For example, when installing an active unit or external communication device with a shorter length, the first fixing hole with a closer distance can be selected for fixing; when installing an active unit or external communication device with a longer length, the first fixing hole with a farther distance can be selected for fixing. The layout is flexible and adaptable.

[0073] In the above embodiment, the longitudinal beam 131 can be made of metal or non-metal material and manufactured by pultrusion or injection molding.

[0074] In one embodiment, see Figures 1 to 5 and Figures 7 to 9 The fixing frame 130 further includes a mounting bracket 134. In this case, the first fixing hole can be used to install the mounting bracket 134, and the mounting bracket 134 forms the above-mentioned mounting position for fixing the active unit or the external communication device. Specifically, the mounting bracket 134 is provided with fourth fixing holes at both ends in the length direction, and the fastener passes through the fourth fixing hole and the first fixing hole to lock the mounting bracket 134 to the longitudinal beam 131.

[0075] Of course, see Figures 1 to 5 and Figure 7 In actual production, the mounting bracket 134 can also be used to fix other external structures, which are not described here one by one and are all within the protection scope of this application.

[0076] For example, see Figure 2 and Figures 10 to 14 The fixed frame 130 further includes two main cross beams 132, and both ends of the two main cross beams 132 in the length direction are provided with a first docking block 1321 and a second docking block 1322. At this time, the longitudinal beam 131 is provided with a first cavity 1313 and a second cavity 1314, and the first cavity 1313 and the second cavity 1314 both extend along the length direction of the longitudinal beam 131 to both ends of the longitudinal beam 131 in the length direction.

[0077] In this embodiment, the first docking block 1321 is provided in the first cavity 1313, the second docking block 1322 is provided in the second cavity 1314, and the first docking block 1321 or the second docking block 1322 is provided with a second fixing hole 1323, and the longitudinal beam 131 is provided with a third fixing hole, and the fastener passes through the second fixing hole 1323 and the third fixing hole to lock the main cross beam 132 to the longitudinal beam 131. The main cross beam 132 can be made of metal or non-metal material and is made by pultrusion or injection molding.

[0078] By providing two main beams 132, this embodiment can improve the structural strength and stability of the fixing frame 130 to a certain extent, reduce the risk of deformation of the antenna assembly 100, thereby reducing the performance degradation of the antenna assembly 100 caused by the installation of active units or external communication equipment, and improve the antenna intermodulation level and stability. Fig.12 In this embodiment, a reinforcing rib 1319 may be formed between the first cavity 1313 and the second cavity 1314 to improve the structural strength of the longitudinal beam 131 , thereby improving the structural strength of the fixed frame 130 .

[0079] Specifically, the first docking block 1321 is arranged close to the passive unit 120, and the second fixing hole 1323 is provided on the first docking block 1321, and the third fixing hole is provided on one side of the longitudinal beam 131 for installing the passive unit 120. In this way, the provision of the third fixing hole will not affect the arrangement of the first fixing hole 1311 and the second hole position 1312, and the structural setting is reasonable and practical.

[0080] In one example embodiment, see Fig.13 The longitudinal beam 131 is provided with a third cavity 1315 and a fourth cavity 1316, and the third cavity 1315 and the fourth cavity 1316 are extended to both ends of the longitudinal beam 131 in the length direction of the longitudinal beam 131. At the same time, a phase shifting circuit board 1317 is provided in the third cavity 1315 and the fourth cavity 1316, and a phase shifting medium 1318 is provided on the phase shifting circuit board 1317, and the phase shifting medium 1318 can slide relative to the phase shifting circuit board 1317.

[0081] In this embodiment, a phase-shift feeding structure can be formed by arranging a third cavity 1315 and a fourth cavity 1316 on the longitudinal beam 131, and arranging a phase-shift circuit board 1317 and a phase-shift medium 1318 in the third cavity 1315 and the fourth cavity 1316, so that the function of the cavity phase shifter is integrated on the longitudinal beam 131, and the structural integration is high. At this time, the third cavity 1315 and the fourth cavity 1316 are positive and negative polarization cavities.

[0082] It is worth noting that in order to form a phase-shifted feeding network and feed the antenna element, the longitudinal beam 131 provided in this embodiment should be made of metal material with high structural strength and good conductivity. In addition, the longitudinal beam 131 provided in this embodiment should be arranged inside the antenna cover 110. In this case, there is no need to set a phase-shifted feeding structure in the antenna cover 110, and the structural setting is more reasonable and practical.

[0083] In one example embodiment, see Figure 2 , Fig.10 and Fig.15The fixed frame 130 further includes a secondary cross beam 133. The number of the secondary cross beam 133 is at least one, and the two ends of the secondary cross beam 133 in the length direction are respectively fixed to the two longitudinal beams 131. The secondary cross beam 133 can be made of metal or non-metal material and is made by pultrusion or injection molding.

[0084] By setting the secondary crossbeam 133, this embodiment can improve the structural strength and stability of the fixed frame 130 to a certain extent, reduce the risk of deformation of the antenna assembly 100, thereby reducing the performance deterioration of the antenna assembly 100 caused by the installation of active units or external communication equipment, and improve the antenna intermodulation level and stability.

[0085] Specifically, see Fig.10 and Fig.15 The secondary cross beam 133 is provided with fifth fixing holes 1331 at both ends in the length direction, and the longitudinal beam 131 is provided with a sixth fixing hole 311 on one side for mounting the passive unit 120 , and the fastener passes through the fifth fixing hole 1331 and the sixth fixing hole 311 to lock the secondary cross beam 133 to the longitudinal beam 131 .

[0086] In one example embodiment, see Figures 1 to 10 The antenna assembly 100 includes an antenna housing 110, a passive unit 120 and a fixing frame 130, and the fixing frame 130 includes two longitudinal beams 131, two main transverse beams 132 and at least two mounting brackets 134, and a secondary transverse beam 133 is provided between the two longitudinal beams 131. Among them, a plurality of first fixing holes are provided on the two longitudinal beams 131, and the first fixing holes on the two longitudinal beams 131 are arranged one by one.

[0087] In this embodiment, the first fixing holes on each longitudinal beam 131 can be divided into a first hole position 1311 and a second hole position 1312. The first hole positions 1311 on the two longitudinal beams 131 form two groups of first hole groups, each of which includes four first hole positions 1311, and the four first hole positions 1311 are arranged in pairs on the two longitudinal beams 131; correspondingly, the second hole positions 1312 on the two longitudinal beams 131 form four groups of second hole groups, each of which includes four second hole positions 1312, and the four second hole positions 1312 are arranged in pairs on the two longitudinal beams 131.

[0088] Specifically, the two first hole groups are arranged in the middle section of the fixed frame 130, and the four second hole groups are arranged in pairs at both ends of the fixed frame 130 in the length direction. At this time, the number of the secondary beams 133 is preferably two, and the two secondary beams 133 are located between the two first hole groups.

[0089] See also Figures 1 to 10 , Fig.16 and Fig.17The antenna assembly 100 in this embodiment is used to connect two external communication devices, namely, a first communication device 210 and a second communication device 220. The first communication device 210 and the second communication device 220 are both provided with a docking portion 310, which is the mounting structure on the external communication device mentioned in the above embodiments, and a sixth fixing hole 311 is provided on the docking portion 310.

[0090] In this embodiment, the first communication device 210 and the second communication device 220 can be directly fixed to the fixed frame 130 through the first fixing hole on the longitudinal beam 131. Specifically, the sixth fixing hole 311 on the first communication device 210 can be matched with the first hole position 1311 in a first hole group and the second hole position 1312 in the second hole group close to the first hole group, and the first communication device 210 is locked to the fixed frame 130 by a fastener. Relatively speaking, the sixth fixing hole 311 on the second communication device 220 is matched with the first hole position 1311 in another first hole group and the second hole position 1312 in the second hole group close to the first hole group, and the second communication device 220 is locked to the fixed frame 130 by a fastener.

[0091] At this time, see Figures 1 to 7 There are two mounting brackets 134 , which are fixed to both ends of the two longitudinal beams 131 in the length direction through second holes 1312 close to the ends of the longitudinal beams 131 for docking with the external structure.

[0092] Of course, in actual production, see Figure 8 and Fig. 9 , the first communication device 210 and the second communication device 220 can also be fixed to the fixed frame 130 through the mounting bracket 134. At this time, the number of the mounting brackets 134 is three, namely the first mounting bracket 1341, the second mounting bracket 1342 and the third mounting bracket 1343. Among them, the first mounting bracket 1341 and the third mounting bracket 1343 are fixed to the two ends of the two longitudinal beams 131 in the length direction through the second hole position 1312 close to the end of the longitudinal beam 131, and the second mounting bracket 1342 is fixed to the longitudinal beam 131 through the first hole position 1311 according to actual conditions. At this time, the docking portion 310 on the first communication device 210 can cooperate with the first mounting bracket 1341 and the second mounting bracket 1342, and the first communication device 210 is locked to the fixed frame 130 by using fasteners. Relatively, the docking portion 310 on the second communication device 220 cooperates with the second mounting bracket 1342 and the third mounting bracket 1343, and the second communication device 220 is locked to the fixed frame 130 by using fasteners.

[0093] Alternatively, see Fig.18 and Fig.19, the number of mounting brackets 134 is two, which are respectively fixed to the two ends of the length direction of the fixed frame 130 through the two second hole groups near the ends of the fixed frame 130. At this time, the sixth fixing hole 311 on the first communication device 210 cooperates with the first hole position 1311 in one of the first hole groups and the mounting bracket 134 near the first hole group, and the first communication device 210 is locked to the fixed frame 130 by a fastener.
