[0030] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0031] In current electronic devices, the narrow bandwidth of antennas limits the amount of data that can be transmitted by the electronic devices, thus failing to meet user needs.

[0032] In view of the above technical problems, the present disclosure provides an antenna assembly 10 for an electronic device. The antenna assembly 10 has multiple conductive loops 13 coupled between two antenna feed ends (e.g., a first antenna feed end 11 and a second antenna feed end 12 with opposite polarities) to generate different radiation paths and have different resonant frequency points / grounding points. This allows the antenna assembly 10 to operate effectively over a wide frequency range, thereby broadening the operating bandwidth of the antenna assembly 10 and meeting user requirements, and meeting relevant certification specifications. In addition, as electronic devices 100 pursue thinness and lightness, the space within the electronic device 100 for arranging the antenna is very limited. In the antenna assembly 10 of the present disclosure, at least a portion of the conductive loop 13 is formed by a conductive side frame 20 of the electronic device 100 (e.g., a side frame made of a metal material in the electronic device 100). In this way, when the electronic device 100 pursues thinness and lightness and limited installation space, the metal side frame of the electronic device 100 can be used to form a portion of the antenna assembly 10, thereby reducing the manufacturing cost of the antenna assembly 10, reducing the volume of the antenna assembly 10, and simplifying the structure of the antenna assembly 10.

[0033] First aspect

[0034] The present disclosure provides an antenna assembly 10 in an electronic device. Figures 1 to 3 and Figure 5 As shown, the antenna assembly 10 may include: a first antenna feed end 11 and a second antenna feed end 12, the polarities of the first antenna feed end 11 and the second antenna feed end 12 being opposite; at least two conductive rings 13 coupled between the first antenna feed end 11 and the second antenna feed end 12, and at least a portion of each conductive ring 13 is formed by a conductive side frame 20 of the electronic device 100.

[0035] The antenna assembly 10 in the electronic device can be assembled in the electronic device 100 (such as a mobile phone, a tablet computer, etc.) so that the electronic device 100 can send and receive wireless signals; a circle of side frames of the electronic device 100 forms the outer shell of the electronic device 100 in the thickness direction, and part or all of the segments in the circle of side frames are made of conductive materials such as metal to form a conductive side frame 20.

[0036] The polarities of the first antenna feed terminal 11 and the second antenna feed terminal 12 are opposite, that is, the first antenna feed terminal 11 is the positive terminal and the second antenna feed terminal 12 is the negative terminal, or the first antenna feed terminal 11 is the negative terminal and the second antenna feed terminal 12 is the positive terminal. At least two conductive loops 13 are coupled between the first antenna feed terminal 11 and the second antenna feed terminal 12, and the polarities of the first antenna feed terminal 11 and the second antenna feed terminal 12 are opposite. In this way, the first antenna feed terminal 11, any conductive loop 13, and the second antenna feed terminal 12 form a closed loop. At least a portion of each conductive loop 13 is formed by the conductive side frame 20 of the electronic device 100. In other words, part or all of each conductive loop 13 is the conductive side frame 20.

[0037] In one example, an electronic device 100 is a tablet computer, and the tablet computer is provided with the antenna assembly 10 of the electronic device described above, see Figure 1 and Figure 2As shown, the antenna assembly 10 in the electronic device may include: a first antenna feed end 11 and a second antenna feed end 12, wherein the first antenna feed end 11 is a positive terminal and the second antenna feed end 12 is a negative terminal; three conductive rings 13 (respectively, a first conductive ring 131, a second conductive ring 132, and a third conductive ring 133), each of which is rectangular and has different lengths and the same width, coupled between the first antenna feed end 11 and the second antenna feed end 12, and a long side of each conductive ring 13 is formed by the conductive side frame 20 of the electronic device 100. When the antenna assembly 10 is in a transmitting mode, the high-frequency current emitted by the transmitting device in the electronic device 100 is introduced into the antenna assembly 10, so that the conductive ring 13 can generate and radiate electromagnetic waves, and other receiving devices can receive the radiation to obtain the information carried by the radiation, thereby achieving signal transmission; when the antenna assembly 10 is in a receiving mode, the conductive ring 13 converts the collected electromagnetic waves into current and transmits it to the receiving device in the electronic device 100 for processing, thereby achieving signal reception.

[0038] In one example, an electronic device 100 is a tablet computer, and the tablet computer is provided with the antenna assembly 10 of the electronic device described above, see Figure 3 As shown, the antenna assembly 10 in the electronic device may include: a first antenna feed end 11 and a second antenna feed end 12, the first antenna feed end 11 being a positive terminal and the second antenna feed end 12 being a negative terminal; two rectangular conductive rings 13 (respectively, a first conductive ring 131 and a second conductive ring 132) coupled between the first antenna feed end 11 and the second antenna feed end 12, both of which are different in length and uniform in width, and one long side of each conductive ring 13 is formed by the conductive side frame 20 of the electronic device 100. When the antenna assembly 10 is in a transmitting mode, the first antenna feed end 11 and the second antenna feed end 12 can introduce high-frequency current emitted by the transmitting device in the electronic device 100 into the antenna assembly 10, so that the conductive ring 13 can generate and radiate electromagnetic waves, and other receiving devices can receive the radiation to obtain the information carried by the radiation, thereby achieving signal transmission; when the antenna assembly 10 is in a receiving mode, the conductive ring 13 converts the collected electromagnetic waves into current and transmits it to the receiving device in the electronic device 100 for processing, thereby achieving signal reception.

[0039] In one example, an electronic device 100 is a tablet computer, and an antenna structure is provided in the tablet computer. Figure 4As shown, the antenna structure may include: a first antenna feed end 11 and a second antenna feed end 12, wherein the first antenna feed end 11 is a positive terminal and the second antenna feed end 12 is a negative terminal; a rectangular conductive ring 13 (a first conductive ring 131) coupled between the first antenna feed end 11 and the second antenna feed end 12, wherein one long side of the conductive ring 13 is formed by the conductive side frame 20 of the electronic device 100. When the antenna structure is in a transmitting mode, the first antenna feed end 11 and the second antenna feed end 12 can introduce high-frequency current emitted by the transmitting device in the electronic device 100 into the antenna structure, so that the conductive ring 13 can generate and radiate electromagnetic waves, and other receiving devices can receive the radiation to obtain the information carried by the radiation, thereby achieving signal transmission; when the antenna structure is in a receiving mode, the conductive ring 13 converts the collected electromagnetic waves into current and transmits it to the receiving device in the electronic device 100 for processing, thereby achieving signal reception.

[0040] Combining the above three examples and Figure 5 It can be seen that when the number of the conductive ring 13 is one, the impedance matching corresponding to the antenna structure is poor; when the number of the conductive ring 13 is two, a resonance point with good impedance matching appears, so that the bandwidth of the antenna assembly 10 is widened; when the number of the conductive ring 13 is three, the high-frequency resonance point of the antenna assembly 10 moves to the high frequency, so that the bandwidth of the antenna assembly 10 is further widened (as shown in FIG. Figure 5 The bandwidth of the antenna shown in the figure can cover the bandwidth of Wi-Fi 6 / Wi-Fi 7. In this way, the number of conductive rings 13 can be increased according to the bandwidth requirements and the appropriate setting position and setting size can be selected to flexibly adjust the bandwidth of the antenna assembly 10.

[0041] In this embodiment, the antenna assembly 10 is coupled with multiple conductive loops 13 between the two antenna feed ends to generate different radiation paths and have different resonant frequency points / grounding points, thereby achieving good impedance matching at multiple resonant frequency points, so that the antenna assembly 10 can operate effectively over a wider frequency range, thereby widening the operating bandwidth of the antenna assembly 10 and meeting the user's usage needs, and meeting the requirements of relevant certification specifications. In addition, at least a portion of each conductive loop 13 is formed by the conductive side frame 20 of the electronic device 100, so that the metal side frame of the electronic device 100 participates in the radiation as part of the antenna assembly 10, thereby widening the antenna bandwidth while reducing the manufacturing cost of the antenna assembly 10, reducing the volume of the antenna assembly 10, and simplifying the structure of the antenna assembly 10.

[0042] In some embodiments, see Figures 1 to 3As shown, the conductive side frame 20 is provided with a grounding portion 134 corresponding to each of the at least two conductive rings 13 to ground each conductive ring 13 respectively; the positions of the grounding portions 134 of different conductive rings 13 are different.

[0043] That is, each conductive ring 13 is grounded via a grounding portion 134, and the grounding portion 134 is provided on the conductive side frame 20. Here, each conductive ring 13 can be grounded via the grounding portion 134 provided on the conductive side frame 20, thereby reducing energy loss of the radio frequency signal during transmission, reducing electromagnetic interference, and ensuring safe signal transmission.

[0044] In some embodiments, see Figure 1 and Figure 2 As shown, when the number of the conductive rings 13 is greater than or equal to three, the distribution direction of the multiple grounding portions 134 corresponding to the multiple conductive rings 13 is aligned with the length direction of the conductive side frame 20 (eg, Figure 1 and Figure 2 The lengths between adjacent grounding portions 134 decrease along the length direction of the conductive side frame 20 .

[0045] In other words, the grounding portion 134 of each conductive ring 13 is disposed on the conductive side frame 20, so that the conductive side frame 20 is provided with a plurality of grounding portions 134, and the plurality of grounding portions 134 are distributed along the length direction of the conductive side frame 20, and along the length direction of the conductive side frame 20, the distance between adjacent grounding portions 134 is decreasing. For example: see Figure 1 and Figure 2As shown, the number of the conductive rings 13 is three, namely the first conductive ring 131, the second conductive ring 132 and the third conductive ring 133. The grounding portion 134 of the first conductive ring 131, the grounding portion 134 of the second conductive ring 132 and the grounding portion 134 of the third conductive ring 133 are sequentially arranged along the length direction of the conductive side frame 20, and the length between the grounding portion 134 of the first conductive ring 131 and the grounding portion 134 of the second conductive ring 131 is greater than the length between the grounding portion 134 of the second conductive ring 132 and the grounding portion 134 of the third conductive ring 133. For another example, the number of the conductive rings 13 is four, namely the first conductive ring 131, the second conductive ring 132, the third conductive ring 133 and the third conductive ring 134. The four conductive rings, namely, the grounding portion 134 of the first conductive ring 131, the grounding portion 134 of the second conductive ring 132, the grounding portion 134 of the third conductive ring 133, and the grounding portion 134 of the fourth conductive ring, are sequentially arranged along the length direction of the conductive side frame 20. The length between the grounding portion 134 of the first conductive ring 131 and the grounding portion 134 of the second conductive ring 131 is greater than the length between the grounding portion 134 of the second conductive ring 132 and the grounding portion 134 of the third conductive ring 133. The length between the grounding portion 134 of the second conductive ring 132 and the grounding portion 134 of the third conductive ring 133 is greater than the length between the grounding portion 134 of the third conductive ring 133 and the grounding portion 134 of the fourth conductive ring.

[0046] In this embodiment, the distribution direction of the multiple grounding portions 134 corresponding to the multiple conductive rings 13 is consistent with the length direction of the conductive side frame 20, and the length between adjacent grounding portions 134 tends to decrease along the length direction of the conductive side frame 20. In this way, the arrangement of the multiple conductive rings 13 can be made more regular and orderly, with a good visual effect, while widening the working bandwidth of the antenna assembly 10.

[0047] In some embodiments, see Figures 1 to 3 As shown, at least two conductive loops 13 have a common portion on one side near two antenna feed terminals, namely, first antenna feed terminal 11 and second antenna feed terminal 12. Alternatively, different conductive loops 13 have a common portion, and this common portion is located near first antenna feed terminal 11 and second antenna feed terminal 12.

[0048] In this embodiment, different conductive rings 13 have a common portion, so that the material used in the antenna assembly 10 can be reduced, thereby reducing the volume of the antenna assembly 10 and lowering the manufacturing cost of the antenna assembly 10 .

[0049] In some embodiments, see Figures 1 to 3As shown, at least two conductive rings 13 may include: a first conductive ring 131 and a second conductive ring 132; the first conductive ring 131 may include: a first segment 1311, a second segment 1312, a third segment 1313 and a fourth segment 1314, the first segment 1311 is formed by the conductive side frame 20 of the electronic device 100, one end of the second segment 1312 and one end of the third segment 1313 are respectively connected to the two ends of the first segment 1311, and there are two antenna feeding ends between one end of the fourth segment 1314 and the other end of the second segment 1312, and the other end of the fourth segment 1314 is connected to the other end of the third segment 1313; the second conductive ring 132 includes: a fifth segment 1321, a sixth section 1322, a seventh section 1323 and an eighth section 1324, the fifth section 1321 is formed by the conductive side frame 20 of the electronic device 100, part of the fifth section 1321 overlaps with the first section 1311 and part of the fifth section 1321 is located at the end of the first section 1311 away from the second section 1312, one end of the sixth section 1322 and one end of the seventh section 1323 are respectively connected to the two ends of the fifth section 1321, the sixth section 1322 overlaps with the second section 1312, there are two corresponding antenna feeding ends between one end of the eighth section 1324 and the other end of the sixth section 1322, and the other end of the eighth section 1324 is connected to the other end of the seventh section 1323.

[0050] Here, the first segment 1311 of the first conductive loop 131 may be opposite the fourth segment 1314, the second segment 1312 may be opposite the third segment 1313, and two antenna feed terminals (i.e., the first antenna feed terminal 11 and the second antenna feed terminal 12) may be located between the second segment 1312 and the fourth segment 1314. The fifth segment 1321 of the second conductive loop 132 may be opposite the eighth segment 1324, and the sixth segment 1322 may be opposite the seventh segment 1323. Two antenna feed terminals (i.e., the first antenna feed terminal 11 and the second antenna feed terminal 12) may be located between the sixth segment 1322 and the eighth segment 1324. Furthermore, the fifth segment 1321 covers the first segment 1311 and has a portion that is longer than the first segment 1311 and is located at the end of the first segment 1311 away from the second segment 1312. Furthermore, the sixth segment 1322 covers the second segment 1312 and has the same length as the second segment 1312. The first conductive ring 131 or the second conductive ring 132 may be in a quadrilateral shape such as a rectangle, a trapezoid, or a diamond.

[0051] In this embodiment, the common portion of the first conductive ring 131 and the second conductive ring 132 is at least the first segment 1311 and the second segment 1312 of the first conductive ring 131, and the first segment 1311 is formed by the conductive side frame 20 of the electronic device 100, so as to further reduce the volume of the antenna assembly 10, reduce the manufacturing cost of the antenna assembly 10, and simplify the complexity of the antenna assembly 10.

[0052] In some embodiments, see Figures 1 to 3As shown, a portion of the eighth segment 1324 overlaps with the fourth segment 1314 and is located at the end of the fourth segment 1314 away from the second segment 1312. In other words, the eighth segment 1324 and the fourth segment 1314 share a common portion, which is the fourth segment 1314. This increases the length of the common portion, further reducing the volume of the antenna assembly 10 and the manufacturing cost of the antenna assembly 10 while simplifying the complexity of the antenna assembly 10. Furthermore, because the first conductive ring 131 and the second conductive ring 132 both correspond to the two antenna feed terminals and have the same width, the arrangement of the first conductive ring 131 and the second conductive ring 132 is more regular and orderly, creating a better visual effect.

[0053] In some embodiments, see Figure 1 and Figure 2 As shown, the at least two conductive rings 13 may further include: a third conductive ring 133; the third conductive ring 133 may include: a ninth segment 1331, a tenth segment 1332, an eleventh segment 1333 and a twelfth segment 1334. The ninth segment 1331 is formed by the conductive side frame 20 of the electronic device 100. Part of the ninth segment 1331 overlaps with the fifth segment 1321 and is partially located at the end of the fifth segment 1321 away from the sixth segment 1322. One end of the tenth segment 1332 and one end of the eleventh segment 1333 are respectively connected to two ends of the ninth segment 1331. The tenth segment 1332 overlaps with the sixth segment 1322. Two antenna feeding ends correspond between one end of the twelfth segment 1334 and the other end of the tenth segment 1332. The other end of the twelfth segment 1334 is connected to the other end of the eleventh segment 1333. Part of the twelfth segment 1334 overlaps with the eighth segment 1324 and is partially located at the end of the eighth segment 1324 away from the sixth segment 1322.

[0054] Alternatively, there are three conductive rings 13, each extending from the two antenna feed terminals along the length of the conductive side frame 20. The different conductive rings 13 have the same width but different lengths, and the portions near the two feed terminals overlap to form a shared portion. With three conductive rings 13, the high-frequency resonance point of the antenna assembly 10 shifts toward higher frequencies, broadening the bandwidth of the antenna assembly 10. Furthermore, because the first conductive ring 131, the second conductive ring 132, and the third conductive ring 133 all correspond to the two antenna feed terminals and have the same width, the arrangement of the first conductive ring 131, the second conductive ring 132, and the third conductive ring 133 is more regular and orderly, creating a better visual effect.
