Detailed Description
In order that the above objects, features and advantages of the application will be readily understood, a more particular description of the application will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. The present application may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the application, whereby the application is not limited to the specific embodiments disclosed below.
In the description of the present application, it should be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature. In the description of the present application, the meaning of "plurality" means at least two, for example, two, three, etc., unless specifically defined otherwise.
The radio frequency component related to the embodiment of the application can be applied to electronic equipment with a wireless communication function. The electronic device may specifically be a User Equipment (UE), an access terminal, a terminal unit, a terminal station, a mobile station, a remote terminal, a mobile device, a wireless communication device, a terminal agent, a terminal apparatus, or the like. An access terminal may be a cellular telephone, a cordless telephone, a session initiation protocol (session initiation protocol) telephone, a wireless local loop (wireless local loop, WLL) station, a Personal Digital Assistant (PDA), a handset, a computer, a laptop computer, a handheld computing device (e.g., a tablet), and other devices for communicating over a wireless system.
As shown in fig. 1, an electronic device 10 in an embodiment of the present application may support cellular, wiFi wireless communications, short range wireless communications, and the like. For ease of illustration, the electronic device 10 is illustrated as supporting WiFi wireless communications. In general, one complete WiFi wireless communication is duplex communication. It will be appreciated that the electronic device 10 is capable of receiving the WiFi signal sent by the communication device 20, and at the same time, the communication device 20 is also required to be capable of receiving the WiFi signal sent by the electronic device 10, so that a complete WiFi wireless communication can be achieved. For ease of description, the communication device 20 is taken as a router, and the electronic device 10 is taken as a mobile phone. From the user perspective, the path between the router and the mobile is called a downlink Link, and the coverage area is called a router coverage area, as shown by the solid line in fig. 1. The path from router to router is called uplink Up Link and its Coverage area is called handset Coverage, as indicated by the dashed line in fig. 1.
Table 1 shows the regulatory standards established for SAR certification in various countries and regions. Two of the main regulatory requirements are the standard 1.6W/Kg (1 g) adopted by the Federal communications Commission (Federal Communications Commission, FCC) in the United states and the standard 2.0W/Kg (10 g) adopted by European CE.
TABLE 1 major national and regional SAR regulatory requirements
Table 2 shows the regulatory standards set for EIRP in major countries and regions of the world, the most stringent of which is the European CE standard. The WiFi signals may include WiFi-2.4GHz signals and WiFi-5GHz signals, wherein WiFi-2.4GHz and WiFi-5GHz are both industry open frequency bands, so that maximum transmission power (Peak-EIRP) of devices needs to be limited to prevent mutual interference between the devices.
TABLE 2 major national and regional EIRP regulatory requirements
In general, the mobile phone transmission power is limited due to the limitation of the specific absorption rate and the equivalent omnidirectional radiation power, and the uplink and downlink of the mobile phone are asymmetric, as shown in fig. 1, the uplink of the mobile phone is limited.
In addition to the influence of regulations such as SAR and EIRP, another factor limiting the transceiving performance of the electronic device 10 is that the antenna of the electronic device 10 is blocked, e.g., held by the head-hand or the like, resulting in deterioration of the antenna performance. For example, if the antenna of the electronic device 10 is laid out on the frame, the holding gesture of different users is different, and if the antenna is just held and blocked, the performance of the antenna may be seriously deteriorated, and finally the WiFi wireless communication fails. After a certain antenna is held by hand, the antenna performance may be reduced by 10-15 dB compared with the free space performance, and at this time, if the antenna is in a weak signal, communication failure is likely to be caused, which seriously affects user experience.
In view of the above technical problems, embodiments of the present application provide a radio frequency assembly and an electronic device, which can support WiFi wireless communication, reduce EIRP and SAR under the condition that input power is not retracted, so as to meet the requirements of response regulations, and simultaneously avoid the situation that each antenna in the electronic device is simultaneously held, so as to improve the communication performance of the uplink of the radio frequency assembly and the electronic device.
The application provides a radio frequency assembly. As shown in fig. 2 and 3, the radio frequency assembly 100 in one embodiment of the present application includes: a wireless fidelity module 110 and at least one radio frequency front end module 120. The wireless fidelity module 110 includes at least one first rf port and at least one second rf port, where the number of the first rf ports and the number of the second rf ports may be the same or different. For convenience of explanation, in the embodiment of the present application, the case where the number of the first rf ports and the second rf ports are equal (or the first rf ports and the second rf ports are arranged in pairs) is taken as an example. The first radio frequency port is used for transmitting a first wireless fidelity signal, and the second radio frequency port is used for transmitting a second wireless fidelity signal. The frequency bands of the first wireless fidelity signal and the second wireless fidelity signal are different, for example, the first wireless fidelity signal can be a Wi-Fi 2.4GHz signal, the second wireless fidelity signal can be a Wi-Fi5GHz signal, or the first wireless fidelity signal can be a Wi-Fi5GHz signal, and the second wireless fidelity signal can be a Wi-Fi 2.4GHz signal.
Optionally, the wireless fidelity module 110 may include at least one of a USB interface WiFi module, an ethernet interface, a UART interface serial port WiFi module, an SDIO interface WiFi module, and a WCN module. For example, the wireless fidelity module 110 may be a wireless communication network (Wireless Communication Network, WCN) module, where the WCN module implements at least one wireless communication function, such as Wi-Fi wireless communication, bluetooth wireless communication, FM (frequency modulation) wireless communication, global positioning system (Global Positioning System, GPS) wireless communication, and the like.
In the embodiment of the present application, the number of the rf front-end modules 120 is the same as the number of the first rf ports or the second rf ports. The two first ends of each rf front-end module 120 are respectively connected with a first rf port and a second rf port, and the two second ends of each rf front-end module 120 are respectively connected with two antennas. It can be appreciated that the number of rf front-end modules 120, the number of first rf ports, and the number of second rf ports are equal, respectively. The first radio frequency ports or the second radio frequency ports connected with the first ends of the radio frequency front end modules are different. The antennas connected to the second ends of the same radio frequency front end module are different, and the antennas connected to the second ends of different radio frequency front end modules are also different. It is understood that the total number of antennas included in the electronic device 10 is twice the total number of rf front-end modules 120.
The rf front-end module 120 is configured to pre-process the received first wireless fidelity signal and second wireless fidelity signal to output two paths of dual-band signals to two antennas correspondingly connected. It can be understood that each rf front-end module 120 can receive a first wireless fidelity signal from a first rf port and a second wireless fidelity signal from a second rf port, and perform preprocessing on the received first wireless fidelity signal and second wireless fidelity signal, and after preprocessing, the rf front-end module 120 can output two paths of dual-band signals to two antennas correspondingly connected. Wherein each of the dual-band signals includes a first wireless fidelity signal and a second wireless fidelity signal, for example, the dual-band signals may include a WiFi 2.4G signal and a WiFi 5G signal. One of the dual-band signals is output to an antenna connected to a second end of the rf front-end module 120, and the other dual-band signal is output to another antenna connected to another second end of the rf front-end module 120. The preprocessing comprises the steps of combining the received first wireless fidelity signal and the received second wireless fidelity signal and processing the received second wireless fidelity signal. In the embodiment of the present application, the order of the combining process and the power dividing process in the preprocessing is not limited.
In the embodiment of the present application, the rf module 100 includes a wireless fidelity module 110 and at least one rf front-end module 120, wherein the rf front-end module 120 can combine and process the received first wireless fidelity signal and the second wireless fidelity signal to output two dual-band signals. The rf front-end module 120 may perform power division processing on the first wireless fidelity signal and the second wireless fidelity signal provided by the wireless fidelity module 110, so that power of each wireless fidelity signal in the dual-band signal may be reduced, and further, transmit power of each antenna may be reduced, so that transmit power distribution is relatively uniform, and thus SAR and Peak EIRP may be reduced, so as to meet requirements of safety-related regulations. For example, after preprocessing, the power of the first wireless fidelity signal in the dual-band signal is lower than the power of the first wireless fidelity signal received by the rf front-end module 120 from the wireless fidelity module 110, and the power of the second wireless fidelity signal in the dual-band signal is lower than the power of the second wireless fidelity signal received by the rf front-end module 120 from the wireless fidelity module 110.
In addition, the rf front-end module 120 may output two paths of dual-band signals to two antennas correspondingly connected, even if one of the two antennas is blocked, it can ensure that one path of dual-band signals can be normally transmitted to the non-blocked antenna, so that when the electronic device 10 is held by a user, the probability of blocking all the antennas to greatly reduce the wireless performance can be reduced, and the communication performance of wireless communication can be improved. The radio frequency component 100 provided in the embodiment of the present application is the same as the omnidirectional radiation power (Total Radiated Power, TRP) of the radio frequency component 100 in the related art, and the Peak EIRP of the radio frequency component 100 provided in the embodiment of the present application can be reduced by 3dB compared with the radio frequency component 100 in the related art, and in engineering practice, the Peak EIRP can also be reduced by about 1 to 2 dB. In addition, in the radio frequency assembly 100 provided by the present embodiment, the maximum SAR of a single antenna can be reduced by 3dB.
In the embodiment of the present application, the rf assembly 100 may include one rf front-end module 120, or may include two rf front-end modules 120. The number of rf front-end modules 120 is different, and the operation mode of the rf assembly 100 is different. The operation modes of the rf assembly 100 may include SISO (simple input simple output, single input single output) mode and MIMO (Multiple Input Multiple Output), multiple input multiple output) mode, among others. Generally, in the embodiment of the present application, if the rf device 100 includes an rf front-end module 120, the rf device 100 may support SISO mode. In the SISO mode, the number of radio frequency devices (e.g., power dividing units, combining units) included in the radio frequency assembly 100 may be reduced, and the cost may be reduced, and at the same time, the communication performance of the WiFi signal may also be ensured. If the RF assembly 100 includes two RF front end modules 120, the RF assembly 100 may support MIMO mode. In the MIMO mode, the frequency spectrum utilization rate can be increased by times, the channel capacity can be increased by times, the reliability of the channel can be improved, and the error rate can be reduced under the condition that the bandwidth and the antenna transmitting power are not increased.
The SISO mode and MIMO mode of the rf assembly 100 are described in detail below in conjunction with the internal structure of the rf front-end module 120.
In one embodiment, as shown in fig. 4 and fig. 5, the preprocessing of the rf front-end module 120 may include combining the first wireless fidelity signal and the second wireless fidelity signal, and then performing power processing on the combined signals to output two dual-band signals. Optionally, the preprocessing of the rf front-end module 120 may include performing power division processing on the first wireless fidelity signal and the second wireless fidelity signal, and then performing combining processing on the signals after the power division processing to output two paths of dual-band signals. Specifically, the rf front-end module 120 includes a power dividing module 121 and a combining module 122 connected to the power dividing module 121, where one of the power dividing module 121 and the combining module 122 is connected to a first rf port and a second rf port of the wireless fidelity module 110, and the other one of the power dividing module 121 and the combining module 122 is correspondingly connected to two antennas.
Optionally, the input end of the power dividing module 121 is connected to the first rf port and the second rf port of the wireless fidelity module 110, respectively, the output end of the power dividing module 121 is connected to the input end of the combining module 122, and the output ends of the combining module 122 are correspondingly connected to two antennas, respectively, see fig. 4. Thus, the preprocessing of the rf front-end module 120 may include the processing of first power division and then combining.
Alternatively, as shown in fig. 5, the input end of the combining module 122 is connected to the first rf port and the second rf port of the wireless fidelity module 110, respectively, the output end of the combining module 122 is connected to the input end of the power dividing module 121, and the output end of the power dividing module 121 is correspondingly connected to two antennas, see fig. 5. Thus, the preprocessing of the rf front-end module 120 may include combining processing before processing.
It should be noted that, the connection manner of the combining module 122 and the power dividing module 121 configured in the rf front-end module 120 determines the sequence of the combining process and the power dividing process in the preprocessing.
The preprocessing of the rf front-end module 120 may include processing steps of power splitting and combining. In one embodiment, as shown in fig. 6, the rf module 100 includes an rf front-end module 120, and the rf module 100 may support SISO mode. The power dividing module in the rf front-end module 120 includes a first power dividing unit 1211 and a second power dividing unit 1212, and the reasonable module in the rf front-end module 120 includes a first combining unit 1221 and a second combining unit 1222. In the uplink, the first end of the first power dividing unit 1211 is used as a first end of the rf front-end module 120, and the first power dividing unit 1211 is configured to divide the received first wireless fidelity signal into two paths and output the two paths to the first combining unit 1221 and the second combining unit 1222 correspondingly. The first end of the second power dividing unit 1212 is used as another first end of the rf front-end module 120, and the second power dividing unit 1212 is configured to divide the received second wireless fidelity signal into two paths and output the two paths to the first combining unit 1221 and the second combining unit 1222 respectively. The first combining unit 1221 is configured to perform a combining process on the received first wireless fidelity signal and the received second wireless fidelity signal, and output a first dual-band signal to the first antenna. The second combining unit 1222 is configured to combine the received second wireless fidelity signal and the second wireless fidelity signal, and output a second dual-band signal to the second antenna.
A first transmission path for transmitting a first wireless fidelity signal may be formed between the first power dividing unit 1211 and the first rf port of the wireless fidelity module 110, and a second transmission path for transmitting a second wireless fidelity signal may be formed between the second power dividing unit 1212 and the second rf port of the wireless fidelity module 110. It will be appreciated that the number of first transmission paths and second transmission paths formed in the rf assembly 100 is 1, respectively, which can support both transmit and receive processing of one first wireless fidelity signal and one second wireless fidelity signal, which can operate in SISO mode.
Further, the first end of the first power dividing unit 1211 is connected to the first rf port, and the two second ends of the first power dividing unit 1211 are respectively connected to a first end of the first combining unit 1221 and a first end of the second combining unit 1222 correspondingly; the first end of the second power dividing unit 1212 is connected with a second radio frequency port, and the two second ends of the second power dividing unit 1212 are respectively correspondingly connected with the other first end of the first combining unit 1221 and the other first end of the second combining unit 1222; the second end of the first combining unit 1221 is used for being connected with the first antenna ANT 1; the second terminal of the second combining unit 1222 is for connection with a second antenna ANT 2.
Alternatively, the first power dividing unit 1211 and the second power dividing unit 1212 may be equal power divided power dividers, or unequal power divided power dividers. The power divider may divide the power divider into N power dividers, where N is a positive integer greater than or equal to 2. The power divider can be a microstrip power divider, a cavity power divider and the like.
The power divider is exemplified as a one-to-N power divider.

As shown in fig. 10, an embodiment of the present application further provides an electronic device 10, including the radio frequency assembly 100 and at least two antennas in any of the foregoing embodiments. Two second ends of each rf front-end module 120 in the rf assembly 100 are respectively connected to two antennas.
Optionally, the antenna provided in the embodiment of the present application may support the reception and transmission of WiFi signals. The antenna provided in the embodiment of the application may be one of a flexible circuit board (Flexible Printed Circuit) antenna, a Laser Direct Structuring (LDS) antenna, a Printed Direct Structuring (PDS) antenna, a radiation patch and a metal radiation branch antenna. In the embodiment of the application, the type of the antenna is not further limited. In embodiments of the present application, an appropriate antenna type may be selected based on the particular type of electronic device 10.
In the electronic device 10 of the embodiment of the present application, by setting the rf module 100, the rf front-end module 120 may perform combining and power processing on the received first wireless fidelity signal and the second wireless fidelity signal to output two paths of dual-band signals, where the power of the first wireless fidelity signal in the dual-band signal is lower than the power of the first wireless fidelity signal received by the rf front-end module 120 from the wireless fidelity module 110, and the power of the second wireless fidelity signal in the dual-band signal is lower than the power of the second wireless fidelity signal received by the rf front-end module 120 from the wireless fidelity module 110, so that the power of each wireless fidelity signal in the dual-band signal can be reduced, and further the transmitting power of each antenna can be reduced, so that the transmitting power distribution is relatively uniform, and the SAR and Peak EIRP are reduced to meet the requirements of safety-related regulations. In addition, the rf front-end module 120 may output two paths of dual-band signals to two antennas correspondingly connected, even if one of the two antennas is blocked, it can ensure that one path of dual-band signals can be normally transmitted to the non-blocked antenna, so that when the electronic device 10 is held by a user, the probability of blocking all the antennas to greatly reduce the wireless performance can be reduced, and the communication performance of WiFi wireless communication can be improved. For example, if the electronic device 10 in the related art only has one WiFi antenna to support WiFi dual band signal communication, but the embodiment of the present application has two antennas to support WiFi dual band signal communication, the comparison of the two antennas in the same hand-held scenario (e.g., one antenna is blocked) is shown in table 3.
Table 3 is a comparative data table of the effects of hand-held scenes in accordance with the related art and embodiments of the present application
Frequency band | Free space | Related art hand-held scenarios | The embodiment of the application holds the scene |
WiFi 2.4G | -5dB | -20dB | -10dB |

Therefore, the electronic device 10 provided by the embodiment of the application greatly reduces the possibility that two antennas are simultaneously held in a normal holding gesture, and the hand holding influence is about 3-5 dB and less than the influence of 10-15 dB. Obviously, the communication performance of WiFi wireless communication can be greatly improved.
In the embodiment of the present application, the electronic device 10 includes a radio frequency assembly 100, a first antenna ANT1 and a second antenna ANT2, where the first antenna ANT1 and the second antenna ANT2 are respectively disposed on two sides of the electronic device 10 that are adjacently disposed.

For example, the sides of the electronic device 10 that are disposed adjacent may include sides of the top of the electronic device 10 and sides of the sides adjacent to the top. Alternatively, the two sides of the electronic device 10 disposed adjacently may include the side on which the bottom of the electronic device 10 is located, and the side adjacent to the bottom.
Alternatively, the first antenna ANT1 and the second antenna ANT2 are respectively disposed at two opposite sides of the electronic device 10, and the radiation patterns of the first antenna ANT1 and the radiation patterns of the second antenna ANT2 exhibit complementary characteristics. For example, the first antenna ANT1 may be located on the top side of the electronic device 10, and the second antenna ANT2 may be located on the bottom side of the electronic device 10. The radiation patterns generated when the first antenna ANT1 and the second antenna ANT2 transmit the WiFi signal may cover different spaces, and the radiation patterns of the first antenna ANT1 and the second antenna ANT2 may be complementary, so that the electronic device 10 may implement the omni-directional characteristic of the specific plane even in the case where the headroom area of the first antenna ANT1 and the second antenna ANT2 is small.

The second antenna ANT2 and the fourth antenna ANT4 are respectively disposed at two opposite sides of the electronic device 10, and the radiation patterns of the second antenna ANT2 and the radiation patterns of the fourth antenna ANT4 exhibit complementary characteristics.
In the embodiment of the application, the first antenna ANT1, the second antenna ANT2, the third antenna ANT3 and the fourth antenna ANT4 are respectively arranged on different sides of the terminal, so that the radiation patterns are complementary in all angles, the zero points of the patterns are fewer, and the probability of simultaneous failure is greatly reduced. Specifically, fig. 12 is a radiation pattern synthesized by two WiFi antennas in a related technical solution, and fig. 13 is a radiation pattern synthesized by four WiFi antennas in an embodiment of the present application. Wherein fig. 2 and 13 are two-dimensional radiation patterns, the abscissa thereof is used for characterizing the direction angle Phi (Phi), and the ordinate thereof is used for characterizing the direction angle Theta (Theta). As can be seen from a comparison of the two graphs, the resultant radiation pattern of fig. 10 is less omnidirectional, the highest and lowest directions differ significantly, while the radiation pattern of fig. 11 is more evenly distributed over 360 °.
In the embodiment of the present application, different types of antennas may be set according to the type of the electronic device 10, for example, the device type of the mobile phone, the tablet, the client front-end device, the router, and the like. For example, the four WiFi antennas (e.g., metal stub antennas) shown in fig. 14 may be applied in mobile phones, tablet, and other electronic devices.
