[0063] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meaning as commonly understood by one of ordinary skill in the art.

[0064] In order to make the purpose, technical scheme and advantages of the present application clearer, the embodiments of the present application will be described in further detail below with reference to the drawings.

[0065] In one aspect, in combination Figure 1 As shown in the embodiment, an antenna assembly is provided, which comprises a first radiating branch 1, a second radiating branch 2 and a fusion branch 4.

[0066] The first radiating branch 1 comprises a first end 101 and a second end 102, and the second radiating branch 2 comprises a third end 201 and a fourth end 202. A gap structure 3 is arranged between the first end 101 and the third end 201. The second end 102 and the fourth end 202 extend in directions away from the gap structure 3 and are respectively grounded.

[0067] The first radiating branch 1 is provided with a first upper frame point 11 and a second upper frame point 12. The first upper frame point 11 is used for feeding connection of the first radiating branch 1. The second radiating branch 2 is provided with a third upper frame point 21 and a fourth upper frame point 22. The third upper frame point 21 is used for feeding connection of the second radiating branch 2.

[0068] The fusion branch 4 is located on one side of the first radiating branch 1 and the second radiating branch 2. An end of the fusion branch 4 close to the first radiating branch 1 is electrically connected to the second upper frame point 12, and an end of the fusion branch 4 close to the second radiating branch 2 is electrically connected to the fourth upper frame point 22.

[0069] The fusion branch 4 is used for adjusting the phase difference between the first radiating branch 1 and the second radiating branch 2.

[0070] The antenna assembly of the embodiment has the first radiating branch 1, the second radiating branch 2 and the fusion branch 4. The first radiating branch 1 and the second radiating branch 2 are arranged head to head. In addition to the first upper frame point 11 for feeding on the first radiating branch 1, the second upper frame point 12 corresponding to the fusion branch 4 is also arranged. In addition to the third upper frame point 21 for feeding on the second radiating branch 2, the fourth upper frame point 22 corresponding to the fusion branch 4 is also arranged. Therefore, the fusion branch 4 is electrically connected to the first radiating branch 1 and the second radiating branch 2 through the second upper frame point 12 and the fourth upper frame point 22 respectively. When the antenna assembly works, reverse current will inevitably appear on the first radiating branch 1 or the second radiating branch 2, which will interfere with the normal working performance of the antenna assembly. At this time, the fusion branch 4 can adjust the phase difference between the first radiating branch 1 and the second radiating branch 2, so as to eliminate the reverse current to the greatest extent, and thus achieve the purpose of improving the working performance of the antenna assembly.

[0071] In some possible implementations, the first radiating branch 1 and the second radiating branch 2 are respectively arranged on a metal middle frame of an electronic device, forming a kind of frame antenna.

[0072] The reverse current of the frame antenna refers to the reverse current phenomenon that may occur in the antenna feeding point or the antenna structure due to the radiation characteristics and current distribution of the antenna.

[0073] In the art, the phase of an antenna refers to the relative phase difference between the rate of change of the electric field and the magnetic field in the radio waves emitted by the antenna. In a radio communication system, the phase is an especially important parameter, which relates to the transmission quality of the signal and the utilization rate of the bandwidth.

[0074] In the embodiment, by adjusting the phase difference between the first radiating branch 1 and the second radiating branch 2, the current mode in the first radiating branch 1 and the second radiating branch 2 can be changed, so that the reverse current of the first radiating branch 1 and the second radiating branch 2 can be eliminated, thereby achieving the purpose of improving the working performance of the antenna assembly at different frequency bands.

[0075] In combination Figure 1 As shown in the figure, in some embodiments, the second upper frame point 12 is located between the first end 101 and the second end 102, and is arranged close to the first end 101. The fourth upper frame point 22 is located between the third end 201 and the fourth end 202, and is arranged close to the third end 201.

[0076] Through the above arrangement, the fusion branch 4 can be connected at the position of the first radiating branch 1 close to the first end 101 and the position of the second radiating branch 2 close to the third end 201 respectively, and the connection position of the fusion branch 4 can more significantly adjust the current mode of the first radiating branch 1 or the second radiating branch 2, thereby achieving the effect of improving the working performance of the antenna assembly.

[0077] On the first radiating branch 1 and the second radiating branch 2, since the first end 101 and the second end 102 are arranged on the two sides of the break structure 3 respectively, the voltage at this position is relatively high, and the current density is small. If the fusion branch 4 is connected at this position, it has little effect on the current mode on the first radiating branch 1 and the second radiating branch 2, and cannot achieve the effect of improving the working performance of the antenna assembly.

[0078] And for the second end 102 of the first radiating branch 1 and the fourth end 202 of the second radiating branch 2, which are the grounding regions of the first radiating branch 1 and the second radiating branch 2 respectively, the current density is most concentrated. If the fusion branch 4 is connected at this position, it will not only affect the reverse current, but also interfere with the forward current, which not only cannot improve the working performance of the antenna assembly, but also will reduce the working performance of the antenna assembly.

[0079] In combination Figure 2 As shown in the figure, in some embodiments, the length of the first radiating branch 1 is L1, and the distance between the second upper frame point 12 and the first end 101 is L11, wherein the value range of L11 / L1 is 0.2-0.3.

[0080] When the length L1 of the first radiating branch 1, the spacing L11 between the second upper frame point 12 and the first end 101 satisfy the above ratio range, the fusion branch 4 is connected with the second upper frame point 12, the current distribution characteristics on the first radiating branch 1 can be considered, and the reverse current on the first radiating branch 1 can be eliminated when the antenna assembly works, thereby improving the working performance of the first radiating branch 1.

[0081] In some possible implementation manners, the ratio L11 / L1 of the length L1 of the first radiating branch 1 and the spacing L11 between the second upper frame point 12 and the first end 101 is, for example, 0.2, 0.21, 0.22, 0.23, 0.24, 0.25, 0.26, 0.27, 0.28, 0.29, 0.3, and the like.

[0082] For example, the ratio L11 / L1 is 0.25.

[0083] In combination Figure 2 As shown in the drawings, in some embodiments, the length of the second radiating branch 2 is L2, and the spacing between the fourth upper frame point 22 and the third end 201 is L21, wherein the ratio L21 / L2 is in the range of 0.2-0.3.

[0084] When the length L2 of the second radiating branch 2 and the spacing L21 between the fourth upper frame point 22 and the third end 201 satisfy the above ratio range, the fusion branch 4 is connected with the fourth upper frame point 22, the current distribution characteristics on the second radiating branch 2 can be considered, and the reverse current on the second radiating branch 2 can be eliminated when the antenna assembly works, thereby improving the working performance of the second radiating branch 2.

[0085] In some possible implementation manners, the ratio L21 / L2 of the length L2 of the second radiating branch 2 and the spacing L21 between the fourth upper frame point 22 and the third end 201 is, for example, 0.2, 0.21, 0.22, 0.23, 0.24, 0.25, 0.26, 0.27, 0.28, 0.29, 0.3, and the like.

[0086] For example, the ratio L21 / L2 is 0.25.

[0087] In combination Figure 3 As shown in the drawings, in some embodiments, the antenna assembly further includes a first adjusting circuit 5.

[0088] The first adjusting circuit 5 includes a first switching element 51 and at least one first capacitive and inductive element 52, and the first switching element 51 and the at least one first capacitive and inductive element 52 are arranged in series between the second upper frame point 12 and the fusion branch 4.

[0089] Through the above arrangement, the fusion branch 4 can be electrically connected with the second upper frame point 12 of the first radiation branch 1 by the first switching element 51 and the at least one first capacitive and inductive element, wherein the first switching element 51 can realize the conduction and disconnection of the fusion branch 4 and the first radiation branch 1. When the number of the first capacitive and inductive elements 52 is multiple, the first switching element 51 can not only be used to realize the conduction and disconnection of the fusion branch 4 and the first radiation branch 1, but also realize the switching of the first capacitive and inductive elements 52 connected between the fusion branch 4 and the first radiation branch 1, so that the first adjustment circuit 5 has different circuit characteristics, and thus the fusion branch 4 can switch different circuit characteristics of the first adjustment circuit 5 in different frequency band scenarios, and can cope with the reverse current of the first radiation branch 1 in different frequency band scenarios.

[0090] In some possible implementations, the first capacitive and inductive element 52 can be a capacitive element or an inductive element.

[0091] In some embodiments, the number of the first capacitive and inductive elements 52 is, for example, one, two, three, etc. When the number of the first capacitive and inductive elements 52 is multiple, the multiple first capacitive and inductive elements 52 are arranged in parallel, and each branch where each first capacitive and inductive element 52 is located can be respectively and independently controlled to be connected or disconnected by the first switching element 51.

[0092] In combination Figure 4 As shown, in some embodiments, the first capacitive and inductive element 52 includes a first inductive element 521 and a first capacitive element 522.

[0093] One end of the first switching element 51 is connected with the second upper frame point 12, and the other end of the first switching element 51 is respectively connected with one end of the first inductive element 521 and one end of the first capacitive element 522. The other end of the first inductive element 521 and the other end of the first capacitive element 522 are respectively connected with the fusion branch 4.

[0094] The first switching element 51 is used to control the second upper frame point 12 and the fusion branch 4 to be electrically connected through the first inductive element 521 and / or the first capacitive element 522.

[0095] Through the above arrangement, the first adjustment circuit 5 can control the conduction and disconnection of the branch where the first inductive element 521 or the first capacitive element 522 is located by the first switching element 51, so that the first adjustment circuit 5 has different circuit characteristics and can eliminate the reverse current of the first radiation branch 1 in different frequency bands.

[0096] In combination Figure 3 As shown, in some embodiments, the antenna assembly further includes a second adjustment circuit 6.

[0097] The second adjusting circuit 6 comprises a second switching element 61 and at least one second capacitive-inductive element 62, which are arranged in series between the fourth upper frame point 22 and the fusion branch 4.

[0098] Through the above arrangement, the fusion branch 4 can be electrically connected with the fourth upper frame point 22 of the second radiation branch 2 by the second switching element 61 and the at least one second capacitive-inductive element 62, wherein the second switching element 61 can realize the conduction and disconnection of the fusion branch 4 and the second radiation branch 2. When the number of the second capacitive-inductive elements 62 is multiple, the second switching element 61 can not only be used to realize the conduction and disconnection of the fusion branch 4 and the second radiation branch 2, but also realize the switching of the second capacitive-inductive elements 62 connected between the fusion branch 4 and the second radiation branch 2, so that the second adjusting circuit 6 has different circuit characteristics, and thus the fusion branch 4 can switch different circuit characteristics of the second adjusting circuit 6 in different frequency band scenarios, and can cope with the reverse current of the second radiation branch 2 in different frequency band scenarios.

[0099] In some possible implementations, the second capacitive-inductive element 62 can be a capacitive element or an inductive element.

[0100] In some embodiments, the number of the second capacitive-inductive elements 62 is, for example, one, two, three, etc. When the number of the second capacitive-inductive elements 62 is multiple, the multiple second capacitive-inductive elements 62 are arranged in parallel, and each branch where the second capacitive-inductive element 62 is located can be controlled to be connected or disconnected by the second switching element 61 respectively and independently.

[0101] In combination Figure 4 As shown, in some embodiments, the second capacitive-inductive element 62 comprises a second capacitive element 621.

[0102] One end of the second switching element 61 is connected to the fourth upper frame point 22, the other end of the second switching element 61 is electrically connected to one end of the second capacitive element 621, and the other end of the second capacitive element 621 is electrically connected to the fusion branch 4.

[0103] Through the above arrangement, the second adjusting circuit 6 can control the conduction and disconnection of the second capacitive element 621 by the second switching element 61, so that the second adjusting circuit 6 can be capacitively conductive or disconnected with the second radiation branch 2, and the reverse current of the second radiation branch 2 can be eliminated in different frequency bands.

[0104] In some embodiments, the fusion branch 4 is at least one of an LDS branch and an FPC branch.

[0105] LDS stubs are circuit patterns rapidly formed on the surface of a device by controlling the movement of a laser according to the trajectory of a conductive pattern. In other words, they are metal stubs formed by directly depositing metal onto the surface of a device using laser technology.

[0106] FPC stubs, or flexible printed circuit board (FPC) antennas, are devices that use special materials and processes to print antennas onto flexible circuit boards. These antennas combine the advantages of flexible circuitry and antenna technology, featuring thinness, flexibility, and bendability, making them suitable for various complex and compact equipment spaces. The advantages of FPC antennas include their high flexibility and adaptability, enabling them to meet the needs of different equipment and environments.

[0107] In some embodiments, the first upper frame point 11 is used to feed the first radiating stub 1 in the LB band, and the third upper frame point 21 is used to feed the second radiating stub 2 in the MHB band.

[0108] The LB band is the low-frequency band, and the MHB band is the medium-high frequency band.

[0109] The frequency range of the LB band is between 30MHz and 1GHz, including but not limited to the B28 band (700MHz), the B5 band (850MHz) and the B8 band (900MHz).

[0110] The MHB band is between 1 GHz and 3 GHz, including but not limited to the B3 band (1800 MHz), B1 band (2100 MHz), B40 band (2 MHz) and B41 band (2500 MHz).

[0111] Figure 5 This is a current distribution diagram of the antenna assembly in the B3 frequency band provided in the embodiments of this application; Figure 6 This is a current distribution diagram of the antenna assembly provided in the embodiment of this application in the B41 frequency band.

[0112] Combination Figure 5 and Figure 6 It can be seen that the fused stub 4 eliminates the reverse current on the first radiating stub 1 and the second radiating stub 2 in the B3 and B41 bands. The current direction on the fused stub 4 is the same as the forward current direction on the first radiating stub 1 and the second radiating stub 2, and the working performance of the antenna assembly is improved by using the same current direction.

[0113] Figure 7is a return loss test effect diagram of the antenna assembly provided by the embodiment of the present application; Figure 8 is a radiation efficiency test effect diagram of the antenna assembly provided by the embodiment of the present application.

[0114] In combination Figure 7 It can be seen that the return loss of the antenna assembly provided by the embodiment of the present application can cover the corresponding frequency band in B1, B3, B32 and B40 frequency bands, and the working coverage of the corresponding frequency band can be realized. In combination Figure 8 It can be seen that the radiation efficiency of the antenna assembly provided by the embodiment of the present application is above -5dB in the frequency range of 1.4-2.7GHz, and the radiation requirement of all frequency bands in the frequency range can be basically realized.
