本申请主张在2017年12月29日在中国提交的中国专利申请No.201711482114.4的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信应用的技术领域，尤其涉及一种无线移动终端及天线。
背景技术
由于5G(第五代移动通信)的脚步日益接近，故5G相关的天线需求便日益旺盛与受到瞩目，其中，对终端天线设计最具挑战性与新颖性的便是毫米波的天线阵列设计。而为了有更好的天线辐射空间覆盖，毫米波天线阵列往往会由辐射方向图互补(如尾焰式或称为端射(end-fire)与宽边辐射(broadside))的天线单元所组成，且为了克服毫米波高频的路径损耗，毫米波天线阵列在空间中的各方向的辐射波瓣上都希望有较好的增益以达到更佳的无线传输距离。故在足够增益之下，同时具有理想的辐射波瓣覆盖对毫米波天线设计是个重要的研究课题。
全球的5G毫米波常用频段基本有两区段，一个是26.5GHz到29.5GHz的毫米波低频频率区段，另一个是37GHz到42.5GHz的毫米波高频频率区段。故在上述的无线传输距离与空间覆盖的考量下，若要漫游全球5G毫米波频段，则需支持上述两毫米波频段。而5G毫米波天线阵列目前主流方案为透过系统封装(system in package，SiP)的方式，形成天线封装(Antenna in Package，AiP)，即毫米波天线阵列与射频芯片封装成一模块。
目前传统的5G毫米波天线阵列AiP模块中的尾焰式天线，往往由无源引向器(director)加上形状为平面且平直式的反射器(reflector)的准八木天线(quasi-Yagi Uda antenna)所形成，因缺少标准八木天线的引向器，而其辐射波瓣往往较窄，造成无线覆盖较窄，且在频段上往往只支持单一毫米波频率，无法全球漫游，而影响到用户无线体验与产品竞争力。

具体实施方式
本公开的目的在于提供一种无线移动终端及天线，用以解决相关技术中尾焰式天线辐射波瓣往往较窄，造成无线覆盖较窄，且仅支持单一毫米波频率的问题。
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合具体实施例及附图进行详细描述。
在本公开的一些实施例中，提供了一种天线，如图1至图3所示，包括：
第一天线10，所述第一天线10工作在第一毫米波频段；
第二天线20，所述第二天线20位于所述第一天线10在Y轴正向方向(+Y方向)一侧的第一侧，所述第二天线20工作在第二毫米波频段，所述第二毫米波频段内的频率大于所述第一毫米波频段内的频率；
金属面30，所述金属面设置于所述第一天线10在的远离第二天线的Y轴负向方向(-Y方向)一侧的第二侧的，所述金属面30包括至少一个弯曲边缘31，所述至少一个弯曲边缘31朝所述第一天线10所在的方向弯曲，所述第一天线10位于所述第二天线20和所述弯曲边缘31之间。
本公开实施例的天线，位于第一天线10第二侧的金属面30可作为第一天线10的反射器，位于第一天线10第一侧的第二天线20可同时兼当第一天线10的引向器，故可在复用结构的基础上，增加第一天线10的辐射方向性与增益且有助辐射波瓣的扩展，故可提升第一天线10的无线传输距离与空间无线覆盖的范围；另一方面，第一天线10可作为第二天线20的反射器，故同样地可在复用结构的基础上，增加第二天线20的辐射方向性与增益，而可提升第二天线20的无线传输距离。故此设计，天线可在足够增益之下，扩展了尾焰式天线的辐射波瓣，达到了更广的空间无线覆盖，且支持多频(如双频)毫米波段，可达成全球漫游能力，以有更好的产品竞争力，提高了用户的无线体验。
其中，第一天线10工作在第一毫米波频段，第一毫米波频段如可为低频毫米波，第二天线20工作在第二毫米波频段，第二毫米波频段如可为高频毫米波，此时第一天线10为低频毫米波天线，第二天线20为高频毫米波天线，该天线组成了一组低频与高频的双频尾焰式辐射天线。
可选地，如图1至图3所示，所述弯曲边缘31呈抛物线。
此时，金属面30的弯曲边缘31呈抛物线，抛物线朝第一天线10所在的方向弯曲，金属面30可作为第一天线10的反射器。
具体地，所述弯曲边缘31的顶点与所述弯曲边缘31的焦点之间的距离等于所述弯曲边缘31的顶点与所述第一天线10之间的距离。
此时，弯曲边缘31的顶点与焦点之间的距离等于弯曲边缘31的顶点与 第一天线10之间的距离，提升了天线性能。
可选地，所述第一天线10和所述第二天线20分别包括至少一个金属臂，但不限于此。所述第一天线10的金属臂设置在同一非金属面或设置在不同的非金属面上，所述第二天线20的金属臂设置在同一非金属面或设置在不同的非金属面上。
作为一种可选的实现方式，如图1所示，所述第一天线10的金属臂和所述第二天线20的金属臂设置在同一非金属面100；所述金属面30与所述非金属面100共平面。
此时，金属面30上的至少一个弯曲边缘31位于非金属面100上，金属面30与第一天线10共平面。
进一步地，所述第一天线10和所述第二天线20通过天线馈入线40串联；所述天线还包括：
与所述非金属面100垂直设置的金属板50，所述金属面30与所述第一天线10位于所述金属板50的同一侧，所述金属板50包括非导电区域60，所述天线馈入线40行经所述非导电区域60分别与所述第一天线10和第二天线20连接。
此时，天线馈入线40行经金属板50上的非导电区域60分别与第一天线10和第二天线20连接，第一天线10和第二天线20两毫米波天线经由天线馈入线40串接成一组双频尾焰式辐射的天线。
其中，天线馈入线40具体包括两个天线馈入金属线，两个天线馈入金属线中至少有一个天线馈入金属线不位于所述非金属面100上。当第一天线10和第二天线20分别包括两个金属臂时，第一天线10的第一金属臂和第二天线20的第一金属臂通过第一天线馈入金属线连接，第一天线10的第二金属臂和第二天线20的第二金属臂通过第二天线馈入金属线连接，此时，若第一天线10的第一金属臂和第二天线20的第一金属臂位于非金属面100上，而第一天线10的第二金属臂和第二天线20的第二金属臂位于除非金属面100之外的其他非金属面上，则第一天线馈入金属线位于非金属面100上，第二天线馈入金属线位于其他非金属面上；若第一天线10的第一金属臂和第二金属臂，以及第二天线20的第一金属臂和第二金属臂均位于非金属面100上， 此时，可将第一天线馈入金属线设置于非金属面100上，将第二天线馈入金属线设置于非金属面100的上方，并通过向下穿孔连接至第一天线10的第二金属臂和第二天线20的第二金属臂；若第一天线10的第一金属臂和第二天线20的第一金属臂位于除非金属面100之外的第一非金属面上，以及第一天线10的第二金属臂和第二天线20的第二金属臂位于除非金属面100之外的第二非金属面，此时，第一天线馈入金属线位于第一非金属面上，第二天线馈入金属线位于第二非金属面上。

其中第一天线10和第二天线20分别包括两个金属臂，第一天线10的单臂长为L1，臂宽为W1；而第二天线20的单臂长为L2，臂宽为W2。在第一天线10后方有一金属凸抛物线形墙面，即金属面30，做为是第一天线10的反射器(reflector)，而金属凸抛物线形墙面的凸抛物线的顶点(apex)与第一天线10之间的距离为D1，第一天线10与第二天线20之间的距离为D2；金属凸抛物线形墙面(金属面30)的高度为H。优选地，L1与L2为各自对应频段中间频率的λg/4(即四分之一的导波波长)，而W1与W2范围为0.0001mm到30mm，D1为低频对应频段中间频率的λg/4，而D2为高频对应频段中间频率的λg/4，而凸抛物线则是以D1作为其焦点(focus)与顶点之间的距离进行形状设计，而金属凸抛物线形墙面(金属面30)的高度H可视实际AiP工艺的层厚进行设计，优选地，H的范围为0.0001mm到30mm。当然，此金属面30可向下往-Z方向延伸。
作为另一种可选的实现方式，如图3所示，所述第一天线10的金属臂和所述第二天线20的金属臂设置在与同一非金属面100；所述金属面30与所述非金属面100相交，且所述至少一个弯曲边缘31位于与所述非金属面100垂直的平面上。

其中，天线馈入线40具体可为天线馈入金属线。
下面对本公开实施例的天线的另一具体结构举例说明如下：
如图3所示，本公开实施例的天线包括设置于非金属面100上的第一天线10(低频毫米波天线)和第二天线20(高频毫米波天线)，第二天线20位于第一天线10更为+Y的方向，即在+Y方向上第二天线20位于第一天线10的前方(第一天线10的第一侧)，且第一天线10的后方(第一天线10的第二侧)设置有金属面30，金属面30在与非金属面100垂直的左右两个平面(Y-Z平面)形成两个弯曲边缘31，右侧的弯曲边缘31沿着+X轴延伸成金属面30，金属面30与非金属面100垂直，且弯曲边缘31朝第一天线10所在的方向弯曲，即弯曲边缘31相对于第一天线10呈凸抛物线。金属面30上包括非导电区域60，天线馈入线40行经非导电区域60分别与第一天线10和第二天线20连接。该天线中，位于第一天线10后方的金属面30可作为第一天线10的反射器，位于第一天线10前方的第二天线20可同时兼当第一天线10的引向器，故可在复用结构的基础上，增加第一天线10的辐射方向性与增益且有助辐射波瓣的扩展，故可提升第一天线10的无线传输距离与空间无线覆盖的范围；另一方面，第一天线10可作为第二天线20的反射器，故同样地可在复用结构的基础上，增加第二天线20的辐射方向性与增益，而可提升第二天线20的无线传输距离。
