请参阅图1,本公开实施例提供的天线10包括天线组件11和馈电组件12,其中,馈电组件12与天线组件11连接,以实现向天线组件11中馈入信号。
具体地,天线组件11包括第一天线单元111、第二天线单元112,其中,第一天线单元111和第二天线单元112间隔设置。第一天线单元111包括第一辐射体1111、第一接地枝节1112和第一馈电枝节1113;其中,第一接地枝节1112和第一馈电枝节1113分别与第一辐射体1111连接。第二天线单元112包括第二辐射体1121、第二接地枝节1122和第二馈电枝节1123;其中,第二辐射体1121和第二馈电枝节1123分别与第二辐射体1121连接。馈电组件12包括馈电臂121、第一馈电点122和第二馈电点123;其中,第一馈电点122和第二馈电点123分别设置于馈电臂121,第一馈电点122和第二馈电点123之间具有间距。馈电臂121与第一辐射体1111及第二辐射体1121间隔设置,并与第一馈电枝节1113及所二馈电枝节分别连接。第一辐射体1111和第二辐射体1121之间形成有间隔区110,第一馈电点122对应间隔区110设置于馈电臂121,第二馈电点123设置于馈电臂121与第一馈电枝节1113或与第二馈电枝节1123连接的一端。当外部信号经第一馈电点122或第二馈电点123输入天线10时,外部信号均经第一天线单元111和第二天线单元112向外辐射。本公开实施例的天线10中,第一天线单元111和第二天线单元112具有相似的结构,在相同的谐振频段下工作,通过馈电组件12以及第一天线单元111和第二天线单元112的结构设计,第一天线单元111和第二天线单元112具有良好的隔离度,无论是从第一馈电点122馈电还是从第二馈电点123馈电,第一天线单元111和第二天线单元112都参与工作,第一天线单元111的方向图和第二天线单元112的方向图互补,且第一辐射体1111和第二辐射体1121均向外辐射信号,从而可以在保证天线10具有良好的MIMO性能;此外,由于第一辐射体1111和第二辐射体1121实现共用,因此能节省天线10占据的空间,从而为其他零部件的布局提供更多的空间。
请参阅图1,在一些实施方式中,间隔区110与馈电臂121延伸长度的中心区相对应。间隔区110和馈电臂121的位置关系,可以实现第一天线单元111中的第一辐射体1111和第二天线单元112中的第二辐射体1121的共用,从而可以在保证第一天线单元111和第二天线单元112的隔离度的前提下,有效地提升天线10的辐射性能。
请参阅图1、图2和图3,在一些实施方式中,馈电臂121的延伸长度是天线10谐振波长的奇数倍,即:L=(2n-1)λ,其中,L为馈电臂121的延伸长度;n为正整数,如1或2或3或4等;λ为天线10的谐振波长。这样的结构设计,当从第一馈电点122输入外部信号 时,外部信号在天线10中具有第一传输路径S1和第二传输路径S2,其中,第一传输路径S1的长度为外部信号自第一馈电点122传输至第一辐射体1111靠近第二辐射体1121的端部所经过的路程,第二传输路径S2的长度为外部信号自第一馈电点122传输至第二辐射体1121靠近第一辐射体1111的端部所经过的路程,那么,第一传输路径S1的长度和第二传输路径S2的长度相同,此时,可以实现第一辐射体1111中的电流方向和第二辐射体1121中的电流方向相反。当从第二馈电点123输入外部信号时,外部信号在天线10中具有第三传输路径S3和第四传输路径S4,其中,第三传输路径S3的长度为外部信号自第二馈电点123经馈电臂121传输至第一辐射体1111靠近第二辐射体1121的端部所经过的路程,第四传输路径S4的长度为自第二馈电点123传输至第二辐射体1121靠近第一辐射体1111的端部所经过的路程;或者,第三传输路径S3的长度为外部信号自第二馈电点123经馈电臂121传输至第二辐射体1121靠近第一辐射体1111的端部所经过的路程,第四传输路径S4的长度为自第二馈电点123传输至第一辐射体1111靠近第二辐射体1121的端部所经过的路程,由于第三传输路径S3要经过整个馈电臂121的延伸长度,而馈电臂121的延伸长度设计为天线10谐振波长的奇数倍,所以此时第一辐射体1111的电流方向和第二辐射体1121的电流方向相同,如此得到的第一天线单元111和第二天线单元112的方向图互补,可以保证天线10的MIMO性能。在一些实施方式中,天线10的谐振频段包括B41、N78、N79中的任一种,例如,B41频段包括2500M-2690M;N78频段包括3400MHz-3700MHz;N79频段包括4900MHz-5000MHz。
请参阅图1,在一些实施方式中,第一馈电点122和第二馈电点123之间的路径长度为馈电臂121的延伸长度的五分之二至五分之三,即:D=2/5L~3/5L,其中,D为第一馈电点122和第二馈电点123之间的路径长度,L为馈电臂121的延伸长度。将第一馈电点122和第二馈电点123两者的路径长度设置为馈电臂121的延伸长度的五分之二至五分之三时,当从第一馈电点122输入外部信号时,第二馈电点123的电流强度小于0.5A,并且当从第二馈电点123输入外部信号时,第一馈电点122的电流强度小于0.5A,天线10表现出较小的耦合量,从而使得第一天线单元111和第二天线单元112之间具有较好的隔离度。在一些实施方式中,第一馈电点122和第二馈电点123之间的路径长度为天线10谐振波长的1/2,这样的结构设计,使得当第一馈电点122输入外部信号时,第二馈电点123的电流强度为0A,并且当从第二馈电点123输入外部信号时,第一馈电点122的电流强度为0A,无论从第一馈电点122还是从第二馈电点123输入外部信号,都能够使得天线10的耦合量最小,第一天线单元111和第二天线单元112之间的隔离度达到优异的状态。在一些实施方式中,隔离度达到-28dB以上,相对于现有的天线,隔离度的提高可以达到18dB以上。
请参阅图2和图3,在一些实施方式中,当从第一馈电点122输入外部信号时,第一辐射体1111中的电流方向和第二辐射体1121中的电流方向相反;而当从第二馈电点123输入外部信号时,第一辐射体1111中的电流方向和第二辐射体1121中的电流方向相同。这样的电流方向分布,保证第一天线单元111的方向图和第二天线单元112的方向图互补,从而使得天线10具有良好的MIMO性能。
请参阅图1,在一些实施方式中,第一接地枝节1112与第一辐射体1111远离第二辐射体1121的一端连接;第二接地枝节1122与第二辐射体1121远离第一辐射体1111的一端连接。这样的结构设计,不仅方便第一天线单元111和第二天线单元112分别接地,且有利于第一辐射体1111和第二辐射体1121实现共用。在一些实施方式中,第一馈电枝节1113和第一接地枝节1112间隔设置;同时,第二馈电枝节1123和第二接地枝节1122间隔设置。
请参阅图4,本公开实施例还提供一种电子设备20,电子设备20包括天线10,其中,天线10的具体结构与前文提供的天线10的结构相同,在此不做赘述。
请参阅图4,在一些实施方式中,电子设备20还包括设备主体201和天线支架(图中未标示),天线支架与设备主体201连接,天线10安装于天线支架,从而使得天线10安装于设备主体201。在一些实施方式中,电子设备20还包括供电电池202,天线10安装于供电电池202的壳体外表面。
请参阅图4,在一些实施方式中,设备主体201包括印刷电路板(图中未标示),第一接地枝节1112和第二接地枝节1122分别和印刷电路板的接地点连接,从而实现天线10的接地。
在一些实施方式中,电子设备20可以是智能手机、平板电脑、笔记本电脑、个人数字助理、穿戴式设备、POS机以及车载电脑等。由于电子设备20使用了上述的天线10,因而具有良好的MIMO性能。
本公开实施例提供的天线,包括天线组件和与天线组件连接的馈电组件,其中天线组件包括第一天线单元和第二天线单元,第一天线单元的第一辐射体和第二天线单元的第二辐射体既能够作为独立的辐射体进行单独辐射,又可以作为共同辐射体进行辐射,使得天线具有良好的辐射性能,这样的结构设计不仅可以有效简化天线的布局,减少天线布局的空间,而且可以有效地提高天线的MIMO性能。
应当理解,在本公开说明书和所附权利要求书中使用的术语“和/或”是指相关联列出的项中的一个或多个的任何组合以及所有可能组合,并且包括这些组合。需要说明的是,在本文中,术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含,从而使得包括一系 列要素的过程、方法、物品或者系统不仅包括那些要素,而且还包括没有明确列出的其他要素,或者是还包括为这种过程、方法、物品或者系统所固有的要素。在没有更多限制的情况下,由语句“包括一个……”限定的要素,并不排除在包括该要素的过程、方法、物品或者系统中还存在另外的相同要素。
上述本公开实施例序号仅仅为了描述,不代表实施例的优劣。以上所述,仅为本公开的具体实施例,但本公开的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本公开揭露的技术范围内,可轻易想到各种等效的修改或替换,这些修改或替换都应涵盖在本公开的保护范围之内。因此,本公开的保护范围应以权利要求的保护范围为准。
