具体实施例
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。

在本申请实施例中，电子设备100包括第一壳体10、第二壳体20以及转动组件30，第一壳体10以及第二壳体20相对转动组件30可以旋转，从而可以使得电子设备100在折叠状态以及展开状态中进行切换。由于第一壳体10上设置有第一天线12，第二壳体20上设置有第二天线22，且第二天线22与第一天线12在第二壳体20上的至少部分投影区域重合，因此，在电子设备100处于折叠状态，且第一天线12的工作频段与第二天线22的工作频段相同的情况下，可以控制第一天线12处于第一工作状态，第二天线22处于第二工作状态，第一工作状态下的第一天线12与第二工作状态下的的人天线中的电流流向相反，从而可以避免第一天线12以及第二天线22之间相互影响，保证第一天线12以及第二天线22之间的同频高隔离度性能。
需要说明的是，第一外壳以及第二外壳可以相对转动组件30进行旋转，使得电子设备100处于折叠状态或展开状态，如图2所示，图2中角α即为第一外壳与第二外壳之间的夹角。其中，电子设备100的折叠状态可以为内折或外折，当电子设备100折叠后显示屏幕位于内侧时，即外壳处于可观察到的状态时，这种折叠方式为内折，如图3所示，此时；当叠合后显示屏幕位于外侧时，即屏幕处于可观察到的状态时，这种折叠方式为外折，如图4所示。本申请实施例对于电子设备100的折叠状态不作具体限定。
还需要说明的是，第一屏幕11设置在第一外壳上，第二屏幕21设置在第二外壳上，第一天线12可以处于第一外壳与第一屏幕11之间的非屏幕区域中的任意区域，相应的第二天线22则可以处于第二外壳以及第二屏幕21之间的非屏幕区域中的任意区域，且第二天线22与第一天线12存在重叠区域。如图1所示，即为第一天线12以及第二天线22的示意位置。

第一天线12包括第一辐射结构121以及第一馈电模块122，第一辐射结构121与第一馈电模块122连接，第二天线22包括第二辐射结构221以及第二馈电模块222，第二辐射结构221以及第二馈电模块222连接，从而可以通过第一馈电模块122向第一天线12馈入馈电信号，通过第二馈电模块222向第二天线22馈入馈电信号，使得第一天线12以及第二天线22可以正常工作。
第二馈电模块222包括相位控制模块229，相位控制模块229可以控制第二馈电模块222中馈电信号的相位，使得第二馈电模块222馈入第二辐射结构221的两路馈电信号的相位差为180°，使得第二天线22中的电流与第一天线12中的电流的流向相反。由于第二天线22中的电流与第一天线12中的电流的流向相反，因此，在第一天线12以及第二天线22的工作频段相同的情况下，可以避免第一天线12以及第二天线22互相影响，改善电子设备100在折叠状态下两天线间的同频带间隔离度。
另外，在一些实施例，如图5所示，第一馈电模块122包括第一激励源126、第一开关以及第一匹配电路127，第一开关包括第一子开关1281、第二子开关1282以及第三子开关1283，第一子开关1281与第一辐射结构121的第一接触点连接，第二子开关1282的一端分别与第一辐射结构121的第二接触点以及第三接触点连接，第二子开关1282的另一端接地，第三子开关1283与第一辐射结构121的第四接触点连接；第一匹配电路127的一端与第一激励源126连接，第一匹配电路127的另一端与第一子开关1281以及第三子开关1283连接。

需要说明的是，第一相位控制模块2291以及第二相位控制模块2292连接，从而第一相位控制模块2291与第二相位控制模块2292可以作为一个整体对两路馈电信号的相位差进行控制。当然，第一相位控制模块2291与第二相位控制模块2292之间还可以不连接，也即是，第一相位控制模块2291以及第二相位控制模块2292相互独立，第一相位控制模块2291控制一路馈电信号的相位，第二相位控制模块2292控制另一路馈电信 号的相位，使得两路馈电信号的相位差满足条件。

在第一壳体10以及第二壳体20为非金属壳体的情况下，第一辐射结构121可以由设置在第一壳体10内的某区域的具有辐射功能的金属形成，第二辐射结构221则可以由设置在第二壳体20内相应区域的具有辐射功能的金属形成，其中，第一壳体10内的某区域与第二壳体20内相应区域具有重叠部分。当然，在第一壳体10以及第二壳体20为金属壳体的情况下，第一辐射结构121也可以由设置在第一壳体10内的某区域的具有辐射功能的金属形成，第二辐射结构221也可以由设置在第二壳体20内相应区域的具有辐射功能的金属形成。对于第一辐射结构121以及第二辐射结构221的具体形式，本申请实施例不作具体限定。
另外，在一些实施例，在电子设备100处于折叠状态的情况下，第一子开关1281、第三子开关1283均可以闭合，第二子开关1282可以断开，以使第一天线12处于第一工作状态；且第二开关228可以闭合，第一相位控制模块2291与第二相位控制模块2292处于工作状态，第一相位控制模块2291以及第二相位控制模块2292控制进入第三枝节224的馈电信号以及进入第四枝节225的馈电信号的相位差为180°，以使第二天线22处于第二工作状态。
在第一子开关1281、第三子开关1283闭合，第二子开关1282断开的情况下，第一 匹配电路127与第一枝节124以及第二枝节125均处于连通状态，第二子开关1282与第二接触点之间断开，第一天线12构成缝隙天线，且第一天线12处于半波模式，此时，第一天线12处于第一工作状态，第一枝节124以及第二枝节125中的电流流向相反，参照图8，图8中箭头方向即为电流方向，第一枝节124中电流相对第一断缝123向左流动，第二枝节125中电流相对第一断缝123向右流动。即，第一天线12处于第一工作状态时，第一天线12构成缝隙天线，且处于半波模式，第一枝节124以及第二枝节125中的电流反向。
在第二开关228闭合的情况下，第二匹配电路227与第三枝节224以及第四枝节225均导通，第二激励源226的馈电信号分两路分别馈入第三枝节224以及第四枝节225，第一相位控制模块2291以及第二相位控制模块2292则可以控制两路馈电信号的相位差满足180°，此时，第二天线22处于第二工作状态，第二天线22构成缝隙天线，且第二天线22处于半波模式，第三枝节224以第四枝节225中的电流流向相同，参照图10，图10中箭头方向即为电流方向，第三枝节224中的电流相位相对第二断缝223向右流动，第四枝节225中的电流相对第二断缝223也向右流动。即第二天线22处于第二工作状态时，第二天线22构成缝隙天线，且处于半波模式，第三枝节224以及第四枝节225中的电流通向。
在电子设备100处于折叠状态的情况下，第一子开关1281、第三子开关1283闭合，第二子开关1282断开，第二开关228闭合，使得第一天线12处于第一工作状态，第二天线22处于第二工作状态。第一天线12的第一工作状态以及第二天线22的第二工作状态之间的电流反向，模式天然正交，可以避免第一天线12与第二天线22之间影响。
另外，在一些实施例，在电子设备100处于展开状态下，第二子开关1282可以断开，第一子开关1281或第三子开关1283可以闭合，第一天线12为IFA天线，且第一天线12处于半波模式；或，第一子开关1281、第三子开关1283均可以闭合，第二子开关1282可以断开，第一天线12为缝隙天线，且第一天线12的天线模式为半波模式；或，第一子开关1281、第二子开关1282以及第三子开关1283均可以闭合，第一天线12为全波模式。

在第一子开关1281、第三子开关1283均闭合，第二子开关1282断开的情况下，第一天线12处于状态二，即第一天线12的第一工作状态，此时第一天线12构成缝隙天线，且处于半波模式，第一枝节124以及第二枝节125中的电流反向。参照图8，示出了第一天线12处于状态二时的天线模式简图。
在第一子开关1281、第二子开关1282以及第三子开关1283均闭合的情况下，第一天线12处于状态三，此时第一天线12为Loop天线，且第一天线12处于全波模式。参照图9，示出了第一天线12处于状态三时的天线模式简图。
另外，在一些实施例，在电子设备100处于展开状态下，第二开关228可以闭合，第一相位控制模块2291以及第二相位控制模块2292控制进入第三枝节224的馈电信号以及进入第四枝节225的馈电信号的相位差为180°，第二天线22为缝隙天线，且第二天线22处于半波模式；或，第二开关228可以断开，第二天线22为IFA天线，且第二天线22处于半波模式。
在电子设备100处于展开状态的情况下，第二天线22具有两种工作状态，分别为状态四以及状态五，第二天线22可以在两种状态中的任意一种状态下工作。
在第二开关228闭合的情况下，第二天线22处于状态四，即第二天线22的第二工作状态，此时，第二天线22构成缝隙天线，且处于半波模式，第二枝节125以及第四枝节225中的电流同向。参照图10，示出了第二天线22处于状态四时的天线模式简图。
在第二开关228断开的情况下，第二天线22处于状态五，此时第二天线22构成IFA天线，参照图11，示出了第二天线22处于状态五时的天线模式简图，此时第一天线12处于半波模式。
需要说明的是，在本申请实施例中，可以在不同的情况下在折叠电子设备100时，避免处于折叠状态的电子设备100中的第一天线12与第二天线22相互影响，例如，在第一天线12与第二天线22均不工作的情况下，折叠电子设备100，可以控制第一天线12处于第一工作状态，第二天线22处于第二工作状态，此时相位控制模块229则可以控制进入第二辐射结构221的两路馈电信号的相位差为180°，此时第二天线22中流通有电流，且第二天线22中的电流流向与第一天线12中的电流流向相反；或者，还可以在第一天线12与第二天线22工作的情况下折叠电子设备100，具体的，第一天线12可以处于状态一、状态二以及状态三中的任一种状态，第二天线22可以处于状态五，此时折叠电子设备100，可以控制第一天线12处于第一工作状态，而相位控制模块229则可以控制进入第二辐射结构221的两路馈电信号的相位差为180°，使得在第二天线22中的电流方向改变，从而第二天线22处于第二工作状态，即状态四，以使第二天线22中的电流流向与第一天线12中的电流流向相反。
其中，第一开关与第二开关228可以与电子设备100的控制模块电连接，例如电子设备100中的CPU，用户可以向电子设备100发出模式切换指令，电子设备100的控制模块根据模式切换指令控制第一开关以及第二开关228所处的状态，进而控制第一天线12与第二天线22的工作状态。为了便于用户使用电子设备100，电子设备100还可以检测电子设备100是否处于折叠状态，在电子设备100处于折叠状态的情况下，控制模块自动控制第一天线12处于第一工作状态，控制第二天线22处于第二工作状态。
另外，在一些实施例，如图5、图6所示，第一开关可以靠近第一激励源126设置， 第二开关228可以靠近第二激励源226设置。
第一开关靠近第一激励源126设置，第二开关228靠近第二激励源226设置，从而可以降低枝节加载对阻抗的影响。
需要说明的是，第一开关以及第二开关228的位置可以根据电子设备100的性能进行匹配设置，以降低枝节加载对阻抗的影响。例如，第一开关与第一激励源126之间的距离可以为4mm、5mm、6mm等等，第二开关228与与第二激励源226之间的距离也可以为4mm、5mm、6mm等等。对于第一开关以及第二开关228的具体设置位置，本申请实施例不作具体限定。
还需要说明的是，在本申请实施例中，电子设备100包括但不限于手机、平板电脑、笔记本电脑、掌上电脑、车载终端、可穿戴设备、以及计步器等。
另外，本申请实施例中第一天线12以及第二天线22不局限于在同频状态下使用，即当电子设备100处于折叠状态时，第一天线12与第二天线22可以在工作频段相同的情况下工作，第一天线12以及第二天线22还可以在不同工作频段下工作。在第一天线12以及第二天线22在相同工作频段下工作时，第一天线12处于第一工作状态，第二天线22处于第二工作状态，则可以避免第一天线12与第二天线22之间相互影响。在第一天线12以及第二天线22在不同工作频段下工作时，第一天线12可以处于第一工作状态，第二天线22可以处于第二工作状态；另外，第一天线12与第二天线22还可以处于其它状态。
