At the same time, the term "and / or" used in this specification includes any and all combinations of the relevant listed items.

[0022] In actual applications, an upper antenna and a lower antenna are generally set in the terminal, wherein the upper antenna is generally set in the upper area of ​​the terminal, and the lower antenna is generally set in the lower area of ​​the terminal, wherein the upper antenna and the lower antenna can be connected to the same antenna switching switch to realize the switching of the upper antenna and the lower antenna through the antenna switching switch.

[0023] For example, when held by a user, the upper antenna may be blocked by the user's hand, thereby affecting the state of the antenna. In this case, it is possible to switch to the lower antenna to transmit the RF signal. Or, conversely, the lower antenna may be blocked by the user's hand, thereby affecting the state of the antenna. In this case, it is possible to switch to the upper antenna to transmit the RF signal.

[0024] Please refer to Figure 1 , since the upper antenna and the lower antenna are generally connected to the same antenna switch, and the upper antenna and the lower antenna are set far apart (one is located in the upper area of ​​the terminal, and the other is located in the lower area of ​​the terminal), therefore, one of the upper antenna and the lower antenna ( Figure 1The lower antenna is shown) needs to be connected to the antenna switching switch through a long connecting line. This long connecting line will cause signal loss, especially for high-frequency signals. The connecting line can be, for example, a cable or an FPC (flexible printed circuit board).

[0025] In order to solve this problem, an embodiment of the present application provides an antenna module, which can compensate for the signal loss caused by the longer connecting line and reduce the impact on the signal. Below, the embodiment of the present application will briefly describe the antenna module.

[0026] In one embodiment, Figure 2 As shown, an antenna module is provided, which includes multiple antennas 101, an antenna switching switch 102, multiple radio frequency paths 103, a transceiver 104 and an amplifying circuit 105.

[0027] It should be pointed out that although Figure 2 Only two antennas 101 are shown in the figure, but in actual application, the antenna module provided in the embodiment of the present application may include more than two antennas. In the case where the antenna module includes two antennas 101, the two antennas 101 may include, for example, an upper antenna and a lower antenna. In addition, it should be pointed out that the embodiment of the present application does not limit the type of the antenna 101. For example, in actual application, the antenna 101 may be an inverted F-type antenna, a patch antenna, etc.

[0028] It should also be pointed out that the multiple RF paths 103 may include a RF receiving path and a RF transmitting path, wherein the RF receiving path is used to transmit downlink RF signals, and the RF transmitting path is used to transmit uplink RF signals.

[0029] exist Figure 2 , three RF paths 103 are shown by way of example, which are RF path 1031, RF path 1032 and RF path 1033 from top to bottom. RF path 1031 is a RF transmission path, on which a PA (Power Amplifier) ​​is arranged, RF path 1032 is a RF receiving path, on which an LNA (Low Noise Amplifier) ​​is arranged, RF path 1031 and RF path 1032 are connected to a duplexer, and RF path 1033 is a RF receiving path, on which an LNA and a SAW (Surface Acoustic Wave) filter are arranged.

[0030] It should be pointed out that, in actual applications, the RF path 103 may include more or fewer devices than PA, LNA, SAW, etc., and the embodiments of the present application do not specifically limit this. For example, in some possible embodiments, the RF path 103 may be provided with switches, filters, etc.

[0031] In practical applications, LNA can be divided into two types: eLNA (enhanced Low Noise Amplifier) ​​and iLNA (Intelligent Low Noise Amplifier).

[0032] Among them, iLNA can be understood as LNA integrated inside the receiver, but due to the influence of integration area, its gain and noise coefficient are relatively small, and the adjustable range is also relatively narrow. eLNA can be understood as its parameters and performance-related definitions are consistent with the current LNA, but in the communication system, an additional LNA is added outside the receiver to compensate for the path loss and insufficient iLNA gain. Generally, the gain is relatively large and the adjustable range is relatively wide.

[0033] In the embodiment of the present application, the LNA provided in the RF path 103 may be an eLNA. In addition, in an optional embodiment of the present application, an iLNA may be provided in the receiver 104. Of course, in some embodiments, the iLNA may not be provided in the receiver 104.

[0034] In an optional embodiment of the present application, multiple antennas 101 are connected to a first end of an antenna switch 102, one end of multiple radio frequency paths 103 are connected to a second end of the antenna switch 102, and the other end is connected to a transceiver 104. The antenna switch 102 may be, for example, a single-pole multi-throw switch, and the antenna switch 102 is used to select antennas and radio frequency paths.

[0035] In an optional embodiment of the present application, the receiver 104 or other processors (such as an application processor) can determine which antenna among the multiple antennas 101 is the antenna with the best antenna status, and then, the antenna can be configured to bear uplink transmission. For example, in the case where the multiple antennas 101 include two antennas, the antenna with the best antenna status can be determined from the two antennas, and the antenna can be configured to bear uplink transmission. At the same time, the antenna and another antenna can be configured to bear downlink reception (main diversity reception). The above configuration of the antenna can be achieved by selecting the antenna and the RF path through the antenna switching switch 102.

[0036] In an optional embodiment of the present application, the amplifier circuit 105 is disposed between the first antenna of the plurality of antennas 101 and the antenna switching switch 102. In an optional embodiment of the present application, the first antenna may be, for example, an antenna that needs to be connected to the antenna switching switch 102 through a longer connecting line. For example, when the plurality of antennas 101 include an upper antenna and a lower antenna, the first antenna may be the lower antenna.

[0037] In an optional embodiment of the present application, the amplifier circuit 105 includes a first branch 1051 and a second branch 1052, wherein the first branch 1051 includes an amplifier device and the second branch 1052 does not include an amplifier device, the first branch 1051 is used to transmit a downlink radio frequency signal, and the second branch 1052 is used to transmit an uplink radio frequency signal and / or a downlink radio frequency signal.

[0038] The antenna module provided in this embodiment includes multiple antennas, an antenna switching switch, multiple radio frequency paths, a transceiver and an amplifying circuit, wherein the multiple antennas are connected to the first end of the antenna switching switch, one end of the multiple radio frequency paths is connected to the second end of the antenna switching switch, and the other end is connected to the transceiver, the multiple radio frequency paths include a radio frequency transmitting path and a radio frequency receiving path, the antenna switching switch is used to select the antenna and the radio frequency path, the amplifying circuit is arranged between the first antenna of the multiple antennas and the antenna switching switch, the amplifying circuit includes a first branch and a second branch, wherein the first branch includes an amplifying device, the second branch does not include an amplifying device, and the first branch includes a first branch. One branch is used to transmit downlink radio frequency signals, and the second branch is used to transmit uplink radio frequency signals and / or downlink radio frequency signals. In this way, an amplifier circuit is additionally arranged between the first antenna and the antenna switching switch. The first branch in the amplifier circuit includes an amplifier device, which can amplify the transmitted downlink radio frequency signal, thereby compensating for the signal loss caused by the long connecting line and reducing the impact on the signal. At the same time, the amplifier circuit can also include a second branch, and the second branch can transmit uplink radio frequency signals and / or downlink radio frequency signals. In this way, time-sharing transmission of uplink radio frequency signals and / or simultaneous transmission of uplink radio frequency signals and downlink radio frequency signals can be supported.

[0039] In an optional embodiment of the present application, the amplifier circuit 105 includes a gate switch, wherein the gate switch is connected to the first branch 1051 and the second branch 1052 respectively, wherein the gate switch is used to select the first branch 1051 or the second branch 1052.

[0040] Please refer to Figure 3 , which shows a schematic diagram of an optional amplifier circuit 105, such as Figure 3As shown, the gating switch may include a first gating switch 1053 and a second gating switch 1054, wherein one end of the first gating switch 1053 is connected to the first antenna, and the other end is respectively connected to the first end of the first branch 1051 and the first end of the second branch 1052, and one end of the second gating switch 1054 is respectively connected to the second end of the first branch 1051 and the second end of the second branch 1052, and the other end is connected to the first end of the antenna switching switch 102.

[0041] Please refer to Figure 3 In an optional embodiment of the present application, the amplifier circuit 105 may include a port TRX1 and a port TRX2, wherein the port TRX1 and the port TRX2 are connected by a connecting line, wherein the port TRX1, the port TRX2 and the connecting line between the two ports can be regarded as a second branch 1052.

[0042] In an optional embodiment of the present application, the first selection switch 1053 and the second selection switch 1054 can cooperate with each other to select the first branch 1051 or the second branch 1052 .

[0043] Optionally, when the active end of the first selection switch 1053 is connected to the TRX1 port and the active end of the second selection switch 1054 is connected to the TRX2 port, the first selection switch 1053 and the second selection switch 1054 cooperate with each other to select the second branch 1052 .

[0044] Optionally, when the active end of the first selection switch 1053 is connected to the first end of the first branch 1051 and the active end of the second selection switch 1054 is connected to the second end of the first branch 1051, the first selection switch 1053 and the second selection switch 1054 cooperate with each other to select the first branch 1051.

[0045] In an optional embodiment of the present application, the first selection switch 1053 and the second selection switch 1054 are both connected to the transceiver 104 , and the transceiver 104 is used to control the first selection switch 1053 and the second selection switch 1054 .

[0046] In an optional embodiment of the present application, the amplifying circuit 105 may include a control port EN1, which is connected to the first selection switch 1053 and the second selection switch 1054. The control port EN1 can be externally connected to the transceiver 104, and the transceiver 104 can control the first selection switch 1053 and the second selection switch 1054 through the control port EN1.

[0047] Please refer to Figure 4 , which shows a schematic diagram of another amplifier circuit 105, such as Figure 4As shown, the first branch 1051 includes an amplifying branch 10511 and a pass-through branch 10512. The amplifying branch 10511 includes a low noise amplifier LNA, and the pass-through branch 10512 includes a pass switch. In an optional embodiment of the present application, the amplifying circuit 105 may include a VDD port, which may be connected to an external power supply to power the low noise amplifier LNA.

[0048] In an optional embodiment of the present application, the amplifying branch 10511 may include a capacitor, which can be used for filtering, for example, the capacitor can be used to filter out DC signals. In an optional embodiment of the present application, the through branch 10522 may also include a capacitor, which can be used for filtering similarly to what is described above, for example, the capacitor is used to filter out DC signals.

[0049] It can be understood that when the through switch is turned on, the through branch 10512 is turned on. At this time, the through branch 10512 can cause a short circuit to the amplifying branch 10511. At this time, the amplifying branch 10511 is turned off. When the through switch is turned off, the through branch 10512 is turned off and the amplifying branch 10511 is turned on.

[0050] In an optional embodiment of the present application, the through switch is connected to the transceiver 104, and the transceiver 104 is used to control the on and off of the through switch. In an optional embodiment of the present application, the amplifier circuit 105 may include a control port EN2, which is connected to the through switch, and the control port EN2 can be connected to the transceiver 104 externally, and the control of the through switch by the transceiver 104 can be realized through the control port EN2.

[0051] In an optional embodiment of the present application, the pass switch can be turned on when the power of the downlink RF signal received by the first antenna is greater than a preset power threshold, and can be turned off when the power of the downlink RF signal received by the first antenna is less than or equal to the preset power threshold.

[0052] In an optional embodiment of the present application, the preset power threshold may be pre-set by a technician, and the embodiment of the present application does not specifically limit this.

[0053] In an optional embodiment of the present application, the power of the downlink RF signal received by the first antenna can be determined based on the interaction between the electronic device and the network side. For example, the power of the downlink RF signal received by the first antenna can be determined based on the configuration information sent by the cell when the electronic device accesses the cell.

[0054] It can be understood that if the power of the downlink RF signal received by the first antenna is relatively large, the downlink RF signal can still maintain a relatively high power even if it passes through the loss of the longer connecting line between the first antenna and the antenna switching switch 102, and will not affect the reception and analysis of the downlink RF signal. Therefore, in this case, the direct-through branch 10512 can be turned on, that is, the direct-through switch is turned on, so that the downlink RF signal is not amplified.

[0055] On the contrary, if the power of the downlink RF signal received by the first antenna is relatively small, the power of the downlink RF signal will be attenuated to a lower level after the loss of the longer connecting line between the first antenna and the antenna switching switch 102, which will affect the reception and analysis of the downlink RF signal. Therefore, in this case, the direct-through branch 10512 can be turned off and the amplification branch 10511 can be turned on, that is, the direct-through switch can be turned off to amplify the downlink RF signal.

[0056] In an optional embodiment of the present application, the antenna module can be in a TDD (Time Division Duplexing) working mode and an FDD (Frequency Division Duplexing) working mode. In the TDD working mode, the antenna module can send and receive radio frequency signals in time division. In the FDD working mode, the antenna module can send and receive radio frequency signals at the same time.

[0057] Next, the working modes of the amplifier circuit 105 of the antenna module in the TDD working mode and the FDD working mode will be described respectively.

[0058] 1. The antenna module is in TDD working mode.

[0059] In an optional embodiment of the present application, if the first antenna is configured to undertake only downlink reception, for example, in the case of only two antennas 101, another antenna other than the first antenna is configured to undertake uplink transmission, and the first antenna and the other antenna are configured to undertake downlink reception (main diversity reception). At this time, the first antenna only undertakes downlink reception, and the selection switch can select the first branch 1051, so that the downlink RF signal can be amplified.

[0060] Optionally, the active end of the first gate switch 1053 may be connected to the first end of the first branch 1051 , and the active end of the second gate switch 1054 may be connected to the second end of the first branch 1051 .

[0061] Of course, as described above, when the first branch 1051 is selected, the pass switch in the first branch 1051 can be turned on when the power of the downlink RF signal received by the first antenna is greater than the preset power threshold, and can be turned off when the power of the downlink RF signal received by the first antenna is less than or equal to the preset power threshold.

[0062] In an optional embodiment of the present application, if the first antenna is configured to undertake downlink reception and uplink transmission, for example, in the case of only two antennas 101, the first antenna is configured to undertake uplink transmission, and the first antenna and the other antenna are configured to undertake downlink reception (main diversity reception). At this time, the first antenna undertakes both downlink reception and uplink transmission. The selection switch selects the first branch 1051 during the downlink reception of the first antenna, so that the downlink RF signal can be amplified. In addition, the second branch 1052 is selected during the uplink transmission of the first antenna to transmit the uplink RF signal.

[0063] Optionally, during downlink reception by the first antenna, the active end of the first selection switch 1053 can be connected to the first end of the first branch 1051 , and the active end of the second selection switch 1054 can be connected to the second end of the first branch 1051 .

[0064] Of course, as described above, when the first branch 1051 is selected, the pass switch in the first branch 1051 can be turned on when the power of the downlink RF signal received by the first antenna is greater than the preset power threshold, and can be turned off when the power of the downlink RF signal received by the first antenna is less than or equal to the preset power threshold.

[0065] Optionally, during uplink transmission by the first antenna, the active end of the first selection switch 1053 may be connected to the TRX1 port, and the active end of the second selection switch 1054 may be connected to the TRX2 port.

[0066] 2. The antenna module is in FDD working mode.

[0067] In an optional embodiment of the present application, if the first antenna is configured to undertake only downlink reception, for example, in the case of only two antennas 101, another antenna other than the first antenna is configured to undertake uplink transmission, and the first antenna and the other antenna are configured to undertake downlink reception (main diversity reception). At this time, the first antenna only undertakes downlink reception, and the selection switch can select the first branch 1051, so that the downlink RF signal can be amplified.

[0068] Optionally, the active end of the first gate switch 1053 may be connected to the first end of the first branch 1051 , and the active end of the second gate switch 1054 may be connected to the second end of the first branch 1051 .

[0069] Of course, as described above, when the first branch 1051 is selected, the pass switch in the first branch 1051 can be turned on when the power of the downlink RF signal received by the first antenna is greater than the preset power threshold, and can be turned off when the power of the downlink RF signal received by the first antenna is less than or equal to the preset power threshold.

[0070] In an optional embodiment of the present application, when the first antenna is configured to undertake downlink reception and uplink transmission, for example, when only two antennas 101 are included, the first antenna is configured to undertake uplink transmission, and the first antenna and another antenna are configured to undertake downlink reception (main diversity reception). At this time, the first antenna undertakes both downlink reception and uplink transmission, and the selection switch selects the second branch 1052.

[0071] Optionally, the active end of the first selection switch 1053 may be connected to the TRX1 port, and the active end of the second selection switch 1054 may be connected to the TRX2 port.

[0072] It can be understood that in FDD mode, downlink reception and uplink transmission are performed simultaneously. Therefore, when the first antenna is responsible for both downlink reception and uplink transmission, the second branch 1052 needs to be selected to avoid affecting the uplink transmission.

[0073] In one embodiment, an electronic device is provided, comprising an antenna module as described in any of the above embodiments. The electronic device may be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices, and portable wearable devices. The Internet of Things devices may be smart speakers, smart TVs, smart air conditioners, smart car devices, etc. The portable wearable device may be a smart watch, a smart bracelet, a head-mounted device, etc. The form of the electronic device is not fully exemplified here.

In this specification, the schematic description of the above terms does not necessarily refer to the same embodiment or example.

[0075] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
