 本发明的实施方式
下面结合附图和实施方式对本申请作进一步说明。
请一并结合图1至图6，现对本申请提供的移动终端10进行说明。该移动终端10可为手机、笔记本电脑、平板电脑、播放器、耳机、智能手表或智能眼镜等。本实施例中，移动终端10包括中壳100、位于中壳100两侧的前盖200和后盖300，还包括天线组件400。该天线组件400收容于中壳100、前盖200和后盖300围设形成的空间内。
进一步地，天线组件400包括天线单元410和线路板420。天线单元410与线路板420间隔设置。线路板420设置有天线地、射频馈源以及与射频馈源电连接的馈电点。该线路板420为PCB板，可以理解为在其他实施例中，线路板420还可以为FPC板或软硬结合板。本实施例中，天线单元410的第一连接端411与天线地电连接。天线单元410的第二连接端412通过匹配电路与馈电点电连接，其中匹配电路包括一串联的LC电路和一并联的LC电路。
进一步地，串联的LC电路包括并联的电感和电容，并联的LC电路包括串联的电感和电容。
通常，由电感和电容并联的LC电路具有低于自谐振频率表现为感性，高于自谐振频率表现为容性的特点，由电感和电容串联的LC电路具有低于自谐振频率表现为容性，高于自谐振频率表现为感性的特点。
本实施例中，当频率低于谐振频率时，串联的LC电路表现为感性，相当于馈电点与天线单元410的第二连接端412之间串联了一个电感；同时，并联的LC电路表现为容性，相当于馈电点与天线单元410的第二连接端412之间并联了一个电容。可以理解的是，此时天线单元410和馈电点之间相当于串联电感，并联电容。同时电容可以滤除馈电处低频信号中夹杂的少量高频信号，天线的辐射效率进一步得到了提高。
当频率高于谐振频率时，串联的LC电路表现为容性，相当于馈电点与天线单元410的第二连接端412之间串联了一个电容；同时，并联的LC电路表现为感性，相当于馈电点与天线单元410的第二连接端412之间并联了一个电感。可以理解的是，此时天线单元410和馈电点之间相当于串联电容，并联电感。同时电感可以滤处馈电处高频信号中夹杂的少量低频信号，天线的辐射效率进一步得到了提高。
因此，采用匹配电路将天线单元410与馈电点电连接，可使得天线单元410在尺寸大大减小的同时能够具有突出的辐射性能，从而减小了天线单元410的占用面积避免天线间拥挤。本实施例中，天线单元410的尺寸可以缩小至常规PIFA天线原有尺寸的62%，高频辐射特性相对于常规PIFA天线提高了2dB。
本实施例中，天线组件400的工作频率为3400MHz~3600MHz和4800MHz~5000MHz。图4为本申请中天线组件400与常规PIFA天线回波损耗对比图，由图可知，本申请中天线组件400通过采用匹配电路可以使天线单元410既工作于3400MHz~3600MHz，又工作于4800MHz~5000MHz。
图5为本申请中天线组件400与常规PIFA天线的天线效率对比图，由图可知，尽管本实施例的天线单元410尺寸小、净空区域小且与天线地的距离近，但天线组件400在天线单元410的工作频率的两个频段内仍然具有较好的天线效率。具体地，从图中可以看出，在4800MHz~5000MHz频段，天线组件400的辐射效率和总效率明显高于常规PIFA天线，大约相差2dB。在3400MHz~3600MHz频段，天线组件400的辐射效率与常规PIFA天线的辐射效率，存在一个交点频率值，该值约为3455MHz，频率低于3455MHz，天线组件400的辐射效率低于常规PIFA天线辐射效率；频率高于3455MHz，天线单元410的辐射效率高于常规PIFA天线辐射效率。同样，天线组件400的总效率与常规PIFA天线的总效率，存在一个交点频率值，该值约为3500MHz，频率低于3500MHz，天线组件400的总效率低于常规PIFA天线总效率；频率高于3500MHz，天线组件400的总效率高于常规PIFA天线总效率。
本实施例中，天线单元410包括第一辐射体413和第二辐射体414，第一辐射体413与第二辐射体414间隔设置。第一连接端411位于第一辐射体413上，第二连接端412位于第二辐射体414上。
进一步的，第一辐射体413包括第一辐射分支4131和第二辐射分支4132，第二辐射分支4132自第一辐射分支4131的第一端沿第一方向延伸。第二辐射体414包括第三辐射分支4141和第四辐射分支4142。第三辐射分支4141支向靠近第二辐射分支4132方向延伸，第四辐射分支4142自第三辐射分支4141靠近第二辐射分支4132的一端向靠近第一辐射分支4131方向延伸。本实施例中，第一方向平行于图1中X箭头所指方向。
进一步的，第一辐射分支4131与第三辐射分支4141平行设置。第二辐射分支4132与第四辐射分支4142平行设置。
进一步的，第一辐射分支4131与第二辐射分支4132垂直设置。第三辐射分支4141与第四辐射分支4142垂直设置。
进一步地，天线组件400还包括第一连接柱430和第二连接柱440。第一连接端411通过第一连接柱430与天线地电连接。第二连接端412通过第二连接柱440与匹配电路电连接并通过匹配电路与馈电点电连接。
本实施例中，天线单元410可工作于Sub-6G，同时相较常规PIFA天线，天线单元410的尺寸大大减小，辐射性能显著提高，可满足MIMO技术中，在有限的空间内尽可能的放置多组天线，同时保证各天线的性能符合的要求。
以上所述的仅是本申请的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本申请创造构思的前提下，还可以做出改进，但这些均属于本申请的保护范围。
