Embodiments of the present application will be described below with reference to the accompanying drawings.
Fig. 2 is a schematic structural diagram of an antenna module according to the present application. As shown in fig. 2, the antenna module provided in the present application includes: the antenna comprises a patch 10, a plurality of antenna units (P1-P8) and a control chip (not shown), wherein the antenna units are fixed on the patch 10, a radio frequency feed-in point F is arranged on the patch 10, a transmission channel is arranged between the radio frequency feed-in point and each antenna unit, the time delays of the transmission channels (P10-P80) are the same, the control chip is connected with the radio frequency feed-in point F, and the control chip is used for acquiring a target antenna unit of which the communication quality meets preset conditions by switching the transmission channel when the communication quality of the antenna unit corresponding to the currently-connected transmission channel cannot meet the preset conditions, and communicating by using the target antenna unit.
In some scenarios, the antenna module may include: in other scenarios, such as multiple-in multiple-out (MIMO) scenarios, the antenna module may include: a multi-blade multi-position switch. The switching principle of the present application is described below in two scenarios.
When the antenna module comprises the single-blade multi-position switch, the single-blade multi-position switch is arranged between the radio frequency feed-in point F and the plurality of transmission channels and used for connecting the radio frequency feed-in point F with any transmission channel in the plurality of transmission channels.
Optionally, the patch 10 may be designed into any shape, and any point on the patch 10 may be used as the rf feed point F, as long as the transmission channel delays between the rf feed point F and each antenna unit are the same. Without limitation, the patch 10 may be designed with a geometric centrosymmetric pattern, such as: a circle, square, equilateral hexagon or equilateral triangle, etc., as illustrated in fig. 2.
Optionally, the plurality of antenna units are fixed on the patch 10 by at least one of the following processes: a Flexible Printed Circuit (FPC), a Laser Direct Structuring (LDS), or metal stamping. The performance of the plurality of antenna elements may be the same.
The principle of switching the antenna elements by the control chip is described as follows:
the control chip periodically or regularly detects the communication quality of the antenna unit corresponding to the currently-switched-on transmission channel and judges whether the communication quality meets a preset condition, if so, the antenna unit corresponding to the currently-switched-on transmission channel is continuously used for communication, if not, the antenna unit corresponding to the currently-switched-on transmission channel is switched to a first transmission channel through a single-pole multi-position switch, the first transmission channel can be any one of the transmission channels except the currently-switched-on transmission channel, the communication quality of the antenna unit corresponding to the first transmission channel is detected in real time, and if the communication quality of the antenna unit corresponding to the first transmission channel meets the preset condition, the antenna unit corresponding to the first transmission channel is used as a target antenna unit. If the communication quality of the antenna unit corresponding to the first transmission channel does not meet the preset condition, the control chip can be switched to a second transmission channel through the single-pole multi-position switch, and the second transmission channel is any transmission channel except the currently connected transmission channel and the first transmission channel. And similarly, detecting the communication quality of the antenna unit corresponding to the second transmission channel in real time, and making the same judgment, and thus sequentially switching the plurality of transmission channels until finding the antenna unit with the communication quality meeting the requirement.
It should be noted that: under the scene that the mobile terminal is just started, one transmission channel can be randomly connected for communication.
Optionally, in the single-pole multi-position scenario, the communication quality may be a signal-to-noise ratio, or a sensitivity, or a channel quality, etc.
For example, the antenna module shown in fig. 2 includes 8 antenna elements, which are respectively illustrated by P1, P2, P3, P4, P5, P6, P7, and P8. The central point of the patch 10 is a radio frequency feed point F, and 8 antenna units are fixed on the patch 10 according to the position shown in fig. 2. The antenna module further comprises 8 transmission channels which are P10, P20, P30, P40, P50, P60, P70 and P80 in sequence. The time delays of P10, P20, P30, P40, P50, P60, P70 and P80 are the same. The single-pole multi-position switch is arranged between the radio frequency feed-in point F and the 8 transmission channels and is used for connecting any one of the radio frequency feed-in point F and the 8 transmission channels.
It should be noted that: in the case that the patch 10 is designed to be circular, the number of the antenna units may be more than 8 as illustrated in fig. 2, or less than 8 as illustrated in fig. 2, which is not limited in this application, but it should be noted that: the greater the number of antenna elements, the greater the likelihood of finding an antenna element for which the communication quality meets the requirements.
The switching process of the antenna unit is described below with reference to the design shown in fig. 2:
assuming that the current single-pole multi-position switch is placed on the P10, that is, the P10 is turned on, that is, the antenna unit currently used by the mobile terminal is P1, the control chip periodically or periodically detects the communication quality of the P1, and determines whether the communication quality of the P1 satisfies a preset condition, for example, whether the signal-to-noise ratio is greater than a preset threshold, if the communication quality of the P1 satisfies the preset condition, the communication is continued using the P1, if the communication quality of the P1 does not satisfy the preset condition, the single-pole multi-position switch is switched to the P20, and likewise, the communication quality of the P2 is periodically or periodically detected, and determines whether the communication quality of the P2 satisfies the preset condition, if so, the communication is performed using the P2, if the communication quality of the P2 does not satisfy the preset condition, the single-pole multi-position switch is switched to the P30, so that the communication quality of the P20 → P30 → P585 → P50 → P70 is sequentially switched to the P70 → P70, until the target antenna unit is found in the P8-P639, and the target antenna unit is used for communication, so that the influence of the movement of the mobile terminal on the communication between the mobile terminal and the network equipment is reduced. In addition, the time delay of each transmission channel is the same, namely the time delay from each antenna unit to the radio frequency feed-in point is the same, so that the stability of the time delay in the process of switching the antenna units is ensured, and the user experience is improved.
Alternatively, referring to fig. 3, the patch 10 may be designed to be square, and the antenna module may include 4 antenna elements, which are illustrated by P1, P2, P3, and P4, respectively. The central point of the patch 10 is a radio frequency feed point F, the 4 antenna units are fixed on the patch 10 according to the position shown in fig. 3, and the antenna module further includes 4 transmission channels, which are P10, P20, P30, and P40 in sequence. The time delays of P10, P20, P30 and P40 are the same. The single-pole multi-position switch is arranged between the radio frequency feed-in point F and the 4 transmission channels and is used for connecting any one transmission channel of the radio frequency feed-in point F and the 4 transmission channels.
It should be noted that: in the case that the patch 10 is designed to be square, the number of the antenna units may be more than 4 as illustrated in fig. 3, or less than 4 as illustrated in fig. 3, which is not limited in this application, but it should be noted that: the greater the number of antenna elements, the greater the likelihood of finding an antenna element for which the communication quality meets the requirements.
The switching process of the antenna element is explained below with reference to the design shown in fig. 3:
assuming that the current single-pole multi-position switch is placed on P20, i.e. P20 is turned on, i.e. the antenna unit currently used by the mobile terminal is P2, the control chip periodically or periodically detects the communication quality of P2, and determines whether the communication quality of P2 meets the preset condition, if the communication quality of P2 meets the preset condition, the communication is continued using P2, if the communication quality of P2 does not meet the preset condition, the single-pole multi-position switch is switched to P30, likewise, the communication quality of P3 is periodically or periodically detected, and determines whether the communication quality of P3 meets the preset condition, if so, the communication is performed using P3, if the communication quality of P3 does not meet the preset condition, the single-pole multi-position switch is switched to P40, and thus the switching is performed in order of P30 → P40 → P10 until the target antenna unit with the communication quality meeting the preset condition in P1-P4 is found, and the target antenna unit is used for communication, so that the influence of the movement of the mobile terminal on the communication between the mobile terminal and the network equipment is reduced. And moreover, the time delay of each transmission channel is the same, namely the time delay from each antenna unit to the radio frequency feed-in point is the same, so that the stability of the time delay in the process of switching the antenna units is ensured, and the user experience is improved.
Alternatively, referring to fig. 4, the patch 10 may be designed as an equilateral hexagon, and the antenna module may include 6 antenna units, which are illustrated by P1, P2, P3, P4, P5, and P6, respectively. The central point of the patch 10 is a radio frequency feed-in point F, 6 antenna units are fixed on the patch 10 according to the position shown in fig. 4, and the antenna module further includes 6 transmission channels, which are P10, P20, P30, P40, P50 and P60 in sequence. The time delays of P10, P20, P30, P40, P50 and P60 are the same. The single-pole multi-position switch is arranged between the radio frequency feed-in point F and the 6 transmission channels and is used for connecting any one transmission channel of the radio frequency feed-in point F and the 6 transmission channels.
It should be noted that: in the case that the patch 10 is designed as an equilateral hexagon, the number of antenna units may be more than 6 as shown in fig. 4, or less than 6 as shown in fig. 4, which is not limited in this application, but it should be noted that: the greater the number of antenna elements, the greater the likelihood of finding an antenna element for which the communication quality meets the requirements.
The switching process of the antenna element is explained below with reference to the design shown in fig. 4:
assuming that the current single-pole multi-position switch is placed on the P30, that is, the P30 is turned on, that is, the antenna unit currently used by the mobile terminal is P3, the control chip periodically or periodically detects the communication quality of the P3, and determines whether the communication quality of the P3 satisfies preset conditions, if the communication quality of the P3 satisfies preset conditions, the communication is continued using the P3, if the communication quality of the P3 does not satisfy preset conditions, the single-pole multi-position switch is switched to the P40, and likewise, the communication quality of the P4 is periodically or periodically detected, and determines whether the communication quality of the P4 satisfies preset conditions, if so, the communication is performed using the P4, if the communication quality of the P4 does not satisfy preset conditions, the single-pole multi-position switch is switched to the P50, and thus the switching is performed in order of P40 → P50 → P60 → P10 → P20 until a target antenna unit of the P1-P6 is found, and the target antenna unit is used for communication, so that the influence of the movement of the mobile terminal on the communication between the mobile terminal and the network equipment is reduced. And moreover, the time delay of each transmission channel is the same, namely the time delay from each antenna unit to the radio frequency feed-in point is the same, so that the stability of the time delay in the process of switching the antenna units is ensured, and the user experience is improved.
When the antenna module comprises the multi-blade multi-position switch, the multi-blade multi-position switch is arranged between the radio frequency feed-in point F and the plurality of transmission channels and used for connecting at least two transmission channels in the radio frequency feed-in point F and the plurality of transmission channels, and the specific connection quantity is flexible equipment according to the MIMO system.
The following introduces the principle of controlling chip to switch antenna units in MIMO scenario:
taking the example that the multi-blade multi-position switch simultaneously connects two transmission channels, the control chip periodically or regularly detects the communication quality of the antenna units corresponding to the two currently connected transmission channels, and determines whether the communication quality meets the preset condition, if so, then the antenna units corresponding to the two transmission channels which are switched on at present are continuously used for communication, if the preset conditions are not met, the multi-blade multi-position switch is switched to a first transmission channel and a second transmission channel, the first transmission channel and the second transmission channel are different, the first transmission channel and the second transmission channel are any one of the plurality of transmission channels, and detecting the communication quality of the antenna units corresponding to the first transmission channel and the second transmission channel in real time, if the communication quality of the antenna units corresponding to the first transmission channel and the second transmission channel meets the preset condition, the antenna units corresponding to the first transmission channel and the second transmission channel are taken as target antenna units. If the communication quality of the antenna units corresponding to the first transmission channel and the second transmission channel does not meet the preset condition, the control chip can be switched to the other two transmission channels through the multi-pole multi-position switch. And the same judgment is made, and the switching is carried out for a plurality of times in sequence until the antenna unit with the communication quality meeting the requirement is found.
Alternatively, in a multi-blade multi-location scenario, the communication quality may be a throughput rate.
In the MIMO communication scheme, Isolation (ISO) and correlation (ECC) between multiple antenna elements affect the overall communication performance of the entire system. Such as wifi, LTE 2 x 2, LTE, 5G 4 x 4 systems. The deterioration of the correlation between the antenna elements results in a decrease in the overall throughput. According to the scheme, the best ISO and ECC antenna can be selected from a plurality of alternative antenna units for communication, so that the communication performance of the whole system is improved.
