具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
现有技术中，在全面屏移动通信设备中，与具有16：9的显示比率的传统设备相比，天线设计起来要困难得多，这主要是因为设备的显示器始终由金属板支撑，并且当屏幕尺寸延长时，天线间隙必须减小，这种减小自然会降低天线辐射能力。因此，到目前为止，在具有整体全面显示屏的移动通信设备中，存在诸如单极，偶极，环路，槽等的传统天线类型，天线间隙可以仅在半维空间中定义，并且辐射场可以仅在半空间方向上扩展并且具有有限的辐射性能，甚至在需要多频带操作时，必须限制天线高度以使手机保持相当薄，本发明公开了用于这种全面屏移动通信设备的新的天线设计方法。下面通过几个具体实施例对该方案进行详细说明。
图1是根据一示例性实施例示出的一种移动通信设备实施例一的结构示意图，如图1所示，该移动通信设备具有天线，可进行无线通讯，例如：手机、通话平板、可穿戴智能设备等。在该新型的移动通信设备10中具体包括：
缝隙天线、电路板、电源模块、设备壳体3；
移动通信设备10中的缝隙天线可以用来支持任何可能的通信频带。例如，移动通信设备10可以用于支持局域网通信、语音和数据蜂窝电话通信、全球定位系统(GPS)通信或者其它卫星导航系统通信等的天线结构。

在一种具体的实现方式中，移动通信设备10还包括：
显示屏4和设备后壳。
具体的，显示屏4可以是全面屏也可以是其他屏幕，显示器4可以是具有电容性触摸电极的触摸屏；显示器4可以包括发光二极管(LED)、有机发光二极管(Organic Light-Emitting Diode,OLED)、等离子、薄膜式晶体管(Thin Film Transistor；TFT)、液晶显示器(LCD)部件或者其它合适的显示器件；
