[0050] It should be noted that the concepts such as "first" and "second" mentioned in the present disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.
[0051] It should be noted that the modifications of "one" and "multiple" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more". The present disclosure is described below in conjunction with specific embodiments.
[0052] First, the application scenario of the present disclosure is explained. One of the difficulties brought about by the introduction of the SAR detection scheme to the antenna design is that the SAR detection needs to identify the scene by detecting the change of the capacitance to the ground, so its detection pad cannot be grounded, and there cannot be a rib between the antennas on both sides of the top of the mobile terminal. The currents on both sides affect each other, resulting in a sharp deterioration in the performance of the antennas on both sides. In the mobile terminals currently on the market, while using the suspended metal on the top of the mobile terminal for SAR detection, a GPSL5 antenna will be made in this place, but the feeding end of this antenna will have a relatively large impact on the performance of the opposite antenna due to the need for matching and tuning. Therefore, how to ensure the normal performance of the SAR detection function and ensure that the GPSL5 antenna is also on the top of the mobile terminal, while ensuring the optimal performance of other antennas is a relatively large design challenge.
[0053] Figure 1 is a schematic diagram of the structure of a conventional multi-band antenna involved in an embodiment of the present disclosure, such as Figure 1 As shown, the antenna includes: a metal frame as an antenna radiator (as shown by the black frame in the figure, the metal frame can be the middle frame of the mobile terminal, so the black frame can be understood as a cross-sectional view obtained by sectioning the middle frame of the mobile terminal in a direction parallel to the screen of the mobile terminal), and antennas ANT1-ANT5. The central metal suspension arm located at the top of the mobile terminal serves as the sensing antenna of the SAR detection solution. At the same time, a GPSL5 antenna (ANT3) is arranged on this suspended metal arm. The GPSL5 antenna (ANT3) utilizes the central metal suspension arm in the middle for radiation. The GPSL1+WIFI2.4 (ANT1) and WIFI6e (ANT2) antennas are designed in the same metal frame, and the MHB (ANT4) and N78+N79 (ANT5) are designed in the other side of the metal frame. According to Figure 1In the orientation shown in , ANT1, ANT2, ANT4, and ANT5 are respectively arranged on the left and right sides of the metal frame. Therefore, in this solution, since the feeding point of the GPSL5 antenna will be on the opposite side of at least one of the antennas ANT1, ANT2, ANT4, and ANT5, its matching capacitor will have a great impact on the performance of the antenna on the opposite side. In addition, a common problem of this solution is that the side to which the GPSL5 antenna is fed will affect the performance of the antenna on the same side, and its matching method will have a great impact on the current mode of the antenna on the same side. Generally speaking, the larger the first-level ground capacitance of the GPSL5 antenna, the better the performance of the antenna on the same side. However, due to the need to take into account the matching of the GPSL5 antenna, this capacitance has certain limitations and generally does not exceed 5pF. And the capacitance C on the other side is generally required to be above 33pF, which will have certain limitations on the compensation capacitance of the SAR (Specific Absorption Rate) sensor chip, resulting in a decrease in the degree of freedom of SAR index debugging and difficulty in debugging. Therefore, the applicant takes into account that the size of the metal frame of the current mobile terminal is certain. In order to reduce the difficulty of debugging the SAR index, in the embodiment of the present disclosure, GPSL1, WIFI2.4, B32 and N75 are synthesized on ANT1, WIFI6e and GPSL5 are synthesized on ANT2, and the central metal suspension arm is used alone as a SAR sensing antenna. This can increase the degree of freedom of SAR index debugging and reduce the difficulty of SAR index debugging. At the same time, it can also reduce the area of a shrapnel and matching circuit on the PCB (Printed Circuit Board) to achieve the purpose of miniaturization and multi-band antenna. While realizing the centralized miniaturization of the antenna, the matching circuit is reduced, and the saved PCB area adds more possibilities for the realization of other functions of the mobile terminal. The antenna assembly provided by the present disclosure is described below.
[0054] Figure 2 FIG. 1 is a schematic diagram showing the structure of an antenna assembly according to an exemplary embodiment. Figure 2 As shown, the embodiment of the present disclosure provides an antenna assembly, including: a first antenna branch 1, the first antenna branch 1 includes a first feed point 2 and a second feed point 4; the first feed point 2 is used to connect to a first feed source 3 to excite the first antenna branch 1 to receive and transmit a first GPS frequency band signal and a first wifi frequency band signal; the second feed point 4 is used to connect to a second feed source 5 to excite the first antenna branch 1 to receive and transmit a second GPS frequency band signal and a second wifi frequency band signal. Exemplarily, the first GPS frequency band may be GPSL1, the first wifi frequency band may be WIFI2.4, the second GPS frequency band may be GPSL5, and the second wifi frequency band may be WIFI6e.
[0055] In summary, the embodiment of the present disclosure provides an antenna assembly, including: a first antenna branch, the first antenna branch including a first feed point and a second feed point; the first feed point is used to connect to a first feed source to excite the first antenna branch to receive and transmit a first GPS frequency band signal and a first wifi frequency band signal; the second feed point is used to connect to a second feed source to excite the first antenna branch to receive and transmit a second GPS frequency band signal and a second wifi frequency band signal. The embodiment of the present disclosure realizes multi-band fusion in the same antenna branch by merging the first GPS frequency band signal and the first wifi frequency band signal as well as the second GPS frequency band signal and the second wifi frequency band signal in the first antenna branch, thereby realizing antenna miniaturization and multi-band design.
[0056] In some embodiments, the first feed source 3 is also used to excite the first antenna branch 1 to transmit and receive low-frequency band signals; and / or, the first feed source 3 is also used to excite the first antenna branch 1 to transmit and receive first 5G band signals. Exemplarily, the low-frequency band may be B32, and the first 5G band may be N75.
[0057] In some embodiments, a first matching circuit is provided between the first feed point 2 and the first feed source 3 ; and a second matching circuit is provided between the second feed point 4 and the second feed source 5 .
[0058] In summary, the disclosed embodiment integrates the four frequency bands of GPSL1, WIFI2.4, B32, and N75, and the two frequency bands of GPSL5 and WIFI6e on the first antenna branch, which can reduce the area of a spring and a matching circuit on the PCB, thereby achieving the purpose of miniaturization and multi-band antenna. While achieving centralized miniaturization of the antenna, the matching circuit is reduced, and the saved PCB area increases the possibility of realizing other functions of the mobile terminal.
[0059] Figure 3 FIG. 1 is a schematic diagram of a first antenna matching circuit according to an exemplary embodiment. Figure 3 As shown, the first matching circuit includes: a primary matching module M1, which is used to achieve matching of the first WiFi frequency band signal and isolate the second WiFi frequency band signal; a secondary matching module M2, which is used to achieve matching of the first GPS frequency band signal.
[0060] In some embodiments, the primary matching module M1 includes: a first feed point first stage inductor 6 connected in series between the first feed point 2 and the first feed source 3 and a first feed point first stage capacitor 7 connected in parallel between the first feed point 2 and the ground.
[0061] In some embodiments, the secondary matching module M2 includes: a first feed point second-stage capacitor 8 connected in series between the first feed point 2 and the first feed source 3 and a first feed point second-stage inductor 9 connected in parallel between the first feed point 2 and the ground. Exemplarily, in the matching process, in order to take into account the performance of N75 and B32, the capacitance of the first feed point second-stage capacitor 8 can be appropriately increased to increase the bandwidth.
[0062] To sum up, the embodiment of the present disclosure first utilizes the parallel connection of the first-level capacitor of the first feed point and the series connection of the first-level inductor of the first feed point to match WIFI2.4, and at the same time realizes the isolation of WIFI6e. The first-level capacitor of the first feed point here can pull the low-efficiency high-order mode of WIFI6e out of the band; then utilizes the parallel connection of the second-level inductor of the first feed point and the series connection of the second-level capacitor of the first feed point to match GPSL1+B32+N75.
[0063] Figure 4 FIG. 1 is a schematic diagram of a second antenna matching circuit according to an exemplary embodiment. Figure 4 As shown, the second matching circuit includes: a three-level matching module M3, which is used to match the second GPS frequency band signal and isolate the low-frequency band signal; a four-level matching module M4, which is used to match the second wifi frequency band signal; a five-level matching module M5, which is used to isolate the first wifi frequency band signal and further match the second wifi frequency band signal.
[0064] In some embodiments, the three-stage matching module M3 includes: a second feed point first-stage capacitor 10 connected in series between the second feed point 4 and the second feed source 5 and a second feed point first-stage inductor 11 connected in parallel between the second feed point 4 and the ground.
[0065] In some embodiments, the four-stage matching module M4 includes: a second-feed-point second-stage capacitor 12 connected in parallel between the second feed point 4 and the ground.
[0066] In some embodiments, the five-stage matching module M5 includes: a second feed point third-stage capacitor 13 and a second feed point third-stage inductor 14 connected in parallel between the second feed point 4 and the second feed source 5 .
[0067] To sum up, compared with the traditional solution, the first antenna branch of the embodiment of the present invention needs to integrate GPSL5 on the basis of WIFI6e, so through the first-level matching: the first-level capacitor of the second feed point is connected in series and the first-level inductor of the second feed point is connected in parallel to match GPSL5, and also serves as a low-frequency isolation to isolate the low frequency of the first feed point; the second-level capacitor of the second feed point in parallel in the last stage is matched for WIFI6e; in the last stage, the third-level capacitor of the second feed point is connected in parallel with the third-level inductor of the second feed point, on the one hand, to isolate WIFI2.4 from the first feed point, and on the other hand, the third-level inductor of the second feed point matches WIFI6e, and the capacitance of the third-level capacitor of the second feed point can be selected to be a slightly larger value, which has less impact on WIFI6e.
[0068] In some embodiments, the four-stage matching module M4 includes: a second-stage inductor 15 of a second feeding point connected in parallel between the second feeding point 4 and the ground, used for fine-tuning the matching between the second GPS frequency band signal and the second WiFi frequency band signal.
[0069] In the embodiment of the present disclosure, according to the actual debugging situation, the second-stage inductor of the second feeding point can be connected in parallel behind the second-stage capacitor of the second feeding point. In this way, on the one hand, GPSL5 can be fine-tuned, and on the other hand, the circular position of WIFI6e can be fine-tuned.
[0070] like Figure 2 As shown, in some embodiments, one end of the first antenna branch 1 is grounded (not shown in the figure), and the other end is provided with a first break 16 , and the second feed point 4 is provided between the first feed point 2 and the first break 16 .
[0071] In some embodiments, the antenna assembly includes: a second antenna branch 17 , the second antenna branch 17 is disposed on the other side of the first slit 16 , and the second antenna branch 17 and the first antenna branch 1 are spaced apart.
[0072] In some embodiments, a metal branch 18 is provided between the first antenna branch 1 and the second antenna branch 17 , a first break 16 is provided between the metal branch 18 and the first antenna branch 1 , and a second break 19 is provided between the metal branch 18 and the second antenna branch 17 .
[0073] In some embodiments, the second antenna branch 17 includes a third feed point 20 and a fourth feed point 21. The third feed point 20 is used to connect to a third feed source 22 to stimulate the second antenna branch 17 to transmit and receive mid-high frequency band signals. Exemplarily, the mid-high frequency band may be NHB.
[0074] The fourth feed point 21 is used to connect the fourth feed source 23 to excite the second antenna branch 17 to send and receive the second 5G frequency band signal and the third 5G frequency band signal. Exemplarily, the second 5G frequency band may be N78, and the third 5G frequency band may be N79.
[0075] In some embodiments, the metal branch 18 is used to implement a SAR sensing antenna. A first specific absorption rate debugging capacitor 25 is connected in series between the first end 24 of the metal branch 18 and the ground, and a second specific absorption rate debugging capacitor 28 connected in series to the ground is connected to the second end 26 of the metal branch 18. For example, Figure 2 As shown, the larger the capacitance value of the first specific absorption rate debugging capacitor 25, the better the performance of the frequency band of the first feed point 2 and the frequency band of the second feed point 4. After the metal branch 18 is not used as the GPSL5 antenna, the capacitance value of the first specific absorption rate debugging capacitor 25 is not affected by the matching and can be freely selected, and the debugging freedom of the second specific absorption rate debugging capacitor 28 can be increased. The capacitance value of the second specific absorption rate debugging capacitor 28 on the other side can be selected according to the actual debugging situation. The larger the capacitance value of this second specific absorption rate debugging capacitor 28, the better the frequency band performance of the third feed point 20.
[0076] In summary, the disclosed embodiment uses the metal branch alone as a SAR sensing antenna. Compared with the traditional practice of using the metal branch as a GPSL5 antenna, which limits the matching capacitors on both sides and reduces the antenna performance, the disclosed embodiment can adjust the capacitance of the first specific absorption rate debugging capacitor and the second specific absorption rate debugging capacitor in a larger range, thereby increasing the degree of freedom of SAR index debugging and reducing the difficulty of SAR index debugging.
[0077] Figure 5 FIG. 1 is a schematic diagram of an antenna assembly including a de-isolation circuit according to an exemplary embodiment. Figure 5 As shown, the metal branch 18 is used to implement a SAR sensing antenna. A first specific absorption rate debugging capacitor 25 is connected in series between the first end 24 of the metal branch 18 and the ground, and a second end 26 of the metal branch 18 is connected to a SAR sensor 27 and a de-isolation circuit M6, which is used to de-isolate the first wifi frequency band signal from the mid-high frequency band signal.
[0078] In some embodiments, the de-isolation circuit M6 includes: a de-isolation inductor 29 and a de-isolation capacitor 30 connected in series to the ground. In this way, the first wifi frequency band signal and the medium and high frequency band signal can be de-isolated by the de-isolation circuit M6, thereby improving the isolation between the first feeding point frequency band and the third feeding point frequency band.
[0079] In summary, the disclosed embodiment uses the metal branch as a SAR sensing antenna alone, which is different from the traditional practice of using the metal branch as a GPSL5 antenna, which results in limited matching capacitors on both sides and reduced antenna performance. The disclosed embodiment can adjust the capacitance of the first specific absorption rate debugging capacitor and the second specific absorption rate debugging capacitor in a wider range, increase the degree of freedom of SAR index debugging, and reduce the difficulty of SAR index debugging. In addition, the first wifi frequency band signal and the medium and high frequency band signal are decoupled by the de-isolation circuit, thereby improving the isolation between the first feed point frequency band and the third feed point frequency band.
