Description

天线及终端 技术领域 本发明涉及电子通信领域， 具体而言， 涉及一种天线及终端。 背景技术 目前， 随着终端市场的快速发展， 移动运营商之间的竞争也越来越激烈， 因此， 终端产品越来越需要突出其与其他产品之间的不同点， 以发挥出特色， 引起顾客的注 意。 随着终端 （例如手机） 中近场通信 （又称为近距离无线通信） （Near Field Communication,简称为 NFC)功能的普及和用户对无线充电应用的关注度的提升， FC 与无线充电共存技术必然会成为终端设备发展的一个重要方向。但是， 由于 FC天线 的和无线充电的频率都较高， （例如 FC天线可以为 13.56MHZ, 无线充电的频率为 50HZ、 100KHZ等等）， 因此， NFC天线和无线充电的天线都需要占很大的面积。 这 样， 如果 FC天线和无线充电天线共存， 会严重影响终端内部的使用面积， 事实上， 移动终端通常都没有这么大的区域放置这两个天线。 目前的终端产品中， FC功能已经越来越普及。 其具体实现方式为： 利用电磁感 应定律， 通过读 /写 （Reader/Writer) 模式和磁卡 （Card) 模式天线线圈间高频交变磁 场进行数据传输。 无线充电线圈的工作原理与 FC天线基本一致， 此处不再赘述。 然而， 正如上面所述， 终端 （例如手机） FC天线和无线充电天线均需占用很大 的面积空间， 而随着终端向着屏幕更大， 厚度更薄， 待机时间更长的方向发展， 天线 实际可用的面积空间越来越紧张。 针对相关技术中的上述问题， 目前尚未提出有效的解决方案。 发明内容 针对相关技术中，尚无有效地在兼顾终端内部使用面积以及 FC天线和无线充电 天线共存等问题， 本发明提供了一种天线及终端， 以至少解决上述问题。 根据本发明的一个实施例， 提供了一种天线， 包括： 天线本体， 该天线本体包括: 无线充电天线和近场通信（ FC)天线； 无线充电天线和 FC天线一体化设计， 形成 天线本体。 上述 FC天线由所述无线充电天线中的指定走线实现。 上述无线充电天线为实现无线充电功能的无线充电线圈。 上述天线还包括： 开关件， 与所述无线充电天线和所述 FC天线相连接， 设置为 在所述开关件导通时， 与所述无线充电天线相配合， 实现无线充电功能， 以及在所述 开关件断开时， 与所述 FC天线相配合， 实现 FC功能。 上述天线还包括： 铁氧体件， 设置在所述天线本体上， 设置为屏蔽外界信号。 上述天线本体为柔性电路板 (Flexible and Rigid-Flex, 简称为 FPC)。 上述天线应用于移动终端中。 根据本发明的另一个实施例， 提供了一种终端， 包括以上所述的天线。 上述天线设置在所述终端的电池盖上或所述终端的电池上。 通过本发明， 采用无线充电天线和 FC天线一体化设计， 形成天线本体的技术手 段， 解决了相关技术中， 尚无有效地在兼顾终端内部使用面积以及 FC天线和无线充 电天线共存等技术问题， 从而在兼顾终端内部使用面积的情况下， 实现了 FC天线和 无线充电天线的复用。 附图说明 此处所说明的附图用来提供对本发明的进一步理解， 构成本申请的一部分， 本发 明的示意性实施例及其说明用于解释本发明， 并不构成对本发明的不当限定。 在附图 中： 图 1为根据本发明实施例的天线的结构示意图； 图 2为根据本发明实施例的天线本体的外形示意图； 图 3为根据本发明实施例天线的内部走线示意图； 图 4为根据本发明实施例的天线的爆炸示意图； 图 5为根据本发明实施例的开关件的原理示意图。 具体实施方式 下文中将参考附图并结合实施例来详细说明本发明。 需要说明的是， 在不冲突的 情况下， 本申请中的实施例及实施例中的特征可以相互组合。 实施例 1 图 1为根据本发明实施例的天线的结构示意图。 如图 1所示， 该天线包括： 天线 本体 10， 上述天线本体 10包括： 近场通信（NFC)天线 101和无线充电天线 103 ; 无 线充电天线 103和 FC天线 101—体化设计， 形成所述天线本体 10。 需要说明的是， 上述一体化设计的含义可以理解为将无线充电天线 103和 FC天线 101利用一个天线 本体进行复用。 通过上述结构特征， 由于 FC天线和无线充电天线为一体化设计， 因此， 可以节 约由于 FC天线和无线充电天线由于独立设置而占有的终端内部使用面积，从而在兼 顾终端内部使用面积的情况下， 实现了 FC天线和无线充电天线在终端的复用。 在具体应用时，无线充电天线 103和 FC天线 101—体化设计后的整体外形可以 参见图 2所示： 在图 2中， 包括天线本体 10和天线触点 105。 天线本体 10可以是贴 在终端的电池盖上， 且贴与电池的正上方；或者贴在电池本体上， 且是在朝电池盖的那 一面。 天线触点 105与终端中主板上的天线弹片相连。 为了进一步节约终端使用面积， 上述 FC天线 101可以由所述无线充电天线 103 中的指定走线实现。上述无线充电天线可以由实现无线充电功能的无线充电线圈实现。 实现 FC天线和无线充电天线复用的方式有多种，在本发明的一个优选实施方式 中， 可以通过功能开关来实现， 具体地： 如图 1所示， 上述天线还可以包括： 开关件 107， 与所述无线充电天线和所述 FC天线相连接， 设置为在所述开关件导通时， 与 所述无线充电天线相配合，实现无线充电功能，以及在所述开关件断开时，与所述 FC 天线相配合， 实现 FC功能。 在具体应用时， 可以采用图 3所示的结构实现天线的走线： 在图 3中， 10表示天 线的走线 （即天线本体 10)， 107即为上述开关件， 105表示天线触点。 其中， 上述开关件 107可以采用图 5所示的结构实现： 如图 5所示， 图 5中， 501 表示双刀单掷开关。 503 表示传输信号的天线走线， 与上述天线本体 （图中未示出） 连接。 505和 507均是 200欧姆的电阻， 用于防止 FC信号或者无线充电信号流到电 源或者地上去的。当给开关加高电平时， 开关导通， 该天线就用于无线充电功能。当给 开关加低电平时， 该天线就用于 FC功能。 为了保证天线性能， 屏蔽外界信号对天线的影响， 需要在对天线进行屏蔽处理， 具体地， 如图 4所示， 可以在上述天线的天线本体 10上， 设置用于屏蔽外界信号的铁 氧体件 30。在具体应用时， 可以表现为如图 4所示的实现形式： 在图 4中， 天线包括： 可用于实现 FC天线和无线充电天线的铁氧体；该天线的 FPC走线（即天线本体 10); 铁氧体 30 (即铁氧体件 30) 是用来屏蔽主板的信号对天线的影响， FPC走线用于传 输 FC和无线充电的信号以及实现天线功能。 上述天线本体可以采用多种材质制成， 例如可以采用一般的印刷电路板 （Printed Circuit Board, 简称为 PCB)， 还可以采用柔性电路板 FPC制成。 上述实施方式中的天线可以应用在手机等移动终端中。 由于上述天线一般不单独应用， 因此， 本实施例还提供一种终端， 包括： 以上所 述的天线。在具体实施时， 上述天线可以设置在终端的电池盖上或所述终端的电池上。 实施例 2 本实施例以移动终端为例进行说明。 在以下实施例中， 考虑到相关技术中， NFC 天线和无线充电天线占用较多终端的使用面积，以下实施例提供的 FC与无线充电线 圈共存的技术， 在增加终端设备功能的同时不占用额外的空间， 提高设备整体性能和 实用性。以下实施例的主要设计思想在于，将两个天线（即 FC天线和无线充电天线） 进行复用， 以一个天线来同时支持 NFC功能和无线充电功能。 本实施例基于实施例 1 中的天线实现。 本实施例提供一种同时支持 FC 和无线充电功能的移动终端。 该移动终端的构 成： 该移动终端包括移动终端的壳体（包括： 前壳， 中壳和后壳）、 电路板（包括无线 充电电路和 FC电路）、 天线 （包括 NFC天线和无线充电的天线）等等。 该移动终端 可以带 LCD, 也可以不带 LCD。 该移动终端可以支持 LTE、 WCDMA、 GSM、 CDMA 等制式。 该移动终端可以只支持语音通话的功能， 可以只支持数据业务， 也可以同时 支持语音通话和数据业务。 FC 天线和无线充电天线 （即天线本体） 可以贴在后壳上的 （也就是电池盖） ， 而且 FC和无线充电的天线是贴在电池的正上方。 FC天线是无线充电天线是做在 一个线圈里的， 也就是说这个天线（无线充电天线）能同时支持 FC功能和无线充电 的功能。 这个天线包括两个部分： 天线本体 （包括基材和 FPC) 和铁氧体。 其中， 该 铁氧体是同时能支持 FC功能和无线充电功能的铁氧体。 FC天线和无线充电天线 通过天线触电和主板上的弹片相连， 使主板上的电路和天线可以相互传输信号。 从上述描述也可以看出， 上述 FC天线和无线充电天线是二合一， 也就是说用这 个天线（天线本体）能同时支持两个功能。该天线（天线本体）以 FPC的形式实现, FPC 天线包括天线的基材和金属走线部分。 天线走线采用线圈的绕线的形式， 并且采用的 是双面走线。 可以直接贴在电池的本体上天线走线采用线圈的绕线的形式， 并且采用 的是双面走线。 本实施例中， FC功能的工作频率设置为 13.56MHz, 无线充电模块的工作频率可 以为 ΙΟΟΚΗζ左右或 50HZ (但不限于此） ， 从频率上来看无线充电的天线长度会比 FC天线长， 因此， 整个线圈是按照无线充电的功能来调的， 而 FC天线则采用线圈 里的部分走线。 在天线上加一个双刀单掷的开关。 当无线充电功能导通的时候， 开关 闭合。 当 NFC功能导通的时候， 开关断开。 该开关模块是做在天线上的。 这样就实现 了在同一个天线上同时实现 FC功能和无线充电功能。 以上仅为本发明的优选实施例而已， 并不用于限制本发明， 对于本领域的技术人 员来说， 本发明可以有各种更改和变化。 凡在本发明的精神和原则之内， 所作的任何 修改、 等同替换、 改进等， 均应包含在本发明的保护范围之内。 TECHNICAL FIELD The present invention relates to the field of electronic communications, and in particular to an antenna and a terminal.
