The following describes embodiments of the present invention in detail.
When the existing WiFi antenna and main antenna share a common antenna, the WiFi path between the common antenna and the WiFi module must pass through the main set receiving module or diversity receiving module connected to the common antenna, resulting in loss of WiFi signals.
Accordingly, embodiments of the present invention provide an antenna sharing circuit and a mobile terminal, which are described in detail below.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an antenna sharing circuit according to an embodiment of the present invention, as shown in fig. 1, the antenna sharing circuit includes a main antenna 11, an auxiliary antenna 12, a switch 21, a control module 31, a main set receiving module 41, a diversity receiving module 42, a first cellular network module 51, a second cellular network module 52, and a WiFi module 61, where:
the switch 21 includes a first selection terminal 211, a second selection terminal 212, a third selection terminal 213, a main antenna connection terminal 214, an auxiliary antenna connection terminal 215, and a control terminal 216, where the main antenna connection terminal 214 is connected to the main antenna 11, and the auxiliary antenna connection terminal 215 is connected to the auxiliary antenna 12; the first end 411 of the master set receiving module 41 is connected to the first cellular network module 51, and the second end 412 of the master set receiving module 41 is connected to the first selecting end 211; the first end 421 of the diversity receiving module 42 is connected to the second cellular network module 51, the second end 422 of the diversity receiving module 42 is connected to the second selecting end 212, the output end 311 of the control module 31 is connected to the control end 216, and the input end 611 of the WiFi module 61 is connected to the third selecting end 213;
when the WiFi network is used, the control module 31 is configured to control the WiFi module 61 to connect the main antenna 11 or the auxiliary antenna 12 through the switch 21, and to control the main set receiving module 41 to disconnect the main antenna 11 and the auxiliary antenna 12, and to control the diversity receiving module 42 to disconnect the main antenna 11 and the auxiliary antenna 12.
The antenna sharing circuit in the embodiment of the present invention is used in mobile terminals such as mobile phones, and when the master receiver module 41 is connected to the master antenna 11 through the switch 21, the master receiver module 41 receives a radio frequency signal from the master antenna 11, and transmits the received radio frequency signal to the first cellular network module 51 after performing filtering processing and amplification processing. If the mobile terminal supports a 4G mobile network, the first cellular network module 51 may be a Long Term Evolution (LTE) module. When the main set receiving module 41 is connected to the auxiliary antenna 12 through the switch 21, the main set receiving module 41 receives the radio frequency signal from the auxiliary antenna 12, and transmits the received radio frequency signal to the first cellular network module 51 after performing filtering processing and amplification processing. The diversity receiving module 42 is a radio frequency receiving module added for canceling the influence of fast fading on the received signal, and since the signal generates multipath component signals due to interference such as reflection during transmission, the mobile terminal can receive signals of different paths simultaneously by using the main antenna and the auxiliary antenna, and then select and combine these signals into an overall signal to mitigate the influence of signal fading. In short, using both the main set receiving module 41 and the diversity receiving module 42 means to combine the signals received by the main set receiving module 41 and the diversity receiving module 42, and as long as several signals are independent from each other, the maximum signal gain can be obtained after proper combination.
Optionally, the first cellular network module 51 includes any one of a long term evolution LTE module, a time Division-Synchronous Code Division Multiple Access (TD-SCDMA) module, a Wideband Code Division Multiple Access (WCDMA) module, and a global system for Mobile Communication (GSM) module; the second cellular network module 52 includes any one of an LTE module, a TD-SCDMA module, a WCDMA module, and a GSM module.
Wherein, if the first cellular network module 51 includes an LTE module, it indicates that the mobile terminal supports a 4G network, if the first cellular network module 51 includes a TD-SCDMA module or a WCDMA module, it indicates that the mobile terminal supports a 3G network, and if the first cellular network module 51 includes a GSM module, it indicates that the mobile terminal supports a 2G network.
When the main set receiving module 41 is connected to the main antenna 11 through the switch 21, the diversity receiving module 42 is connected to the auxiliary antenna 12 through the switch 21, the main set receiving module 41 and the diversity receiving module 42 perform filtering and amplification on the received radio frequency signals and transmit the radio frequency signals to the first cellular network 51 and the second cellular network 52, and the first cellular network 51 and the second cellular network 52 combine the received radio frequency signals, so that the signal gain of the combined radio frequency signals is maximized.
Generally, the main set receiving module 41 is connected to the main antenna 11 through the switch 21, and the diversity receiving module 42 is connected to the auxiliary antenna 12 through the switch 21, when the signal received by the main antenna 11 is weak and the signal received by the auxiliary antenna 12 is strong, the switch 21 can switch the main set receiving module 41 to be connected to the auxiliary antenna 12, and the diversity receiving module 42 to be connected to the main antenna 11. It should be noted that the main antenna 11 cannot be simultaneously communicated with the main set receiving module 41 and the diversity receiving module 21, and the auxiliary antenna 12 cannot be simultaneously communicated with the main set receiving module 41 and the diversity receiving module 21. At the same time point, the main antenna 11 can only be connected with one of the main set receiving module 41, the diversity receiving module 42, and the WiFi module 61, and the auxiliary antenna 12 can only be connected with one of the main antenna 11, the main set receiving module 41, the diversity receiving module 42, and the WiFi module 61, and at the same time point, the modules connected with the main antenna 11 and the auxiliary antenna 12 are different.
In the embodiment of the present invention, the WiFi module 61, the first cellular network module 51, and the second cellular network module 52 share two antennas (the main antenna 11 and the auxiliary antenna 12). When the WiFi network is used, the control module 31 is configured to control the WiFi module 61 to connect the main antenna 11 or the auxiliary antenna 12 through the switch 21, and to control the main set receiving module 41 to disconnect the main antenna 11 and the auxiliary antenna 12, and to control the diversity receiving module 42 to disconnect the main antenna 11 and the auxiliary antenna 12. Because in the antenna sharing circuit of fig. 1, the WiFi module 61 can be directly communicated with the main antenna 11 or the auxiliary antenna 12 through the switch 21, a WiFi path between the WiFi module and the main antenna 11 or the auxiliary antenna 12 can be established between the switches, the WiFi path does not pass through the main set receiving module 41 and the diversity receiving module 42, the WiFi signal only needs to pass through the switch, and does not need to pass through the main set receiving module 41 and the diversity receiving module 42, compared with the prior art in which the WiFi signal needs to pass through the main set receiving module and the diversity receiving module when sharing an antenna, the WiFi signal loss can be reduced, and the WiFi path insertion loss is reduced.
Optionally, the control module 31 is configured to control the WiFi module 61 to connect the main antenna 11 or the auxiliary antenna 12 through the switch 21, and to control the main set receiving module 41 to disconnect from the main antenna 11 and the auxiliary antenna 12, and to control the diversity receiving module 42 to disconnect from the main antenna 11 and the auxiliary antenna 12, specifically:

The control ends of the first switch tube, the second switch tube, the third switch tube, the fourth switch tube, the fifth switch tube and the sixth switch tube may be respectively connected to six control ends 216 of the switch. At the same time, the control module 31 controls at most two of the six switching tubes to be in a conducting state.

In the embodiment of the present invention, the switch 21 may be a three-pole double-throw switch. The specific connection condition of the switch 21 in the embodiment of the present invention can be seen in fig. 2d, where in fig. 2d, the main set receiving module 41 is connected to the main antenna 11, and the diversity receiving module 42 is connected to the auxiliary antenna 12; optionally, the main set receiving module 41 is connected to the auxiliary antenna 12, and the diversity receiving module 42 is connected to the main antenna 11. In fig. 2d, the WiFi module 61 cannot be connected to the main antenna 11 and the auxiliary antenna 12.
By implementing the antenna sharing circuit shown in fig. 1, WiFi signals only need to pass through the switch, and do not need to pass through the main set receiving module and the diversity receiving module, so that WiFi signal loss can be reduced, and WiFi access insertion loss can be reduced.
Referring to fig. 3, fig. 3 is a schematic structural diagram of another antenna sharing circuit disclosed in the embodiment of the present invention, and as shown in fig. 3, the antenna sharing circuit includes a main antenna 11, an auxiliary antenna 12, a switch 21, a control module 31, a main set receiving module 41, a diversity receiving module 42, a first cellular network module 51, a second cellular network module 52, and a WiFi module 61, where:
the switch 21 includes a first selection terminal 211, a second selection terminal 212, a third selection terminal 213, a main antenna connection terminal 214, an auxiliary antenna connection terminal 215, and a control terminal 216, where the main antenna connection terminal 214 is connected to the main antenna 11, and the auxiliary antenna connection terminal 215 is connected to the auxiliary antenna 12; the first end 411 of the master set receiving module 41 is connected to the first cellular network module 51, and the second end 412 of the master set receiving module 41 is connected to the first selecting end 211; the first end 421 of the diversity receiving module 42 is connected to the second cellular network module 51, the second end 422 of the diversity receiving module 42 is connected to the second selecting end 212, the control module 31 includes an output end 311 and a signal input end 312, the output end 311 of the control module 31 is connected to the control end 216, and the input end 611 of the WiFi module 61 is connected to the third selecting end 213; the signal input end 312 is connected with the signal detection end 612 of the WiFi module 61;

When the control module 31 detects that the strength of the signal received by the WiFi module 61 is weak, the antenna connected to the WiFi module 61 may be switched. For example, when the WiFi module 61 is connected to the main antenna 11, if the control module 31 detects that the signal strength received by the WiFi module 61 is less than the preset signal strength threshold (for example, the preset signal strength threshold may be set to-90 dbm), the control module 31 controls the WiFi module 61 to connect to the auxiliary antenna 12 and disconnect from the main antenna 11. See in particular fig. 4 a.
For example, when the WiFi module 61 is connected to the secondary antenna 12, if the control module 31 detects that the signal strength received by the WiFi module 61 is less than the preset signal strength threshold (for example, the preset signal strength threshold may be set to-90 dbm), the control module 31 controls the WiFi module 61 to connect to the main antenna 11 and disconnect from the secondary antenna 12. See in particular fig. 4 b.
By implementing the antenna sharing circuit shown in fig. 3, WiFi signals only need to pass through the switch, and do not need to pass through the main set receiving module and the diversity receiving module, so that WiFi signal loss can be reduced, and WiFi access insertion loss can be reduced. And the WiFi module can select the antenna with stronger WiFi signal strength in the main antenna 11 and the auxiliary antenna 12 through the switch, so as to improve the signal strength of the antenna connected with the WiFi module.
