技术领域
本发明涉及天线技术领域，具体而言，涉及一种具备解耦合功能的天线组件、一种解耦合方法和一种解耦合系统。
背景技术
在相关技术中，终端设备上通常设置多个天线，分别用于收发不同频率的信号，为了降低多个天线在收发信号过程中的耦合频率，通常采用寄生天线、栅格金属主地和解耦合器件等方案来实现解耦合过程，但是，相关的解耦合方案存在如下缺点：
(1)寄生天线方案：将会多出一个天线来专门解耦合，对于天线净空有限的小型移动终端来讲，很难给出寄生天线的空间，并且只能实现窄带解耦合；
(2)栅格金属主地方案：对接地进行栅格化，但是对于手机等小型化终端来说，金属主地上有较多金属器件，不可能全部开槽；
(3)解耦合器件方案：较难做成宽带全频段解耦合，尤其是现阶段LTE的频段较宽，解耦合器件实际上较难覆盖整个LTE频段
因此，如何设计一种宽频带可调的解耦合天线组件成为亟待解决的技术问题。
