[0027] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0028] In related technologies, when using a single-turn coil as an antenna, the coil inductance is relatively low. This low inductance leads to a shorter communication distance and weakened anti-interference capability. Furthermore, some existing devices require EMV certification, which mandates that the coil inductance meet the certification requirements. If the antenna's coil inductance is too low, the generated magnetic field strength will also fail to meet EMV certification requirements, resulting in failure. For example, financial POS devices have specific requirements for the coil inductance of NFC antennas. Increasing the coil inductance increases costs and complicates the wiring of the antenna within the casing.

[0029] To solve the above-mentioned technical problems, this utility model provides an antenna structure, an antenna device, and an electronic device, as detailed below:

[0030] An antenna structure includes a main body and two feed sections respectively connected to the main body; the two feed sections are intertwined to increase the inductance of the antenna structure.

[0031] As can be seen from the above description, the beneficial effects of this utility model are as follows: the antenna structure is composed of the main body and two feed parts, and the two feed parts are intertwined to make the two feed parts closer together, thereby making the coupling degree of the antenna structure higher and thus improving the inductance of the antenna structure.

[0032] Furthermore, the main body has a single-ring structure.

[0033] As can be seen from the above description, by setting the main body as a single-loop ring structure, compared with the traditional antenna which needs to be mounted along the surface of the device, the single-loop ring antenna structure can be fitted onto the relevant device, thereby improving the assembly efficiency of the antenna structure and the relevant device.

[0034] Furthermore, the ring structure includes two endpoints, which serve as feed points; each feed point is connected to one of the power supply units.

[0035] As described above, by using the endpoints of the ring structure as feed points and connecting each feed point to a feed section, and winding the feed section at the feed point position, the inductance of the antenna can be increased more effectively.

[0036] Furthermore, the power supply unit includes a wire; one end of the wire is connected to the main body; the other end of the wire is intertwined with another wire and used to input an electrical signal.

[0037] As described above, using wires as the power supply section allows for the effective input of electrical signals to the main body. Furthermore, winding two wires together makes the two power supply sections more closely connected, thereby increasing the inductance.

[0038] Furthermore, the main body is provided with positioning holes; the positioning holes are used for connection with external structures.

[0039] As described above, by providing positioning holes on the main body, the antenna structure can be positioned and fitted with the external structure when it is mounted on the external structure, thus playing a positioning role in the installation of the antenna structure.

[0040] Furthermore, the positioning holes are located at different positions on the main body.

[0041] As can be seen from the above description, by setting positioning holes at different positions on the main body, the antenna structure can be positioned through the positioning holes at different positions, thereby improving the positioning effect of the antenna structure.

[0042] Furthermore, the main body includes a PET film; the inner side of the PET film is used to adhere to the outer surface of the external structure.

[0043] As described above, PET film can provide support for the antenna, thus avoiding the inability to shape the antenna due to its soft overall structure, which would make it difficult to attach to the external structure.

[0044] An antenna device includes a housing and the antenna structure described above; the antenna structure is disposed within the housing.

[0045] As described above, placing the antenna structure within the housing enables the device to communicate with other devices via the antenna structure; furthermore, the antenna structure has a high inductance, thereby giving the antenna device a longer communication distance and anti-interference capability, thus improving communication quality.

[0046] Furthermore, the main body of the antenna structure is fitted onto the inner wall of the housing.

[0047] As can be seen from the above description, by fitting the main body of the antenna structure onto the inner wall of the housing, compared with the traditional antenna which needs to be mounted along the surface of the device, the above-mentioned loop antenna structure can fit the antenna structure onto the relevant device, thereby improving the assembly efficiency of the antenna structure and the housing.

[0048] Furthermore, positioning posts are provided on the bottom and inner sidewall of the housing; the positioning holes of the antenna structure are connected to the positioning posts.

[0049] As described above, by setting positioning posts on the bottom and inner sidewalls of the housing, and by cooperating with positioning holes at different positions on the antenna structure, the antenna structure can be positioned.

[0050] An electronic device includes the aforementioned antenna structure. The electronic device can be a mobile phone, tablet, or POS machine, etc. By mounting the antenna structure onto the housing of the electronic device and connecting it to the device's circuitry, the electronic device gains communication capabilities.

[0051] The antenna structure, device, and electronic equipment provided by this utility model can be applied to smart devices, such as mobile phones, tablets, and POS machines. The following detailed embodiments illustrate these applications:

[0052] Example 1

[0053] Please refer to Figures 1 to 4 An antenna structure 100 includes a main body 101 and two feed sections 102 respectively connected to the main body 101; the ends of the two feed sections 102 away from the main body 101 are intertwined. The antenna structure 100 can be integrally formed, meaning the main body 101 and the two feed sections 102 are a single coil, with the middle portion of the coil serving as the main body 101 and the two ends serving as the feed sections 102. Twisting the two feed sections 102 together forms a ring structure, allowing the antenna to be wound around the inner wall of a housing 200 of equipment such as a POS machine. After the antenna structure 100 is fitted onto the housing 200, refer to... Figure 2 Alternatively, 4G antenna 1 and WIFI antenna 2 can be extended onto the antenna structure 100 and directly attached to the side wall of the housing 200 using adhesive tape or other methods. In other optional embodiments, the antenna structure 100 can be fixed by cutting a groove in the housing 200; or the antenna structure 100 can be sleeved on the outer surface of the external structure; for example, the antenna structure 100 can be sleeved on the outer wall of the paper tray.

[0054] Please refer to Figure 1 as well as Figure 2 In this embodiment, the main body 101 is a single-ring structure, and the ring structure includes two ends, which serve as feed points respectively; each feed point is connected to a feed section 102, and the two feed sections 102 are screwed together and connected to the antenna end of the main board. Figure 2 As shown, this is the state before the entanglement; as Figure 3 As shown, this is the coiled state. During connection, the two feed sections 102 need to be twisted together near the point where they intersect to increase the inductance of the coil. In an optional embodiment, the feed section 102 includes a wire; one end of the wire is connected to the main body 101; the other end of the wire is twisted together with another wire and used to input an electrical signal.

[0055] The main body 101 is provided with positioning holes 103; the positioning holes 103 are used for connection with external structures; and the positioning holes 103 are provided at different positions on the main body 101; for example Figure 2 As shown, for example, when the antenna structure 100 is fitted onto a rectangular shell, it includes four sides; each side is provided with a positioning hole 103; at the same time, the positioning hole 103 can be set on the feed end.

[0056] The antenna structure 100 described above is installed within a specific device structure, specifically:

[0057] Please refer to Figure 4An antenna device includes a housing 200 and the aforementioned antenna structure 100; the antenna structure 100 is disposed within the housing 200. The main body 101 of the antenna structure 100 is fitted onto the inner sidewall of the housing 200. Positioning posts 201 are provided on the bottom and inner sidewall of the housing 200; positioning holes 103 of the antenna structure 100 are connected to the positioning posts 201. In other optional embodiments, the housing 200 can be a paper tray, and the antenna structure 100 is fitted onto the outer sidewall of the paper tray to form the antenna device.

[0058] Please refer to Figure 5 The main body includes a PET film; the PET film is used to cover the inner wall of the housing 200. The PET film provides support for the antenna; it prevents the antenna from being difficult to mount onto the housing 200 due to the overall soft structure failing to provide proper shaping.

[0059] An electronic device includes the aforementioned antenna structure 100. The electronic device can be a mobile phone, tablet, or POS machine, etc. By mounting the antenna structure 100 onto the housing 200 of the electronic device and connecting it to the mainboard circuitry, the electronic device gains communication capabilities; or by mounting the antenna structure 100 onto the outer wall of a paper tray to form an antenna device, and then placing the antenna device inside the POS machine, the POS machine gains communication, payment, and printing functions in addition to these.
