Electronic devices usually include NFC antenna components for sending and receiving near field communication signals (NFC) to realize the NFC communication function of electronic devices. However, the NFC communication performance of the antenna components in electronic devices in the related art is not good enough and there is still room for improvement. Summary of the invention
[0003] In a first aspect, an embodiment of the present application provides an antenna assembly, wherein the antenna assembly comprises:
[0004] NFC chip;
[0005] Switch module;
[0006] A first radiator, the first radiator being electrically connected to the switch module; and
[0007] a second radiator, the second radiator being spaced apart from the first radiator, and the second radiator being electrically connected to the switch module;
[0008] The switching switch module has a first state and a second state. When the switching switch module is in the first state: the first radiator is electrically connected to the NFC chip through the switching switch module, the second radiator is disconnected from the NFC chip, and the NFC chip sends and receives NFC signals through the first radiator; when the switching switch module is in the second state: the second radiator is electrically connected to the NFC chip through the switching switch module, the first radiator is disconnected from the NFC chip, and the NFC chip sends and receives NFC signals through the second radiator.
[0009] In a second aspect, an embodiment of the present application provides an electronic device, wherein the electronic device includes the antenna assembly as described in the first aspect.
[0010] In summary, the antenna assembly provided in the embodiment of the present application includes an NFC chip, a switch module, a first radiator and a second radiator, wherein the first radiator and the second radiator are both electrically connected to the switch module, and the first radiator and the second radiator are spaced apart. The switch module has a first state and a second state. When the switch is in the first state, the first radiator is electrically connected to the NFC chip through the switch module, and the second radiator is disconnected from the NFC chip, so that the NFC chip sends and receives NFC signals through the first radiator. When the switch is in the second state, the second radiator is electrically connected to the NFC chip through the switch module, and the first radiator is disconnected from the NFC chip, so that the NFC chip sends and receives NFC signals through the second radiator. Since the first radiator and the second radiator are arranged at intervals, the positions of the first radiator and the second radiator are different. When the antenna assembly is applied to an electronic device, the first radiator and the second radiator correspond to different positions of the electronic device, so that a user can hold the electronic device and use the antenna assembly for NFC communication from different angles without holding it in a specific posture, thereby improving the convenience and experience of the user when using the NFC communication function of the antenna assembly.

[0032] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the embodiments described in the present application are only a part of the embodiments, not all of the embodiments. Based on the embodiments provided in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present application.
[0033] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it mutually exclusive, independent, or alternative to other embodiments. It can be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.
[0034] The terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example: a component or device including one or more parts is not limited to the one or more parts listed, but optionally includes one or more parts that are not listed but inherent to the exemplified product, or one or more parts that it should have based on the described function.
[0035] Please also read Figure 1 , Figure 2 and Figure 3 , Figure 1 A schematic diagram of an antenna assembly provided in one embodiment of the present application; Figure 2 for Figure 1 A schematic diagram showing that the switching switch module in the antenna assembly is in a first state; Figure 3 for Figure 1Schematic diagram of the switch module in the antenna assembly in the second state shown in . The antenna assembly 10 includes an NFC chip 100, a switch module 200, a first radiator 400 and a second radiator 500. The first radiator 400 is electrically connected to the switch module 200. The second radiator 500 is spaced apart from the first radiator 400, and the second radiator 500 is electrically connected to the switch module 200. The switch module 200 has a first state and a second state. When the switch module 200 is in the first state: the first radiator 400 is electrically connected to the NFC chip 100 through the switch module 200, the second radiator 500 is disconnected from the NFC chip 100, and the NFC chip 100 sends and receives NFC signals through the first radiator 400. When the switch module 200 is in the second state: the second radiator 500 is electrically connected to the NFC chip 100 through the switch module 200 , the first radiator 400 is disconnected from the NFC chip 100 , and the NFC chip 100 sends and receives NFC signals through the second radiator 500 .
[0036] The NFC chip 100 is also called a Near Field Communication (NFC) chip. The NFC chip 100 is used to generate and transmit an NFC transmission signal, and the NFC chip 100 is used to receive an NFC reception signal through one of the first radiator 400 and the second radiator 500 .
[0037] The switch module 200 may also be referred to as a matching unit. The switch module 200 is electrically connected to the NFC chip 100, and the switch module 200 is also electrically connected to the first radiator 400 and the second radiator 500. Therefore, the state of the switch module 200 may make the radiators electrically connected to the NFC chip 100 different. This will be described in detail later.
[0038] The first radiator 400 is a radiator that supports NFC communication function. The first radiator 400 includes at least one of a coil radiator, a flexible circuit board radiator, and a frame radiator. For example, in one embodiment, the first radiator 400 is a coil radiator. In another embodiment, the first radiator 400 includes an electrically connected coil radiator and a frame radiator. In yet another embodiment, the first radiator 400 includes a frame radiator. The present application does not limit the type of the first radiator 400.
[0039] Correspondingly, the second radiator 500 is a radiator that supports NFC communication function. The second radiator 500 includes at least one of a coil radiator, a flexible circuit board radiator, and a frame radiator. For example, in one embodiment, the second radiator 500 is a coil radiator. In another embodiment, the second radiator 500 includes an electrically connected coil radiator and a frame radiator. In yet another embodiment, the second radiator 500 includes a frame radiator. The present application does not limit the type of the second radiator 500.
[0040] The second radiator 500 is arranged at a distance from the first radiator 400. For example, when the antenna assembly 10 is applied to the electronic device 1, when the electronic device 1 is in a vertical screen state, the first radiator 400 is arranged corresponding to the top of the electronic device 1, and the second radiator 500 is arranged corresponding to the bottom of the electronic device 1. It can be understood that the present application does not limit the positions of the second radiator 500 and the first radiator 400, as long as the second radiator 500 and the first radiator 400 are arranged at a distance. The second radiator 500 is arranged at a distance from the first radiator 400, so the position of the first radiator 400 is different from the position of the second radiator 500. Therefore, when the antenna assembly 10 is applied to the electronic device 1, the first radiator 400 and the second radiator 500 correspond to different positions of the electronic device 1, so that the user can hold the electronic device 1 and use the antenna assembly 10 for NFC communication from different angles without holding it in a specific posture, thereby improving the convenience and experience of the user when using the NFC communication function of the antenna assembly 10.
[0041] Specifically, the switch module 200 has a first state and a second state. When the switch module 200 is in the first state: the first radiator 400 is electrically connected to the NFC chip 100 through the switch module 200, and the second radiator 500 is electrically disconnected from the NFC chip 100. In other words, when the switch module 200 is in the first state, the NFC chip 100 sends and receives NFC signals through the first radiator 400. That is, when the switch 210 is in the first state, the first radiator 400 is a working radiator in the antenna assembly 10 that sends and receives the NFC signal.
[0042] When the switch module 200 is in the second state: the first radiator 400 is electrically disconnected from the NFC chip 100, and the second radiator 500 is electrically connected to the NFC chip 100 through the switch module 200. In other words, when the switch module 200 is in the second state, the NFC chip 100 sends and receives NFC signals through the second radiator 500. That is, when the switch 210 is in the second state, the second radiator 500 is a working radiator in the antenna assembly 10 that sends and receives the NFC signal.
[0043] In summary, the antenna assembly 10 provided in the embodiment of the present application includes an NFC chip 100, a switch module 200, a first radiator 400, and a second radiator 500. The first radiator 400 and the second radiator 500 are both electrically connected to the switch module 200, and the first radiator 400 and the second radiator 500 are arranged at intervals. The switch module 200 has a first state and a second state. When the switch 210 is in the first state, the first radiator 400 is electrically connected to the NFC chip 100 through the switch module 200, and the second radiator 500 is disconnected from the NFC chip 100. In this way, the NFC chip 100 sends and receives NFC signals through the first radiator 400. When the switch 210 is in the second state, the second radiator 500 is electrically connected to the NFC chip 100 through the switch module 200, and the first radiator 400 is disconnected from the NFC chip 100, so that the NFC chip 100 sends and receives NFC signals through the second radiator 500. Since the first radiator 400 and the second radiator 500 are arranged at intervals, the positions of the first radiator 400 and the second radiator 500 are different. When the antenna assembly 10 is applied to the electronic device 1, the first radiator 400 and the second radiator 500 correspond to different positions of the electronic device 1, so that the user can hold the electronic device 1 and use the antenna assembly 10 for NFC communication from different angles without holding it in a specific posture, thereby improving the convenience and experience of the user when using the NFC communication function of the antenna assembly 10.

When the switch module 200 is in the first state, the first end 210a is electrically connected to the first connection end 220a, and the second end 210b is electrically connected to the second connection end 220b. When the switch module 200 is in the second state, the first end 210a is electrically connected to the third connection end 220c, and the second end 210b is electrically connected to the fourth connection end 220d.
[0045] The switch 210 has a first end 210a, a second end 210b, a first connection end 220a, a second connection end 220b, a third connection end 220c, and a fourth connection end 220d. The first end 210a may be electrically connected to the NFC chip 100 in a manner that is, but not limited to, the first end 210a is directly or indirectly electrically connected to the NFC chip 100. The second end 210b may be electrically connected to the NFC chip 100 in a manner that is, but not limited to, the second end 210b is directly or indirectly electrically connected to the NFC chip 100. The first connection end 220a may be electrically connected to the first radiator 400 in a manner that is, but not limited to, the first connection end 220a is directly or indirectly electrically connected to the first radiator 400.

[0046] The switch 210 has two switch states, which are named the first switch state and the second switch state for the convenience of description. When the switch 210 is in the first switch state, the first end 210a is electrically connected to the first connection end 220a, and the second end 210b is electrically connected to the second connection end 220b; when the switch 210 is in the second switch state, the first end 210a is electrically connected to the third connection end 220c, and the second end 210b is electrically connected to the fourth connection end 220d. When the switch 210 is in the first switch state, the switch module 200 is in the first state; when the switch 210 is in the second switch state, the switch module 200 is in the second state.
[0047] It can be seen that in the antenna assembly 10 provided in the embodiment of the present application, the switching switch module 200 includes a switching switch 210, and the switching switch 210 is used to realize the first state and the second state of the switching switch module 200, and the structure is simple and easy. The first state or the second state of the switching switch module 200 can be realized by controlling the state of the switching switch 210.

The NFC chip 100 is used to generate an NFC transmitting signal, and the NFC transmitting signal is output via the first transmitting pin 110a and the second transmitting pin 120a. The first receiving pin 110b and the second receiving pin 120b receive the NFC receiving signal. When the switching switch module 200 is in the first state, the first radiator 400 receives the NFC electromagnetic wave to obtain the NFC receiving signal. When the switching switch 210 is in the second state, the second radiator 500 receives the NFC electromagnetic wave to obtain the NFC receiving signal.

In other words, when the switch module 200 is in the first state, the first radiator 400 is the working radiator of the antenna assembly 10. Correspondingly, when the switch module 200 is in the second state, the second radiator 500 is the working radiator of the antenna assembly 10.

[0132] See also Fig. 20 , Fig. 20 A circuit block diagram of an electronic device provided in an embodiment of the present application. In this embodiment, the electronic device 1 includes, in addition to the antenna assembly 10, a processor 40. The processor 40 is electrically connected to the switching switch module 200 to control the state of the switching switch module 200. In the electronic device 1 provided in the embodiment of the present application, when the electronic device 1 performs NFC communication with the target object, the processor 40 can control the switching switch module 200 to be in one of the first state and the second state, wherein when the switching switch module 200 is in the first state and the second state, the communication performance of the antenna assembly 10 is better than the communication performance of the switching switch 210 when it is in the other of the first state and the second state.

[0136] For further information, please refer to Fig.18 The electronic device 1 has a vertical screen state. When the electronic device 1 is in the vertical screen state, the electronic device 1 has a top 1e and a bottom 1f. The first radiator 400 is arranged corresponding to the top of the electronic device 1, and the second radiator 500 is arranged corresponding to the bottom of the electronic device 1.
[0137] In this embodiment, when the electronic device 1 is in a portrait state, the top portion is located above the electronic device 1 and occupies half of the entire area of the electronic device 1, and the bottom portion is located below the electronic device 1 and occupies half of the entire area of the electronic device 1.
[0138] In another embodiment, when the electronic device 1 is in a portrait state, the top portion is located above the electronic device 1 and occupies one third or approximately one third of the area of the entire electronic device 1, and the bottom portion is located below the electronic device 1 and occupies one third or approximately one third of the area of the entire electronic device 1.
[0139] The electronic device 1 provided in the embodiment of the present application, when the electronic device 1 is in the portrait state, the electronic device 1 has a top and a bottom, the first radiator 400 is arranged corresponding to the top of the electronic device 1, and the second radiator 500 is arranged corresponding to the bottom of the electronic device 1, so that the user can hold the electronic device 1 and communicate with the target object using NFC signals from the top or bottom of the electronic device 1, thereby improving the communication performance of the electronic device 1 using the antenna assembly 10 for NCF communication. The electronic device 1 communicates with the target object using NFC signals, including the electronic device 1 and the target object using NFC signals to swipe or read a card.
[0140] For example, when the top of the electronic device 1 is close to the target object, the switch module 200 switches from the second state to the first state, or the switch module 200 maintains the first state, so as to perform NFC communication using the first radiator 400 located at the top of the electronic device 1. When the bottom of the electronic device 1 is close to the target object, the switch module 200 switches from the first state to the second state, or the switch module 200 maintains the second state, so as to perform NFC communication using the second radiator 500 located at the bottom of the electronic device 1. In this way, the communication performance of the electronic device 1 using NFC signals can be improved.
[0141] It can be seen that in the antenna assembly 10 provided in the embodiment of the present application, the first radiator 400 is arranged corresponding to the top of the electronic device 1, so that the top of the electronic device 1 has an NFC function. The second radiator 500 is arranged corresponding to the bottom of the electronic device 1, so that the bottom of the electronic device 1 has an NFC function. Therefore, the electronic device 1 provided in the embodiment of the present application can realize that any area and any angle of the electronic device 1 has NFC performance.
[0142] The working principles of the antenna assembly 10 of the electronic device 1 provided in the embodiments of the present application in some scenarios are introduced as follows.
[0143] In one embodiment, the target object for communication with the electronic device 1 is a POS machine as an example for description. When the electronic device 1 is held by the user, when the top of the electronic device 1 is close to the POS machine, the first radiator 400 first senses the card reading signal of the POS machine, and the processor 40 controls the switching switch module 200 to be in the first state, or controls the switching switch module 200 to switch from the second state to the first state, and the first radiator 400 is a working radiator to achieve card swiping. When the bottom of the electronic device 1 is close to the POS machine, the second radiator 500 first senses the card reading signal of the POS machine, and the controller controls the switching switch 210 to be in the second state, or controls the switching switch module 200 to switch from the first state to the second state, and the second radiator 500 is a working radiator to achieve card swiping.
[0144] In another embodiment, the target object for communication with the electronic device 1 is a card as an example. The processor 40 of the electronic device 1 periodically controls the switching module 200 to be in a first state and a second state. The switching module 200 periodically switches between the first state and the second state. Since the first radiator 400 is a working radiator when the switching module 200 is in the first state; the second radiator 500 is a working radiator when the switching module 200 is in the second state, the periodic switching of the switching module 200 between the first state and the second state is also called switching between the first radiator 400 and the second radiator 500 to listen to the polling state. If the card is close to the electronic device 1, if the first radiator 400 detects that the card is close, the processor 40 controls the switching module 200 to be in the first state, or switches from the second state to the first state, and the antenna assembly 10 uses the first radiator 400 to complete the NFC card reading. If the second radiator 500 detects that the card is approaching, the processor 40 controls the switch module 200 to be in the second state, or to switch from the first state to the second state, and the antenna assembly 10 uses the second radiator 500 to complete NFC card reading.
[0145] In summary, the electronic device 1 provided in one embodiment of the present application can be held by the user in any posture, without a specific holding posture, to achieve the card swiping function and the NFC card reading function. The electronic device 1 has a larger card swiping and NFC card reading space, and the user experience is better.
[0146] In addition, in the antenna assembly 10 provided in one embodiment of the present application, one NFC chip 100 and one switching switch module 200 are used to realize the switching of the working radiator of the antenna assembly 10 , without the need for two NFC chips 100 , and the cost is lower.
[0147] Furthermore, the electronic device 1 has a first side 1a, a second side 1b, and a third side 1c that are bent and connected in sequence. The third side 1c is arranged opposite to the first side 1a, wherein the length of the first side 1a is less than the length of the second side 1b, and the length of the third side 1c is less than the length of the second side 1b. At least a portion of the first radiator 400 is arranged corresponding to the first side 1a; at least a portion of the second radiator 500 is arranged corresponding to the third side 1c.
[0148] In this embodiment, at least a portion of the first radiator 400 is disposed corresponding to the first side 1a; at least a portion of the second radiator 500 is disposed corresponding to the third side 1c. Therefore, when the electronic device 1 uses the antenna assembly 10 for NFC communication, the first side 1a and the third side 1c of the electronic device 1 have better NFC communication performance.
[0149] For further information, see Fig.19 The first radiator 400 includes an electrically connected first sub-radiator 410 and a second sub-radiator 420. At least a portion of the first sub-radiator 410 is located at the first side 1a, and the second sub-radiator 420 is located between the first side 1a and the third side 1c. The second radiator 500 includes an electrically connected third sub-radiator 510 and a fourth sub-radiator 520, wherein at least a portion of the third sub-radiator 510 is located at the third side 1c, and the fourth sub-radiator 520 is located at the second side 1b.
[0150] In this embodiment, the first radiator 400 includes an electrically connected first sub-radiator 410 and a second sub-radiator 420. At least a portion of the first sub-radiator 410 is located at the first side 1a, and the second sub-radiator 420 is located between the first side 1a and the third side 1c. The second radiator 500 includes an electrically connected third sub-radiator 510 and a fourth sub-radiator 520, at least a portion of the third sub-radiator 510 is located at the third side 1c, and the fourth sub-radiator 520 is located at the second side 1b, so that the electronic device 1 can have a better NFC signal in more areas, and when the electronic device 1 uses the antenna assembly 10 for NFC communication, multiple areas of the electronic device 1 have better NFC performance.
