[0022] In order to enable a more clear understanding of the above-mentioned purposes, features and advantages of the embodiments of the present disclosure, the schemes of the embodiments of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the embodiments of the present disclosure, but the embodiments of the present disclosure can also be implemented in other manners different from those described herein; obviously, the embodiments described in the specification are only a part of the embodiments of the present disclosure, and not all the embodiments.

[0024] At present, the application of NFC technology on mobile terminals has become more and more common. The NFC function mainly relies on the NFC controller chip, and the NFC controller (hereinafter referred to as NFCC) realizes the function of the radio frequency front end, which is mainly responsible for establishing a near field communication link based on a 13.56 MHz carrier between a remote endpoint. The information of NFC is transmitted through electromagnetic induction coupling in the wireless frequency part of the spectrum, and the principle is electromagnetic induction.

[0025] With the development of technology and the evolution of user demand, wireless charging technology has become a standard on flagship phones. The current mainstream wireless charging alliance is WPC (Wireless Power Consortium), which uses the principle of electromagnetic induction to transmit energy between the sending end and the receiving end through the electromagnetic field to achieve wireless charging of electronic devices.

[0026] According to relevant regulations, the working frequency range of mobile and portable wireless charging equipment is 100-148.5 kHz, 6765-6795 kHz, 13553-13567 kHz band, and the rated transmission power does not exceed 80W. The working frequency and related technical parameters shall meet the requirements of "Technical Requirements for Wireless Charging (Power Transmission) Equipment". Therefore, the general working frequency of high-power wireless charging used on mobile phone products is 100-148.5 kHz.

[0027] However, with the increasing demand for mobile phone cameras and the increasing functions of mobile phones, the original structure of the NFC antenna is limited, and the NFC antenna needs to be placed above the battery compartment, which will cause the NFC antenna to conflict with the WPC antenna. Therefore, the NFC antenna needs to be merged with the WPC antenna. However, after merging, the area of the NFC antenna will be greatly increased. According to the principle of NFC antenna radiation, the magnetic field in the middle region of the antenna is weak, and there is a communication blind area.

[0028] Specifically, the theory of radiation of a common NFC antenna is Biot-Savart Law, which is a mathematical relationship between the circulating current I in a circuit element with a length of dl and the magnetic induction intensity B. According to the Biot-Savart Law, the magnetic field intensity of the NFC antenna is inversely proportional to the distance.

[0029] In a related technology, in order to avoid the conflict between the NFC antenna and the WPC antenna, the NFC antenna and the WPC antenna are arranged separately, the NFC antenna is arranged on the right side of the camera module, and the WPC antenna is arranged directly above the battery compartment. In this scheme, the size of the NFC antenna is generally 1000mm 2 * 1400mm According to the Biot-Savart Law mentioned above, the field intensity in the central region of the NFC antenna is relatively strong at this time, but the NFC antenna with this size occupies a large space in the mobile phone.

[0030] In another related technology, the mobile phone product does not have a WPC antenna, but due to structural limitations, the NFC antenna is arranged directly above the battery compartment. In this scheme, the size of the NFC antenna is generally 1000mm 2 * 1400mm Based on the Biot-Savart Law, the field intensity in the central region is still relatively strong at this time.

[0031] In another related technology, it is necessary to combine the NFC antenna and the WPC antenna, and due to the difference in working frequency, the two antennas cannot work with the same coil. Therefore, it is necessary to combine the two coils, but still separate them into two antennas.

[0032] There are two ways to combine. One way is that the WPC antenna surrounds the NFC antenna, and at this time, the size of the NFC antenna is only 100mm 2 * 200mm , which seriously affects the use of NFC function, so this scheme cannot be put into practical application. Another way is also the mainstream way in the related technology, that is, the NFC antenna surrounds the WPC antenna, and at this time, the size of the NFC antenna is at least 2000mm 2 , and the distance r from the central region to the NFC antenna is too large. Even after the superposition of the four edges, the field intensity in the central region is still weak, which leads to the fact that the NFC in this region cannot work.

[0033] Therefore, the present disclosure provides an antenna module, as shown in Figure 1 , which includes a charging antenna unit 10 (i.e., a WPC antenna module) and a communication antenna unit 20 (i.e., an NFC antenna module).

[0034] The charging antenna unit 10 includes a first charging antenna 11 and a second charging antenna 12; the communication antenna unit 20 includes a first communication antenna 21 and a second communication antenna 22.

[0035] The first communication antenna 21 is arranged around the first charging antenna 11, the first charging antenna 11 is arranged around the second communication antenna 22, and the second communication antenna 22 is arranged around the second charging antenna 12. Specifically, the antenna module provided by the embodiment of the present disclosure is located in an electronic device, Figure 1 The first communication antenna 21 is arranged around the first charging antenna 11, the first charging antenna 11 is arranged around the second communication antenna 22, and the second communication antenna 22 is arranged around the second charging antenna 12. Specifically, the antenna module provided by the embodiment of the present disclosure is located in an electronic device,

[0036] The antenna module provided by the embodiment of the present disclosure can integrate NFC and wireless charging functions in the limited space of the electronic device by embedding the NFC antenna and the WPC antenna together, thereby reducing the demand for additional antenna area. Meanwhile, the first communication antenna 21 surrounds the charging antenna unit 10 and serves as a large-size main radiation antenna to meet the basic NFC communication demand; the second communication antenna 22 is embedded in the charging antenna unit 10 and serves as a secondary radiation antenna to supplement the radiation and reduce the communication blind area in the central region, and can also provide radio frequency field energy for small-size tag cards and receive the communication signals thereof; the secondary radiation antenna can work cooperatively with the main radiation antenna to support multiple communication protocols or perform different operations at the same time, thereby enhancing the multifunctionality and adaptability of the system.

[0037] Meanwhile, the second charging antenna 12 is embedded in the second communication antenna 22, which improves the charging efficiency of the antenna and enables the entire antenna module to be applied to wireless charging of large-size and small-size devices. In addition, the smaller second charging antenna 12 can generate a stronger magnetic field to compensate for the insufficient magnetic field strength of the main antenna (i.e., the first charging antenna 11) in the central position, thereby improving the effective working range of the entire charging antenna unit. The smaller second charging antenna 12 can also help to disperse the magnetic field energy and avoid excessive electromagnetic interference caused by the strong magnetic field generated by the single main antenna (i.e., the first charging antenna 11) to the surrounding environment.

[0038] In some embodiments, as shown in FIG. 1A, the first communication antenna 21 and the second communication antenna 22 can be connected in series. Figure 1 In some embodiments, as shown in FIG. 1A, the first communication antenna 21 and the second communication antenna 22 can be connected in series. Figure 2 By supporting both series and parallel connection modes, the flexibility of the antenna module can be enhanced on the basis of cost saving, more application scenarios can be adapted, the antenna performance can be improved, and more frequency bands can be covered by the antenna module.

[0039] Specifically, by supporting both series and parallel connection modes, users can choose the most suitable configuration according to actual needs. For example, when stronger signal transmission distance or higher power is needed, the series mode can be chosen; while when higher data transmission rate or lower power consumption is pursued, the parallel mode can be chosen.

[0040] Different application scenarios have different requirements for NFC antennas. The dual connection mode of the above embodiments enables the antenna module to better adapt to various environments, such as mobile payment terminals, intelligent access control systems, logistics tracking tags, etc., thereby improving the product's versatility and market competitiveness.

[0041] Moreover, in the series mode, the effective length of the two antennas increases, which can improve the distance and strength of signal transmission, especially suitable for far-field communication or complex electromagnetic environments; while the parallel mode can reduce impedance matching difficulty, reduce signal reflection loss, and ensure higher data transmission rate and more stable communication quality.

[0042] Finally, adjusting the working characteristics of the antenna according to different connection modes can to some extent expand its frequency band coverage, so that a single antenna module can meet the needs of multiple frequency bands, such as ISO / IEC 14443 (13.56 MHz) and other potential standard frequencies.

[0043] In some embodiments, as shown in FIG. 1A and FIG. 1B, the first communication antenna 21 and the second communication antenna 22 are both rectangular in shape. Specifically, the first communication antenna 21 and the second communication antenna 22 are both rectangular in shape in the plane of the electronic device. Figure 1 As shown in FIG. 1A and FIG. 1B, the first communication antenna 21 and the second communication antenna 22 are both rectangular in shape. Specifically, the first communication antenna 21 and the second communication antenna 22 are both rectangular in shape in the plane of the electronic device. Figure 2 Specifically, compared with other shapes, the rectangular antenna has smaller edge effects, which means it can maintain a consistent magnetic field strength over a wider area, thereby expanding the effective working area. The rectangular structure is simple and intuitive, making it easy for engineers to accurately design dimensions and parameters. By adjusting parameters such as aspect ratio and number of turns, the desired impedance matching and frequency response characteristics can be easily achieved.

[0044] The rectangular antenna has obvious directivity, i.e., the energy it transmits or receives is mainly concentrated in a specific direction. For NFC applications, this characteristic helps to concentrate energy on the target device, reducing unnecessary scattering and interference. Moreover, in a two-way communication scenario, the rectangular antenna can better form directional coupling with the opposite antenna, ensuring more efficient signal exchange between the two, especially in a multi-antenna system, the rectangular antenna can avoid mutual interference through reasonable layout.

[0045]

[0046] ​Modern mobile devices have limited internal space, and rectangular antennas can be flexibly adjusted in size according to specific requirements, ensuring sufficient radiation area without occupying too much space. In addition, the rectangular design can also make full use of the planar area inside the device, such as the blank part on the PCB board, further optimizing the space utilization.

[0047] The electromagnetic radiation characteristics of rectangular antennas are relatively easy to predict and control, which helps to reduce electromagnetic interference to the external environment and also reduces the possibility of being disturbed by the outside world. This is crucial for improving the electromagnetic compatibility performance of the entire system.

[0048] In some embodiments, as shown in FIG. 1A, the first communication antenna 21 and the second communication antenna 22 are both rectangular in shape, and the first charging antenna 11 and the second charging antenna 12 are both circular in shape. Figure 1 As shown in FIG. 1B, the first communication antenna 21 and the second communication antenna 22 are both rectangular in shape, and the first charging antenna 11 and the second charging antenna 12 are both circular in shape. Figure 2 As shown in FIG. 1C, the first communication antenna 21 and the second communication antenna 22 are both rectangular in shape, and the first charging antenna 11 and the second charging antenna 12 are both circular in shape.

[0049] Specifically, circular antennas can produce a more uniform magnetic field distribution, which is crucial for improving energy transmission efficiency. A uniform magnetic field can ensure that the receiving end antenna receives a relatively consistent energy density throughout the working area, reducing hot spots and blind spots, and thus improving overall charging efficiency.

[0050] Circular antennas have high rotational symmetry, which makes the coupling between them and the receiving end antenna more stable and efficient. Regardless of the angle at which the receiving device is placed, circular antennas can provide consistent coupling effects, reducing position sensitivity and improving user experience.

[0051] In actual use, users may not accurately place the device at the center of the charging plate every time. The design of circular charging antennas allows for good coupling efficiency even if the device is slightly offset from the center position, increasing the convenience and flexibility of use.

[0052] In some embodiments, as shown in FIG. 1A, the first communication antenna 21 and the second communication antenna 22 are both rectangular in shape, and the first charging antenna 11 and the second charging antenna 12 are both circular in shape. Figure 3 As shown in FIG. 1B, the first communication antenna 21 and the second communication antenna 22 are both rectangular in shape, and the first charging antenna 11 and the second charging antenna 12 are both circular in shape.

[0053] In some embodiments, the number of turns of the first communication antenna 21 is greater than the number of turns of the second communication antenna 22, thereby optimizing the overall performance of the communication antenna unit.

[0054] Specifically, the first communication antenna 21 serves as the main radiation antenna, and increasing the number of windings can significantly improve the strength of the magnetic field it generates. More turns mean a longer current path through the antenna, resulting in a stronger magnetic flux and thus enhancing the antenna's radiation capability. A stronger magnetic field enables the main antenna to work effectively at a greater distance, expanding the communication range between the reader and the tag. This is particularly important for application scenarios that require wide coverage, such as public transportation cards, access control systems, etc.

[0055] The main radiation antenna with more turns can provide better energy transmission efficiency, especially in close-range wireless charging or data exchange. A stronger magnetic field and more stable coupling improve the effectiveness of energy transfer, reducing energy loss. Due to the high efficiency of the main radiation antenna, the same effect can be achieved at a lower transmission power, reducing power consumption, prolonging the battery life of the device, and reducing the risk of electromagnetic interference. A strong magnetic field can also help overcome noise and other interference sources in the environment, ensuring the accuracy and integrity of data transmission.

[0056] The second communication antenna 22, as the secondary radiation antenna, uses fewer windings, making it more suitable for performing specific auxiliary tasks such as short-range communication, position detection, or as a backup channel. This design allows the secondary radiation antenna to focus on specific functions without affecting the performance of the main antenna. The weaker magnetic field generated by the secondary antenna with fewer turns reduces self-interference with the main radiation antenna, ensuring system stability and reliability.

[0057] By adjusting the number of windings of the main and secondary radiation antennas, optimal performance configurations can be achieved within limited space, making full use of available space.

[0058] In some embodiments, as shown in FIG. 1, the number of windings of the first communication antenna 21 is 2, and the number of windings of the second communication antenna 22 is 1. Figures 1 to 3

[0062] In some embodiments, the area of the enclosed region formed by the winding of the second communication antenna 22 is greater than or equal to 100 square millimeters, which can effectively compensate for the field strength in the central region and reduce the communication blind area in the central region.

[0063] The present disclosure provides a specific embodiment, such as Figure 4 As shown (the charging antenna unit is not shown), the winding shape of the second communication antenna 22 is a rectangle, the length of the rectangle is 10 mm, the width of the rectangle is 10 mm, the area of the enclosed region formed by the winding of the second communication antenna 22 is 100 square millimeters, which can effectively compensate for the field strength in the central region and reduce the communication blind area in the central region.
