请参阅图2，并结合图1所示，图2是图1所示的电子设备的分解示意图。电子设备100包括壳体10、屏幕20及电路板30。
其中，壳体10可用于支撑屏幕20以及电子设备100内相关器件。
一种实施方式中，壳体10包括后盖11及边框12。后盖11与屏幕20相对设置。后盖11与屏幕20安装于边框12的相背两侧，此时，后盖11、边框12与屏幕20共同围设出收容空间13。收容空间13可用于收容电子设备100的器件，例如电池、扬声器、麦克风或者听筒。结合附图1所示，附图1示意了后盖11、边框12与屏幕20围成大致呈长方体的结构。
一种实施方式中，后盖11可通过粘胶固定连接于边框12上。在另一种实施方式中，后盖11也可以与边框12形成一体结构，即后盖11与边框12一体成型。
其中，后盖11的材质可以是金属材料，也可以是绝缘材料，例如玻璃或者塑料等。此外，边框12的材质可以为金属材料，也可以为绝缘材料，例如塑料或者玻璃等。
其中，屏幕20安装于壳体10。屏幕20可用于显示图像、文字等。
一种实施方式中，屏幕20包括保护盖板21和显示屏22。保护盖板21层叠于显示屏22。保护盖板21可以紧贴显示屏22设置，可主要用于对显示屏22起到保护防尘作用。保护盖板21的材质可以为但不仅限于为玻璃。显示屏22可以采用有机发光二极管(organic light-emitting diode，OLED)显示屏，有源矩阵有机发光二极体或主动矩阵有机发光二极体(active-matrix organic light-emitting diode，AMOLED)显示屏，迷你发光二极管(mini organic light-emitting diode)显示屏，微型发光二极管(micro organic light-emitting diode)显示屏，微型有机发光二极管(micro organic light-emitting diode)显示屏，量子点发光二极管(quantum dot light emitting diodes，QLED)显示屏。
其中，电路板30可用于安装电子设备100的电子元器件。例如，电子元器件可以包括中央处理器(central processing unit，CPU)、电池管理单元和基带处理单元。电路板30位于屏幕20与后盖11之间，也即电路板30位于收容空间13内。电路板30在电子设备100内的位置不仅限于附图1虚线所示意的位置。
此外，电路板30可以为硬质电路板，也可以为柔性电路板，也可以为软硬结合电路板。此外，电路板30可以采用FR-4介质板，也可以采用罗杰斯(Rogers)介质板，也可以采用Rogers和FR-4的混合介质板，等等。这里，FR-4是一种耐燃材料等级的代号，Rogers 介质板为一种高频板。
此外，电子设备100包括多个天线。在本申请中，“多个”是指至少两个。天线用于发射和接收电磁波信号。电子设备100中的每个天线可用于覆盖单个或多个通信频带。不同的天线还可以复用，以提高天线的利用率。
电子设备100可以通过天线，以利用以下一种或多种通信技术与网络或其他设备通信。其中，通信技术包括蓝牙(bluetooth，BT)通信技术、全球定位系统(global positioning system，GPS)通信技术、无线保真(wirelessfidelity，Wi-Fi)通信技术、全球移动通讯系统(global system for mobile communications，GSM)通信技术、宽频码分多址(wideband code division multiple access，WCDMA)通信技术、长期演进(long term evolution，LTE)通信技术、5G通信技术、SUB-6G通信技术以及未来其他通信技术等。

可以理解的是，图1及图2仅示意性的示出了电子设备100包括的一些部件，这些部件的实际形状、实际大小和实际构造不受图1及图2限定。
此外，为了给用户带来更为舒适的视觉感受，电子设备100可以采用全面屏工业设计(industry design，ID)。全面屏意味着极大的屏占比(通常在90％以上)。全面屏的边框12宽度大幅缩减，需要对电子设备100内部器件，如前置摄像头、受话器、指纹识别器、天线等，进行重新布局。尤其对于天线设计来说，净空区域缩减，天线空间进一步被压缩。而天线的尺寸、带宽、效率是相互关联、相互影响的，减小天线尺寸(空间)，天线的效率带宽积(efficiency-bandwidth product)势必减小。
在传统的天线设计中，在天线设计空间进一步缩减的情况下，在金属边框、玻璃后盖这种常见ID的手机上，往往在整机四周布局多个不同的辐射体来实现多输入多输出(multi-input multi-output，MIMO)天线。但是，这多个不同的辐射体需要在天线形式、接地、馈电等方面符合较高要求，才能实现较高的天线隔离度以及较低的包络相关系数(envelopeIcorrelation coefficient，ECC)。
本申请提供的天线设计方案可应用于MIMO天线中。通过设置一种天线结构，以及利用两种馈电方式：对称馈电和反对称馈电，可实现高隔离度、低ECC的MIMO天线特性。此外，天线结构还能实现覆盖较多频段的天线，从而使得具有有限空间的电子设备100也可以发射或者接收较多频段的电磁波信号。
首先，介绍本申请涉及四个天线模式。
1.共模(common mode，CM)槽天线模式
如图3A所示，图3A为本申请涉及的共模槽天线的示意图。槽天线101可包括：缝隙103、馈电点107以及馈电点109。其中，缝隙103可开设在PCB17的地板上。缝隙103的一侧设有开口105，开口105可具体开设在该侧的中间位置。馈电点107以及馈电点109可分别设置在开口105的两侧。馈电点107、馈电点109可分别用于连接槽天线101的馈源的正极、负极。例如，采用同轴传输线对槽天线101进行馈电，同轴传输线的中心导体 (transmission line center conductor)可通过传输线连接至馈电点107，同轴传输线的外导体(transmission line outer conductor)可通过传输线连接至馈电点109。同轴传输线的外导体是接地的。
也即是说，槽天线101可在开口105处馈电，开口105又可以称为馈电处。馈源的正极可连接在开口105的一侧，馈源的负极可连接在开口105的另一侧。
如图3B所示，图3B为共模槽天线模式的电流、电场、磁流的分布的示意图。电流在槽天线101的中间位置两侧呈现同向分布，但电场、磁流在槽天线101的中间位置两侧呈现反向分布。图3A中示出的这种馈电结构可以称为反对称馈电结构。图3B所示的这种槽天线模式可以称为CM槽天线模式。图3B所示的电场、电流、磁流可分别称为CM槽天线模式的电场、电流、磁流。
CM槽天线模式的电流、电场是槽天线101的中间位置两侧的槽各自工作在1/4波长模式产生的：电流在槽天线101的中间位置处弱，在槽天线101的两端强。电场在槽天线101的中间位置处强，在槽天线101的两端弱。
2.差模(differential mode，DM)槽天线模式
如图4A所示，图4A为本申请涉及的差模槽天线的示意图。槽天线110可包括：缝隙113、馈电点117以及馈电点115。其中，缝隙113可开设在PCB17的地板上。馈电点117、馈电点115可分别设置在缝隙113的两个侧边的中间位置。馈电点117、馈电点115可分别用于连接槽天线110的馈源的正极、负极。例如，采用同轴传输线对槽天线110进行馈电，同轴传输线的中心导体可通过传输线连接至馈电点117，同轴传输线的外导体可通过传输线连接至馈电点115。同轴传输线的外导体是接地的。
也即是说，槽天线110的中间位置112处连接馈源，中间位置112又可以称为馈电处。馈源的正极可连接缝隙113的一侧边，馈源的负极可连接缝隙113的另一侧边。
如图4B所示，图4B为差模槽天线模式的电流、电场、磁流的分布的示意图。电流在槽天线110的中间位置112两侧呈现反向分布，但电场、磁流在槽天线110的中间位置112两侧呈现同向分布。图4A中示出的这种馈电结构可以称为对称馈电结构。图4B所示的这种槽天线模式可以称为DM槽天线模式。图4B所示的电场、电流、磁流可分布称为DM槽天线模式的电场、电流、磁流。
DM槽天线模式的电流、电场是整个缝隙113工作在1/2波长模式产生：电流在槽天线110的中间位置处弱，在槽天线110的两端强。电场在槽天线110的中间位置处强，在槽天线110的两端弱。
3.共模(common mode，CM)线天线模式

CM线天线模式的电流、电场是线天线101在中间位置103两侧的两个水平枝节作为1/4波长天线产生的。电流在线天线101的中间位置103处强，在线天线101的两端弱。电场在线天线101的中间位置103处弱，在线天线101的两端强。
4.差模(differential mode，DM)线天线模式

DM线天线模式的电流、电场是整个线天线104作为1/2波长天线产生的。电流在线天线104的中间位置106处强，在线天线104的两端弱。电场在线天线104的中间位置106处弱，在线天线104的两端强。
第一种实施例：通过设置一种槽天线和线天线组成的天线结构，并利用两种馈电方式，以使天线结构激励出四种天线模式：共模槽天线、差模槽天线、共模线天线及差模线天线。这样，本实施例可通过两种馈电方式，以使槽天线和线天线组成的天线结构激励出多种谐振模式，从而实现天线可覆盖多个频段。
请参阅图7，图7是图1所示电子设备在A-A线处的剖面示意图。边框12包括相对设置的第一长边框121以及第二长边框122与相对设置的第一短边框123以及第二短边框124。第一短边框123与第二短边框124连接在第一长边框121与第二长边框122之间。此时，边框12的形状呈矩形，或者大致呈矩形。电路板30位于第一长边框121、第二长边框122、第一短边框123以及第二短边框124所围成的区域内。在本实施例中，天线结构的辐射体是第一短边框123的一部分为例进行说明。在其他实施例中，天线结构的辐射体也可以是第一长边框121的一部分、第二长边框122的一部分或者第二短边框124的一部分。当然，在其他实施例中，第一长边框121的一部分、第二长边框122的一部分、第一短边框123的一部分以及第二短边框124的一部分中的两个或者两个以上均可以作为天线结构的辐射体。
请参阅图8，图8是图7所示的电子设备在B处的一种实施方式的放大示意图。
首先，结合相关附图具体描述一下槽天线的辐射体的结构以及线天线的辐射体的结构。
在第一方向上(附图8示意了第一方向为X方向，在其他实施方式中，第一方向也可以为Y方向)，第一短边框123包括依次连接的第一金属段的1231、第一绝缘段1232和第二金属段1233，也即第一绝缘段1232连接在第一金属段1231与第二金属段1233之间。此时，第一绝缘段1232将第一金属段1231与第二金属段1233电隔离。可以理解的是，第一金属段1231与第二金属段1233之间形成第三缝隙。第一绝缘段1232可以通过在第三缝隙内填充绝缘材料所形成，例如绝缘材料可以为聚合物、玻璃、陶瓷等材料或者这些材料的组合。在其他实施例中，第三缝隙内可填充空气，也即第三缝隙未填充任何绝缘材料。
在其他实施例中，第三缝隙内也可以设置有至少一个悬浮金属段。此时，第三缝隙内被悬浮金属段分成多个部分。
在其他实施例中，第一金属段的1231与第二金属段1233的位置可以对调。此时，第一金属段的1231位于第一绝缘段1232的右边。第二金属段1233位于第一绝缘段1232的左边。
第一金属段的1231包括依次连接的第一部分1、第一接地部分2及第二部分3。换言之，第一接地部分2连接在第一部分1与第二部分3之间。第一接地部分2指的是第一金属段的1231中接地的部分。第一接地部分2的大小及形状不局限于附图8所示意的大小及形状。
可以理解的是，第一接地部分2接地的方式具有多种。一种实施方式中，边框12包括连接枝节125。连接枝节125的材质为导电材料，例如金属材料。此时，第一接地部分2通过连接枝节125电连接于电路板30的地板。连接枝节125可以与第一金属段1231为一体成型结构。当然，连接枝节125也可以通过焊接或者粘接固定于第一金属段1231。在其他实施方式中，电子设备100也可以包括弹片。第一接地部分2通过弹片电连接于电路板30的地板。
此外，第一金属段1231与电路板30之间设置有第一缝隙31。第一缝隙31连通第一金属段1231与第二金属段1233之间形成第三缝隙。一种实施方式中，第一缝隙31内可填充绝缘材料，例如第一缝隙31内可填充聚合物、玻璃、陶瓷等材料或者这些材料的组合。另一种实施方式中，第一缝隙31内可填充空气，也即第一缝隙31未填充任何绝缘材料。

请参阅图9，并结合图8所示，图9是图8所示的电子设备的天线结构的一种实施方式的示意图。第一部分1与第一接地部分2形成第一辐射体101。第二部分3与第一接地部分2形成第二辐射体102。此时，第一接地部分2为第一辐射体101与第二辐射体102的接地端。第一辐射体101远离第一接地部分2的端部为未接地的开放端。第二辐射体102远离第一接地部分2的端部为未接地的开放端。
此外，第三部分4与第二接地部分5形成第三辐射体103。第四部分6与第二接地部分5形成第四辐射体104。此时，第二接地部分5为第三辐射体103与第四辐射体104的接地端，第三辐射体103远离第二接地部分5的端部为未接地的开放端。第四辐射体104远离第二接地部分5的端部为未接地的开放端。
这样，第二辐射体102与第三辐射体103形成槽天线40的辐射体。第一辐射体101与第四辐射体104形成线天线50的辐射体。
在本实施例中，第二辐射体102的长度与第三辐射体103的长度相等，且第二辐射体 102的长度与第三辐射体103的长度均为1/4波长。波长可依据第第二辐射体102与第三辐射体103的工作频率f1计算得到。具体的，辐射信号在空气中的波长可以如下计算：波长＝光速/f1。辐射信号在介质中的波长可以如下计算：波长＝(光速/√ε)/f1，其中，ε为该介质的相对介电常数。此时，槽天线40的辐射体的对称性较佳。可以理解的是，实际应用中，第二辐射体102的长度与第三辐射体103的长度难以完全相等，可以通过调整匹配电路等来补偿这种结构上的不平衡。
第一辐射体101的长度与第四辐射体104的长度相等，且第一辐射体101的长度与第四辐射体104的长度为1/4波长。波长可依据第一辐射体101与第四辐射体104的工作频率f1计算得到。具体的，辐射信号在空气中的波长可以如下计算：波长＝光速/f1。辐射信号在介质中的波长可以如下计算：波长＝(光速/√ε)/f1，其中，ε为该介质的相对介电常数。此时，线天线50的辐射体较佳。可以理解的是，实际应用中，第一辐射体101的长度与第四辐射体104的长度难以完全相等，可以通过调整匹配电路等来补偿这种结构上的不平衡。
在其他实施例中，第二辐射体102的长度与第三辐射体103的长度也可以不相等。第一辐射体101的长度与第四辐射体104的长度也可以不相等。

在本实施例中，桥结构41设置于电路板30，且桥结构41与电路板30的地板绝缘设置。一种实施方式中，电路板30朝屏幕20的表面为地板。此时，在电路板30背离屏幕20的表面设置桥结构41。这样，桥结构41能够与电路板30的地板绝缘设置。桥结构41的结构形式可以是柔性电路板、激光直接成型(laser direct structuring，LDS)金属、模内注塑金属或印刷电路板的走线。再一种实施方式中，在电路板30朝屏幕20的表面设置支架。支架的材质为绝缘材料，例如塑料。此时，支架与电路板30的地板绝缘设置。再将桥结构41设置于支架上。这样，桥结构41也能够与电路板30的地板绝缘设置。
在本实施例中，桥结构41为对称图形。例如，桥结构41的形状为“П”形。此时，桥结构41的对称性较佳，也即槽天线40的对称性较佳。桥结构41的结构较为简单，易于制备。在其他实施方式中，桥结构41的形状也可以为弧形。此外，桥结构41也可以为非对称图形。
此外，桥结构41的一端连接于第二辐射体102。一种实施方式中，桥结构41的一端通过弹片连接于的第二辐射体102。桥结构41的另一端连接于第三辐射体103。一种实施方式中，桥结构41的另一端通过弹片连接于第三辐射体103。此时，第二辐射体102连接桥结构41的位置为槽天线40的第一个馈电点。第三辐射体103连接桥结构41的位置为槽天线40的第二个馈电点。
请再次参阅图8及图9，槽天线40还包括第一馈电电路42。第一馈电电路42的负极接地，也即第一馈电电路42的负极电连接于电路板30的地板。第一馈电电路42的正极电连接于桥结构41的中部。附图8通过箭头简单地示意了第一馈电电路42的正极和负极的朝向。箭头的指向为负极指向正极。可以理解的是，该种馈电方式为对称馈电方式。

以下结合图21g至图21l来具体描述一下天线结构在五个谐振频率下的辐射方向示意图。图21g是图17所示的天线结构在频率为1.75GHz的信号下的辐射方向的示意图。图21h是图17所示的天线结构在频率为2.36GHz的信号下的辐射方向的示意图。图21i是图17所示的天线结构在频率为2.79GHz的信号下的辐射方向的示意图。图21j是图17所示的天线结构在频率为1.87GHz的信号下的辐射方向的示意图。图21k是图17所示的天线结构在频率为2.36GHz的信号下的辐射方向的示意图。图21l是图17所示的天线结构在频率 为2.87GHz的信号下的辐射方向的示意图。
请参阅图21g至图21i，图21g至图21i的天线结构在反对称馈电下，产生的天线信号的辐射方向在Y轴方向的辐射强度较强,在X轴方向的辐射强度较弱，也即频率为1.75GHz的共模槽天线在Y轴方向的辐射强度较强、频率为2.36GHz的共模槽天线在Y轴方向的辐射强度较强、2.79GHz的差模线天线在Y轴方向的辐射强度较强。
请参阅图21j至图21l，图21j至图21l的天线结构在反对称馈电下，产生的天线信号的辐射方向在X轴方向的辐射强度较强,在Y轴方向的辐射强度较弱，也即频率为1.87GHz的差模槽天线在X轴方向的辐射强度较强、频率为2.36GHz的共模线天线在X轴方向的辐射强度较强、2.87GHz的共模线天线在X轴方向的辐射强度较强。
此外，根据图13f至图13j可知，在相同的频段(例如本实施方式的0-3GHz)下，天线结构在反对称馈电方式下，产生的激励谐振信号以及天线结构在对称馈电方式下，产生的激励谐振信号的方向差异较大。此时，天线结构辐射范围较广。
此外，通过图21g至图21l的两个天线的辐射方向图可以计算出在反对称馈电下，产生的天线信号与在对称馈电下，产生的天线信号的ECC均小于0.1。换言之，本实施例的天线结构的ECC较小。
在本实施例中，通过设置一种槽天线40和线天线50组成的天线结构，并利用两种馈电方式，以使天线结构激励出六个谐振模式，也即产生六个谐振频率，从而实现天线覆盖多个频段。
此外，天线结构在反对称馈电方式下，产生的激励谐振信号以及天线结构在对称馈电方式下，产生的激励谐振信号，两者之间的隔离度可以达到22dB以上，从而使得天线结构的天线性能更佳。
