  • Electromagnetic coupling Also known as mutual inductance coupling, it is a phenomenon in which the current change of one circuit affects the other circuit through mutual inductance due to the mutual inductance between two circuits. When there is close coordination and mutual influence between the input and output of two or more circuit elements or electrical networks, energy will be transmitted from one side to the other through the interaction.

附图说明
为了更清楚地说明本公开实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本公开的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合附图对本公开实施方式作进一步地详细描述。
首先，对本申请实施例中涉及的名词进行简单的介绍：
电磁耦合：又称互感耦合，是由于两个电路之间存在互感，一个电路的电流变化通过互感影响到另一个电路的现象。两个或两个以上的电路元件或电网络的输入和输出之间存在紧密配合与相互影响时，会通过相互作用从一侧向另一侧进行能量的传输。当距离相近的两组天线同时工作时，两组天线之间也会因为互感现象相互产生影响，即相互产生对于对方的电磁干扰。
天线隔离度：被用来定量表示天线之间的电磁耦合的强弱程度，被定义为一组天线发射功率与另一天线接收功率之比，单位为dB。当天线的隔离度较低时，即表示两组天线之间易产生电磁干扰，相互影响传输效率。在现在的通讯终端中，一般需要保证同一终端内的两条天线的隔离度小于或等于-15dB。
图1示出了相关技术中天线的示意图，请参考图1，以该天线实现为LCP天线为例进行说明，如图1所示，该LCP天线101上包括天线单元102、天线单元103、天线单元104。可选地，该LCP天线101上的排布空间较为紧密，故天线单元的设置也较为紧密，天线单元之间的距离较小。
图2示出了相关技术中两组天线之间产生的电磁耦合现象的理论示意 图，请参考图2，天线202与天线203之间的距离较小，所以会产生较强的电磁耦合现象。在天线202与天线203之间发生电磁耦合时，因为天线202与天线203均为带电工作状态，故天线202与天线203之间均带有电流。示例性地，当天线202与天线203同时进行带电工作时，因为其中工作状态下天线中电流不恒定的原因，二者易产生互感现象。此时，天线202和天线203发出的信号相互干涉，会产生表面波电流。表面波电流会对天线202以及天线203的正常工作产生进一步影响。
图3示出了本公开一个示意性实施例提供的天线300的示意图，该天线300包括：相邻排布的第一天线单元310和第二天线单元320；
其中，该第一天线单元310中包括第一天线枝节311和第一寄生枝节312，第二天线单元320包括第二天线枝节321；第一寄生枝节312位于第一天线枝节311和第二天线枝节321之间，且该第一寄生枝节312呈类L型，该第一寄生枝节312包括第一枝节段313和第二枝节段314，第一枝节段313的第一端与接地区域接触，第一枝节段313的第二端与第二枝节段314的第一端衔接，第二枝节段314的第二端指向第二天线枝节321。
可选地，上述第一枝节段313和第二枝节段314可以实现为指向两个方向的枝节整体，也可以实现为两个分离并衔接的枝节段。
可选地，由于上述第一寄生枝节312呈类L型，故该第一寄生枝节312中可以仅由该第一枝节段313和第二枝节段314组成，也可以由第一枝节段313、第二枝节段314和另一枝节段组成，其中，另一枝节段与第二枝节段314衔接。
可选地，如图3所示，该第一天线枝节311和第二天线枝节321呈类L型，且该第一天线枝节311和第二天线枝节321的走线相反，也即，该第一天线枝节311的L型指向该第二天线枝节321的反方向，而第二天线枝节321的L型指向该第一天线枝节311的反方向。
可选地，上述第一天线单元310和第二天线单元320实现的频段同频；或，该第一天线单元310和第二天线单元320实现的频段中存在同频频段；或，上述第一天线单元310和第二天线单元320实现的频段中存在频段差小于要求频段差的频段。
可选地，上述第一寄生枝节312实现为第一天线单元310的一部分， 故在特定环境下特定的波长可以形成特定的谐振，从而该第一寄生枝节312可以在特定频段进行辐射，实现信号的收发。
可选地，本公开实施例中以上述第一天线单元310和第二天线单元320设置于工业化液晶聚合物(Liquid Crystal Polymer，LCP)材料上为例进行说明，也即，上述第一天线单元310和第二天线单元320设置于LCP板上。
可选地，该第一天线单元310和第二天线单元320也可以采用激光直接成型技术(Laser Direct Structuring，LDS)设置于终端中框上；或，该第一天线单元310和第二天线单元320可以设置于柔性电路板(Flexible Printed Circuit，FPC)上或改性聚酰亚胺(Modified PI，MPI)上，本申请实施例对该第一天线单元310和第二天线单元320的设置不加以限定。
可选地，上述接地区域内覆盖有导体材料，或，上述接地区域由导体材料构成。
以第一天线单元310和第二天线单元320设置于LCP天线上为例，对本公开实施例提供的天线的工作原理进行阐述：
第一天线单元310和第二天线单元320设置于LCP板上，由于LCP板上可实现多支天线单元，而多支天线单元紧密相邻，当第一天线单元310和第二天线单元320实现的频段同频，或实现的频段中包括同频频段，或实现的频段中存在频率相近时，该第一天线单元310和第二天线单元320之间产生的表面波影响两个天线单元的射频工作。可选地，第一天线单元310与第二天线单元320需要与其他终端部件进行线路连接，以保证第一天线单元310和第二天线单元320可以正常上电。第一天线单元310中的第一寄生枝节312设置于第一天线枝节311和第二天线枝节321之间，该第一寄生枝节312呈类L型，由第一枝节段313和第二枝节段314构成该类L型，且第一枝节段313接地，第二枝节段314指向该第二天线枝节321，当第一天线枝节311和第二天线枝节321之间因信号干涉产生表面波时，第一天线枝节311和第二天线枝节321对第一寄生枝节312激励出反向电流，使表面波相互抵消从而降低隔离度。
综上所述，本实施例提供的天线，通过将天线单元分解为天线枝节和寄生枝节，并将寄生枝节设置为类L型置于相邻两个天线枝节之间，从而使两个天线枝节对寄生枝节激励出反向电流，从而抵消表面波，降低天线 单元之间的电磁耦合，降低天线单元之间的隔离度，提高天线单元的工作准确度。

综上所述，本实施例提供的天线，通过将天线单元分解为天线枝节和寄生枝节，并将寄生枝节设置为类L型置于相邻两个天线枝节之间，从而使两个天线枝节对寄生枝节激励出反向电流，从而抵消表面波，降低天线 单元之间的电磁耦合，降低天线单元之间的隔离度，提高天线单元的工作准确度。
