随着技术的发展,具有通信功能的电子设备(例如,手机、平板等)的普及度越来越高,且功能越来越强大。但是与此同时,关于电子设备安全性及合规要求也更加严格。例如,比吸收率(Specific absorption rate,SAR)和等效全向辐射功率(EquivalentIsotropically Radiated Power,EIRP)是无线保真(Wireless Fidelity,WiFi)通信的两个常见的安全法规认证项目。With the development of technology, electronic devices with communication functions (such as mobile phones, tablets, etc.) are becoming more and more popular and more powerful. But at the same time, the safety and compliance requirements for electronic devices are also more stringent. For example, Specific absorption rate (SAR) and Equivalent Isotropically Radiated Power (EIRP) are two common safety regulatory certification items for Wireless Fidelity (WiFi) communications.

因此,如何在确保WiFi无线通信性能的前提下,还能够满足相关安全法规成为亟待解决的问题。Therefore, how to ensure the performance of WiFi wireless communication while meeting relevant safety regulations has become an urgent problem to be solved.

In addition, the radio frequency front-end module can output two dual-band signals to the two correspondingly connected antennas, even if one of the antennas is blocked, it can ensure that one dual-band signal can be normally transmitted to the unblocked antenna, which can reduce the probability of significantly reducing the wireless performance due to blocking all antennas when the electronic device is held by the user, and can improve the communication performance of wireless communication.

具体实施方式Detailed ways

为使本申请的上述目的、特征和优点能够更加明显易懂,下面结合附图对本申请的具体实施方式做详细的说明。在下面的描述中阐述了很多具体细节以便于充分理解本申请。但是本申请能够以很多不同于在此描述的其它方式来实施,本领域技术人员可以在不违背本申请内涵的情况下做类似改进,因此本申请不受下面公开的具体实施例的限制。In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

在本申请的描述中,需要理解的是,术语“第一”、“第二”仅用于描述目的,而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此,限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。在本申请的描述中,“多个”的含义是至少两个,例如两个,三个等,除非另有明确具体的限定。In the description of the present application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present application, "plurality" means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

本申请实施例涉及的射频组件可以应用到具有无线通信功能的电子设备。电子设备具体可以是用户设备(user equipment,UE)、接入终端、终端单元、终端站、移动站、移动台、远方站、远程终端、移动设备、无线通信设备、终端代理或终端装置等。接入终端可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol,SIP)电话、无线本地环路(wireless local loop,WLL)站、个人数字处理(personal digital assistant,PDA)、手机、电脑、膝上型计算机、手持式计算设备(例如平板)、以及用于在无线系统上进行通信的其它设备。The radio frequency components involved in the embodiments of the present application can be applied to electronic devices with wireless communication functions. The electronic device can specifically be user equipment (UE), access terminal, terminal unit, terminal station, mobile station, mobile station, remote station, remote terminal, mobile device, wireless communication device, terminal agent or terminal device, etc. The access terminal can be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a mobile phone, a computer, a laptop computer, a handheld computing device (such as a tablet), and other devices for communicating on a wireless system.

如图1所示,本申请实施例中的电子设备10可支持蜂窝、WiFi无线通信、短距离无线通信等。为了便于说明,以电子设备10支持WiFi无线通信为例进行说明。一般来说,一个完整的WiFi无线通信为双工通信。可以理解,电子设备10能接收到通信设备20发来的WiFi信号,同时,也要求通信设备20能接收到电子设备10发来的WiFi信号,如此,才能够实现一次完整的WiFi无线通信。为了便于说明,以通信设备20为路由器、电子设备10为手机为例进行说明。其中,从用户角度上看,路由器到手机之间的通路称之为下行链路Down Link,其覆盖范围称之为路由器覆盖范围,如图1中实线所示区域。路由器到路由器之间的通路称之为上行链路Up Link,其覆盖范围称之为手机Coverage,如图1中虚线所示区域。As shown in FIG1 , the electronic device 10 in the embodiment of the present application can support cellular, WiFi wireless communication, short-range wireless communication, etc. For the sake of convenience, the electronic device 10 supports WiFi wireless communication as an example. Generally speaking, a complete WiFi wireless communication is duplex communication. It can be understood that the electronic device 10 can receive the WiFi signal sent by the communication device 20, and at the same time, the communication device 20 is also required to receive the WiFi signal sent by the electronic device 10, so that a complete WiFi wireless communication can be achieved. For the sake of convenience, the communication device 20 is a router and the electronic device 10 is a mobile phone as an example. Among them, from the user's perspective, the path between the router and the mobile phone is called the downlink Down Link, and its coverage is called the router coverage, as shown in the solid line area in FIG1. The path between routers is called the uplink Up Link, and its coverage is called the mobile phone Coverage, as shown in the dotted line area in FIG1.

表1所示为各个国家和地区针对SAR认证所制定的法规标准。其中主要的法规要求有两个,一个是美国联邦通信委员会(Federal Communications Commission,FCC)采用的标准1.6W/Kg(1g),另一个是欧洲CE采用的标准2.0W/Kg(10g)。Table 1 shows the regulatory standards for SAR certification in various countries and regions. There are two main regulatory requirements, one is the standard 1.6W/Kg (1g) adopted by the Federal Communications Commission (FCC) of the United States, and the other is the standard 2.0W/Kg (10g) adopted by the European CE.

表1主要国家和地区SAR法规要求Table 1 SAR regulatory requirements in major countries and regions

表2所示为全球主要国家和地区针对EIRP制定的法规标准,其中最为严苛的是欧洲CE标准。WiFi信号可包括WiFi-2.4GHz信号和WiFi-5GHz信号,其中,WiFi-2.4GHz和WiFi-5GHz均为工业开放频段,因此,需要对设备最大发射功率(Peak-EIRP)进行限制,以防设备之间出现相互干扰。Table 2 shows the regulatory standards for EIRP set by major countries and regions around the world, of which the most stringent is the European CE standard. WiFi signals can include WiFi-2.4GHz signals and WiFi-5GHz signals, of which WiFi-2.4GHz and WiFi-5GHz are both industrial open frequency bands. Therefore, it is necessary to limit the maximum transmit power (Peak-EIRP) of the device to prevent mutual interference between devices.

表2主要国家和地区EIRP法规要求Table 2 EIRP regulatory requirements in major countries and regions

通常,由于比吸收率和等效全向辐射功率等法规要求限制,导致手机发射功率受限,导致手机上行链路和下行链路不对称,如图1所示,手机上行链路受限。Typically, due to regulatory requirements such as specific absorption rate and equivalent isotropic radiated power, the transmit power of a mobile phone is limited, resulting in an asymmetry between the uplink and downlink of the mobile phone. As shown in Figure 1, the uplink of the mobile phone is limited.

除了SAR和EIRP等法规的影响,限制电子设备10收发性能的另一个因素是电子设备10的天线被遮挡,例如头手等握持,导致天线性能的恶化。示例性的,若电子设备10的天线布局在边框上,不同的用户握姿不同,如果天线正好被握住遮挡,可能导致天线性能严重恶化,最终WiFi无线通信失败。某个天线在被手握住之后,相比于自由空间性能,天线性能可能下降10~15dB,此时如果处在弱信号下,很可能造成通信失败,严重影响用户体验。In addition to the impact of regulations such as SAR and EIRP, another factor that limits the transceiver performance of the electronic device 10 is that the antenna of the electronic device 10 is blocked, such as when held by the head or hand, which leads to deterioration of the antenna performance. For example, if the antenna of the electronic device 10 is arranged on the frame, different users have different holding postures. If the antenna is blocked by holding, it may cause serious deterioration of the antenna performance and eventually fail the WiFi wireless communication. After an antenna is held by the hand, the antenna performance may drop by 10 to 15 dB compared to the free space performance. At this time, if it is in a weak signal, it is likely to cause communication failure, seriously affecting the user experience.

鉴于上述技术问题,本申请实施例提供一种射频组件和电子设备,可支持WiFi无线通信,可以在不对输入功率进行回退的情况下,可以降低EIRP和SAR,使其满足响应的法规要求,同时,还可以避免电子设备中的各天线同时被握死的情况发生,可以提高射频组件和电子设备的上行链路的通信性能。In view of the above technical problems, the embodiments of the present application provide a radio frequency component and an electronic device that can support WiFi wireless communication. The EIRP and SAR can be reduced without backing off the input power to meet the corresponding regulatory requirements. At the same time, the situation in which the antennas in the electronic device are simultaneously held frozen can be avoided, thereby improving the uplink communication performance of the radio frequency component and the electronic device.

本申请提供一种射频组件。如图2和图3所示,本申请一个实施例中的射频组件100包括:无线保真模组110和至少一射频前端模组120。其中,无线保真模组110包括至少一第一射频端口和至少一第二射频端口,其中,第一射频端口和第二射频端口的数量可以相同,也可以不同。为了便于说明,在本申请实施例中,以第一射频端口和第二射频端口的数量相等(或,第一射频端口和第二射频端口成对设置)为例进行说明。其中,第一射频端口用于传输第一无线保真信号,第二射频端口用于传输第二无线保真信号。第一无线保真信号和第二无线保真信号的频段不同,例如,第一无线保真信号可以为Wi-Fi 2.4GHz信号,第二无线保真信号可以为Wi-Fi 5GHz信号,或者,第一无线保真信号可以为Wi-Fi5GHz信号,第二无线保真信号可以为Wi-Fi 2.4GHz信号。The present application provides a radio frequency component. As shown in Figures 2 and 3, the radio frequency component 100 in one embodiment of the present application includes: a wireless fidelity module 110 and at least one radio frequency front-end module 120. Among them, the wireless fidelity module 110 includes at least one first radio frequency port and at least one second radio frequency port, wherein the number of the first radio frequency port and the second radio frequency port may be the same or different. For ease of explanation, in the embodiment of the present application, the number of the first radio frequency port and the second radio frequency port is equal (or the first radio frequency port and the second radio frequency port are arranged in pairs) as an example for explanation. Among them, the first radio frequency port is used to transmit a first wireless fidelity signal, and the second radio frequency port is used to transmit 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, and the second wireless fidelity signal can be a Wi-Fi 5GHz signal, or the first wireless fidelity signal can be a Wi-Fi 5GHz signal, and the second wireless fidelity signal can be a Wi-Fi 2.4GHz signal.

可选的,无线保真模组110可以包括USB接口WiFi模块、以太网接口、UART接口串口WiFi模块、SDIO接口WiFi模块以及WCN模块中的至少一种。示例性的,无线保真模组110可以选用无线通信网络(Wireless Communication Network,WCN)模块,其中,WCN模块至少实现一种无线通信功能,例如Wi-Fi无线通信、蓝牙无线通信、FM(调频)无线通信、全球定位系统(Global Positioning System,GPS)无线通信等。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. Exemplarily, the wireless fidelity module 110 may use a wireless communication network (Wireless Communication Network, WCN) module, wherein 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, etc.

在本申请实施例中,射频前端模组120的数量与第一射频端口或第二射频端口的数量相同。各射频前端模组120的两个第一端分别与一第一射频端口、一第二射频端口对应连接,各射频前端模组120的两个第二端用于分别与两支天线对应连接。可以理解,射频前端模组120的数量、第一射频端口的数量、第二射频端口的数量分别相等。各射频前端模组的第一端连接的第一射频端口或第二射频端口各不相同。同一射频前端模组的各第二端连接的天线不同,且不同射频前端模组的各第二端连接的天线也不同。可以理解,电子设备10中包括的天线总数量为射频前端模组120总数量的二倍。In an embodiment of the present application, the number of RF front-end modules 120 is the same as the number of the first RF port or the second RF port. The two first ends of each RF front-end module 120 are respectively connected to a first RF port and a second RF port, and the two second ends of each RF front-end module 120 are used to be connected to two antennas respectively. It can be understood that the number of RF front-end modules 120, the number of first RF ports, and the number of second RF ports are respectively equal. The first RF port or the second RF port connected to the first end of each RF front-end module is different. The antennas connected to the second ends of the same RF front-end module are different, and the antennas connected to the second ends of different RF front-end modules are also different. It can be understood that the total number of antennas included in the electronic device 10 is twice the total number of RF front-end modules 120.

射频前端模组120用于对接收的第一无线保真信号和第二无线保真信号进行预处理以分别输出两路双频段信号至对应连接的两支天线。可以理解,各射频前端模组120可分别接收来自第一射频端口的第一无线保真信号,以及来自第二射频端口的第二无线保真信号,并对接收的第一无线保真信号和第二无线保真信号进行预处理,预处理后,射频前端模组120可输出两路双频段信号至对应连接的两支天线。其中,每一路双频段信号包括第一无线保真信号和第二无线保真信号,例如,双频段信号可包括WiFi 2.4G信号和WiFi 5G信号。其中,一路双频段信号输出至与射频前端模组120的一第二端连接的一天线,另一路双频段信号输出至与射频前端模组120的另一第二端连接的另一天线。预处理包括对接收到的第一无线保真信号、第二无线保真信号进行合路处理以及功分处理。在本申请实施例中,预处理中的合路处理和功分处理的前后顺序不做限定。The RF front-end module 120 is used to pre-process the received first wireless fidelity signal and the second wireless fidelity signal to output two dual-band signals to the corresponding two connected antennas. It can be understood that each RF front-end module 120 can receive the first wireless fidelity signal from the first RF port and the second wireless fidelity signal from the second RF port, respectively, and pre-process the received first wireless fidelity signal and the second wireless fidelity signal. After pre-processing, the RF front-end module 120 can output two dual-band signals to the corresponding two connected antennas. Among them, each dual-band signal includes a first wireless fidelity signal and a second wireless fidelity signal. For example, the dual-band signal may include a WiFi 2.4G signal and a WiFi 5G signal. Among them, one dual-band signal 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 the other second end of the RF front-end module 120. Pre-processing includes combining and power dividing the received first wireless fidelity signal and the second wireless fidelity signal. In the embodiment of the present application, the order of combining processing and power splitting processing in preprocessing is not limited.

在本申请实施例中,射频组件100包括无线保真模组110和至少一射频前端模组120,其中,射频前端模组120可对接收的第一无线保真信号和第二无线保真信号进行合路以及功分处理,以输出两路双频段信号。其中,射频前端模组120可对无线保真模组110提供的第一无线保真信号和第二无线保真信号进行功分功分处理可以降低双频段信号中的各无线保真信号的功率,进而可降低各个天线的发射功率,使得发射功率分布较为均匀,从而使得SAR和Peak EIRP降低,以符合安全相关法规要求。示例性的,经过预处理后,双频段信号中的第一无线保真信号的功率低于射频前端模组120接收的来自于无线保真模组110的第一无线保真信号的功率,双频段信号中的第二无线保真信号的功率低于射频前端模组120接收的来自于无线保真模组110的第二无线保真信号的功率。In the embodiment of the present application, the RF component 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 power-divide the received first wireless fidelity signal and the second wireless fidelity signal to output two dual-band signals. The RF front-end module 120 can power-divide the first wireless fidelity signal and the second wireless fidelity signal provided by the wireless fidelity module 110. The power-divide processing can reduce the power of each wireless fidelity signal in the dual-band signal, thereby reducing the transmission power of each antenna, so that the transmission power distribution is more uniform, thereby reducing SAR and Peak EIRP to meet the requirements of safety-related regulations.

可选地,本申请实施例中提供的天线可以为支持WiFi信号的接收和发射。本申请实施例中提供的天线也可以为柔性电路板(Flexible Printed Circuit,FPC)天线、激光直接成型(Laser Direct Structuring,LDS)天线、印刷直接成型(Print DirectStructuring,PDS)天线、辐射贴片和金属辐射枝节天线中的一种。在本申请实施例中,对天线的类型不做进一步的限定。在本申请实施例中,可以根据电子设备10的具体类型来选用合适的天线类型。Optionally, the antenna provided in the embodiment of the present application can be for supporting the reception and transmission of WiFi signals. The antenna provided in the embodiment of the present application can also be one of a flexible printed circuit (FPC) antenna, a laser direct structuring (LDS) antenna, a print direct structuring (PDS) antenna, a radiation patch, and a metal radiation branch antenna. In the embodiment of the present application, the type of antenna is not further limited. In the embodiment of the present application, a suitable antenna type can be selected according to the specific type of the electronic device 10.

本申请实施例中的电子设备10中通过设置射频组件100,可以射频前端模组120可对接收的第一无线保真信号和第二无线保真信号进行合路以及功分处理,以输出两路双频段信号,其中,双频段信号中的第一无线保真信号的功率低于射频前端模组120接收的来自于无线保真模组110的第一无线保真信号的功率,双频段信号中的第二无线保真信号的功率低于射频前端模组120接收的来自于无线保真模组110的第二无线保真信号的功率,这样,可以降低双频段信号中的各无线保真信号的功率,进而可降低各个天线的发射功率,使得发射功率分布较为均匀,从而使得SAR和Peak EIRP降低,以符合安全相关法规要求。另外,在射频前端模组120可输出两路双频段信号至对应连接的两支天线,即便是其中一支天线被遮挡,也能保证一路双频段信号可以正常传输至未被遮挡的天线,可以降低电子设备10被用户手持时,遮挡全部天线而使无线性能大幅降的机率,可以提高WiFi无线通信的通信性能。示例性的,若相关技术中电子设备10仅设置一支WiFi天线来支持WiFi双频段信号通信,而本申请实施例设置两支天线来支持WiFi双频段信号通信,在相同手握场景下(例如,分别遮挡一支天线)的对比如表3所示。In the electronic device 10 in the embodiment of the present application, by providing the RF component 100, the RF front-end module 120 can combine and power-divide the received first wireless fidelity signal and the second wireless fidelity signal to output two dual-band signals, wherein the power of the first wireless fidelity signal in the dual-band signal is lower than the power of the first wireless fidelity signal from the wireless fidelity module 110 received by the RF front-end module 120, 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 from the wireless fidelity module 110 received by the RF front-end module 120. In this way, the power of each wireless fidelity signal in the dual-band signal can be reduced, and then the transmission power of each antenna can be reduced, so that the transmission power distribution is more uniform, thereby reducing SAR and Peak EIRP to meet the requirements of safety-related regulations. In addition, the RF front-end module 120 can output two dual-band signals to the two correspondingly connected antennas. Even if one of the antennas is blocked, it can ensure that one dual-band signal can be normally transmitted to the unblocked antenna, which can reduce the probability of blocking all antennas and significantly reducing the wireless performance when the electronic device 10 is held by the user, and can improve the communication performance of WiFi wireless communication. For example, if the electronic device 10 in the related art is only equipped with one WiFi antenna to support WiFi dual-band signal communication, and the embodiment of the present application is equipped with two antennas to support WiFi dual-band signal communication, the comparison in the same hand-held scenario (for example, blocking one antenna respectively) is shown in Table 3.

表3为相关技术和本申请实施例手握场景影响的对比数据表Table 3 is a comparative data table of the impact of the hand-holding scene on the related technology and the embodiment of the present application

频段Frequency band 自由空间free space 相关技术手握场景Related technology hand-held scenarios 本申请实施例手握场景The present application embodiment holds the scene WiFi 2.4GWiFi 2.4G -5dB-5dB -20dB-20dB -10dB-10dB WiFi 5GWiFi 5G -6dB-6dB -17dB-17dB -9dB-9dB

由此可见,本申请实施例中提供的电子设备10,在正常握姿下,极大的降低了两支天线同时被握死的几率,手握影响在3~5dB左右,小于10~15dB的影响。显然,可以大幅度提升WiFi无线通信的通信性能。It can be seen that the electronic device 10 provided in the embodiment of the present application greatly reduces the probability of both antennas being held in a dead position at the same time in a normal grip, and the hand grip effect is about 3-5dB, which is less than the effect of 10-15dB. Obviously, the communication performance of WiFi wireless communication can be greatly improved.

在本申请实施例中,电子设备10包括射频组件100、第一天线ANT1和第二天线ANT2,其中,第一天线ANT1和第二天线ANT2分别设置在电子设备10相邻设置的两侧。第一天线ANT1和第二天线ANT2传输WiFi信号时产生的辐射方向图覆盖的空间不同。示例性的,电子设备10相邻设置的两侧可包括电子设备10的顶部所在侧,以及与顶部相邻的侧部所在侧。可选地,电子设备10相邻设置的两侧可包括电子设备10的底部所在侧,以及与底部相邻的侧部所在侧。In an embodiment of the present application, the electronic device 10 includes a radio frequency component 100, a first antenna ANT1 and a second antenna ANT2, wherein the first antenna ANT1 and the second antenna ANT2 are respectively arranged on two sides of the electronic device 10 that is adjacent to each other.

可选地,第一天线ANT1和第二天线ANT2分别设置在电子设备10相对设置的两侧,第一天线ANT1辐射方向图和第二天线ANT2的辐射方向图呈现互补特性。例如,第一天线ANT1可位于电子设备10的顶部所在侧,第二天线ANT2可位于电子设备10的底部所在侧。第一天线ANT1和第二天线ANT2传输WiFi信号时产生的辐射方向图覆盖的空间不同,第一天线ANT1和第二天线ANT2的辐射方向图可以互补,使得即使第一天线ANT1和第二天线ANT2的净空区域较小的情况下,电子设备10可以实现特定平面的全向特性。Optionally, the first antenna ANT1 and the second antenna ANT2 are respectively arranged on two sides of the electronic device 10 that are relatively arranged, and the radiation pattern of the first antenna ANT1 and the radiation pattern of the second antenna ANT2 present complementary characteristics. For example, the first antenna ANT1 may be located on the side where the top of the electronic device 10 is located, and the second antenna ANT2 may be located on the side where the bottom of the electronic device 10 is located. The radiation patterns generated by the first antenna ANT1 and the second antenna ANT2 when transmitting WiFi signals cover different spaces, and the radiation patterns of the first antenna ANT1 and the second antenna ANT2 can be complementary, so that even if the clearance area of the first antenna ANT1 and the second antenna ANT2 is small, the electronic device 10 can achieve omnidirectional characteristics in a specific plane.

No further details will be given here.

The first antenna ANT1 and the third antenna ANT3 are respectively arranged on two opposite sides of the electronic device 10, and the radiation pattern of the first antenna ANT1 and the radiation pattern of the third antenna ANT3 show complementary characteristics. The second antenna ANT2 and the fourth antenna ANT4 are respectively arranged on the other two opposite sides of the electronic device 10, and the radiation pattern of the second antenna ANT2 and the radiation pattern of the fourth antenna ANT4 show complementary characteristics.

在本申请实施例中,第一天线ANT1、第二天线ANT2、第三天线ANT3和第四天线ANT4分别布局在终端的不同侧边,让辐射方向图在各个角度上形成互补,使得方向图零点更少,大大减小同时失败的概率。具体地,图12为相关技术方案中双WiFi天线合成的辐射方向图,图13为本申请实施例中四WiFi天线合成的辐射方向图。其中,图2和图13为二维辐射方向图,其横坐标用于表征方向角Phi(φ),纵坐标用于表征方向角Theta(θ)。从两个图对比可以看出,图10合成的辐射方向图全向性比较差,最高方向和最低方向差别明显,而图11所示的辐射方向图在整个360°上分布都比较均匀。In an embodiment of the present 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 at various angles, so that there are fewer zero points in the pattern, and the probability of simultaneous failure is greatly reduced. Specifically, Figure 12 is a radiation pattern synthesized by two WiFi antennas in the related technical solution, and Figure 13 is a radiation pattern synthesized by four WiFi antennas in an embodiment of the present application. Among them, Figures 2 and 13 are two-dimensional radiation patterns, whose horizontal coordinates are used to characterize the direction angle Phi (φ), and the vertical coordinates are used to characterize the direction angle Theta (θ). From the comparison of the two figures, it can be seen that the omnidirectionality of the radiation pattern synthesized in Figure 10 is relatively poor, and the highest direction and the lowest direction are obviously different, while the radiation pattern shown in Figure 11 is relatively evenly distributed over the entire 360°.
