FIG. 1 is a schematic diagram of a three-dimensional antenna device according to an embodiment of the present invention. Please refer to FIG. 1, the three-dimensional antenna device 100 includes a first substrate 110, a second substrate 120 and a plurality of flexible conductive pillars 130. The first substrate 110 is provided with a wireless communication chip 111 and a first antenna 112 that are electrically connected to each other. The second substrate 120 is disposed opposite to the first substrate 110. The second substrate 120 is provided with a second antenna 121. The flexible conductor post 130 is connected between the first substrate 110 and the second substrate 120 and is electrically connected to the first antenna 112 and the second antenna 121.

The first substrate 110 and the second substrate 120 are, for example, a printed circuit board (Printed Circuit Board, PCB). In detail, the printed circuit board is, for example, a Rigid Printed Circuit Board (RPCB) made of FR-4 material, or a Polyimide (Flexible Printed Circuit, FPC) The flexible circuit board made. In addition, according to different signal transmission strength requirements, the first substrate 110 and the second substrate 120 can be a single sided board, a double sided board, or a multi layer board. The shape of the first substrate 110 and the second substrate 120 may be circular, but not limited to this. The first substrate 110 and the second substrate 120 can be provided for the first antenna 112, the second antenna 121, the wireless communication chip 111 and other electronic components (not shown). In detail, the first substrate 110 may have a first surface S1 and a second surface S2 opposite to each other. The first surface S1 faces the second substrate 120. The wireless communication chip 111 may be disposed on the first surface S1 or the second surface S2. For example, the wireless communication chip 111 of this embodiment may be provided on the first surface S1 facing the second substrate 120. In this way, the wireless communication chip 111 can be prevented from being worn by other components (for example, the housing 210 in FIG. 3). In another embodiment, the wireless communication chip 111 may also be provided on the second surface S2 facing away from the second substrate 120 to increase the space between the first substrate 110 and the second substrate 120.

In this embodiment, the first antenna 112 is, for example, a routing of the first substrate 110. Similarly, the second antenna 121 can also be a winding of the second substrate 120. The first antenna 112 depicted in FIG. 1 is, for example, arranged along the edge of the first substrate 110, and the second antenna 121 is similar to the first antenna 112 and is also arranged along the edge of the second substrate 120. However, in other embodiments, the shapes of the first antenna 112 and the second antenna 121 may be different from those shown in FIG. 1, and the shapes of the first antenna 112 and the second antenna 121 may also be different from each other. . In this embodiment, the specific structures of the first antenna 112 and the second antenna 121 are not much restricted.

The flexible conductor post 130 is made of a conductive material with flexibility. For example, the material of the flexible conductor post 130 may include copper, so that the flexible conductor post 130 can be bent and can also transmit signals stably. Since the flexible conductor post 130 is flexible, the angle of the first substrate 110 relative to the second substrate 120 can be changed by bending the flexible conductor post 130 to conform to the space where the three-dimensional antenna device 100 is arranged. Detailed features will be explained below. On the other hand, although the flexible conductive column 130 is flexible, the flexible conductive column 130 does not need to be bent in order to fit different-shaped carrier shells. For example, the axial direction of each flexible conductor post 130 in this embodiment extends along a predetermined direction D. The number of flexible conductive pillars 130 is, for example, at least one. Specifically, the number of flexible conductor posts 130 can be changed according to the configuration of the first antenna 112 and the second antenna 121. In this embodiment, the number of flexible conductive posts 130 is, for example, two, but it is not limited thereto.

FIG. 2 is a schematic diagram of a flexible conductor post of the three-dimensional antenna device of FIG. 1 being bent. Please refer to FIG. 2, the flexible conductive pillars 130a may each have a bent structure. In detail, after the flexible conductive pillar 130a is bent, the second substrate 120 can be inclined with respect to the first substrate 110. In this way, the angle between the first substrate 110 and the second substrate 120 can be changed, so that the spatial shape corresponding to the three-dimensional antenna device 100 a of FIG. 2 is different from that of the three-dimensional antenna device 100 of FIG. 1. It should be noted that the flexible conductor post 130a with a bent structure shown in FIG. 2 is only an example. In other embodiments, the bending amplitude of the flexible conductor post 130a may also be different from that shown in FIG. 2. This embodiment does not limit the bending extent of the flexible conductive column 130a.

Compared with the prior art, since the present embodiment adopts the three-dimensional antenna device 100 with the flexible conductor post 130, by bending the flexible conductor post 130, the distance between the first substrate 110 and the second substrate 120 can be changed. The relative angle further conforms to the spatial shape of the three-dimensional antenna device 100. Based on the above, the three-dimensional antenna device 100 of this embodiment can have the advantage of easy configuration.

Please refer to Figure 1 again. In addition to the flexible conductor post 130, if the size of the three-dimensional antenna device 100 is larger, an insulating post (not shown) can be disposed between the first substrate 110 and the second substrate 120. The insulating column can be supported between the first substrate 110 and the second substrate 120 to improve the structural strength of the three-dimensional antenna device 100. The insulating column can be bent synchronously with the flexible conductive column 130 to adjust the angle of the first substrate 110 relative to the second substrate 120.

FIG. 3 is a schematic diagram of a three-dimensional antenna device carrier according to an embodiment of the present invention. Please refer to FIG. 3, the three-dimensional antenna device carrier 200 includes the three-dimensional antenna device 100 and the housing 210 described above.

The material of the housing 210 may include plastic, but is not limited to this. The casing 210 can be assembled or integrally formed, and the shape of the casing 210 can be any shape. This embodiment does not limit the specific structure of the housing 210. In this embodiment, whether each flexible conductor post 130 of the three-dimensional antenna device 100 needs to be bent is determined according to the accommodating space 211 provided by the housing 210. For example, the accommodating space 211 of this embodiment can accommodate the three-dimensional antenna device 100 without the flexible conductor post 130 being bent. Therefore, the axial direction of each flexible conductor post 130 extends along the predetermined direction D.

In another embodiment, the three-dimensional antenna device carrier 200a shown in FIG. 4, the first substrate 110 and the second substrate 120 are adapted to follow the shape of the accommodating space 211a of the housing 210a and incline relative to each other, thereby bending Flexible conductor post 130a. Specifically, compared with the accommodating space 211 of FIG. 3, since the accommodating space 211a of FIG. It is suitable for being placed in the accommodating space 211a. Furthermore, since the flexible conductive column 130a has flexibility, the first substrate 110 and the second substrate 120 can be inclined relative to each other by bending the flexible conductive column 130a. In this way, the three-dimensional antenna device 100a can conform to the shape of the accommodating space 211a and be smoothly installed in the housing 210a.

In summary, the present invention adopts a three-dimensional antenna device with a flexible conductor post. By bending the flexible conductor post, the relative angle between the first substrate and the second substrate can be changed, thereby making the three-dimensional antenna device conform to the requirements. The shape of the installation space. Therefore, the three-dimensional antenna device of the present invention has the advantage of easy configuration. In addition, since the three-dimensional antenna device of the present invention uses two sets of antennas (ie, the first antenna and the second antenna), the signal transmission strength is also better than that of a two-dimensional antenna. Since the present invention adopts the carrier with the above-mentioned three-dimensional antenna device, the structure of the three-dimensional antenna device does not need to be redesigned due to the change of the shape of the housing, and further has the advantage of low cost.
