[0038] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, like reference numerals refer to like elements, unless indicated otherwise. The following description of exemplary embodiments is not representative of all possible embodiments consistent with the present disclosure. Rather, it is merely an example of apparatus and methods consistent with some aspects of the present disclosure as detailed in the appended claims.
[0039] The present disclosure provides an antenna module, which comprises:
[0040] a plurality of radiating branches arranged in the same region of the electronic device;
[0041] Each of the plurality of radiating branches operates in one of a global positioning system (GPS) frequency band, a wireless fidelity (Wi-Fi) 2.4G frequency band, or a Wi-Fi 5G frequency band.
[0042] Here, the antenna module provided by the present disclosure is arranged in an electronic device, which includes a mobile phone, a tablet computer, a smart watch, etc. The antenna module can be arranged in the same region of the electronic device, and perform wireless signal transmission and reception based on a plurality of radiating branches in the same region, thereby realizing wireless communication, positioning, charging, etc.
[0043] Referring to Figure 1 , Figure 1 is a structural schematic diagram of an antenna module according to an exemplary embodiment Figure 1 ; Figure 1 The antenna module shown in the figure includes three radiating branches arranged side by side, and the gap between the two adjacent radiating branches is provided.
[0044] The electronic device in which the antenna module provided by the present disclosure is active in an actual wireless communication scenario. Exemplarily, the wireless communication scenario can be a multi-device scenario, for example, in a scenario of configuring a network for an electronic device, the multi-device interaction such as a router and different electronic devices is used to complete the network configuration for the electronic device.
[0045] Referring to Figure 2 , Figure 2 is a schematic diagram of a wireless communication scenario applied by an electronic device according to an exemplary embodiment. The wireless communication network environment includes an electronic device 201A and 201B, a Wi-Fi access point 202, a cellular base station 203, and a network 204. Here, when the electronic device 201A and the electronic device 201B transmit and receive wireless signals using a wireless local area network or a cellular network, the electronic device 201A and the electronic device 201B can switch between the Wi-Fi and the cellular network through the information transmission between the Wi-Fi access point 202 and the cellular base station 203 and the network 204. According to the present disclosure, as Figure 2In the illustrated network environment, the WiFi connection is stopped when receiving an instruction to stop the cellular circuit from performing wireless transmission; and the WiFi connection is resumed when receiving an instruction to stop the cellular circuit from performing wireless transmission.
[0046] In the embodiments of the present disclosure, the multiple radiation branches in the same region of the electronic device can be understood as being distributed on the frame, or being distributed on one side of the frame and being formed as a frame antenna; of course, the multiple radiation branches in the same region can also be understood as being distributed on the back cover and being formed as a patch antenna, and the embodiments of the present disclosure do not make superfluous repetition and limitation on this.
[0047] Here, the multiple radiation branches can be arranged in a spaced manner or share the same ground terminal; among them, two adjacent radiation branches can be arranged in a head-to-head manner, or in a parallel and symmetrical manner, or in a surrounding manner, and the embodiments of the present disclosure do not make limitation on this.
[0048] In the embodiments of the present disclosure, each radiation branch of the multiple radiation branches has one feeding terminal, and each feeding terminal is connected to one radio frequency terminal and transmits and receives one of the GPS frequency band, the wireless fidelity (WiFi) 2.4G frequency band or the WiFi 5G frequency band through the connected radio frequency terminal.
[0049] When the radio frequency terminal connected to the feeding terminal of the radiation branch is a GPS radio frequency terminal, the radiation branch can transmit and receive GPS wireless signals, so that the electronic device where the antenna module is located can realize wireless positioning in scenarios such as aviation, navigation, vehicle navigation, outdoor exploration, etc. Here, the GPS frequency band includes L1 frequency band, L2 frequency band or L5 frequency band, wherein the range of the L1 frequency band is 1575.42 MHz±1.023 MHz, the range of the L2 frequency band is 1227.60 MHz±1.023 MHz, and the range of the L5 frequency band is 1176.45 MHz±1.023 MHz.
[0050] When the radio frequency terminal connected to the feeding terminal of the radiation branch is a WiFi radio frequency terminal, the radiation branch can transmit and receive wireless signals of the WiFi 2.4G frequency band or the WiFi 5G frequency band, so that the electronic device where the antenna module is located can realize data transmission at different rates within a limited range. Here, the WiFi 2.4G frequency band represents a specified WiFi frequency band with a center frequency of 2.4 GHz, and the WiFi 5G frequency band represents a specified WiFi frequency band with a center frequency of 5 GHz.
[0051] It should be noted that each radiation branch can be selected to work in one of the above GPS frequency band, WiFi 2.4G frequency band or WiFi 5G frequency band.
[0052] In some examples, Figure 1Among the three radiation branches shown, the middle radiation branch can transmit and receive GPS signals, and the two end radiation branches can transmit and receive wifi signals; wherein, the two end radiation branches can each transmit and receive 2.4G frequency band wireless signals, or each transmit and receive wifi 5G frequency band wireless signals, or one transmit and receive wifi 2.4G frequency band wireless signals and the other transmit and receive wifi 5G frequency band wireless signals.
[0053] In other examples, the multiple radiation branches in the same area can each transmit and receive the same type of wireless signals in the same frequency band, for example, each transmit and receive L2 frequency band signals in the GPS frequency band, or each transmit and receive wifi 2.4G signals.
[0054] In yet other examples, the multiple radiation branches in the same area can each transmit and receive the same type of wireless signals but in different frequency bands, for example, each transmit and receive signals in the GPS frequency band, but each radiation branch transmits and receives L1 frequency band signals, L2 frequency band signals, and L5 frequency band signals; or each transmit and receive wifi signals, but each radiation branch transmits and receives wifi 2.4G frequency band signals and wifi 5G frequency band signals.
[0055] In some of the above examples, the feed end of each radiation branch can be connected to different radio frequency ends through a conductive spring and a matching circuit; the number, type, and connection relationship of the components of the matching circuits of different radiation branches can be the same or different, so that the frequency bands of the wireless signals transmitted and received by each of the multiple radiation branches can be the same or different, for example, each radiation branch is connected to a wifi radio frequency end, but transmits and receives wifi 2.4G frequency band signals and wifi 5G frequency band signals respectively. Among them, the conductive spring described above can be a metal spring, or a spring formed of a semiconductor material or a composite material.
[0056] In the embodiments of the present disclosure, the antenna module includes multiple radiation branches arranged in the same area of the electronic device, and each radiation branch operates in one of the GPS frequency band, the wifi 2.4G frequency band, or the wifi 5G frequency band. In this way, each radiation branch arranged in the same area can individually transmit and receive wireless signals in a specified frequency band of the above frequency bands. Compared with integrating a routing device to cover multiple frequency bands and multiple types of wireless signals, not only is the device loss caused by arranging the routing device saved, but also the antenna performance of each radiation branch transmitting and receiving the corresponding frequency band is improved. Moreover, through the design of the above radiation branches, the flexibility of the layout of the radiation branches in the antenna module is also embodied.
[0057] In some embodiments, as shown in Figure 1 The multiple radiation branches include at least one first radiation branch 1.
[0058] The working frequency band of the first radiating branch 1 is L1 frequency band in GPS frequency band.
[0059] Here, Figure 1 A first radiating branch 1 is shown; in an actual antenna module, a plurality of first radiating branches can also be arranged; it should be noted that when a plurality of first radiating branches are arranged, the plurality of first radiating branches can be used for transmitting and receiving wireless signals of L1 frequency band, or part of the first radiating branches can be used only for transmitting wireless signals of L1 frequency band, and part of the first radiating branches can be used only for receiving wireless signals of L1 frequency band.
[0060] In the embodiments of the present disclosure, in combination with Figure 1 The first radiating branch 1 is provided with a first feeding end 11, and the first feeding end 11 is connected with a GPS radio frequency end.
[0061] In this way, the embodiments of the present disclosure can make the electronic device capable of using GPS signals for wireless positioning, thereby enriching the functions of the electronic device.
[0062] In some embodiments, as shown in Figure 1 The plurality of radiating branches further include a second radiating branch 2 and a third radiating branch 3.
[0063] The working frequency bands of the second radiating branch 2 and the third radiating branch 3 are wifi 2.4G frequency band, and the second radiating branch 2 and the third radiating branch 3 are arranged at two ends of the first radiating branch 1 respectively.
[0064] Here, the second radiating branch and the third radiating branch are arranged at opposite two ends of the first radiating branch, the second radiating branch can be arranged spaced apart from one end of the first radiating branch, so as to release wireless signals by means of the spacing, or the second radiating branch can be arranged in common with one end of the first radiating branch, so as to form respective current loops by means of the common back-to-ground branch, thereby reducing signal interference between adjacent radiating branches; of course, the third radiating branch can also be arranged spaced apart from or in common with the other end of the first radiating branch, which will not be described herein again.
[0065] It should be noted that since the length of the radiating branch is inversely proportional to the frequency of the wireless signal transmitted and received thereby, the present disclosure sets the length of the second radiating branch and the length of the third radiating branch to be the same or similar, and sets the length of the second radiating branch and the length of the third radiating branch to be smaller than the length of the first radiating branch, so that the frequency of the wireless signal transmitted and received by the second radiating branch and the third radiating branch is greater than the frequency of the wireless signal transmitted and received by the first radiating branch. That is, the second radiating branch and the third radiating branch work in a frequency band with a center frequency of 2.4 GHz, and the first radiating branch works in L1 frequency band with a center frequency of 1.575 GHz.
[0066] In the embodiments of the present disclosure, each of the second radiation branch and the third radiation branch has a radio frequency end; in combination Figure 1 As shown in the figure, the second radiation branch 2 is provided with a second feeding end 21, and the third radiation branch 3 is provided with a third feeding end 31.
[0067] The third feeding end and the second feeding end can be connected to the same radio frequency end (wifi radio frequency end), or can be respectively connected to different radio frequency ends of the same type in the electronic device. When the third feeding end and the second feeding end are connected to the same radio frequency end, the second radiation branch and the third radiation branch can simultaneously transmit and receive wireless signals; or, a switch module can be arranged at the radio frequency end in the embodiments of the present disclosure, and the switch module switches the electrical connection between the second feeding end and the third feeding end through different switch states, so as to switch the second type of radiation branch and the third type of radiation branch to respectively transmit and receive wireless signals at different times.
[0068] It should be noted that, considering that the head and hand will affect the transmission of wireless signals when the electronic device is held, therefore, the second radiation branch and the third radiation branch are arranged at the two ends of the first radiation branch, and such an antenna layout can use another radiation branch to ensure the performance of the antenna in transmitting and receiving wireless signals of the same frequency band when the performance of one radiation branch in transmitting and receiving wireless signals is poor.
[0069] In some examples, the first radiation branch can be arranged at a flat frame of the electronic device, and at this time, the second radiation branch and the third radiation branch are arranged on the same side (or partially arranged on the same side, or partially arranged at the connecting corner of the side and other sides) of the electronic device as the first radiation branch; wherein the second radiation branch and the third radiation branch are located at opposite ends of the first radiation branch, for example Figure 1 As shown in the figure.
[0070] In other examples, the first radiation branch can be arranged at a folding frame of the electronic device, that is, at the connecting corner of two sides, and at this time, the second radiation branch and the third radiation branch are arranged on the two sides respectively.
[0071] In the embodiments of the present disclosure, by arranging the second radiation branch and the third radiation branch, the electronic device can transmit and receive wifi signals to realize short-distance and fast transmission; and by arranging the second radiation branch and the third radiation branch to transmit and receive wireless signals of the same type and same frequency band, the performance of the antenna module in transmitting and receiving wifi 2.4G signals can be improved.
[0072] In some embodiments, the plurality of radiation branches further comprise: a fourth radiation branch;
[0073] The fourth radiating branch operates in the 5G Wi-Fi band and is located between the first and second radiating branches.
[0074] See here. Figure 3 , Figure 3 This is a schematic diagram of the distribution of multiple radiating branches according to an exemplary embodiment; wherein, the fourth radiating branch 4 is disposed between the first radiating branch 1 and the second radiating branch 2, and has a fourth feed terminal 41, which is connected to a wifi radio frequency terminal for transmitting and receiving wifi wireless signals, and operates in a designated frequency band with a center frequency of 5GHz.
[0075] The fourth, second, and third power supply terminals can be connected to the same radio frequency terminal (Wi-Fi radio frequency terminal), or they can be connected to different locations in the electronic device but to the same type of radio frequency terminal.
[0076] Compared to 5GHz Wi-Fi signals, 2.4GHz Wi-Fi signals have advantages such as lower signal frequency, less attenuation during propagation, wider coverage, and stronger penetration, making them widely applicable in home and indoor environments. Conversely, compared to 5GHz Wi-Fi signals, 5GHz Wi-Fi signals offer higher data transmission rates and stronger anti-interference capabilities, making them suitable for other environments requiring high-speed data transmission, such as big data centers. Therefore, this embodiment utilizes the second (and third) and fourth radiating stubs to transmit and receive these two different frequency band Wi-Fi signals, effectively expanding the application scenarios of the antenna module.
[0077] In this embodiment of the disclosure, the length of the fourth radiating branch is further set to be less than the length of the second radiating branch (and the third radiating branch), so that the frequency of the wireless signal transmitted and received by the fourth radiating branch is lower than the frequency of the wireless signal transmitted and received by the second radiating branch (and the third radiating branch).
[0078] In this embodiment, one end of the fourth radiating stub is close to the first radiating stub, and the other end of the fourth radiating stub is close to the second radiating stub. One end of the fourth radiating stub may be in contact with the first radiating stub or be spaced apart from it. Given the types and frequency bands of the wireless signals transmitted and received by the fourth and first radiating stubs, the crosstalk between them is relatively small, and therefore can be freely configured. Since the fourth and second radiating stubs transmit and receive the same type of wireless signal, the higher harmonics of the wireless signal transmitted and received by the longer second radiating stub may fall within the frequency band of the signal transmitted and received by the fourth radiating stub, thus adversely affecting the fourth radiating stub. Therefore, in this embodiment, the other end of the fourth radiating stub is spaced apart from the second radiating stub to minimize signal interference.
[0079] In some embodiments, see Figure 4 , Figure 4 This is a schematic diagram of the structure of an antenna module according to an exemplary embodiment. Figure 2 The antenna module also includes the first rib 6.
[0080] The first rib 6 is located between the fourth radial branch 4 and the second radial branch 2, and has gaps between itself and both the fourth radial branch 4 and the second radial branch 2.
[0081] Here, since the higher harmonics of the wireless signals transmitted and received by the longer second radiating stub may fall into the band of the signals transmitted and received by the fourth radiating stub, thus adversely affecting the fourth radiating stub; therefore, in this embodiment of the present disclosure, the fourth radiating stub and the second radiating stub are provided with a gap, and within the gap, a first rib is provided that is not connected to the fourth radiating stub and the second radiating stub, so as to use the first rib to destroy the electromagnetic effect between the two radiating stubs and reduce the crosstalk of higher harmonics.
[0082] The first rib can be a metal rib, such as a copper rib; the first rib can also be made of a conductive polymer such as polyaniline, and this disclosure does not limit this.
[0083] In this embodiment, the shape of the first rib is not limited; it can be bent or straight. The first rib is connected to the ground plane in the electronic device, and in addition to blocking signal interference, it can also ground the second and fourth radiating branches.
[0084] In this embodiment of the present disclosure, by setting a first rib, the signal interference between adjacent second and fourth radiating stubs can be reduced, the isolation between the second and fourth radiating stubs can be improved, and thus the antenna performance of the radiating stubs can be improved.
[0085] In some embodiments, such as Figure 4 As shown, the multiple radiating branches also include: the fifth radiating branch 5;
[0086] The fifth radiating branch 5 operates in the 5G Wi-Fi band, and is located on the side of the third radiating branch 3 away from the first radiating branch 1.
[0087] Here, the fifth radiating branch is also equipped with a fifth feed terminal, which is connected to the Wi-Fi radio frequency terminal for transmitting and receiving Wi-Fi wireless signals and operates in a designated frequency band with a center frequency of 5GHz. The fourth and fifth feed terminals can be connected to the same radio frequency terminal (Wi-Fi radio frequency terminal), or they can be connected to different locations in the electronic device but to radio frequency terminals of the same type.
[0088] In this embodiment of the disclosure, the length of the fifth radiating branch is less than the length of the second radiating branch (and the third radiating branch) so that the frequency of the wireless signal transmitted and received by the fifth radiating branch is lower than the frequency of the wireless signal transmitted and received by the second radiating branch (and the third radiating branch); and the length of the fifth radiating branch is the same as or similar to the length of the fourth radiating branch so that the fifth radiating branch and the fourth radiating branch transmit and receive wireless signals of the same type and frequency band (Wi-Fi 5G band).
[0089] It should be noted that the high-order harmonic interference between the third and fifth radiating branches in this embodiment is similar to that between the second and fourth radiating branches. Therefore, in this embodiment, the fifth radiating branch is located on the side of the third radiating branch away from the first radiating branch, and is spaced apart from the third radiating branch to minimize interference between signals.
[0090] In addition, considering that the head and hands can affect the transmission and reception of wireless signals when the electronic device is held, the embodiments of this disclosure place the fifth and fourth radiating branches at both ends of the first radiating branch. Such an antenna layout can ensure the performance of the antenna in transmitting and receiving this type of wireless signal when the performance of one radiating branch in transmitting and receiving wireless signals is poor.
[0091] In this embodiment of the disclosure, by setting a fourth radiating stub and a fifth radiating stub to transmit and receive wireless signals of the same type and frequency band, the comprehensiveness and flexibility of the antenna module in transmitting and receiving Wi-Fi 5G signals can be improved.
[0092] In some embodiments, such as Figure 4 As shown, the antenna module also includes a second rib 7;
[0093] The second rib 7 is located between the fifth radial branch 5 and the third radial branch 3, and has gaps between it and both the fifth radial branch 5 and the third radial branch 3.
[0094] Here, since the higher harmonics of the wireless signals transmitted and received by the longer third radiating stub may fall into the band of the signals transmitted and received by the fifth radiating stub, thus adversely affecting the fifth radiating stub; therefore, in this embodiment of the present disclosure, a gap is provided between the fifth radiating stub and the third radiating stub, and a second rib is provided in the gap that is not connected to the third radiating stub and the fifth radiating stub, so as to use the second rib to destroy the electromagnetic effect between the two radiating stubs and reduce the crosstalk of higher harmonics.
[0095] It should be noted that the materials and shapes of the second rib and the first rib can be the same or different. The specific settings are the same as the design of the first rib, and will not be described in detail here.
[0096] In this embodiment of the disclosure, by setting a second rib, the signal interference between adjacent third and fifth radiating stubs can be reduced, the isolation between the third and fifth radiating stubs can be improved, and thus the antenna performance of the radiating stubs can be improved.
[0097] In some embodiments, the second radiating branch has two ends disposed opposite to each other, one end being close to the first radiating branch and the other end being away from the first radiating branch;
[0098] Both ends of the second radial branch are suspended.
[0099] like Figure 4 As shown, the two opposite ends of the second radiating branch 2 include a first end 22 and a second end 23, and a second power supply end 21 is disposed between the first end 22 and the second end 23; and the first end 22 is one end close to the first radiating branch 1, and the second end 22 is the other end far away from the first radiating branch 1.
[0100] In this embodiment, both the first end and the second end are suspended, meaning the second radiating branch is not directly connected to the ground plane of the electronic device. At least one end of the first and second ends can form an induced capacitance with the ground plane. When an electrical signal is fed into the second feed end of the second radiating branch, an electromagnetic field is generated. When another object (e.g., a person) approaches the electromagnetic field, it causes a change in the electromagnetic field, which is reflected in a change in the induced capacitance. Thus, the proximity sensor (SAR sensor) can determine whether another object is approaching the electronic device by observing the change in the induced capacitance.
[0101] In practice, the second radiating branch is placed on top of the electronic device where the antenna module is located (i.e., near the camera module) to help the electronic device better achieve non-contact object detection.
[0102] It should be noted that in the antenna module proposed in the embodiments of this disclosure, the side of the second end that is far from the first end may not have a radiating stub, or it may have other radiating stubs that transmit and receive different wireless signals from the second radiating stub. The embodiments of this disclosure do not impose any restrictions on this.
[0103] The embodiments disclosed herein enable the antenna module to achieve non-contact object detection by using a suspended second radiating branch, thereby improving the practicality of electronic devices.
[0104] In this embodiment of the disclosure, the length of at least one of the multiple radiating branches has a preset ratio with respect to the wavelength corresponding to the center frequency of the transmitted and received wireless signal.
[0105] It is understandable that the size of the radiating stub is comparable to or a portion of the wavelength of the electromagnetic wave (wireless signal). If the size of the radiating stub is set to a preset ratio with the wavelength of the wireless signal, the radiating stub can exhibit resonant characteristics at a specific frequency. In the resonant state, the radiating stub can more effectively transmit and receive wireless signals, thereby improving signal transmission efficiency. The specific frequency in the resonant state mentioned above is the center frequency of each radiating stub's wireless signal transmission and reception.
[0106] Thus, in this embodiment of the present disclosure, the length of each radiating stub can be set according to the relationship between the center frequency and wavelength of the wireless signals to be transmitted and received by each radiating stub and a preset ratio. The relationship between the center frequency (f) and wavelength (λ) of the wireless signal can be expressed as c = λ * f; where c is the speed of light, the speed at which the wireless signal propagates in a vacuum.
[0107] It should be noted that the preset ratios corresponding to each radiating stub can be the same or different; in this embodiment, each preset ratio is less than 1, which can not only achieve effective resonance of each radiating stub, but also reduce the length of each radiating stub and improve the flexibility of antenna module layout.
[0108] Here, the preset ratios can be one-half, one-quarter, or one-eighth, etc.
[0109] In some embodiments, at least one of the plurality of radiating branches operates in a quarter-wavelength mode.
[0110] Theory and practice have proven that the antenna's transmit and receive conversion efficiency is highest when the length of the radiating stub is one-quarter of the wavelength of the transmitted and received wireless signal. At this time, the radiating stub operates in quarter-wavelength mode. Thus, in the embodiments of this disclosure, the preset ratio corresponding to each radiating stub can be set to one-quarter, that is, each radiating stub adopts the intrinsic quarter-wavelength mode for transmitting and receiving wireless signals, which can make each radiating stub have better radiation performance.
[0111] In some embodiments, one or more of the aforementioned radiating branches may also cover other types of signal frequency bands, or radiate other types of frequency bands.
[0112] Each radiating stub can be connected to a tuning circuit, and the resonant frequency of the radiating stub can be adjusted through the tuning effect of the tuning circuit, so that the radiating stub can cover wireless signals of the same type but different operating frequency bands.
[0113] In some embodiments, at least one of the plurality of radiating branches also operates in a preset communication frequency band;
[0114] The preset communication frequency bands include cellular communication frequency bands or Bluetooth communication frequency bands.
[0115] In some embodiments, when structural space is limited in an electronic device, the feed end of at least one radiating stub can be connected to a different type of radio frequency terminal.
[0116] Here, since cellular communication bands such as B41, B38, or N77, as well as GPS and Wi-Fi 2.4G bands, are all located in low-frequency bands, the power supply terminals of the first, second, or third radiating stubs can be connected to the cellular communication radio frequency terminals so that the first, second, or third radiating stubs can also transmit and receive wireless signals in the cellular communication bands.
[0117] Furthermore, since the Bluetooth communication frequency band includes a designated frequency band centered at 2.4 GHz, the embodiments of this disclosure can utilize the power supply terminal of the second or third radiating stub to connect to the Bluetooth communication radio frequency terminal, so that the second or third radiating stub can also transmit and receive Bluetooth communication in the 2.4 GHz frequency band.
[0118] It should be noted that the aforementioned preset communication frequency band may also include the L1 and L5 frequency bands of the short message communication frequency band. In this case, the embodiments of this disclosure may also utilize the first radiating branch to cover the aforementioned short message communication frequency band.
[0119] The embodiments disclosed herein expand the coverage range of the antenna module for transmitting and receiving wireless signals and improve the overall effectiveness of the antenna module by setting at least one of the multiple radiating branches, which also operates in other frequency bands.
[0120] This disclosure also provides an electronic device including the antenna module proposed in the above embodiments.
[0121] Here, the antenna module includes multiple frames, and the aforementioned radiating stubs are respectively disposed on the multiple frames; or, the multiple frames are conductive frames, and at least a portion of the multiple conductive frames is reused as each radiating stub.

[0123] It should be noted that the aforementioned conductive frame can be part of the magnesium alloy MDA plastic mid-frame. The MDA mid-frame has high strength, corrosion resistance and good heat dissipation performance, and its manufacturing cost is also lower than that of conventional metal mid-frames.
[0124] This disclosure improves the structural utilization and layout flexibility of electronic devices by utilizing a frame-mounted antenna module.
[0125] In some embodiments, the radiating stubs of the antenna module that operate in the GPS band are located at a corner position between the top and side of the electronic device.
[0126] In conjunction with the antenna module proposed above in this disclosure, the radiating stub operating in the GPS frequency band is the aforementioned first radiating stub; the first radiating stub can be located at the top and side corners of the electronic device.
[0127] Example type, combined Figure 4 The second frame S2 is a bent frame, located at the corner between the top and left side (or the right side in actual setup) of the electronic device. The first radiating branch 1 is set on the second frame S2, or the corner portion of the second frame S3 is reused as the first radiating branch 1.
[0128] In some embodiments, the top and sides of the electronic device each include at least one radiating stub operating in the 2.4G Wi-Fi band;
[0129] The top and side of the electronic device each include at least one radiating branch operating in the 5G Wi-Fi band.
[0130] Here, one or more radiating branches operating in the 2.4G WiFi band are respectively set on the top and side (left or right side) of the electronic device, and one or more radiating branches operating in the 5G WiFi band are also respectively set.
[0131] For example, a second radiating branch operating in the 2.4G Wi-Fi band and a fourth radiating branch operating in the 5G Wi-Fi band are disposed at the top; a third radiating branch operating in the 2.4G Wi-Fi band and a fifth radiating branch operating in the 5G Wi-Fi band are disposed on the side.
[0132] Combination Figure 4 The first border S1 is a horizontal border (top border) located on one side of the second border S2, and the third border S3 is a vertical border (left or right border) located on the other side of the second border S2. In this example, the second radial branch 2 is set in the first border S1; or, the first border S1 is reused as the second radial branch 2; the second border S2 includes four border segments, wherein the first border segment is set as the fourth radial branch 4 or reused as the fourth radial branch 4, the second border segment is set as the first radial branch 1 or reused as the first radial branch 1, the third border segment is used as the grounding branch 8, wherein the grounding branch 8 is the common ground end of the first radial branch 1 and the third radial branch 3; the fourth border segment is set as the third radial branch 3 or reused as the third radial branch 3; the fifth radial branch 5 is set in the third border S3, or the third border S3 is reused as the fifth radial branch 5.
[0133] For example, the above-mentioned electronic device can be a mobile phone. In this case, the second and third radiating branches form a 2.4G Wi-Fi antenna for transmitting and receiving 2.4GHz Wi-Fi signals; the fourth and fifth radiating branches can form a 5G Wi-Fi antenna for transmitting and receiving 5GHz Wi-Fi signals; and the first radiating branch can form a GPS antenna for transmitting and receiving GPS signals in the L1 band (1575.42MHz±1.023MHz).
[0134] In this example, a first rib and a second rib are respectively provided between adjacent Wi-Fi 2.4G antennas and Wi-Fi 5G antennas to reduce the mutual coupling between Wi-Fi antennas; and, in this embodiment of the present disclosure, the GPS antenna, Wi-Fi 2.4G antenna and Wi-Fi 5G antenna are all used as separate antennas for transmitting and receiving wireless signals, which can save the combining device at the chip level, save device loss and cost loss, and improve the overall performance of the antenna module.
[0135] In this embodiment, the GPS antenna, 2.4G Wi-Fi antenna, and 5G Wi-Fi antenna all utilize intrinsic quarter-wavelength mode for signal transmission and reception, which enables each antenna to have optimal radiation performance.
[0136] In this embodiment of the disclosure, the GPS antenna and the two 2.4G Wi-Fi antennas can also be compatible with other antennas and can switch to transmit and receive wireless signals in other frequency bands (such as B41, B38 or N77 cellular communication bands) when needed.
[0137] In addition, the aforementioned second radiating branch (Wi-Fi 2.4G antenna) can be suspended, thereby helping electronic devices to achieve non-contact object proximity detection.
[0138] Thus, the embodiments of this disclosure utilize three frame segments to set five independent radiating branches for transmitting and receiving wireless signals, which improves the structural utilization of the electronic device and also improves the antenna performance of each radiating branch for transmitting and receiving wireless signals.
