The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.

The embodiment of the present application provides an antenna module 110, an antenna device 100 and an electronic device 10, where the antenna module 110 and the antenna device 100 can implement wireless communication functions, for example, wireless fidelity (Wireless Fidelity, wi-Fi) signals, global positioning system (Global Positioning System, GPS) signals, third Generation mobile communication technology (3 rd-Generation, 3G, 4th-Generation, 4G, 5th-Generation, 5G), near field communication (Near field communication, NFC) signals, ultra wideband communication (UWB) signals, and the like.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic diagram of a first structure of an antenna module 110 according to an embodiment of the present application, and fig. 2 is a schematic diagram of a first structure of an antenna device 100 according to an embodiment of the present application. The antenna device 100 of the embodiments of the present application includes one or more antenna modules 110. Each antenna module 110 may include a first radiating layer 111, a second radiating layer 112, and a plurality of conductive connections 113. The antenna device 100 may include a feed 120.

The second radiation layer 112 may be located at one side of the first radiation layer 111, and the second radiation layer 112 may be stacked and spaced apart from the first radiation layer 111. The first radiation layer 111 includes a plurality of first radiation units 1111, and the second radiation layer 112 includes a plurality of second radiation units 1121. Each of the conductive connection pieces 113 is located between the first radiation layer 111 and the second radiation layer 112, one end of each of the conductive connection pieces 113 is directly or indirectly electrically connected to the first radiation unit 1111, and the other end of each of the conductive connection pieces 113 is directly or indirectly electrically connected to the second radiation unit 1121. The plurality of second radiating elements 1121, the plurality of conductive connectors 113, and the plurality of first radiating elements 1111 may form a continuous current path S (a conductive path formed by a plurality of conductors that can flow electricity). The current paths S formed by the plurality of second radiating elements 1121, the plurality of conductive connectors 113, and the plurality of first radiating elements 1111 may collectively support transmission of wireless signals under the influence of the excitation signal provided by the feed 120 of the antenna apparatus 100.

Among them, each of the first radiating units 1111 and each of the second radiating units 1121 may be a structure formed of a conductor structure that may radiate electromagnetic wave signals. For example, but not limited to, the first radiating element 1111, the second radiating element 1121 may be a radiator formed of metal traces.

The first radiation layer 111 may be parallel to the second radiation layer 112, and the second radiation layer 112 may be disposed without contacting the first radiation layer 111. The first radiation layer 111 may be a carrier layer structure capable of carrying a plurality of first radiation units 1111, where the plurality of first radiation units 1111 may be formed on the first radiation layer 111 by, but not limited to, attaching, etching, bonding, etc. Of course, the first radiation layer 111 may not include the carrier layered structure but include only the plurality of first radiation units 1111, and in this case, the plurality of first radiation units 1111 may be in the same plane and form the first radiation layer 111 together. For the same reason, the second radiation layer 112 may also be a carrier layered structure capable of carrying a plurality of second radiation units 1121, or the plurality of second radiation units 1121 may be in the same plane and jointly form the second radiation layer 112. The specific structures of the first radiation layer 111 and the second radiation layer 112 are not limited in the embodiments of the present application.

As shown in fig. 1, a plurality of first radiating elements 1111 may be disposed at intervals on the first radiating layer 111, any adjacent two of the first radiating elements 1111 may not be connected, and the plurality of first radiating elements 1111 may be arranged in an array on the first radiating layer 111. Similarly, the plurality of second radiation units 1121 may be disposed at intervals on the second radiation layer 112, any two adjacent second radiation units 1121 may not be connected, and the plurality of second radiation units 1121 may be arranged in an array on the second radiation layer 112. Needless to say, the plurality of first radiating elements 1111 may be arranged at any interval without being arranged in an array, and the plurality of second radiating elements 1121 may be arranged at any interval without being arranged in an array, which is not limited in comparison with the present embodiment.

It will be appreciated that, as shown in fig. 1, one end of each conductive connection member 113 may be electrically connected to the tail end of the previous first radiating element 1111, and the other end of each conductive connection member 113 may be electrically connected to the head end of the next second radiating element 1121. The projection of each of the second radiating elements 1121 on the first radiating layer 111 may intersect at least one of the first radiating elements 1111, the projection of each of the first radiating elements 1111 on the second radiating layer 112 may intersect at least one of the second radiating elements 1121, and thus, the plurality of first radiating elements 1111, the plurality of conductive connectors 113 and the plurality of second radiating elements 1121 may be circularly arranged in the order of one of the first radiating elements 1111, one of the conductive connectors 113, one of the second radiating elements 1121, the other of the conductive connectors 113, the other of the first radiating elements 1111, the other of the conductive connectors 113 and the other of the second radiating elements 1121 … …, and the plurality of first radiating elements 1111 and the plurality of second radiating elements 1121 may form a continuous current path S sequentially connected under the effect of the plurality of conductive connectors 113, it may be understood that the current path S may be a current path S of a spiral structure.

The plurality of first radiating elements 1111 and the plurality of second radiating elements 1121 in the embodiment of the present application may not be disposed on the first radiating layer 111 and the second radiating layer 112 in the above manner. Referring to fig. 3 and fig. 4, fig. 3 is a schematic diagram of a second structure of the antenna module 110 according to the embodiment of the present application, and fig. 4 is a schematic diagram of a second structure of the antenna device 100 according to the embodiment of the present application. The two or more first radiating elements 1111 of the embodiment of the present application may be connected to each other on the first radiating layer 111 instead of being spaced apart, and the two or more second radiating elements 1121 may be connected to each other on the second radiating layer 112 instead of being spaced apart. For example, in fig. 3 and 4, two first radiating elements 1111a and 1111b may be connected to each other and formed integrally, and two second radiating elements 1121a and 1121b may be connected to each other and formed integrally. At this time, one end of one conductive connection member 113 may be electrically connected to the first radiating elements 1111a and 1111b formed integrally, and the other end of the conductive connection member 113 may be electrically connected to the second radiating elements 1121a and 1121b formed integrally. At this time, the plurality of first radiating elements 1111 and the plurality of second radiating elements 1121 may also form a continuous current path S by the plurality of conductive connectors 113.

It will be appreciated that in practice, the conductive connection 113 may extend through some medium (such as the substrate 130 hereinafter) during the process of connecting the first radiating element 1111 and the second radiating element 1121, but limited by the internal components of the electronic device 10, there may be some areas where it is not suitable to provide the conductive connection 113. At this time, the antenna module 110 may adjust the positions of the plurality of first radiating elements 1111 and the plurality of second radiating elements 1121 such that a portion of the first radiating elements 1111 may be connected to each other and a portion of the second radiating elements 1121 may be connected to each other, so that the conductive connector 113 may avoid an improper installation space.

It should be noted that the above is merely an example of forming the continuous current path S by the plurality of first radiating elements 1111, the plurality of conductive connectors 113, and the plurality of second radiating elements 1121, and other ways of forming the continuous current path S are within the scope of the embodiments of the present application, which are not limited thereto.

It will be appreciated that in the embodiment shown in fig. 1 and 2, two conductive connectors 113 are often required to implement one first radiating element 1111 and two second radiating elements 1121 (the first radiating element and the last radiating element may not be considered), and when the number of the first radiating element 1111 and the second radiating element 1121 are both N, the number of the conductive connectors 113 may be at least (2N-2). In the embodiment shown in fig. 3 and 4, the number of the conductive connection pieces 113 in the embodiment shown in fig. 2 may be less than (2N-2) because a part of the first radiating element 1111 is connected to the adjacent first radiating element 1111 and a part of the second radiating element 1121 is connected to the adjacent second radiating element 1121. It should be noted that the number of the conductive connection members 113 may be adjusted according to practical situations, which is not limited in the embodiment of the present application.

It is understood that when the plurality of first radiating elements 1111, the plurality of second radiating elements 1121 and the plurality of conductive connecting members 113 are connected to each other, as shown in fig. 1 and 2, the continuous current path S formed by the plurality of first radiating elements 1111, the plurality of second radiating elements 1121 and the plurality of conductive connecting members 113 may be a spiral structure like a spring. Of course, by arranging the shapes and positions of the plurality of first radiating elements 1111, the plurality of second radiating elements 1121 and the plurality of conductive connectors 113, the continuous current path S formed by the plurality of first radiating elements 1111, the plurality of second radiating elements 1121 and the plurality of conductive connectors 113 may also form a spiral structure of other structures, such as, but not limited to, an archimedes spiral structure, a racehorse spiral structure, an isopod spiral structure, a hyperbolic spiral structure, an in-circle spiral structure, an interlocking spiral structure, etc. The specific form of the spiral structure formed by the antenna device 100 is not limited in the embodiments of the present application. It should be noted that, by setting the shapes and positions of the plurality of first radiating elements 1111, the plurality of second radiating elements 1121, and the plurality of conductive connectors 113, the continuous current path S formed by the plurality of first radiating elements 1111, the plurality of second radiating elements 1121, and the plurality of conductive connectors 113 may be formed in other shapes such as curves and folding lines, and the specific shape of the current path S is not limited in the embodiment of the present application, and any shape that can form the continuous current path S is within the scope of protection of the embodiment of the present application.

It is to be understood that the first radiating element 1111 and the second radiating element 1121 may have a strip-shaped structure as shown in fig. 1, and the first radiating element 1111 and the second radiating element 1121 may have an arc-shaped curve structure as shown in fig. 3. The structure of each first radiating element 1111 may be identical, and of course, the structure of one or more (two or more) first radiating elements 1111 may be different; similarly, the structure of each second radiating element 1121 may be identical, and the structure of one or more (two or more) second radiating elements 1121 may be different. The embodiment of the present application is not limited to the specific shape and specific structure of the first radiating element 1111 and the second radiating element 1121.

In the antenna module 110 and the antenna device 100 according to the embodiments of the present application, when the plurality of first radiating elements 1111, the plurality of second radiating elements 1121, and the plurality of conductive connectors 113 are connected to each other to form a continuous current path S, the current path S according to the embodiments of the present application may be a three-dimensional structure rather than a planar structure, and the three-dimensional current path S may extend and expand in a three-dimensional space due to the stacked arrangement of the first radiating layers 111 and the second radiating layers 112. On the one hand, the antenna module 110 and the antenna device 100 having the continuous current path S may realize circular polarization performance, and the antenna device 100 may have higher gain and more flexible beam scanning characteristics; on the other hand, compared with the planar structure with the same electrical length, the three-dimensional current path S of the present application can not only ensure the electrical length requirement, but also occupy a smaller space on a plane (for example, the projection area of the three-dimensional current path S of the present application on the horizontal plane can be smaller than the projection of the planar structure with the same perimeter on the horizontal plane), and the antenna module 110 and the antenna device 100 can realize a miniaturized design; on the other hand, the first radiation layer 111 provided with the first radiation unit 1111 and the second radiation layer 112 provided with the second radiation unit 1121 may be modularized, and may be flexibly disposed in a limited space of the antenna device 100, the electronic device 10, etc. according to the installation requirements of the antenna module 110 and the antenna device 100, the assembly of the antenna module 110 is more flexible; in still another aspect, the first radiation layer 111 is provided with a plurality of first radiation units 1111, and the second radiation layer 112 is provided with a plurality of second radiation units 1121, and the plurality of first radiation units 1111 and the plurality of second radiation units 1121 may be flexibly arranged on the first radiation layer 111 and the second radiation layer 112 according to the actual application situation of the antenna device 100, so that the setting positions of the first radiation units 1111 and the second radiation units 1121 are more flexible, and the assembly of the antenna module 110 and the antenna device 100 is more facilitated.

Referring to fig. 1 and fig. 2 in combination with fig. 5 and fig. 6, fig. 5 is a schematic diagram of a third structure of an antenna module 110 according to an embodiment of the present application, and fig. 6 is a schematic diagram of a third structure of an antenna device 100 according to an embodiment of the present application. The antenna module 110 according to the embodiment of the present application may further include one or more (two or more) conductive members 116 at the end of the current path S.

The current path S may include two end portions, which may be entirely formed on the first radiation layer 111 or the second radiation layer 112, or one of the two end portions may be formed on the first radiation layer 111 and the other end portion may be formed on the second radiation layer 112. When the antenna module 110 includes a conductive member 116, the conductive member 116 may be connected to one end; when the antenna module includes two plurality of conductive elements 116, at least one conductive element 116 may be connected to one end and at least another conductive element connected to the other end.

As illustrated in fig. 5 and 6, one end of a certain first radiating element 1111, e.g., a first radiating element 1111c, of the first radiating layer 111 may be electrically connected to the second radiating element 1121 through one conductive connection 113, the other end of the first radiating element 1111c may not be electrically connected to the second radiating element 1121 through the conductive connection 113, and the other end of the first radiating element 1111c may be a first free end; another first radiating element 1111 of the first radiating layer 111, for example, one end of a first radiating element 111d is electrically connected to the second radiating element 1121 through the conductive connection 113, the other end of the first radiating element 1111d may not be electrically connected to the second radiating element 1121 through the conductive connection 113, and the other end of the first radiating element 1111d may be a second free end; at this time, at least one conductive member 116 may be connected to the first free end and electrically connected to the current path S, and at least another conductive member 116 may be connected to the second free end and electrically connected to the current path S.

It will be appreciated that the conductive element 116 may extend the length of the current path S to optimize the radiation performance of the antenna module 110. It will be appreciated that, as shown in fig. 5 and 6, the antenna module 110 may also be electrically connected to the feed 120 through a conductive member 116 so that the feed 120 may feed an excitation signal to the antenna module 110.

Note that, the feed source 120 may be electrically connected to the current path S through the conductive element 116, and the feed source 120 may also be electrically connected to the current path S through other manners, which is not limited in the embodiment of the present application.

It is understood that when a plurality of conductive members 116 are connected to the same end of the current path S, the plurality of conductive members 116 may be connected in series to each other to further extend the length of the current path S.

It is understood that the conductive element 116 may have a structure with conductive properties, and the conductive element 116 may have the same structure as the conductive connection element 113, for example, the conductive element 116 and the conductive connection element 113 may be metal vias; of course, the conductive element 116 may also have a different structure from the conductive connection element 113, for example, the conductive element 116 may be a metal wire, and the conductive connection element 113 may be a metal via. Note that, the specific structures of the conductive member 116 and the conductive connecting member 113 in the embodiment of the present application are not limited to the above description, and the specific structures of the conductive member 116 and the conductive connecting member 113 in the embodiment of the present application are not limited.

Referring again to fig. 5 and 6, the antenna device 100 or the antenna module 110 of the embodiment of the present application may further include a feeder layer 114.

One end of the feeder layer 114 may be directly or indirectly electrically connected to the first radiating element 1111 or the second radiating element 1121, for example, but not limited to, one end of the feeder layer 114 may be electrically connected to the conductive member 116; the other end of the feeder layer 114 may be directly or indirectly electrically connected to the feed source 120, the feed source 120 may provide an excitation signal, and the feeder layer 114 may transmit the excitation signal provided by the feed source 120 to the electrically connected first radiating element 1111 or second radiating element 1121 (or current path S) to excite a stereoscopic current path S formed by the plurality of second radiating elements 1121, the plurality of conductive connectors 113 and the plurality of first radiating elements 1111 to form resonance and support transmission of wireless signals.

It will be appreciated that when the antenna apparatus 100 includes a plurality of antenna modules 110, the plurality of antenna modules 110 may be electrically connected to the same feed source 120 through respective feeder layers 114, the feed source 120 may provide excitation signals to the plurality of antenna modules 110 by, but not limited to, a power divider or a power distribution circuit, and the plurality of antenna modules 110 may support transmission of the same wireless signal. Of course, the antenna device 100 may also include two or more feeds 120, where two or more antenna modules 110 may be electrically connected to different feeds 120, where each antenna module 110 may form respective resonances and support respective wireless signal transmission under the excitation of the respective electrically connected feeds 120, and the multiple antenna modules 110 may support the same wireless signal, or at least two antenna modules 110 may support different wireless signals.

It is to be appreciated that the feeder layer 114 can include, but is not limited to, one or more combinations of microstrip lines, striplines, coplanar waveguides, and that the feeder layer 114 can be formed, but is not limited to, by spraying, etching, and the like.

It is understood that the feeder layer 114 may be disposed coplanar with the first radiation layer 111 or the second radiation layer 112. For example, when the first radiation layer 111 or the second radiation layer 112 is formed on a certain surface of a certain medium, the feeder layer 114 may also be formed on the surface of the medium, and in this case, the medium may be fully utilized as a carrier, and the whole antenna apparatus 100 may be integrated on the same medium, so as to facilitate the antenna apparatus 100 being disposed inside the electronic device 10. Of course, the feeder layer 114 may be stacked on the first radiation layer 111 and the second radiation layer 112, and the feeder layer 114 may not be coplanar with the first radiation layer 111 and the second radiation layer 112. The specific structure of the feeder layer 114 is not limited in the embodiment of the present application.

Referring to fig. 1 to 6 and fig. 7, fig. 7 is a schematic diagram of a first connection of the antenna module 110 shown in fig. 5. The antenna module 110 of the embodiments of the present application may be carried on the substrate 130.

It is understood that the substrate 130 may be a component of the antenna device 100, the electronic apparatus 10, and the antenna device 100, the electronic apparatus 10 may include the substrate 130. Alternatively, the substrate 130 may be a component of the antenna module 110 itself, and other components of the antenna module 110 may be carried on the substrate 130. Alternatively, the substrate 130 may be a component of another device. The substrate 130 may be, but is not limited to, a circuit board, a bracket, a back cover, a small board, or the like.

The hole wall of the metal via hole is sprayed with a conductive material, one end of the metal via hole can be electrically connected with one first radiating element 1111, and the other end of the metal via hole can be electrically connected with one second radiating element 1121, so that a plurality of second radiating elements 1121, a plurality of metal via holes and a plurality of first radiating elements 1111 can form a three-dimensional continuous current path S.

It is understood that the feeder layer 114 of each antenna module 110 may be formed on the first surface 131 or the second surface 132 of the substrate 130, as with the first radiation layer 111 and the second radiation layer 112. Of course, the feeder layer 114 may be disposed in other areas, for example, but not limited to, an inner space (a space between the first surface 131 and the second surface 132) of the substrate 130, in which the substrate 130 is often formed by laminating a plurality of plate structures in actual products, and the feeder layer 114 may be disposed in a certain layer of the substrate 130 during the preparation process of the substrate 130, which is not limited to a specific forming manner of the feeder layer 114 in this embodiment.

According to the antenna module 110 and the antenna device 100 of the embodiment, the first radiation layer 111 is formed on the first surface 131 of the substrate 130, the second radiation layer 112 is formed on the second surface 132 of the substrate 130, the antenna module 110 can fully utilize the surface space of the substrate 130 for layout, and the antenna module 110 is integrated on the substrate 130 without occupying extra space, which is beneficial for the antenna module 110 to be built in the antenna device 100 or the electronic device 10, and can also realize the miniaturization design of the antenna module 110 and the antenna device 100.

Referring to fig. 1 to 6 and fig. 8, fig. 8 is a schematic diagram of a second connection of the antenna module 110 shown in fig. 5. The first radiation layer 111 or the second radiation layer 112 of the antenna module 110 may be produced modularly.

At this time, a plurality of first radiating elements 1111 of the first radiating layer 111 may be formed on the third face 1112 of the first radiating layer 111; the second radiation layer 112 and the plurality of second radiation cells 1121 on the second radiation layer 112 may be formed on the second face 132 of the substrate 130; each of the conductive connection members 113 may penetrate the first radiation layer 111 and the substrate 130, and each of the conductive connection members 113 may penetrate the third surface 1112 to the second surface 132 such that one end of the conductive connection member 113 may be electrically connected with the first radiation unit 1111 of the third surface 1112 and the other end may be electrically connected with the second radiation unit 1121 of the second surface 132.

It will be appreciated that, in practical use, the conductive connection 113 may include a plurality of sub-components and extend through the first radiation layer 111 and the substrate 130, respectively, considering that the conductive connection 113 extends through both the first radiation layer 111 and the substrate 130 in the process of extending through the third surface 1112 to the second surface 132. For example, when the conductive connection member 113 is a metal via hole, a first metal via hole 1131 may be disposed in the first radiation layer 111, a second metal via hole 1132 may be disposed in the substrate 130, two metal via holes may be disposed opposite to each other, and a connection structure 1133 such as a pad may be disposed at a connection location between the two metal via holes, so that the two metal via holes may be better electrically connected. It should be noted that the above is only an exemplary illustration that the conductive connecting member 113 penetrates the third surface 1112 to the second surface 132, and other solutions that can achieve the above purpose are all within the scope of the embodiments of the present application.

Referring to fig. 9, fig. 9 is a schematic diagram illustrating a third connection of the antenna module 110 shown in fig. 5. When the plurality of first radiating elements 1111 of the first radiating layer 111 are formed on the third face 1112 of the first radiating layer 111, the second radiating layer 112 and the plurality of second radiating elements 1121 on the second radiating layer 112 may also be formed in the region of the substrate 130 between the first face 131 and the second face 132 of the substrate 130, and the plurality of second radiating elements 1121 may be located inside the substrate 130. At this time, each of the conductive connection members 113 may penetrate the first radiation layer 111 and a portion of the substrate 130, one end of the first conductive connection member 113 may be electrically connected to the first radiation unit 1111 of the third surface 1112, and the other end may be electrically connected to the second radiation unit 1121 located between the first surface 131 and the second surface 132.

The detailed description may refer to the foregoing embodiments, and will not be repeated herein.

According to the antenna module 110 and the antenna device 100, the first radiation layer 111 is of a plate-shaped structure with a certain thickness, processes such as etching or spraying are not needed on the surface of the substrate 130, the first radiation layer 111 can be produced and processed independently of the substrate 130, modularized production can be achieved for the first radiation layer 111, and production of the first radiation layer 111 is simpler and more efficient. In addition, the modularized first radiation layer 111 has a certain thickness, so that the conductive connection piece 113 in the embodiment of fig. 8 and fig. 9 has a longer length compared with the conductive connection piece 113 in the embodiment of fig. 7, and the antenna module 110 forms a stereoscopic current path S with a longer electrical length, which is convenient for the antenna module 110 to radiate low-frequency signals and can also improve the circular polarization performance of the antenna module 110. Also, when the second radiation layer 112 is formed between the first face 131 and the second face 132 of the substrate 130, the second radiation layer 112 is farther from the circuit devices provided on the second face 132 of the substrate 130, and the second radiation layer 112 is less affected by the circuit devices on the second face 132.

Referring to fig. 1 to 6 and fig. 10, fig. 10 is a fourth connection schematic diagram of the antenna module 110 shown in fig. 5. The antenna device 100 of the embodiment of the present application may further dispose the antenna modules 110 on both side portions of the substrate 130.

A plurality of first radiating elements 1111 may be formed at the third surface 1112 of the first radiating layer 111, a plurality of second radiating elements 1121 may be formed at the sixth surface 1123 of the second radiating layer 112, and each of the conductive connectors 113 may penetrate through the third surface 1112 to the sixth surface 1123 such that one end of the conductive connector 113 may be electrically connected with the first radiating element 1111 of the third surface 1112 and the other end may be electrically connected with the second radiating element 1121 of the sixth surface 1123.

It is understood that the plurality of first radiating elements 1111 may be metal traces formed on the third surface 1112 of the first radiating layer 111, and the metal traces may not be provided on the fourth surface 1113 of the first radiating layer 111 without forming the first radiating elements 1111; the plurality of second radiating elements 1121 may be metal traces formed on the sixth face 1123 of the second radiating layer 112, and the metal traces may not be disposed on the fifth face 1122 of the second radiating layer 112 without forming the second radiating elements 1121.

It is understood that the conductive connection 113 may include a first metal via 1131 formed inside the first radiation layer 111, a second metal via 1132 formed inside the substrate 130, and a third metal via 1134 formed inside the second radiation layer 112, which may be connected by, but not limited to, a pad. The detailed description may refer to the foregoing embodiments, and will not be repeated herein.

According to the antenna device 100, the first radiation layer 111 and the second radiation layer 112 are of plate-shaped structures with certain thickness, modularized production can be achieved for the first radiation layer 111 and the second radiation layer 112, and production of the first radiation layer 111 and the second radiation layer 112 is simpler and more efficient. In addition, the modularized first radiation layer 111 and the modularized second radiation layer 112 have a certain thickness, so that the electrical length of the three-dimensional current path S formed by the antenna device 100 is longer, which is more beneficial to the antenna device 100 to radiate low-frequency signals and is also more beneficial to improving the circular polarization performance of the antenna device 100.

It should be noted that the above is merely an exemplary connection manner between the antenna module 110 and the substrate 130 in the embodiment of the present application, and is not limited thereto, for example, the first radiation layer 111 and the second radiation layer 112 may be further separated by a plurality of substrates 130. The specific connection manner between the antenna device 100 and the substrate 130 is not limited in the embodiment of the present application.

It should be noted that, in addition to being carried on the substrate 130, the antenna module 110 of the embodiment of the present application may also be separately and modularly arranged, that is, the antenna module 110 may be a plate-shaped structure with a certain thickness, the first radiation layer 111 and the second radiation layer 112 may be respectively located at two sides of the plate-shaped structure, and the conductive connection member 113 may penetrate through the plate-shaped structure. The antenna device 100 may be independently mounted inside the electronic apparatus 10 without attaching to the substrate 130.

Based on the antenna module 110 of the above embodiment, referring again to fig. 7, each antenna module 110 of the embodiments of the present application may further include a ground plane layer 115.

The ground plane layer 115 may have a ground area 1151 formed thereon, a projection of the ground area 1151 onto the first radiation layer 111 being located outside the plurality of first radiation units 1111, and a projection of the ground area 1151 onto the second radiation layer 112 being located outside the plurality of second radiation units 1121. The area of the ground plane layer 115 other than the ground area 1151 may be a headroom area 1152, and the projection of the headroom area 1152 onto the first radiation layer 111 may cover the plurality of first radiation elements 1111 and the projection onto the second radiation layer 112 may cover the plurality of second radiation elements 1121.

At this time, the grounding area 1151 does not affect the radiation of the signals of the first and second radiation units 1111 and 1121, and the grounding area 1151 may also serve as a reflection plate to reflect the electromagnetic waves radiated from the first and second radiation units 1111 and 1121, so that the electromagnetic waves may radiate in a desired direction, and the antenna apparatus 100 may have a better directional radiation performance.

Of course, the first radiating element 1111 and the second radiating element 1121 may be directly or indirectly electrically connected to the ground area 1151, and in this case, the ground area 1151 may make the impedance of the first radiating element 1111 and the second radiating element 1121 smaller, so as to ensure the radiation performance of the antenna apparatus 100.

It is understood that the ground plane layer 115 in the embodiments of the present application may be a one-layer structure or a multi-layer structure. When the ground plane layers 115 are of a multi-layer structure, the multi-layer ground plane layers 115 may be spaced apart from each other, and the antenna module 110 may further include ground connectors (not shown) that may electrically connect the ground areas 1151 of the multi-layer ground plane layers 115 to each other as a unit, such as, but not limited to, one or more metal via structures (including structures such as pads, electrical connections, electrical connection points, etc. connecting a plurality of metal via structures). The areas of the ground areas 1151 of the multilayer ground plane layers 115 in the embodiment of the present application may be accumulated, on one hand, the space occupied by the multilayer ground plane layers 115 on a certain layer may be smaller, and on the other hand, the multilayer ground plane layers 115 may be flexibly disposed inside the antenna apparatus 100 or the electronic device 10, so that the multilayer ground plane layers 115 are beneficial to the antenna apparatus 100 or the electronic device 10 to realize a miniaturized design.

In order to further improve the directivity of the antenna device 100, the shape of the ground area 1151 may be designed. For example, please refer to fig. 11, fig. 11 is a fifth connection schematic diagram of the antenna module 110 shown in fig. 5. The ground region 1151 may form a channel structure 1153.

The ground region 1151 may extend from an edge of the ground plane layer 115 toward the body of the ground plane layer 115, the region of the ground region 1151 corresponding to the first radiation layer 111 and the second radiation layer 112 may form a slot structure 1153, the slot structure 1153 may not be provided with a conductive material, the slot structure 1153 may form a headroom region 1152 in the foregoing embodiment, a projection of the slot structure 1153 on the first radiation layer 111 may cover the plurality of first radiation units 1111, a projection on the second radiation layer 112 may cover the plurality of second radiation units 1121, and an opening of the slot structure 1153 may face the antenna module 110 to support a main radiation direction when wireless signal transmission is supported. For example, in fig. 11, the main lobe direction of radiation during the transmission of the wireless signal in the three-dimensional spiral structure formed by the plurality of first radiating elements 1111, the plurality of second radiating elements 1121 and the plurality of conductive connectors 113 may be oriented toward the left area, and the opening of the slot structure 1153 of the grounding area 1151 may be oriented toward the left area.

It is appreciated that as shown in fig. 11, the opening diameter of the first end 1154 of the channel structure 1153 may be equal or approximately equal to the opening diameter of the second end 1155, and the channel structure 1153 may be a rectangular channel structure that is easier to form during the manufacturing process. Of course, the tank structure 1153 may be other structures, which will not be described in detail herein.

In the antenna module 110 of the present embodiment, the grounding area 1151 is provided with the groove structure 1153 with an opening facing the main radiation direction of the antenna device 100, and the grounding area 1151 can make the radiation beam of the antenna device 100 more concentrated in the main radiation direction, so as to improve the directivity of the antenna device 100.

Referring to fig. 12, fig. 12 is a schematic diagram illustrating a sixth connection of the antenna module 110 shown in fig. 5. The diameter of the channel structure 1153 of the grounding region 1151 of the present embodiment may taper linearly or non-linearly from a first end 1154 near the edge of the ground plane layer 115 to a second end 1155 away from the edge of the ground plane layer 115.

The slot structure 1153 may include a first end 1154 and a second end 1155, the first end 1154 may be an end proximate to the ground plane edge and the second end 1155 may be an end distal to the ground plane edge, the first end 1154 and the second end 1155 being open structures of a virtual body.

It will be appreciated that, as shown in fig. 12, the opening diameter of the first end 1154 may be larger than the opening diameter of the second end 1155, the slot structure 1153 may form a horn structure, and the slot structure 1153 of the horn structure may reflect more radiation energy of the first radiation unit 1111 and the second radiation unit 1121 to the main radiation direction of the antenna apparatus 100, so that the directivity of the antenna apparatus 100 is better.

It will be appreciated that the edge of the ground region 1151 at the channel structure 1153 may taper linearly as shown in fig. 12; of course, the edge of the grounding area 1151 at the slot structure 1153 may also be non-linearly tapered, for example, referring to fig. 13, fig. 13 is a seventh connection schematic diagram of the antenna module 110 shown in fig. 5, where the edge of the grounding area 1151 at the slot structure 1153 is gradually tapered, and the wavy slot edge may increase the number of reflections of the radiation energy at the slot structure 1153 to further improve the directivity of the antenna device 100.

It should be noted that the specific shape of the slot 1153 is not limited to the above example, and for example, the edge of the grounding area 1151 at the slot 1153 may be a dressing loading structure, a tooth structure, or the like. The specific structures of the tank structure 1153 and the grounding region 1151 are not limited in the embodiment of the present application.

In the antenna device 100 of the present embodiment, the groove structure 1153 of the grounding area 1151 is a horn-shaped structure, and the grounding area 1151 can further concentrate the radiation beam of the antenna device 100 in the main radiation direction, so as to improve the directivity of the antenna device 100.

The feed 120 may provide an excitation signal for each antenna module 110, multiple antenna modules 110 may support transmission of the same wireless signal, and multiple antenna modules 110 may form an antenna array.

It will be appreciated that the main radiation directions of the plurality of antenna modules 110 may be oriented in the same direction, so that the directivity of the antenna array is stronger.

It will be appreciated that when the antenna device 100 includes a plurality of antenna modules 110, each antenna module 110 may have a respective ground plane layer 115. Of course, the ground plane layers 115 of two or more antenna modules 110 may be connected to form the same ground plane layer 115, and in practical use, multiple antenna modules 110 may often share the same ground plane layer 115, and the antenna device 100 may include a larger ground plane layer 115. Illustratively, the ground plane layer 115 of the two or more antenna modules 110 may be a ground plane layer 115 of a two or more layer structure, and the two or more ground plane layers 115 may be electrically connected as a whole, but not limited to, by a ground connection such as a metal via.
