It is understood that the second signal may be different from the first signal. For example, when the first signal is a cellular signal such as a 3G signal, a 4G signal, a 5G signal, etc., the second signal may be a GPS signal, and at this time, the first radiator 200 and at least a portion of the metal bezel 100 may jointly transmit the GPS signal.

It is understood that the second signal may be grounded from the first ground point 110 or the second ground point 120 of the metal bezel 100 to achieve multiplexing of ground points.

When the first radiator 200 transmits the second signal, the second signal may return to the ground from the first feeding point 130 of the metal bezel 100. At this time, the electronic device 10 may further include a ground plane (not shown) and a first frequency selecting circuit LC 1.

At this time, the first frequency selecting circuit LC1 may be a band pass frequency selecting circuit, and the first frequency selecting circuit LC1 may allow the second signal to pass therethrough and may prevent the first signal having a higher frequency than the second signal from passing therethrough.

By providing the first frequency-selective circuit LC1, on one hand, the electronic device 10 according to the embodiment of the application may ground the second signal fed into the metal frame 100 through electromagnetic coupling from the second end of the first frequency-selective circuit LC1, so as to implement transmission of the second signal; on the other hand, the first signal fed by the first feed 300 does not return to the ground from the second end of the first frequency-selecting circuit LC1, and therefore, the transmission of the first signal is not affected, and the first frequency-selecting circuit LC1 can reduce the interference of the transmission of the first signal and the second signal on the metal frame 100.

With reference to fig. 2, when the first radiator 200 transmits the second signal, the second signal may return to the ground from the first ground point 110 in addition to the first feeding point 130, and at this time, the second signal may have two return points. The electronic device 10 may further include a second frequency-selective circuit LC 2.

The second frequency-selecting circuit LC2 may also include a first inductor L1, a first capacitor C1, a second inductor L2, a second capacitor C2, as in the first frequency-selecting circuit LC1, and will not be described in detail herein.

It is understood that the band-pass and band-stop frequencies of the second frequency selection circuit LC2 can be adjusted by adjusting specific values of capacitance, resistance and inductance of the second frequency selection circuit LC2, and the details are not described herein.

According to the second frequency selecting circuit LC2 of the embodiment of the application, only the first signal and the second signal can return to the ground through the second frequency selecting circuit LC2, other clutter signals except the first signal and the second signal cannot return to the ground through the second frequency selecting circuit LC2, and other clutter signals cannot form a current loop and cannot form resonance influencing the transmission of the first signal and the second signal, so that the interference of the clutter signals on the first signal and the second signal can be reduced.

In addition, in the electronic device 10 according to the embodiment of the application, when the first radiator 200 and at least a part of the metal bezel 100 realize electromagnetic coupling through the first gap and are used for transmitting the second signal, the second signal may return to the ground through the first grounding point 110, and the second signal may also return to the ground through the first feeding point 130, on one hand, the first grounding point 110 and the first feeding point 130 realize multiplexing, so that the number of return points arranged on the metal bezel 100 can be reduced, and the structure is simplified; on the other hand, providing two return points can define the flow path of the second signal on the metal frame 100, so that the metal frame 100 and the first radiator 200 have a relatively fixed radiation pattern when transmitting the second signal; also, when the second signal is a GPS signal, the electronic device 10 has a better radiation pattern when transmitting the GPS signal.

It should be noted that the second signal may also return to the ground at two other locations on the metal bezel 100 besides the first feeding point 130 and the first grounding point 110, which is not described in detail herein.

Please refer to fig. 5, wherein fig. 5 is a schematic structural diagram of a third electronic device according to an embodiment of the present disclosure. The electronic device 10 of the embodiment of the present application may further include a second radiator 500 and a third feed 600.

The second radiator 500 may be disposed in the annular metal frame 100 like the first radiator 200, so as to save the space occupied by the second radiator 500. The second radiator 500 may be spaced apart from the metal bezel 100 and a second gap (not shown) may be formed therebetween. A third feeding point 510 may be disposed on the second radiator 500, and the second radiator 500 may be electrically connected to the third feed 600 through the third feeding point 510. The third feed 600 may provide a third driving signal, the third feed point 510 may receive the third driving signal, the third driving signal may achieve electromagnetic coupling between the second radiator 500 and at least part of the metal bezel 100 through the second gap, so that the second radiator 500 may achieve electromagnetic coupling with at least part of the metal bezel 100 through the second gap, and the second radiator 500 and at least part of the metal bezel 100 may jointly transmit the third signal.

It is to be understood that the third signal may be grounded from at least one of the first ground point 110 and the second ground point 120 of the metal bezel 100; a fourth ground point (not shown) may be additionally disposed on the metal frame 100, and the third signal may be grounded from the fourth ground point. The embodiment of the present application does not specifically limit the grounding point of the third signal.

It is understood that the third signal may be different from the first signal, the second signal. For example, when the first signal is a cellular signal such as a 3G signal, a 4G signal, a 5G signal, etc., and the second signal is a GPS signal, the second radiator 500 and at least a portion of the metal bezel 100 may transmit a Wi-Fi signal together.

In the electronic device 10 of the embodiment of the application, the metal frame 100 transmits the first signal, the second radiator 500 transmits the third signal together with the metal frame 100 through electromagnetic coupling, the third signal can be transmitted through the metal frame 100, and the radiation efficiency of the third signal is better, so that the antenna performance of the electronic device 10 is better.

Please refer to fig. 6, where fig. 6 is a schematic diagram of a fourth structure of an electronic device according to an embodiment of the present disclosure. In the electronic device 10 of the embodiment of the application, the third signal may return to the ground from the first ground point 110 and the second ground point 120 of the metal bezel 100, and the second frequency-selecting circuit LC2 may also allow the third signal to pass through.

It can be understood that, when the third signal is received from the first ground point 110 of the metal frame 100, in this case, the first ground point 110 may serve as a return point for the first signal, a return point for the second signal, and a return point for the third signal.

It is to be appreciated that when the second frequency selective circuit LC2 is coupled between the first ground point 110 and the ground plane, the second frequency selective circuit LC2 may allow the first signal, the second signal, and the third signal to pass through, while blocking signals other than the first signal, the second signal, and the third signal from passing through, to avoid interference of spurious signals other than the first signal, the second signal, and the third signal.

As shown in fig. 6, when the third signal goes back to ground from the second ground point 120 of the metal bezel 100, the second ground point 120 may allow the first signal and the third signal to go back to ground.

In the electronic device 10 according to the embodiment of the application, when the second radiator 500 and at least a part of the metal frame 100 are electromagnetically coupled through the second gap and used for transmitting the third signal, the third signal may return to the ground through the first ground point 110 and the second ground point 120, on one hand, the first ground point 110 and the second ground point 120 are reused, so that the number of return points arranged on the metal frame 100 can be reduced, and the structure is simplified; on the other hand, providing two return points may define the flow path of the third signal on the metal bezel 100 to avoid interference of the third signal with the first signal.

In addition, in the electronic device 10 according to the embodiment of the application, the interference is reduced by the first frequency selection circuit LC1, the second frequency selection circuit LC2, and the third frequency selection circuit LC3, and compared with a scheme using an active switch, on one hand, the design of the frequency selection circuit is more flexible, and a required frequency band can be flexibly tuned; on the other hand, the problems of loss and interference caused by using an active device can be avoided, and the cost advantage is achieved.

To further improve the radiation performance of the electronic device 10, please refer to fig. 7, and fig. 7 is a schematic diagram of a fifth structure of the electronic device according to the embodiment of the present application. The metal bezel 100 may include a first side 101, a second side 102, a third side 103, and a fourth side 104.

The first ground point 110 may be located at a connection point of the first side 101 and the fourth side 104, for example, the first ground point 110 may be located at a right upper corner of the metal frame 100; the second ground point 120 may be located at a connection point of the second side 102 and the fourth side 104, for example, the second ground point 120 may be located at a lower right corner of the metal bezel 100; the first feeding point 130 may be located at a connection of the second side 102 and the third side 103, for example, the first feeding point 130 may be located at a lower left corner of the metal bezel 100.

It can be understood that, when the first ground point 110 is located at the upper right corner of the metal frame 100, the second ground point 120 is located at the lower right corner of the metal frame 100, and the first feeding point 130 is located at the lower left corner of the metal frame 100, the distance between the first feeding point 130 and the first and second ground points 110, 120 is suitable, and through the mutual cooperation of the two ground points, the metal frame 100 can tune different resonances, so that the metal frame 100 can adapt to the low, medium, and high frequency bands of the cellular signal.

With reference to fig. 7, the second feeding point 210 of the first radiator 200 may be disposed at the upper left corner of the electronic device 10. The second feeding point 210 may be disposed corresponding to a connection of the first side 101 and the third side 103, and may be disposed at a distance from the connection.

On one hand, the second signal has a longer radiation area, so that the second signal is convenient to tune; on the other hand, the second signal concentrated on the first side 101 and the third side 103 is not easily held by the user at the same time, and the interference rejection of the second signal can be improved.

With reference to fig. 7, the third feeding point 510 of the second radiator 500 may be disposed at the upper right corner of the electronic device 10, and the third feeding point 510 may be disposed corresponding to the connection point of the first side 101 and the fourth side 104 and may be disposed at an interval from the connection point.

At this time, the second signal is mainly concentrated on the first side 101 and the third side 103, the third signal is mainly concentrated on the fourth side 104, and the third side 103 and the fourth side 104 are arranged opposite to each other, so that the radiation areas of the second signal and the third signal can be far, the isolation between the second signal and the third signal is high, and the mutual interference between the third signal and the second signal is small.

It is understood that the first feeding point 130, the second feeding point 210, and the third feeding point 510 of the embodiment of the present application may be electrically connected to the first feed 300, the second feed 400, and the third feed 600 through a metal dome. For example, metal clips may be soldered to a motherboard/circuit board of the electronic device, and then the metal clips are connected to corresponding feeding points to achieve electrical connection. Also, in order to increase the stability of the feeding contact, the first feeding point 130, the second feeding point 210, and the third feeding point 510 may be added with a laser etching technique, and then spot-welded with a gold-plated copper sheet.

It will be appreciated that the first and second ground points 110, 120 of the embodiments of the present application may also be electrically connected to the ground plane in the same way as the feeding points described above; of course, the grounding point may also adopt other stable and good electric contact modes, such as a locking screw mode. And will not be described in detail herein.

The wearing portion 700 may include a first connecting portion and a second connecting portion, and one end of the second connecting portion away from the metal bezel 100 may be movably connected to the first connecting portion, so as to facilitate detachment of the electronic device 10.
