DETAILED DESCRIPTION

[0055] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, the same numbers are used to indicate the same or similar components. The embodiments described in the following exemplary embodiments do not represent all the implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the appended claims. It should also be understood that the term "and / or" as used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0056] With the development of electronic devices, the antenna radiator for wireless communication is integrated in the conductive frame of the electronic device, avoiding occupying the internal space of the electronic device. As the working frequency band of the antenna radiator gradually increases, in order to transmit signals of multiple frequency bands, multiple frame segments in the conductive frame need to be occupied as antenna radiators.

[0057] In the related art, an antenna assembly is disclosed, as shown in the figure. Figure 1 The antenna assembly includes a conductive middle frame. The conductive middle frame includes a conductive bezel 10 and a middle frame body 20. The conductive bezel 10 includes a first bezel segment 11, a second bezel segment 12, and a third bezel segment 13. The first bezel segment 11, the second bezel segment 12, and the third bezel segment 13 are all arranged in a spaced manner with the middle frame body 20. The first bezel segment 11 constitutes a first antenna radiator, and the working frequency band of the first antenna radiator is the L1 frequency band of the Global Positioning System (GPS), the 2.4G frequency band of the WIFI signal, and the 5G frequency band of the WIFI signal. The second bezel segment 12 constitutes a second antenna radiator, and the working frequency band of the second antenna radiator is the medium-high frequency band (MHB). The third bezel segment 13 constitutes a third antenna radiator, and the working frequency band of the third antenna radiator is the N77 frequency band. Among them, the first bezel segment 11 and the third bezel segment 13 have a break joint, and the second bezel segment 12 and the third bezel segment 13 have a break joint. When the current flows from the grounding point GND1 of the first bezel segment 11 to the grounding end of the middle frame body 20, the current flowing through the grounding end flows reversely to the second bezel segment 12 and the third bezel segment 13 through the grounding point GND1 of the second bezel segment 12 and the grounding point GND1 of the third bezel segment 13. As shown in the figure, Figure 2 Since the 2.4G frequency band of the WIFI signal and part of the working frequency band of the medium-high frequency band are the same, the reverse current will affect the efficiency of the second antenna radiator, and there is an efficiency depression of about 1dB between the signal frequency of 2500KHz and 2640KHz. Among them, the abscissa represents the signal frequency, and the ordinate represents the antenna efficiency.

[0058] Based on this, the present disclosure provides an antenna assembly, which can reduce the interference between signals with the same frequency band by suppressing the current flowing from the grounding point of the first bezel segment to the grounding end through the suppression circuit and arranging the antenna radiators with the same working frequency band in a spaced manner, thereby improving the efficiency of the antenna assembly.

[0059] An example embodiment of the present disclosure provides an antenna assembly, as shown in the figure. Figure 3As shown, the antenna assembly includes a conductive frame 10, a plurality of matching circuits 30 and a suppression circuit 40. The conductive frame 10 includes a first frame segment 11 and a second frame segment 12. The first frame segment 11 constitutes a first antenna radiator and the second frame segment 12 constitutes a second antenna radiator. The first antenna radiator and the second antenna radiator have a same frequency band. A partial matching circuit 30 is electrically connected between the first frame segment 11 and a first signal source 50, and another partial matching circuit 30 is electrically connected between the second frame segment 12 and a second signal source 60. The suppression circuit 40 has a first end electrically connected to a ground point GND1 of the first frame segment 11 and a second end electrically connected to a ground end GND2. The suppression circuit 40 is configured to suppress a current flowing from the ground point GND1 of the first frame segment 11 to the ground end GND2. The ground point GND1 of the second frame segment 12 is electrically connected to the ground end GND2.

[0060] In the embodiment, the antenna assembly includes a conductive frame, a plurality of matching circuits and a suppression circuit. The matching circuits are electrically connected to corresponding first frame segments or second frame segments of the conductive frame. The suppression circuit is electrically connected between a ground point of a first frame segment and a ground end. The suppression circuit suppresses a current flowing from the ground point of the first frame segment to the ground end, thereby reducing a current flowing from the ground end to the ground point of a second frame segment. In the case that the first antenna radiator and the second antenna radiator radiate signals of the same frequency, the suppression circuit reduces the interference of the signal in the first antenna radiator to the signal in the second antenna radiator, thereby improving the efficiency of the antenna assembly.

[0061] In one embodiment, as shown in FIG. 1, the suppression circuit 40 includes a first capacitor C1. A first end of the first capacitor C1 is electrically connected to the ground point GND1 of the first frame segment 11, and a second end of the first capacitor C1 is electrically connected to the ground end GND2. Figure 4

[0062] In the embodiment, the capacitor can suppress the current flow. By electrically connecting the first capacitor between the ground point of the first frame segment and the ground end, the suppression effect of the suppression circuit on the current is improved. Moreover, the capacitor has a simple structure, and the suppression circuit has a simple structure, thereby reducing the complexity of the structure of the antenna assembly.

[0063] Exemplarily, the suppression circuit 40 can include one or more first capacitors C1. In the case that the number of the first capacitors C1 is plural, the plural first capacitors C1 are connected in series and electrically connected between the ground point GND1 of the first frame segment 11 and the ground end GND2, thereby improving the suppression effect of the suppression circuit on the current.

[0064] ​Exemplarily, the first capacitor C1 can have a value ranging from 0.1 pF to 35 pF. The first capacitor C1 can have a value of 0.5 pF, 1 pF, 30 pF, 33 pF, or the like.

[0065] In an embodiment, the first frame section 11 is a floating frame section.

[0066] In the embodiment, the first frame section is set as a floating frame section, so that the first frame section is separated from the frame sections on both sides to reduce the interference of the signal radiated by the first antenna radiator on the signal radiated by the antenna radiator formed by the other frame sections, thereby improving the efficiency of the antenna assembly.

[0067] In an embodiment, as shown in FIG. 1, the part between the two ends of the first frame section 11 constitutes a first radiating branch 111 of the first antenna radiator. The part between the first feed point of the second frame section 12 and the ground point GND1 of the second frame section 12 constitutes a second radiating branch 121 of the second antenna radiator. Figure 5

[0068] In the embodiment, since the floating frame section is separated from the frame sections on both sides, the part between the two ends of the first frame section constitutes the first radiating branch, so that the entire floating frame section radiates signals as the first radiating branch, thereby improving the strength of signal radiation. Moreover, by constituting the second radiating branch with the part between the first feed point and the ground point of the second frame section, signal radiation can be achieved, thereby improving the reliability of the antenna assembly.

[0069] In an embodiment, the operating frequency band of the first radiating branch 111 includes the N77 frequency band and the 2.4G frequency band of the WIFI signal. The operating frequency band of the second radiating branch 121 includes the medium-high frequency band.

[0070] In the embodiment, since the 2.4G frequency band of the WIFI signal and part of the medium-high frequency band are the same, by setting the first frame section as a floating frame section and setting the suppression circuit between the first frame section and the ground point, the interference of the signal of the 2.4G frequency band of the WIFI signal on the signal of the medium-high frequency band can be suppressed, thereby improving the efficiency of the antenna assembly. Moreover, since the N77 frequency band and the 2.4G frequency band of the WIFI signal are different, the signal of the N77 frequency band and the signal of the 2.4G frequency band of the WIFI signal will not interfere with each other when radiating. By multiplexing the first frame section to transmit signals of different frequency bands, it is avoided to occupy additional frame sections for signal radiation, thereby reducing the complexity of the structure of the antenna assembly.

[0071] In an embodiment, as shown in FIG. 1, the part between the two ends of the first frame section 11 constitutes a first radiating branch 111 of the first antenna radiator. The part between the first feed point of the second frame section 12 and the ground point GND1 of the second frame section 12 constitutes a second radiating branch 121 of the second antenna radiator. Figure 6 ​As shown, the plurality of matching circuits 30 includes a first matching circuit 31 and a second matching circuit 32. The first matching circuit 31 is electrically connected between the second feeding point of the first frame segment 11 and the first signal source 50. The second matching circuit 32 is electrically connected between the first feeding point of the second frame segment 12 and the second signal source 60.

[0072] In this embodiment, by setting the first matching circuit between the second feeding point and the first signal source, the first matching circuit can perform impedance transformation to achieve optimal impedance matching between the first radiating branch and the first signal source. By setting the second matching circuit between the first feeding point and the second signal source, the second matching circuit can perform impedance transformation to achieve optimal impedance matching between the second radiating branch and the second signal source. By adding the corresponding matching circuit between the feeding point and the signal source to perform impedance matching, the reflection and loss of energy are reduced, thereby improving the efficiency of the antenna assembly.

[0073] Exemplarily, the first matching circuit 31 and the second matching circuit 32 can be composed of different passive devices, respectively.

[0074] In an embodiment, as shown, Figure 7 The first matching circuit 31 includes a first inductor L1, a second inductor L2, a third inductor L3, a second capacitor C2, a third capacitor C3, and a fourth capacitor C4. The first end of the first inductor L1 is used to be electrically connected with the first signal source 50. The first end of the second capacitor C2 is electrically connected with the second end of the first inductor L1, and the second end of the second capacitor C2 is used to be electrically connected with the ground terminal GND2. The first end of the second inductor L2 is electrically connected with the second end of the first inductor L1 and the first end of the second capacitor C2, and the second end of the second inductor L2 is used to be electrically connected with the ground terminal GND2. The first end of the third capacitor C3 is electrically connected with the second end of the first inductor L1, the first end of the second capacitor C2, and the first end of the second inductor L2. The first end of the third inductor L3 is electrically connected with the second end of the third capacitor C3, and the second end of the third inductor L3 is used to be electrically connected with the ground terminal GND2. The first end of the fourth capacitor C4 is electrically connected with the second end of the third capacitor C3 and the first end of the third inductor L3, and the second end of the fourth capacitor C4 is electrically connected with the second feeding point.

[0075] In this embodiment, since the inductors and capacitors can change the impedance, the first inductor, the second inductor, the third inductor, the second capacitor, the third capacitor, and the fourth capacitor are connected in series and in parallel to perform impedance matching, thereby improving the efficiency of the antenna assembly.

[0076] Exemplarily, the first inductor L1 can have a value ranging from 1nH to 5nH. The first inductor L1 can have a value of 2nH, 3nH, 4nH, etc. The second inductor L2 can have a value ranging from 1nH to 5nH. The second inductor L2 can have a value of 2nH, 3nH, 4nH, etc. The third inductor L3 can have a value ranging from 50nH to 150nH. The third inductor L3 can have a value of 90nH, 100nH, 110nH, etc. The second capacitor C2 can have a value ranging from 0.1pF to 0.5pF. The second capacitor C2 can have a value of 0.2pF, 0.3pF, 0.4pF, etc. The third capacitor C3 can have a value ranging from 0.5pF to 1.0pF. The third capacitor C3 can have a value of 0.6pF, 0.7pF, 0.8pF, etc. The fourth capacitor C4 can have a value ranging from 30pF to 35pF. The fourth capacitor C4 can have a value of 32pF, 33pF, 34pF, etc.

[0077] In an embodiment, as shown in FIG. 1, the conductive frame 10 further includes a third frame segment 13. The second frame segment 12 and the third frame segment 13 are respectively located on two sides of the first frame segment 11. The third frame segment 13 has a gap with the first frame segment 11, and the third frame segment 13 constitutes a third antenna radiator. The partial matching circuit 30 is electrically connected between the third frame segment 13 and at least one third signal source 70. Figure 8

[0078] In the embodiment, the third antenna radiator is constituted by the third frame segment which is spaced apart from the first frame segment. The third antenna radiator can radiate signals of different frequency bands from the first antenna radiator and the second antenna radiator, and reduce interference generated in the process of radiating different signals, thereby improving the efficiency of the antenna assembly.

[0079] Exemplarily, the ground point GND1 of the third frame segment 13 is used to be electrically connected with the ground terminal GND2.

[0080] In an embodiment, as shown in FIG. 1, the conductive frame 10 further includes a third frame segment 13. The second frame segment 12 and the third frame segment 13 are respectively located on two sides of the first frame segment 11. The third frame segment 13 has a gap with the first frame segment 11, and the third frame segment 13 constitutes a third antenna radiator. The partial matching circuit 30 is electrically connected between the third frame segment 13 and at least one third signal source 70. Figure 9 In the embodiment, the third antenna radiator is constituted by the third frame segment which is spaced apart from the first frame segment. The third antenna radiator can radiate signals of different frequency bands from the first antenna radiator and the second antenna radiator, and reduce interference generated in the process of radiating different signals, thereby improving the efficiency of the antenna assembly.

[0081]

[0082] ​​For example, the second feed point and the ground point GND1 of the first frame segment 11 can be located on the side of the first frame segment 11 closer to the third frame segment 13, so as to increase the distance between the ground point GND1 of the first frame segment 11 and the ground point GND1 of the second frame segment 12, thereby extending the current flow path to reduce the interference generated between signals of the same frequency band during radiation.

[0083] In one embodiment, the operating frequency band of the third radiating stub 131 includes the 5G band of Wi-Fi signals. The operating frequency band of the fourth radiating stub 132 includes the B32 band and the L1 band of the Global Positioning System.

[0084] In this embodiment, by radiating 5G frequency band signals of WIFI signals with the third radiating branch and radiating B32 frequency band and L1 frequency band signals of the Global Positioning System with the fourth radiating branch, the first, second, third, and fourth radiating branches can radiate signals of multiple frequency bands respectively with less interference between them, thereby improving the reliability of the antenna assembly.

[0085] In one embodiment, the plurality of matching circuits 30 includes a third matching circuit 33 and a fourth matching circuit 34. The third matching circuit 33 is electrically connected between a third feed point of the third frame segment 13 and a third signal source 70, and the fourth matching circuit 34 is electrically connected between a fourth feed point of the third frame segment 13 and another third signal source.

[0086] In this embodiment, a third matching circuit is set between the third feed point and a third signal source. This third matching circuit can perform impedance transformation to achieve optimal impedance matching between the third radiating stub and the third signal source. Similarly, a fourth matching circuit is set between the fourth feed point and another third signal source. This fourth matching circuit can also perform impedance transformation to achieve optimal matching impedance between the fourth radiating stub and the other third signal source. By adding corresponding matching circuits between the feed point and the signal source for impedance matching, energy reflection and loss are reduced, thereby improving the efficiency of the antenna assembly.

[0087] For example, the third matching circuit 33 and the fourth matching circuit 34 may each be composed of different passive devices.

[0088] In one embodiment, such as Figure 10 As shown, the conductive frame 10 also includes a fourth frame segment 14 and a fifth frame segment 15. The fourth frame segment 14 is located between the first frame segment 11 and the second frame segment 12, and there is a gap between the fourth frame segment 14 and both the first frame segment 11 and the second frame segment 12. The fifth frame segment 15 is located between the first frame segment 11 and the third frame segment 13, and there is a gap between the fifth frame segment 15 and both the first frame segment 11 and the third frame segment 13.

[0089] In this embodiment, by setting a fourth and fifth frame segments that do not radiate signals, the first frame segment can be separated from the second and third frame segments, and the interference caused by different signals to each other during the radiation process can be reduced, thereby improving the efficiency of the antenna assembly.

[0090] For example, both the fourth frame segment 14 and the fifth frame segment 15 are electrically connected to the ground terminal GND2.

[0091] An exemplary embodiment of this disclosure provides an antenna assembly, such as Figure 11As shown, the antenna assembly includes a first frame segment 11, a second frame segment 12, a third frame segment 13, a fourth frame segment 14, a fifth frame segment 15, two first capacitors C1, a second capacitor C2, a third capacitor C3, a fourth capacitor C4, a first inductor L1, a second inductor L2, a third inductor L3, a second matching circuit 32, a third matching circuit 33, and a fourth matching circuit 34. The first frame segment 11 is a floating frame segment. The second frame segment 12 and the third frame segment 13 are located on either side of the first frame segment 11. The fourth frame segment 14 is located between the first frame segment 11 and the second frame segment 12, and there are gaps between the fourth frame segment 14 and both the first and second frame segments 11 and 12. The fifth frame segment 15 is located between the first frame segment 11 and the third frame segment 13, and there are gaps between the fifth frame segment 15 and both the first and third frame segments 11 and 13. The second feed point of the first frame segment 11 is electrically connected to the second terminal of the fourth capacitor C4. The first terminal of the fourth capacitor C4 is electrically connected to the second terminal of the third capacitor C3 and the first terminal of the third inductor L3. The first terminal of the third capacitor C3 is electrically connected to the second terminal of the first inductor L1, the first terminal of the second capacitor C2, and the first terminal of the second inductor L2. The first terminal of the first inductor L1 is used to connect to the first signal source 50. The second terminals of the second capacitor C2, the second terminal of the second inductor L2, and the second terminal of the third inductor L3 are all used to connect to the ground terminal GND2. The two first capacitors C1 are connected in series between the ground point GND1 and the ground terminal GND2 of the first frame segment 11. The second feed point of the second frame segment 12 is electrically connected to the second signal source 60 through the second matching circuit 32, and the ground point GND1 of the second frame segment 12 is used to connect to the ground terminal GND2. The third feed point of the third frame segment 13 is electrically connected to a third signal source 70 through the third matching circuit 33. The fourth feed point of the third frame segment 13 is electrically connected to another third signal source 70 through the fourth matching circuit 34. The ground point GND1 of the third frame segment 13 is used to be electrically connected to the ground terminal GND2. Among them, the ground point GND1 of the first frame segment 11 is electrically connected to the first capacitor C1 through a spring contact. The ground points GND1 of the second frame segment 12 and the ground point GND1 of the third frame segment 13 are electrically connected to the ground terminal GND2 in a rib-grounding manner. The fourth frame segment 14 and the fifth frame segment 15 are electrically connected to the ground terminal GND2 in a rib-grounding manner.
