Referring to fig. 6, fig. 6 is a flowchart of another antenna selection method provided in an embodiment of the present invention, and is applied to a terminal having multiple antennas. As shown in fig. 6, the method comprises the following steps:
In step 601, system information and frequency band information of terminal communication may be determined. The mode of terminal communication may be GSM, WCDMA or FDD LTE, etc., each mode may include multiple frequency bands, and each frequency band may include a transmitting frequency band and a receiving frequency band.
In step 602, the terminal may be provided with a plurality of antennas. Assume that the terminal of the embodiment of the present invention has two antennas, antenna 1 and antenna 2.
The communication mode and frequency band of the terminal are assumed to be an FDD LTE B1 frequency band, and the transmitting frequency band is 1920MHz-1980 MHz; the receiving frequency band is 2110MHz-2170 MHz. The target quadrant where the impedance position of the radio frequency transceiver is located can be determined according to the prestored impedance position of the radio frequency transceiver in the frequency band of the above system. Taking transmission as an example, the target quadrant where the impedance position of the radio frequency transceiver is located may be determined according to the prestored impedance position of the radio frequency transceiver in the transmission frequency band of the B1 frequency band of the FDD LTE, and it is assumed that the target quadrant where the impedance position of the radio frequency transceiver is located is the second quadrant. Still taking fig. 2 as an example, in fig. 2, the small box located in the second quadrant is the impedance position of the radio frequency transceiver.
There are also a number of irregular patterns surrounding the small boxes in fig. 2. The output power of the radio frequency transceivers corresponding to all points on the same irregular figure is the same, and the output power of the radio frequency transceivers corresponding to different irregular figures is different. And the farther away from the irregular pattern of small boxes in fig. 2, the smaller the output power of the corresponding rf transceiver.
The output power of the radio frequency transceiver corresponding to the impedance position of the antenna can be determined according to the prestored impedance position of each antenna in the plurality of antennas in the frequency band of the above system.
Still taking fig. 3 as an example, in fig. 3, Mark1 is located at an impedance position of 1920MHz within the transmission frequency band of B1 frequency band of FDD LTE, of antenna 1; mark2 is located at an impedance position of 1980MHz within the transmission band of the B1 band of FDD LTE for antenna 1. As seen in fig. 2 and 3, the impedance position of the antenna 1 in the transmission band of the B1 band of the FDD LTE is approximately located on the third irregular pattern in fig. 2, which encloses the small box and is along the direction away from the small box.
Still taking fig. 4 as an example, in fig. 4, Mark1 is located at an impedance position of the antenna 2 at 1920MHz within the transmission frequency band of the B1 frequency band of FDD LTE; mark2 is located at the impedance position of antenna 2 at 1980MHz within the transmission band of the B1 band of FDD LTE. As seen in fig. 2 and 4, the impedance position of the antenna 2 in the transmission band of the B1 band of FDD LTE is approximately located on the sixth irregular pattern in fig. 2, which encloses the small box and is along the direction away from the small box. Because the third irregular figure is closer to the small square frame and the sixth irregular figure is farther from the small square frame, the output power of the radio frequency transceiver corresponding to the third irregular figure is greater than the output power of the radio frequency transceiver corresponding to the sixth irregular figure.
In step 603, the antenna whose output power of the corresponding radio frequency transceiver is the target power may be determined as the target antenna. The target power is the maximum output power in the output powers of the plurality of radio frequency transceivers corresponding to the plurality of antennas in the frequency band of the above system. And in the frequency band of the system, the target antenna is matched with a radio frequency transceiver of the terminal.
As shown in step 602, the impedance position of the antenna 1 in the transmission frequency band of the B1 frequency band of the FDD LTE is approximately located on the third irregular pattern which surrounds the small box and is along the direction away from the small box in fig. 2; the impedance position of the antenna 2 in the transmission band of the B1 band of FDD LTE is approximately located on the sixth irregular pattern in fig. 2, which encloses the small box and is in the direction away from the small box. And the output power of the radio frequency transceiver corresponding to the third irregular figure is greater than the output power of the radio frequency transceiver corresponding to the sixth irregular figure, that is, the output power of the radio frequency transceiver corresponding to the impedance position of the antenna 1 in the transmission frequency band of the B1 frequency band of the FDD LTE is greater than the output power of the radio frequency transceiver corresponding to the impedance position of the antenna 2 in the transmission frequency band of the B1 frequency band of the FDD LTE. Therefore, it can be determined that the antenna 1 is the target antenna.
Optionally, the determining that the antenna whose output power of the corresponding radio frequency transceiver is the target power is the target antenna includes:
determining a voltage standing wave ratio of each antenna in at least two antennas in the frequency band of the standard under the condition that the output powers of at least two radio frequency transceivers corresponding to the at least two antennas are the same and the output power of the radio frequency transceiver is the maximum output power in the output powers of a plurality of radio frequency transceivers corresponding to the plurality of antennas;
and determining the antenna with the minimum voltage standing wave ratio in the at least two antennas as the target antenna.
Further, under the condition that the output powers of at least two radio frequency transceivers corresponding to the at least two antennas are the same and the output power of the radio frequency transceiver is the maximum output power among the output powers of the plurality of radio frequency transceivers corresponding to the plurality of antennas, the voltage standing wave ratio of each antenna in the at least two antennas in the frequency band of the above standard can be determined. And then the antenna with the minimum voltage standing wave ratio in the at least two antennas can be determined as the target antenna.
For example, assuming that the impedance position of the antenna 1 in the transmission frequency band of the B1 frequency band of the FDD LTE and the impedance position of the antenna 2 in the transmission frequency band of the B1 frequency band of the FDD LTE are both located on the same irregular figure surrounding the small square in fig. 2, the output power of the radio frequency transceiver corresponding to the impedance position of the antenna 1 in the transmission frequency band of the B1 frequency band of the FDD LTE is equal to the output power of the radio frequency transceiver corresponding to the impedance position of the antenna 2 in the transmission frequency band of the B1 frequency band of the FDD LTE. At this time, the voltage standing wave ratio of the antenna 1 in the transmission frequency band of the B1 frequency band of the FDD LTE may be determined, for example, the voltage standing wave ratio of the antenna 1 at 1950MHz in the transmission frequency band of the B1 frequency band of the FDD LTE may be determined; the voltage standing wave ratio of the antenna 2 within the transmission frequency band of the B1 frequency band of the FDD LTE may also be determined, for example, the voltage standing wave ratio of the antenna 2 at 1950MHz within the transmission frequency band of the B1 frequency band of the FDD LTE may be determined.
Next, the vswr of the antenna 1 at 1950MHz within the transmission band of the B1 band of the FDD LTE may be compared with the vswr of the antenna 2 at 1950MHz within the transmission band of the B1 band of the FDD LTE. Then, the antenna with the smallest voltage standing wave ratio of the antennas 1 and 2 can be determined as the target antenna.
And step 604, performing communication in the frequency band of the system by using the target antenna.
In step 604, after the target antenna is determined, the target antenna may be used for communication in the frequency band of the above-mentioned system. For example, after determining that the antenna 1 is the target antenna, the antenna 1 may be used for communication in the transmission frequency band of the B1 frequency band of FDD LTE.
The antenna selection method of the embodiment of the invention is applied to a terminal with a plurality of antennas. Therefore, the system information and the frequency band information of the terminal communication can be determined, and the antenna matched with the radio frequency transceiver of the terminal in the system and the frequency band of the terminal communication can be further determined. The antenna can be used for communication in the frequency band of the above system. An independent antenna is used for transmitting signals, and an independent antenna is used for receiving signals. The antenna structures are separated, and the optimal radiation can be realized by transmitting signals or receiving signals. The matching degree of the antenna and the radio frequency transceiver is better.
Referring to fig. 7, fig. 7 is a flowchart of another antenna selection method provided in an embodiment of the present invention, and is applied to a terminal having multiple antennas. As shown in fig. 7, the method comprises the following steps:
In step 701, system information and frequency band information of terminal communication may be determined. The mode of terminal communication may be GSM, WCDMA or FDD LTE, etc., each mode may include multiple frequency bands, and each frequency band may include a transmitting frequency band and a receiving frequency band.
In step 702, a target antenna may be determined according to a pre-stored correspondence relationship between radio frequency transceivers and antennas in each frequency band of each system. And in the frequency band of the system, the target antenna is matched with a radio frequency transceiver of the terminal.
For example, the antennas matched with the radio frequency transceiver in each frequency band under GSM can be determined in advance; the antennas matched with the radio frequency transceiver in each frequency band under WCDMA can be determined in advance; the antennas matched with the radio frequency transceivers in each frequency band in the FDD LTE can be determined in advance. For example, the antenna matched with the radio frequency transceiver in the transmission frequency band of the B1 frequency band of FDD LTE is antenna 1; the antenna matched with the radio frequency transceiver in the reception band of the B1 band of FDD LTE is antenna 2, and so on. The determined corresponding relation between the radio frequency transceiver and the antenna in each frequency band of each system can be written into the terminal.
Assuming that the system and frequency band of the terminal communication are the receiving frequency band of the B1 frequency band of the FDD LTE, it can be known that the antenna matched with the radio frequency transceiver in the receiving frequency band of the B1 frequency band of the FDD LTE is the antenna 2 according to the pre-stored correspondence between the radio frequency transceiver and the antenna in each frequency band of each system. And the antenna 2 can be determined as the target antenna.
And 703, performing communication in the frequency band of the system by using the target antenna.
In step 703, after the target antenna is determined, the target antenna may be used to perform communication in the frequency band of the above-mentioned system.
