[0043] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0044] With the development of electronic technology, electronic devices (such as smart phones, tablet computers, etc.) are becoming more and more popular in people's daily lives and their communication functions are becoming more and more powerful. For example, electronic devices need to have near-field communication functions, navigation functions, and far-field communication functions. Because different communication functions correspond to different communication frequency bands, and even under the same communication function, it can be subdivided into multiple communication frequency bands.

[0045] For example, the communication band of the near field communication function may include a Bluetooth communication band, a WIFI band, and an NFC communication band. The WIFI band may, for example, include at least one of the following bands: a WIFI 2.4G band, a WIFI 5G band, and a WIFI 7 band. The communication band of the navigation function may include a GPS-L1 band and a GPS-L5 band. The far field communication band includes a low band (Low band, LB), a middle high band (Middle high band), and an ultra high band (Ultra high band, UHB). Specifically, the far field communication band may include each band and a combination band of the NR band and the LTE band to meet the wireless communication of electronic devices under 2G, 3G, 4G, 5G, or even 6G broadband. At present, the commonly used wireless communication band under 5G broadband is the UHB band, and the UHB band may specifically include the N77 band, the N78 band, and the N79 band.

[0046] In view of the need for electronic devices to work in multiple frequency bands, a common approach is to set multiple antennas corresponding to the multiple frequency bands in the electronic device. However, setting up multiple antennas will take up a large space, which is not conducive to the development of miniaturization and portability of electronic devices. Therefore, there is an urgent need for a technology that can arrange multiple antennas in a smaller space to realize multiple wireless communication functions.

[0047] Related art proposes that a co-body antenna assembly can be used to realize the functions of multiple antennas. The radiator of the co-body antenna can realize the co-body of multiple different antenna modes, and different antenna modes can meet different communication functions. The co-body form can also reduce the space occupied by the antenna assembly.

[0048] However, how to make the antenna assembly in the form of a co-body simultaneously cover the frequency bands used for navigation communication, near-field communication, and far-field communication while occupying a smaller space has become a technical problem that needs to be solved urgently.

[0049] As a feasible approach, Figure 1As shown, the antenna assembly 10 can be configured to include a first antenna unit 11 and a second antenna unit 12. The first antenna unit 11 includes a first radiator 111 and a first feed source 112. The second antenna unit 12 includes a second radiator 121, a second feed source 122, and a third feed source 123. A gap 13 is formed between the first radiator 111 and the second radiator 121, and the first radiator 111 and the second radiator 121 are coupled through the gap 13 to realize that the first antenna unit 11 and the second antenna unit 12 are a common body antenna with a common aperture. In other words, the first radiator 111 and the second radiator 121 belong to the same radiator, and the one radiator has a gap 13 to divide the one radiator into the first radiator 111 and the second radiator 121. The first antenna unit 11 or the second antenna unit 12 formed as a common body antenna can not only use its own radiator when working, but also use the radiator on the opposite side. At the same time, in conjunction with the different radio frequency signals (also called feeding current or excitation current) received or transmitted by the first feed source 112 , the second feed source 122 , and the third feed source 123 , the antenna assembly 10 can achieve transmission of multi-band signals.

[0050] It should be noted that the coupling in the embodiment of the present application is "capacitive coupling". The so-called "capacitive coupling" means that an electric field is generated between two radiators, and the signal of one radiator can be transmitted to the other radiator through the electric field. Correspondingly, the signal of the other radiator can be transmitted to the one radiator through the electric field, so that the two radiators can achieve electrical signal conduction even when they are not in direct contact or not directly connected. For example, the second radiator 121 is coupled with the first radiator 111 through the gap 13, which means that the second radiator 121 and the first radiator 111 generate an electric field, and the signal of the second radiator 121 can be transmitted to the first radiator 111 through the electric field, so that the second radiator 121 and the first radiator 111 can achieve electrical signal conduction even when they are not in direct contact or not directly connected. Correspondingly, the first radiator 111 can also generate an electric field with the second radiator 121, and the signal of the first radiator 111 can be transmitted to the second radiator 121 through the electric field, so that the first radiator 111 and the second radiator 121 can achieve electrical signal conduction even if they are not in direct contact or direct connection.

[0051] like Figure 2 As shown, the antenna assembly 10 can be applied in an electronic device 20. The electronic device 20 may include a top wall 21 and side walls 22 located on both sides of the top wall. Figure 2 As shown, the side wall is a first side wall 221 located on the left and a second side wall 222 located on the right. The first side wall 221 and the second side wall 222 are areas for gripping.

[0052] Continue to see Figure 1The first radiator 111 has a first ground terminal D, a first free terminal C and a first feeding point E. Figure 2 As shown, the first radiator 111 is usually located in the upper left corner of the electronic device, or the first radiator 111 extends from the top wall 21 of the electronic device 20 to the first side wall 221. The first ground terminal D is located at an end of the first radiator 111 away from the second radiator 121 and the first ground terminal D is used to ground GND1. The first free end C is located at an end of the first radiator 111 close to the second radiator 121. The first feeding point E is located between the first ground terminal D and the first free end C, and the first feed source 112 is connected to the first feeding point E. The radio frequency signal received or transmitted by the first feed source 112 can excite the first radiator 111 and / or the second radiator 121 to resonate in the first target frequency band. The first feed source 112 corresponds to the antenna ANT1, and the antenna ANT1 has a resonance mode corresponding to the first target frequency band.

[0053] Optionally, a first matching circuit M1 may be provided between the first feed source 112 and the first feeding point E. The first matching circuit M1 is used to perform impedance matching on the excitation signal sent by the first feed source 112 to excite the first radiator 111 and / or the second radiator to resonate in the first target frequency band, so that the antenna ANT1 corresponding to the first feed source 112 has a preset S parameter. At the same time, the first matching circuit M1 is also used to filter the radio frequency signal received or transmitted by the first feed source 112.

[0054] Continue to see Figure 1 The second radiator 121 has a second ground terminal H, a second free terminal I, a second feeding point F and a third feeding point G. The second ground terminal H is located at an end of the second radiator 121 away from the first radiator 111 and is connected to the ground GND2. The second free terminal I is located at an end of the second radiator 121 close to the first radiator 111 and there is the aforementioned gap 13 between the second free terminal I and the first free terminal C. The second feeding point F and the third feeding point G are located between the second ground terminal H and the second free terminal I.

[0055] The second feed source 122 is connected to the second feeding point F. The RF signal received or transmitted by the second feed source 122 can excite the first radiator 111 and / or the second radiator 121 to resonate in the second target frequency band. The second feed source 122 corresponds to the antenna ANT2, and the antenna ANT2 has a resonance mode corresponding to the second target frequency band.

[0056] Optionally, a second matching circuit M2 may also be provided between the second feed source 122 and the second feeding point F. The second matching circuit M2 is used to perform impedance matching on the excitation signal sent by the second feed source 122 to excite the first radiator 111 and / or the second radiator to resonate in the second target frequency band, so that the antenna ANT2 corresponding to the second feed source 122 has a preset S parameter.

[0057] The RF signal received or transmitted by the first feed source 112 can excite the first radiator 111 and / or the second radiator 121 to resonate, which may include: the RF signal received or transmitted by the first feed source 112 only excites the first radiator 111 to resonate, and / or, the RF signal received or transmitted by the first feed source 112 only excites the second radiator 121 to parasitic resonance, and / or, the RF signal received or transmitted by the first feed source 112 excites the first radiator 111 to resonate and excites the second radiator 121 to parasitic resonance.

[0058] Similarly, the RF signal received or transmitted by the second feed source 122 can excite the first radiator 111 and / or the second radiator 121 to resonate, including: the RF signal received or transmitted by the second feed source 122 only excites the second radiator 121 to resonate, and / or, the RF signal received or transmitted by the second feed source 122 only excites the first radiator 111 to parasitic resonance, and / or, the RF signal received or transmitted by the second feed source 122 excites the second radiator 121 to resonate and excites the first radiator 111 to parasitic resonance.

[0059] Continue to see Figure 1 The third feed source 123 is connected to the third feeding point G. The radio frequency signal received or transmitted by the third feed source 123 can excite the second radiator 121 to resonate in the third target frequency band. The third feed source 123 corresponds to the antenna ANT3, and the antenna ANT3 has a resonance mode corresponding to the third target frequency band.

[0060] Optionally, a third matching circuit M3 may be provided between the third feed source 123 and the third feeding point G. The third matching circuit M3 is used to perform impedance matching on the excitation signal sent by the third feed source 123 to excite the second radiator 121 to resonate in the third target frequency band, so that the antenna ANT3 corresponding to the third feed source 123 has a preset S parameter. In addition, the third matching circuit M3 is also used to filter the radio frequency signal received or transmitted by the third feed source 123.

[0061] In some embodiments, Figure 1As shown, the first ground terminal D can be connected to the ground GND1 through the switch circuit M4. In other words, one end of the switch circuit M4 is connected to the first ground terminal D, and the other end is connected to the ground GND1. The switch circuit M4 is used to switch the radiation frequency band of the first radiator 111 and / or filter and ground the first radiator 111. In some embodiments, the switch circuit M4 can be connected to the mainboard. It can be understood that the switch circuit M4 can also be called a matching circuit M4.

[0062] The embodiment of the present application does not specifically limit the connection method between the first ground terminal D and the ground GND1 and the second ground terminal H and the ground GND2. For example, the connection method between the ground terminal D or H and the ground includes but is not limited to direct electrical connection (such as welding); or indirect electrical connection to the ground through a coaxial line, a microstrip line, a radio frequency line, a conductive spring, a conductive adhesive, an embedded metal, or a middle frame connection of an electronic device where the antenna assembly is installed.

[0063] In another embodiment, the antenna assembly 10 itself has a reference ground, also called a ground pole or ground. The specific form of the reference ground includes but is not limited to a metal conductive plate, a metal conductive layer formed inside a flexible circuit board, a hard circuit board, etc. When the antenna assembly 10 is disposed in an electronic device, the reference ground of the antenna assembly 10 is electrically connected to the reference ground of the electronic device. In other embodiments, the antenna assembly 10 itself does not have a reference ground, and the first ground terminal D of the antenna assembly 10 is electrically connected to the reference ground of the electronic device or the reference ground of the electronic device in the electronic device through direct electrical connection or through an indirect electrical connection through a conductive member.

[0064] In some embodiments, the first target frequency band may include a first frequency band, a second frequency band, and a third frequency band. The first frequency band covers the GPS-L1 frequency band, which is a 1.575 GHZ frequency band. The second frequency band covers the WIFI2.4 frequency band, which is a 2.4-2.5 GHz frequency band. The third frequency band covers the 3G or 4G communication frequency band.

[0065] For example, Figure 3 As shown, the first frequency band can be represented by marked point 1, the frequency of marked point 1 is 1.5766 GHz, and the radiation efficiency is -8.0811 dB; the second frequency band can be represented by marked point 2, the frequency of marked point 2 is 2.4667 GHz, and the radiation efficiency is -9.9973 dB; the third frequency band can be represented by marked point 3, the frequency of marked point 3 is 2.9773 GHz, and the radiation efficiency is -15.904 dB.

[0066] Correspondingly, the antenna ANT1 has a first resonant mode, and the first resonant mode includes a first sub-resonant mode, a second sub-resonant mode, and a third sub-resonant mode for supporting the first frequency band, the second frequency band, and the third frequency band, respectively. Specifically, as shown by the arrowed line in FIG4(a), the first sub-resonant mode is a 1 / 4 wavelength mode from the first ground terminal D to the slot 13. As shown by the arrowed line in FIG4(b), the second sub-resonant mode is a 1 / 4 wavelength mode from the first feeding point E to the slot 13. As shown by the arrowed line in FIG4(c), the third sub-resonant mode is a unidirectional current mode from the first feed source 112 to the second ground terminal GND2.

[0067] In some embodiments, the second target frequency band may include a fourth frequency band, a fifth frequency band, a sixth frequency band, and a seventh frequency band. Among them, the fourth frequency band covers the LTE communication frequency band, and the LTE communication frequency band includes the frequency band of 4G communication and communication broadband below 4G. The fifth frequency band covers the UHB frequency band, which is a 5G communication broadband frequency band. The UHB frequency band may include the N78 frequency band, and the N78 frequency band is a 3.4-3.6GHz frequency band. The sixth frequency band covers the WIFI7 communication frequency band, and the WIFI7 communication frequency band is a 5.15-7.15GHz frequency band. The seventh frequency band covers the ultra-wideband (Ultra Wideband, UWB) communication frequency band, and the ultra-wideband communication frequency band is a frequency band of 6G communication and communication broadband below 6G.

[0068] For example, Figure 5 As shown, the fourth frequency band can be Figure 5 The marked points 1 and 2 in the figure indicate that the frequency of the marked point 1 is 2.3176 GHz and the radiation efficiency is -34.499 dB; the frequency of the marked point 2 is 2.9228 GHz and the radiation efficiency is -0.69303 dB. The fifth frequency band can be obtained by Figure 5 The marked points 3 and 4 in the figure indicate that the frequency of the marked point 3 is 3.5317 GHz (that is, the N78 frequency band), and the radiation efficiency is -8.6082 dB; the frequency of the marked point 4 is 4.4621 GHz, and the radiation efficiency is -6.3175 dB. The sixth frequency band can be Figure 5 The marked points 5, 6 and 7 in the figure indicate that the frequency of the marked point 5 is 5.4542 GHz and the radiation efficiency is -19.557 dB; the frequency of the marked point 6 is 5.9371 GHz and the radiation efficiency is -6.8246 dB; the frequency of the marked point 7 is 6.9292 GHz and the radiation efficiency is -10.009 dB. The seventh frequency band can be Figure 5 The marked point 8 in the figure indicates that the frequency of the marked point 8 is 7.9069 GHz and the radiation efficiency is -17.653 dB.

[0069] Accordingly, the antenna ANT2 has a second resonance mode, which includes Figure 5 The marked points 1 to 8 correspond to the first sub-resonance mode to the eighth sub-resonance mode respectively, and the first sub-resonance mode to the eighth sub-resonance mode are respectively used to support the frequency bands corresponding to the marked points 1 to 8. As shown by the arrowed line in FIG6(a), the first sub-resonance mode is a ring mode from the third feed 123 to the second feed 122, and the first sub-resonance mode can be obtained through the influence of the second matching circuit M2 and the third matching circuit M3; as shown by the arrowed line in FIG6(b), the second sub-resonance mode is a ring mode from the third feed 123 to the second feed 112; as shown by the arrowed line in FIG6(c), the third sub-resonance mode is a 1 / 4 wavelength mode from the second feed 112 to the slot 13; as shown by the arrowed line in FIG6(d), the fourth sub-resonance mode is a mode from the slot 13 to the switch The 3 / 4 wavelength mode is generated by the ground current on the main board of the circuit M4 part; as shown by the arrow line in Figure 6(e), the fifth sub-resonance mode is the 1 / 4 wavelength mode from the second feed source 122 to the slot 13; as shown by the arrow line in Figure 6(f), the sixth sub-resonance mode is the ring mode from the second feed source 122 to the ground GND2; as shown by the arrow line in Figure 6(g), the seventh sub-resonance mode is the 3 / 4 wavelength mode from the slot 13 to the switch circuit M4; as shown by the arrow line in Figure 6(h), the eighth sub-resonance mode is the 5 / 4 wavelength mode from the switch circuit M4 to the slot 13.

[0070] In some embodiments, the third target frequency band may include an LB frequency band. The LB frequency band includes a frequency band less than 1 GHz. Figure 7 As shown, the LB frequency band can be represented by the marked point 1, the frequency of the marked point 1 is 0.74327GHz, and the radiation efficiency is -10.3748dB. Accordingly, the antenna ANT3 has a third resonance mode, which is a resonance mode corresponding to the LB frequency band, and the third resonance mode is a 1 / 4 wavelength mode from the ground GND2 to the slot 13, and the third resonance mode is used to support the LB frequency band.

[0071] The embodiment of the present application does not specifically limit the lengths of the first radiator 111 and the second radiator 121. As an implementation, the length of the first radiator 111 corresponds to 1 / 4 of the medium wavelength of GPS, and the length of the second radiator 121 corresponds to 1 / 8-1 / 4 of the wavelength of the LB segment.

[0072] The antenna assembly 10 has the characteristics of small size, small footprint and wide frequency band coverage. However, as can be seen from the foregoing, since the first radiator 111 for implementing the GPS-L1 frequency band is located at the upper left corner of the electronic device, it is easily blocked by the user's hand, resulting in a decrease in navigation performance. In particular, when the electronic device is a foldable electronic device, after the cover is folded, the user's finger grip when holding the electronic device can just cover the first radiator 111, resulting in a significant decrease in the navigation and communication performance of the folded electronic device. At the same time, the antenna assembly 10 only covers one navigation frequency band (GPS-L1 frequency band) and has a limited coverage range. In summary, the navigation accuracy of the antenna assembly 10 is not high enough, and its navigation and communication performance needs to be further improved.

[0073] In view of this, the embodiment of the present application proposes a new antenna assembly. The antenna assembly is not only small in size and occupies a small space, but also can cover multiple communication frequency bands mentioned above. The second radiator for realizing the navigation frequency band in the antenna assembly is located on the top wall of the electronic device, which avoids the problem of blocking the navigation signal when the user holds it in his hand. At the same time, since the antenna assembly can cover the first navigation frequency band and the second navigation frequency band at the same time, the navigation performance is effectively improved.

[0074] Combine the following Figure 8 , the antenna assembly 80 in the embodiment of the present application is described in detail.

[0075] See Figure 8 The antenna assembly 80 is configured to include a first antenna unit 81 and a second antenna unit 82. The first antenna unit 81 includes a first radiator 811 and a first feed source 812. The second antenna unit 82 includes a second radiator 821 and a second feed source 822. A gap 83 is formed between the first radiator 811 and the second radiator 821, and the first radiator 811 and the second radiator 821 are coupled through the gap 83 to realize that the first antenna unit 81 and the second antenna unit 82 are common body antennas with a common aperture.

[0076] like Figure 8 As shown, the first radiator 811 also has a first ground terminal D', a first free end C' and a first feeding point E'. The first feed source 812 is connected to the first feeding point E' between the first ground terminal D' and the first free end C'. The radio frequency signal received or transmitted by the first feed source 812 can excite the first radiator 811 and / or the second radiator 821 to resonate in the first target frequency band. The first feed source 812 corresponds to the antenna ANT1', and the antenna ANT1' has a first resonant mode that supports the first target frequency band.

[0077] The second radiator 821 also has a second ground terminal H', a second free end I' and a second feeding point F'. There is a gap 83 between the second free end I' and the first free end C'. The second feeding point F' is located between the second ground terminal H' and the second free end I'. The second feed source 822 is connected to the second feeding point F', and the RF signal received or transmitted by the second feed source 822 can excite the second radiator 821 and / or the first radiator 811 to resonate in the second target frequency band. The second feed source 822 corresponds to the antenna ANT2', and the antenna ANT2' has a second resonant mode that supports the second target frequency band.

[0078] The embodiment of the present application does not specifically limit the shape of the first radiator 811 or the second radiator 821. The shapes of the first radiator 811 or the second radiator 821 include but are not limited to bends, strips, sheets, rods, coatings, films, etc. When the first radiator 811 or the second radiator 821 is in a strip shape, the present application does not limit the extension track of the first radiator 811 or the second radiator 821. For example, the first radiator 811 or the second radiator 821 can extend in a straight line, a curve, a multi-section bend, etc. In addition, the first radiator 811 or the second radiator 821 can be a line with uniform width on the extension track, or a strip with unequal width such as a gradient width and a widened area.

[0079] As an example, Figure 8 As shown, the first radiator 811 may be in the shape of a 90-degree folded line. The first ground end D' and the first free end C' are two ends of the first radiator 811. The second radiator 821 may be in the shape of a straight line. The second ground end H' and the second free end I' are two ends of the second radiator 821.

[0080] Combined with the following Fig. 20 and Fig.21 As shown, the first radiator 811 is arranged to extend from the top wall 21 of the electronic device 20 to the side wall 22 of the electronic device, and the second radiator is only arranged on the top wall 21 of the electronic device 20 .

[0081] In an embodiment of the present application, the first radiator 811 and / or the second radiator 821 can be formed in any one or more ways including a flexible printed circuit (FPC) antenna radiator, a laser direct structuring (LDS) antenna radiator, a printed direct structuring (PDS) antenna radiator, or a metal frame.

[0082] In some embodiments, Figure 8As shown, the second antenna unit 82 may further include a third feed 823. The third feed 823 is electrically connected to the second radiator 821, and the radio frequency signal received or transmitted by the third feed 823 may excite the second radiator 821 to resonate in the third target frequency band. The third feed 823 corresponds to ANT3', and the antenna ANT3' has a third resonance mode supporting the third target frequency band.

[0083] It should be noted that in the embodiment of the present application, the first target frequency band is a non-navigation frequency band. The embodiment of the present application does not specifically limit the type of the first target frequency band, as long as the first target frequency band is a non-navigation frequency band. In some embodiments, the first target frequency band may include a WIFI5G frequency band. Optionally, the first target frequency band may also include a UHB frequency band.

[0084] The second target frequency band and the third target frequency band are related frequency bands including the navigation frequency band. The difference is that the second target frequency band includes the first navigation frequency band, the third target frequency band may include the second navigation frequency band, and the second target frequency band may include a non-navigation frequency band in addition to the first navigation frequency band. Among them, one of the first navigation frequency band and the second navigation frequency band is the GPS-L1 frequency band, and the other is the GPS-L5 frequency band. In other words, if the first navigation frequency band is the GPS-L1 frequency band, the second navigation frequency band is the GPS-L5 frequency band, and conversely, if the first navigation frequency band is the GPS-L5 frequency band, the second navigation frequency band is the GPS-L1 frequency band. The embodiment of the present application does not specifically limit the non-navigation frequency band included in the second target frequency band. As an implementation method, the non-navigation frequency band of the second target frequency band may include the WIFI2.4G frequency band. As another implementation method, the second target frequency band may also include the UHB frequency band at the same time.

[0085] From the above content, it can be known that the first target frequency band, the second target frequency band and the third target frequency band can be a combination of multiple different frequency bands. For example, the first target frequency band includes the WIFI5G frequency band + UHB frequency band, the second target frequency band includes the WIFI2.4G frequency band + GPS-L1 frequency band, and the third target frequency band includes the GPSL5 frequency band. Alternatively, the first target frequency band includes the WIFI5G frequency band + UHB frequency band, the second target frequency band includes the WIFI2.4G frequency band + GPS-L5 frequency band, and the third target frequency band includes the GPSL1 frequency band. Alternatively, the first target frequency band includes the WIFI5G frequency band, the second target frequency band includes the WIFI2.4G frequency band + GPS-L1 frequency band + UHB frequency band, and the third target frequency band includes the GPSL5 frequency band. Alternatively, the first target frequency band includes the WIFI5G frequency band, the second target frequency band includes the WIFI2.4G frequency band + GPS-L5 frequency band + UHB frequency band, and the third target frequency band includes the GPSL1 frequency band.

[0086] By incorporating the implementation of the GPS-L5 frequency band into the implementation branch of the GPS-L1 frequency band, in other words, by using the same branch to generate both the GPS-L1 frequency band and the GPS-L5 frequency band, the antenna assembly 80 can cover more navigation frequency bands and thus have better navigation performance while also improving the radiation efficiency of the GPS-L1 frequency band and the GPS-L5 frequency band at the same time.

[0087] The embodiment of the present application does not specifically limit the manner in which the third feed source 823 is electrically connected to the second radiator 821 .

[0088] As a way to achieve this, Figure 8 As shown, the second radiator 821 further includes a third feeding point G′, which is located between the second feeding point F′ and the second ground terminal H′, and the third feed source 823 is electrically connected to the second radiator 821 via the third feeding point G′.

[0089] The embodiment of the present application does not specifically limit the form of the first feeding point E', the second feeding point F' or the third feeding point G'. For example, the first feeding point E', the second feeding point F' or the third feeding point G' may be a welding point or a conductive spring or conductive glue.

[0090] As another implementation, Fig.19 As shown, the third feed source 823 is connected to the second radiator 821 through the second feed point F'. That is, the third feed source 823 shares the second feed point F' with the second feed source 822. By sharing the feed point, the setting of one feed point can be saved, the wiring of the antenna assembly 80 can be reduced, and the space cost and design cost can be reduced.

[0091] For ease of understanding, the following is combined with Figure 9- Fig.12 The operating frequency band and corresponding operating mode of the antenna assembly 80 are exemplarily described.

[0092] In some embodiments, the first target frequency band may include a WIFI 5G frequency band. Accordingly, the antenna ANT1 corresponding to the first feed source has a first resonance mode, and the first resonance mode may include a first sub-resonance mode-a third sub-resonance mode supporting the WIFI 5G frequency band.

[0093] As shown by the arrowed line in FIG9(a), the first sub-resonance mode is a 1 / 4 wavelength mode from the first feed source 812 to the slot 83. As shown by the arrowed line in FIG9(b), the second sub-resonance mode is a three-quarter wavelength mode from the second ground terminal GND2' to the slot 83, and there is a strong unidirectional current passing through the slot 83 to the first feed source 812. As shown by the arrowed line in FIG9(c), the third sub-resonance mode is a three-quarter wavelength mode from the second ground terminal GND2' to the slot 83, and there is a strong reverse current passing through the slot 83 to the first feed source 812.

[0094] In some embodiments, the first target frequency band or the second target frequency band may further include a UHB frequency band. The UHB frequency band may include an N78 frequency band and an N77 frequency band, respectively. The N78 frequency band is a 3.4-3.6 GHz frequency band, and the N77 frequency band is a 3.3-4.2 GHz frequency band. Accordingly, the antenna ANT1' corresponding to the first feed source or the antenna ANT2' corresponding to the second feed source has a sixth sub-resonance mode and a seventh sub-resonance mode for supporting the UHB frequency band.

[0095] FIG9(d) and FIG9(e) show schematic diagrams of the paths of the resonant current when the antenna ANT1' corresponding to the first feed source has the sixth sub-resonance mode and the seventh sub-resonance mode for supporting the UHB band when the first target frequency band includes the UHB band. Specifically, as shown by the arrowed line in FIG9(d), the sixth sub-resonance mode is a quarter-wavelength mode from the first ground terminal D' to the slot 83, and there is (or is said to be accompanied by) a strong unidirectional current passing through the slot 83 to the second feed source 822. As shown by the arrowed line in FIG9(e), the seventh sub-resonance mode is a quarter-wavelength mode from the first ground terminal D' to the slot 83, and there is a strong reverse current passing through the slot 83 to the second feed source 822.

[0096] It should be understood that the sixth sub-resonance mode and the seventh sub-resonance mode constitute an EE radiation mode and a balanced mode. The second sub-resonance mode and the third sub-resonance mode constitute an EE higher-order radiation mode and a balanced mode.

[0097] like Fig.10 The following is a simulation diagram of the S parameters and efficiency of antenna ANT1. The UHB band can be Fig.10 The mark points 1 and 2 in the figure indicate that the WIFI5G frequency band can be Fig.10The marked points 3-5 in the diagram represent the frequency of the marked point 1, which is 3.0972 GHz and the radiation efficiency is -9.9035 dB; the frequency of the marked point 2 is 3.9999 GHz and the radiation efficiency is -33.587 dB; the frequency of the marked point 3 is 5.1976 GHz and the radiation efficiency is -7.8795 dB; the frequency of the marked point 1 is 5.5103 GHz and the radiation efficiency is -7.654 dB; the frequency of the marked point 1 is 5.7935 GHz and the radiation efficiency is -24.769 dB. Fig.10 It can be seen that due to the high efficiency of the high-order mode, high working efficiency is achieved in the 3-6G band, achieving ultra-wideband coverage.

[0098] In some embodiments, the second target frequency band may include the GPS-L1 frequency band and the WIFI2.4G frequency band. Correspondingly, the antenna ANT2' corresponding to the second feed source has a second resonance mode, and the second resonance mode is used to support the reception or transmission of the second target frequency band. Specifically, the second resonance mode includes a fourth sub-resonance mode and an eighth sub-resonance mode. The fourth sub-resonance mode is used to support the first navigation frequency band, and the eighth sub-resonance mode is used to support the WIFI2.4G frequency band.

[0099] As shown by the arrowed line in FIG11(a), the fourth sub-resonance mode is a quarter-wavelength mode from the second ground terminal GND2' to the slot 83. As shown by the arrowed line in FIG11(b), the eighth sub-resonance mode is a quarter-wavelength mode from the first ground terminal GND1' to the slot 83, and there is a weaker unidirectional current passing through the slot to the second feed source 822.

[0100] like Fig.12 As shown, it is a simulation diagram of the S parameters and efficiency of the antenna ANT2'. Among them, the first navigation frequency band (such as GPS-L1 frequency band) is represented by the marked point 1, and the WIFI2.4G frequency band is represented by the marked point 2. Among them, the frequency of the marked point 1 is 1.5632GHz, and the radiation efficiency is -17.641dB; the frequency of the marked point 2 is 2.4718GHz, and the radiation efficiency is -21.296dB.

[0101] The antenna assembly in the embodiment of the present application generates a navigation frequency band through a second radiator located on the top wall of the electronic device and a second feed source connected to the second radiator. Therefore, the receiving point of the navigation signal avoids the user's hand grip, thereby avoiding the phenomenon of a sudden drop in the radiation efficiency of the navigation frequency band caused by the user's grip, and effectively improving the navigation performance of the antenna assembly. As mentioned above, the third target frequency band includes the second navigation frequency band. Correspondingly, the antenna ANT3' corresponding to the third feed source 723 has a third resonant mode, and the third resonant mode includes a fifth sub-resonant mode for supporting the reception or transmission of the second navigation frequency band.

[0102] In the embodiment of the present application, the fifth sub-resonance mode is also a quarter-wavelength mode from the second ground terminal GND2' to the gap 83 as shown in FIG11(a). That is, the path of the resonant current corresponding to the fifth sub-resonance mode is the same as the path of the resonant current corresponding to the fourth sub-resonance mode.

[0103] Combination Fig.13 As shown, it is the simulation diagram of the S parameters and efficiency of the antenna ANT3'. Fig.13 In the figure, the second navigation frequency band is the GPS-L5 frequency band, and the GPS-L5 frequency band is indicated by the marked point 1. The frequency of the marked point 1 is 1.1679 GHz, and the radiation efficiency is -14.159 dB.

[0104] Since the paths of the resonant current used to support the first navigation frequency band and the second navigation frequency band are the same, in order to ensure the radiation power of the first navigation frequency band and the second navigation frequency band, such as Figure 8 As shown, a third matching circuit M3' may be further provided between the third feed 823 and the second radiator 821. The third matching circuit M3' is used to filter out the clutter of the excitation signal transmitted by the third feed 823 to isolate the first navigation frequency band and the second navigation frequency band, so that the quarter-wavelength mode from the second ground terminal GND2' to the slot 83 resonates in the second navigation frequency band. In addition, the third matching circuit M3' is also used to perform impedance matching on the excitation signal transmitted by the third feed 823 to excite the quarter-wavelength mode from the second ground terminal GND2' to the slot 83 to resonate in the second navigation frequency band.

[0105] It can be seen from this that although the resonance mode corresponding to the second navigation frequency band is the same as the resonance mode corresponding to the first navigation frequency band, the third matching circuit M3' can have a strong regulating effect on the resonance mode corresponding to the second navigation frequency band. Therefore, by setting the third matching circuit M3', it can be isolated and distinguished from the first navigation frequency band.

[0106] Optionally, a first matching circuit M1' may be provided between the first feed source 812 and the first feeding point E'. The first matching circuit M1' may be used to filter out clutter of the excitation signal transmitted by the first feed source 812, and may also be used to perform impedance matching on the excitation signal transmitted by the first feed source to excite the first radiator and / or the second radiator to resonate in the first target frequency band.

[0107] Optionally, a second matching circuit M2' may be provided between the second feed source 822 and the second feeding point F'. The second matching circuit M2' may be used to filter out the clutter of the excitation signal transmitted by the second feed source 822, and may also be used to perform impedance matching on the excitation signal transmitted by the second feed source to excite the second radiator and / or the first radiator to resonate in the second target frequency band.

[0108] In some embodiments, the first matching circuit M1 ′, the second matching circuit M2 ′, and the third matching circuit M3 ′ may have a filtering function and an impedance matching function as well as an isolation function between frequency bands.

[0109] The embodiment of the present application does not specifically limit the structure of the first matching circuit M1', the second matching circuit M2' or the third matching circuit M3'. M1', M2' or M3' may include but are not limited to frequency-selective filtering networks such as capacitors, inductors, resistors, etc. arranged in series and / or in parallel. In some embodiments, M1', M2' or M3' may include branches formed by multiple capacitors, inductors, and resistors connected in series and / or in parallel, and switches for controlling the on and off of multiple branches. By controlling the on and off of different switches, the frequency-selective parameters of the matching circuit (such as resistance value, inductance value and capacitance value) can be adjusted, and then the filtering range of the matching circuit can be adjusted, so that the matching circuit can adjust the corresponding radio frequency signal. Different matching circuits may be different, and their specific circuit implementations are not used to limit the scope of protection of the present application. The matching circuits are all used to adjust the impedance of the radiator to which they are electrically connected, so that the impedance of the radiator to which they are electrically connected matches the frequency at which it resonates, thereby achieving a larger receiving and transmitting power of the radiator. By setting a matching circuit and adjusting the parameters of the frequency modulation circuit, the resonant frequency of each antenna can be moved along the low frequency or high frequency, thereby achieving ultra-wideband of the antenna assembly 80 and increasing the coverage and communication quality of the antenna signal of the antenna assembly 80.

[0110] For example, the structure of the first matching circuit M1', the second matching circuit M2' or the third matching circuit M3' may be as follows: Fig.14 As shown. Among them, Fig.14 (a) includes a first inductor L1 and a first capacitor C1 connected in series; Fig.14 (b) includes a first inductor L1 and a first capacitor C1 connected in parallel; Fig.14 (c) includes a second capacitor C2 connected in series with the first inductor L1 and the first capacitor C1 connected in parallel; Fig.14 (d) includes a second inductor L2 connected in series with the first inductor L1 and the first capacitor C1 connected in parallel; Fig.14 (e) includes a second capacitor C2 connected in parallel with the first inductor L1 and the first capacitor C1 connected in series; Fig.14 (f) includes a second inductor L2 connected in parallel with the first inductor L1 and the first capacitor C1 connected in series; Fig.14 (g) includes a second inductor L2 and a second capacitor C2 connected in series with the first inductor L1 and the first capacitor C1 connected in parallel, wherein the second inductor L2 and the second capacitor C2 are connected in parallel; Fig.14(h) includes a second inductor L2 and a second capacitor C2 connected in parallel with the first inductor L1 and the first capacitor C1 connected in series, wherein the second inductor L2 and the second capacitor C2 are connected in series. It should be understood that the structure of the first matching circuit M1', the second matching circuit M2' or the third matching circuit M3' is not limited to Fig.14 The structure shown may also include switches or other impedance adjustment elements.

[0111] In order to verify the working efficiency of the antenna assembly 80, Fig.15 Simulation diagrams of S parameters of the antenna ANT1 ′ corresponding to the first feed source in the antenna assembly 80 , the antenna ANT2 ′ corresponding to the second feed source 822 , and the antenna ANT3 ′ corresponding to the third feed source 823 are given. Fig.16 Simulation diagrams of the system radiation efficiency and the system total efficiency of the antenna ANT1 ′ corresponding to the first feed source in the antenna assembly 80 , the antenna ANT2 ′ corresponding to the second feed source 822 , and the antenna ANT3 ′ corresponding to the third feed source 823 are given.

[0112] like Fig.15 As shown, the frequency points generated by the excitation of antenna ANT1' include frequency points 2 to 6. Among them, the frequency of frequency point 2 is 3.1063GHz, and the return loss is -9.881dB; the frequency of frequency point 3 is 4GHz, and the return loss is -33.534dB; the frequency of frequency point 4 is 5.2004GHz, and the return loss is -7.877dB; the frequency of frequency point 5 is 5.5024GHz, and the return loss is -7.6501dB; the frequency of frequency point 6 is 5.7886GHz, and the return loss is -24.405dB. The frequency points generated by the excitation of antenna ANT2' include frequency points 7-8. Among them, the frequency of frequency point 7 is 1.5633GHz, and the return loss is -17.549dB; the frequency of frequency point 8 is 2.4714GHz, and the return loss is -21.267dB. The frequency point generated by the excitation of the antenna ANT3' is frequency point 1, the frequency of frequency point 1 is 1.1679 GHz, and the return loss is -14.159 dB.

[0113] like Fig.16As shown, the frequency points generated by the excitation of antenna ANT1' include frequency points 2-4. Among them, the frequency of frequency point 2 is 3.5079GHz, the total system efficiency is -2.8759dB, the frequency of frequency point 3 is 5.2687GHz, the total system efficiency is -3.3078dB; the frequency of frequency point 4 is 5.7009GHz, and the total system efficiency is -3.4689dB. The frequency points generated by the excitation of antenna ANT2' include frequency points 5-6. Among them, the frequency of frequency point 5 is 1.56GHz, the total system efficiency is -4.305dB, the frequency of frequency point 6 is 2.449GHz, and the total system efficiency is -3.0182dB. The frequency point generated by the excitation of antenna ANT3' is frequency point 1, the frequency of frequency point 1 is 1.18GHz, and the total system efficiency is -6.3786dB. It can be seen that the total system efficiency of the first target frequency band excited by antenna ANT1' is between -2dB and -4dB, and the radiation efficiency is relatively high. The total system efficiency of the second target frequency band excited by the antenna ANT2' is between -3dB and -5dB, and the radiation efficiency is also high. Meanwhile, the total system efficiency of the LB frequency band excited by the antenna ANT3' is about -6dB, and the radiation efficiency is also high.

[0114] pass Fig.15 and Fig.16 It can be seen that after the GPS-L5 band is merged into the branch of the GPS-L1 band in the antenna assembly 80 through the solution of the embodiment of the present application, the original bands such as WIFI2.4G, WIFI5G, and N78 can still be retained, and their radiation efficiency is not reduced. At the same time, the performance of the GPS-L1 band and the GPS-L5 band in the free scene are also retained. In addition, since the second radiator 821 that realizes the GPS-L5 band and the GPS-L1 band is located on the top wall of the electronic device 20, that is, the lateral short side, the influence of the user's grip on the navigation band can be avoided. This advantage is particularly prominent in the foldable electronic device 20, and the good performance of closed-cover calls and closed-cover navigation can be maintained in the scene of holding the cover after closing. Since the GPS-L1 band and the GPS-L5 band cannot be held dead, the performance in the closed scene is realized, which is beneficial to ensure the function of closed-cover navigation.

[0115] In addition, since the paths of the resonant currents corresponding to the GPS-L1 band and the GPS-L5 band in the embodiment of the present application are the same, both the GPS-L1 band and the GPS-L5 band can have a very high upper hemisphere share, thereby further ensuring the navigation communication performance.

[0116] In order to verify the upper hemisphere proportion of the GPS-L1 band and the GPS-L5 band in the antenna assembly 80, Fig.17 and Fig.18Simulation diagrams of the upper hemisphere proportions of the GPS-L1 frequency band and the GPS-L5 frequency band in the antenna assembly 80 are respectively given.

[0117] like Fig.17 As shown, the total 3D radiation efficiency of the GPS-L1 band is 0.031375839dB, the 3D radiation efficiency of the upper hemisphere is 0.017263043dB, and the 3D radiation efficiency of the lower hemisphere is 0.014112797dB. Therefore, the upper hemisphere of the GPS-L1 band accounts for 55%, so the upper hemisphere of the GPS-L1 band accounts for a high proportion.

[0118] like Fig.18 As shown, the total 3D radiation efficiency of the GPS-L5 band is 0.011611791dB, the 3D radiation efficiency of the upper hemisphere is 0.0060605275dB, and the 3D radiation efficiency of the lower hemisphere is 0.0055512635dB. Therefore, the upper hemisphere share of the GPS-L5 band is 52%, and it also has an upper hemisphere share of more than 50%. Therefore, the upper hemisphere share of the GPS-L5 band is also high.

[0119] The embodiment of the present application further provides an electronic device 20, and the antenna assembly 80 can be applied to the electronic device 20, that is, the electronic device 20 includes any of the antenna assemblies 80 described above.

[0120] The embodiment of the present application does not specifically limit the type of electronic device 20, as long as the electronic device 150 needs to implement wireless communication function through the antenna assembly. The electronic device can be, for example, a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA) device, a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a learning machine or an electronic dictionary and a smart watch and other terminal devices. Preferably, the electronic device is a foldable electronic device. For example, the electronic device can be an electronic device that can be folded vertically up and down to form a small screen. The folded small screen can also be called a secondary screen.

[0121] Taking the electronic device 20 as a mobile phone as an example, Fig. 20 and Fig.21 Schematic diagram of the layout of the antenna assembly 80 in the electronic device in the embodiment of the present application. It should be understood that Fig. 20 and Fig.21 For illustration only, the electronic device 20 may include multiple antenna assemblies 80 .

[0122] like Fig. 20 and Fig.21 As shown, the electronic device 20 may include a top wall 21 and side walls 22 located on both sides of the top wall.

The first side wall 221 and the second side wall 222 are areas for gripping. The first radiator 811 is arranged to extend from the top wall 21 of the electronic device 20 to the side wall 221 of the electronic device 20, and the second radiator 821 is arranged on the top wall 21 of the electronic device. This can prevent the signal of the antenna assembly 80 from being blocked when the user holds the electronic device 20.

The machine-readable storage medium can be any available medium that a computer can access or a data storage device such as a server or data center that includes one or more available media integrations.
