随着手机等电子设备的功能增加及内部器件数量增加，而人们对于手机的整机尺寸和重量有严格的要求，所以手机内部的空间极其有限。在手机极其有限的空间内需要布局4G低频天线、5G低频天线、4G高频天线、5G高频天线、GPS天线、Wi-Fi天线等。有些天线的数量需要配置多个。如此，使得手机内的空间极为紧张。而低频天线的尺寸相对较大，所以在手机内的低频天线的数量控制设置极其严格，以避免设置较多数量的低频天线之后，其他天线的位置不足。故本领域技术人员为了平衡高频天线、GPS天线、Wi-Fi天线的设置，对低频天线预留的空间较小，这就导致手机内可设置的低频天线的数量少，进而导致无法覆盖更多低频频段。现有手机边框上或附近设置天线的空间已用到极致，但是随着更多低频频段的开发和投入使用，手机将无法支撑较多低频频段，假如牺牲其他天线的空间必然带来其他的频段的信号差的问题，这样也会导致手机的体验差，因此，如何在手机有限的空间内实现更多低频段的覆盖，同时确保4G高频天线、5G高频天线、GPS天线、Wi-Fi天线等不会受到影响，甚至强度更强，成为需要解决的技术问题。
基于此，本申请实施例提供了一种能够在手机有限的空间内实现更多低频段的覆盖，同时确保4G高频信号、5G高频信号、GPS信号、Wi-Fi信号等不会受到影响，甚至信号强度更强的天线***及具有该天线***的电子设备。

由于传统技术的手机等电子设备中，由于手机内的空间有限，在一定的空间内预留给低频天线的空间有限，从而低频天线的数量受限，在低频天线的数量有限的情况下，手机支撑的低频频段有限，举例而言，假如手机内的极致空间内设置三个低频天线，其他天线设置空间已被其他天线占满，该三个低频天线仅仅能够支持低频中的K1频段和K2频段，其中，两个低频天线支持K1频段，由于K2频段的带宽相对较小(例如带宽小于60M)，可由一个低频天线支持。但是由于一个低频天线能够支持的带宽小于100M，所以一个低频天线将无法支持其他带宽相对较大的K3频段(例如带宽大于100M)和K4频段(例如带宽大于100M)，而随着低频段不断的被开发，K3频段和K4频段也投入使用，但现有手机无法支持带宽相对较大的K3频段和K4频段。

本申请的天线模块100a进行了设计，通过辐射体之间的耦合作用，以使辐射体可以相互复用，进而在确保收发低频信号和高频信号的同时，还能够尽可能的减小每个天线模块100a的辐射体的尺寸，从而在壳体上或内节省出部分的用于设置天线的空间，进而能够设置相对较多数量的低频天线。
请参阅图6及图7，具体的，第一天线模块110、第二天线模块120、第三天线模块130及第四天线模块140中的至少一者还包括至少一个中超高频天线单元600。中超高频天线单元600用于收 发频率大于1000MHz的电磁波信号。可选的，中超高频天线单元600可用于支持LTE中超高频频段。另可选的，中超高频天线单元600可用于支持NR中超高频频段。再可选的，中超高频天线单元600可通过开关电连接LTE中超高频收发芯片和NR中超高频收发芯片，以支持LTE中超高频频段、NR中超高频频段的任意一者。进一步地，中超高频天线单元600用于收发频段为1000MHz～10000MHz。具有低频天线单元和中超高频天线单元600的单个天线模块100a可同时覆盖4G、5G的所有低频段、中高频段、超高频段的电磁波信号，包括LTE-1/2/3/4/7/32/40/41，NR-1/3/7/40/41/77/78/79、Wi-Fi 2.4G、Wi-Fi 5G、GPS-L1、GPS-L5等，实现超宽带载波聚合(Carrier Aggregation，CA)及4G无线接入网与5G-NR的双连接(LTE NR Double Connect，ENDC)组合。
四个天线模块100a包括低频天线单元700和中超高频天线单元600的具体情形包括但不限于以下几种实施方式：第一种，四个天线模块100a中的一者包括低频天线单元700及至少一个中超高频天线单元600，另外三个天线模块100a皆包括低频天线单元700；第二种，四个天线模块100a中的两者皆包括低频天线单元700及至少一个中超高频天线单元600，另外两个天线模块100a皆包括低频天线单元700；第三种，四个天线模块100a中的三者皆包括低频天线单元700及至少一个中超高频天线单元600，另外一个天线模块100a包括低频天线单元700；第四种，四个天线模块100a皆包括低频天线单元700及至少一个中超高频天线单元600。

通过设置至少一个天线模块100a包括容性耦合的低频天线单元700和中超高频天线单元600，由于该低频天线单元700的辐射体与中超高频天线单元600的辐射体容性耦合，所以低频天线单元700的辐射体与中超高频天线单元600的辐射体实现相互复用，相较于非耦合状态的低频天线单元700和中超高频天线单元600，可有效地减小本申请提供的天线模块100a的辐射体的尺寸，进而使得天线模块100a在实现覆盖低频和中超高频的同时还具有较小的尺寸，进而节省出更多的空间以设置更多的低频天线单元700，如此，实现在电子设备1000内有限的空间能够设置至少四个低频天线单元700，以支持更多频段的低频信号，使得电子设备1000的通信质量更好而又不会增加电子设备1000的整机体积。

本申请对于第一天线单元10与第二天线单元20容性耦合产生的谐振模式不做具体的限定，以下通过实施方式对第一天线单元10与第二天线单元20容性耦合产生的谐振模式进行举例说明，但是第一天线单元10与第二天线单元20容性耦合产生的谐振模式包括但不限于以下的实施方式。
第一天线单元10用于产生多个谐振模式。而且，至少一个谐振模式由第一辐射体11与第二辐射体21容性耦合产生。
请参阅图9，第一天线单元10用于产生第一谐振模式a、第二谐振模式b、第三谐振模式c及第四谐振模式d。需要说明的是，第一天线单元10产生的谐振模式还包括除上述列举出来的谐振模式之外的其他模式，以上的四种谐振模式仅仅是相对效率较高的模式。
其中，请参阅图9，第二谐振模式b、第三谐振模式c的电磁波皆由第一辐射体11和第二辐射体21耦合产生。第一谐振模式a的频段、第二谐振模式b的频段、第三谐振模式c的频段及第四谐振模式d的频段分别对应第一子频段、第二子频段、第三子频段及第四子频段。在一实施方式中，第一子频段为1900～2000MHz之间；第二子频段为2600～2700MHz之间；第三子频段为3800～3900MHz之间；第四子频段为4700～4800MHz之间。换言之，第一天线单元10产生的电磁波信号位于中高频段(1000MHz-3000MHz)和超高频段内(3000MHz-10000MHz)。通过调节上述的谐振模式的谐振频点，可实现第一天线单元10对于中高频、超高频的全覆盖，及在所需频段得到较高的效率。
由上可知，当第一天线单元10不具有耦合天线单元时，第一天线单元10产生第一谐振模式a和第四谐振模式d。当第一天线单元10与第二天线单元20耦合时，第一天线单元10不仅仅产生第一谐振模式a、第四谐振模式d的电磁波模式，还产生第二谐振模式b、第三谐振模式c，如此，可知天线模块100a的带宽增加。
由于第一辐射体11及第二辐射体21间隔设置且相互耦合，也即，第一辐射体11及第二辐射体21共口径。当天线模块100a工作时，第一信号源12产生的第一激励信号可经由第一辐射体11耦合到第二辐射体21上。换而言之，第一天线单元10工作时不但可以利用第一辐射体11并且可以利用第二天线单元20中的第二辐射体21来收发电磁波信号，从而使得第一天线单元10可以工作在较宽的频段。同样地，第二辐射体21及第一辐射体11间隔设置且相互耦合，当天线模块100a工作时，第二信号源22产生的第二激励信号也可经由第二辐射体21耦合到第一辐射体11上，换而言之，第二天线单元20工作时不但可以利用第二辐射体21并且还可以利用第一天线单元10中的第一辐射体11来收发电磁波信号，从而使得第二天线单元20可工作在较宽的频段。由于第二天线单元20工作时不但可利用第二辐射体21并且可利用第一辐射体11，第一天线单元10工作时不但可利用第一辐射体11还可利用第二辐射体21，不仅提高了天线模块100a的辐射性能，还实现了辐射体的复用，也实现了空间的复用，有利于减小天线模块100a的尺寸，利于减小电子设备1000的整体体积。
通过设计第一天线单元10的第一辐射体11与第二天线单元20与第二辐射体21之间形成第一缝隙101，其中，第一天线单元10用于收发相对较高频段的电磁波信号，第二天线单元20用于收发相对较低频段的电磁波信号，一方面，使得天线模块100a工作时第一辐射体11与第二辐射体21能够容性耦合，以产生更多模式，提高天线模块100a的带宽，另一方面，第一天线单元10和第二 天线单元20的频段一中高一低，有效地提高第一天线单元10与第二天线单元20之间的隔离度，利于天线模块100a辐射所需频段的电磁波信号，由于第一天线单元10和第二天线单元20之间的辐射体实现了相互复用，实现多天线单元共体，所以天线模块100a在增加带宽的同时，还能够减小天线模块100a的器件堆叠空间，利于电子设备1000的整体小型化。
相关技术中需要较多的天线单元或者需要增加辐射体的长度，才能支持到第一谐振模式至第四谐振模式，从而导致天线模块的体积较大。本申请实施例中的天线模块100a中无需额外设置天线单元来支持第二谐振模式b、第三谐振模式c，因此，天线模块100a的体积较小。设置额外的天线支持第二谐振模式b以及设置额外的天线支持第三谐振模式c还可导致天线模块100a的成本较高；当天线模块100a应用于电子设备1000中时增加了天线模块100a与其他器件的堆叠难度。本申请实施例中天线模块100a不需要额外设置天线来支持第二谐振模式b、第三谐振模式c，因此，天线模块100a的成本较低；当天线模块100a应用于电子设备1000中堆叠难度较低。此外，设置额外的天线支持第二谐振模式b以及设置额外的天线支持第三谐振模式c还可导致天线模块100a的射频链路插损增加。本申请中天线模块100a可减少射频链路插损。

在一种可能的实施方式中，第一信号源12和第二信号源22可以为同一个信号源。该同一个信号源分别朝向第一选频滤波电路M1和第二选频滤波电路M2发射激励信号，第一选频滤波电路M1为阻低频通中高超高频的滤波电路。第二选频滤波电路M2为阻中高超高频通低频的滤波电路。所以激励信号的中高超高频部分经第一选频滤波电路M1流向第一辐射体11，使得第一辐射体11收发第一电磁波信号。激励信号的低频频部分经第二选频滤波电路M2流向第二辐射体21，以使第二辐射体21收发第二电磁波信号。
在另一种可能的实施方式中，第一信号源12和第二信号源22为不同的信号源。第一信号源12和第二信号源22可集成为一个芯片或单独封装的芯片。第一信号源12用于产生第一激励信号，第一激励信号经由第一选频滤波电路M1加载在第一辐射体11上，以使得第一辐射体11收发第一电磁波信号。第二信号源22用于产生第二激励信号，第二激励信号经由第二选频滤波电路M2加载在第二辐射体21上，以使得第二辐射体21收发第二电磁波信号。

请参阅图19，第三天线单元30产生的多个谐振模式至少包括第六谐振模式e、第七谐振模式f、第八谐振模式g及第九谐振模式h。需要说明的是，第三天线单元30产生的多个谐振模式还包括除上述列举出来的谐振模式之外的其他模式，以上的四种谐振模式仅仅是相对效率较高的模式。
其中，第七谐振模式f、第八谐振模式g皆由第三辐射体31和第二辐射体21耦合产生。第六谐振模式e的频段、第七谐振模式f的频段、第八谐振模式g的频段及第九谐振模式h的频段分别对应第五子频段、第六子频段、第七子频段及第八子频段。在一实施方式中，第五子频段为1900～2000MHz之间；第六子频段为2600～2700MHz之间；第七子频段为3800～3900MHz之间；第八子频段为4700～4800MHz之间。换言之，第三天线单元30产生的多个谐振模式位于中高频段(1000MHz-3000MHz)和超高频段内(3000MHz-10000MHz)。通过调节上述的谐振模式的谐振频点，可实现第三天线单元30对于中高频、超高频的全覆盖，及在所需频段得到较高的效率。
可选的，第三天线单元30的结构与第一天线单元10的结构相似。第三天线单元30、第二天线单元20之间的容性耦合作用与第一天线单元10、第二天线单元20之间的容性耦合作用相似。如此可知，当天线模块100a工作时，第三信号源32产生的第三激励信号可经由第三辐射体31耦合到第二辐射体21上。换而言之，第三天线单元30工作时不但可以利用第三辐射体31并且可以利用第二天线单元20中的第二辐射体21来收发电磁波信号，从而使得第三天线单元30在不额外增设辐射体的基础上增加其工作带宽。
由于第一天线单元10、第二天线单元20及第三天线单元30分别为收发中高超高频、低频、中高超高频，如此，第一天线单元10与第二天线单元20之间、第二天线单元20与第三天线单元30之间通过频段隔离，以避免相互之间的信号干扰，第一天线单元10与第三天线单元30之间通过物理间距隔离，以避免相互之间的信号干扰，以便于控制天线模块100a收发所需频段的电磁波信号。

本申请实施例中，以第一耦合点C`为靠近第二耦合端H2为例进行举例说明，当然，以下第一耦合点C`的设置也适用于靠近第三耦合端H3的情况。
第一耦合点C`用于接地，如此，第一信号源12发射的第一激励信号经第一选频滤波电路M1的滤波后从第一馈电点A传送至第一辐射体11，激励信号在第一辐射体11上具有不同的作用方式，例如，第一激励信号从第一馈电点A朝向第一接地端G1作用，并在第一接地端G1入参考地极40，形成一条天线回路；第一激励信号从第一馈电点A朝向第一耦合端H1作用，经第一缝隙101耦合至第二耦合端H2与第一耦合点C`，并从第一耦合点C`入参考地极40，形成另一条耦合的天线回路。

例如，第一谐振模式a对应的谐振频点位于1900～2000MHz之间。当电子设备1000需要收发1900～2000MHz之间的电磁波信号时，调节第一调频电路T1的调频参数(例如电阻值、电容值、电感值)，以使第一天线单元10工作在第一谐振模式a。当电子设备1000需要收发1800～1900MHz之间的电磁波信号时，进一步调节第一调频电路T1的调频参数(例如电阻值、电容值、电感值)，以使第一谐振模式a的谐振频点朝向低频段偏移。当电子设备1000需要收发2000～2100MHz之间的电磁波信号时，进一步调节第一调频电路T1的调频参数(例如电阻值、电容值、电感值)，以使第一谐振模式a的谐振频点朝向高频段偏移。如此，通过调节第一调频电路T1的调频参数可实现第一天线单元10在较宽频段的频率覆盖。

可选的，第二馈电点C为第一耦合点C`。第二选频滤波电路M2可对第三谐振模式c的频点进行调节。将第一耦合点C`作为第二馈电点C，以使得第一耦合点C`既可以作为第二天线单元20的 馈电还可以作为与第一天线单元10的耦合天线单元，增加了天线的结构紧凑性。当然，在其他实施方式中，第二馈电点C可设于第一耦合点C`与第三耦合端H3之间。
第二信号源22产生的第二激励信号经第二选频滤波电路M2滤波和调节之后作用于第一调频点B与第三耦合端H3之间，以产生第五谐振模式。
进一步地，请参阅图8及图21，第二辐射体21还包括第二调频点D。第二调频点D位于第二馈电点C与第三耦合端H3之间。第二天线单元20还包括第三调频电路T3。在一实施方式中，第三调频电路T3用于口径调节，具体的，第三调频电路T3的一端电连接第二调频点D，第三调频电路T3的另一端接地。第三调频电路T3通过调节第一调频点B与第三耦合端H3之间的阻抗，用于调节第五谐振模式的谐振频点。
其中，第一调频点B与第三耦合端H3之间的长度可以约为第二频段的电磁波的波长的四分之一，以使第二天线单元20具有较高的辐射效率。
此外，第一调频点B接地、第一耦合点C`为第二馈电点C，以使第二天线单元20为倒F天线，该天线形式，通过调节第二馈电点C的位置可以方便地调节第二天线单元20的阻抗匹配。
在一实施方式中，第三调频电路T3包括但不限于串联和/或并联设置的电容、电感、电阻等，第三调频电路T3可包括多个串联和/或并联的电容、电感、电阻形成的支路，及控制多个支路的通断的开关。通过控制不同开关的通断，可以调节第三调频电路T3的选频参数(包括电阻值、电感值及电容值)，进而对于第一调频点B与第三耦合端H3之间的部分第二辐射体21的阻抗进行调节，进而使第二天线单元20收发第五谐振模式的谐振频点或附近谐振频点的电磁波信号。

第二调频点D的位置为上述的第一耦合点C`靠近第三耦合端H3时所在的位置。所以，第二调频点D与第三耦合端H3之间形成第二耦合段R2。第二耦合段R2与第三辐射体31通过第二缝隙102进行耦合。
由上述可知，通过设置调频电路及调频电路的参数进行调节，可使第一天线单元10在中高频段、超高频段进行全覆盖，使第二天线单元20在低频段进行全覆盖，使第三天线单元30在中高频段、超高频段进行全覆盖，如此，实现了天线模块100a在低频段、中高频段及超高频段之间进行全覆盖，实现通信功能增强；天线单元之间的辐射体复用，可使得天线模块100a的整体尺寸较小，促进整机的小型化。
可选的，第三天线单元30的结构与第一天线单元10的结构相似。
请参阅图8及图22，图22为第三天线单元30的等效电路图。第三天线单元30、第二天线单元20之间的容性耦合作用与第一天线单元10、第二天线单元20之间的容性耦合作用相似。如此可知，当天线模块100a工作时，第三信号源32产生的第三激励信号可经由第三辐射体31耦合到第二辐射体21上。换而言之，第三天线单元30工作时不但可以利用第三辐射体31并且可以利用第二天线单元20中的第二辐射体21来收发电磁波信号，从而使得第三天线单元30在不额外增设辐射体的基础上增加其工作频宽。
第六谐振模式e、第七谐振模式f、第八谐振模式g及第九谐振模式h的谐振频点的调节可参考第一谐振模式a、第二谐振模式b、第三谐振模式c及第四谐振模式d的调节方式，在此不再赘述。
天线模块100a的多模式同时工作可实现超带宽实现超宽带载波聚合(Carrier Aggregation，CA)及4G无线接入网与5G-NR的双连接(LTE NR Double Connect，ENDC)组合。
由于第一天线单元10、第二天线单元20及第三天线单元30分别为收发中高超高频、低频、中高超高频，如此，第一天线单元10与第二天线单元20之间、第二天线单元20与第三天线单元30之间通过频段隔离，以避免相互之间的信号干扰，第一天线单元10与第三天线单元30之间通过物理间距隔离，以避免相互之间的信号干扰，以便于控制天线模块100a收发所需频段的电磁波信号。
此外，第一天线单元10和第三天线单元30可以设于电子设备1000上的不同的方位或位置，以便于在不同的场景下进行切换，例如，在电子设备1000在横屏与竖屏之间切换时可切换第一天线单元10和第三天线单元30，或者，第一天线单元10被遮挡时切换至第三天线单元30，在第三天线单元30被遮挡时切换至第一天线单元10，以在不同的场景下皆可以具有较好的中高超高频的电磁波的收发。
