Please refer to Figures 1 and 2, Figure 2 is a view of the electronic device 100 in Figure 1 observed from the side of the battery cover 30. The battery cover 30 is disposed on the side of the middle frame assembly 20 away from the display screen 10, and can be connected to the frame 22, such as the first frame 221, the second frame 222, the third frame 223 and the fourth frame 224, and is disposed opposite to the substrate 21.

In some embodiments, the battery cover 30 is provided with a camera metal decoration 31 to cooperate with the rear camera 50.

In some embodiments, the circuit board 40 is sandwiched between the substrate 21 and the battery cover 30.

It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

Please refer to FIG3, which is a view of the electronic device 100 in FIG1 observed from the side of the battery cover 30 in another embodiment. The electronic device 100 may further include a non-near field communication antenna 60 and a near field communication antenna 70. The non-near field communication antenna 60 and/or the near field communication antenna 70 cooperate to achieve communication with an external device.

The non-near field communication antenna 60 may include one or more of a cellular antenna, a wireless fidelity (Wireless Fidelity, Wi-Fi) antenna, a global positioning system (Global Positioning System, GPS) antenna, a Bluetooth (Bluetooth, BT) antenna, etc. The near field communication antenna 70 uses NFC (Near Field Communication, near field communication) technology, and NFC is a very short-range wireless radio frequency identification communication protocol technology standard. The NFC signal transmission range is small, but the transmission is fast and the energy efficiency is low. The NFC communication function is set on the electronic device 100, which can play the role of airport boarding verification, access control key, transportation card, credit card, payment card, etc.

It should be noted that in the non-near field communication antenna 60, the signal frequency of the cellular antenna may be above 700MHz, the signal frequency of the wireless fidelity antenna may include 2.4GHz (gigahertz) or 5GHz, the signal frequency of the global positioning system antenna may include 1.575GHz, 1.227GHz, 1.381GHz, 1.841GHz and one or more frequency bands, and the signal frequency of the Bluetooth antenna may include 2.4GHz. The signal frequency of the near field communication antenna 70 may include 13.56MHz (megahertz). Therefore, relative to the cellular antenna, the wireless fidelity antenna, the global positioning system antenna and the Bluetooth antenna, the signal of the near field communication antenna 70 is a low frequency signal, while the signal of the cellular antenna, the signal of the wireless fidelity antenna, the signal of the global positioning system antenna and the signal of the Bluetooth antenna are all high frequency signals. It can be further understood that the signal of the non-near field communication antenna 60 is a high frequency signal, and the signal of the near field communication antenna 70 is a low frequency signal. The signal frequency of the non-near field communication antenna 60 is greater than the signal frequency of the near field communication antenna 70. Furthermore, the non-near field communication antenna 60 can also be a high frequency antenna whose other signals are high frequency signals.

In some embodiments, the cellular antenna operates in a frequency band of 1710MHz-6000MHz, which is used for the fourth generation mobile communication technology (4G) and 5G communications of electronic devices.

The non-near field communication antenna 60 may be a mixture of one or more of a flexible printed circuit (FPC) antenna, a laser direct structuring (LDS) antenna, a print direct structuring (PDS) antenna, and a metal frame antenna. Of course, the non-near field communication antenna 60 may also be other types of antennas, which will not be described in detail. The embodiment of the present application is introduced by taking a metal frame antenna as an example.

Please refer to FIG. 4, which is a schematic diagram of the structure of the middle frame assembly 20, the circuit board 40, the non-near field communication antenna 60 and the near field communication antenna 70 in FIG. 3. The non-near field communication antenna 60 may include at least a first radiator 61 at least partially disposed on the frame 22, such as the first frame 221, and a second radiator 62 at least partially disposed on the frame 22, such as the second frame 222.

In some embodiments, the first radiator 61 may be closer to one side of the second frame 222 than the orthographic projection of the camera metal decorative member 31 on the frame 22, such as the first frame 221, thereby reducing the influence of the camera metal decorative member 31 on the antenna performance of the first radiator 61. In some embodiments, the orthographic projection of the camera metal decorative member 31 on the frame 22, such as the first frame 221, may be located on one side of the first radiator 61 close to the fourth frame 224. That is, the first radiator 61 may be located on one side of the orthographic projection of the camera metal decorative member 31 on the frame 22, such as the first frame 221, close to the second frame 222.

In some embodiments, the second radiator 62 may be partially disposed on the frame 22, such as the first frame 221, and may be partially disposed on the frame 22, such as the second frame 222. In some embodiments, the second radiator 62 may partially extend in the extension direction of the first frame 221, and may partially extend in the extension direction of the second frame 222.

In some embodiments, the second radiator 62 may be entirely disposed on the frame 22, such as the second frame 222. In some embodiments, the second radiator 62 entirely extends in the extension direction of the second frame 222.

4 and 5 , the second radiator 62 may be provided with a third wiring portion 6201 and a fourth wiring portion 6202 . The third wiring portion 6201 and the fourth wiring portion 6202 are provided in coordination to enable the excitation signal to flow through the second radiator 62 .

In some embodiments, the third wiring portion 6201 can be used for grounding, and can also be referred to as a grounding portion. In some embodiments, the third wiring portion 6201 can be used for electrically connecting a feed source, and can also be referred to as a feed portion.

In some embodiments, the second radiator 62 may include a first radiating branch 621 disposed on the frame 22, such as the first frame 221, and a second radiating branch 622 disposed on the frame 22, such as the second frame 222. The first radiating branch 621 may be connected to the second radiating branch 622 at a location where the first frame 221 and the second frame 222 are connected.

In some embodiments, the third wiring portion 6201 may be disposed on the first radiation branch 621. In some embodiments, the fourth wiring portion 6202 may be disposed on the second radiation branch 622. In some embodiments, the effective electrical length of the second radiation branch 622 is 26 mm.

3 , the NFC antenna 70 may include a first radiator 61, a second radiator 62, a conductor 71 and a NFC chip 72. The NFC antenna 70 may not be limited to the first radiator 61 and the second radiator 62, but may also include other parts other than the NFC antenna 60, which will not be described in detail herein.

The conductor 71 cooperates with at least part of the non-near field communication antenna 60, such as the first radiator 61 and the second radiator 62, to form a near field communication radiator. The near field communication antenna 70 and the non-near field communication antenna 60 reuse the radiator, which can save the accommodation space 101 while improving the antenna performance of the near field communication antenna 70. The near field communication chip 72 is used to provide a differential excitation current for exciting the near field communication radiator. The differential excitation current includes two current signals. The two current signals have the same amplitude and opposite phases, or it can be understood that the phases of the two current signals differ by 180 degrees. In addition, the differential excitation current is a balanced signal. It can be understood that during the transmission process, if an analog signal is directly transmitted, it is an unbalanced signal; if the original analog signal is inverted, and then the inverted analog signal and the original analog signal are transmitted at the same time, the inverted analog signal and the original analog signal are called balanced signals. During the transmission process, the balanced signal passes through the differential amplifier, and the original analog signal and the inverted analog signal are subtracted to obtain the enhanced original analog signal. Since the two transmission lines are subject to the same interference during the transmission process, the same interference signal is subtracted during the subtraction process, so the balanced signal has better anti-interference performance.

Referring to FIG. 4 , the conductor 71 may be disposed on the circuit board 40. Specifically, it may be located on the side of the circuit board 40 facing the battery cover 30. In some embodiments, the conductor 71 may be a conductive coating formed by metal plating on the surface of the circuit board 40, and then formed on the surface of the circuit board 40 facing the battery cover 30. In some embodiments, the conductor 71 may be a flexible circuit board disposed on the circuit board 40. In some embodiments, the conductor 71 may be a laser direct forming conductor disposed on the circuit board 40 using laser direct forming technology. In some embodiments, the conductor 71 may be a printed direct forming conductor disposed on the circuit board 40 using printed direct forming technology.

5 , the conductor 71 may have a connection portion 7101 and a connection portion 7102. In some embodiments, the connection portion 7101 and the connection portion 7102 may be located at both ends of the extension direction of the conductor 71. Of course, the connection portion 7101 and the connection portion 7102 may also be disposed at other locations of the conductor 71.

Referring to FIG. 4 , the conductor 71 is disposed on a portion of the circuit board 40 near the first frame 221, so as to be spaced apart from the first frame 221, thereby making full use of the clearance area between the circuit board 40 and the first frame 221. The clearance area refers to an area configured so that magnetic lines of force can pass smoothly without being excessively affected or obstructed.

Please refer to FIG. 3 , the orthographic projection of the conductor 71 on the first frame 221 is located on the side of the first radiator 61 close to the second frame 222, and is spaced apart from the first radiator 61, so that the first radiator 61 can perform near field communication with the conductor 71, increasing the length of the near field communication radiator in the extension direction of the first frame 221, thereby enhancing the antenna performance. Of course, the orthographic projection of the conductor 71 on the first frame 221 can also be arranged crosswise with the first radiator 61, and closer to the second frame 222 than the first radiator 61.

In some embodiments, the effective electrical length of the conductor 71 is 28 mm, which cooperates with the first radiation branch 621 so that the effective electrical length of the near-field communication radiator on the first frame 221 is the sum of 28 mm and 10 mm, specifically 38 mm, which is greater than 35 mm, thereby enhancing the antenna performance and compensating for the low antenna performance caused by the short effective electrical length of the first radiator 61 caused by the camera metal decorative part 31.
