下面结合图1-图9描述根据本申请实施例的天线模组。
如图1所示，根据本申请一些实施例的天线模组，包括：主天线单元和寄生天线单元。
在该实施例中，主天线单元设置于电子设备的第一主体130；寄生天线单元设置于电子设备的第二主体140。
第一主体130和第二主体140通过连接组件150连接，且第一主体130与第二主体140在展开状态和折叠状态之间可切换。
连接组件150可以为铰链结构或者其他可实现翻折功能的结构。
具体地，第一主体130与第二主体140可以通过折叠的方式在展开状态和折叠状态之间切换，其中，折叠可以为内翻折。
寄生天线单元与主天线单元设置于同一端。
其中，主天线单元的至少部分区域和寄生天线单元的至少部分区域均为金属导电材质。
在电子设备正常工作的情况下，在展开状态下，第二主体140中的寄生天线单元主要受到地电流的激励，即第一主体130中的主天线单元通过 地电流经由连接组件150激励起寄生天线单元上的电流。
在折叠状态下，第二主体140中的寄生天线单元则同时受到空间耦合激励和地电流的激励。
示例性地，主天线单元的形式可以表现为常见的双频倒F天线(Inverted F Antenna，IFA)。
当然，在其他实施例中，主天线单元的形式也可以为单极子、平面倒F天线(Planar Inverted F-shaped Antenna，PIFA)或环天线(LOOP Antenna)等形式，本申请不作限定。
寄生天线单元与主天线单元的形式保持一致。
在第一主体130与第二主体140为展开状态的情况下，主天线单元靠近连接组件150的一端与寄生天线单元靠近连接组件150的一端之间的最短距离为(nλ)/2；其中，λ为主天线单元的目标工作波长，n＞0且n可以为奇数或偶数。
其中，在n为偶数时，n可以取值2、4、6或其他任意正偶数值；在n为奇数时，n可以取值1、3或其他任意正奇数值，本申请不作限定。
在本申请中，不对主天线单元的工作频率范围或工作频段数量进行限定，可以应用于4G、5G或其他任何网络。
需要说明的是，在主天线单元正常工作的情况下，当n为偶数时，在展开状态下，主天线单元与寄生天线单元中的电流同向；在折叠状态下，主天线单元与寄生天线单元中的电流反向。
图1示例了一种在n为偶数时，展开状态下主天线单元与寄生天线单元中的电流方向，如箭头方向所示，均为逆时针方向。
当n为奇数时，在展开状态下，主天线单元与寄生天线单元中的电流反向；在折叠状态下，主天线单元与寄生天线单元中的电流同向。
图4示例了一种在n为奇数时，展开状态下主天线单元与寄生天线单元中的电流方向，如箭头方向所示，其中，主天线单元中的电流方向为逆时针方向，寄生天线单元中的电流方向为顺时针方向。
图5示例了一种在n为奇数时，折叠状态下主天线单元与寄生天线单元中的电流方向，其中，虚线箭头表示空间耦合激励的方向，实线箭头表示地电流的激励方向，可见空间耦合激励的方向与地电流的激励方向相反。
需要说明的是，在主天线单元与寄生天线单元中的电流同向的情况下其对应的主天线单元的天线辐射效率，要高于在主天线单元与寄生天线单元中的电流反向的情况下其对应的主天线单元的天线辐射效率。
例如，在一些实施例中，可以将展开状态下的第一回地端112与第二回地端122之间的最短距离设置为偶数倍的λ/2，使得在展开状态下，主天线单元与寄生天线单元中的电流同向，以提高展开状态下主天线单元的天线辐射效率。
又如，在又一些实施例中，可以将展开状态下的第一回地端112与第二回地端122之间的距离设置为奇数倍的λ/2，使得在展开状态下，主天线单元与寄生天线单元中的电流反向，而在折叠状态下，主天线单元与寄生天线单元中的电流同向，以提高折叠状态下主天线单元的天线辐射效率。
根据本申请实施例的天线模组，通过将主天线单元与寄生天线单元之间的距离设置为(nλ)/2，并基于实际需求选择n的奇偶性，以基于实际需求调节展开状态下的主天线单元与寄生天线单元中的电流的方向，从而选择性地提升电子设备在展开状态下的主天线单元的天线辐射效率或者在折叠状态下的主天线单元的天线辐射效率，具有较高的灵活性和可用性，且硬件结构简单，无需增加额外的元器件，具有较低的设计成本。
继续参考图1，根据本申请的一些实施例，主天线单元包括馈电端114和主天线臂111，馈电端114连接于主天线臂111与第一主体130之间，且所述馈电端114的一端与主天线臂111连接，另一端通过第一主体130接地，寄生天线单元包括寄生天线臂121，且主天线臂111与寄生天线臂121的长度相等。
在该实施例中，主天线臂111与第一主体130处于同一平面，且主天线臂111垂直于连接组件150；寄生天线臂121与第二主体140处于同一 平面，且寄生天线臂121垂直于连接组件150。
主天线单元和寄生天线单元内部均设有净空区。
在一些实施例中，主天线单元内部的第一净空区171和寄生天线单元内部的第二净空区172大小相同且对称。
净空区用于降低在折叠状态下，第二主体140的金属边框(相当于金属地)对于主天线单元的天线性能的影响。
主天线臂111设置于第一主体130，且主天线臂111与第一主体130之间形成第一净空区171；寄生天线臂121设置于第二主体140，且寄生天线臂121与第二主体140之间形成第二净空区172。
馈电端114用于供电。
馈电端114设置于第一主体130内部的净空区且分别与主天线臂111与第一主体130电连接。
在一些实施例中，主天线臂111与寄生天线臂121的长度均为λ/4；其中，λ为主天线单元的目标工作波长，n＞0且n为奇数或偶数。
在另一些实施例中，主天线臂111与寄生天线臂121的长度可以为其他值，将在下文中进行说明。
根据本申请实施例的天线模组，通过使主天线臂111与寄生天线臂121的长度保持一致，可以使得在折叠状态下，主天线单元与寄生天线单元能够尽量保持对称，从而提高电子设备的美观。
根据本申请的一些实施例，在n为偶数且第一主体130与第二主体140为展开状态的情况下，主天线单元和寄生天线单元同向或背离设置。
在该实施例中，当n为偶数时，即在展开状态下，主天线单元的靠近连接组件150的一端与寄生天线单元靠近连接组件150的一端之间的最短距离为偶数倍的λ/2，此时主天线单元与寄生天线单元内的电流同向，此时展开状态下主天线单元的天线辐射效率较高。
在该情况下，主天线单元和寄生天线单元可以基于第一主体130和第二主体140之间的连接组件150，轴对称设置；或者，主天线单元和寄生 天线单元可以同向设置。
根据本申请实施例的天线模组，通过将n设置为偶数，以保证电子设备在展开状态下，主天线单元与寄生天线单元内部的电流方向同向，从而能够提高展开状态下的主天线单元的天线辐射效率。
下面从两个实现角度，对设置方式进行具体说明。
其一、开缝设于两端
如图1和图3所示，根据本申请的一些实施例，主天线单元设有第一开缝161，寄生天线单元设有第二开缝162；
第一开缝161设于主天线臂111的一端，且主天线单元的第一开缝161至第一回地端112的距离为λ/4；
第二开缝162设于寄生天线臂121的一端，且寄生天线单元的第二开缝162至第二回地端122的距离为λ/4；
在该实施例中，主天线单元包括第一开缝161，寄生天线单元包括第二开缝162。
主天线臂111的一端与第一主体130连接，另一端与第一主体130之间形成第一开缝161；寄生天线臂121的一端与第二主体140连接，另一端与第二主体140之间形成第二开缝162。
主天线单元包括第一回地端112，寄生天线单元包括第二回地端122。
其中，主天线单元的第一开缝161至第一回地端112的距离为λ/4，也即主天线臂111的长度为λ/4；寄生天线单元的第二开缝162至第二回地端122的距离为λ/4，也即寄生天线臂121的长度为λ/4。
如图1所示，在一些实施例中，在主天线单元与寄生天线单元背离设置的情况下，在展开状态下，第一回地端112与第二回地端122沿连接组件150轴对称设置，第一开缝161与第二开缝162沿连接组件150轴对称设置；主天线单元的第一回地端112与寄生天线单元的第二回地端122之间的最短距离为偶数倍的λ/2。
具体地，在展开状态下，第一回地端112与第二回地端122距连接组 件150的轴线的距离相等，均为(nλ)/4；第一开缝161至第二开缝162之间的距离为(λ/4+(nλ)/4+λ/4)；其中，n为偶数。
位于第一主体130的主天线臂111激励起从第一开缝161到第一回地端112的四分之一的IFA模，地电流通过连接组件150传输到第二主体140的寄生天线臂121，经过λ/2的偶数倍距离之后，在寄生天线臂121激励起同向电流，从而提升天线效率。
如图3所示，在另一些实施例中，在主天线单元与寄生天线单元同向设置的情况下，在展开状态下，主天线单元中的第一回地端112至第一开缝161的方向，与寄生天线单元中的第二回地端122至第二开缝162的方向保持一致；
具体地，在展开状态下，主天线单元的第一回地端112与寄生天线单元的第二开缝162之间的最短距离为偶数倍的λ/2；第一回地端112距连接组件150的轴线的距离为(nλ)/4，且主天线臂111和寄生天线臂121的长度均为λ/4。
其二、开缝设于中间
如图2所示，根据本申请的一些实施例，主天线单元设有第一开缝161，寄生天线单元设有第二开缝162；第一开缝161设于主天线臂111的中间；第二开缝162设于寄生天线臂121的中间。
在该实施例中，在展开状态下，主天线单元与寄生天线单元背离设置，展开状态下，第一回地端112与第二回地端122沿连接组件150轴对称设置，第一开缝161与第二开缝162沿连接组件150轴对称设置；第一回地端112与第二回地端122之间的距离为(nλ)/2，其中，n为偶数；且包含有第一开缝161的主天线臂111总长为λ/2，包含有第二开缝162的寄生天线臂121总长为λ/2。
根据本申请实施例的天线模组，通过提供多种主天线单元以及寄生天线单元的设置方式，使得用户能够基于实际需求灵活选择最佳的设计方式，在提高电子设备在展开状态或折叠状态下的主天线单元的天线辐射效率的 同时，还能提高灵活性以及可用性。
如图4所示，根据本申请的一些实施例，在n为奇数且第一主体130与第二主体140为展开状态的情况下，主天线单元和寄生天线单元背离设置。
在该实施例中，当n为奇数时，即在展开状态下，主天线单元的靠近连接组件150的一端与寄生天线单元靠近连接组件150的一端之间的最短距离为奇数倍的λ/2，此时主天线单元与寄生天线单元内的电流反向，而在折叠状态下天线单元与寄生天线单元内的电流同向，此时折叠状态下主天线单元的天线辐射效率较高。
在n为奇数时，在展开状态下，主天线单元和寄生天线单元可以基于第一主体130和第二主体140之间的连接组件150，轴对称设置，主天线单元的第一回地端112与寄生天线单元的第二回地端122之间的最短距离为奇数倍的λ/2。
例如，在展开状态下，第一回地端112与第二回地端122距连接组件150的轴线的距离相等，均为(nλ)/4；第一开缝161至第二开缝162之间的距离为(λ/4+(nλ)/4+λ/4)；其中，n为奇数。
其中，主天线单元的第一开缝161至第一回地端112的距离为λ/4，也即主天线臂111的长度为λ/4；寄生天线单元的第二开缝162至第二回地端122的距离为λ/4，也即寄生天线臂121的长度为λ/4。
根据本申请实施例的天线模组，通过将n设置为奇数，以保证电子设备在折叠状态下，主天线单元与寄生天线单元内部的电流方向同向，从而能够提高折叠状态下的主天线单元的天线辐射效率。
如图6和图7所示，根据本申请的一些实施例，寄生天线单元可以包括：第一频率调节组件123和第三电阻R3。
在该实施例中，第一频率调节组件123用于实现多频效果。
多频效果包括：高频和低频。
第一频率调节组件123设于寄生天线臂121且与寄生天线臂121电连 接。
如图8所示，第一频率调节组件123可以包括：第一电阻R1、第二电阻R2、第一开关K1以及第一匹配网络模块129；其中，第一电阻R1与第二电阻R2并联后一端接地，另一端经过第一开关K1与第一匹配网络模块129串联。
第一匹配网络模块129一端经第三电阻R3接地，另一端与寄生天线臂121电连接。
其中，第三电阻R3的阻值可以为50Ω或其他阻值。
第一开关K1与电阻等元器件可以为任意满足天线功能的型号。
当然，在其他实施例中，第一频率调节组件123的拓扑结构还可以为其他任意天线可用的形式，本申请不作限定。
根据本申请实施例的天线模组，通过设置第一频率调节组件123，无需新增射频通路，只需新增与主天线单元的匹配网络或调谐网络拓扑一致的器件(如容、电感以及开关器件)即可实现多频效果，在提高电子设备的使用性能的同时，还能有效节约成本。
根据本申请的一些实施例，主天线单元可以包括：第二频率调节组件113和射频电路118。
在该实施例中，第二频率调节组件113用于调节主天线单元的工作波长，且第二频率调节组件113与第一频率调节组件123对应设置。
第二频率调节组件113设于主天线臂111且与主天线臂111电连接。
第二频率调节组件113与第一频率调节组件123结构类似。
如图9所示，第二频率调节组件113可以包括：第四电阻R4、第五电阻R5、第二开关K2以及第二匹配网络模块119。
第四电阻R4和第五电阻R5并联后一端接地，另一端经第二开关K2与第二匹配网络模块119串联。
第二匹配网络模块119一端与射频电路118连接，另一端与主天线臂111电连接。
通过调节第二频率调节组件113，可以改变主天线单元的工作频率，进而改变主天线单元的工作波长。
其中，主天线单元的工作频率包括高频和低频。
根据本申请实施例的天线模组，通过设置第二频率调节组件113以实现多频效果，既能提高电子设备的使用性能，也能节约成本。
根据本申请的一些实施例，
在主天线单元工作于低频状态，且第一主体130与第二主体140为展开状态的情况下，目标工作波长为主天线单元工作于低频状态下的工作波长；
在主天线单元工作于高频状态，且第一主体130与第二主体140为展开状态的情况下，目标工作波长为主天线单元工作于低频状态下的工作波长。
在该实施例中，主天线单元工作于低频状态下的工作波长为λ1；主天线单元工作于高频状态下的工作波长为λ2。
需要说明的是，在电子设备具有多频效果的情况下，无论主天线单元工作于低频状态还是工作于高频状态，在展开状态下，主天线单元靠近连接组件150的一端与寄生天线单元靠近连接组件150的一端之间的距离均为(nλ)/2，其中，λ＝λ1，λ为目标工作波长，且目标工作波长为主天线单元工作于低频状态下的工作波长λ1。
在展开状态下，主天线单元的馈电端114与寄生天线单元的第一频率调节组件123之间的距离为(nλ2)/2；其中，λ2为主天线单元工作于高频状态下的工作波长。
如图7所示，在一些实施例中，当n取偶数时，在展开状态下，主天线单元与寄生天线单元的电流方向一致，均为逆时针方向，使得展开状态下主天线单元的天线辐射效率提升。
如图6所示，在另一些实施例中，当n取奇数时，在展开状态下，主天线单元与寄生天线单元的电流方向相反，其中主天线单元的电流方向为 逆时针方向，寄生天线单元的电流方向为顺时针方向；而在折叠状态下，主天线单元与寄生天线单元的电流方向相同，从而使得折叠状态下主天线单元的天线辐射效率提升。
在另一些实施例中，在电子设备仅具有单频效果的情况下，则目标工作波长即为主天线单元的实际工作波长。
根据本申请实施例的天线模组，通过在多频模式下对n取不同的数值，在提供多频效果以拓宽电子设备的应用场景，提高电子设备性能的基础上，还能使得用户基于实际需求选择不同的n值以对应提升展开状态或折叠状态下的天线辐射效率，从而进一步提高电子设备的性能。
继续参考图6和图7，根据本申请的一些实施例，主天线单元设有第一开缝161，寄生天线单元设有第二开缝162，第一开缝161设于主天线单元的一端，第二开缝162设于寄生天线单元的一端，且在展开状态下，主天线单元和寄生天线单元背离设置。
在该实施例中，在主天线单元工作于低频状态，对应的工作波长为λ1，且第一主体130与第二主体140为展开状态的情况下，模式为开缝到回地端的四分一IFA模，即主天线臂111长和寄生天线臂121长均为λ1/4，第一回地端112与第二回地端122之间的距离为(nλ1)/2，其中，λ1为主天线单元工作于低频状态下的工作波长；
在主天线单元工作于高频状态，且第一主体130与第二主体140为展开状态的情况下，第一回地端112与第二回地端122之间的距离为(nλ1)/2，其中，λ1为主天线单元工作于低频状态下的工作波长；馈电端114与寄生天线单元的第一频率调节组件123之间的距离为(nλ2)/2；模式为开缝到馈电端的四分一monopole模，即第一开缝161与馈电端114之间的距离为λ2/4，第二开缝162与第一频率调节组件123之间的距离为λ2/4；其中，λ2为主天线单元工作于高频状态下的工作波长。
当然，在其他实施例中，在主天线单元工作于高频状态，且第一主体130与第二主体140为展开状态的情况下，也可以激励起四分之一的IFA 模，本申请不作限定。
在一些实施例中，当n取偶数时，在展开状态下，主天线单元与寄生天线单元的电流方向一致，如图7所示，使得展开状态下主天线单元的天线辐射效率提升。
在另一些实施例中，当n取奇数时，在展开状态下，主天线单元与寄生天线单元的电流方向相反，如图6所示；而在折叠状态下，主天线单元与寄生天线单元的电流方向相同，通过地电流激励来减弱空间耦合激励带来的反向电流强度，以提升折叠状态下主天线单元的天线辐射效率。
根据本申请实施例的天线模组，在高频模式下，通过将馈电端114与寄生天线单元的第一频率调节组件123之间的距离设置为(nλ2)/2，且将第一开缝161与馈电端114之间的距离设置为λ2/4，将第二开缝162与第一频率调节组件123之间的距离设置为λ2/4，使得在n为偶数时，展开状态下主天线单元与寄生天线单元中的电流同向，而在n为奇数时，折叠状态下主天线单元与寄生天线单元中的电流同向，从而通过控制低电流激励以提高展开状态或折叠状态下的天线的辐射效率。
下面对本申请提供的电子设备进行说明。
该电子设备可以为移动电子设备，如手机、平板电脑、手表、车载终端、以及可穿戴智能终端；或者也可以为非移动电子设备，如PC端等。
根据本申请一些实施例的电子设备，包括：第一主体、第二主体和如上任意实施例所述的天线模组。
其中，第一主体和第二主体通过连接组件连接，且第一主体与第二主体在展开状态和折叠状态之间可切换。
天线模组设置于第一主体和第二主体。
根据本申请实施例的电子设备，通过在电子设备中集成天线模组，并将天线模组中主天线单元与寄生天线单元之间的距离设置为(nλ)/2，基于实际需求选择n的奇偶性，以基于实际需求调节展开状态下的主天线单元与寄生天线单元中的电流的方向，从而选择性地提升电子设备在展开状 态下的主天线单元的天线辐射效率或者在折叠状态下的主天线单元的天线辐射效率，具有较高的灵活性和可用性，且硬件结构简单，无需增加额外的元器件，具有较低的设计成本。
在一些实施例中，继续参考图5，该电子设备还可以包括装饰圈190，其中装饰圈190设置于第一主体130的一面。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
尽管已经示出和描述了本申请的实施例，本领域的普通技术人员可以理解：在不脱离本申请的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本申请的范围由权利要求及其等同物限定。
