[0002] With the booming development of wireless broadband networks and mobile communication technologies, various electronic products with wireless communication functions (such as mobile phones, tablet computers, or laptop computers) have been widely popularized, resulting in an increase in the number of antenna components with the evolution of communication technologies. However, the available space inside the electronic products does not increase with the increase in antenna components, and the distances between antenna components or between antenna components and other electronic components of the electronic products are also significantly reduced, not only increasing the coupling between antenna components or with other electronic components, but also affecting the performance of the antenna and the quality of communication. This will pose multiple difficult new challenges to designers.

[0003] Therefore, there is an urgent need to provide an electronic device to solve the above problems. Summary of the Invention

The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0035] In order to optimize the internal space, reduce the space occupied by the antenna module, and reduce the signal interference received by the antenna module, this embodiment provides an electronic device 1 that supports multiple different wireless communication standards. The following will be combined with Figures 1 to 5 to describe the specific content of this embodiment in detail.

[0036] As Figures 1 to 4 shown, the electronic device 1 includes a housing 10, a first antenna module 11, and a second antenna module 12.

[0037] Among them, the housing 10 has a side 110, and the side 110 has an accommodation space 120 that can accommodate and place the first antenna module 11 and the second antenna module 12. The accommodation space 120 includes a shared frame 130. The shared frame 130 has a first support portion 21 and a second support portion 22 for placing antenna modules such as the first antenna module 11 and the second antenna module 12. The first antenna module 11 is disposed on the first support portion 21, and the second antenna module 12 is disposed on the second support portion 22. In addition, the shared frame 130 is preferably made of plastic material, but not limited thereto.

[0038] The first antenna module 11 is disposed in the accommodation space 120 and is used to receive or transmit signals in a first frequency band such as the 2.4 GHz frequency band and the 5 GHz frequency band. The second antenna module 12 is disposed in the accommodation space 120 and is used to receive or transmit signals in a second frequency band such as the 13.56 MHz frequency band. In addition, a virtual reference plane RS is defined on the lower end surface of the housing 10. The first antenna module 11 is parallel to the virtual reference plane RS; the second antenna module 12 is perpendicular to the virtual reference plane RS, that is, parallel to the side 110. The projection range of the first antenna module 11 on the virtual reference plane RS and the projection range of the second antenna module 12 on the virtual reference plane RS partially overlap. Since both the first antenna module 11 and the second antenna module 12 are disposed in the accommodation space 120, the placement positions are in an inverted L shape, and the radiation field patterns in the space are orthogonal, so the radio wave interference between them can be greatly reduced. The first antenna module 11 and the second antenna module 12 of two different wireless communication standards are integrated into the same accommodation space 120 and can operate normally.

[0039] In an embodiment of the present invention, the first antenna module 11 is preferably a linearly polarized antenna such as a chip antenna, that is, the radiation field pattern in the space is in a linearly polarized form; the second antenna module 12 is preferably a circularly polarized antenna such as a circularly polarized loop antenna, that is, the radiation field pattern in the space is in a circularly polarized form. Since the radiation field patterns of the first antenna module 11 and the second antenna module 12 in the space have different polarization forms, the radio wave interference between them can be greatly minimized.

[0040] In addition, since the second antenna module 12 is disposed on the side 110 of the housing 10, that is, the induction range is at the position of the side 110. Therefore, the user can easily align the induction card with the RFID function with the induction range (that is, place it in the correct induction position), which can improve the convenience and accuracy of the user during use.

[0041] The second antenna module 12 is preferably composed of a flexible material, such as a flexible printed circuit board. In an embodiment of the present invention, the second antenna module 12 wraps around the second support portion 22 to form an L shape (not shown in the figure), that is, a part of the second support portion 22 is perpendicular to the virtual reference plane RS, and the remaining part is parallel to the virtual reference plane RS. Since the sensing range of the second antenna module 12 extends from the side 110 to the lower or back surface of the housing 10 to form an L shape, compared with the sensing range only at a certain position on the side 110, the convenience and accuracy of the user in use can be greatly improved.

[0042] As Figure 5 shown, the electronic device 1 further includes a first communication circuit 31 coupled to the first antenna module 11 and a second communication circuit 32 coupled to the second antenna module 12. The first communication circuit 31 includes a baseband circuit and a radio frequency circuit, which processes baseband signals and radio frequency signals according to the first communication protocol and communicates (i.e., transmits or receives signals) through the first antenna module 11. The second communication circuit 32 includes a baseband circuit and a radio frequency circuit, which processes baseband signals and radio frequency signals according to the second communication protocol and communicates through the second antenna module 12. The first communication protocol conforms to the wireless local area network communication protocol, and the second communication protocol conforms to the radio frequency identification (RFID) communication protocol. It should be noted that since the first communication circuit 31 and the second communication circuit 32 belong to the category of well-known common sense technologies, they will not be described in detail here.

[0043] In summary, for the electronic device 1 provided by the embodiment of the present invention, the first antenna module 11 and the second antenna module 12 of two different wireless communication standards are disposed in an accommodation space 120 on the side 110 of the housing 10. The first antenna module 11 is disposed on the first support portion 21 of the shared frame 130 in the accommodation space 120 and is parallel to the virtual reference plane RS defined by the lower end surface of the housing 10. The second antenna module 12 is disposed on the second support portion 22 of the shared frame 130 in the accommodation space 120 and is perpendicular to the virtual reference plane RS. Thus, the radiation field patterns of the first antenna module 11 and the second antenna module 12 in space are orthogonal, and the radio wave interference between them is greatly reduced. The first antenna module 11 and the second antenna module 12 of two different wireless communication standards are integrated into the same accommodation space 120.

[0044] Note that the above is only a preferred embodiment of the present invention and the technical principles applied. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, re-adjustments and substitutions can be made by those skilled in the art without departing from the protection scope of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments. Without departing from the concept of the present invention, more other equivalent embodiments can be included, and the scope of the present invention is determined by the scope of the appended claims.
