[0098] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0099] This disclosure also provides an antenna structure. This antenna structure is applicable in scenarios where the frequency bands of multiple antennas intersect. For example, when the operating frequency bands of two adjacent antennas intersect, the antenna structure of this disclosure can be used so that when one of the two adjacent antennas is in operation, the other antenna can be adjusted to enable electromagnetic coupling between the two adjacent antennas. This reduces mutual interference between the two antennas and improves antenna efficiency.

[0100] Figure 1 This is a schematic diagram of an antenna structure according to an exemplary embodiment. Figure 1 .like Figure 1 As shown, the antenna structure 10 includes:

[0101] Multiple antennas 11 are arranged at intervals, and each antenna 11 is connected to a corresponding signal circuit 12;

[0102] The operating frequency bands of two adjacent antennas 11 are intersecting;

[0103] When one of the two adjacent antennas 11 is in operation, the circuit state of the signal circuit 12 connected to the other antenna 11 is adjusted so that the two adjacent antennas 11 can be electromagnetically coupled.

[0104] In this embodiment of the disclosure, the antenna structure is used to transmit and receive wireless signals, and can transmit and receive wireless communications such as Bluetooth (BT), WiFi, GPS, Universal Mobile Telecommunications System (UMTS), Long Term Evolution (LTE), and satellite communication.

[0105] The antenna structure described above includes multiple antennas spaced apart. That is, there is a gap between two adjacent antennas.

[0106] The aforementioned multiple antennas can be antennas with different functions. For example, multiple antennas may include mobile communication cellular antennas, GPS antennas, Wi-Fi antennas, BitTorrent antennas, or satellite antennas.

[0107] The present disclosure does not limit the location of the multiple antennas in the electronic device. For example, the multiple antennas can be located on different sides of the electronic device. As another example... Figure 2A As shown, multiple antennas 11 are all disposed on the top of the electronic device. The electronic device also includes a camera module 20, which, along with the multiple antennas, is disposed on the same side of the electronic device, specifically on its top.

[0108] The aforementioned multiple antennas can be of different types. For example, the multiple antennas may include frame antennas, laser-formed antennas, or circuit board antennas, etc., and this disclosure does not limit this.

[0109] The signal circuits connected to the aforementioned antenna may include a feed circuit, a matching circuit, and / or a tuning circuit, etc.

[0110] The feeding circuit is at least used to transmit feed energy to the antenna, enabling the antenna to transmit and receive wireless signals; the matching circuit is at least used to achieve impedance matching, so as to improve the transmission efficiency of feed energy and reduce signal reflection; and the tuning circuit is at least used to adjust the resonant frequency of the antenna.

[0111] In this embodiment of the disclosure, the operating frequency bands of two adjacent antennas among the plurality of antennas are interleaved. Here, if one adjacent antenna operates in the first frequency band and the second frequency band, and the other adjacent antenna operates in the second frequency band and the third frequency band, then the interleaved operating frequency band among the two adjacent antennas is the second frequency band.

[0112] For example, multiple antennas include a first antenna, a second antenna, and a third antenna. The second antenna can be an adjacent antenna to the first antenna, or it can be an adjacent antenna to the third antenna. That is, the operating frequency bands of the second antenna and the first antenna can intersect, or the operating frequency bands of the second antenna and the third antenna can intersect. In this embodiment of the present disclosure, when one of two adjacent antennas is in an active state, the circuit state of the signal circuit connected to the other antenna is adjusted.

[0113] It should be noted that the signal circuit corresponding to each antenna includes at least a switching module. Different switching states of the switching modules result in different circuit states for the corresponding signal circuits. Here, adjusting the circuit state of the signal circuit connected to another antenna may include adjusting the state of the switching module in the signal circuit connected to that other antenna.

[0114] In this embodiment of the disclosure, the circuit state of the signal circuit may include at least the state of whether the feed line connected to the antenna is grounded.

[0115] For example, when the switching module is in the off state, the feed line of the corresponding antenna is not grounded, which can directly transmit the feed energy to the antenna, thus enabling the antenna to work normally.

[0116] For example, when the switching module is in the ON state, the corresponding antenna feed line is grounded, causing the antenna to short-circuit to ground and thus malfunction. In this way, the antenna can electromagnetically couple with adjacent antennas due to their influence.

[0117] In this embodiment of the disclosure, when one antenna is in operation, another antenna receives electromagnetic energy from that antenna within the electromagnetic field range of the first antenna, and can jointly transmit and receive wireless signals based on this electromagnetic energy. This achieves electromagnetic coupling between two adjacent antennas.

[0118] It should be noted that electromagnetic coupling between two adjacent antennas can not only increase the transmission and reception efficiency of the working antenna, but also concentrate the energy of the working antenna to radiate in a specific direction, thereby improving the antenna's directivity.

[0119] In this embodiment, the operating frequency bands of two adjacent antennas intersect. When one antenna is operational, the circuit state of the signal circuit connected to the other antenna is adjusted to enable electromagnetic coupling between the two antennas. This allows one antenna to transmit and receive wireless signals simultaneously with the other, enhancing the antenna's radiation characteristics and reducing mutual interference caused by the intersecting operating frequency bands, thus improving antenna transmission and reception performance. Furthermore, the electromagnetic coupling between adjacent antennas concentrates energy radiation in a specific direction, improving the antenna's directivity.

[0120] For example, such as Figure 2A and Figure 2B As shown, multiple antennas 11 are all mounted on the top of the electronic device. Electromagnetic coupling between adjacent antennas allows energy to be concentrated in a vertical direction towards the top of the electronic device, i.e., the direction of arrow A.

[0121] In some embodiments, such as Figure 1 and Figure 3 As shown, the multiple antennas 11 include a first antenna 110, a second antenna 111, and a third antenna 112;

[0122] The second antenna 111 is spaced between the first antenna 110 and the third antenna 112;

[0123] When the second antenna 111 is in operation, the circuit state of the signal circuit connected to the first antenna 110 and / or the circuit state of the signal circuit connected to the third antenna 112 are adjusted.

[0124] When the second antenna 111 is in a non-operating state, if the first antenna 110 or the third antenna 112 is transmitting or receiving wireless signals, the circuit state of the signal circuit connected to the second antenna 111 is adjusted.

[0125] In this embodiment of the disclosure, the first antenna, the second antenna, and the third antenna can be different antennas. In some embodiments, the operating frequency band of the first antenna includes the GPS band and the Wi-Fi band; the operating frequency band of the second antenna includes the satellite band; and the operating frequency band of the third antenna includes the cellular band.

[0126] In other words, the first antenna may include a positioning antenna and a wireless fidelity antenna, the second antenna may include a satellite antenna, and the third antenna may include a mobile cellular antenna.

[0127] When the satellite antenna is in operation, the circuit state of the signal circuit of the mobile cellular antenna can be adjusted so that the mobile cellular antenna can be electromagnetically coupled with the satellite antenna, thereby reducing mutual interference between the mobile cellular antenna and the satellite antenna and improving the transmission and reception performance of the satellite antenna.

[0128] When the satellite antenna is in operation, the circuit states of the signal circuits of the positioning antenna and the wireless fidelity antenna can be adjusted so that both the positioning antenna and the wireless fidelity antenna can be electromagnetically coupled to the satellite antenna. This reduces the interference of the positioning antenna and the wireless fidelity antenna to the satellite antenna and improves the transceiver performance of the satellite antenna.

[0129] When the satellite antenna is not in operation, the circuit state of the satellite antenna's signal circuit can be adjusted so that the satellite antenna can electromagnetically couple with other adjacent antennas (such as cellular antennas, positioning antennas, and wireless fidelity antennas), thereby improving the transmission and reception performance of the other adjacent antennas.

[0130] In this embodiment of the disclosure, the positioning antenna may include a GPS L1 antenna with a center frequency of 1575MHz.

[0131] The aforementioned wireless fidelity antenna may include: a 2.4G Wi-Fi antenna and a 5G Wi-Fi antenna.

[0132] The aforementioned satellite antennas may include: Tiantong satellite antennas, Beidou satellite antennas, and Xingwang satellite antennas, etc. Here, the satellite antennas can cover the 1.5GHz to 2.5GHz frequency band.

[0133] The aforementioned mobile cellular antennas can cover the frequency bands from 1.71GHz to 5GHz, including: B1 band, B3 band, B40 band, B41 band, N78 band, N79 band, etc.

[0134] In this disclosure, the antenna structure can be applied to electronic devices. In some embodiments, such as... Figure 3 As shown, the first antenna 110, the second antenna 111, and the third antenna 112 are all located on the top of the electronic device.

[0135] In this embodiment of the disclosure, such as Figure 3As shown, the electronic device also includes a power module 40 and a volume module 30. The power module 40 is used to turn the electronic device's power on or off; the volume module 30 is used to adjust the volume of the audio output by the electronic device. Here, the power module 40, volume module 30, and the first antenna 110 can be located on the same side of the electronic device.

[0136] It should be noted that when the first, second, and third antennas are all located on the top of the electronic device, the three antennas will not be obstructed when the electronic device is held in the hand, thereby improving the transmission and reception performance of the three antennas.

[0137] In this embodiment of the disclosure, the second antenna being in a working state may include: using the second antenna for mobile communication. For example, the second antenna may be used for making calls, sending text messages, or accessing the Internet, etc., and this embodiment of the disclosure does not limit this.

[0138] The aforementioned second antenna being in a non-functional state may include: not using the second antenna for mobile communication. In this case, electronic devices with this antenna structure can use other antennas for mobile communication.

[0139] For example, the second antenna includes a satellite antenna, and the third antenna includes a mobile cellular antenna. In harsh outdoor environments, the second antenna can be used for mobile communication; however, in areas with mobile communication base station coverage, the third antenna can be used instead of the second antenna for mobile communication.

[0140] In this embodiment of the disclosure, the first antenna and the third antenna are adjacent antennas of the second antenna. When the second antenna is in operation, the circuit states of the signal circuit connected to the first antenna and the signal circuit connected to the third antenna can be adjusted simultaneously, or the circuit states of the signal circuit connected to the first antenna and the signal circuit connected to the third antenna can be adjusted independently.

[0141] It is understandable that when the second antenna is in operation, adjusting the circuit state of the signal circuit connected to the first antenna can enable electromagnetic coupling between the first and second antennas. This not only enhances the radiation characteristics of the second antenna but also reduces the interference of the first antenna on the second antenna, thereby improving the transmission and reception performance of the second antenna.

[0142] When the second antenna is in operation, adjusting the circuit state of the signal circuit connected to the third antenna can enable electromagnetic coupling between the third antenna and the second antenna. This not only enhances the radiation characteristics of the second antenna but also reduces the interference of the third antenna on the second antenna, thereby improving the transmission and reception performance of the second antenna.

[0143] In this embodiment of the present disclosure, when the second antenna is in a non-operational state, that is, when the second antenna is not working, if the first antenna is transmitting and receiving wireless signals, the circuit state of the signal circuit connected to the second antenna can be adjusted so that the second antenna can be electromagnetically coupled with the first antenna. This not only enhances the radiation characteristics of the first antenna, but also reduces the interference of the second antenna to the first antenna, thereby improving the transmission and reception performance of the first antenna.

[0144] If the third antenna is used for transmitting and receiving wireless signals, the circuit state of the signal circuit connected to the second antenna can be adjusted so that the second antenna can be electromagnetically coupled to the third antenna. This not only enhances the radiation characteristics of the third antenna but also reduces the interference of the second antenna to the third antenna, thereby improving the transmission and reception performance of the third antenna.

[0145] In some embodiments, such as Figure 3 and Figure 4 As shown, the signal circuit of the first antenna 110 includes:

[0146] The first feed 113 is connected to the first upper frame point I of the first antenna 110, and a first node is formed on the connection line between the first upper frame point I and the first feed 113.

[0147] The second feed 114 is connected to the second upper frame point II of the first antenna 110, and a second node is formed on the connection line between the second upper frame point II and the second feed 114.

[0148] The first switch module S1 is connected to the first node, the second node and the first grounding point 115;

[0149] When the second antenna 111 is in operation, the switching state of the first switching module S1 is adjusted so that the second antenna 111 and the first antenna 110 can be electromagnetically coupled.

[0150] In this embodiment of the disclosure, such as Figure 5 As shown, the horizontal axis represents frequency f, and the vertical axis represents return loss S11. The first antenna may include a 1.575G GPS antenna and a 2.4G Wi-Fi antenna, and the corresponding first feed source may include a feed source for the 1.575G GPS antenna and a feed source for the 2.4G Wi-Fi antenna. For example, when the first switch module disconnects the first node from the first grounding point, the first antenna transmits and receives wireless signals under the action of the first feed source.

[0151] like Figure 6 As shown, the horizontal axis represents the frequency f, and the vertical axis represents the return loss S11. The first antenna may also include a 5G Wi-Fi antenna, and the second feed source can be a feed source for the 5G Wi-Fi antenna. For example, when the first switch module disconnects the connection between the second node and the first grounding point, the first antenna transmits and receives wireless signals under the action of the second feed source.

[0152] In this embodiment of the present disclosure, a first gap is formed between the first antenna and the second antenna, and the second upper frame point can be located between the first upper frame point and the first gap. Thus, by setting the first upper frame point and the second upper frame point, the electromagnetic coupling between the first antenna and the second antenna can be better achieved by adjusting the switching state of the first switching module.

[0153] In this embodiment of the disclosure, such as Figure 4 As shown, the signal circuit of the first antenna 110 also includes a third impedance component 116 and a fourth impedance component 117. The third impedance component 116 is a connection line between the first node and the first upper frame point I; the fourth impedance component 117 is a connection line between the second node and the second upper frame point II.

[0154] It should be noted that the third and fourth impedance components can both be formed by cascading resistor components, capacitor components and / or inductor components.

[0155] For example, the third impedance component may include a first capacitor, and the fourth impedance component may include a second capacitor; the first capacitor is connected to the connection line between the first node and the first upper frame point; the second capacitor is connected to the connection line between the second node and the second upper frame point.

[0156] Here, the first capacitor and the second capacitor can be the same capacitor or they can be different capacitors.

[0157] In this embodiment of the disclosure, different switching states of the first switch module correspond to different grounding states of the first node and the second node. For example, adjusting the switching state of the first switch module can connect the first node to the first grounding point, thereby connecting the first upper frame point to the first grounding point; similarly, adjusting the switching state of the first switch module can connect the second node to the first grounding point, thereby connecting the second upper frame point to the first grounding point.

[0158] It is understandable that when the second antenna is in operation, adjusting the switching state of the first switching module enables electromagnetic coupling between the second antenna and the first antenna. This not only enhances the radiation characteristics of the second antenna but also reduces the interference of the first antenna on the second antenna, thereby improving the transmission and reception performance of the second antenna.

[0159] In some embodiments, such as Figure 4 As shown, the first feed 113 includes at least a feed for positioning;

[0160] If the first antenna 110 is in the positioning working state, the first upper frame point I is disconnected from the first ground point 115, and the second upper frame point II is connected to the first ground point 115.

[0161] If the first antenna 110 is in the positioning end state, then both the first upper frame point I and the second upper frame point II are connected to the first grounding point 115.

[0162] In this embodiment of the disclosure, if the first antenna is in the positioning working state, the first feed source needs to act on the first antenna, thereby adjusting the switching state of the first switch module so that the first upper frame point is disconnected from the first ground point.

[0163] Here, since the second feed is not required and the first antenna does not need to work (e.g., the Wi-Fi antenna does not need to operate), the switching state of the first switch module can be adjusted to connect the second upper frame point with the first ground point, thus reducing the interference of the first antenna to the second antenna.

[0164] In this embodiment of the present disclosure, when the first antenna is in the positioning completion state, in order to reduce the interference of the first antenna to the second antenna, both the first upper frame point and the second upper frame point can be connected to the first grounding point, thereby short-circuiting the first antenna and the second antenna to ground, and neither the first feed nor the second feed will act on the first antenna. In this way, the first antenna and the second antenna can be electromagnetically coupled, which not only enhances the radiation characteristics of the second antenna, but also reduces the interference of the first antenna to the second antenna.

[0165] It is understandable that when the first antenna is in different states, adjusting the first switching module of the first antenna can enable the first antenna to both work and be electromagnetically coupled with the second antenna. This not only enhances the radiation characteristics of the second antenna but also reduces the interference of the first antenna to the second antenna, thereby improving the transmission and reception performance of the second antenna.

[0166] In some embodiments, the signal circuit of the first antenna further includes:

[0167] The tuning circuit, connected between the first feed and the first upper frame point, is configured to adjust the resonant frequency of the first antenna when the second antenna transmits and receives wireless signals, so that the resonant frequency of the first antenna is outside the operating frequency band of the second antenna.

[0168] In this embodiment, when the second antenna is in the active state and the first antenna is in the positioning completed state, the resonant frequency of the first antenna can be adjusted by a tuning circuit so that the resonant frequency of the first antenna is outside the operating frequency band of the second antenna. Alternatively, when the second antenna is in the active state and the first antenna is in the positioning state, the resonant frequency of the first antenna can also be adjusted by a tuning circuit so that the resonant frequency of the first antenna is outside the operating frequency band of the second antenna. This achieves positioning while reducing interference from the first antenna to the second antenna during positioning.

[0169] For example, the second antenna is a satellite antenna that can cover the 1.5GHz to 2.5GHz frequency band. By using a tuning circuit, the resonant frequency of the first antenna can be pushed down to beyond 1GHz. In this way, by making the resonant frequency of the first antenna far away from the coverage band of the satellite antenna, the interference of the first antenna to the second antenna can be reduced, allowing the satellite antenna to perform better mobile communication.

[0170] It is understandable that by setting up a tuning circuit to adjust the resonant frequency of the first antenna, the interference of the first antenna to the second antenna can be reduced even when the first antenna is working.

[0171] In some embodiments, such as Figure 4 As shown, the second line is formed by the third upper frame point III, the fourth upper frame point IV, the fifth upper frame point V, and the sixth upper frame point VI;

[0172] The signal circuit of the second antenna includes:

[0173] The second switch module S2 is connected to the third upper frame point III, the fourth upper frame point IV, and the second ground point 118;

[0174] The third feed 119 is connected to the sixth upper frame point VI, and a third node is formed on the connection line between the sixth upper frame point VI and the third feed 119.

[0175] The third switch module S3 is connected to the fifth upper frame point V, the third node, and the second grounding point 118;

[0176] When the second antenna 111 is in a stopped working state, if the first antenna 110 or the third antenna 112 transmits or receives wireless signals, the switching state of the second switch module S2 and the switching state of the third switch module S3 are adjusted.

[0177] In this embodiment of the disclosure, such as Figure 7 As shown, the horizontal axis represents frequency f, and the vertical axis represents return loss S11. The third antenna includes a satellite antenna operating at 1.5GHz to 2.5GHz, and the corresponding third feed source can be the feed source of the satellite antenna. For example, when the third switch module disconnects the connection between the third node and the first grounding point, the second antenna transmits and receives wireless signals under the action of the third feed source.

[0178] The aforementioned second line formation includes a third, fourth, fifth, and sixth upper frame point. In some embodiments, such as... Figure 4 As shown, a first gap is formed between the first antenna 110 and the second antenna 111; a second gap is formed between the second antenna 111 and the third antenna 112; the third upper frame point III and the fourth upper frame point IV are located near the first gap; the fifth upper frame point V and the sixth upper frame point VI are located near the second gap.

[0179] It is understandable that by setting multiple different top frame points on the second antenna and the second and third switch modules, the second antenna can be better electromagnetically coupled to other antennas (the first or third antenna) by adjusting the switching states of the second and third switch modules.

[0180] In this embodiment of the disclosure, such as Figure 4 As shown, the signal circuit of the second antenna 111 also includes a first impedance component 120 and a second impedance component 121. The first impedance component 120 is connected to the connection line between the third node and the third feed 119; the second impedance component 121 is connected between the connection line between the third node and the sixth upper frame point VI and the ground.

[0181] It should be noted that both the first impedance component and the second impedance component can be formed by cascading resistor components, capacitor components and / or inductor components.

[0182] For example, the first impedance component may include a third capacitor, and the second impedance component may include a first inductor; the third capacitor is connected to the connection line between the third node and the third feed source; one end of the first inductor is connected to the connection line between the third node and the sixth upper frame point, and the other end is grounded.

[0183] In this embodiment of the disclosure, different switching states of the second switch module correspond to different grounding states of the third and fourth upper frame points. For example, adjusting the switching state of the second switch module can connect the third upper frame point to the second grounding point; and / or connect the fourth upper frame point to the second grounding point.

[0184] In this embodiment of the disclosure, different switching states of the third switch module correspond to different grounding states of the third node and the fifth upper frame point. For example, adjusting the switching state of the third switch module can connect the third node and the second grounding point, thereby connecting the sixth upper frame point to the second grounding point; or, for another example, adjusting the switching state of the third switch module can connect the fifth upper frame point and the second grounding point.

[0185] It is understandable that when the second antenna is in a non-operational state, if the first antenna is transmitting and receiving wireless signals, adjusting the switching states of the second and third switching modules can enable electromagnetic coupling between the second and first antennas. This not only enhances the radiation characteristics of the first antenna but also reduces the interference of the second antenna on the first antenna, thereby improving the transmission and reception performance of the first antenna.

[0186] If the third antenna is transmitting and receiving wireless signals, adjusting the switching states of the second and third switching modules can enable electromagnetic coupling between the second and third antennas. This not only enhances the radiation characteristics of the third antenna but also reduces the interference of the second antenna on the third antenna, thereby improving the transmission and reception performance of the third antenna.

[0187] In some embodiments, such as Figure 4 As shown,

[0188] When the third antenna 112 is operating in the first frequency band, the sixth upper frame point VI is connected to the second ground point 118, and the third upper frame point III, the fourth upper frame point IV and the fifth upper frame point V are all disconnected from the second ground point 118.

[0189] When the third antenna 112 is operating in the second frequency band, the third upper frame point III, the fourth upper frame point IV, the fifth upper frame point V, and the sixth upper frame point VI are all connected to the second ground point 118.

[0190] The first frequency band is different from the second frequency band.

[0191] In this embodiment of the disclosure, the first frequency band includes the B3 frequency band for mobile cellular communication. That is, when the third antenna operates in the B3 frequency band for mobile cellular communication, by connecting the sixth upper frame point to the second ground point, and disconnecting the third, fourth, and fifth upper frame points from the second ground point, electromagnetic coupling between the second and third antennas can be achieved.

[0192] like Figure 8 As shown, the horizontal axis represents frequency f, and the vertical axis represents return loss S11. When the second antenna is in a non-operating state and the third antenna is operating in the first frequency band, adjusting the second and third switching modules can enable electromagnetic coupling between the second and third antennas. This electromagnetic coupling can then increase the radiation characteristics of the third antenna operating in the first frequency band.

[0193] like Figure 9 As shown, the horizontal axis represents frequency f, and the vertical axis represents efficiency. When the second antenna is in a non-operating state and the third antenna is operating in the first frequency band, the electromagnetic coupling formed by the second and third antennas will improve the transmission and reception efficiency by 0.5dB to 1dB.

[0194] Understandably, by adjusting the switching states of the second and third switch modules, the sixth upper frame point can be connected to the second grounding point, and the third, fourth, and fifth upper frame points can all be connected to the second grounding point. In this way, the second antenna can electromagnetically couple with the third antenna operating in the first frequency band, which not only enhances the radiation characteristics of the third antenna operating in the first frequency band but also reduces the interference of the second antenna on the third antenna.

[0195] In this embodiment of the disclosure, the second frequency band includes the B41 band and / or N78 band for mobile cellular communication.

[0196] Understandably, by adjusting the switching states of the second and third switch modules, the third, fourth, fifth, and sixth upper frame points are all connected to the second grounding point. In this way, the second antenna can electromagnetically couple with the third antenna operating in the second frequency band. Specifically, magnetic coupling can be performed first, followed by electrical coupling, which not only enhances the radiation characteristics of the third antenna operating in the second frequency band but also reduces interference from the second antenna to the third antenna.

[0197] It should be noted that the third antenna can also operate in frequency bands other than the first and second frequency bands. When the third antenna is operating in other frequency bands, the coupling between the third antenna and the second antenna can be achieved by adjusting the switching states of the second and third switching modules. Here, other frequency bands include, but are not limited to, the B40, N79, and / or B1 bands of mobile cellular communication.

[0198] In some embodiments, such as Figure 4 As shown, when the first antenna 110 is in the positioning working state, the fourth upper frame point IV, the fifth upper frame point V and the sixth upper frame point VI are all connected to the second ground point 118, and the third upper frame point III is disconnected from the second ground point 118.

[0199] When the first antenna 110 is in wireless fidelity working state, the third upper frame point III, the fourth upper frame point IV and the fifth upper frame point V are all connected to the second ground point 118, and the sixth upper frame point VI is disconnected from the second ground point 118.

[0200] It is understood that, regardless of whether the first antenna is in positioning mode or wireless fidelity mode, the embodiments of this disclosure can adjust the switching states of the second and third switching modules in the signal circuit of the second antenna to enable electromagnetic coupling between the second antenna and the first antenna. This not only enhances the radiation characteristics of the first antenna but also reduces the interference of the second antenna on the first antenna.

[0201] In some embodiments, such as Figure 4 As shown, the signal circuit of the third antenna 112 includes:

[0202] The fourth feed 122 is connected to the seventh upper frame point VII of the third antenna 112, and a fourth node is formed on the connection line between the seventh upper frame point VII and the fourth feed 122.

[0203] The fourth switch module S4 is connected to the fourth node and the third grounding point 123;

[0204] When the second antenna 111 is in operation, the switching state of the fourth switch module S4 is adjusted so that the second antenna 111 can be electromagnetically coupled to the third antenna 112.

[0205] In this embodiment of the disclosure, such as Figure 10 As shown, the horizontal axis represents frequency f, and the vertical axis represents return loss S11. The third antenna includes a mobile cellular antenna, and the fourth feed source can be the feed source for the mobile cellular antenna. For example, by adjusting the fourth switch module, the third antenna can transmit and receive wireless signals under the action of the fourth feed source.

[0206] It should be noted that the second antenna and the third antenna form a second gap, and the seventh upper frame point can be set close to the second gap.

[0207] It is understandable that when the second antenna is in operation, by setting up the fourth switch module, electromagnetic coupling between the second antenna and the third antenna can be achieved. This not only enhances the radiation characteristics of the second antenna but also reduces the interference of the third antenna on the second antenna, thereby improving the transmission and reception performance of the second antenna.

[0208] In some embodiments, such as Figure 4 As shown, when the second antenna 111 transmits and receives wireless signals, the switching state of the fourth switch module S4 is adjusted so that the seventh upper frame point VII is connected to the third grounding point 123.

[0209] In other words, by adjusting the switching state of the fourth switch module in the signal circuit of the third antenna, the seventh upper frame point of the third antenna is connected to the third ground point; by connecting the seventh upper frame point to the third ground point, the second antenna and the third antenna can be electromagnetically coupled.

[0210] In this embodiment of the disclosure, such as Figure 4 As shown, the signal circuit of the third antenna 112 also includes a fifth impedance component 124. The fifth impedance component 124 is connected to the connection line between the fourth node and the fourth feed 122.

[0211] It should be noted that the fifth impedance component may be formed by cascading resistor components, capacitor components, and / or inductor components. For example, the fifth impedance component may include a fourth capacitor.

[0212] For example, such as Figure 7 , Figure 11A , Figure 11B and Figure 11C As shown, when the second antenna is in operation, the first switch module of the first antenna and the fourth switch module of the third antenna can be adjusted so that the first antenna can operate in the GPSL1 band and not in the Wi-Fi band, and the third antenna can be deactivated and electromagnetically coupled to the second antenna to enhance the radiation performance of the second antenna.

[0213] This disclosure also provides an electronic device. The electronic device includes the antenna structure described in one or more of the above embodiments.

[0214] The aforementioned electronic devices include smartphones, tablets, laptops, or wearable devices. Wearable devices include, but are not limited to, smartwatches or smart bracelets.

[0215] It is understandable that electronic devices include antenna structures. These structures enable one antenna to transmit and receive wireless signals simultaneously with the other, enhancing the antenna's radiation characteristics and reducing interference between adjacent antennas due to overlapping operating frequency bands, thus improving antenna performance. Furthermore, electromagnetic coupling between adjacent antennas allows energy to be concentrated and radiated in a specific direction, improving the antenna's directivity.

[0216] This disclosure also provides an antenna adjustment method, which is applied to the electronic device described above. For example... Figure 12 As shown, the method for adjusting the antenna of an electronic device includes the following steps:

[0217] S1001. Detect the operating status of multiple antennas in electronic equipment;

[0218] S1002. When it is detected that one of the two adjacent antennas is in working state, adjust the circuit state of the signal circuit connected to the other antenna so that the two adjacent antennas can be electromagnetically coupled.

[0219] It is understandable that electromagnetic coupling between two adjacent antennas allows one antenna to transmit and receive wireless signals simultaneously with the other. This not only enhances the antenna's radiation characteristics but also reduces mutual interference caused by overlapping operating frequency bands, thereby improving antenna performance. Furthermore, electromagnetic coupling between adjacent antennas concentrates energy radiation in a specific direction, improving the antenna's directivity.

[0220] In some embodiments, when a difference in the operating state of one of two adjacent antennas is detected, the circuit state of the signal circuit connected to the other antenna is adjusted so that the two adjacent antennas can perform electromagnetic coupling, including:

[0221] When the second antenna among multiple antennas is detected to be operational, the circuit state of the signal circuit of the first antenna among the multiple antennas is adjusted so that the second antenna and the first antenna can be electromagnetically coupled; and / or,

[0222] Adjust the circuit state of the signal circuit of the third antenna among multiple antennas so that the second antenna and the third antenna can be electromagnetically coupled.

[0223] It is understandable that when the second antenna is in operation, adjusting the circuit state of the signal circuit connected to the first antenna can enable electromagnetic coupling between the first and second antennas. This not only enhances the radiation characteristics of the second antenna but also reduces the interference of the first antenna to the second antenna, thereby improving the transmission and reception performance of the second antenna.

[0224] Furthermore, when the second antenna is in operation, adjusting the circuit state of the signal circuit connected to the third antenna enables electromagnetic coupling between the third and second antennas. This not only enhances the radiation characteristics of the second antenna but also reduces the interference of the third antenna on the second antenna, thereby improving the transmission and reception performance of the second antenna.

[0225] In some embodiments, adjusting the circuit state of the signal circuit of the first antenna among a plurality of antennas so that the second antenna and the first antenna can be electromagnetically coupled includes:

[0226] Adjust the switching state of the first switch module in the signal circuit of the first antenna so that the second antenna and the first antenna can be electromagnetically coupled.

[0227] It is understandable that when the second antenna is in operation, adjusting the switching state of the first switching module enables electromagnetic coupling between the second antenna and the first antenna. This not only enhances the radiation characteristics of the second antenna but also reduces the interference of the first antenna on the second antenna, thereby improving the transmission and reception performance of the second antenna.

[0228] In some embodiments, adjusting the switching state of the first switching module in the signal circuit of the first antenna includes:

[0229] If the first antenna is in the positioning working state, adjust the switching state of the first switch module so that the first upper frame point of the first antenna is disconnected from the first ground point, and the second upper frame point of the first antenna is connected to the first ground point.

[0230] If the first antenna is in the positioning end state, adjust the switching state of the first switch module so that both the first upper frame point and the second upper frame point are connected to the first grounding point.

[0231] It is understandable that when the first antenna is in different states, adjusting the first switching module of the first antenna can enable the first antenna to both work and be electromagnetically coupled with the second antenna. This not only enhances the radiation characteristics of the second antenna but also reduces the interference of the first antenna to the second antenna, thereby improving the transmission and reception performance of the second antenna.

[0232] In some embodiments, adjusting the circuit state of the signal circuit of the third antenna among a plurality of antennas so that the second antenna and the third antenna can be electromagnetically coupled includes:

[0233] Adjust the switching state of the fourth switch module in the signal circuit of the third antenna so that the seventh upper frame point of the third antenna is connected to the third ground point;

[0234] By connecting the seventh upper frame point to the third grounding point, the second antenna and the third antenna can be electromagnetically coupled.

[0235] It is understandable that by setting up a fourth switch module, electromagnetic coupling between the second antenna and the third antenna can be achieved, which can not only enhance the radiation characteristics of the second antenna, but also reduce the interference of the third antenna on the second antenna, thereby improving the transmission and reception performance of the second antenna.

[0236] In some embodiments, the method further includes:

[0237] When the second antenna is in a non-operating state, if the first or third antenna is transmitting or receiving wireless signals, the switching state of the second switch module and the switching state of the third switch module in the signal circuit of the second antenna are adjusted.

[0238] It is understandable that when the second antenna is in a non-operational state, if the first antenna is transmitting and receiving wireless signals, adjusting the switching states of the second and third switching modules can enable electromagnetic coupling between the second and first antennas. This not only enhances the radiation characteristics of the first antenna but also reduces the interference of the second antenna on the first antenna, thereby improving the transmission and reception performance of the first antenna.

[0239] If the third antenna is transmitting and receiving wireless signals, adjusting the switching states of the second and third switching modules can enable electromagnetic coupling between the second and third antennas. This not only enhances the radiation characteristics of the third antenna but also reduces the interference of the second antenna on the third antenna, thereby improving the transmission and reception performance of the third antenna.

[0240] In some embodiments, if the first antenna or the third antenna transmits or receives wireless signals, adjusting the switching state of the second switching module and the switching state of the third switching module in the signal circuit of the second antenna includes:

[0241] When the third antenna is operating in the first frequency band, the switching states of the second and third switching modules are adjusted so that the sixth upper frame point of the third antenna is connected to the second ground point, and the third, fourth, and fifth upper frame points of the third antenna are disconnected from the second ground point.

[0242] When the third antenna is operating in the second frequency band, adjust the switching state of the second switch module and the switching state of the third switch module so that the third upper frame point, the fourth upper frame point, the fifth upper frame point and the sixth upper frame point are all connected to the second grounding point.

[0243] The first frequency band is different from the second frequency band.

[0244] It is understandable that by adjusting the switching states of the second and third switching modules, electromagnetic coupling can be achieved between the second antenna and the third antenna operating in the first frequency band, as well as between the second antenna and the third antenna operating in the second frequency band. This not only enhances the radiation characteristics of the third antenna operating in both the first and second frequency bands but also reduces interference from the second antenna to the third antenna.

[0245] In some embodiments, if the first antenna or the third antenna transmits or receives wireless signals, adjusting the switching state of the second switching module and the switching state of the third switching module in the signal circuit of the second antenna includes:

[0246] When the first antenna is in the positioning working state, adjust the switching state of the second switch module and the switching state of the third switch module so that the fourth, fifth and sixth upper frame points of the second antenna are all connected to the second grounding point, and the third upper frame point of the second antenna is disconnected from the second grounding point.

[0247] When the first antenna is in wireless fidelity working state, adjust the switching state of the second switch module and the switching state of the third switch module so that the third, fourth and fifth upper frame points are all connected to the second grounding point, and the sixth upper frame point is disconnected from the second grounding point.

[0248] It is understood that, regardless of whether the first antenna is in positioning mode or wireless fidelity mode, the embodiments of this disclosure can adjust the switching states of the second and third switching modules in the signal circuit of the second antenna to enable electromagnetic coupling between the second antenna and the first antenna. This not only enhances the radiation characteristics of the first antenna but also reduces the interference of the second antenna on the first antenna.

[0249] This disclosure also proposes an electronic device. Figure 13 This is a schematic diagram illustrating the structure of an electronic device according to an exemplary embodiment. For example... Figure 13 As shown, the electronic device 2000 mainly includes:

[0253] The first adjustment submodule is configured to, when detecting that the second antenna among the plurality of antennas is in the operating state, adjust the circuit state of the signal circuit of the first antenna among the plurality of antennas, so that the second antenna and the first antenna can be electromagnetically coupled; and / or,

[0254] The second adjustment submodule is configured to adjust the circuit state of the signal circuit of the third antenna among the plurality of antennas, so that the second antenna and the third antenna can be electromagnetically coupled.

[0255] In some embodiments, the first adjustment submodule is further configured to adjust the switching state of the first switching module in the signal circuit of the first antenna, so that the second antenna and the first antenna can be electromagnetically coupled.

[0256] In some embodiments, the first adjustment submodule is further configured to adjust the switching state of the first switch module if the first antenna is in the positioning working state, such that the first upper frame point of the first antenna is disconnected from the first ground point, and the second upper frame point of the first antenna is connected to the first ground point.

[0257] If the first antenna is in the positioning end state, then adjust the switching state of the first switch module so that both the first upper frame point and the second upper frame point are connected to the first grounding point.

[0258] In some embodiments, the second adjustment submodule is further configured to adjust the switching state of the fourth switch module in the signal circuit of the third antenna, so that the seventh upper frame point of the third antenna is connected to the third ground point; through the connection between the seventh upper frame point and the third ground point, the second antenna and the third antenna can be electromagnetically coupled.

[0259] In some embodiments, the electronic device further includes:

[0260] The third adjustment submodule is configured to, when the second antenna is in the stopped working state, adjust the switching state of the second switch module and the switching state of the third switch module in the signal circuit of the second antenna if the first antenna or the third antenna is transmitting or receiving wireless signals.

[0261] In some embodiments, the third adjustment submodule is configured to adjust the switching state of the second switch module and the switching state of the third switch module when the third antenna is operating in the first frequency band, so that the sixth upper frame point of the third antenna is connected to the second ground point, and the third upper frame point, the fourth upper frame point and the fifth upper frame point of the third antenna are disconnected from the second ground point.

[0262] When the third antenna is operating in the second frequency band, the switching states of the second switch module and the third switch module are adjusted so that the third upper frame point, the fourth upper frame point, the fifth upper frame point and the sixth upper frame point are all connected to the second grounding point;

[0263] The first frequency band is different from the second frequency band.

[0264] In some embodiments, the third adjustment submodule is configured to adjust the switching state of the second switch module and the switching state of the third switch module when the first antenna is in the positioning working state, so that the fourth upper frame point, the fifth upper frame point and the sixth upper frame point of the second antenna are all connected to the second grounding point, and the third upper frame point of the second antenna is disconnected from the second grounding point.

[0265] When the first antenna is in wireless fidelity working state, adjust the switching state of the second switch module and the switching state of the third switch module so that the third upper frame point, the fourth upper frame point and the fifth upper frame point are all connected to the second grounding point, and the sixth upper frame point is disconnected from the second grounding point.

[0266] Regarding the apparatus in the above embodiments, the specific manner in which each module performs its operation has been described in detail in the embodiments related to the method, and will not be elaborated upon here.
