[0002] With the development of technology, electronic devices with communication functions such as mobile phones are becoming more and more popular and their functions are becoming more and more powerful. Electronic devices usually include antenna systems to realize the communication functions of electronic devices. However, the communication performance of antenna systems in electronic devices in related technologies is not good enough and there is still room for improvement. Summary of the invention

[0004] A first antenna, the first antenna comprising a first radiator, a first signal source, a first matching circuit and a first adjustment circuit, the first radiator having a first feeding point, the first signal source electrically connecting the first matching circuit to the first feeding point, the first adjustment circuit electrically connecting to the first radiator or the first matching circuit, and configured to adjust the resonant frequency of the first antenna so that the first antenna supports the reception and transmission of electromagnetic wave signals within a first frequency band, wherein the first frequency band includes at least one of an LTE low frequency band and an NR low frequency band;

[0005] The control unit is used to control the first antenna in one antenna component to support the LTE low frequency band, and control the first antenna in another antenna component to support the NR low frequency band, so as to realize ENDC of the LTE low frequency band and the NR low frequency band.

[0006] In a second aspect, the present application provides an electronic device, wherein the electronic device comprises the antenna system as described in the first aspect.

[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] Reference to "embodiment" or "implementation" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment or implementation 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 an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0039] The present application provides an antenna system 10. The antenna system 10 can be applied to an electronic device 1, which includes but is not limited to a mobile phone, a mobile internet device (MID), an e-book, a portable player station (Play Station Portable, PSP) or a personal digital assistant (Personal Digital Assistant, PDA) and other electronic devices 1 with communication functions.

[0040] Please also read Figure 1 and Figure 2 , Figure 1 A schematic diagram of an antenna system provided for an embodiment of the application; Figure 2 for Figure 1 Schematic diagram of an antenna assembly in an antenna system in FIG. The antenna system 10 includes at least two antenna assemblies 100 and a control unit 200, each of the antenna assemblies 100 includes a first antenna 110. The first antenna 110 includes a first radiator 111, a first signal source 112, a first matching circuit 113, and a first adjustment circuit 114. The first radiator 111 has a first feeding point 1113, the first signal source 112 is electrically connected to the first matching circuit 113 and the first feeding point 1113, and the first adjustment circuit 114 is electrically connected to the first radiator 111 (see FIG. 1 ). Figure 2 ) or the first matching circuit 113 (see Fig. 20) is used to adjust the resonant frequency of the first antenna 110 so that the first antenna 110 supports the reception and transmission of electromagnetic wave signals in a first frequency band, wherein the first frequency band includes at least one of a Long Term Evolution (LTE) low frequency band and a New Radio (NR) low frequency band. The control unit 200 is used to control the first antenna 110 in an antenna assembly 100 to support the LTE low frequency band, and to control another antenna assembly 100 to support the NR low frequency band, so as to achieve dual connection (LTE NR Double Connect, ENDC) of the LTE low frequency band and the NR low frequency band. Figure 1 In the figure, M1 is used to indicate the first matching circuit 113 , and T1 is used to indicate the first regulating circuit 114 .

[0041] It should be noted that 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. The fact that the antenna system 10 includes a first antenna 110 does not exclude that the antenna system 10 also includes other antennas besides the first antenna 110. The so-called signal source refers to a device that generates an excitation signal. When the first antenna 110 is used to receive an electromagnetic wave signal, the first signal source 112 generates a first excitation signal, and the first excitation signal is loaded onto the first feeding point 1113 via the first matching circuit 113, so that the first radiator 111 radiates an electromagnetic wave signal.

[0042] The first radiator 111 may be a flexible printed circuit (FPC) antenna radiator, a laser direct structuring (LDS) antenna radiator, a print direct structuring (PDS) antenna radiator, or a metal branch.

[0043] In addition, since the first antenna 110 includes a first adjustment circuit 114, the first adjustment circuit 114 can adjust the resonant frequency of the first antenna 110 so that the first antenna 110 supports the transmission and reception of electromagnetic wave signals in the first frequency band range, and the first frequency band range includes at least one of the LTE low frequency band and the NR low frequency band. The first frequency band range includes at least one of the LTE low frequency band and the NR low frequency band, including the following situations: the first frequency band range includes the LTE low frequency band; or, the first frequency band includes the LTE low frequency band and the NR low frequency band; or the first frequency band includes the NR low frequency band. Therefore, the control unit 200 can control the first antenna 110 in one of the antenna assemblies 100 to support the LTE low frequency band, and the first antenna 110 in the other antenna assembly 100 to support the NR low frequency band, so as to realize the ENDC of the LTE low frequency band and the NR low frequency band. That is, two antenna components 100 can realize the LTE low-frequency band and the NR low-frequency band are ENDC. Therefore, the antenna system 10 can realize the communication functions of the 4G low-frequency band and the 5G low-frequency band by using fewer antenna components 100, while ensuring higher communication performance and using fewer antenna components 100.

[0044] When two antenna assemblies 100 implement ENDC of the LTE low frequency band and the NR low frequency band, the first antennas 110 in the two antenna assemblies 100 are both broadband antennas (600MHz-960MHz). When two antenna assemblies 100 implement ENDC of the LTE low frequency band and the NR low frequency band, the main set reception (PRX) of the LTE low frequency band and the diversity reception (DRX) of the NR low frequency band are supported by the first antenna 110 in one antenna assembly 100, and the diversity reception (DRX) of the LTE low frequency band and the main set reception (PRX) of the NR low frequency band are supported by the first antenna 110 in the other antenna assembly 100. The following is an example of supporting the B20+N28 band when two antenna assemblies 100 implement ENDC of the LTE low frequency band and the NR low frequency band. Specifically, the main reception (PRX) of B20 and the diversity reception (DRX) of N28 are supported by the first antenna 110 in one antenna assembly 100 , and the diversity reception (DRX) of B20 and the main reception (PRX) of N28 are supported by the first antenna 110 in another antenna assembly 100 .

[0045] Generally speaking, the independent networking (Non-Standalone, NSA) of the low-frequency (Lower Band, LB) band and the low-frequency band, that is, LB+LB NSA means that LB LTE+LB NR work together, which requires two signal sources (PA) to work simultaneously to transmit signals, and generally speaking, LB LTE and NR each require two antennas, PRX and DRX. Therefore, 4 antennas are required. However, the antenna size of the low-frequency band is too large, and it is difficult for a mobile phone to make 4 antennas for the low-frequency band. In this application, the main set reception (PRX) of the LTE low-frequency band and the diversity reception (DRX) of the NR low-frequency band are supported by the first antenna 110 in one antenna assembly 100, and the diversity reception (DRX) of the LTE low-frequency band and the main set reception (PRX) of the NR low-frequency band are supported by the first antenna 110 in another antenna assembly 100. Two first antennas 110 can be used to realize LB+LB NSA, thereby reducing the number of first antennas 110.

[0046] Furthermore, in this embodiment, each of the antenna components 100 further includes a second antenna 120. The second antenna 120 includes a second radiator 121, a second signal source 122, and a second matching circuit 123. The second radiator 121 is spaced apart from the first radiator 111 and coupled to each other, the second radiator 121 has a second feeding point 1213, and the second signal source 122 is electrically connected to the second matching circuit 123 to the second feeding point 1213.

[0047] exist Figure 1 In the figure, M2 is used as a second matching circuit 123. Accordingly, when the second antenna 120 is used to receive electromagnetic wave signals, the second signal source 122 generates a second excitation signal, and the second excitation signal is loaded onto the second feeding point 1213 via the second matching circuit 123, so that the second radiator 121 receives and transmits electromagnetic wave signals.

[0048] Correspondingly, the second radiator 121 may be an FPC antenna radiator, an LDS antenna radiator, a PDS antenna radiator, or a metal branch. The first radiator 111 and the second radiator 121 may be of the same type or different types.

[0049] It can be understood that in other embodiments, the antenna assembly 100 may not include the second antenna 120 .

[0050] In the antenna system 10 provided in this embodiment, the second radiator 121 and the first radiator 111 are spaced apart and coupled to each other, that is, the first radiator 111 and the second radiator 121 have the same aperture. Due to the coupling effect between the first radiator 111 and the second radiator 121, when the first antenna 110 is working, it not only uses the first radiator 111 to send and receive electromagnetic wave signals, but also uses the second radiator 121 to send and receive electromagnetic wave signals, so that the first antenna 110 can work in a wider frequency band. Similarly, when the second antenna 120 is working, it can not only use the second radiator 121 to send and receive electromagnetic wave signals, but also use the first radiator 111 to send and receive electromagnetic wave signals, so that the second antenna 120 can work in a wider frequency band. In addition, since the first antenna 110 can use not only the first radiator 111 but also the second radiator 121 to send and receive electromagnetic wave signals when working, and the second antenna 120 can use not only the second radiator 121 but also the first radiator 111 when working, the multiplexing of the radiators in the antenna system 10 is realized, and the multiplexing of space is also realized, which is conducive to reducing the size of the antenna system 10. From the above analysis, it can be seen that the size of the antenna system 10 is small, and when the antenna system 10 is applied to the electronic device 1, it is convenient to stack with other devices in the electronic device 1. In addition, since the size of the antenna system 10 is small, when the antenna system 10 is applied to the electronic device 1, more antenna systems 10 can be set in the electronic device 1.

[0051] See also Figure 3 , Figure 3 A schematic diagram of an antenna system provided for another embodiment of the application. In this embodiment, the antenna system 10 includes four antenna assemblies 100, and the control unit 200 is further used to control one of two antenna assemblies 100 of the four antenna assemblies 100 to support or both support the same LTE low frequency band, and control the other two antenna assemblies 100 of the four antenna assemblies 100 to support or both support the same NR low frequency band.

[0052] The control unit 200 is also used to control one of two antenna assemblies 100 among the four antenna assemblies 100 to support or both of them to jointly support the same LTE low frequency band, specifically including: the control unit 200 controls one of two antenna assemblies 100 among the four antenna assemblies 100 to support the LTE low frequency band; or, the control unit 200 is also used to control two of the four antenna assemblies 100 to jointly support the same LTE low frequency band.

[0053] Correspondingly, the control unit 200 controls one of the other two antenna assemblies 100 of the four antenna assemblies 100 to support or jointly support the same NR low frequency band, specifically including: the control unit 200 controls one of the two antenna assemblies 100 of the four antenna assemblies 100 to support the NR low frequency band; or, the control unit 200 is also used to control two of the four antenna assemblies 100 to jointly support the same NR low frequency band.

[0054] The control unit 200 is used to adjust the first adjustment circuit 114 in at least one first antenna 110 of the two antenna assemblies 100 to adjust the LTE low frequency band commonly supported by the two antenna assemblies 100; the control unit 200 is also used to adjust the first adjustment circuit 114 of at least one first antenna 110 of the other two antenna assemblies 100 to adjust the NR low frequency band commonly supported by the other two antenna assemblies 100, so that the antenna system 10 supports the first ENDC combination, the second ENDC combination and the third ENDC combination; the control unit 200 is also used to control the antenna system 10 to switch between the first ENDC combination, the second ENDC combination and the third ENDC combination.

[0055] In one embodiment, the first ENDC combination includes B20+N28, the second ENDC combination includes B20+N8, and the third ENDC combination includes B28+N5.

[0056] Specifically, for the convenience of description, the four antenna assemblies 100 are named antenna assembly 100a, antenna assembly 100b, antenna assembly 100c and antenna assembly 100d. The first antenna 110 in the antenna assembly 100a supports the first frequency band (a), the first antenna 110 in the antenna assembly 100b supports the first frequency band (b), the first antenna 110 in the antenna assembly 100c supports the first frequency band (c), and the first antenna 110 in the antenna assembly 100d supports the first frequency band (d). The combined bandwidth formed by the first frequency band (a), the first frequency band (b), the first frequency band (c) and the first frequency band (d) is greater than or equal to 350 MHz. Optionally, the first frequency band (a), the first frequency band (b), the first frequency band (c) and the first frequency band (d) each support a bandwidth of 80 to 100M, and the control unit 200 adjusts the first frequency band (a), the first frequency band (b), the first frequency band (c) and the first frequency band (d) so that there is no overlap or less overlap, so that in the same time period, the sum of the bandwidths of the first frequency band (a), the first frequency band (b), the first frequency band (c) and the first frequency band (d) is greater than or equal to 350MHz, thereby simultaneously supporting low-frequency signals with a bandwidth of at least 350MHz. Of course, in other embodiments, the control unit 200 adjusts the first adjustment circuit 114 so that the resonant frequency point of the electromagnetic wave signal received and transmitted by the first antenna 110 in each antenna assembly 100 is offset, thereby making the bandwidth of the electromagnetic wave signal received and transmitted by each antenna assembly 100 in different time periods greater than or equal to 350MHz.

[0057] In one embodiment, the combined frequency band formed by the first frequency band (a), the first frequency band (b), the first frequency band (c) and the first frequency band (d) covers 617 to 960 MHz. The antenna system 10 provided in the embodiment of the present application is configured by setting each first antenna 110 in the four antenna assemblies 100 so that the combined bandwidth formed by the first frequency band (a), the first frequency band (b), the first frequency band (c) and the first frequency band (d) is greater than or equal to 350 MHz. In this way, the antenna system 10 can cover the application frequency band of 617 MHz to 960 MHz, so that the electronic device 1 covers the combined frequency band of 617 MHz to 960 MHz, thereby improving the communication performance of the electronic device 1 in the low frequency band.

[0058] The combined frequency band formed by the first frequency band (a), the first frequency band (b), the first frequency band (c) and the first frequency band (d) covers the first application frequency band and the second application frequency band. Among them, the first application frequency band includes the 4G frequency band, and the second application frequency band includes the 5G frequency band. For example, the first application frequency band includes at least one of B20 and B28, and the second application frequency band includes at least one of N28, N8 and N5. In this way, the electronic device 1 can simultaneously support 4G communication and 5G communication, and realize ultra-wideband carrier aggregation (Carrier Aggregation, CA) and the dual connection (LTE NR Double Connect, ENDC) combination of 4G wireless access network and 5G-NR.

[0059] Since the antenna system 10 has a relatively wide bandwidth, for example, greater than 350 MHz, the antenna system 10 can support the B20+N28 frequency band. In addition, the antenna system 10 also supports the B28+N5 frequency band, the B20+N8 frequency band, etc., so that the electronic device 1 can support the frequency band range planned by each operator, thereby improving the applicability of the electronic device 1 to different planned frequency bands.

[0060] In a possible implementation, the first antenna 110 in at least two of the antenna assemblies 100 among the antenna assembly 100a, the antenna assembly 100b, the antenna assembly 100c, and the antenna assembly 100d is used to support the first application frequency band or the second application frequency band, and the frequency band ranges received and transmitted by the first antenna 110 in at least two of the antenna assemblies 100 supporting the first application frequency band or the second application frequency band in the same time period are partially overlapping or non-overlapping.

[0061] Specifically, when the bandwidth of the first application frequency band is relatively large or in order to improve the receiving and transmitting efficiency of the first application frequency band, two, three or four of the antenna component 100a, the antenna component 100b, the antenna component 100c and the antenna component 100d can be adjusted to support the first application frequency band, and the antenna component 100a, the antenna component 100b, the antenna component 100c and the antenna component 100d can be adjusted to support the second application frequency band.

[0062] Furthermore, the first frequency band (a), the first frequency band (b), the first frequency band (c) and the first frequency band (d) each support a bandwidth of 80 to 100M, and the first frequency band (a), the first frequency band (b), the first frequency band (c) and the first frequency band (d) are adjusted so that there is no overlap or little overlap between each other in the same time period, so that the first antennas 110 in two antenna assemblies 100 can support the first application frequency band, and the first antennas 110 in the other two antenna assemblies 100 can support the second application frequency band. In this way, the first application frequency band and the second application frequency band can be supported at the same time, and the two application frequency bands can be supported by different antenna assemblies 100 to reduce the mutual influence between the first application frequency band and the second application frequency band.

[0063] When the electronic device 1 needs to work in the first application frequency band, the shielding condition of the antenna system 10 can be determined according to the holding condition of the electronic device 1, and two antenna components 100 supporting the first application frequency band can be flexibly selected according to the shielding condition of the antenna system 10. For example, when the antenna components 100a and 100c among the antenna components 100a, 100b, 100c and 100d are shielded, the control unit 200 selects the antenna components 100b and 100d to support the first application frequency band. It can be seen that the control unit 200 can control the frequency band supported by each antenna component 100 among the antenna components 100a, 100b, 100c and 100d, and can effectively deal with the problem of relatively weak signals caused by the holding scenario of the electronic device 1. The control unit 200 may also control the antenna assembly 100 which is far from the human head to operate or reduce the power of the antenna assembly 100 when the human head is close to the electronic device 1 to improve the safety of the electronic device 1.

[0064] When the antenna system 10 supports the ENDC combination, the control unit 200 controls any two of the antenna components 100a, the antenna component 100b, the antenna component 100c, and the antenna component 100d to support the LTE frequency band, and controls the other two antenna components to support the NR frequency band to achieve ENDC. The following is an introduction taking the first ENDC combination including B20+N28 as an example. In other words, the antenna system 10 can support an ENDC combination of B20+N28 frequency bands. The control unit 200 controls any two of the antenna components 100a, the antenna component 100b, the antenna component 100c, and the antenna component 100d to support the B20 frequency band, and controls the other two antenna components to support the N28 frequency band. For example, in one embodiment, the control unit 200 controls the antenna component 100a and the antenna component 100c to jointly support the B20 frequency band, and controls the antenna component 100b and the antenna component 100d to jointly support the N28 frequency band. In other embodiments, the control unit 200 controls the antenna assembly 100b and the antenna assembly 100c to jointly support the N28 frequency band, and controls the antenna assembly 100a and the antenna assembly 100d to jointly support the N28 frequency band. It should be noted that the control unit 200 can select two of the four antenna assemblies to jointly support the LTE frequency band and the other two antenna assemblies to jointly support the NR frequency band according to the specific use of the electronic device 1 (such as the scene of being held), and the above examples should not be understood as limitations on this application.

[0065] See also Figure 4 , Figure 4 A schematic diagram of an antenna assembly provided for applying for another embodiment. In the antenna assembly 100 described in this embodiment, the first radiator 111 has a first free end 1112 and a first grounding end 1111 that are arranged opposite to each other. The first grounding end 1111 is grounded. The first radiator 111 also includes a first connection point 1114. The first feeding point 1113 and the first connection point 1114 are arranged at intervals between the first free end 1112 and the first grounding end 1111, and when the first regulating circuit 114 is electrically connected to the first radiator 111, the first regulating circuit 114 is electrically connected to the first connection point 1114. In this embodiment, the first connection point 1114 is located between the first free end 1112 and the first feeding point 1113.

[0066] The second radiator 121 also includes a second grounding end 1211 and a second free end 1212. The second grounding end 1211 is grounded, the second free end 1212 is spaced apart from the first reset body 111 (in this embodiment, the second free end 1212 is spaced apart from the first free end 1112), and the second feeding point 1213 is located between the second grounding end 1211 and the second free end 1212.

[0067] See also Figure 5 , Figure 5 A schematic diagram of an antenna assembly provided for applying for another embodiment. The first radiator 111 has a first free end 1112 and a first grounding end 1111 disposed opposite to each other. The first grounding end 1111 is grounded. The first radiator 111 also includes a first connection point 1114. The first feeding point 1113 and the first connection point 1114 are spaced apart between the first free end 1112 and the first grounding end 1111, and when the first regulating circuit 114 is electrically connected to the first radiator 111, the first regulating circuit 114 is electrically connected to the first connection point 1114. In this embodiment, the first connection point 1114 is located between the first grounding end 1111 and the first feeding point 1113.

[0068] When the first connection point 1114 is located between the first free end 1112 and the first feeding point 1113, the influence of the electromagnetic wave signal supported by the first radiator 111 (corresponding to the electromagnetic wave signal supported by the second resonant mode described later) on the electromagnetic wave signals of other frequency bands supported and received by the antenna assembly 100 can be reduced. It can be understood that the first connection point 1114 can also be located between the first ground end 1111 and the first feeding point 1113, as long as the first adjustment circuit 114 is electrically connected to the first connection point 1114 so that the first antenna 110 receives and transmits electromagnetic wave signals within the first frequency band. In addition, it should be noted that the position of the first connection point 1114 on the first radiator 111 is also related to the range of electromagnetic wave signals supported and received by the first antenna 110.

[0069] In this embodiment, the antenna assembly 100 has a first resonance mode, a second resonance mode, a third resonance mode, and a fourth resonance mode to cover the transmission and reception of electromagnetic wave signals within the second frequency band and the third frequency band.

[0070] At least one of the first resonance mode, the second resonance mode, the third resonance mode and the fourth resonance mode is generated by a higher-order mode of the first adjustment circuit 114 and the first radiator 111 from the first connection point 1114 to the first free end 1112 .

[0071] Specifically, when one end of the first adjustment circuit 114 is grounded and the other end is connected to the first connection point 1114, the fundamental mode from the second ground end 1211 of the second radiator 121 to the second free end 1213 generates the first resonance mode, the fundamental mode from the first adjustment circuit 114 and the first radiator 111 from the first connection point 1114 to the first free end 1112 generates the second resonance mode, the fundamental mode from the second signal source 122 and the second feeding point 1213 to the second free end 1212 of the second radiator 121 generates the third resonance mode, and the higher-order mode from the first adjustment circuit 114 and the first radiator 111 from the first connection point 1114 to the first free end 1112 generates the fourth resonance mode.

[0072] See also Figure 6 , Figure 6 Schematic diagram of an antenna assembly provided in one embodiment of the present application. The antenna assembly 100 includes a first antenna 110 and a second antenna 120. The first antenna 110 includes a first radiator 111, a first signal source 112, and a first matching circuit 113. The first radiator 111 has a first feeding point 1113, and the first signal source 112 is electrically connected to the first matching circuit 113 to the first feeding point 1113. The second antenna 120 includes a second radiator 121, a third radiator 125, a second signal source 122, and a second matching circuit 123.

[0073] In addition, the second radiator 121 and the third radiator 125 in the second antenna 120 in the antenna assembly 100 provided in this embodiment share the second matching circuit 123, so that when the second antenna 120 transmits and receives electromagnetic wave signals, it can not only use the second radiator 121 to transmit and receive electromagnetic wave signals, but also use the third radiator 125 to transmit and receive electromagnetic wave signals. Therefore, the second antenna 120 can support the transmission and reception of electromagnetic wave signals in more frequency bands.

The application bands included in the MHB band include B3, B1, B41, and B7. The application bands included in the UHB band include N77, N78, and N79, so that the electronic device 1 can support the frequency band range planned by each operator, thereby improving the applicability of the electronic device 1 to different planned frequency bands.

[0076] It can be understood that in other implementations, the first antenna 110 and the second antenna 120 also support the transmission and reception of electromagnetic wave signals in other frequency bands. In other implementations, the first antenna 110 and the second antenna 120 support electromagnetic wave signals in other frequency bands. The following is a detailed description of the situation.

[0078] In the following embodiments, an example is given in which the first antenna 110 is used to transmit and receive electromagnetic wave signals within a first frequency band, and the second antenna 120 is used to transmit and receive electromagnetic wave signals within a second frequency band and a third frequency band.

[0079] In this embodiment, the antenna assembly 100 has a first resonance mode, a second resonance mode, a third resonance mode, and a fourth resonance mode to cover the transmission and reception of electromagnetic wave signals within the second frequency band and the third frequency band.

[0080] At least one of the first resonance mode, the second resonance mode, the third resonance mode and the fourth resonance mode is generated by the third radiator. Each resonance mode will be introduced later in conjunction with a simulation schematic diagram of the antenna assembly 100 .

[0082] The first adjustment circuit 114 realizes low impedance to the ground of electromagnetic wave signals in the second frequency band and the third frequency band, and the radiation of the first radiator 111 from the connection point where the first adjustment circuit 114 is connected to the first radiator 111 to the ground end (first ground end 1111) of the first radiator 111 is equivalent to zero.

[0083] In this embodiment, the first radiator 111 further includes a first grounding terminal 1111, a first free terminal 1112, and a first connection point 1114. The first grounding terminal 1111 is grounded, the first connection point 1114 and the first feeding point 1113 are spaced apart, and both are disposed between the first free terminal 1112 and the first grounding terminal 1111. One end of the first regulating circuit 114 is grounded, and the other end is electrically connected to the first connection point 1114. The second radiator 121 further includes a second grounding terminal 1211 and a second free terminal 1212, the second grounding terminal 1211 is grounded, the second free terminal 1212 and the first free terminal 1112 are spaced apart, and the second feeding point 1213 is located between the second grounding terminal 1211 and the second free terminal 1212.

[0084] In this embodiment, the first connection point 1114 is disposed between the first feeding point 1113 and the first free end 1112 .

[0085] Please refer to the figure Fig.10 , Fig.10 for Figure 6The schematic diagram of the simulation of some S parameters of the antenna assembly shown. In the schematic diagram of this embodiment, the horizontal axis is the frequency in GHz, and the vertical axis is the S parameter in dB. The second ground end 1211 of the second radiator 121 to the second free end 1212 generates the first resonance mode (marked as mode 1 in the figure), the first adjustment circuit 114 and the first radiator 111 generate the second resonance mode (marked as mode 2 in the figure) from the first connection point 1114 to the first free end 1112, the second signal source 122 and the second feeding point 1213 of the second radiator 121 to the second free end 1212 generate the third resonance mode (marked as mode 3 in the figure), and the third radiator 125 generates the fourth resonance mode (marked as mode 4 in the figure).

[0086] It can be seen from the simulation diagram of this embodiment that the first resonant mode, the second resonant mode, the third resonant mode and the fourth resonant mode in the antenna assembly 100 can cover the transmission and reception of electromagnetic wave signals in the MHB frequency band and the UHB frequency band, that is, the transmission and reception of electromagnetic wave signals in the 1000MHz-6000MHz frequency band is realized.

[0087] In one embodiment, the first resonant mode is the fundamental mode or higher-order mode of the second antenna 120 operating at the second ground end 1211 of the second radiator 121 to the second free end 1212, the second resonant mode is the fundamental mode or higher-order mode of the first adjustment circuit 114 and the first radiator 111 from the first connection point 1114 to the first free end 1112, the third resonant mode is the fundamental mode or higher-order mode of the second antenna 120 operating at the second signal source 122 and the second feeding point 1213 of the second radiator 121 to the second free end 1212, and the fourth resonant mode is the fundamental mode or higher-order mode of the second antenna 120 operating at the third radiator 125.

[0089] The first resonance mode is a quarter-wavelength fundamental mode in which the second antenna 120 operates from the second ground end 1211 to the second free end 1212 of the second radiator 121. It can be understood that when the first resonance mode is a fundamental mode in which the second antenna 120 operates from the second ground end 1211 to the second free end 1212 of the second radiator 121, the first resonance mode has a higher transmit and receive power.

[0090] Similarly, the second resonance mode is when the first antenna 110 operates in the fundamental mode of the first adjustment circuit 114 and the first radiator 111 from the first connection point 1114 to the first free end 1112, and the second resonance mode has a higher transmit and receive power.

The antenna assembly 100 and Fig.19 The structures of the antenna assemblies 100 provided are substantially the same, except that Fig.14In the corresponding embodiment, the first connection point 1114 is located between the first feeding point 1113 and the first free end 1112. In this embodiment, the first connection point 1114 is located between the first feeding point 1113 and the first grounding end 1111. For the remaining structures of the antenna assembly 100 in this embodiment, please refer to Fig.14 The description of its related implementation methods will not be repeated here.

[0114] It can be seen from the above embodiments that the first adjustment circuit 114 in the first antenna 110 includes the following manner: one end of the first adjustment circuit 114 is electrically connected to the first connection point 1114, and the other end is grounded; or, one end of the first adjustment circuit 114 is electrically connected to the first matching circuit 113, and the other end is grounded. When one end of the first adjustment circuit 114 is electrically connected to the first connection point 1114 and grounded, and the other end is grounded, it includes the following situation: the first connection point 1114 is located between the first feeding point 1113 and the first free end 1112; or, the first connection point 1114 is located between the first feeding point 1113 and the first grounding end 1111. The first antenna 110 may include the fourth radiator 115 or not. When the first antenna 110 includes the fourth radiator 115, the fourth radiator 115 is electrically connected to the first matching circuit 113.

[0115] When the first connection point 1114 is located between the first feeding point 1113 and the first free end 1112, the influence of the electromagnetic wave signal supported by the second resonance mode generated by the first radiator 111 on the electromagnetic wave signals of other frequency bands supported by the antenna assembly 100 can be reduced. It can be understood that the first connection point 1114 can also be located between the first feeding point 1113 and the first grounding end 1111, as long as the first adjustment circuit 114 can be electrically connected to the first radiator 111.

[0116] Correspondingly, the second adjustment circuit 124 in the second antenna 120 includes the following mode: one end of the second adjustment circuit 124 is electrically connected to the second connection point 1214, and the other end is grounded; or, one end of the second adjustment circuit 124 is electrically connected to the second matching circuit 123, and the other end is grounded. When one end of the second adjustment circuit 124 is electrically connected to the second connection point 1214, and the other end is grounded, it includes the following situations: the second connection point 1214 is located between the second feeding point 1213 and the second free end 1212; or, the second connection point 1214 is located between the second feeding point 1213 and the second grounding end 1211.

[0117] When the second connection point 1214 is located between the second feeding point 1213 and the second free end 1212, the influence of the electromagnetic wave signal generated by the second radiator 121 on the electromagnetic wave signals of other frequency bands supported by the antenna assembly 100 can be reduced. It can be understood that the second connection point 1214 can also be located between the second feeding point 1213 and the second grounding end 1211, as long as the second adjustment circuit 124 can be electrically connected to the second radiator 121.

[0120] It can be understood that for the antenna assembly 100, the gap between the radiator of the first antenna 110 and the radiator of the second antenna 120 in the antenna assembly 100 satisfies d: 0.5mm≤d≤1.5mm. This ensures that the first radiator 111 and the second radiator 121 have a better coupling effect. Figure 2 The antenna assembly 100 shown is used as an example for illustration, but it should not be understood as a limitation to the present application.

[0127] The so-called top 1 a refers to the portion of the electronic device 1 that is located on the upper side when the electronic device 1 is in use, and the bottom 1 b is the area located below the electronic device 1 opposite to the top 1 a .

[0128] The electronic device 1 in this embodiment includes a first side 11, a second side 12, a third side 13, and a fourth side 14 connected in sequence from end to end. The first side 11 and the third side 13 are short sides of the electronic device 1, and the second side 12 and the fourth side 14 are long sides of the electronic device 1.

The connection between the first side 11 and the second side 12, the connection between the second side 12 and the third side 13, the connection between the third side 13 and the fourth side 14, and the connection between the fourth side 14 and the first side 11 all form corners of the electronic device 1.
