[0041] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0042] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0043] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0044] The terms "first," "second," and "third" (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0045] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such as a process, method, system, product, or maintenance tool that includes a series of steps or units, not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or maintenance tool.

[0046] With the rapid development of wireless communication technology, wall-mounted antennas are being used more and more widely, and the requirements for lightweight and integrated wall-mounted antennas are also getting higher and higher.

[0047] A wall-mounted antenna consists of a metal substrate, a PCB board, coaxial cables, vibrators, and connectors. There are typically multiple PCB boards, each mounted on the metal substrate with fasteners, and these PCB boards are electrically connected to each other via coaxial cables. There are also typically multiple vibrators, which are connected to the PCB boards via coaxial cables. Connectors are also connected to the PCB boards via coaxial cables.

[0048] The metal substrate is used to support other components in the wall-mounted antenna. Therefore, the metal substrate itself needs to have a certain rigidity. In order to prevent the metal substrate from deforming due to the toughness of the metal itself, the thickness of the metal substrate is usually large, which makes the metal substrate heavy.

[0049] In manufacturing a wall-mounted antenna, multiple PCBs are first mounted on a metal substrate using fasteners. Then, one end of a coaxial cable is soldered to one of the PCBs, and the other end is soldered to another PCB to electrically connect the PCBs. Next, one end of the coaxial cable is soldered to a PCB, and the other end is soldered to a vibrator to electrically connect the vibrator to the PCB. The vibrator also needs to be electrically connected to the metal substrate via a coaxial cable for grounding. Finally, a connector is electrically connected to the PCB via a coaxial cable. The assembly process of a wall-mounted antenna is complex.

[0050] When the PCB is installed on the metal substrate, there are problems such as warping on the PCB, resulting in gaps between the PCB and the metal substrate. The PCBs are electrically connected to each other, between the PCB and the vibrator, between the vibrator and the metal substrate, and between the PCB and the connector via coaxial cables. The arrangement of multiple coaxial cables on the metal substrate is messy and complicated, and there are multiple solder points in the wall-mounted antenna, which makes the signal transmission between the PCB, the vibrator and the connectors relatively lossy.

[0051] Therefore, the assembly process of wall-mounted antennas is complex, and the signal loss between the PCB board, vibrator and connectors is relatively large, resulting in a low integration level of wall-mounted antennas.

[0052] Furthermore, when the PCB is mounted onto the metal substrate, the internal circuitry of the PCB may be damaged due to stress.

[0053] Based on this, this application provides a wall-mounted antenna and a method for manufacturing the wall-mounted antenna, wherein the wall-mounted antenna is lightweight and has a high degree of integration.

[0054] Figure 1 This is a schematic diagram of the structure of the wall-mounted antenna provided in an embodiment of this application; Figure 2 This is a schematic diagram of the internal structure of the wall-mounted antenna provided in an embodiment of this application; Figure 3 This is a schematic diagram of the structure of the base plate of the wall-mounted antenna provided in the embodiments of this application; Figure 4 This is another structural schematic diagram of the base plate of the wall-mounted antenna provided in an embodiment of this application.

[0055] See Figures 1 to 4 As shown, the wall-mounted antenna 100 provided in this application includes a base plate 110 and a vibrator 120. The base plate 110 is formed by injection molding of an organometallic composite material. The base plate 110 includes a non-metallic substrate 111, a front metal layer 112, and a back metal layer 113. The front metal layer 112 and the back metal layer 113 are formed on two opposite surfaces of the non-metallic substrate 111 by metallization. A portion of the front metal layer 112 is used to form a feed network 1121. The vibrator 120 includes a first vibrator 121. The first vibrator 121 includes a support portion 1211 and a vibrator base 1212 electrically connected to the support portion 1211. The base plate 110 has a through hole 114. The support portion 1211 passes through the through hole 114 so that both the front metal layer 112 and the back metal layer 113 are electrically connected to the support portion 1211.

[0056] Please continue reading Figure 1 As shown, the wall-mounted antenna 100 also includes an antenna cover 130, which includes an upper cover 131 and a support plate 132. The upper cover 131 and the support plate 132 together cover the base plate 110 and the components on the base plate 110, thereby protecting the components in the wall-mounted antenna 100. Figure 2 In order to clearly show the internal structure of the wall-mounted antenna 100, the top cover 131 of the antenna cover 130 is omitted.

[0057] The base plate 110 is processed using LDS (Laser Direct Structuring) technology. Specifically, the base plate 110 is injection molded using a metal-organic composite material. The metal-organic composite material includes insulating materials and metal ions. After injection molding, the metal ions are uniformly dispersed in the insulating matrix. In this embodiment, the metal ions can be Cu ions. The injection-molded base plate 110 has precise dimensions, and injection molding can produce base plates 110 of various shapes.

[0058] Laser irradiation causes metal ions to be deposited and distributed on the two opposing surfaces of the base plate 110, forming a sandwich structure with a non-metallic substrate 111 in the middle and metal layers on both sides of the non-metallic substrate 111. Copper plating is then performed on the surfaces of the two metal layers to form a front metal layer 112 and a back metal layer 113.

[0059] A portion of the front metal layer 112 forms the feed network 1121 of the wall-mounted antenna 100. Tin plating can also be applied to the feed network 1121 portion to protect it and facilitate soldering it to other components.

[0060] By using an organometallic composite material injection molding base plate 110, the weight of the wall-mounted antenna 100 can be reduced compared to metal base plates in related technologies.

[0061] The feed network 1121 is formed by the front metal layer 112 and is directly formed on the surface of the non-metallic substrate 111. Compared with the related technology, which uses multiple PCBs mounted on a metal substrate and requires multiple PCBs to be soldered together with coaxial cables to form the feed network, the feed network 1121 of this application integrates multiple PCBs and multiple coaxial cables, reducing the number of solder joints in the wall-mounted antenna 100. This simplifies the assembly process of the wall-mounted antenna 100 and reduces signal transmission loss, resulting in a higher integration of the wall-mounted antenna 100.

[0062] The back metal layer 113 serves as the reflective boundary of the wall-mounted antenna 100 and can also function as the grounding layer for the wall-mounted antenna 100. Since the back metal layer 113 is used only for the reflective boundary and grounding layer, its thickness is less than 0.3 mm. Controlling the thickness of the back metal layer 113 can further reduce the weight of the base plate 110.

[0063] The vibrator 120 needs to be electrically connected to the power supply network 1121, and the vibrator 120 also needs to be grounded. The vibrator 120 includes a first vibrator 121. Taking the first vibrator 121 as an example, the specific methods of the electrical connection between the vibrator 120 and the power supply network 1121 and the grounding of the vibrator 120 are explained.

[0064] Please continue reading Figure 2 and Figure 3 As shown, a through hole 114 is provided on the base plate 110. The through hole 114 is formed during injection molding. The support part 1211 of the first oscillator 121 passes through the through hole 114 and engages with the through hole 114, thereby mounting the first oscillator 121 on the base plate 110. Figure 2 and Figure 3 In the middle, the through hole 114 is a cross hole, and the cross section of the support part 1211 is also cross-shaped, thereby preventing the first oscillator 121 from rotating in the through hole 114.

[0065] The portion of the support 1211 located on the front metal layer 112 can be electrically connected to the front metal layer 112 by soldering, thereby electrically connecting the first oscillator 121 to the power supply network 1121; the portion of the support 1211 located on the back metal layer 113 can be electrically connected to the back metal layer 113 by soldering, thereby grounding the first oscillator 121. Thus, while mounting the first oscillator 121 on the base plate 110, the connection between the first oscillator 121 and the power supply network 1121 and the grounding of the first oscillator 121 are completed simultaneously. Compared to related technologies where the oscillator is electrically connected to the PCB board via a coaxial cable and grounded via the same cable, the oscillator 120 in this application eliminates the need for a coaxial cable and reduces the number of solder joints required for electrical connection, resulting in a higher integration between the oscillator 120 and the base plate 110.

[0066] Please continue reading Figures 2 to 4 As shown, the wall-mounted antenna 100 also includes a side plate 140, which surrounds the periphery of the base plate 110. Figures 2 to 4 In the illustrated embodiment, side plates 140 are only present on the two opposite sides of the base plate 110. It is understood that the side plates 140 are integrally formed with the base plate 110, and the two opposite surfaces of the side plates 140 also have metal layers.

[0067] The wall-mounted antenna 100 provided in this application, by setting a base plate 110 and an element 120, wherein the base plate 110 is formed by injection molding of an organometallic composite material, is lighter in weight than the metal substrate in related technologies, thus making the wall-mounted antenna 100 lighter. The base plate 110 includes a non-metallic substrate 111, a front metal layer 112, and a back metal layer 113. The front metal layer 112 and the back metal layer 113 are formed on two opposite surfaces of the non-metallic substrate 111 by metallization. Part of the front metal layer 112 is used to form a feed network 1121. The feed network 1121 integrates multiple PCB boards and multiple coaxial cables in related technologies, while reducing the number of solder joints in the wall-mounted antenna 100, thus making the wall-mounted antenna 100 more integrated. The vibrator 120 includes a first vibrator 121. A through-hole 114 is provided in the base plate 110. A support portion 1211 of the first vibrator 121 passes through the through-hole 114, so that both the front metal layer 112 and the back metal layer 113 are electrically connected to the support portion 1211. Thus, while mounting the first vibrator 121 on the base plate 110, the connection between the first vibrator 121 and the feed network 1121 and the grounding of the first vibrator 121 are completed. This eliminates the need for coaxial cables and reduces the number of solder joints required for electrical connections, resulting in a high degree of integration between the vibrator 120 and the base plate 110. The wall-mounted antenna 100 provided in this application is lightweight and has a high degree of integration.

[0068] The front metal layer 112 and the back metal layer 113 can also be electrically connected in other ways to facilitate the grounding of the oscillator 120.

[0069] Please continue reading Figure 3 and Figure 4 As shown, the base plate 110 has a metallized via 115, which is used to electrically connect the front metal layer 112 and the back metal layer 113.

[0070] Specifically, vias are formed on the base plate 110 during injection molding. Then, while performing copper plating on the surfaces of the two metal layers on both sides of the non-metallic substrate 111, copper plating is also performed on the surface of the vias to form metallized vias 115. The metallized vias 115 are used for electrical connection between the front metal layer 112 and the back metal layer 113. Thus, the front metal layer 112 and the back metal layer 113 can be electrically connected without adding any process steps to the wall-mounted antenna 100. Therefore, the vibrator 120 only needs to be electrically connected to the front metal layer 112.

[0071] Please continue reading Figure 2 As shown, the vibrator 120 also includes a second vibrator 122, and the wall-mounted antenna 100 also includes a vibrator feed 150. One end of the vibrator feed 150 is electrically connected to the front metal layer 112, and the other end of the vibrator feed 150 is electrically connected to the second vibrator 122.

[0072] The oscillator feed 150 can be a copper pillar, and the size of the oscillator feed 150 can be selected according to the different specifications of the second oscillator 122, thus making the oscillator feed 150 and the second oscillator 122 highly compatible.

[0073] It should be noted that in some embodiments, the wall-mounted antenna 100 includes only the first element 121, and in some embodiments, the wall-mounted antenna 100 includes only the second element 122. Figure 2 In the embodiment shown, the wall-mounted antenna 100 includes a first element 121 and a second element 122.

[0074] Depending on the usage environment of the wall-mounted antenna 100, some second elements 122 may be quite large, making it difficult to support them using the element feed 150. Therefore, a separate support column 116 is needed to support the second element 122.

[0075] Please continue reading Figure 2 As shown, a support column 116 is provided on the base plate 110. The support column 116 is integrally formed with the base plate 110 and is connected to the second vibrator 122.

[0076] Specifically, the support column 116 is integrally formed with the base plate 110 during injection molding. The specific position and number of the support columns 116 can be set according to the specific position and size of the second vibrator 122. Figure 2 In the embodiment shown, the second oscillator 122 is rectangular, and there are four support columns 116. The four apex corners of the support columns 116 are opposite to those of the second oscillator 122. The upper end of each support column 116 is connected to the second oscillator 122 through a connector, thereby mounting the second oscillator 122 on the base plate 110.

[0077] Please continue reading Figure 1 and Figure 2 As shown, the wall-mounted antenna 100 also includes a connector 160 and a connector cable 170. The base plate 110 has a connector support 117, which is integrally formed with the base plate 110. One end of the connector cable 170 is electrically connected to the feed network 1121, and the other end of the connector cable 170 is electrically connected to the connector 160. The connector cable 170 is snapped into the connector support 117.

[0078] Connector 160 is used to electrically connect the wall-mounted antenna 100 to other electronic devices. Connector 160 is electrically connected to the feed network 1121 via connector cable 170. Specifically, one end of connector cable 170 is plugged into connector 160, and the other end of connector cable 170 is soldered to feed network 1121.

[0079] A connector support 117 is also provided on the base plate 110, and the connector support 117 is integrally formed with the base plate 110 during injection molding. Please continue to the next section. Figure 2 and Figure 3 As shown, two connector supports 117 are provided on the base plate 110. The connector supports 117 have slots, and the connector cable 170 is snapped into the slots of the connector supports 117, thereby positioning the connector cable 170 and making the internal structure of the wall-mounted antenna 100 neat and beautiful.

[0080] Figure 5 A flowchart illustrating a method for manufacturing a wall-mounted antenna according to an embodiment of this application. See also... Figure 5 As shown, this application also provides a method for manufacturing a wall-mounted antenna, used to manufacture the wall-mounted antenna 100 provided in the above embodiments. The specific structure of the wall-mounted antenna 100 has been described in detail in the above embodiments and will not be repeated here.

[0081] The manufacturing methods for wall-mounted antennas include:

[0082] S101, The base plate 110 is formed by injection molding of organometallic composite material.

[0083] The base plate 110 is processed using LDS (Laser Direct Structuring) technology. Specifically, the base plate 110 is injection molded using a metal-organic composite material. The metal-organic composite material includes insulating materials and metal ions. After injection molding, the metal ions are uniformly dispersed in the insulating matrix. In this embodiment, the metal ions can be Cu ions. The injection-molded base plate 110 has precise dimensions, and injection molding can produce base plates 110 of various shapes.

[0084] S102. A front metal layer 112 and a back metal layer 113 are formed on the front and back sides of the base plate 110 by metallization, wherein a portion of the front metal layer 112 is used to form a power supply network 1121.

[0085] Laser irradiation causes metal ions to be deposited and distributed on the two opposing surfaces of the base plate 110, resulting in a base plate 110 with a non-metallic substrate 111 in the middle and metal layers on both sides of the non-metallic substrate 111. Copper plating is then performed on the surfaces of the two metal layers to form a front metal layer 112 and a back metal layer 113.

[0086] The back metal layer 113 serves as the reflection boundary of the wall-mounted antenna 100, and the back metal layer 113 can also be used as the grounding layer of the wall-mounted antenna 100.

[0087] S103. Connect the oscillator 120 to the front metal layer 112 and the back metal layer 113 electrically.

[0088] The oscillator 120 is electrically connected to the front metal layer 112, thereby being electrically connected to the power supply network 1121, and the oscillator 120 is electrically connected to the back metal layer 113 for grounding.

[0089] Electrically connecting the oscillator 120 to the front metal layer 112 and the back metal layer 113 includes: providing a through hole 114 on the base plate 110; passing the support portion 1211 of the first oscillator 121 through the through hole 114, and electrically connecting the support portion 1211 to the front metal layer 112 and the back metal layer 113.

[0090] The support portion 1211 of the first oscillator 121 passes through the through hole 114 and engages with the through hole 114, thereby mounting the first oscillator 121 on the base plate 110.

[0091] The portion of the support 1211 located on the front metal layer 112 can be electrically connected to the front metal layer 112 by welding, thereby electrically connecting the first oscillator 121 to the power supply network 1121; the portion of the support 1211 located on the back metal layer 113 can be electrically connected to the back metal layer 113 by welding, thereby grounding the first oscillator 121.

[0092] Electrically connecting the oscillator 120 to the front metal layer 112 and the back metal layer 113 includes: providing a metallized via 115 on the base plate 110 to electrically connect the front metal layer 112 and the back metal layer 113; and electrically connecting the second oscillator 122 to the front metal layer 112 through the oscillator feed 150.

[0093] One end of the oscillator feed 150 is electrically connected to the front metal layer 112, and the other end of the oscillator feed 150 is electrically connected to the second oscillator 122, thereby the second oscillator 122 is electrically connected to the front metal layer 112 through the oscillator feed 150. Since the front metal layer 112 and the back metal layer 113 are electrically connected through the metallized via 115, the second oscillator 122 is also electrically connected to the back metal layer 113.

[0094] The base plate 110 is formed by injection molding of an organometallic composite material, including integrally molding a support column 116 and a connector support 117 on the base plate 110. Both the support column 116 and the connector support 117 are integrally molded with the base plate 110, thereby simplifying the manufacturing steps of the wall-mounted antenna 100 and improving the integration of the wall-mounted antenna 100.

[0095] Finally, the antenna cover 130 is installed on the outside of the base plate 110 to complete the assembly of the wall-mounted antenna 100.

[0096] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them.
