It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0030] It is understood that in the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified. It should be noted that when an element is referred to as being "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intervening element present.

[0031] The electronic devices involved in the embodiments of this application can be handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE) (e.g., mobile phones), mobile stations (MS), etc. For ease of description, the devices mentioned above are collectively referred to as electronic devices.

[0032] In some embodiments, such as Figures 1-3 As shown, the electronic device 10 includes a display assembly 11, a mid-frame 12, and a cover assembly 13, as well as a radiator (not shown) and a radio frequency front-end module (not shown).

[0033] The display assembly 11 includes a display screen 111, which can be an OLED (Organic Light-Emitting Diode) screen or an LCD (Liquid Crystal Display) screen. The display screen 111 can be used to display information and provide an interactive interface for users. The shape of the display screen 111 can be rectangular or rounded rectangle. A rounded rectangle is sometimes also called a rounded rectangle, meaning that the four corners of the rectangle are rounded, and the four sides of the rectangle are roughly straight lines.

[0034] The middle frame 12 includes a middle plate and a frame surrounding the middle plate. The middle frame 12 provides support for electronic components or functional parts in the electronic device 10. The frame is generally rectangular and includes a top frame 121 and a bottom frame 123 facing away from each other, and a first side frame 122 and a second side frame 124 connecting the top frame 121 and the bottom frame 123. The first side frame 123 and the second side frame 124 are facing away from each other, and the top frame 121, the first side frame 122, the bottom frame 123, and the second side frame 124 are connected end-to-end and located on the outer periphery of the middle plate. The connections between the frames can be right-angle connections or rounded transition connections. Furthermore, the frame can be formed with radiators for radiating radio frequency signals of different frequency bands.

[0035] The cover plate assembly 13 is located on the side facing away from the display area of ​​the display screen 111 and is connected to the edge of the middle frame 12. Further, the display screen assembly 11 and the cover plate assembly 13 are located on opposite sides of the middle plate of the middle frame 12. An installation space can be formed between the cover plate assembly 13 and the display screen 111 for installing electronic components such as batteries, motherboards, and camera modules of the electronic device. The motherboard can integrate electronic components such as processors, storage units, power management modules, and baseband chips of the electronic device. The motherboard is located on the side facing away from the display area of ​​the display screen 111 and can be fixedly connected to the middle frame by screws or other structural components. The motherboard can be a PCB (Printed Circuit Board) or an FPC (Flexible Printed Circuit). In some embodiments, the motherboard can integrate a portion of the radio frequency circuitry for processing radio frequency signals, and can also integrate a controller for controlling the operation of the electronic device 10. The radio frequency circuitry includes a radiator and a radio frequency front-end module. Optionally, the radio frequency front-end module includes, but is not limited to, at least one amplifier, transceiver, coupler, low-noise amplifier (LNA), duplexer, etc. In addition, radio frequency circuits can also communicate with networks and other devices wirelessly.

[0036] The aforementioned wireless communications may use any communication standard or protocol, including but not limited to Global System for Mobile communication (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), email, Short Messaging Service (SMS), etc.

[0037] like Figure 4 As shown, the electronic device 10 provided in this application embodiment also includes a ground plane 200, a radiator 300, a feed source (not shown in the figure), and a radiating accessory 400.

[0038] In this embodiment, the ground plane 200 is used to carry the radiator 300 and provide a grounding signal to ground the radiator 300. The material of the ground plane 200 can be a conductive material, such as a metal material, an alloy material, a conductive silicone material, a graphite material, an indium tin oxide, etc.

[0039] In this embodiment, the radiator 300 is disposed on one side of the ground plane 200 and connected to the ground plane 200; the feed source is electrically connected to the radiator 300 and is used to feed current into the radiator 300 so that the radiator 300 radiates the target signal.

[0040] The radiator 300 is used to transmit and receive the target signal. The material of the radiator 300 can be a conductive material, such as a metal, alloy, conductive silicone, graphite, or indium tin oxide. The target signal can be a signal with a target network standard, such as a 4G Long Term Evolution (LTE) signal or a 5G New Radio (NR) signal; or a radio frequency signal with a target frequency band, such as low-frequency, mid-frequency, or high-frequency. The specific type of the target signal is not limited here.

[0041] The radiator 300 is connected to the feed source and is used to feed current through the feed source to excite a magnetic field and radiate the target signal outward. Optionally, the electronic device 10 also includes an antenna PCB (Printed Circuit Board), and the feed source can be disposed on the antenna PCB. Optionally, the feed source can be a device such as an RF chip that provides an excitation signal. The specific feed source can be determined according to actual needs, and this embodiment does not limit it.

[0042] The radiator 300 can be a radiating patch, completely attached to the ground plane 200; or it can be partially attached to the ground plane 200 and partially spaced apart to form an open free end. When the radiator 300 is a radiating patch, its shape is not limited and can be square, rectangular, polygonal, circular, etc. When the radiator 300 has an open free end, it can be an IFA antenna, a T-shaped antenna, etc.

[0043] Optionally, the radiator 300 has a grounding terminal and a free terminal. The grounding terminal is connected to the grounding plate 200, and the free terminal is spaced apart from the grounding plate 200. A feed terminal is provided between the grounding terminal and the free terminal of the radiator 300 for connection to a feed source. The current of the radiator 300 is fed in from the feed terminal, distributed across the radiator 300, and flows from the feed terminal to the free terminal and the grounding terminal, respectively. Further optionally, such as... Figure 5 As shown ( Figure 5 The feed (300 is the center point) and the grounding point, feed, and radiator 300 form an F-type structure. With the feed current, the radiator 300 radiates the target signal in a quarter-wavelength IFA (Invented F Antenna) mode. When the radiator 300 radiates the target signal in IFA mode, the point with the strongest current in the radiator 300 is at the grounding point.

[0044] In this embodiment, the radiation accessory 400 is detachably disposed on the side of the radiator 300 away from the ground plane 200. The radiation accessory 400 is used to radiate under the excitation of the radiator 300 to enhance the radiation efficiency of the target signal in a preset direction.

[0045] The detachable location of the radiator 300 on the side opposite to the ground plane 200 can be understood as the radiating accessory 400 being able to be fixed to the side of the radiator 300 opposite to the ground plane 200, or detached from the radiator 300. Fixing it to the side of the radiator 300 opposite to the ground plane 200 can mean that the distance between the radiating accessory 400 and the radiator 300 is within a preset range; detaching it from the radiator 300 can mean that the distance between the radiating accessory 400 and the radiator 300 exceeds the preset range. The preset range can be the maximum distance at which the radiating accessory 400 can radiate under the excitation of the radiator 300. The specific value can be set according to the material type and radiation mode of the radiating accessory 400 in practice, and is not limited here.

[0046] The decision to fix the radiating accessory 400 to the side of the radiator 300 away from the ground plane 200 or to detach it from the radiator 300 can be determined based on the communication environment of the electronic device 10 or the network information transmitted and received by the radiator 300. For example, the radiating accessory 400 can be fixed to the side of the radiator 300 away from the ground plane 200 when the electronic device 10 is in a weak signal environment such as the edge of a community, deep in a building, or in an elevator, while it can be detached in a strong signal environment. For example, the radiating accessory 400 can be fixed to the side of the radiator 300 away from the ground plane 200 when the network information transmitted and received by the radiator 300 does not meet preset conditions, such as when the signal reception strength of the radiator 300 is less than a certain threshold, while it can be detached when the network information transmitted and received by the radiator 300 meets the preset conditions.

[0047] In this system, the radiator 300 is fed with current under the excitation of the feed source, and the current is distributed on the surface of the radiator 300 to form an electric field, thereby exciting the radiation mode of the radiator 300. When the radiating accessory 400 is disposed on one side of the radiator 300, the radiating accessory 400 is fed with current under the excitation of the radiator 300, and the current is distributed on the surface of the radiating accessory 400 to form an electric field, thereby exciting the radiation mode of the radiating accessory 400. By setting the radiation efficiency of the radiating accessory 400 in a preset direction to be higher than the radiation efficiency in other directions, the radiating accessory 400 can enhance the radiation efficiency of the target signal in the preset direction, thereby improving the overall radiation efficiency of the electronic device 10.

[0048] The radiating accessory 400 is disposed on the side of the radiator 300 facing away from the ground plane 200, thus facing outward relative to the ground plane 200. Specifically, the radiating accessory 400 is disposed on the side of the radiator 300 facing away from the ground plane 200 and located in an area that does not affect the radiation frequency band of the radiator 300, thereby ensuring that the radiating accessory 400 enhances the overall radiation efficiency of the electronic device 10 without affecting the radiation frequency band of the radiator 300. Optionally, the radiator 300 has a grounding terminal and a free terminal, the grounding terminal being connected to the ground plane 200 and the free terminal being spaced apart from the ground plane 200; wherein the radiating accessory 400 is located between the free terminal and the grounding terminal and is close to the grounding terminal. Among them, the free end is the weakest point of current in radiator 300, and the ground return end is the strongest point of current in radiator 300. The ground return end of radiator 300 is equivalent to a short circuit, and the free end is equivalent to an open circuit. Therefore, under the excitation of the feed, the current distribution of radiator 300 is such that the current at the free end is the weakest and the current at the ground return end is the strongest. Therefore, when the radiating component 400 is located between the free end and the ground return end and is close to the ground return end, that is, when it is located at the point with stronger current, it can be ensured that the radiating component 400 is excited by radiator 300 to generate radiation, and the radiation frequency band of radiator 300 is not affected.

[0049] Optionally, such as Figure 5 As shown, the extending direction of the radiating accessory 400 is perpendicular to the radiator 300 and parallel to a preset direction. When the radiating accessory 400 is disposed on one side of the radiator 300, a current is fed into the radiating accessory 400 under the excitation of the radiator 300. The current flows from the radiator 300 to the radiating accessory 400 and is distributed on the surface of the radiating accessory 400. When the extending direction of the radiating accessory 400 is perpendicular to the radiator 300, the current flows from the bottom of the radiating accessory 400 near the radiator 300 to the top of the radiator 300. Therefore, the direction of the current distributed on the radiating accessory 400 is perpendicular to the direction of the current distributed on the radiator 300, making the direction of the electric field formed by the radiating accessory 400 perpendicular to the radiator 300. This effectively improves the overall radiation efficiency of the electronic device 10 and significantly changes the far-field direction of the antenna.

[0050] Optionally, the difference between the length of the radiating accessory 400 in the extension direction and the wavelength of the equivalent medium electromagnetic wave of the radiating accessory 400 is within a preset range. Specifically, the preset range is close to or equal to zero, so that the length of the radiating accessory 400 in the extension direction is close to equal to the wavelength of the equivalent medium electromagnetic wave, so as to radiate effective electromagnetic waves under the excitation of the radiator 300.

[0051] Optionally, the radiating accessory 400 can be a cube, cylinder, or other shaped solid block, as long as the length of the radiating accessory 400 in its extension direction is approximately equal to the wavelength of the equivalent medium electromagnetic wave. The dimensions in other directions can be set according to the actual Industry Design requirements. For example, such as... Figure 6 As shown, the radiating accessory 400 is a cube. The height H of the extending direction of the radiating accessory 400 (i.e., the height of the cube) is approximately the wavelength of the equivalent medium electromagnetic wave. The length L of the bottom surface of the radiating accessory 400 on the side close to the radiator 300 is approximately 1 / 5 of the wavelength of the equivalent medium electromagnetic wave, and the width W is 1 / 8 of the wavelength of the equivalent medium electromagnetic wave.

[0052] Optionally, such as Figure 7 As shown, the number of radiation accessories 400 can be multiple ( Figure 7 (Taking two as an example for illustration), multiple radiating components 400 are spaced apart, and the extension direction of each radiating component 400 is the same. Thus, multiple separate radiating components 400 can simultaneously radiate outwards under the excitation of the radiator 300, further enhancing the radiation efficiency of the target signal in the preset direction, thereby further improving the overall radiation efficiency of the electronic device 10 and further changing the far-field direction of the antenna. The multiple radiating components 400 are not limited to the same size; each radiating component 400 can have a different size; the multiple radiating components 400 can be arranged in an array, for example, in a one-dimensional array.

[0053] Optionally, the radiating accessory 400 is used to radiate in dielectric resonator mode under the excitation of the radiator 300 to enhance the radiation efficiency of the target signal in a preset direction. When the radiating accessory 400 radiates in dielectric resonator mode, it forms a dielectric resonator mode antenna, which can radiate through the surface of the radiating accessory 400. Since there is no conductor and surface wave loss and the dielectric itself has low loss, the radiating accessory 400 has high radiation efficiency, which can effectively improve the overall radiation efficiency of the electronic device 10. In addition, when the radiating accessory 400 radiates in dielectric resonator mode and the radiator 300 radiates in a quarter-wavelength mode, since the radiating accessories 400 and the radiator 300 have different radiation modes, the electronic device 10 radiates in two modes, which can expand the radiation bandwidth. When there are multiple radiating accessories 400, multiple radiating accessories 400 are excited to generate multiple dielectric resonator modes, which can further effectively improve the overall radiation efficiency of the electronic device 10 and expand the radiation bandwidth.

[0054] Optionally, the material of the radiating accessory 400 is a dielectric material with a high dielectric constant, such as glass, plastic, or ceramic, so that the radiating accessory 400 can radiate in dielectric resonator mode under the excitation of the radiator 300. Further optionally, the relative dielectric constant of the radiating accessory 400 is greater than 10, so that the radiating accessory 400 forms an effective dielectric resonator antenna, effectively increasing the overall antenna efficiency of the electronic device 10.

[0055] The following example uses a radiator 300 as a low-frequency IFA antenna operating at a resonant frequency of 0.792 GHz. The comparison will be made between a first electronic device excluding the radiating component 400 and an electronic device including the radiating component 400 in this embodiment (e.g.,...). Figure 8 A comparison of the communication capabilities of the second electronic device (using the radiating accessory 400 with a relative permittivity εr of 20 as an example) shown in the embodiment is illustrated below:

[0056] Please refer to the assistance provided. Figures 9-11 , Figure 9 , Figure 10 , Figure 11 The graphs show the reflection coefficient curve, radiation performance diagram (solid line for radiation efficiency, dashed line for overall system efficiency), and far-field radiation pattern of the first electronic device. Figure 9 It can be seen that the reflection coefficient curve S11 of the first electronic device is <-4dB (762~822MHz); from Figure 10 It can be seen that the overall system efficiency of the first electronic device ranges from -9.8 to -7.6 dB, with an average of -8.7 dB. Overall system efficiency represents the communication performance of the electronic device; better overall system efficiency enables a longer communication range and faster data rates.

[0057] Please refer to the assistance provided. Figures 12-14 , Figure 12 , Figure 13 , Figure 14 These are the reflection coefficient curve, radiation performance diagram, and far-field radiation pattern of the second electronic device. From... Figure 8 It can be seen that after the radiating accessory 400 is installed, a certain electric field is distributed along the x-axis on the radiating accessory 400. The electric field distribution on the mobile phone accessory has a significant effect, greatly changing the far-field radiation pattern of the second electronic device: from Figure 14 and Figure 11 The comparison shows that, compared to the first electronic device, the far-field radiation pattern of the second electronic device's antenna completely transforms into a zero-point radiation pattern along the x-axis. This indicates that the radiation mode of the radiating component 400 accounts for a large proportion of the overall radiation of the second electronic device, effectively improving antenna efficiency. From Figure 12It can be seen that after setting the radiating accessory 400, the reflection coefficient curve S11 of the second electronic device is <-4dB (765~845MHz), and the operating bandwidth is widened; from Figure 13 It can be seen that the overall system efficiency of the second electronic device is between -6.2 and -3.6 dB, with an average of -4.3 dB. Compared with the first electronic device, the overall system efficiency of the second electronic device is improved by 4.5 dB, which is a very significant improvement.

[0058] Therefore, the radiating accessory 400, as an effective supplementary accessory to the electronic device 10, is detachably located on the side of the radiator 300 away from the ground plane 200. It will not degrade the operating bandwidth of the radiator 300, but will instead greatly improve the communication performance of the electronic device 10.

[0059] The electronic device 10 provided in this embodiment includes a ground plane 200, a radiator 300, a feed source, and a radiating accessory 400. The radiator 300 is disposed on one side of the ground plane 200 and connected to it. The feed source is electrically connected to the radiator 300 and is used to feed current into the radiator 300 so that the radiator 300 radiates the target signal. The radiating accessory 400 is detachably disposed on the side of the radiator 300 away from the ground plane 200. The radiating accessory 400 is used to radiate under the excitation of the radiator 300 to enhance the radiation efficiency of the target signal in a preset direction. As an effective supplementary accessory to the electronic device 10, the radiating accessory 400, detachably disposed on the side of the radiator 300 away from the ground plane 200, effectively increases the overall antenna efficiency of the electronic device 10 under the excitation of the radiator 300, enabling the electronic device 10 to have a longer communication range and a faster communication data rate.

[0060] like Figure 15 As shown, the electronic device 10 provided in this application embodiment also includes a middle frame 12 ( Figure 15 (The radiator 300 is illustrated using an IFA antenna as an example). The middle frame 12 includes an interconnected frame 120 and a middle plate 130. The middle plate 130 has a ground plane 200, and the frame 120 has a radiator 300. The ground plane 200 in the middle plate 130 can be understood as a portion of the middle plate 130 serving as the ground plane 200, or the middle plate 130 itself serving as the ground plane 200. The radiator 300 in the frame 120 can be understood as a portion of the frame directly serving as the radiator 300, or the frame having a slit to form the radiator 300.

[0061] The frame 120 includes a top frame 121 and a bottom frame 123 disposed opposite to each other, and a first side frame 122 and a second side frame 124 connected between the top frame 121 and the bottom frame 123. A radiator 300 is formed on at least one of the top frame 121, the bottom frame 123, the first side frame 122, and the second side frame 124. The radiating accessory 400 can be detachably disposed on the top frame 121, the bottom frame 123, the first side frame 122, and the second side frame 124, and can be detachably disposed on the side of the radiator 300 away from the ground plane 200.

[0062] Optionally, such as Figure 16 As shown, the radiating accessory 400 may have a recessed portion that is detachably fitted onto the frame 120 and corresponds to the position of the radiator 300, located on the side of the radiator 300 facing away from the ground plane 200. By fitting the recessed portion onto the frame 120, no additional auxiliary components are required, which helps to save costs and improve the ease of use for the user.

[0063] Optionally, the radiating accessory 400 can also be attached to the frame 120 by an adsorbent, wherein the adsorbent is located in the area of ​​the frame 120 where the radiator 300 is not provided, and the adsorbent detachably fixes the radiating accessory 400 to the side of the radiator 300 away from the grounding plate 200 by adsorption.

[0064] Optionally, the radiating accessory 400 can also be detachably mounted on the side of the radiator 300 away from the ground plane 200 via a movable connector such as a spring. For example, one end of the movable connector is mounted on the frame 120, and the other end is mechanically connected to the radiating accessory 400. This allows the movable connector to be moved via a control circuit or manually controlled by the user, thereby causing relative movement between the radiating accessory 400 and the radiator 300, and controlling the distance between the radiating accessory 400 and the radiator 300 to be within or exceed a preset range.

[0065] Optionally, the radiating accessory 400 can also be disposed on the housing, detachably mounted on the mid-frame of the electronic device 10 via the housing, so as to be detachably mounted on the side of the radiator 300 facing away from the ground plane 200. Further optional, such as Figure 17As shown, the radiating accessory 400 is embedded in the housing 20. This embedding can be achieved by the housing 20 having a groove or slot in the area corresponding to the radiator to accommodate the radiating accessory 400, or by the radiating accessory 400 being integrally formed with the housing 20. When the radiating accessory 400 is embedded in the housing 20 through the groove or slot, it can be permanently fixed to the housing 20 or detachably mounted on the housing 20. The housing 20 is detachably mounted on the middle frame 12 of the electronic device 10. This can be understood as the housing 20 being located solely on the middle frame 12, or it can be understood as being located on the middle frame 12 of the electronic device 10 and simultaneously enclosing the cover assembly 13 of the electronic device 10 (see also [reference]). Figures 1-3 ).

[0066] The outer casing 20 can be a casing with both aesthetic and protective functions. For example, when the electronic device 10 is a mobile phone, the outer casing 20 can be a mobile phone protective case.

[0067] It is understood that in other embodiments, the radiating accessory 400 may also be detachably fixed to the side of the radiator 300 away from the grounding plate 200 by other auxiliary accessories, without further limitation.

[0068] Optionally, the electronic device 10 also includes a prompting circuit, which is disposed on the middle plate 130, for acquiring network information of the radiator 300 transmitting and receiving target signals, and generating a prompting signal when the network information does not meet preset conditions. The prompting signal is used to prompt the target object to place the radiating accessory 400 on the electronic device 10.

[0069] The target object can be a user, and the prompt signal can be an audio-visual prompt signal, image signal, etc. from the electronic device 10. When the user receives the prompt signal, they can manually place the radiation accessory 400 on the electronic device 10. Optionally, the prompt circuit can also generate a disassembly signal when the network information meets preset conditions to prompt the user to remove the radiation accessory 400 from the electronic device 10.

[0070] The target object can be auxiliary control components located inside or outside the electronic device 10. These auxiliary control components are connected to the prompting circuit and the radiating accessory 400. When the auxiliary control component receives a prompting signal, it controls the distance between the radiating accessory 400 and the radiator 300 to be within a preset range, thus placing the radiating accessory 400 on one side of the radiator 300. Optionally, the prompting circuit can also generate a disassembly signal when network information meets preset conditions. The auxiliary control component then controls the distance between the radiating accessory 400 and the radiator 300 to exceed the preset range, thus detaching the radiating accessory 400 from the radiator 300. The preset range is described in the relevant description in the above embodiments and will not be repeated here.

[0071] The network information may include raw and processed information associated with wireless performance metrics when the radiator 300 transmits and receives target signals, such as signal strength, received power, reference signal receiving power (RSRP), received signal strength indicator (RSSI), signal to noise ratio (SNR), carrier to interference plus noise ratio (RS-CINR), frame error rate, bit error rate, and reference signal reception quality (RSRQ).

[0072] Taking network information as an example of received signal strength, if the signal strength of the low-frequency signals transmitted and received by the radiator 300 is lower than a preset threshold within a preset time period, a prompt signal is generated to prompt the target object to place the radiating accessory 400 on the electronic device 10. The preset threshold can be set as needed.

[0073] The electronic device 10 provided in this embodiment includes a ground plane 200, a radiator 300, a feed source, a radiating accessory 400, and a middle frame 12 as described in the above embodiment. The middle frame 12 includes an interconnected frame 120 and a middle plate 130. The middle plate 130 forms the ground plane 200, and the frame 120 forms the radiator 300. Since the radiating accessory 400, as an effective supplementary accessory, is detachably located on the side of the radiator 300 away from the ground plane 200, under the excitation of the radiator 300, the overall antenna efficiency of the electronic device 10 is effectively increased. Therefore, the electronic device 10 has higher signal transmission and reception performance, a longer communication range, and a faster communication data rate.

[0074] like Figure 18 As shown, further explanation will be given using mobile phone 30 as an example for electronic device 10. Specifically, as follows... Figure 18 As shown, the mobile phone 30 may include a memory 21 (which optionally includes one or more computer-readable storage media), a processor 22, a peripheral device interface 23, a radio frequency system 24, and an input / output (I / O) subsystem 26. These components optionally communicate via one or more communication buses or signal lines 29. Those skilled in the art will understand that... Figure 18The mobile phone 11 shown does not constitute a limitation on the mobile phone and may include more or fewer components than shown, or combine certain components, or have different component arrangements. The various components shown in the figure are implemented in hardware, software, or a combination of both, including one or more signal processing and / or application-specific integrated circuits.

[0075] Memory 21 optionally includes high-speed random access memory, and also optionally includes non-volatile memory, such as one or more disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Exemplary examples include software components stored in memory 21 such as an operating system 211, a communication module (or instruction set) 212, a global positioning system (GPS) module (or instruction set) 213, etc.

[0076] Processor 22 and other control circuits (such as the control circuits in the radio frequency system 24) can be used to control the operation of mobile phone 11. The processor 22 may be based on one or more microprocessors, microcontrollers, digital signal processors, baseband processors, power management units, audio codec chips, application-specific integrated circuits, etc.

[0077] The processor 22 can be configured to implement control algorithms for controlling the use of the antenna in the mobile phone 11. The processor 22 can also issue control commands for controlling various switches in the radio frequency system 24.

[0078] I / O subsystem 26 couples input / output peripherals on mobile phone 11, such as a keypad and other input control devices, to peripheral interface 23. I / O subsystem 26 optionally includes a touchscreen, buttons, a tone generator, an accelerometer (motion sensor), an ambient light sensor and other sensors, LEDs and other status indicators, data ports, etc. For example, a user can control the operation of mobile phone 11 by supplying commands via I / O subsystem 26, and can use the output resources of I / O subsystem 26 to receive status information and other outputs from mobile phone 11. For example, a user can press button 261 to turn the phone on or off.

[0079] The radio frequency system 24 may include the radiator and radiating accessories of any of the foregoing embodiments.

[0080] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0081] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
