Description

一种终端 技术领域

背景技术
随着电子产品的不断发展，用户在挑选手机时，不仅注重手机的通话性能，也越来越关心手机的美观性，尤其是用户追求的低调而奢华的消费理念，使得金属质感的物品受到年青一代用户的追捧。但是全金属外壳会造成手机信号溢出困难，因此三段式金属外壳已经成为了手机外观设计的潮流。
当前技术中，三段式金属外壳的上端设置有非导电断缝区域，为了保证天线净空区的面积，达到良好的信号溢出，通常将非导电断缝区域设置在距手机上端较远的位置，例如，距离上端5mm到15mm之间，因此影响了外壳金属一体化的观感。为了进一步提升手机的外观，使手机外壳更加趋于金属一体化，可以将非导电断缝区域尽可能向上端移动，但这样做会造成上端金属区域变窄，导致天线净空区缩小，进而影响手机的信号强度，而手机信号不佳还可能给用户造成巨大的经济损失，用户体验较差。

图1为实现本发明各个实施例的移动终端的硬件结构示意。
移动终端100可以包括无线通信单元110和电源单元190等等。图1示出了具有各种组件的移动终端，但是应理解的是，并不要求实施所有示出的组件。可以替代地实施更多或更少的组件。将在下面详细描述移动终端的元件。
无线通信单元110通常包括一个或多个组件，其允许移动终端100与无线通信系统或网络之间的无线电通信。例如，无线通信单元可以包括广播接收模块111、移动通信模块112、无线互联网模块113、短程通信模块114和位置信息模块115中的至少一个。

实施例一
本发明实施例提供一种终端20，所述终端20可以为手机，平板电脑或其他需要设置天线的设备，本发明实施例以手机为例进行说明。如图2所示，所述终端20包括：设置有天线辐射区2011的中框201、设置有非导电 断缝区域2021的金属背板202，全球定位系统(Global Positioning System，GPS)/无线保真(Wireless-Fidelity，WIFI)天线的馈电端口203，第一匹配/调谐电路204和接地点205。
其中，所述金属背板202与所述中框201扣合，所述天线辐射区2011与所述非导电断缝区域2021紧密接触。所述天线辐射区2011包括第一辐射区2011a和第二辐射区2011b，所述GPS/WIFI天线的馈电端口203设置在所述第一辐射区2011a，所述第一辐射区2011a用于对所述GPS/WIFI天线的信号进行辐射。所述第一匹配/调谐电路204设置在所述金属背板202上，用于对进入所述GPS/WIFI天线的馈电端口203的信号进行匹配和/或调谐。所述接地点205设置在所述第一辐射区2011a与所述第二辐射区2011b之间，用于连接所述天线辐射区2011与所述金属背板202。
示例的，所述中框为手机侧面的一圈边框，介于屏幕和后壳之间，通常设置有音量键，锁屏键，耳机插孔和电源插孔等。天线辐射区2011可以设置在中框201的任意一个边上，本发明实施例以天线辐射区2011设置在中框201靠近听筒的顶边上为例进行说明。本发明实施例中的手机后壳为金属背板202，为了尽量实现手机后壳的金属一体化的观感，需要在金属背板202与中框201扣合时，使得天线辐射区2011与非导电断缝区域2021紧密接触，此时非导电断缝区域2021位于金属背板202上最靠近天线辐射区2011的顶端。当用户观察手机后壳时，看到的是整面金属背板202，其顶端设置的非导电断缝区域2021由于非常接近天线辐射区2011，基本可以被忽略，最大限度的提高了手机后壳的金属一体化的观感。
将非导电断缝区域2021设置在金属背板202的顶端，导致天线净空区较小，影响了现有天线的性能。但是影响天线性能的参数有很多，天线的馈电端口以及接地点的位置，都会对天线的性能产生较大的影响，因此可以通过对天线的馈电端口和接地点位置的调整，改善天线的性能。通常手 机顶端会设置GPS/WIFI天线，即同一个天线既可以用于GPS信号的收发，也可以用于WIFI信号的收发。在其他实施方式中，可以将天线辐射区2011分为第一辐射区2011a和第二辐射区2011b，其中第一辐射区2011a用于对GPS/WIFI天线的信号进行辐射，将GPS/WIFI天线的馈电端口204设置在第一辐射区2011a内，将接地点205设置在第一辐射区2011a和第二辐射区2011b之间，用于实现第一辐射区2011a和第二辐射区2011b的接地。
这样一来，由于天线辐射区设置在中框上，并分为两个辐射区，GPS/WIFI天线的馈电端口设置在对GPS/WIFI天线的信号进行辐射的第一辐射区，使得在天线净空区较小的情况下，仍然能够保证GPS或WIFI信号的辐射功率，进而保证了GPS/WIFI天线的性能，同时由于金属背板与中框扣合时，天线辐射区与非导电断缝区域紧密接触，即非导电断缝区域位于终端外壳的顶端，最大限度的实现了终端外壳的金属一体化，提高了用户体验。
在一实施方式中，如图3所示，所述终端20还包括分集天线的馈电端口206和第二匹配/调谐电路207。其中，所述分集天线的馈电端口206设置在所述第二辐射区2011b，所述第二辐射区2011b用于对所述分集天线的信号进行辐射。所述第二匹配/调谐电路207设置在所述金属背板202上，用于对进入所述分集天线的馈电端口206的信号进行匹配和/或调谐。
示例的，手机中除了设置在底部的中心天线之外，还可以在顶部设置分集天线，当中心天线的性能难以满足用户需求时，可以通过分集天线辅助实现性能增强。具体的，在天线净空区较小的情况下，可以将天线辐射区2011的第二辐射区2011b作为分集天线的辐射区，并将分集天线的馈电端口206设置在第二辐射区2011b内，使得分集天线的性能能够满足用户需求。
在一实施方式中，如图4所示，所述终端20还包括开关电路208和控 制器209，所述控制器209分别与所述开关电路208和所述第二匹配/调谐电路207连接。所述开关电路208设置在所述第二辐射区2011b，并与所述金属背板202连接；所述控制器209用于控制在所述开关电路208处于开启状态或关闭状态时，所述分集天线实现不同的带宽覆盖。
示例的，手机的天线需要能够实现4G和2G的带宽覆盖。如果手机接入4G网络，则不需使用2G信号，如果手机接入2G网络，则不需使用4G信号，因此实际应用中4G网络和2G网络是交替使用的，为了实现4G网络和2G网络的交替覆盖，可以设置开关电路208，开关电路208处于开启状态和处于关闭状态，分别对应不同的带宽覆盖。
在一实施方式中，所述控制器209具体用于：根据所述终端20当前的工作频率，确定是否开启所述开关电路208；当确定开启所述开关电路208时，调整所述第二匹配/调谐电路207，使得所述分集天线实现第四代移动通信技术(4rd-Generation，4G)网络的带宽覆盖；当确定关闭所述开关电路208时，调整所述第二匹配/调谐电路207，使得所述分集天线实现第二代移动通信技术(2nd-Generation，2G)网络的带宽覆盖。
示例的，当分集天线工作时，GPS和WIFI天线相当于50欧姆负载端，即分集天线与GPS和WIFI天线的相互独立工作的，互不影响。当控制器209确定当前手机的工作频率处于4G网络时，可以控制开关电路208开启，使得第二辐射区2011b与金属背板202连接，开关电路208输出第一电感值，控制器209在检测到第一电感值之后，调整第二匹配/调谐电路207，使得分集天线实现1710-2700MHz的带宽覆盖，即实现4G网络的带宽覆盖；当控制器209确定当前手机的工作频率处于2G网络时，可以控制开关电路208关闭，使得第二辐射区2011b与金属背板202断开，开关电路208输出第二电感值，控制器209在检测到第二电感值之后，调整第二匹配/调谐电路207，使得分集天线实现824-960MHz的带宽覆盖，即实现2G网络的带 宽覆盖。其中，所述第一电感值与所述第二电感值不同。
在一实施方式中，如图5所示，控制器209与所述第一匹配/调谐电路204电连接；所述控制器209还用于：根据所述终端20当前的工作频率，调整所述第一匹配/调谐电路204，使得所述GPS/WIFI天线同时实现GPS网络和WIFI网络的双频覆盖。
示例的，当GPS和WIFI天线工作时，分集天线相当于50欧姆负载端，当控制器209确定手机当前正在使用GPS或WIFI时，可以调节第一匹配/调谐电路204中的电感值和电容值，使得手机可以同时实现1520-1680MHz和2400-2500MHz的双频覆盖，即实现GPS和WIFI的通信需求。
在一实施方式中，如图6所示，所述天线辐射区2011设置在所述中框201的第一边框201a，所述第一边框201a为所述中框201靠近所述终端20听筒一侧的边框，且所述天线辐射区2011与所述中框201的第二边框201b和第三边框201c断开，所述第二边框201b和所述第三边框201c与所述第一边框201a垂直。
示例的，中框201总共有四个边框，其中靠近手机听筒的边框为第一边框201a，天线辐射区2011设置在所述第一边框201a上，实际应用中，可以使用整个第一边框201a作为天线辐射区2011，也可以使用部分第一边框201a作为天线辐射区2011，本发明实施例对此不做限定。其中第二边框201b和第三边框201c与第一边框201a垂直，为了保证天线信号的正常溢出，天线辐射区2011需要与第二边框201b和第三边框201c断开。
在一实施方式中，如图7所示，所述天线辐射区2011的第一辐射区2011a具有向所述第二边框201b弯曲的第一弯曲部2011ai；所述天线辐射区2011的第二辐射区2011b具有向所述第三边框201c弯曲的第二弯曲部2011bi。
示例的，为了达到更好的辐射效果，可以在天线辐射区2011的两端设 置弯曲部，弯曲部覆盖手机的两个顶点，增大了辐射区的面积。
在一实施方式中，如图8所示，所述非导电断缝区域2021的第一端具有与所述第一弯曲部2011ai弧度相同的第三弯曲部2021i；所述非导电断缝区域2021的第二端具有与所述第二弯曲部2011bi弧度相同的第四弯曲部2021j。
示例的，为了更进一步的提高手机外壳金属一体化的观感，在视觉方面进一步减小了其宽度，可以将非导电断缝区域2021设置为具有弧度的形状，具体的，可以在非导电断缝区域2021设置与第一弯曲部2011ai弧度相同的第三弯曲部2021i和与第二弯曲部2011bi弧度相同的第四弯曲部2021j。
在一实施方式中，所述非导电断缝区域2021在所述金属背板202上的宽度大于或等于1mm(毫米)，小于或等于2mm。
示例的，由于设置在金属背板201上的非导电断缝区域2021的宽度仅有1-2mm，因此用户在查看手机的金属背板时，可以基本忽略顶端的非导电断缝区域2021，最大限度的实现了金属一体化的观感。示例的，假设第一边框201a厚度为0.6mm，垂直于纸面方向的高度为5mm，其作为天线辐射区2011的有效长度为86mm，非导电断缝区域2021宽度为1.5mm，第二边框201b和第三边框201c垂直于纸面方向的高度为5mm，金属背板201的长为138mm，宽为71mm，厚度为0.3mm，此时从背面看整个金属背板201的金属占比高达95％。
在一实施方式中，所述接地点205至所述分集天线的馈电端口206之间的距离大于或等于所述接地点205至所述GPS/WIFI天线的馈电端口203之间的距离。在一实施方式中，所述接地点205至所述分集天线的馈电端口206之间的距离与所述接地点205至所述GPS/WIFI天线的馈电端口203之间的距离的比值大于或等于2。
