如图1和图2所示，本申请实施例提供一种天线装置。天线装置包括第一天线组件110和第二天线组件120。其中，第一天线组件110包括第一馈源S1、第三馈源S3以及设有第一馈电点A、第三馈电点C的第一辐射体111。在本申请实施例中，第一馈电点A和第三馈电点C可以为同一馈电点，也可以为不同的馈电点。示例性的，当第一馈电点A 与第三馈电点C不共用时，第一馈电点A相对于第三馈电点C靠近缝隙101设置。
第二天线组件120，包括第二馈源S2以及设有第二馈电点B的第二辐射体121，第一辐射体111与第二辐射体121之间设有缝隙101。该缝隙101可以作为第一辐射体111和第二辐射体121的耦合缝隙101，用于实现两个辐射体之间的容性耦合。第一馈源S1、第二馈源S2、第三馈源S3可以为产生馈电信号(或激励信号)的器件。在本申请实施例中，第一馈源S1用于产生第一馈电信号，第二馈源S2用于产生第二馈电信号，第三馈源S3用于产生第三馈电信号。其中，第一馈电信号、第二馈电信号、第三馈电信号不同。

在本申请实施例中，需要说明的是，第一辐射体支持第一频段可以理解为，第一辐射体接收第一频段的射频信号，或第一辐射体发射第一频段的射频信号，或第一辐射体接收和发射第一频段的射频信号。
第一辐射体111、第二辐射体121可分别为柔性电路板(Flexible Printed Circuit，FPC)天线辐射体、激光直接成型(Laser Direct Structuring，LDS)天线辐射体、印刷直接成型(Print Direct Structuring，PDS)天线辐射体、金属辐射枝节中的一种。在本申请实施例中，对第一辐射体111、第二辐射体121的辐射体类型不做进一步的限定，且第一辐射体111和第二辐射体121的类型可以相同，也可以不同。在本申请实施例中，为了便于说明，以第一辐射体111、第二辐射体121为金属辐射枝节，例如电子设备的导电边框为例进行说明。需要说明的是，第一辐射体111与第二辐射体121之间的缝隙101的宽度可以根据实际情况而定，其需要满足第一辐射体111与第二辐射体121可以耦合的最小尺寸。
第一频段、第二频段、第三频段各不相同，示例性的，第一频段所覆盖的频率范围、第二频段所覆盖的频率范围、第三频段所覆盖的频率范围各不同。在本实施实施例中，第一频段为超高频(Ultra High Band，UHB)频段，第二频段为中高频(Middle High Band，MHB)频段。需要说明的是，UHB频段的频段范围在3000MHz-6000MHz，示例性的，可以包括5G新空口(New Radio，NR)信号，示例性的，可以包括NR-77/78/79等频段的射频信号。MHB频段范围在1000MHz-3000MHz。其中，MHB的射频信号可以包括4G长期演进(Long Term Evolution，LTE)与5G NR的部分或所有中高频频段的射频信号，示例性的，可以包括LTE-1/2/3/4/7/32/34/38/39/40/41频段的信号以及NR-1/3/7/40/41等频段的射频信号。第三频段为低频(Lower Band，LB)频段，LB频段的范围为低于1000MHz。其中，低频频段的射频信号可以包括4G-LTE与5G-NR的部分或所有低频段的射频信号。
本申请实施例中，天线装置包括第一天线组件110和第二天线组件120，其中，第一 天线组件110和第二天线组件120通过设置独立的馈源，以将不同的馈电信号分别馈入至不同的辐射体，以支持对第一频段和第二频段的射频信号的收发，相比于相关技术中，需要在第一馈源S1和第二馈源S2与馈电点之间增加合路器，以将不同的馈电信号经过合路处理后加载在同一馈电点的方式，可以避免使用合路器，进而可以降低第一频段和第二频段的射频信号的收发链路上合路器带来的链路插损，以提高对第一频段和第二频段的射频信号的收发性能，同时降低成本。
进一步的，第一天线组件110可以支持对超高频和低频的射频信号的收发，例如，不需要设置额外的辐射体(除第一辐射体、第二辐射体以外的辐射体)来支持对第三频段的射频信号的收发，可以通过复用第一辐射体的方式来实现对第一频段和第三频段的射频信号的收发，减少天线装置的占用空间，还可以降低成本。第二天线组件120可以支持对中高频的射频信号的收发处理，可以利用较少的天线辐射体实现较宽频段的覆盖，同时也可以实现低频、中高频以及超高频的载波聚合(Carrier Aggregation，CA)例如，全频段的覆盖，以及4G-LTE信号与5G-NR的双连接(LTE NR Double Connect，ENDC)组合，可以进一步提高天线装置的通信性能。
如图3所示，本申请实施例还提供一种天线装置。天线装置包括第一天线组件110，其中，第一天线组件110包括：第一馈源S1、第三馈源S3以及第一辐射体110。第一辐射体110上设有第一馈电点A，分别与第一馈源A、第三馈源C连接。第一馈源S1通过第一馈电点A向第一辐射体110馈入第一馈电信号，以使部分第一辐射体110支持第一频段。第三馈源S3用于通过第一馈电点A向第一辐射体110馈入第三馈电信号，以使第一辐射体110支持第三频段，其中，第一频段、第三频段各不相同。
本申请实施例中，天线装置包括第一天线组件，其中，第一天线组件包括第一馈源、第三馈源和第一辐射体，其中，第一辐射体设有第一馈电点，第一馈源和第三馈源提供的馈电信号可以共用第一馈电点，以使第一辐射体既可以支持对第一频段，也可以支持第三频段。相关技术中，每个馈源需要独立设置一个馈电点、不同馈电点设置在不同辐射体上。本申请实施例中，也不需要设置额外的馈电点(除第一馈电点以外的馈电点)和辐射体(除第一辐射体以外的辐射体)可以采用共用馈电点，共用辐射体的方式来实现对第一频段和第三频段的射频信号的收发，可以降低成本，减少天线装置的占用空间(例如，可以节约弹片组件等)，有利于天线装置的小型化设置。
请继续参考图3，在其中一个实施例中，第一馈电点A和第三馈电点C为同一馈电点。可以理解的，第一馈源S1输出的第一馈电信号，以及第三馈源S3输出的第三馈电信号都可以加载在第一馈电点A上，以通过第一馈电点A向第一辐射体111加载相应的馈电信号。在本申请实施例中，第一馈源S1提供的第一馈电信号与第三馈源S3提供的第三馈电信号的频率范围相差较大，因此第一馈电信号与第三馈电信号之间彼此之间相互干扰的影响较小，即便是第一辐射体111同时支持对第一频段、第三频段的射频信号的收发，也不会影响其收发性能。
在本申请实施例中，第一馈源S1和第三馈源S3提供的馈电信号可以共用同一个馈电点，如第一馈电点A，以使第一辐射体111既可以支持对第一频段，也可以支持第三频段。相关技术中，每个馈源需要独立设置一个馈电点、不同馈电点设置在不同辐射体的方式。本申请实施例中，也不需要设置额外的馈电点(除第一馈电点A、第二馈电点B以外的馈电点)和辐射体(除第一辐射体111、第二辐射体121以外的辐射体)来支持对第一频段的射频信号的收发，可以采用共用馈电点，共用辐射体的方式来实现对第一频段和第三频段的射频信号的收发，可以降低成本，减少天线装置的占用空间(例如，可以节约弹片组件等)，有利于天线装置的小型化设置。
如图4所示，在其中一个实施例中，第一天线组件110还包括第一滤波电路112和第二滤波电路113，其中，第一滤波电路112的输入端与第一馈源S1连接，第二滤波电路 113的输入端与第三馈源S3连接，第一滤波电路112和第二滤波电路113的第二端分别与第一馈电点A连接，第一滤波电路112和第二滤波电路113输出的馈电信号的频段不同。其中，第一滤波电路112为高通滤波电路，可以滤掉第三频段(例如，低频段)的射频信号，仅允许第一频段的射频信号通过。第二滤波电路113为低通滤波电路，可以滤掉第一频段(例如，超高频段)的射频信号，仅允许第三频段的射频信号通过。
在本申请中，第一馈电点A与第三馈电点C为同一馈电点，也即第一馈源S1和第三馈源S3共用同一馈电点，通过在馈源与馈电点之间设置第一滤波电路112和第二滤波电路113，可以保证第一馈电信号和第三馈电信号的馈电隔离度，以进一步提高对第一频段和第三频段的射频信号的收发性能。
如图5所示，在其中一个实施例中，第一天线组件110还包括：分别与第一馈源S1、第一滤波电路112的输入端连接的第一匹配电路114，用于调谐第一频段的射频信号的谐振频率。其中，第一匹配电路114可以包括电容、电阻和电感中的至少一种，或者多个的组合。在本申请实施例中，对第一匹配电路114所包括的调频器件的器件类型以及器件与器件之间的连接关系不做进一步的限定。
其中，第一馈源S1提供的第一馈电信号经第一匹配电路114、第一滤波电路112、第一馈电点A可馈入至第一辐射体111。在本实施例中，通过调节第一匹配电路114的选频参数(例如，可包括电阻值、电感值及电容值)可以调节第一频段的谐振频率，以使第一天线组件110可以实现对超高频的射频信号，例如，NR-77、78、79等频段的覆盖，也可以实现超宽带的载波聚合功能。
如图6-图8所示，在其中一个实施例中，第一天线组件110还包括：第二匹配电路115、第一可变调频电路116和第二可变调频电路117中的至少一个。其中，第二匹配电路115、第一可变调频电路116和第二可变调频电路117可用于调谐第三频段的射频信号的谐振频率。示例性的，第二匹配电路115、第一可变调频电路116和第二可变调频电路117可独立或共同对第三频段的射频信号的谐振频率进行调节。
第二匹配电路115分别与第一馈源S1、第二滤波电路113输入端连接。其中，第二匹配电路115可包括电容、电阻和电感中的至少一种，或者多个的组合。在本申请实施例中，对第二匹配电路115所包括的调频器件的器件类型以及器件与器件之间的连接关系不做进一步的限定。其中，第三馈源S3提供的第三馈电信号经第二匹配电路115、第二滤波电路113、第一馈电点A可馈入至第一辐射体111。在本实施例中，通过调节第二匹配电路115的选频参数(例如，可包括电阻值、电感值及电容值)可以调节第三频段的谐振频率，以使第一天线组件110可以实现对低频段的射频信号的覆盖，也可以实现超宽带的载波聚合功能。
请继续参考图7，第一可变调频电路116的第一端与第二滤波电路113连接，第一可变调频电路116的第二端接地。可选的，请继续参考图8，第二可变调频电路117的第一端还可以与第一辐射体111上连接，第一可变调频电路116的第二端接地。第二可变调频电路117的第一端与第一辐射体111上的第一调频点D连接，第二可变调频电路117的第二端接地。在其中一个实施例中，第一辐射体111包括相对设置的第一接地端GND1和第一自由端F1，其中，第一调频点D设置在第一馈电点A与第一接地端GND1之间。在本申请实施例中，第一自由端F1可以理解为第一辐射体111中临近缝隙101设置的端部。
第一可变调频电路116和第二可变调频电路117可分别设置多个调频通路，其中，同一调频电路中的各调频通路的调频参数不完全相同。示例性的，如图9所示，第一可变调频电路116可包括第一开关单元1161和多个第一可变调频单元1162，各第一可变调频单元1162的调频参数不同。天线装置或电子设备可以根据实际通信需求或电子设备的握持状态来控制第一开关单元1161来导通目标第一可变调频单元1162与第一辐射体111之间的通路。各调频通路上分别设置有一可变调谐单元。如图10所示，第二可变调频电路117 可包括第二开关单元1171和多个第二可变调频单元1172，各第二可变调频单元1172的调频参数不同。天线装置或电子设备可以根据实际通信需求或电子设备的握持状态来控制第二开关单元1171来导通目标第二可变调频单元1172与第一辐射体111之间的通路。其中，目标第一可变调频单元1162为多个第一可变调频单元1162中的至少一个，目标第二可变调频单元1172为多个第二可变调频单元1172中的至少一个。
基于第一天线组件110中设置的第二匹配电路115、第一可变调频电路116和第二可变调谐电路117，天线装置支持第一谐振模式、第二谐振模式、第三谐振模式及第四谐振模式，以支持第三频段的射频信号的收发。可以理解的是，第一谐振模式、第二谐振模式、第三谐振模式及第四谐振模式为第一天线组件110的四种谐振模式，且由第一辐射体111产生。
第一谐振模式、第二谐振模式、第三谐振模式及第四谐振模式分别为从第一接地端GND1至缝隙101对应的第一辐射体111对应的基模，如图11所示。其中，图11为图7所示的天线装置收发第三频段的射频信号的回波损耗曲线示意图。需要说明的是，在图11中的第一谐振模式(模式1)、第二谐振模式(模式2)、第三谐振模(模式3)式及第四谐振模式(模式4)在同一时刻只存在一个谐振模式。第一可变调频电路116和第二可变调频电路117中的至少一个可以用于调节第三频段的谐振频率的偏移，例如，通过第一可变调频电路116和第二可变调频电路117中的至少一个来增高或降低谐振频率，从而使得第一天线组件110可以收发第三频段的射频信号时的谐振频率不同。具体请参见图11，模式1、模式2、模式3、模式4对应的第三频段的谐振频率依次增大。
需要说明的是，在本申请实施例中，第一天线组件110包括但不限于上述四种谐振模式，通过设置第一可变调频电路116和第二可变调谐电路117中配置的调谐通路的数量，可以使得第一天线组件110能够支持对低频600-1000M带宽内的频段的射频信号的收发。
在本实施例中，通过设置第二匹配电路115、第一可变调频电路116和第二可变调频电路117，可以调节第三频段的射频信号的谐振频率，也可以调节上述谐振模式的谐振频率，进而可以使得第一天线组件110对低频段的部分频段或全部频段的覆盖，及在所需频段得到较高的效率，可以进一步提高对低频信号的收发性能。
在其中一个实施例中，天线装置还支持第五谐振模式，以支持第二频段的第一子频段的射频信号的收发。第二频段的第一子频段可以为中高频信号中的中频信号。其中，第五谐振模式可以理解为环形(LOOP)模式。
在其中一个实施例中，第五谐振模式为从第一馈电点A至第一接地端GND1对应的第一辐射体111的二分之一波长模式。在LOOP模式下，通过调节第一可变调频电路116和第二可变调谐电路117中配置的调谐通路的谐振参数，可以调节第五谐振模式的谐振频率。例如，若选择谐振参数(例如，电感)较低的可变调谐单元作为目标可变调谐单元时，其第五谐振模式的谐振频率将往高频点偏移。
在本实施例中，天线装置可以选择支持对第一至第四谐振模式中的任一模式，也可以支持第五谐振模式。这样，天线装置可以根据实际通信需求，来调节第一可变调频电路116和第二可变调谐电路117中配置的调谐通路的谐振参数，进而使第一天线组件110可工作在目标谐振模式下，可以根据通信需求来动态调整谐振模式，以提高天线装置的通信性能。
如图12所示，在其中一个实施例中，第二辐射体121包括相对设置的第二接地端GND2和第二自由端F2。其中，第二自由端F2为第二辐射体121靠近缝隙101的端部。第二辐射体121还设有第一连接点G，第一连接点G靠近第二自由端F2设置，第二天线组件120还包括：第三匹配电路122。第三匹配电路122的第一端与第一连接点G连接，第三匹配电路122的第二端接地设置，用于调谐第一频段的射频信号的谐振频率。其中，第三匹配电路122可包括电容、电阻和电感中的至少一种，或者多个的组合。可选的，第 三匹配电路122还可包括开关等，通过对开关的控制，可以改变该匹配电路的调频参数。在本申请实施例中，对第三匹配电路122所包括的调频器件的器件类型以及器件与器件之间的连接关系不做进一步的限定。其中，第一馈源S1提供的第一馈电信号经第一匹配电路114、第一滤波电路112、第一馈电点A可馈入至第一辐射体111，再经缝隙101与第二辐射体121容性耦合。其中，第三匹配电路122对中高频的射频信号的表现为容性较小，类似开路，对超高频的射频信号表现为低阻抗短路效果。换而言之，第一馈源S1提供的第一馈电信号，在第三匹配电路122处低阻抗下地。
在本实施例中，通过调节第三匹配电路122的选频参数(例如，可包括电阻值、电感值及电容值)可以调节第一频段的谐振频率，以使第二天线组件120可以实现对第一频段的射频信号的覆盖。在本实施例中，第二天线组件120可协同第一天线组件110来支持对第一频段的射频信号的收发，可以提高对超高频信号的收发性能。
在其中一个实施例中，天线装置还支持第六谐振模式和第七谐振模式，以支持第一频段的射频信号的收发。可以理解的是，第六谐振模式和第七谐振模式为第二天线组件120的其中两种谐振模式，且由第二辐射体121产生。
第六谐振模式为从第一连接端至缝隙101对应的第二辐射体121的基模，以辅助支持对第一频段的第一子频段的射频信号的收发。第七谐振模式为第二天线组件120工作在第二辐射体121的第二接地端GND2至缝隙101的三次模，以支持对第一频段的第二子频段的射频信号的收发。
图13为图12所示的天线装置收发第三频段的射频信号的回波损耗曲线示意图。在其中一个实施例中，第六谐振模式(模式6)、第七谐振模式(模式7)分别对应于第一频段的第一子频段、第二子频段。第一频段的第一子频段的频率范围为3800～3900MHz之间；第一频段的第二子频段的频率范围为4700～4800MHz之间。
在本申请实施例中，在不设置合路器的情况下，第二辐射体121除了可以实现对第一频段的收发处理，还可以支持对第二频段的射频信号的收发处理。第二天天线组件可以支持对4G-LTE信号和5G-NR信号的收发处理，例如，包括LTE-1/2/3/4/7/32/34/38/39/40/41频段信号，以及NR-1/3/7/40/41/77/78/79频段信号等，可以实现中高频和超高频的载波聚合，同时，还可以支持低频和中高频，以及低频与超高频的双连接(LTE NR Double Connect，ENDC)组合，其可以降低收发链路上的插损，提高通信性能，还可以节约成本，减小天线装置的占用空间。
如图14所示，在其中一个实施例中，第二馈电点B设置在第一连接点G与第二接地端GND2之间。第二天线组件120还包括：第四匹配电路123和第三可变调频电路124，其中，第四匹配电路123和第三可变调频电路124可用于调节第二频段的射频信号的谐振频率。

本申请实施例提供电子设备，包括前述的天线装置，相比于相关技术中，需要在第一馈源和第二馈源与馈电点之间增加合路器，以将不同的馈电信号经过合理处理后加载在同一馈电点的方式，可以避免使用合路器，进而可以降低第一频段和第二频段的射频信号的收发链路上合路器带来的链路插损，以提高对第一频段和第二频段的射频信号的收发性能，同时，还可以避免使用合路器，以降低成本。进一步的，第一天线组件可以支持对超高频的射频信号的收发，第二天线组件可以支持对超高频和/或中高频的射频信号的收发处理，可以利用较少的天线辐射体实现较宽频段的覆盖，同时也可以实现中高频以及超高频的载波聚合(Carrier Aggregation，CA)及4G-LTE信号与5G-NR的双连接(LTE NR Double Connect，ENDC)组合，可以进一步提高天线装置的通信性能。
如图16所示，在一实施例中，以电子设备为手机为例进行说明。在其中一个实施例中，电子设备10还包括：边框11、显示屏组件12和控制模块13。其中，显示屏组件12，设置在边框11上，显示屏组件12包括显示屏，显示屏可以采用OLED(Organic Light-Emitting Diode，有机发光二极管)屏幕，也可以采用LCD(Liquid Crystal Display，液晶显示)屏幕，显示屏可用于显示信息并为用户提供交互界面。显示屏的形状可以为矩形或弧角矩形，弧角矩形有时也可以称为圆角矩形，即矩形的四个角采用了圆弧过渡，矩 形的四条边大致呈直线段。
边框11可以采用金属材料例如铝合金或者镁合金或者不锈钢制成，边框11设于显示屏组件12外周以用于支撑和保护显示屏组件12。边框11可以进一步向电子设备内部延伸形成中板，一体成型的中板和边框11有时也被称为中框。显示屏组件12可以采用点胶等工艺固定连接于边框11或者中板。
在其中一个实施例中，参考图16，边框11大致呈矩形框状，中框为金属导电中框，其包括相对设置的第一导电边框1101和第三导电边框1103，以及相对设置的第二导电边框1102和第四导电边框1104，其中，第一导电边框1101、第二导电边框1102、第三导电边框1103和第四导电边框1104依次首尾连接。其中，第一导电边框1101、第三导电边框1103可以对应理解为电子设备的顶边框、底边框，第二导电边框1102和第四导电边框1104可以对应理解为电子设备的第一侧边框和第二侧边框。具体的各边框11间的连接可以为直角连接或者圆弧过渡连接。进一步的，天线装置中的第一辐射体和第二辐射体形成在任一导电边框上。示例性的，如图17所示，天线装置的第一辐射体111和第二辐射体121都可以形成在第二导电边框1102上，其中，第二辐射体121靠近第一导电边框1101设置。
电子设备还可包括主板14，其中，天线装置中的第一馈源S1、第二馈源S2、各匹配电路、各可变调谐电路均设置在主板14上，第一辐射体111的第一接地端GND1、第二辐射体121的第二接地端GND2可与主板14的接地层连接。

如图19所示，可选地，天线装置中的第一辐射体111和第二辐射体121分别形成在相邻设置的两个导电边框11上。示例性的，第一辐射体111和第二辐射体121分别形成在相邻设置的第一导电边框1101、第二导电边框1102上。可以理解的是，靠近相邻设置的两个导电边框11的连接区域的边框11可以理解为拐角边框11。天线装置的第一辐射体111和第二辐射体121可设置在电子设备的任一拐角边框11。其中，电子设备可包括第一拐角边框11、第二拐角边框11、第三拐角边框11和第四拐角边框11。其中，天线装置的第一辐射体111和第二辐射体121可设置在电子设备的第一至第四拐角边框11中的任一拐角边框11。
需要说明的是，在本申请实施例中，天线装置中第一辐射体111、第二辐射体121的形成在导电边框11的区域不限于上述举例说明。
在其中一个实施例中，电子设备还包括控制模块13，用于获取电子设备的握持状态，并根据握持状态控制天线装置的谐振模式，其中，电子设备处于不同握持状态时，第一天线组件110工作在第一辐射体111的谐振模式不同，握持状态包括竖屏握持状态和横屏握持状态。
其中，电子设备的握持状态可以基于电子设备中传感器模组的运动数据获取，具体的，传感器数据可包括重力数据、陀螺仪数据、加速度数据等。可选地，电子设备的握持状态可以基于电子设备中显示屏的显示模式来确定。示例性的，若当前显示屏为横屏显示，其对应的握持状态为横屏握持状态；若当前显示屏为竖屏显示，其对应的握持状态为竖屏握持状态。需要说明的是，在本申请实施例中，电子设备握持状态的获取方式不限于上述举例说明。
在本实施例中，电子设备可以基于电子设备当前的握持状态，来控制天线装置中第一天线组件110工作在第一辐射体111的谐振模式，以使第一辐射体111可以支持对不同频段射频信号的收发处理，这样就可以基于电子设备的当前握持状态来调整第一天线组件110的谐振模式，以使电子设备在不同的握持状态下，都可以实现高性能的通信。
为了便于说明，图17-19所示的电子设备为例进行说明。
在其中一个实施例中，当电子设备工作在竖屏握持状态时，控制模块用于控制天线装置中的第一可变调频电路和第二可变调频电路的调频参数，以使第一天线组件工作在第一谐振模式、第二谐振模式、第三谐振模式及第四谐振模式中的至少一种，以支持对第三频段的射频信号的收发。
进一步的，控制模块用于控制天线装置中的第一可变调频电路的调频参数，以使第一天线组件工作在第六谐振模式，以支持对第一频段的射频信号的收发。
当电子设备处于横屏握持状态时，天线装置的缝隙可能会被遮挡，若缝隙被遮挡，其天线装置基于缝隙的多种谐振模式将被破坏。基于此，当电子设备处于横屏握持状态时，控制模块用于控制天线装置中的第一可变调频电路和第二可变调频电路的调频参数，以使第一天线组件工作在第五谐振模式，以支持第二频段的第一子频段的射频信号的收发。其中，第五谐振模式为环形(LOOP)模式。在其中一个实施例中，第五谐振模式为第一天线组件作在第一辐射体111的第一馈电点至第一接地端的二分之一波长模式。在LOOP模式下，通过调节第一可变调频电路和第二可变调频电路中配置的调谐通路的谐振参数，可以调节第五谐振模式的谐振频率。例如，若选择谐振参数(例如，电感)较低的可变调谐单元作为目标可变调谐单元时，其第五谐振模式的谐振频率将往高频点偏移。
如图20所示，以中频段的射频信号为例，电子设备处于横屏握持状态(或缝隙被部分或全部遮挡)，且第一天线组件未工作在第五谐振模式，中频段的射频信号的谐振(参考曲线1)偏到1.55G，此时中频段的射频信号的总效率(参考曲线3)急剧下降到-13～-15dB。本申请实施例中，若电子设备处于横屏握持状态，可控制第一天线组件工作在第五谐振模式(参考曲线2)，总效率(参考曲线4)峰值能接近-10dB，性能提升非常大，保证横屏握持状态(或天线装置的缝隙被遮挡)下天线装置的通信性能。
在其中一个实施例中，电子设备包括至少两个天线装置，其中，各天线装置对应形成于不同的导电边框。每一天线装置中的辐射体可形成在任一导电边框或任一拐角边框。示例性的，电子设备可包括第一天线装置和第二天线装置，第一天线装置中的辐射体可形成于第二导电边框，第二天线装置中辐射体可形成于第三导电边框。

可选的，第一天线装置中的辐射体可形成于第一导电边框，第二天线装置中辐射体可形成于第二拐角边框。
需要说明的是，电子设备中第一天线组价、第二天线装置的形成于导电边框11的区域不限于上述举例说明。
进一步的，控制模块13可控制一个天线装置的收发4G LTE信号，可控制另一个天线装置的收发5G NR信号，以实现4G LTE信号与5G NR信号的双连接。
在其中一个实施例中，电子设备包括第一天线装置、第二天线装置、第三天线装置和第四天线装置。其中，每一天线装置中的辐射体可形成在任一导电边框或任一拐角边框。
进一步的，控制模块可控制四个天线装置分别支持对低频段、中高频段以及超高频段的射频信号的收发，以实现全频段的载波聚合功能，还可以分别控制四个天线装置分别支持对5G NR信号的收发，以实现4*4多输入多输出(Multiple Input Multiple Output，MIMO)功能，还可以支持对不同ENDC组合的4G LTE信号与5G NR信号双连接等，进而可提升电子设备的通信性能。
如图21所示，进一步的，以电子设备为手机10为例进行说明，具体的，如图21所示，该手机10可包括存储器21(其任选地包括一个或多个计算机可读存储介质)、处理电路22、控制模块23、输入/输出(I/O)子系统24和至少一如前述任一实施例中的天线装置25。这些部件任选地通过一个或多个通信总线或信号线29进行通信。本领域技术人员可以理解，图21所示的手机10并不构成对手机的限定，可以包括比图示更多或更少的部件， 或者组合某些部件，或者不同的部件布置。图21中所示的各种部件以硬件、软件、或硬件与软件两者的组合来实现，包括一个或多个信号处理和/或专用集成电路。
存储器21任选地包括高速随机存取存储器，并且还任选地包括非易失性存储器，诸如一个或多个磁盘存储设备、闪存存储器设备、或其他非易失性固态存储器设备。示例性的，存储于存储器21中的软件部件包括操作系统211、通信模块(或指令集)212、全球定位系统(GPS)模块(或指令集)213等。
处理电路22和其他控制电路23可以用于控制手机10的操作。该处理电路22可以基于一个或多个微处理器、微控制器、数字信号处理器、基带处理器、功率管理单元、音频编解码器芯片、专用集成电路等。
当电子设备工作在竖屏握持状态时，控制模块23用于控制天线装置25中的第一可变调频电路和第二可变调频电路的调频参数，以使第一天线组件工作在第一谐振模式、第二谐振模式、第三谐振模式及第四谐振模式中的至少一种，以支持对第三频段的射频信号的收发。
进一步的，控制模块23用于控制天线装置25中的第一可变调频电路的调频参数，以使第一天线组件工作在第六谐振模式，以支持对第一频段的射频信号的收发。
其中，I/O子系统24将手机10上的输入/输出外围设备诸如键区和其他输入控制设备耦接到外围设备接口23。I/O子系统24任选地包括触摸屏、按键、音调发生器、加速度计(运动传感器)、周围光传感器和其他传感器、发光二极管以及其他状态指示器、数据端口等。示例性的，用户可以通过经由I/O子系统24供给命令来控制手机10的操作，并且可以使用I/O子系统24的输出资源来从手机10接收状态信息和其他输出。例如，用户按压按钮241即可启动手机或者关闭手机。
以上实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
