At present, the latest Wi-Fi 6 greatly improves throughput and the number of device connections through an OFDMA (Orthogonal Frequency Division Multiple Access ) + MU-MIMO (Multi-User Multi-Input Multi-Output) technology, and the highest rate can reach 9.6 Gbps. In practice, Wi-Fi is a relatively common internet communication method.
However, in the actual use process of the Wi-Fi function, the Wi-Fi function is a short-distance communication mode, the Wi-Fi function of the electronic device accesses the internet by means of a router, and in an actual situation, the router is fixed in position and is often installed in a specific position, and meanwhile, the coverage range of an antenna adopted by the router is often small.
In the design of the Wi-Fi circuit, due to the limitation of the appearance of the electronic equipment and other functional modules, the position of the Wi-Fi antenna is relatively fixed, the number of the Wi-Fi antennas is small, and the occupied area is small. The design of existing Wi-Fi circuit solutions has two limitations:
1. in an actual user scene, the Wi-Fi antenna is covered due to the hand holding mode of the user, and the performance of the Wi-Fi antenna is weakened.
2. Due to the limitation of the antenna structure, the directional diagram of the antenna is relatively fixed, so that the maximum signal main lobe of the antenna directional diagram of the Wi-Fi cannot be superposed with the direction main lobe of the router antenna in the moving process of a user, and the performance of the antenna is reduced.
Both of the above factors affect Wi-Fi throughput.

According to the embodiment of the invention, by adding the switch unit and the phase shifter in the antenna circuit, by means of the advantages of multiple antennas, and by adjusting the switch unit to switch on or off the signal path and adjusting the phase of the signal by adjusting the phase shifter, the directional diagram of the antenna can be changed by the short-distance communication signal radiated by the electronic equipment through a beam forming mechanism, so that the performance of the antenna is improved to the maximum extent, the attenuation of the short-distance communication signal in the processes of holding and moving is reduced, and the throughput of short-distance communication is improved.
As shown in fig. 2, an embodiment of the present invention further provides an antenna performance adjusting method, which is applied to the electronic device described above, where the method includes:
In the embodiment of the invention, the antenna performance is improved by adjusting the phase of the short-distance communication signal and the antenna interface which is conducted by the signal transceiving unit.
As an alternative embodiment, step 202 comprises:
under the condition that the throughput of the antenna radiation unit is smaller than a first preset value and/or the RSSI is smaller than a second preset value, acquiring combined data of the state of the switch unit and the phase adjustment value of the phase shifter, which are pre-stored in a register;
modifying the state of the switch unit and the phase adjustment value of the phase shifter to combined data in the register in sequence, and detecting the throughput and/or the RSSI of the antenna radiation unit after each modification;
and if the currently detected target throughput is greater than a first preset value and/or the target RSSI is greater than a second preset value, determining to use the combined data corresponding to the target throughput and/or the target RSSI.
In other words, when the electronic device is in operation, the RSSI and the throughput of the antenna radiation unit corresponding to the short-distance communication are monitored in real time, and when the RSSI and/or the throughput are deteriorated, the CPU first traverses the state of the known switch unit and the phase adjustment value of the phase shifter in the call register, and determines whether the throughput and the RSSI are improved. If there is an improvement, the current state of the switching element and the phase adjustment value of the phase shifter are used.
Wherein the state of the switching unit includes: and connecting or disconnecting any signal transceiving unit with any antenna interface.
Optionally, the method further comprises:
traversing and scanning the electronic equipment in different states, and selecting the optimal throughput and/or the optimal RSSI received by the antenna;
the state of the switching unit and the phase adjustment value of the phase shifter corresponding to the optimal throughput and/or the optimal RSSI are formed as combined data to exist in the register.
For example, the switch unit and the phase shifter in the antenna circuit described above are set by default according to OTA (over the air performance) performance when the electronic device is shipped from the factory. The default setting refers to that under the condition of different hands, the electronic equipment is moved to be positioned at different directions of the router, traversal scanning is carried out, and the optimal combined data of the switch unit and the phase shifter is selected and stored in a CPU register.
In the above example, after traversing the combined data in the register, the throughput and RSSI are not improved; that is, if the throughputs detected after traversing the combined data in the register are both smaller than a first preset value and/or the RSSI is both smaller than a second preset value, the method further includes:
adjusting the state of a switch unit and a phase adjustment value of a phase shifter according to a preset rule, and detecting the throughput and/or the RSSI of the antenna radiation unit after each adjustment;
and if the currently detected throughput is greater than a first preset value and/or the RSSI is greater than a second preset value, determining the state of the switch unit and the phase adjustment value of the phase shifter obtained by using the current adjustment.
Under the condition, the electronic equipment starts to perform traversal scanning on the switch unit and the phase shifter to obtain a group of combined data of the switch unit and the phase shifter with optimal throughput and RSSI (received signal strength indicator) in the current state, so that the desired throughput of antenna radiation is improved to the maximum extent, and the user experience is improved.
In summary, the embodiments of the present invention provide a method for adding a phase shifter and a switch unit, calling known parameters in use, and dynamically adjusting the switch unit and the phase shifter in real time, thereby improving the limitation of the throughput of the antenna in short-distance communication to factory performance. By calling the known parameters, the function speed is high, a proper state can be found quickly, and the user experience is improved; further, the optimal antenna performance under the current use scene can be found by utilizing hardware to the maximum extent through real-time state adjustment under the condition that the known parameters can not improve the antenna performance, the antenna throughput is improved, and the user experience is improved.
