Detailed Description
The present invention is further illustrated by the following examples, which are not to be construed as limiting the invention thereto.
Referring to fig. 1, the present embodiment provides a method for controlling an antenna for mimo communication, which is used in an electronic device having at least two antennas, and the method is stored in firmware or software of the electronic device and executed by using an operating system of the electronic device itself. The electronic device may be a notebook computer, a laptop computer, a tablet computer, a personal computer, a smart television, a small base station, or a wireless router, but the invention is not limited thereto. The method comprises the following steps. First, in step S110, the electronic device performs wireless communication with a remote device by using a first antenna and a second antenna simultaneously, that is, performs Multiple Input Multiple Output (MIMO) transmission communication by using at least two antennas. The specification of the application of Multiple Input Multiple Output (MIMO) transmission communication is, for example, 802.11n or the existing fourth generation mobile communication specification, or the future fifth generation mobile communication specification. When applied to future fifth generation mobile communication specifications, the operating frequencies of the first antenna and the second antenna are either the 3.5GHz band or the 6GHz band of the fifth generation mobile communication specifications.
Then, step S120 is performed to establish a plurality of communication representations according to the plurality of first radiation states of the first antenna and the plurality of second radiation states of the second antenna. The present invention is based on the objective of improving the performance (increasing the data rate) of mimo communication methods, and uses an antenna having a plurality of dual radiation states, or an antenna controlling its operation state to implement a plurality of radiation patterns (each operation state has a different radiation pattern). For example, the first antenna ATA has a double number of radiation states RA1, RA2, RA3 … RAm, and the second antenna ATB has a double number of radiation states RB1, RB2, RB3 … RBn. When the electronic device is in operation, a radiation state of the first antenna ATA (for example, RA1) and a radiation state of the second antenna (for example, RB1) are selected to obtain a corresponding communication performance P11, and then the radiation states of the first antenna ATA and the second antenna ATB can be continuously changed and selectively combined, so that a double number of communication performances can be obtained, for example, communication performances P11, P12, P13 … P1n, P21, P22, P23 …, P2n …, and the like can be obtained, so as to obtain a communication performance Pmn, which is the result of multiplying the total m by n communication performances. The communication performance is typically presented at a data rate. Moreover, the manner of changing the radiation states of the first antenna and the second antenna will be further described in the following fig. 2.
Next, step S130 is performed to obtain absolute difference values by subtracting the absolute value of the Received Signal Strength Indication (RSSI) of the first antenna from the absolute value of the received signal strength indication of the second antenna for each communication performance. That is, each communication performance (P11 and Pmn) will have an absolute value difference. The effect of changing the radiation state of the respective antennas on the mimo data rate may not be easily expected no matter whether the communication environment is good or bad, but the mimo data transmission (including stability) is more facilitated when the difference of the received signal strength indications of the first antenna and the second antenna is smaller. Then, step S140 is performed, and the communication performance with the smallest absolute value difference is selected as the optimized mimo communication. When the communication performance with the minimum absolute value difference is selected, no matter whether the communication environment is good or bad, the first antenna and the second antenna are both selected to have the best or better radiation state at the same time, which is most beneficial to the transmission of multiple inputs and multiple outputs. Conversely, the greater the difference in the received signal strength indications of the first antenna and the second antenna, the more unstable transmission may be for mimo communications or the more variable the data rate is likely to fluctuate, which is detrimental for mimo transmissions. In step S140, the communication performance with the minimum absolute value difference is selected as the optimized mimo communication, considering the difference between the absolute values of the received signal strength indicators of two or more antennas in a communication architecture using at least two antennas at the same time, and by selecting the minimum difference, the instability or uncertainty parameters of the transmission process are avoided as much as possible, and the optimization scheme can be provided in a convenient manner (cost reduction and operation time reduction) without performing complicated data operation on the mimo matrix. In addition, if the transmission environment or the transmission distance is changed during the mimo transmission, steps S120, S130, and S140 may be dynamically continued, so that an attempt may be dynamically made to find a better communication performance suitable for the situation under the condition that the normal transmission state is not affected.
Referring to fig. 1 and 2, in the step (S120) of establishing the even number of communication representations according to the even number of first radiation states of the first antenna and the even number of second radiation states of the second antenna, steps S121 and S122 of fig. 2 may be further included, and steps S121 and S122 are parallel because the first antenna and the second antenna of the mimo communication are simultaneously operated to transmit data. In step S121, at least one first reflection unit or at least one first ground current control unit of the first antenna is controlled. In step S122, at least one second reflecting unit or at least one second ground current control unit of the second antenna is controlled.
In steps S121 and S122, the first reflection unit and the second reflection unit are controlled by the same control method, and the first ground current control unit and the second ground current control unit are controlled by the other control method. Referring to the antenna and the reflection unit structure of fig. 3, the first reflection unit is, for example, a half-wavelength reflector, the first antenna is, for example, a half-wavelength dipole antenna, and in the manner of controlling the first reflection unit of the first antenna, at least two or more first reflection units 11 of the first antenna 1 are preferable, for example, one first half-wavelength reflector 111 of fig. 3 is on the left side and the other first half-wavelength reflector 112 is on the right side, so as to generate even radiation states of the first antenna 1. The control mode of the embodiment of fig. 3 includes: for the first half-wavelength reflector 111 on the left side, the first half-wavelength reflector 111 is turned on by the first diode 111a, so that the first half-wavelength reflector 111 realizes a reflecting function. Alternatively, the first diode 111a is turned off, and the first extension circuit 111b extends the path of the first half-wavelength reflector 111 by the first capacitor 111c, so that the first half-wavelength reflector 111 does not generate the reflection function. For the first half-wavelength reflector 112 on the right side, the first half-wavelength reflector 112 is turned on by the first diode 112a, so that the first half-wavelength reflector 112 performs a reflecting function. Alternatively, the first diode 112a is turned off and the first extension circuit 112b extends the path of the first half-wavelength reflector 112 by the first capacitor 112c, so that the first half-wavelength reflector 112 does not generate the reflection function. Similar to the control method of the first antenna 1, referring to fig. 4, the method of controlling the second reflecting unit 21 of the second antenna 2 includes: turning on the second half-wavelength reflector 211 by the second diode 211a, or turning off the second diode 211a and extending the path of the second half-wavelength reflector 211 by the second extension loop 211b using the second capacitor 211 c; and turning on the second half-wavelength reflector 212 with the second diode 212a or turning off the second diode 212a and causing the second extension loop 212b to extend the path of the second half-wavelength reflector 212 using the second capacitor 212 c.
Referring to fig. 5, the first ground current controlling unit 211 and the second ground current controlling unit 221 are used to connect to the ground G, the first antenna 21 and the second antenna 22 are exemplified by an inverted-F planar antenna (PIFA), and in the way of controlling the first ground current controlling unit 211 of the first antenna 21, the first ground current controlling unit 211 of the first antenna 21 needs to have at least two or more components, such as one first ground current portion 211a and another first ground current portion 211b of fig. 5, to generate radiation states of the dual types of first antennas 21 by changing the ground current close to the first antenna 21. The control method of the embodiment of fig. 5 includes: for the first ground current part 211a, the first switch 212a is used to turn on the first ground current part 211a to the ground G, or the first switch 212a is not turned on and the first ground capacitor 213a is connected between the first ground current part 211a and the ground G, and in fig. 5, the first ground current part 211a not only uses the first ground capacitor 213a, but also uses the first ground capacitor 213b to connect to the ground G. In addition, for the first ground current portion 211b, the first switch 212b is used to conduct the first ground current portion 211b to the ground G, or the first switch 212b is not conducted and the first ground capacitor 213b is connected between the first ground current portion 211b and the ground G.
With continued reference to fig. 5, the second ground current control unit 221 needs to have at least two or more components, such as one second ground current portion 221a and another second ground current portion 221b of fig. 5, to generate even radiation states of the second antenna 22 by changing the ground current near the second antenna 22. Similar to the control method of the first ground current control unit 211, the control method of the second ground current control unit 221 includes: in fig. 5, the second ground current portion 221a not only uses the second ground capacitor 223a, but also uses the second ground capacitor 223b to connect to the ground G, by turning on the second switch 222a to connect the second ground current portion 221a to the ground G, or turning off the second switch 222a and connecting the second ground capacitor 223a between the second ground current portion 221a and the ground G. Furthermore, the second switch 222b is used to conduct the second ground current portion 221b to the ground G, or the second switch 222b is not conducted and the second ground capacitor 223b is connected between the second ground current portion 221b and the ground G. However, the structure of the second antenna 22 is not necessarily the same as that of the first antenna 21, and the second ground current control unit 221 is not necessarily the same as that of the first ground current control unit 211. The switches 212a, 212b, 222a, and 222b are implemented by, for example, diodes, but are not limited thereto.
