[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0028] The antenna assembly according to an embodiment of the present utility model is described below with reference to the accompanying drawings. Figure 1-Figure 5 As shown, the antenna assembly according to the embodiment of the utility model includes a cellular antenna radiator 11, a sky antenna radiator 12, a metal part 13, a first switch circuit 14 and a second switch circuit 15. The metal part 13 is provided with a first grounding point 131, and the first grounding point 131 is adjacent to the sky antenna radiator 12. The first switch circuit 14 includes a plurality of tuning branches, and the second switch circuit 15 includes a plurality of tuning branches.

[0029] The antenna assembly has a cellular communication mode and a satellite communication mode. When the antenna assembly is in the cellular communication mode, the first switch circuit 14 and the second switch circuit 15 are isolated from each other, that is, the first switch circuit 14 is not electrically connected to the second switch circuit 15. When the antenna assembly is in the satellite communication mode, one end of one of the multiple tuning branches of the first switch circuit 14 is electrically connected to the cellular antenna radiator 11, the other end of the one of the multiple tuning branches of the first switch circuit 14 is electrically connected to one end of one of the multiple tuning branches of the second switch circuit 15, and the other end of the one of the multiple tuning branches of the second switch circuit 15 is electrically connected to the first grounding point 131.

[0030] That is, the cellular antenna radiator 11, a tuning branch of the first switch circuit 14, a tuning branch of the second switch circuit 15, and the first grounding point 131 are electrically connected in sequence.

[0031] Theoretically, the radiation pattern of the Tiantong antenna radiator 12 is roughly spherical, but due to the influence of the shape of the electronic device, the radiation pattern of the Tiantong antenna radiator 12 will be distorted. Since the width of the foldable electronic device in the unfolded state is greater than that of the non-foldable electronic device, the distortion of the radiation pattern of the Tiantong antenna radiator of the foldable electronic device is more serious. From the simulation results, the radiation pattern of the Tiantong antenna radiator is distorted toward the direction of the adjacent cellular antenna radiator (such as Figure 7 shown).

[0032] According to the antenna assembly of the embodiment of the utility model, in the satellite communication mode, the cellular antenna radiator 11, a tuning branch of the first switch circuit 14, a tuning branch of the second switch circuit 15 and the first grounding point 131 are electrically connected in sequence, so that the cellular antenna radiator 11 and the metal part 13 can be connected together. In this way, the cellular antenna radiator 11 can be used to suppress the side lobe of the Tiantong antenna radiator 12 toward the cellular antenna radiator 11, and the metal part 13 can be used to suppress the side lobe of the Tiantong antenna radiator 12 toward the metal part 13, thereby improving the gain of the main lobe of the Tiantong antenna radiator 12, so as to improve the top performance of the Tiantong antenna radiator 12.

[0033] Therefore, the antenna assembly according to the embodiment of the utility model has the advantages of large main lobe gain of the Tiantong antenna radiator 12 and good top-to-bottom performance, thereby having excellent satellite communication performance.

[0034] The utility model also discloses an electronic device 100. The electronic device 100 according to the embodiment of the utility model can be a mobile phone, a tablet computer, a notebook computer, etc. Figure 1-Figure 6 As shown, the electronic device 100 according to the embodiment of the utility model comprises a first part 1 and a second part 2, and the first part 1 and the second part 2 are relatively rotatably arranged so that the electronic device 100 has a folded state and an unfolded state, that is, the electronic device 100 is a foldable electronic device.

[0035] When the electronic device 100 is in the unfolded state, the first part 1 and the second part 2 are arranged along a first direction. For example, when the electronic device 100 is in the unfolded state, the first part 1 and the second part 2 are arranged along the width direction of the first part 1 (the width direction of the second part 2).

[0036] The first part 1 includes an antenna assembly, which has a cellular communication mode and a satellite communication mode. The antenna assembly includes a cellular antenna radiator 11, a skycomb antenna radiator 12, a metal part 13, a first switch circuit 14 and a second switch circuit 15.

[0037] Optionally, the first part 1 includes a middle frame assembly, and the middle frame assembly includes a cellular antenna radiator 11 and a sky antenna radiator 12 of the antenna assembly. For example, the metal frame of the middle frame assembly includes the cellular antenna radiator 11 and the sky antenna radiator 12 of the antenna assembly. That is, the sky antenna of the electronic device 100 is a built-in antenna.

[0038] like Figure 1 As shown, the cellular antenna radiator 11 is located between the Tiantong antenna radiator 12 and the second portion 2 in the first direction, that is, the cellular antenna radiator 11 is adjacent to the second portion relative to the Tiantong antenna radiator 12 in the first direction. For example, the first direction is consistent with the left-right direction, and the cellular antenna radiator 11 is located on the right side of the Tiantong antenna radiator 12.

[0039] The first part 1 also includes a camera assembly, and the camera assembly includes a metal part 13 of an antenna assembly. Optionally, the metal part 13 is a camera decorative metal part.

[0040] The metal part 13 is provided with a first grounding point 131 and a second grounding point 132. When the cellular antenna radiator 11 is working, the magnetic field of the cellular antenna radiator 11 will be coupled to the metal part 13, resulting in a coupling current on the metal part 13, thereby reducing the performance of the cellular antenna radiator 11. By providing the first grounding point 131 and the second grounding point 132 on the metal part 13, the coupling current on the metal part 13 can be returned to the ground through the first grounding point 131, thereby effectively suppressing the influence of the metal part 13 on the cellular antenna radiator 11.

[0041] In order to further suppress the influence of the metal member 13 on the cellular antenna radiator 11, a third grounding point 133, a fourth grounding point 134 and a fifth grounding point 135 may be provided on the metal member 13. Thus, even if the metal member 13 is close to the cellular antenna radiator 11 (for example, the distance between the metal member 13 and the cellular antenna radiator 11 in the length direction of the first portion 1 is less than or equal to 10 mm), the influence of the metal member 13 on the cellular antenna radiator 11 can be effectively suppressed.

[0042] The first grounding point 131 and the second grounding point 132 are both adjacent to the radiator 12 of the Tiantong antenna. Figure 1As shown, the first grounding point 131 and the second grounding point 132 are adjacent to the radiator 12 of the sky antenna in the length direction of the first part 1. Further optionally, the first grounding point 131 and the second grounding point 132 are adjacent to the radiator 12 of the sky antenna in the length direction and / or width direction of the first part 1 relative to the third grounding point 133, the fourth grounding point 134 and the fifth grounding point 135. The length direction of the first part 1 is as shown in FIG. Figure 1 As shown by arrow A in FIG. 1 , the width direction of the first portion 1 is as follows Figure 1 As shown by arrow B in FIG.

[0043] The first switch circuit 14 includes a plurality of tuning branches, and the second switch circuit 15 includes a plurality of tuning branches. When the antenna assembly is in the cellular communication mode, the first switch circuit 14 and the second switch circuit 15 are isolated from each other. That is, when the antenna assembly is in the cellular communication mode, the cellular antenna radiator 11 and the metal member 13 are not electrically connected through a tuning branch of the first switch circuit 14 and a tuning branch of the second switch circuit 15.

[0044] like Figure 2 and Figure 5 As shown, the first switch circuit 14 includes a first tuning branch 141, a second tuning branch 142, a third tuning branch 143 and a fourth tuning branch 144. When the antenna assembly is in the cellular communication mode, the first tuning branch 141, the second tuning branch 142, the third tuning branch 143 and the fourth tuning branch 144 are switchably electrically connected between the cellular antenna radiator 11 and the ground. The first tuning branch 141, the second tuning branch 142, the third tuning branch 143 and the fourth tuning branch 144 are not electrically connected to each tuning branch of the second switch circuit 15.

[0045] When the antenna assembly is in the satellite communication mode, one end of one of the first tuning branch 141, the second tuning branch 142, the third tuning branch 143 and the fourth tuning branch 144 is electrically connected to the cellular antenna radiator 11, and the other end of the one of the first tuning branch 141, the second tuning branch 142, the third tuning branch 143 and the fourth tuning branch 144 is electrically connected to one end of the one of the multiple tuning branches of the second switch circuit 15. In other words, the one of the first tuning branch 141, the second tuning branch 142, the third tuning branch 143 and the fourth tuning branch 144 is not grounded.

[0046] Optionally, the first tuning branch 141 includes a first inductor, the second tuning branch 142 includes a second inductor, the third tuning branch 143 includes a first zero-ohm resistor, and the fourth tuning branch 144 includes a wire. When the antenna assembly is in a cellular communication mode, the first tuning branch 141, the second tuning branch 142, and the third tuning branch 143 are switchably electrically connected between the cellular antenna radiator 11 and the ground.

[0047] like Figure 3 and Figure 5 As shown, the second switch circuit 15 includes a fifth tuning branch 151, a sixth tuning branch 152, a seventh tuning branch 153 and an eighth tuning branch 154. When the antenna assembly is in the cellular communication mode, the fifth tuning branch 151 is electrically connected between the first grounding point 131 and the ground to improve the cellular communication performance of the antenna assembly. Each of the first tuning branch 141, the second tuning branch 142, the third tuning branch 143 and the fourth tuning branch 144 is not electrically connected to each of the fifth tuning branch 151, the sixth tuning branch 152, the seventh tuning branch 153 and the eighth tuning branch 154.

[0048] When the antenna assembly is in the satellite communication mode, one end of one of the sixth tuning branch 152, the seventh tuning branch 153 and the eighth tuning branch 154 is electrically connected to the first grounding point 131, and the other end of the one of the sixth tuning branch 152, the seventh tuning branch 153 and the eighth tuning branch 154 is electrically connected to the other end of the one of the first tuning branch 141, the second tuning branch 142, the third tuning branch 143 and the fourth tuning branch 144. In other words, the one of the sixth tuning branch 152, the seventh tuning branch 153 and the eighth tuning branch 154 is not grounded.

[0049] Optionally, the fifth tuning branch 151 includes a second zero-ohm resistor, the sixth tuning branch 152 includes a third inductor, the seventh tuning branch 153 includes a fourth inductor, and the eighth tuning branch 154 includes a first capacitor.

[0050] The following further describes the technical solution of the present application by taking the case where the cellular antenna radiator 11 is located on the right side of the Tiantong antenna radiator 12 and the metal part 13 is located below the Tiantong antenna radiator 12 as an example. When the metal part 13 is grounded, the directivity of the Tiantong antenna radiator 12 is not completely toward the top, but toward the right side, that is, toward the cellular antenna radiator 11.

[0051] By electrically connecting one of the sixth tuning branch 152, the seventh tuning branch 153 and the eighth tuning branch 154 to one of the first tuning branch 141, the second tuning branch 142, the third tuning branch 143 and the fourth tuning branch 144, the metal part 13 and the cellular antenna radiator 11 are electrically connected. Thus, the cellular antenna radiator 11 can be used to suppress the right side lobe of the Tiantong antenna radiator 12, and the metal part 13 can be used to suppress the downward side lobe of the Tiantong antenna radiator 12, thereby improving the gain of the main lobe of the Tiantong antenna radiator 12, so as to improve the top-to-top performance of the Tiantong antenna radiator 12 and take into account the cellular communication performance and satellite communication performance of the antenna assembly. The antenna assembly according to the embodiment of the utility model can especially improve the top-to-top performance and the gain of the main lobe of the Tiantong antenna radiator 12 of the foldable electronic device, thereby having excellent satellite communication performance.

[0052] Optionally, when the antenna assembly is in the satellite communication mode, at least another one of the first tuning branch 141, the second tuning branch 142, the third tuning branch 143, and the fourth tuning branch 144 is electrically connected between the cellular antenna radiator 11 and the ground. In other words, when the antenna assembly is in the satellite communication mode, the tuning branch of the first switch circuit 14 that is not electrically connected to the second switch circuit 15 can be electrically connected between the cellular antenna radiator 11 and the ground.

[0053] The inventor of the present application found during simulation and debugging that by adjusting the frequency of the resonance formed by the cellular antenna radiator 11 and the metal part 13 to be greater than the frequency of the sky-through antenna radiator 12, the cellular antenna radiator 11 can further suppress the side lobe of the sky-through antenna radiator 12 toward the cellular antenna radiator 11, and the metal part 13 can further suppress the side lobe of the sky-through antenna radiator 12 toward the metal part 13. In this way, the gain of the main lobe of the sky-through antenna radiator 12 can be further improved, and the top-to-top performance of the sky-through antenna radiator 12 can be further improved.

[0054] By electrically connecting at least one of the first tuning branch 141, the second tuning branch 142, the third tuning branch 143 and the fourth tuning branch 144 between the cellular antenna radiator 11 and the ground, the frequency of the resonance formed by the cellular antenna radiator 11 and the metal part 13 can be adjusted to be greater than the frequency of the Tiantong antenna radiator 12, so as to further improve the gain of the main lobe of the Tiantong antenna radiator 12 and the top-to-top performance of the Tiantong antenna radiator 12.

[0055] When the antenna assembly is in the satellite communication mode, at least another one of the sixth tuning branch 152, the seventh tuning branch 153 and the eighth tuning branch 154 is electrically connected between the first grounding point 131 and the ground. For example, the sixth tuning branch 152 is electrically connected to a tuning branch of the first switch circuit 14, and at least one of the seventh tuning branch 153 and the eighth tuning branch 154 is electrically connected between the first grounding point 131 and the ground.

[0056] By electrically connecting at least one of the sixth tuning branch 152, the seventh tuning branch 153 and the eighth tuning branch 154 between the first grounding point 131 and the ground, the frequency of the resonance formed by the cellular antenna radiator 11 and the metal part 13 can be adjusted to be greater than the frequency of the Tiantong antenna radiator 12, so as to further improve the gain of the main lobe of the Tiantong antenna radiator 12 and the top-to-top performance of the Tiantong antenna radiator 12.

[0057] For example, the frequency point of the Tiantong antenna radiator 12 is 2.2 GHz. Through different inductance / capacitance effects, the frequency of the resonance formed by the cellular antenna radiator 11 and the metal part 13 is adjusted to about 2.6G.

[0058] like Figure 1 As shown, the first grounding point 131 is adjacent to the cellular antenna radiator 11 in the first direction relative to the second grounding point 132. That is, the first grounding point 131 is located between the second grounding point 132 and the cellular antenna radiator 11 in the first direction.

[0059] like Figure 4 As shown, the antenna assembly further includes a third switch circuit 16, and the third switch circuit 16 includes a plurality of tuning branches. When the antenna assembly is in the cellular communication mode, one tuning branch of the third switch circuit 16 is electrically connected between the second grounding point 132 and the ground to improve the cellular communication performance of the antenna assembly. When the antenna assembly is in the satellite communication mode, at least another tuning branch of the third switch circuit 16 is electrically connected between the first grounding point 131 and the ground to further improve the gain of the main lobe of the radiator 12 of the sky antenna and the top-to-top performance of the radiator 12 of the sky antenna.

[0060] Thus, when the antenna assembly is in the satellite communication mode, at least another tuning branch of the third switch circuit 16 can be used to adjust the resonance generated by the metal member 13 itself, so as to adjust the frequency of the resonance generated by the metal member 13 itself to a frequency point greater than the frequency point of the radiator 12 of the Tiantong antenna. In addition, by electrically connecting at least another one of the sixth tuning branch 152, the seventh tuning branch 153 and the eighth tuning branch 154 between the first grounding point 131 and the ground, the resonance generated by the metal member 13 itself can also be adjusted.

[0061] For example, the frequency point of the Tiantong antenna radiator 12 is 2.2 GHz. Through the tuning branch of the first switch circuit 14 and the tuning branch of the second switch circuit 15, the frequency of the resonance generated by the metal part 13 itself can be adjusted to about 2.6G.

[0062] like Figure 4 As shown, the third switch circuit 16 includes a ninth tuning branch 161, a tenth tuning branch 162, an eleventh tuning branch 163 and a twelfth tuning branch 164. When the antenna assembly is in the cellular communication mode, the ninth tuning branch 161 is electrically connected between the second grounding point 132 and the ground to improve the cellular communication performance of the antenna assembly. When the antenna assembly is in the satellite communication mode, at least one of the tenth tuning branch 162, the eleventh tuning branch 163 and the twelfth tuning branch 164 is electrically connected between the first grounding point 131 and the ground to further improve the gain of the main lobe of the Tiantong antenna radiator 12 and the top-to-top performance of the Tiantong antenna radiator 12.

[0063] Optionally, the ninth tuning branch 161 includes a third zero-ohm resistor, the tenth tuning branch 162 includes a fifth inductor, the eleventh tuning branch 163 includes a sixth inductor, and the twelfth tuning branch 164 includes a second capacitor.
