Description

用于近场通信的接收端组件及包括该组件的接收设备 技术领域
本实用新型涉及用于近场通信的接收端组件及包括该组件的接 收设备。 背景技术
近场通信 ( Near Field Communication, NFC ) , 又称近巨离无 线通信, 是一种短距离的高频无线通信技术, 允许电子设备之间进 行非接触式点对点数据传输(在 10厘米内)交换数据。 这个技术由 免接触式射频识别(RFID )演变而来, 并向下兼容 RFID。 由于近场 通讯具有天然的安全性, 因此 NFC技术被认为在手机支付等领域具 有很广的应用前景。
NFC设备内置 NFC芯片, 组成 RFID模块的一部分, 可以当作 RFID无源标签使用, 例如用来支付费用; 也可以当作 RFID读写器 使用, 例如用作数据交换与釆集。 NFC技术支持多种应用, 包括移 动支付与交易、 对等式通信及移动中信息访问等。 通过 NFC设备, 人们可以在任何地点、 任何时间, 通过任何设备, 与他们希望得到 的娱乐服务与交易联系在一起, 从而完成付款, 获取海报信息等。 总的来看, NFC设备的应用主要可分为以下四个基本类型: 用于付 款和购票、 用于电子票证、 用于智能媒体以及用于交换、 传输数据。
现有的移动支付 SWP ( Single Wire Protocol, 单线协议) -SD卡 技术方案使得在支持 NFC功能的移动终端(例如, 手机)上便利安 全地实现远程及近场支付功能成为可能。 智能 SD 卡除了具有普通 SD卡的数据存储功能外, 内嵌了一张具有金融安全级别的智能卡作 为支付信息载体, 使银行卡信息安全存储在卡片内。 它也可以像使 用普通 SD卡那样存储用户自己的数据。 与普通的 SD卡相比, 智能 SD 卡在安仝性上有很大的提高, 因此将其与单线实现双工通信的 SWP接口协议结合可以在同时安全可靠地实现远程支付以及基于
NFC的近场支付功能。
然而, 诸如 SWP-SD卡移动支付解决方案的技术虽然具有很高 的安全性和可实现性, 但依旧需要对手机硬件进行比较大的改造。 诸如手机等移动支付终端至少需要增加支持 NFC的模拟前端电路, 而一般增加的模拟前端电路只能集成在手机的主板上。 因此, 用户 需要更换具有 NFC功能的手机才能够支持 SWP-SD卡移动支付方 案, 这使得类似方案的推广投入较大, 在一定程度上限制了近场移 动支付的推广。
因此, 对于尽可能少地改变移动支付终端的硬件结构来实现 NFC近场移动支付的方案有很强的需求。 头用^ r¾i 谷

本实用新型的用于近场通信的接收端组件及包括该组件的接收 设备可以为近场移动支付提供很好的解决方案, 其既可以作为推广 诸如手机支付等移动支付消费习惯的过渡方案, 也可以在移动支付 市场成熟后作为一种可行的解决方案与 SWP-SD卡方案等其他技术 方案并存。 下面将结合具体的实施例来描述本实用新型的方法。 附图说明
本实用新型的前述和其他目标、 特征和优点根据下面对本实用 新型的实施例的更具体的说明将是显而易见的, 这些实施例在附图 中被示意。
图 1 示意性地示出了才艮据本实用新型的第一实施例的用于近场 通信的接收端组件的构成。
图 2示意性地示出了图 1所示的接收端组件的各个部分的布置。 图 3a示意性地示出了 居本实用新型的第二实施例的用于近场 通信的接收端组件的部分; 图 3b示出了图 3a所示部分的等效电路。
图 4示意性地示出了本实用新型所提供的用于近场通信的接收 设备的实施例。 具体实施方式 以下结合附图和具体实施方式进一步详细说明本实用新型。 需 要说明的是, 附图中的各结构只是示意性说明, 用以使本领域普通 技术人员最佳地理解本实用新型的原理, 其不一定按比例绘制。
图 1 示意性地示出了 ^据本实用新型的第一实施例的用于近场 通信的接收端组件的构成。 如在背景技术中所提到的那样, 近场通 信 (NFC ) 又称近距离无线通信, 是一种短距离的高频无线通信技 术, 这个技术由免接触式射频识别 (RFID ) 演变而来, 并向下兼容 RFID。 因此, 与 RFID—样, NFC信息也是通过频谱中无线频率部 分的电磁感应耦合方式来传递的。 在适于 NFC通信的非接触式读卡 器设备上通常布置有 NFC天线, 其为工作在 13.56 MHz频段上的近 场耦合天线, 读写距离 艮短, 因而在接收端也必须布置能够与其匹 配的适于进行磁场耦合的接收天线。
如图 1 所示, 根据本实用新型的第一实施例的接收端组件包括 智能卡 101、 第一线圈 102以及第二线圏 103。 众所周知, 智能卡如 今已被广泛应用在诸如手机、 便携式数字助理(PDA ) 、 膝上型笔 记本、 平板电脑等各式各样的移动终端设备上。 因此, 将智能卡作 为接收天线的栽体可以在对终端设备的硬件结构进行最小改动的情 况下使其具备近距离通信的能力。 终端设备仅需具备智能卡插槽, 而这几乎已经成为了目前大部分电子产品的标准配置。 智能卡可以 包括智能 SD卡、 SIM卡、 智能 miniSD卡、 智能 microSD卡等现有 技术中常见的各种智能卡构造。
第一线圏 102被布置在智能卡 101上, 其被用作接收端天线的 一部分。 在实践中, 可以例如通过将铜制的第一线圏 102直接印制 在封装智能卡芯片的绝缘材料上来实现所述第一线圏。 替代地, 可 以将所述第一线圏与智能卡芯片共面地封装在智能卡的内部, 其中 芯片部分可以被形成在智能卡 101 的除该第一线圏以外的空白部分 上。 不管采用哪一种方式, 这样的贴片式构造都不会使智能卡在外 形和体积上有明显变化, 因此不需要对现有的智能卡插槽等机构进 行改动。 另外, 不管在哪种布置方式下, 都可以将第一线圈 102与 智能卡 101内芯片的天线接口直接相连以对所述芯片进行操作。
事实上, 已知的是诸如第一线圏 102的单个线圏也可以与 NFC 非接触式读卡器设备上的发射天线耦合。 然而, 由于随着半导体技 术的不断发展, 智能卡有明显的小型化发展趋势, 其所能够提供的 用于承载接收天线的空间非常有限, 因此基于诸如智能 microSD卡 的第一线圏 102的面积通常很小, 其与发射端耦合所获得的能量往 往不能满足正常通信的需要。 根据图 1 所示的实施例, 在本实用新 型的接收端组件中还提供了第二线圏 103 ,其与第一线圈 102共同形 成接收天线。
第二线圏 103被布置为靠近所述第一线圈 102并且能够与该第 一线圈 102磁耦合。 显而易见, 该第二线圈 103也必须能够与 NFC 非接触式读卡器设备的发射天线 (线圏)耦合。 根据本实用新型, 该第二线圈 103也同样采用贴片式的构造, 而其面积要大于第一线 圏 102所占据的面积。 该第二线圏可以优选地被布置在与第一线圏 102所处的平面平行的另一平面上,即第一和第二线圏互相平行地被 布置。 另外, 使第二线圈 103所包围的区域在第一线圈 102所处的 平面上的投影完全覆盖所述第一线圏。 在图 2 中示意性地示出了这 样的布置, 其中更优选地将第二线圏布置为其轴线与第一线圏的轴 线大体上重合。
第二线圏 103可以被看作为功率提升线圈, 其与较小的第一线 圏 102之间的互感使得第一线圈的磁场强度增大, 由此增强通过非 接触式近场通信所传送的信号的强度, 从而提供足够的能量保证智 能卡芯片的正常工作。 就这点而言, 例如图 2所示的、 第二线圈 103 的上述布置可以更有效地确保良好的磁耦合效果和能量传输效率。
图 3a示意性地示出了才艮据本实用新型的第二实施例的用于近场 通信的接收端组件的部分; 图 3b示出了图 3a所示部分的等效电路。
如图 3a所示, 才 M居本实用新型的第二实施例的接收端组件中增 加了与第二线圏 301串联的谐振电容器 302, 从而形成图 3b中的串 联谐振电路。 第二线图 301的电感值以及电容 302的电容值应满足 如下谐振公式:

图 4示意性地示出了本实用新型所提供的用于近场通信的接收 设备的实施例。 一般而言, 根据本实用新型的用于近场通信的接收 设备包括智能卡插槽, 以承载带有所述第一线圏的智能卡, 而所述 第二线圈或其与电容构成的 LC谐振电路被固定在接收设备的外壳 上。 该接收设备可以利用各种带有合适的智能卡插槽的移动终端来 实现, 诸如手机、 PDA, 平板电脑等等。
在图 4所示的实施例中,该接收设备为手机 401 , 并且上述接收 端组件被布置在其相应的位置上, 其中带有第一线圈的智能卡部分 被插入手机所带的智能卡插槽中, 而第二线圈或其与电容构成的 LC 谐振电路则被固定在手机后盖 402的内表面上, 该部分可以被实现 为贴片的形式。 根据本实用新型的手机 401可以按照图 4所示的方 位与读卡器 403进行通信, 但应理解的是, 即使把手机 401的正面 对准读卡器 403,本实用新型所提供的接收端组件也可以起到增强通 信的作用。
就目前常见的手机设计而言,所述智能卡可以采用智能 microSD 卡。这一设计能够使近场支付共用 SD卡中智能芯片的安全模块,在

microSD 卡插槽的手机而言, 其都能方便地使用本实用新型所提供 的接收端组件。 除了改用印刷有所述第一线圏的智能 microSD卡并 且将贴片式的第二线圏或其与电容构成的 LC谐振电路固定在其后 盖上之外, 无需对手机本身的硬件进行任何改造。 此外, 由于采用 了无源器件, 即使在手机没电时也可以实现安全的近场支付。
应说明的是, 以上具体实施方式仅用以说明本实用新型的技术
