Description

Technical Field

[0001] This application relates to the field of communications, and more specifically, to a terminal antenna adjustment method, apparatus, storage medium, and electronic device. Background Technology

[0002] The coordinate energy distribution map of the electromagnetic radiation field of a Wi-Fi antenna in omnidirectional space is called the radiation pattern. This is further divided into TRP and TIS radiation patterns. A radiation pattern expressed in terms of radiation field intensity is called a field strength radiation pattern, and one expressed in terms of power density is called a power radiation pattern. The Wi-Fi radiation pattern can represent the antenna gain distribution in various directions. The direction of Wi-Fi radiation determines which direction Wi-Fi faces for optimal performance, maximum coverage, and a stronger signal. The higher the protocol type (e.g., 802.11b / g / a / n / ac / ax) the router assigns to the terminal, the higher the allocated MCS rate, and the higher the final Wi-Fi transmission throughput. In related technologies, the operating channel and frequency band of Wi-Fi are often relatively fixed and cannot be dynamically switched or adjusted, nor can the poor directivity be compensated for.

[0003] There is currently no solution to the problem that the working channels and frequency bands of WIFI in related technologies are often relatively fixed and cannot be dynamically switched or adjusted, nor can the problem of poor directionality be compensated. Summary of the Invention

[0035] This embodiment provides a method for adjusting the terminal antenna of the aforementioned computer device. Figure 2 This is a flowchart of a terminal antenna adjustment method according to an embodiment of this application, such as... Figure 2 As shown, the process includes the following steps:

[0036] Step S202: Collect the signal quality status of the terminal antenna in each channel path;

[0037] Step S204: Detect obstacles in the transmission direction of the terminal antenna;

[0039] Step S208: Adjust the terminal antenna radiation based on at least one of the signal quality status, obstacles, and the relative position information.

[0040] Through the above steps S202 to S208, the problem that the working channel and frequency band of WIFI in related technologies are often relatively fixed and cannot be dynamically switched and adjusted, and the problem that poor directionality cannot be compensated can be solved. The WIFI antenna can adaptively adjust the radiation direction and connect with the connected router with the best radiation antenna and path, thereby enhancing the WIFI signal strength and improving the user's WIFI experience.

[0041] In this embodiment of the application, step S208 may specifically include:

[0042] S2081, determine the working antenna of the terminal antenna based on at least one of the signal quality status, obstacles and the relative position information, wherein the working antenna is a single antenna or a combination of antennas;

[0044] S2082 adjusts the terminal antenna using the working antenna to ensure that the signal quality of the terminal antenna meets preset conditions.

[0045] Furthermore, S2082 may specifically include:

[0046] Switch the control terminal antenna to the working antenna;

[0047] If the signal quality of the terminal antenna meets the above preset conditions after switching to the working antenna, the adjustment of the terminal antenna is completed.

[0048] If the signal quality of the terminal antenna does not meet the above preset conditions after switching to the working antenna, the radiation direction of the working antenna pattern is adjusted according to the parasitic effect and / or coupling effect of the working antenna pattern.

[0049] If the signal quality of the terminal antenna meets the above preset conditions after the radiation direction of the working antenna is adjusted, the adjustment of the terminal antenna is completed.

[0050] If the signal quality of the terminal antenna does not meet the preset condition after the radiation direction of the working antenna is adjusted, the radiation mode of the working antenna is switched, and the adjustment of the terminal antenna ends. The radiation mode includes omnidirectional radiation mode and directional radiation mode.

[0051] In one embodiment, adjusting the radiation direction of the working antenna based on the parasitic effect of the antenna's radiation pattern may specifically include at least one of the following: adding a tuning switch or a slot length variable control unit to each antenna to change the radiation pattern corresponding to the working antenna; adjusting the radiation pattern on the ground feed by using a variable device that changes the radiation pattern; or adjusting the radiation direction of the radiation pattern by switching on and off the RC inductor tuning device and changing the RC inductance value on the main signal feed path.

[0052] In one embodiment, the above-mentioned adjustment of the radiation direction of the working antenna based on the coupling effect of the working antenna's radiation pattern may specifically include: forming a new radiation pattern of the working antenna by changing at least one of the working antenna's power, signal strength, and azimuth of the radiation pattern.

[0053] In another embodiment, the above-mentioned switching of the radiation mode of the working antenna may specifically include: controlling the radiation mode to omnidirectional radiation mode when the location of the router to which the terminal is connected is unknown or when the connection is initial; and / or controlling the radiation mode to switch to directional radiation mode when the terminal has identified the location of the router to be connected and the signal strength of the router is less than a third preset threshold.

[0054] In an optional embodiment, the method further includes: selecting the optimal radiation pattern and radiation mode of the terminal antenna based on the connection data between the terminal antenna and the preset router; and / or adjusting the radiation pattern of the terminal antenna by performing at least one of multiple direction tests, direction selections, and direction adjustments to form an omnidirectional radiation pattern of the terminal antenna; and storing the omnidirectional radiation pattern in a radiation pattern library.

[0055] In this embodiment of the application, step S202 may specifically include: real-time acquisition of the signal quality status of the terminal antenna in each channel path through the baseband chip and the antenna chip connected to the baseband chip, wherein the signal quality status includes at least one of the following: uplink and downlink throughput, RSSI value, bit error rate, and SNR signal-to-noise ratio.

[0056] In this embodiment of the application, step S206 may specifically include: collecting the terminal's location information at a preset time period, determining the distance difference between the location information collected in the current time period and the location information collected in the previous time period, and if the distance difference is greater than a preset distance, determining that the terminal antenna has changed position relative to the router, generating and acquiring location change information, where the relative position information includes location change information; or acquiring the terminal's current position and the initial position when the terminal is connected to the router, determining the distance and direction between the current position and the initial position; based on the omnidirectional radiation pattern of the terminal antenna, determining and acquiring the relative position and relative direction between the terminal antenna and the router according to the distance and direction, where the relative position information includes the relative position and relative direction.

[0057] In this embodiment of the application, step S204 may specifically include:

[0058] S2041, obstacles in the transmission direction of the terminal antenna are detected by near-ground obstacle detection;

[0059] Furthermore, step S2041 may specifically include: detecting whether there is an interfering or obstructing signal source within a preset distance range for the terminal antenna; if an interfering or obstructing signal source exists, determining that there is an obstacle in the transmission direction of the terminal antenna; if no interfering or obstructing signal source exists, determining that there is no obstacle in the transmission direction of the terminal antenna; transmitting a charge signal to the router, which is radiated through the corresponding terminal antenna and returns upon encountering an obstacle; if the returned charge signal from the router is detected, determining that there is an obstacle in the transmission direction of the terminal antenna; if no returned charge signal from the router is detected, determining that there is no obstacle in the transmission direction of the terminal antenna.

[0060] S2042 detects obstacles in the transmission direction of the terminal antenna by means of remote obstacle detection.

[0061] Furthermore, step S2042 may specifically include: determining the time difference between the signal transmitted to the router and the signal returned by the router; based on the difference between this time difference and the theoretical time difference in a predetermined unobstructed state, if the difference is greater than or equal to a first preset threshold, determining that there is an obstacle in the transmission direction of the terminal antenna; if the difference is less than the first preset threshold, determining that there is no obstacle in the transmission direction of the terminal antenna; determining the attenuation difference between the signal strength of the signal transmitted by the router and the theoretical signal strength in a predetermined unobstructed state; if the attenuation difference is greater than or equal to a second preset threshold, determining that there is an obstacle in the transmission direction of the terminal antenna; if the attenuation difference is less than the second preset threshold, determining that there is no obstacle in the transmission direction of the terminal antenna.

[0062] In this embodiment, the radiation pattern refers to the coordinate energy distribution map of the electromagnetic wave radiation field of the terminal antenna in omnidirectional space. The radiation patterns of the terminal antenna in each direction are called omnidirectional radiation patterns.

[0063] The aforementioned terminal antenna can be a WIFI antenna or other antennas. The following describes the embodiments of this application in detail using a WIFI antenna as an example.

[0064] This embodiment primarily addresses the directionality issue of terminal Wi-Fi. Based on the terminal's position relative to the router and the surrounding environment, the direction and pattern of the terminal's Wi-Fi antenna are changed in real time. Specifically, this includes: monitoring the terminal's Wi-Fi throughput and error rate to determine if the current Wi-Fi quality problem is caused by directionality; establishing a terminal Wi-Fi pattern model and calling the configuration in real time; testing the relative position and direction of the terminal's Wi-Fi and the router, and adjusting the antenna direction to improve throughput; detecting user-held devices and near / far obstacles, employing directional anti-interference detection technology to address near-ground and far-ground interference and obstacles, detecting and avoiding influencing objects; reconstructing the pattern of the multi-MIMO Wi-Fi antenna on the terminal to ensure the terminal's Wi-Fi maximum gain radiation direction is towards the router; changing the Wi-Fi antenna's radiation pattern through an antenna pattern coupling algorithm; adjusting the pattern at different directional positions through a parasitic pattern adjustment algorithm; and addressing the issue of a small scanning angle in the current pattern through an omnidirectional pattern adjustment algorithm. Finally, switching the two Wi-Fi front-end modules to N directions reduces blind spots and improves the terminal's real-time dynamic throughput performance. The relative position and orientation of the terminal and router are tracked in real time and adaptively adjusted dynamically to ensure alignment.

[0065] Figure 3 This is a system architecture diagram of a 5G terminal device with dynamic directional adaptation of WIFI according to an embodiment of this application, such as... Figure 3 As shown, the mobile terminal includes a WIFI antenna status acquisition module L1, a directional mapping module L2, a directional scanning and selection module L3, a near-far ground interference detection module L4, a WIFI directional control module L5, a multi-WIFI antenna extension module L6, a pattern selection adjustment module L7, a pattern parasitic adjustment module L8, a pattern coupling adjustment module L9, a pattern omnidirectional switching module L10, a pattern dynamic tracking module L11, and a pattern library establishment module L12.

[0066] Figure 4 This is a schematic diagram of WIFI antenna status acquisition according to an embodiment of this application, as shown below. Figure 4As shown, the WIFI antenna status acquisition module L1 is connected to the WIFI direction scanning and selection module L3, and is used to acquire the status and signal quality of each MIMO antenna in the terminal's WIFI 2.4G / 5G / 6G networks. This includes signal strength in each WIFI channel path, such as RSSI value, or performance parameters of each channel, such as throughput, bit error rate, and SNR. The antenna status and signal quality status acquisition values ​​are collected in real time by the mobile phone baseband chip and its connected WIFI chip, capturing and reporting each value. This antenna status includes the aforementioned parameter values ​​for the antenna status of multiple MIMO paths CH0 / CH1 / CHn.

[0067] Figure 5 This is a schematic diagram of WIFI antenna pattern testing and azimuth mapping according to an embodiment of this application, as shown below. Figure 5 As shown, the directional mapping module L2 is connected to the directional scanning and selection module L3 and is used for directional testing of the terminal's WIFI antenna. The WIFI antenna path sequence forms a mapping table for easy access.

[0068] The radiation patterns of each antenna on the tested terminal are measured and saved to a Wi-Fi radiation pattern library. The steps for testing and selecting the mapping are as follows:

[0069] The radiation pattern of the WIFI antenna is obtained through OTA testing in an anechoic chamber before leaving the factory. The control module controls the terminal to switch between a certain WIFI antenna and antenna path, forming multiple signal and antenna paths S1, S2,...Sn. Each path tests a complete omnidirectional 360-degree radiation pattern F1, F2...Fn.

[0070] In each directional pattern, values ​​and directions exceeding certain thresholds, such as ERP and EIS values ​​meeting certain intensity requirements, will be selected and processed.

[0071] The ERP and EIS, azimuth values, and WIFI antenna path sequences are mapped into a table for easy access.

[0072] The WIFI direction scanning and selection module L3, connected to the WIFI directionality control module L5, is used for testing and selecting the strongest directionality of the terminal's WIFI antenna and the connected router. While the location of the WIFI router connected to the terminal is relatively fixed, the terminal's WIFI location frequently changes as the user moves and the way the user holds the terminal changes. This means the directionality differs at different points of use, and even at the same location, the directional pattern differs depending on the orientation. Even at the same location and orientation, the directional pattern can vary depending on the near and far objects and obstacles.

[0073] Due to the inherent limitations of Wi-Fi antennas, both AP and station terminal antennas possess a certain degree of directionality. The characteristics of Wi-Fi directionality are as follows: the radiation pattern of a Wi-Fi antenna is omnidirectional, not a regular spherical shape; that is, the signal is strong in some directions and weak in others, as shown in the diagram below. If the antenna patterns of the terminal's Wi-Fi antenna and the router's antenna are opposite, the Wi-Fi signal is weak; if the antenna patterns of the terminal's Wi-Fi antenna and the router's antenna are aligned and orthogonal, the Wi-Fi signal is strongest.

[0074] The purpose of the WIFI orientation scanning and selection module L3 is to measure the orientation of terminals and routers. Figure 6 This is a schematic diagram of WIFI antenna directional scanning and selection according to an embodiment of this application, such as... Figure 6 As shown, two measurement methods are used here:

[0075] The scanning test method uses software to control the Wi-Fi antennas to operate in different positions, achieving omnidirectional scanning of the radiation pattern in every direction and angle. Distributed antennas on the terminal divide the Wi-Fi antennas into different areas and angles. Each antenna is switched sequentially, transmitting a Wi-Fi signal to the target router. By analyzing the received signal strength, the radiation pattern of the target router's and the terminal's Wi-Fi antennas is determined to be closest, thus obtaining an initial rough direction. Then, by adjusting the antenna combination strategy, the bias of the radiation pattern is changed, ultimately measuring the optimal position of the specific radiation pattern.

[0076] Relative positioning test method: When the WIFI terminal first connects to the router, the terminal is close to the AP, and the mobile terminal records the location information A of the AP, such as latitude and longitude. When the mobile phone moves to location B, the terminal records the latitude and longitude information of location B. The positioning test module measures the distance and direction between points A and B. If the orientation does not match the maximum radiation direction of the WIFI terminal, the control module is switched to switch the current direction of the direction map so that the strongest signal direction is always maintained.

[0077] The near-ground and far-ground interference detection module L4 is connected to the WIFI directionality control module L6 and the direction scanning and selection module L3, and is used for obstacle detection in the maximum transmission direction of WIFI. It operates in two modes: near-ground detection and far-ground detection. If an obstacle is detected in a certain direction, the radiation direction needs to be switched to change.

[0078] The near-ground obstacle detection method based on directional patterns detects whether there are interference or signal obstruction sources within a certain distance range (e.g., 0.3 meters, 0.5 meters, 1 meter) around the terminal's Wi-Fi antenna. These sources could include a user's hand, a metal object, or the user's body obstructing the signal. This method detects SAR signals in multiple directions on the terminal. When a user's hand or other object is detected approaching, a change in the SAR signal is triggered, allowing the module to determine the presence of an obstacle in that direction.

[0079] This is achieved by connecting the ground or feed point of each WIFI antenna on the terminal to each channel of the SAR chip. The SAR chip adopts a multi-channel design, such as one-to-three or one-to-four. If there are currently four WIFI antennas, one 1-to-4 SAR chip is sufficient. If the terminal currently has eight primary and backup antennas, two 1-to-4 SAR chips are used.

[0080] When the WIFI is working, a charge signal is emitted from the SAR chip. This charge signal is radiated through the corresponding WIFI metal or FPC antenna. Upon encountering an obstacle, it is reflected back and received by the corresponding WIFI antenna. The signal is then transmitted back to the SAR chip for detection and statistics via the on-board connections. This achieves obstacle detection in the direction of the corresponding WIFI antenna.

[0081] Directional pattern obstacle detection method: During WIFI communication, multiple antennas are used for data transmission, and one antenna is used for obstacle detection in a specific direction. Here, two detection methods are used.

[0082] The first method is the time difference calculation method. The distance AB between the WIFI terminal and the connected router AP is known. The time difference t1 between the transmitted signal and the returned signal from the router is calculated and compared with the theoretical time difference t2 when there are no obstacles. If there are obstacles in that direction, then t2>t1. The thicker and more numerous the obstacles, the larger the difference t1-t2=Δt will be.

[0083] The second method is the attenuation difference calculation method. Figure 7 This is a schematic diagram of a WIFI antenna scanning for near and far ground obstacles according to an embodiment of this application, as shown below. Figure 7 As shown, the attenuation value of the WIFI signal on the terminal varies depending on the material during medium- to long-distance transmission; the higher the frequency, the greater the attenuation. It is also divided into free space loss and physical material loss, with physical material loss further categorized into human body loss, wall loss, wood material loss, metal material loss, and glass material loss.

[0084] Meanwhile, this module also includes terminal WIFI electromagnetic interference detection. During operation, WIFI needs to stay away from other electromagnetic wave signals of the same frequency, near frequency, or with harmonics and intermodulation relationships. These signals originate from Bluetooth devices, microwave ovens, computers, televisions, high-voltage lines, mobile phones, tablets, and other WIFI and router electronic devices. Therefore, the terminal WIFI radiation pattern avoidance mechanism in this design also needs to avoid these interfering obstacles to prevent WIFI signal interference.

[0085] The L5 WIFI directional control module is connected to the directional pattern library module L12, the near-far ground interference scanning module L4, and the directional adjustment control modules L7-L11. It controls the WIFI antenna to operate in different positions via software, achieving omnidirectional directional pattern scanning. The directional control module controls the operation of the following components:

[0086] The number of active Wi-Fi antennas is controlled based on uplink and downlink throughput and other signal quality parameters.

[0087] Based on uplink and downlink throughput and other signal quality parameters, select the optimal radiation pattern direction to control one or more WIFI antennas.

[0088] The control mode based on antenna pattern switching: Based on uplink and downlink throughput and other signal quality parameters, the order of primary and secondary antennas in the MIMO antenna combinations (ch0, ch1, ch3...chn) is controlled. For example, if a mobile phone has multiple Wi-Fi antennas, how they are combined, which are the primary antennas and which are the secondary antennas, can be switched and changed. In other words, by switching channels between Wi-Fi front-end modules, the order of different primary and secondary Wi-Fi antennas and MIMO antennas is switched, thereby reconstructing the antenna pattern.

[0089] Control mode based on directional graph reconstruction: Based on the current application, business requirements, and throughput needs, implement business-based directional graph reconstruction. Terminal Wi-Fi throughput is divided into uplink upload throughput, downlink download throughput, and bidirectional transmission throughput. Based on current business requirements, perform uplink and downlink directional graph reconstruction.

[0090] Based on the WIFI directionality fine-tuning mode: After the WIFI antenna, WIFI path, and WIFI pattern are selected, if the current signal is not yet strongest, or there are obstacles in the transmission path, the pattern fine-tuning mode can be selected, which allows for precise and minor adjustments to the WIFI antenna pattern. The WIFI antenna pattern adjustment control sequence is shown in Table 1.

[0092]

[0093]

[0094] The multi-WIFI antenna extension module L6, connected to the directivity mapping module L2, is used for extending the WIFI MIMO antenna. WIFI antenna extension is implemented in two ways.

[0095] The first approach involves expanding the number of antennas, with the terminal having 2-N Wi-Fi antennas. By combining the orientation of each Wi-Fi antenna with the radiation pattern of the antennas, and through the antenna distribution layout in different directions, the Wi-Fi signal can be transmitted omnidirectionally without dead zones.

[0096] There are N antennas distributed around the top, bottom, left, and right sides of the phone, each corresponding to a specific direction where the antenna is strongest. Some antennas are independent channel antennas, while others are reused with antennas of other frequency bands and standards, such as a Wi-Fi antenna being parasitic on an LTE / NR antenna.

[0097] The second method is to expand the antenna position. For example, if a WIFI device has four antennas, each corresponding to a WIFI frequency band and channel, the traditional solution is relatively independent. Here, different WIFI antennas are interconnected through DPDT, 3P3T, 4P4T, and nPnT to form different switching and interconnection links, thereby expanding the antenna path.

[0098] The third type is the expansion of the front-end FEM. For example, a WIFI device contains four MIMO channels: CH0, CH1, CH2, and CH3. Each channel originally corresponds to a PA / LNA front-end module. Of course, it can also contain only one of the PA / LNA, or a front-end module that only contains filters and switches without PA / LNA. The WIFI antenna is connected to the WIFI chip through these front-end FEM modules. The traditional solution is one-to-one. Here, multiple-input multiple-output switches, such as DPDT, 3P3T, and 4P4T, are used to connect the inputs of these modules to the TX / RX output ports of the WIFI chip to form an interconnected state. Each FEM corresponds to one antenna, which can realize the interconnection and switching of antennas in different directions.

[0099] The pattern selection adjustment module L7, connected to the WIFI directivity control module L6, is used for adaptive adjustment of the WIFI antenna pattern on the terminal, ensuring that the WIFI signal on the terminal and the router are aligned with the direction of maximum radiation. Specifically, it selects the optimal single or combination of antennas from multiple MIMO (Multiple-Input Multiple-Output) WIFI antennas for maximum pattern adaptation and switching. Pattern adjustment can modify the pattern of a single antenna by changing the antenna structure matching, resonance, or parasitic effects, thereby altering the apparent current distribution of the individual WIFI antenna and thus changing the radiation direction. Pattern adjustment can also change the system pattern corresponding to multiple MIMO antennas.

[0100] The pattern parasitic adjustment module L8 is connected to the WIFI directivity control module L6 and is used for directional radiation adjustment based on the pattern parasitic effect.

[0101] The method for adjusting the radiation pattern of each Wi-Fi antenna involves adding a tuning switch or a variable-length slot control unit to each antenna to change the radiation pattern of the corresponding Wi-Fi antenna. This allows for the control and adjustment of the maximum gain radiation pattern in three-dimensional space, changing the strongest gain radiation direction of a single Wi-Fi antenna. There are two operating modes: the first changes the radiation pattern while the center frequency remains unchanged; the second changes both the radiation pattern and the center frequency, which is the radiation pattern adjustment method using a slot antenna or FPC antenna with variable electrical length on the terminal.

[0102] Method 2 for changing the Wi-Fi pattern: Parasitic regulation method

[0103] Along the Wi-Fi antenna path of the terminal, a radiation pattern is added to alter the structure. The metal frame of the terminal is divided into different sections and segments through gaps. Each section corresponds to an antenna direction, as shown in the diagram below: the lower left segment corresponds to the lower left direction, and the upper right segment corresponds to the upper right direction.

[0104] The variable device that changes the radiation pattern can be an SP4T tuning switch or a MEMS tuning switch to adjust the radiation pattern on the ground feed; or it can be an RC inductor tuning device on the main signal feed path, which can adjust the radiation direction of the maximum gain direction by switching on and off and changing the RC inductance value through different architectures.

[0105] Taking the metal-framed Wi-Fi antenna in the image below as an example, when the terminal's Wi-Fi needs to change its radiation pattern, it is only necessary to change the antenna gap between the on and off states. Different on and off states will change the surface current density of the Wi-Fi antenna and change the direction of the surface current, thereby changing the radiation pattern of the Wi-Fi antenna.

[0106] The L9 pattern coupling adjustment module is connected to the WIFI directivity control module L6 and is used for directional adjustment based on the pattern coupling effect.

[0107] Figure 8 This is a schematic diagram illustrating the change in the WIFI antenna pattern coupling according to an embodiment of this application, such as... Figure 8As shown, the third method for changing the WIFI radiation pattern in this embodiment is a coupling adjustment method, specifically a multi-MIMO antenna combination radiation pattern adjustment method. When the terminal has N 2.4G or 5G antennas working together, and simultaneously, when the terminal has multiple MIMO WIFI antennas, each antenna generates a certain radiation pattern, covering a certain range. Due to the coupling and correlation changes between the WIFI MIMO antennas, the overall transmission radiation pattern is changing. Here, by changing the power of different antennas and the optimal position of the radiation pattern, a new overall combined radiation pattern can be formed. That is, by selecting M antennas from N antennas to work together, i.e., selecting the number of WIFI transceiver antennas, and controlling their respective signal strength and direction, a specific system radiation pattern is generated through a predetermined antenna selection algorithm.

[0112] The omnidirectional switching module L10 is connected to the WIFI directionality control module L6 and is used to adjust the omnidirectional or directional mode based on the radiation pattern.

[0113] This invention relates to a module for switching between omnidirectional and directional modes of a Wi-Fi antenna on a terminal. The omnidirectional / directional switching module detects the current connection scenario and signal strength to perform adaptive switching control, as detailed below:

[0114] When the location of the access point (AP) connected to by the terminal is unknown, or during the initial connection, the terminal's Wi-Fi is in omnidirectional radiation mode. By default, this terminal's Wi-Fi operates in omnidirectional radiation mode.

[0115] The omnidirectional radiation mode has the following scenarios:

[0116] When the terminal's Wi-Fi and router are initially connected.

[0117] When the terminal cannot identify the current router location.

[0118] When the terminal itself acts as a Wi-Fi hotspot.

[0119] In normal mode, it operates in an omnidirectional radiation mode.

[0120] When the terminal has identified the location of the AP it wants to connect to, and the signal strength is weak and needs to be strengthened, it can switch to directional radiation mode. The scenario for directional radiation mode is as follows:

[0121] The connected AP router is known or its location is relatively fixed.

[0122] The terminal is located at the edge of the AP router's coverage area.

[0123] The terminal's Wi-Fi signal strength is currently weak.

[0124] The terminal's Wi-Fi display shows that the current uplink and downlink speeds are low.

[0125] When the above scenarios or parameter thresholds occur, the WIFI antenna of this device can switch to directional radiation mode. This is achieved by adding a switch to the WIFI antenna on the terminal. The radiation pattern can be selected as omnidirectional radiation, bilateral radiation, unilateral radiation, left-right directional radiation, top-bottom directional radiation, front-back directional radiation, or directional radiation in a specific direction.

[0126] By using a SPNT single-pole multi-throw tuning switch, the Wi-Fi signal feed point and its resonant characteristics can be altered, thereby changing the corresponding radiation pattern. For example, if the switch supports four states of antenna parasitic behavior, it can support switching between up to four radiation patterns. If the switch supports eight states of antenna parasitic behavior, it can support switching between up to eight radiation patterns. Another method is the slotted antenna pattern modification: multiple feed points are set in the slotted antenna within the antenna frame. By adjusting the positions of these feed points, the radiation pattern of the Wi-Fi antenna can be changed.

[0127] In actual operation, during the communication between the terminal's WIFI and the router, the WIFI antenna and its radiation pattern are already determined. That is, the radiation pattern of each antenna WIFI module will radiate a basic model before leaving the factory. If the environment changes, such as changes in the terminal's direction or position, or adjustments to the grip, then the radiation pattern needs to be dynamically tracked and adjusted in real time.

[0128] Figure 9 This is a schematic diagram of dynamic tracking of the terminal WIFI directional pattern according to an embodiment of this application, such as... Figure 9 As shown, the dynamic WITI antenna switching module can switch the WIFI radiation pattern directly based on throughput, signal strength, or obstacle detection.

[0129] When the terminal's location and orientation change during user operation, the values ​​from the GPS module's latitude and longitude, accelerometer, gyroscope, and angular velocity sensor will change. When these parameter changes are detected, and the Wi-Fi signal strength falls below a threshold, real-time tracking and adjustment of the Wi-Fi pattern is initiated. The final antenna pattern is combined or recombined using a combination of measured data and simulation algorithms. If the environment changes, real-time fine-tuning can be performed based on the collected antenna pattern values, or other antenna pattern combinations can be recalculated and selected until the optimal communication state is achieved, such as the highest peak Wi-Fi upload and download throughput.

[0130] When a person approaches a phone's antenna, or when their grip changes, it affects all of the phone's antennas. However, due to differences in distance, approach and departure angles, and the antenna type and frequency band, the resulting changes in the radiation pattern also differ. By testing the radiation pattern, the influence of different parts of the human body on the antennas can be collected. Preset changes can be set in the user settings interface or automatically detected to recognize different gestures and angles, thus enabling the issuance of human body sensing and recognition commands.

[0131] Due to the influence of the human body effect, the shape of the antenna's radiation pattern will change, with gain increasing in some directions and decreasing in others. By detecting the radiation pattern and characteristic parameter values ​​of the magnetic induction effect at different distances between the human body and the mobile phone antenna, different human body approaching the antenna position, approach distance, or combinations thereof can be automatically sensed or set. Then, it is compared with the antenna pattern and parameter model collected by the terminal to determine and recognize different human body operations and grip postures.

[0132] WIFI directional map library creation module L12, Figure 10 The WIFI antenna direction according to the embodiments of this application Figure 2 A diagram of a Vitagram, such as Figure 10 As shown, the establishment of the radiation pattern library model involves abstracting the radiation direction of each WIFI antenna of the terminal into a corresponding physical model. Through simulation models and measured data, it is implemented through software control and hardware adjustment for specific application scenarios and AP locations.

[0133] The establishment of the directional pattern library can also select the optimal directional pattern WIFI antenna and directional pattern radiation mode based on the connection data of the terminal WIFI and specific AP information, forming a memory mode. That is, through directional testing, directional selection, directional adjustment, and cumulative storage of connection times, a new directional pattern library is formed to establish a stable and high-speed directional pattern channel and avoid poor signal fading directions during propagation.

[0134] Figure 11 This is a schematic diagram established based on the WIFI antenna pattern library according to the embodiments of this application, such as... Figure 11As shown, the method for establishing the directional pattern model library is as follows: Using the terminal center as the center, a 360° horizontal area is divided into 12 WIFI radiation sectors, spaced 30° apart. Simultaneously, a 360° vertical area is also divided into 12 directional pattern sectors, spaced 30° apart. Six sectors are located in the upper hemisphere and six in the lower hemisphere. The angle of strongest WIFI distribution and the gain magnitude in each direction must meet a predetermined threshold requirement.
