[0028] Near Field Communication (NFC) antennas transmit electromagnetic signals through near-field coupling and are widely used in electronic devices for applications such as mobile payments and identity verification. However, the need for current electronic devices to achieve multiple functions within limited space significantly compresses the location of NFC antennas. This not only easily interferes with other electronic components in the device, but also makes it difficult for the NFC antennas themselves to meet the performance requirements of testing, such as those required for Felica certification.

[0029] The present disclosure provides a near field communication antenna. Figure 1 is a structural diagram of a near field communication antenna in an exemplary embodiment of the present disclosure, Figure 2 FIG. 1 is a schematic diagram of an assembly structure of a near field communication antenna and a camera module in an exemplary embodiment of the present disclosure. Figure 1 、 Figure 2 As shown, the NFC antenna 1 is assembled to the base frame of the camera module 2 and includes a ferrite 111 and a trace 12. Along the optical axis of the camera body 21 of the camera module 2, the ferrite 111 has a relief notch 112 corresponding to the position of the camera body 21. The trace 12 includes a functional section 122 containing a current zero point and a main section 121 connected to the functional section 122. The functional section 122 deforms relative to the main section 121.

[0030] The NFC antenna 1 is assembled to the base of the camera module 2, which provides mounting space for the NFC antenna 1 to achieve expected performance. The trace 12 of the NFC antenna 1 includes a functional section 122 containing a current zero point and a main section 121 connected to the functional section 122. The functional section 122 deforms relative to the main section 121, dispersing the energy concentrated therein and thus reducing the interference of the NFC antenna 1 with the camera body 21. Electronic devices using the NFC antenna 1 and camera module 2 combine the performance of the NFC antenna 1 and the camera module 2 that meet expected standards, thereby helping to enhance the intelligence and user experience of electronic devices.

[0031] In some embodiments, the base frame includes a camera trim 23, to which the NFC antenna 1 is assembled. Because the camera trim 23 is located near the exterior of the electronic device, its location and structural foundation provide mounting space for the NFC antenna 1, enabling the NFC antenna 1 to achieve its intended performance. For example, devices supporting Felica must be certified and authorized by Felica. The card emulation area and card swipe success rate of the NFC antenna 1 must meet Felica certification standards.

[0032] In the above embodiment, the NFC antenna 1 can be assembled on the side of the camera decoration 23 facing away from the camera body 21 to be close to the outside of the electronic device, thereby increasing the card simulation area and the card swiping success rate.

[0033] For example, a mounting groove can be provided on the side of the camera decorative member 23 facing away from the camera body 21, and the ferrite 111 and the wiring 12 can be assembled in the mounting groove. The wiring 12 can be coiled around the edge of the wiring 12, and the ferrite 111 and the wiring 12 cooperate to realize the function of the near-field communication antenna 1.

[0034] In some embodiments, as Figure 3 As shown, the camera trim 23 may include a plastic body 232, a plastic inner ring 231, and a plastic bracket 233. The plastic body 232 is disposed on the periphery of the plastic bracket 233, and the plastic inner ring 231 is disposed on top of the plastic body 232 and the plastic bracket 233 in the direction of the optical axis. The near-field communication antenna 1 may be disposed on the side of the plastic inner ring 231 facing away from the camera body 21. Furthermore, a PVD coating 234 may be provided on the outer surfaces of the plastic inner ring 231 and the plastic body 232 to enhance the aesthetics of the camera trim 23.

[0035] In some embodiments, the functional section 122 includes a first section 1221, the main section 121 includes a second section 1211 connected to the first section 1221, and the first section 1221 is bent relative to the second section 1211. The bending of the first section 1221 relative to the second section 1211 disperses the energy concentration at the current zero point in the first section 1221, thereby reducing magnetic interference with the camera module 2.

[0036] The first section 1221 may be an arc-shaped structure bent relative to the second section 1211 to facilitate structural configuration and achieve a better dispersion effect on concentrated energy. For example, the first section 1221 may be C-shaped.

[0037] Alternatively, the first section 1221 is a rectangular structure, a polygonal structure, or an irregularly shaped structure that is bent relative to the second section 1211 , which can also achieve a corresponding dispersion effect for concentrated energy, and the present disclosure is not limited to this.

[0038] In other embodiments, the functional section 122 includes a third section 1222, and the main body section 121 includes a fourth section 1212 connected to the third section 1222. The cross-sectional area of the third section 1222 is smaller than the cross-sectional area of the fourth section 1212. The reduction in cross-sectional area can disperse the concentrated energy at the current zero point in the third section 1222, thereby reducing magnetic interference with the camera module 2.

[0039] The trace 12 can be arranged around the periphery of the camera body 21, with the third section 1222 recessed relative to the fourth section 1212 on the side facing the camera body 21, creating a clearance gap that keeps the third section 1222 away from the camera body 21. By reducing the cross-sectional area of the third section 1222 relative to the fourth section 1212, the recessed area allows the third section 1222, containing the current zero point, to be positioned as far away from the camera body 21 as possible, reducing electromagnetic interference with the camera body 21. The trace 12 can be arranged symmetrically around the periphery of the camera body 21 to ensure the performance of the near-field communication antenna 1. The recessed third section 1222, located near the camera body 21, relative to the fourth section 1212, allows the trace 12 to maintain a symmetrical arrangement while remaining away from the camera body 21.

[0040] Furthermore, the third section 1222 can be bent relative to the fourth section 1212. The third section 1222 can enhance the effect of breaking up the concentrated energy at the current zero point in the third section 1222 through the reduction of the cross-sectional area and the deformation caused by the bending relative to the fourth section 1212, thereby further reducing the magnetic interference to the camera module 2.

[0041] Furthermore, the third section 1222 can be located at a corner of the camera module 2 and adjacent to the camera body 21. The functional section 122 includes multiple stacked third sections 1222, which are recessed relative to the fourth section 1212 and stacked to form a clearance space. The stacked third sections 1222 can increase the degree of recessing, and the stacked recesses can create a larger clearance space relative to the camera body 21, further reducing electromagnetic interference with the camera body 21.

[0042] In the above embodiment, the camera module 2 may include three camera bodies 21 and a flash 22. The ferrite 111 is provided with clearance notches 112 to allow for the camera bodies 21 and flash 22 to pass through, forming a non-uniformly distributed structure. The arrangement of the traces 12 in the ferrite 111 with the clearance notches 112 disperses energy at the current zero point, maintaining the performance of the near-field communication antenna 1 while preventing electromagnetic interference from the near-field communication antenna 1 on the camera body 21.

[0043] Take the example where the functional section 122 includes the first section 1221 and the third section 1222, and the main section 121 includes the second section 1211 and the fourth section 1212. Among them, the wiring 12 is arranged on the periphery of the camera body 21, the first section 1221 is an arc-shaped structure bent relative to the second section 1211, the cross-sectional area of the third section 1222 is smaller than the cross-sectional area of the fourth section 1212, and the third section 1222 is recessed relative to the fourth section 1212 on the side facing the camera body 21. The third section 1222 is located at the corner of the camera module 2 and is adjacent to the camera body 21. The functional section 122 includes a plurality of stacked third sections 1222, and the plurality of third sections 1222 are recessed relative to the fourth section 1212 and overlap to form an avoidance space. After energy dispersion is performed on the two current zero points of the wiring 12 in the first section 1221 and the third section 1222, the camera module 2 is tested and the following is obtained. Figure 4 As shown in the test result diagram, the camera module 2 can meet the expected standards during use. Figure 5 As shown in the test result diagram, the near field communication antenna 1 can meet the Felica test standard during use.

[0044] The present disclosure further provides an electronic device, which includes a camera module 2 and the above-mentioned near-field communication antenna 1. The camera module 2 includes a base frame and a camera body 21 assembled on the base frame. The near-field communication antenna 1 is assembled on the base frame.

[0045] The near-field communication antenna 1 is assembled on the base of the camera module 2, and the base of the camera module 2 provides an installation space for the near-field communication antenna 1 that can achieve the expected performance. The trace 12 of the near-field communication antenna 1 includes a functional section 122 containing a current zero point and a main section 121 connected to the functional section 122. The functional section 122 deforms relative to the main section 121, dispersing the energy concentrated therein, thereby reducing the interference of the near-field communication antenna 1 on the camera body 21. Electronic devices using the above-mentioned near-field communication antenna 1 and camera module 2 have both the performance of the near-field communication antenna 1 and the performance of the camera module 2 that meet the expected standards, thereby helping to enhance the intelligence and user experience of electronic devices.

[0046] It should be noted that the above-mentioned electronic device can be one of a mobile phone, a tablet computer, a computer, a vehicle-mounted device, a medical device, a wearable device, and a robot, and the present disclosure is not limited to this.
