Description

[Technical Field]

[0001] (CROSS-REFERENCE TO RELATED APPLICATIONS) This disclosure is based on and claims priority from Chinese patent application CN2023102482050, filed on March 8, 2023, for the invention entitled "Terminal antenna adjustment method, device, storage medium, and electronic device," the entire contents of which are incorporated herein by reference.

[0002] TECHNICAL FIELD Embodiments of the present disclosure relate to the field of communications, and more particularly to a method, apparatus, storage medium and electronic device for adjusting a terminal antenna. [Background technology]

[0003] The coordinate energy distribution diagram of the electromagnetic radiation field of a WIFI antenna in all directional space is called a directional diagram. Here, it is further divided into total radiated power (TRP) and total isotropic sensitivity (TIS) directional diagrams. A diagram showing the radiated field strength is called a field strength directional diagram, and a diagram showing the power density is called a power directional diagram. A WIFI directional diagram can show the distribution of antenna gain in each WIFI direction.

[0004] The WIFI radiation direction determines the direction in which WIFI will be directed to optimize performance and maximize coverage. The stronger the signal, the higher the protocol method (e.g., 802.11b / g / a / n / ac / ax) assigned by the router to the terminal, the higher the assigned MCS rate, and the higher the final WIFI transmission throughput. In related technologies, the WIFI operating channel and frequency band are always relatively fixed and cannot be dynamically switched or adjusted, and at the same time, they cannot compensate for the defect problem of poor directionality.

[0005] The related art has not yet provided a solution to the problem that the WIFI operating channel and frequency band are always relatively fixed, cannot be dynamically switched and adjusted, and at the same time cannot compensate for poor directionality.

Taking the implementation in a computer device as an example, Figure 1 is a hardware structural block diagram of a computer device for the terminal antenna adjustment method of the embodiments of the present disclosure. As shown in Figure 1, the computer device may include one or more (only one is shown in Figure 1) processors 102 (the processor 102 may include, but is not limited to, a processing device such as a microprocessor MCU or a programmable logic device) and a memory 104 for storing data, wherein the computer device may further include a transmission device 106 and an input / output device 108 for communication functions.

For example, the computer device may include more or fewer components than those shown in Figure 1, or have a different configuration than the components shown in Figure 1.

[0016] The memory 104 can be used to store computer programs, such as software programs and modules of application software.

[0018] The transmission device 106 is used to receive or transmit data via a network. A specific example of the network is a wireless network provided by a carrier of the computer device. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, NIC), which can connect to other network devices via a base station and communicate with the Internet. In one example, the transmission device 106 may be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0019] This embodiment provides a terminal antenna adjustment method executed by the above-mentioned computer device. FIG. 2 is a flowchart of the terminal antenna adjustment method according to the embodiment of the present disclosure. As shown in FIG. 2, the flow includes: Step S202 of collecting signal quality conditions on each channel path of the terminal antenna; Step S204: detecting an obstacle in the transmission direction of the terminal antenna; Step S206: acquiring relative position information of the terminal antenna with respect to the router; and adjusting terminal antenna radiation based on at least one of signal quality conditions, obstacles, and the relative position information.

[0020] The above steps S202 to S208 solve the problem in the related art that the WIFI operating channel and frequency band are always relatively fixed and cannot be dynamically switched and adjusted, and at the same time, cannot compensate for poor directionality. Therefore, the WIFI antenna can self-adaptively adjust its radiation direction and connect to the router with the optimal radiation antenna and path, thereby strengthening the WIFI signal strength and improving the user's WIFI usage experience.

[0021] In an embodiment of the present disclosure, the above step S208 may specifically include S2081 and S2082.

[0022] In S2081, determine an active antenna of the terminal antenna based on at least one of a signal quality condition, an obstacle, and the relative position information, where the active antenna is a single antenna or an antenna combination.

[0023] Furthermore, S2081 may specifically include the steps of obtaining an omnidirectional direction diagram of the terminal antenna from a pre-established direction diagram database, determining a current direction diagram of the terminal antenna from the omnidirectional direction diagram based on the signal quality state and / or relative position information, and determining an operating antenna of the terminal antenna based on the current direction diagram, or determining an antenna in a transmission channel with the strongest signal strength as the operating antenna by switching antennas in each transmission channel of the terminal antenna based on at least one of the signal quality state, obstacles, and relative position information.

[0024] In S2082, the terminal antenna is adjusted by the operational antenna so that the signal quality state of the terminal antenna meets a preset condition.

[0025] Furthermore, S2082 specifically states: Controlling the terminal antenna to switch to the active antenna; If the signal quality status of the terminal antenna satisfies the preset condition after switching to the working antenna, terminating the adjustment of the terminal antenna; If the signal quality status of the terminal antenna does not satisfy the preset condition after switching to the active antenna, adjusting the radiation direction of the active antenna's directional diagram based on the parasitic effect and / or coupling effect of the directional diagram of the active antenna; If the signal quality status of the terminal antenna satisfies the preset condition after adjusting the radiation direction of the operational antenna to the direction diagram, terminating the adjustment of the terminal antenna; If the signal quality status of the terminal antenna does not satisfy the preset condition after adjusting the radiation direction of the operational antenna to the direction diagram, the method may include switching the radiation mode of the operational antenna and terminating the adjustment of the terminal antenna, wherein the radiation mode includes an omnidirectional radiation mode and a directional radiation mode.

[0026] In one embodiment, the step of adjusting the radiation direction of the directional diagram of the active antenna based on the parasitic effect of the directional diagram of the active antenna may specifically include at least one of the following steps: adding a tuning switch or a slot length variable control unit to each antenna to change the directional diagram corresponding to the active antenna; adjusting the directional diagram on the ground feed by a variable element whose directional diagram is changed; and adjusting the radiation direction of the directional diagram by turning on / off a resistance-capacitance-impedance tuning element on the main signal feed point path and changing the resistance-capacitance-impedance value.

[0027] In one embodiment, the step of adjusting the radiation direction of the direction diagram of the operational antenna based on the coupling effect of the direction diagram of the operational antenna may specifically include a step of forming a new direction diagram of the operational antenna by changing at least one of the power, signal strength, and orientation of the direction diagram of the operational antenna.

[0028] In another embodiment, the step of switching the radiation mode of the operating antenna may specifically include a step of controlling the radiation mode to an omnidirectional radiation mode when the location of the router to which the terminal is connected is unknown or the terminal is in an initial connection, and / or a step of controlling the radiation mode to switch to a directional radiation mode when the terminal has already recognized the location of the router to which it is currently attempting to connect and the signal strength of the router is less than a third preset threshold.

[0029] In one alternative embodiment, the method further includes a step of selecting an optimal terminal antenna direction diagram and direction diagram radiation mode based on connection data between the terminal antenna and a preset router, and / or a step of adjusting the terminal antenna direction diagram by performing at least one of direction testing, direction selection, and direction adjustment multiple times, respectively, to form an omnidirectional direction diagram of the terminal antenna, and storing the omnidirectional direction diagram in a direction diagram database.

[0030] In an embodiment of the present disclosure, the above step S202 may specifically include a step of collecting signal quality status in real time on each channel path of the terminal antenna via a baseband chip and an antenna chip connected to the baseband chip, where the signal quality status includes at least one of an uplink and downlink throughput rate, a received signal strength indication (RSSI for short), a bit error rate, and a signal to noise ratio (SNR for short).

[0031] In an embodiment of the present disclosure, the above step S206 specifically includes the steps of: collecting terminal location information at a preset time period; determining a distance difference between the location information collected at the current time period and the location information collected at the previous time period; and, if the distance difference is greater than the preset distance, determining that the terminal antenna has changed its position relative to the router; and generating and acquiring location change information, wherein the relative location information includes the location change information; or obtaining the terminal's current location and the initial location when the terminal connects to the router; determining the distance and direction between the current location and the initial location; and determining and acquiring the relative position and relative direction between the terminal antenna and the router based on the distance and direction according to the omnidirectional direction diagram of the terminal antenna; wherein the relative location information includes the relative position and relative direction.

[0032] In an embodiment of the present disclosure, the above step S204 may specifically include S2041 and S2042.

[0033] In S2041, an obstacle in the transmission direction of the terminal antenna is detected by an obstacle proximity detection method.

[0034] Furthermore, the above step S2041 may specifically include the steps of detecting whether an interference or interference signal source exists at the terminal antenna within a predetermined distance range, and if an interference or interference signal source exists, determining that an obstacle exists at the terminal antenna in the transmission direction, and if an interference or interference signal source does not exist, determining that no obstacle exists at the terminal antenna in the transmission direction; and sending a charge signal to a router, the charge signal being radiated by the corresponding terminal antenna and returned after encountering an obstacle, and if the charge signal returned from the router is detected, determining that an obstacle exists at the terminal antenna in the transmission direction, and if the charge signal returned from the router is not detected, determining that no obstacle exists at the terminal antenna in the transmission direction.

[0035] In S2042, an obstacle in the transmission direction of the terminal antenna is detected by a method of remote obstacle detection.

[0036] Furthermore, the above step S2042 may specifically include the steps of: determining a time difference between a signal sent to the router and a signal returned from the router; and, based on the difference value between the time difference and a theoretical time difference in a predetermined obstacle-free state, determining that an obstacle exists at the terminal antenna in the transmission direction if the difference value is greater than or equal to a first preset threshold, and determining that no obstacle exists at the terminal antenna in the transmission direction if the difference value is less than the first preset threshold; and determining an attenuation difference between the signal strength of the signal sent from the router and a theoretical signal strength in a predetermined obstacle-free state if the attenuation difference is greater than or equal to a second preset threshold, and determining that no obstacle exists at the terminal antenna in the transmission direction if the attenuation difference is less than the second preset threshold.

[0037] The direction diagram in this embodiment refers to a coordinate energy distribution map of the electromagnetic radiation field of the terminal antenna in omnidirectional space, and the direction diagram of each direction of the terminal antenna is called an omnidirectional direction diagram.

[0038] Specifically, the terminal antenna described above may be a WIFI antenna or another antenna, and the following describes in detail an embodiment of the present disclosure using a WIFI antenna as an example.

[0039] This embodiment mainly solves the problem of terminal WIFI directionality. Based on the terminal's azimuth position relative to the router and the surrounding environmental conditions, the direction and direction diagram of the terminal's WIFI antenna are changed in real time. Specifically, by monitoring the terminal's WIFI throughput and bit error status, it is determined whether the current WIFI quality problem is due to directionality, and a terminal WIFI direction diagram model is established and configured in real time.

[0040] The system tests the relative position and direction between the terminal WiFi and the router, adjusts the antenna direction to improve throughput, detects the user's handheld and nearby / far obstacles, and uses directional interference-resistant detection technology to resolve both near and far WiFi interference and obstacles, detecting and avoiding influential objects. The system reconfigures the terminal's multi-input / multi-output (MIMO) WiFi antenna direction diagram to orient the terminal WiFi's maximum gain radiation direction toward the router, and uses an antenna direction diagram coupling algorithm to change the WiFi antenna direction diagram. A direction diagram parasitic adjustment algorithm realizes direction diagram adjustment for different directional positions.

[0041] The omnidirectional directional adjustment algorithm of the direction diagram solves the problem of the current small scanning angle of the direction diagram. Two WIFI front-end modules are switched in N directions, reducing blind spots and improving the real-time dynamic WIFI throughput performance of the terminal. The relative position and direction of the terminal and router are tracked in real time, self-adaptively adjusted, and dynamically adjusted in real time to align the direction.

[0042] FIG. 3 is a system structure diagram of a 5G terminal device with WIFI dynamic directionality adaptation according to an embodiment of the present disclosure. As shown in FIG. 3, the mobile terminal includes: a WIFI antenna status collection module L1, a direction measurement and mapping module L2, a direction scanning and selection module L3, a near-far interference detection module L4, a WIFI direction control module L5, a multi-WIFI antenna expansion module L6, a direction diagram antenna selection adjustment module L7, a direction diagram parasitic adjustment module L8, a direction diagram coupling adjustment module L9, a direction diagram omnidirectional direction switching module L10, a direction diagram dynamic tracking module L11, and a direction diagram database establishment module L12.

[0043] 4 is a schematic diagram of WIFI antenna status collection according to an embodiment of the present disclosure. As shown in FIG. 4, the WIFI antenna status collection module L1 is connected to the WIFI direction scanning and selection module L3 and is configured to collect the status and signal quality status of each MIMO antenna of the terminal WIFI 2.4G / 5G / 6G, including the signal strength of each WIFI channel path, such as RSSI value, or performance parameters of each channel, such as throughput rate, bit error rate, SNR signal-to-noise ratio, etc.

[0044] The collected values ​​of the antenna status and signal quality status are collected in real time through the mobile phone baseband chip and the WIFI chip connected thereto, and each reported value is captured, and the antenna status includes the above parameter values ​​of the antenna status of multiple MIMO paths of CH0 / CH1 / CHn.

[0045] FIG. 5 is a schematic diagram of WIFI antenna direction diagram testing and orientation mapping according to an embodiment of the present disclosure. As shown in FIG. 5, the direction measurement and mapping module L2 is connected to the direction scanning and selection module L3 and configured to test the direction of the terminal WIFI antenna, and the WIFI antenna path sequence forms a mapping table, which is easy to call.

[0046] The direction diagram of each WIFI antenna on the terminal under test is tested and stored in the WIFI direction diagram database. The testing and sorting mapping steps are as follows:

[0047] The directional diagram of the WIFI antenna is obtained by testing in an OTA darkroom before shipment, and the control module controls the terminal to switch between the WIFI antenna and antenna path, forming multiple signals and antenna paths S1, S2, ... Sn, and each path tests a complete omnidirectional 360-degree directional diagram F1, F2 ... Fn.

[0048] In each direction diagram, values ​​and directions that meet a certain strength, such as ERP and EIS values, exceeding a certain threshold requirement are filtered out.

[0049] ERP and EIS, direction values, and WIFI antenna path sequences are organized into a mapping table for easy recall.

[0050] The WIFI direction scanning and selection module L3 is connected to the WIFI direction control module L5, and is configured to test and select the strongest direction of the terminal WIFI antenna and the connected router. The position of the WIFI router connected to the terminal WIFI is relatively fixed, but as the user's position moves and the way the user holds the terminal changes, the position of the terminal WIFI is constantly moving, that is, the direction of different use points is different, and even at the same position, the direction diagram for different orientations is different. Even at the same location, the same orientation, and different near and far contact objects and obstacles, the direction diagram is variable.

[0051] However, due to the limitations of the WIFI antenna itself, both the AP and station terminal antennas have a certain directionality. The characteristics of WIFI directionality are as follows: the directional diagram of a WIFI antenna is omnidirectional, not a regular spherical pattern, meaning that the signal is strong in some directions and weak in others. If the antenna directional diagram of the terminal WIFI antenna and the router are far apart, the WIFI signal will be weak; if the antenna directional diagram of the terminal WIFI antenna and the router are aligned and have a certain orthogonal relationship, the WIFI signal will be strongest.

[0052] The purpose of the WIFI direction scanning and selection module L3 is to measure the directionality of the terminal and the router. Figure 6 is a schematic diagram of the WIFI antenna direction scanning and selection according to an embodiment of the present disclosure, where two measurement methods are adopted, as shown in Figure 6.

[0053] Scanning test method: The software controls the WIFI antenna to operate at different positions, achieving omnidirectional scanning of the direction diagram in each direction and angle. The distributed antenna on the terminal divides different WIFI antennas into different areas and angles. Each antenna is disconnected in turn, and a WIFI signal is sent to the target router. The strength of the received signal is used to determine which antenna direction diagram on the terminal WIFI the target router is closest to, thereby obtaining an initial rough direction. The antenna combination adjustment policy is then used to change the direction diagram's deflection and determine the optimal position for a more specific direction diagram.

[0054] Relative positioning test method: When a WIFI terminal starts connecting with a router, the terminal approaches an access point (abbreviated as AP), and the mobile phone terminal records the AP's location information A, such as latitude and longitude. When the mobile phone moves to position B, the terminal records the latitude and longitude information of position B. The positioning test module measures the distance and direction between the two points A and B. If the direction does not match the maximum radiation direction of the WIFI terminal, it will switch the control module and change the direction of the current direction diagram, so that the strongest signal direction is always maintained.

[0055] The near-far interference detection module L4 is connected to the WIFI directional control module L6 and the direction scanning and selection module L3, and is set to detect obstacles in the WIFI maximum transmission direction. Here, it is divided into two modes: near detection and far detection. When an obstacle is detected in a certain direction, the radiation direction needs to be switched and changed.

[0056] Directional diagram obstacle proximity detection method: This method detects whether there is an interference or obstruction signal source within a certain distance range (e.g., 0.3 meters, 0.5 meters, 1 meter, etc.) around the terminal WIFI antenna. For example, the interference or obstruction signal source is blocked by the user's hand, a metal object, or the user's body. The directional diagram proximity detection method uses SAR (Successive Approximation Register, a successive approximation analog-to-digital converter) reduction signal detection in multiple directions on the terminal. When it detects that the user is holding something in their hand or that another object is approaching, it triggers a change in the SAR signal, and the module can determine that there is an obstacle in that direction.

[0057] Here, the ground / power point of each WIFI antenna on the terminal is connected to each channel of the SAR chip, and the SAR chip adopts a multi-channel design, such as 1:3 connection or 1:4 connection. If there are currently four WIFI antennas in total, only one 1-input 4-output SAR chip is required. If there are currently eight main candidate antennas on the terminal, two 1-input 4-output SAR chips are used.

[0058] When WIFI is in operation, it sends a charge signal to the SAR chip, which then radiates it through the corresponding WIFI metal or flexible printed circuit (FPC) antenna. After encountering an obstacle, the charge signal is returned and received by the corresponding WIFI antenna, and then returned to the SAR chip through the connecting line on the board for detection and statistics, thereby realizing obstacle detection in the direction of the corresponding WIFI antenna.

[0059] Directional Diagram Obstacle Remote Detection Method: In the WIFI communication process, multiple antennas are used for data transmission, and one antenna is used for obstacle detection in a specific direction, where two detection methods are used.

[0060] The first is a time difference calculation method, in which the distance AB between the WIFI terminal and the connected router AP is known, and the time difference t1 between the transmitted signal and the router reply signal is calculated by comparing it with the theoretical time difference for an obstacle-free area, t2. If there is an obstacle in that direction, t2 > t1, and the thicker and more numerous the obstacles are, the larger the difference value between the two, t1 - t2 = Δt.

[0061] The second is the attenuation difference calculation method. Figure 7 is a schematic diagram of a WIFI antenna scanning near and far obstacles according to an embodiment of the present disclosure. As shown in Figure 7, when a WIFI signal from a terminal is transmitted over medium to long distances, the attenuation value of different materials is different, and the higher the frequency, the greater the attenuation. At the same time, it can be divided into free space loss and physical material loss, of which physical material loss can be further divided into human body loss, wall loss, wood material loss, metal material loss, glass material loss, etc.

[0062] At the same time, this module also includes terminal WIFI electromagnetic interference detection, which means that when WIFI is operating, it needs to stay away from other electromagnetic signals with the same frequency, adjacent frequencies, and harmonic and intermodulation relationships, such as Bluetooth, microwave ovens, computers, televisions, high-voltage lines, mobile phones, tablet computers (Portable Android Devices, abbreviated as PAD), and other electronic devices such as WIFI and routers. Therefore, the avoidance mechanism of the terminal WIFI direction diagram designed in this design also needs to avoid these interference obstacles to prevent WIFI signals from being interfered with.

[0063] The L5 WIFI directional control module is connected to the direction diagram database module L12, the near-far interference scanning module L4, and the direction adjustment control modules L7 to L11, and controls the WIFI antenna through software to operate at different positions, realizing omnidirectional scanning of the direction diagram. The directional control module controls the operation of the following parts:

[0064] The number of active WIFI antennas is controlled based on the uplink and downlink throughput and other signal quality parameters.

[0065] Based on the uplink and downlink throughput and other signal quality parameters, an optimal direction diagram direction is selected to control one or more WIFI antennas.

[0066] Control mode based on antenna direction diagram switching: Controls the primary and secondary order of ch0, ch1, ch3...chn combinations in MIMO antennas based on uplink / downlink throughput and other signal quality parameters. For example, if a mobile phone has multiple WIFI antennas, the combinations, i.e., which is the primary antenna and which is the secondary antenna, can be switched and changed. That is, by channel switching between WIFI front-end modules, the order of different WIFI primary and secondary antennas and MIMO antennas can be switched, thereby reconfiguring the antenna direction diagram.

[0067] Control mode based on direction diagram reconfiguration: Based on the current application program, business needs, and throughput needs, the direction diagram is reconfigured based on the business. The terminal WIFI throughput can be divided into upstream upload throughput, downstream download throughput, and two-way mutual transmission throughput. The upstream and downstream direction diagrams are reconfigured based on the current business needs.

[0068] WIFI-based direction fine-tuning mode: After selecting the WIFI antenna, WIFI path, and WIFI direction diagram, if the current signal is not the strongest or there are still obstacles in the transmission path, you can select the direction diagram fine-tuning mode to make precise and fine adjustments to the WIFI antenna direction diagram. The WIFI antenna direction diagram adjustment control sequence is shown in Table 1.

[0069] [Table 1]

[0070] The multi-WIFI antenna extension module L6 is connected to the direction measurement and mapping module L2 and configured as a WIFI MIMO antenna extension. WIFI antenna extension can be divided into two ways:

[0071] The first is the expansion of the number of antennas, with 2-N WIFI antennas distributed on the terminal. The directional diagram orientation of each WIFI antenna is combined, and the antenna distribution layout with different orientations enables WIFI signals to be transmitted in all directions with no blind spots.

[0072] There are N antennas distributed above, below, left, and right of the mobile phone, each corresponding to one of the strongest directions. Here, some antennas are independent channel antennas, and some antennas are multiplexed with antennas of other frequency bands, for example, one WIFI antenna is parasitic on an LTE / NR antenna.

[0073] The second is the expansion of antenna positions. For example, WIFI includes four antennas, each corresponding to one WIFI frequency band and channel. The traditional solutions are relatively independent. Here, different WIFI antennas are interconnected by DPDT, 3P3T, 4P4T, nPnT to form different switching and intercommunication links, thereby realizing the expansion of antenna paths.

[0074] The third is the expansion of the front-end FEM. For example, WIFI includes four MIMO channels, CH0, CH1, CH2, and CH3. Each of the original channels corresponds to a PA / LNA front-end module. Naturally, it may include one of the PA / LNAs, or it may be a front-end module that only includes a filter and a switch and does not include a PA / LNA. The WIFI antenna is connected to the WIFI chip through these front-end FEM modules. The traditional solution is one-to-one, but here, a multi-input multi-output switch, such as DPDT, 3P3T, or 4P4T, is used to connect the inputs of these modules to the TX / RX output ports of the WIFI chip, forming an intercommunication state. Each FEM corresponds to an antenna, enabling intercommunication and switching between antennas with different orientations.

[0075] The directional diagram antenna selection and adjustment module L7 is connected to the WIFI direction control module L6 and is configured to self-adaptively adjust the WIFI antenna directional diagram on the terminal, so that the WIFI signal on the terminal and the router can align to maximize the radiation direction. That is, it selects the optimal single antenna or antenna combination from multiple WIFI MIMO (multiple-input, multiple-output) antennas, and maximizes directional diagram adaptation and switching. The directional diagram adjustment can adjust the directional diagram of a single antenna, changing the displayed current distribution of a single WIFI antenna through antenna structure matching, resonance, or parasitic changes, thereby realizing a change in the radiation direction of the directional diagram. The directional diagram adjustment can also change the system directional diagram corresponding to multiple MIMO antennas.

[0076] The direction diagram parasitic adjustment module L8 is connected to the WIFI direction control module L6 and is set to adjust the direction radiation based on the direction diagram parasitic effect.

[0077] The directional diagram adjustment method for each WIFI antenna is to add a tuning switch or slot length variable control unit to each antenna to change the directional diagram of the corresponding WIFI antenna, that is, to realize the control adjustment that can change the maximum gain directional diagram in three-dimensional space, and change the strongest gain radiation direction of a single WIFI antenna, which can be further divided into two operating modes: the first is a mode in which the directional diagram is changed but the center frequency is not changed, and the second is a mode in which the directional diagram is changed and the center frequency is also changed, that is, the directional diagram adjustment method in which the electrical length of the slot antenna or FPC antenna in the terminal is changed.

[0078] WIFI Direction Diagram Change Method 2: Parasitic Adjustment Method: The WIFI antenna path of the terminal is modified by adding a directional diagram and changing the elements, and the metal frame of the terminal is divided into different sections and paragraphs through slots, each section corresponds to one antenna direction, the lower left section corresponds to the lower left direction, and the upper right section corresponds to the upper right section.

[0079] The variable element whose direction diagram is changed may be an SP4T tuning switch or a MEMS tuning switch, which performs direction diagram adjustment on the ground feed, or may be a resistance-capacitance-impedance tuning element on the main signal feed point path, and by turning on and off the different architectures and changing the resistance-capacitance-impedance values, it is possible to realize direction diagram radiation direction adjustment with variable maximum gain direction.

[0080] Taking a metal frame WIFI antenna as an example, if the terminal WIFI needs to change the direction diagram, it can simply change the antenna gap between on and off, which will change the surface current density of the WIFI antenna and simultaneously change the direction of the surface current, thereby changing the direction diagram of the WIFI antenna.

[0081] The L9 direction diagram coupling adjustment module is connected to the WIFI directional control module L6 and is set to adjust the direction based on the direction diagram coupling effect.

[0082] FIG. 8 is a schematic diagram of WIFI antenna direction diagram coupling modification according to an embodiment of the present disclosure. As shown in FIG. 8, the WIFI direction diagram modification method 3 described in this embodiment is a coupling adjustment method, specifically a direction diagram adjustment method for multi-MIMO antenna combination. When a terminal has N 2.4G or 5G antennas working together, and at the same time, when the terminal has multiple MIMO WIFI antennas, each antenna will generate a certain direction diagram and cover a certain range. Due to the coupling between the WIFI MIMO antennas, the correlation will change and the total transmission direction diagram will change. Here, by changing the power of different antennas and the optimal position of the direction diagram, a new total combined direction diagram can be formed.

[0083] That is, by selecting M antennas from N antennas to operate simultaneously, i.e., selecting the number of WIFI transmitting and receiving antennas, and controlling the signal strength and direction of each, a specific system direction diagram is generated through a predetermined antenna selection algorithm.

[0084] WIFI MIMO antenna combination 1: RSSI1,BLER1; WIFI MIMO antenna combination 2: RSSI2, BLER2; WIFI MIMO antenna combination 3: RSSI3, BLER3; WIFI MIMO antenna combination n: RSSIn, BLERn.

[0085] The direction diagram omnidirectional directional switching module L0 is connected to the WIFI directional control module L6 and is set to adjust the omnidirectional or directional mode according to the direction diagram. It is set to switch between two modes, omnidirectional and directional, of the WIFI antenna on the terminal. The omnidirectional directional switching module described in this disclosure performs self-adaptive switching control by detecting the current connection scene and signal strength, specifically as follows:

[0086] When the AP location to which the terminal is connected is unknown or the terminal is in the initial connection, the terminal WIFI is in the omnidirectional radiation mode. By default, the terminal WIFI is in the omnidirectional radiation operation mode.

[0087] Omnidirectional radiation mode has several scenarios, such as:

[0088] When the device WIFI and router are initially connected.

[0089] If your device cannot currently locate the router.

[0090] If the device itself is a Wi-Fi hotspot.

[0091] In normal mode, it is in omnidirectional radiation operation.

[0092] However, if the device already recognizes the location of the AP it is currently trying to connect to and the strength is weak and needs reinforcement, it can switch to directional radiation mode. Directional Diagram The directional radiation mode scenario is as follows:

[0093] When the AP router to be connected is known or its location is relatively fixed.

[0094] When the terminal is located at the coverage edge of the AP router.

[0095] If your device WIFI shows that the current signal strength is weak.

[0096] If your device's WIFI shows that the current upload and download speeds are low.

[0097] When some of the above scenarios or parameter thresholds occur, the WIFI antenna of this device can switch to directional radiation operation mode. This is achieved by increasing the switching on the WIFI antenna of the terminal. The directional diagram radiation position can be omnidirectional radiation, bilateral radiation, unilateral radiation, left and right side directional radiation, top and bottom side directional radiation, front and back side directional radiation, or directional radiation in a specific direction.

[0098] The SPNT single-pole multi-throw tuning switch changes the resonance characteristics of the WIFI signal feed point and signal feed point, and also changes the corresponding directional diagram. If the switch supports four states of antenna parasitics, it can support switching of up to four directional diagrams. If the switch supports eight states of antenna parasitics, it can support switching of up to eight directional diagrams. Slot directional diagram changing method: Multiple feed points are provided on the slot antenna of the antenna frame, and the directional diagram of the WIFI antenna can be changed by adjusting the positions of the different feed points.

[0099] In actual operation, the direction diagram dynamic tracking module L11 determines the communication WIFI antenna and direction diagram during the communication process between the terminal WIFI and the router. That is, the direction diagram of each antenna WIFI module emits a basic model before shipment. When the environment changes, for example, when the terminal direction or position is changed or the holding posture is adjusted, it is necessary to perform real-time dynamic tracking adjustment of the direction diagram.

[0100] FIG. 9 is a schematic diagram of a terminal WIFI direction diagram dynamic tracking according to an embodiment of the present disclosure. As shown in FIG. 9, the dynamic WITI antenna switching module, the WIFI direction diagram switching can be directly based on throughput, can be based on signal strength, or can even be based on obstacle detection.

[0101] If the device's location and orientation change during use, the latitude and longitude, acceleration sensor, gyro, and angular velocity sensor values ​​of the device's GPS module will change. If these parameters are detected to change and the Wi-Fi signal is lower than the threshold, real-time tracking adjustment of the Wi-Fi direction diagram will be initiated. The antenna direction diagram finally determined by actual measurements and a simulation algorithm will be combined or recombined. If the environment changes, real-time fine-tuning will be performed based on each collected value of the antenna direction diagram until the optimal communication conditions are reached, for example, until the Wi-Fi upload and download throughput peaks. Alternatively, other antenna direction diagram combinations can be recalculated and selected.

[0102] When a human body approaches the antenna of a mobile phone or when the holding posture changes, it affects each antenna of the mobile phone, but the distance, approach angle, and departure angle are different, and the types and frequency bands of the different antennas are different, so the changes in the displayed direction diagram will also be different.By testing the direction diagram, the effects of each part of the human body on the antenna can be collected, and different gestures and angles can be recognized by setting preset changes in a user setting interface or automatically detecting them, thereby realizing the transmission of human body-guided recognition commands.

[0103] The human body effect causes the shape of the antenna's directional diagram to change, resulting in stronger gain in some directions and weaker gain in others. By detecting the directional diagram and characteristic parameter values ​​in the magnetic induction effect at different distances between the human body and the mobile phone antenna, different human body proximity antenna positions, proximity distances, or combinations thereof can be automatically derived or set, and then compared with the antenna pattern and parameter model built into and collected by the terminal to determine and recognize different human body manipulation and holding postures.

[0104] WIFI direction diagram database establishment module L12. FIG. 10 is a schematic diagram of a two-dimensional WIFI antenna direction diagram according to an embodiment of the present disclosure. As shown in FIG. 10, the establishment of the direction diagram database is achieved by abstracting the radiation direction of each WIFI antenna of the terminal into a corresponding physical model, and then, according to the simulation model and actual measurement data, targeting specific application scenarios and AP locations, through software control and hardware adjustment.

[0105] The establishment of the direction diagram database further selects the optimal direction diagram WIFI antenna and direction diagram radiation mode based on the connection data of the terminal WIFI and specific AP information, and forms a storage mode, that is, by direction testing, direction selection, direction adjustment, and connection count accumulation storage, a new direction diagram database is formed, a stable and fast direction diagram channel is established, and bad signal fading direction during the propagation process can be avoided.

[0106] FIG. 11 is a schematic diagram of establishing a WIFI antenna direction diagram database according to an embodiment of the present disclosure. As shown in FIG. 11, the direction diagram model database is established by using the terminal center as the center of the circle, establishing a total of 12 direction diagram directions, with one WIFI radiation sector every 30 degrees in the horizontal 360° area. At the same time, a total of 12 direction diagram directions are established, with one WIFI radiation sector every 30 degrees in the vertical 360° area. Six of these are in the upper hemisphere and six in the lower hemisphere. The requirements for the strongest WIFI scattering angle and gain magnitude in each direction must meet a predetermined threshold requirement.
