Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

In this application, unless expressly stated or limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can include, for example, fixed connections, removable connections, or integral parts; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.

The antenna assembly is a functional assembly for transmitting or receiving electromagnetic waves, and can be applied to a base station antenna. The antenna assembly generally includes a reflector and a cover plate covering the reflector, and the reflector and the cover plate need to be tightly combined, so that the installation and connection between the reflector and the cover plate are inconvenient.

In order to solve this problem, the inventors have tried to provide an isolation rib on the reflector plate, which not only can serve as an isolation function (for example, isolating two adjacent antennas, but also, for example, isolating the oscillator of the antenna from the feed network), but also can connect the cover plate with the isolation rib (for example, welding, screwing, riveting, etc.) when the cover plate is covered on the reflector plate, and can serve as a support and reinforcement function for the cover plate.

However, in the creation process of the present invention, the inventor finds that, in order to tightly combine the cover plate and the reflection plate, the cover plate needs to be in complete contact with each part of the isolation rib, that is, a relatively complex installation operation needs to be performed, for example, when a welding mode is adopted, a plurality of points need to be welded on each isolation rib, so that a plurality of welding points exist between the cover plate and the isolation rib, and at this time, four hundred to five hundred points may need to be welded to install one antenna, resulting in a relatively low installation efficiency and a relatively high cost. Similarly, when other modes are adopted, multiple times of installation and connection are needed to enable the cover plate to be in complete contact with all parts of the isolation rib, and the installation efficiency is low and the cost is high. The inventor finds that if the isolation rib and the cover plate are only in contact with each other but not fixed with each other, the cover plate is easy to generate extra resonance (the cover plate is thin and easy to deform) once deformed, and the performance of the antenna is seriously affected.

Based on this, in order to solve the technical problem of low efficiency of installation and connection between the reflection plate and the cover plate in the related art, the inventor proposes the following scheme.

Referring to fig. 1 to 4 and fig. 6, an antenna assembly 100 applicable to a base station antenna is provided in the present embodiment, but not limited thereto. The antenna assembly 100 includes a reflector 10, a rib 20, a cover member 30, and an antenna structure 40, wherein:

the reflector 10, i.e., a structural member having a metal material on a surface thereof (the reflector 10 may be made of a metal material, or formed by disposing a metal layer on a surface of a base made of a non-metal material), may reflect the electromagnetic wave signals, so as to facilitate the electromagnetic wave signals to be reflected and collected toward the front (the side where the cover plate 30 is located), enhance the signal transceiving efficiency and sensitivity of the antenna structure 40, and may block and shield the electromagnetic wave signals from the rear (the side away from the cover plate 30), so as to avoid interference with the antenna structure 40. The reflector 10 may be a structure of various shapes, for example, may be a substantially plate-like structure or a disk-like structure; of course, the reflector 10 may also be a shell-like structure or other shaped structure, and is not limited herein.

The ribs 20 are protruding rib structures. The rib 20 includes a convex portion 201 and a convex portion 202, the convex portion 201 is protruded on the reflector 10, and the convex portion 202 is protruded on a side of the convex portion 201 away from the reflector 10. The raised strip portions 201 may be substantially strip-shaped structures, and may be strip-shaped structures with various shapes, such as a linear strip-shaped structure, a bent strip-shaped structure, an arc strip-shaped structure, and the like, but are not limited thereto. The protrusion 202 may be a protrusion structure with various shapes, such as a bump, a boss, etc., but is not limited thereto, and may also be other structures with regular or irregular shapes.

The cover member 30 is covered on the reflector 10 to form a cavity 101 between the reflector 10 and the cover member 30, that is, the surface of the reflector 10 close to the cover member 30 and the surface of the cover member 30 close to the reflector 10 enclose the cavity 101. The cover member 30 may be made of a metal material or a metal layer may be formed on the surface of a base made of a non-metal material, so as to function as a shield in cooperation with the reflector 10. It will be appreciated that the deck member 30 may be a structural member of various shapes, such as a generally plate-like structure; of course, the cover member 30 may have a shell-like structure or other structures, and is not limited herein.

The number of antenna structures 40 is at least one, and may be, for example, one, two, three, four, or more than four. The antenna structure 40 is located within the cavity 101, i.e. between the reflector 10 and the cover member 30. The antenna structure 40 may transmit and receive signals, may be an antenna structure with various shapes, and may be designed according to the actual application requirements, which is not limited herein.

The raised strip 201 and the raised part 202 are both located in the cavity 101, the raised part 202 is connected with the covering plate member 30, and a gap 102 is formed between the part of the raised strip 201 outside the raised part 202 and the covering plate member 30, namely the part of the raised strip 201 outside the raised part 202 is not in contact with the covering plate member 30 and forms the gap 102.

The antenna assembly 100 provided by the embodiment of the application, by providing the reflector 10, the rib 20, the covering plate 30 and the at least one antenna structure 40, the covering plate 30 is covered on the reflector 10 to form the cavity 101 between the covering plate 30 and the reflector 10, the antenna structure 40 is located in the cavity 101, and can receive and transmit signals, the rib 20 includes a convex portion 201 protruding on the reflector 10 and a protruding portion 202 protruding on a side of the convex portion 201 away from the reflector 10, the convex portion 201 and the protruding portion 202 are both located in the cavity 101, the protruding portion 202 is connected to the covering plate 30, and a space 102 is formed between a portion of the convex portion 201 outside the protruding portion 202 and the covering plate 30; therefore, when the cover member 30 is mounted on the reflector 10, the cover member 30 can be connected to the protruding portion 202 of the rib 20 without being connected to the ridge portion 201 of the rib 20, that is, without connecting each portion of the rib 20 to the cover member 30, so that the connection points between the cover member 30 and the rib 20 can be reduced (for example, when welding is adopted, the number of welding points between the cover member 30 and the rib 20 can be reduced), thereby improving the mounting efficiency of the cover member 30 on the reflector 10 and reducing the production cost of the antenna assembly; moreover, since the part of the raised portion 201 outside the protruding portion 202 forms the gap 102 with the covering plate 30, that is, the raised portion 201 does not directly contact with the covering plate 30, the condition that the raised portion 201 is not in contact with the covering plate 30 but is not fixed (in this case, the performance of the antenna assembly is easily affected by extra resonance due to deformation of the covering plate 30 or the reflector 10) can be avoided, so as to reduce the possibility of occurrence of uncontrollable resonance, which is beneficial to improving the performance of the antenna assembly 100.

It is understood that the antenna structure 40 may include a feed network and a radiating element. The required feed network and the required radiation unit can be etched on the circuit board, or the required feed network and the required radiation unit can be electroplated on the plastic part; however, the two schemes have complex process and high cost. Based on this, the inventor adopts the scheme that the metal strip wires comprising the feed network and the antenna elements are cut out from the sheet, and the production and the manufacture are simple and the cost is low. Of course, in other embodiments, the feeding network and the radiating element may be etched or plated on the cover plate 30, or the antenna structure 40 formed by etching or plating in the prior art may be disposed in the cavity 101.

In one embodiment, referring to fig. 2, 5 and 6, the number of the antenna structures 40 is plural, and may be two, three, four or more than four. Each antenna structure 40 is located within the cavity 101. The ribs 20 include at least one partition rib 21, which may be one, two, three or more. Each spacer rib 21 separates adjacent two antenna structures 40. The partitioning rib 21 includes a ridge portion 201 and a projection portion 202.

So set up, because protruding muscle 20 includes the separation muscle 21 that is used for separating adjacent two antenna structure 40, do benefit to and separate into a plurality of sub-cavitys with cavity 101, every antenna structure 40 can be located a sub-cavity. The separating ribs 21 may make the antenna structures 40 relatively independent and not interfere with each other, which is beneficial for the normal operation of the antenna assembly 100. The length of the partition rib 21 is usually longer, and if each part of the partition rib 21 is connected with the covering plate 30, the installation efficiency is lower, but in the embodiment of the present application, the partition rib 21 includes the convex portion 201 and the protruding portion 202, and is connected with the covering plate 30 only through the protruding portion 202, and the convex portion 201 can form the gap 102 between the part outside the protruding portion 202 and the covering plate 30, which is beneficial to improving the installation and connection efficiency between the partition rib 21 and the covering plate 30, and can avoid the phenomenon that the partition rib 21 is not fixed in contact with the covering plate 30 and affects the performance of the antenna assembly 100.

Illustratively, referring to fig. 1, 5 and 6, the antenna assembly 100 includes four antenna structures 40, the rib 20 includes three dividing ribs 21, the three dividing ribs 21 divide the cavity 101 into four sub-cavities, and one antenna structure 40 is located in one sub-cavity.

Of course, in other embodiments, only one antenna structure 40 may be provided, and the separation rib 21 may not be provided.

Alternatively, in an embodiment, referring to fig. 2 and fig. 6, the partition rib 21 includes at least two protrusions 202, and each protrusion 202 is sequentially disposed on the raised strip 201 at intervals.

So set up, because the separation muscle 21 need separate adjacent two antenna structure 40, length needs to set up longer, consequently sets up through a plurality of bellying 202 intervals in proper order, can suitably increase the hookup location between separation muscle 21 and the apron piece 30 and improve the supporting effect to apron piece 30, does benefit to the structural reliability who improves apron piece 30, reduces the possibility of taking place deformation, and then does benefit to the performance that improves antenna module 100.

Alternatively, the distance between two adjacent convex portions 202 ranges from 25mm to 45mm, and may be, for example, 25mm, 26mm, 27mm, 28mm, 29mm, 30mm, 31mm, 32mm, 33mm, 34mm, 35mm, 36mm, 37mm, 38mm, 39mm, 40mm, 41mm, 42mm, 43mm, 44mm, 45mm, and the like, but is not limited thereto.

With such an arrangement, according to the invention, when the distance between two adjacent protrusions 202 ranges from 25mm to 45mm, the possibility of deformation of the deck member 30 can be effectively reduced, and the number of connection points is small.

Of course, in other embodiments, the distance between two adjacent protrusions 202 may also be less than 25mm, or greater than 45 mm.

In other embodiments, only one of the protrusions 202 of the partition rib 21 may be provided.

Optionally, in an embodiment, referring to fig. 2, 5 and 6, the periphery of one side of the reflector 10 close to the cover member 30 is convexly provided with an outer edge structure 11; the outer edge structure 11 is connected to the cover member 30, for example, by welding, but may also be riveted, screwed, etc., but is not limited thereto. The reflector 10, the outer edge structure 11 and the cover member 30 can enclose a cavity 101. Wherein, the outer edge structure 11 and the reflector 10 may be an integrally formed integral structure; of course, in other embodiments, the outer edge structure 11 and the reflector 10 may be formed separately and connected. The protruding height of the protruding strip portion 201 is smaller than the protruding height of the outer edge structure 11.

With this arrangement, the cover member 30 can be connected to the reflector 10 by being connected to the outer edge structure 11, which facilitates the formation of the cavity 101 between the cover member 30 and the reflector 10. Since the protruding height of the protruding strip 201 is less than the protruding height of the rim structure 11, the gap 102 may be formed between the protruding strip 201 and the covering member 30 after the covering member 30 is connected to the rim structure 11.

Optionally, referring to fig. 6, the raised strip portion 201 of the separating rib 21 is connected to the outer edge structure 11, so as to improve the separating effect of the separating rib 21 on the antenna structures 40 on two sides thereof.

It should be noted that, in other embodiments, the outer edge structure may be protruded around the side of the cover member 30 close to the reflector 10, that is, the position of the outer edge structure is changed to the cover member 30. In other embodiments, the outer edge structure 11 may not be provided, and the cover member 30 may be connected to the reflector 10 through other components.

In one embodiment, referring to fig. 3, 5, 6 and 7, the antenna structure 40 includes a feed network 42 and at least one antenna element 41. The feeding network 42 and each antenna element 41 may be an integral structure formed integrally. The number of the antenna elements 41 may be one, two, three, four, or more, and fig. 5 and 7 exemplarily show the case where there are three antenna elements 41. The feed network 42 is connected to each antenna element 41. The ribs 20 include a plurality of isolation ribs 22, for example, two, three, four or more than four isolation ribs; at least two isolation ribs 22 are arranged around the antenna element 41 to separate the antenna element 41 from the feeding network 42. The spacer 22 includes a ridge portion 201 and a projection 202.

In this way, at least two isolation ribs 22 are arranged around the antenna element 41 to separate the antenna element 41 and the feed network 42, so that crosstalk between the antenna element 41 and the feed network 42 can be reduced, and the stability of the antenna structure 40 during operation can be improved. Moreover, the isolation rib 22 includes the raised portion 201 and the protruding portion 202, and the raised portion 202 is connected to the covering plate 30, and it is not necessary that each portion of the isolation rib 22 is connected to the covering plate 30, so that the mounting efficiency of the covering plate 30 on the reflector 10 and the support stability of the covering plate 30 can be further improved, and the gap 102 can be formed between the portion of the raised portion 201 outside the protruding portion 202 and the covering plate 30, so that the performance of the antenna assembly 100 can be prevented from being affected by the condition that the isolation rib 22 is not fixed by contact with the covering plate 30.

For example, referring to fig. 5 and 6, four isolation ribs 22 are arranged around an antenna oscillator 41, and may be substantially square, so as to improve the isolation effect. Of course, in other embodiments, two isolation ribs 22 may be arranged around the antenna element 41, for example, at least one isolation rib 22 may be a bent structure.

Alternatively, in an embodiment, referring to fig. 4 to 6, at least one groove structure 12 is recessed on a side of the reflector 10 close to the cover plate member 30, and the number of the groove structures 12 is the same as the number of the antenna elements 41. The position of each antenna element 41 corresponds to the position of a groove structure 12, i.e. each antenna element 41 is located at a groove structure 12. At least two isolation ribs 22 are disposed around a groove structure 12.

With such an arrangement, since the groove structure 12 is disposed on the reflector 10, and the position of each antenna element 41 corresponds to the position of one groove structure 12, the adjustment range of the distance between the antenna element 41 and the reflector 10 can be increased, which is beneficial to expanding the bandwidth of the antenna assembly 100 by setting the parameters of the groove width, the groove depth and the like of the groove structure 12, and is beneficial to obtaining the required working bandwidth.

Of course, in other embodiments, the groove structure 12 may not be disposed on the reflector 10.

In one embodiment, referring to fig. 4-7, antenna structure 40 includes a feed network 42 and a plurality of antenna elements 41; the feed network 42 includes a first feed line 421 and a second feed line 422, and the first feed line 421 is connected to each antenna element 41; the second feed lines 422 are connected to the antenna elements 41, respectively. The convex rib 20 comprises at least one spacing rib 23, and each spacing rib 23 is located between two adjacent antenna oscillators 41 and between the first feed circuit 421 and the second feed circuit 422 to separate the first feed circuit 421 and the second feed circuit 422; the spacer 23 includes a ridge portion 201 and a projection portion 202.

So configured, the spacer 23 may separate the first feeding line 421 and the second feeding line 422 of the antenna structure 40, so as to reduce crosstalk therebetween. The spacing rib 23 includes the convex portion 201 and the protruding portion 202, and the protruding portion 202 is connected to the covering plate 30, and it is not necessary that each portion of the spacing rib 23 is connected to the covering plate 30, so that the mounting efficiency of the covering plate 30 on the reflector 10 and the support stability of the covering plate 30 can be further improved, and the gap 102 can be formed between the portion of the convex portion 201 outside the protruding portion 202 and the covering plate 30, thereby avoiding the influence on the performance of the antenna assembly 100 caused by the unfixed condition of the contact between the spacing rib 23 and the covering plate 30.

In other embodiments, the spacer 23 may not be provided.

In one embodiment, the boss 202 is welded to the deck member 30. For example, laser welding may be employed; of course, in other embodiments, other welding methods may be used.

So set up, bellying 202 is connected through adopting the welded mode with apron piece 30, and not only the connection is convenient, connects comparatively firmly moreover.

Optionally, when laser welding is adopted, welding can be carried out by adopting a laser welding tool, the laser welding tool can comprise a plate body and through holes arranged on the plate body, and the number and the positions of the through holes can be set according to the positions to be welded; during welding, the laser welding tool can be arranged above the cover plate piece 30, and the welding equipment can weld the required welding points through the through holes in the plate body.

In one embodiment, the reflector 10 is a metal reflector 10 made of a metal material, i.e. all of the metal material, such as copper, aluminum, iron, etc., but not limited thereto, and may be an alloy.

With such an arrangement, since the reflector 10 is made of a metal material, the reflection effect is good, and the structural strength of the reflector 10 is improved, so as to improve the structural reliability of the antenna assembly 100.

In one embodiment, the cover member 30 is a metal cover member 30 made of a metal material, i.e., a metal material, such as, but not limited to, copper, aluminum, iron, etc., but may also be an alloy.

So set up, because the apron piece 30 is all made for metal material, its reflection effect is better, and does benefit to the structural strength who improves apron piece 30, and then does benefit to the structural reliability who improves antenna module 100.

In one embodiment, please refer to fig. 2 and 6, the ridge 201 and the reflector 10 are an integral structure, that is, the ridge 201 and the reflector 10 are integrally formed, so as to facilitate the formation of the ridge 201.
